- Overview

Overview

The Cisco Nexus 93108TC-FX3 switch (N9K-C93108TC-FX3) is a 1-rack unit (RU) switch that supports 2.16 Tbps of bandwidth and 1.2 Bpps. The 48 10GBASE-T downlink ports on the 93108TC-FX3 can be configured to work as 100-Mbps or 10-Gbps ports. The uplink can support up to six 40- and 100-Gbps ports, or a combination of 10-, 25-, 40, and 100-Gbps connectivity, offering flexible migration options for spine-leaf-APIC deployment in data centers. This switch supports the following ports:

- 48 100M/10GBASE-T ports (ports 1-48)

- 6 40/100-Gigabit ports QSFP28 (ports 49-54)

- Two management ports (one 10/100/1000BASE-T port and one SFP port)

- One console port (RS-232)

- 1 USB port

This switch includes the following user-replaceable components:

- Fan modules (four) with the following airflow choices:

- Port-side exhaust fan module with blue coloring (NXA-SFAN-35CFM-PE)

- Port-side intake fan module with burgundy coloring (NXA-SFAN-35CFM-PI)

Note

This switch will power down due to a fan-policy trigger if fewer than 3 fans are operational.

Note

Each fan module has two rotors. The switch can function normally if one rotor inside the any one fan module fails. In case of more than one rotor failure, the switch will issue a warning and power down in 2 minute.

Note

This switch runs with +1 redundancy mode, so that if one fan fails, the switch can sustain operation. But if a 2nd fan fails, this switch is not designed to sustain operation. Hence before waiting for major threshold temperature to be hit, the switch will power down due to Powered-down due to fan policy trigger.

- Power supply modules (two—One for operations and one for redundancy [1+1]) with the following choices:

- 500-W port-side intake AC power supply with burgundy coloring (NXA-PAC-500W-PI)

- 500-W port-side exhaust AC power supply with blue coloring (NXA-PAC-500W-PE)

- 1200-W port-side intake HVAC/HVDC dual-direction power supply with white coloring (N9K-PUV-1200W)

- 930-W port-side intake DC power supply with burgundy coloring (NXA-PDC-930W-PI)

- 930-W port-side exhaust DC power supply with blue coloring (NXA-PDC-930W-PE)

Note

All fan modules and power supplies must use the same airflow direction.

Grounding pad

Depending on whether you plan to position the ports in a hot or cold aisle, you can order the fan and power supply modules with port-side intake or port-side exhaust airflow. For port-side intake airflow, the fan and power supplies have burgundy coloring. For port-side exhaust airflow, the fan and power supplies have blue coloring.

The fan and power supply modules are field replaceable. You can replace one fan module or one power supply module during operations so long as the other modules are installed and operating. If you have only one power supply installed, you can install the replacement power supply in the open slot before removing the original power supply.

Caution

If the switch has port-side intake airflow (burgundy coloring for fan modules), you must locate the ports in the cold aisle. If the switch has port-side exhaust airflow (blue coloring for fan modules), you must locate the ports in the hot aisle. If you locate the air intake in a hot aisle, the switch can overheat and shut down.

Chapter 2. Preparing the Site

- Temperature Requirements

- Humidity Requirements

- Altitude Requirements

- Dust and Particulate Requirements

- Minimizing Electromagnetic and Radio Frequency Interference

- Shock and Vibration Requirements

- Grounding Requirements

- Planning for Power Requirements

- Airflow Requirements

- Rack and Cabinet Requirements

- Clearance Requirements

Temperature Requirements

The switch requires an operating temperature of 32 to 104 degrees Fahrenheit (0 to 40 degrees Celsius). If the switch is not operating, the temperature must be between –40 to 158 degrees Fahrenheit (–40 to 70 degrees Celsius).

Humidity Requirements

High humidity can cause moisture to enter the switch. Moisture can cause corrosion of internal components and degradation of properties such as electrical resistance, thermal conductivity, physical strength, and size. The switch is rated to withstand from 5- to 95-percent (nonoperating) and 5- to 90-percent (operating) relative humidity.

Buildings in which the climate is controlled by air-conditioning in the warmer months and by heat during the colder months usually maintain an acceptable level of humidity for the switch equipment. However, if the switch is located in an unusually humid location, use a dehumidifier to maintain the humidity within an acceptable range.

Altitude Requirements

Altitude rating is 10,000 ft (3048 m). For China, it is 6,562 ft (2000 m).

Dust and Particulate Requirements

Exhaust fans cool power supplies and system fans cool switches by drawing in air and exhausting air out through various openings in the chassis. However, fans also ingest dust and other particles, causing contaminant buildup in the switch and increased internal chassis temperature. Dust and particles can act as insulators and interfere with the mechanical components in the switch. A clean operating environment can greatly reduce the negative effects of dust and other particles.

In addition to keeping your environment free of dust and particles, follow these precautions to avoid contamination of your switch:

- Do not permit smoking near the switch.

- Do not permit food or drink near the switch.

Minimizing Electromagnetic and Radio Frequency Interference

Electromagnetic interference (EMI) and radio frequency interference (RFI) from the switch can adversely affect other devices, such as radio and television (TV) receivers. Radio frequencies that emanate from the switch can also interfere with cordless and low-power telephones. Conversely, RFI from high-power telephones can cause spurious characters to appear on the switch monitor.

RFI is defined as any EMI with a frequency above 10 kHz. This type of interference can travel from the switch to other devices through the power cable and power source or through the air as transmitted radio waves. The Federal Communications Commission (FCC) publishes specific regulations to limit the amount of EMI and RFI that are emitted by computing equipment. Each switch meets these FCC regulations.

To reduce the possibility of EMI and RFI, follow these guidelines:

- Cover all open expansion slots with a blank filler plate.

- Always use shielded cables with metal connector shells for attaching peripherals to the switch.

When wires are run for any significant distance in an electromagnetic field, interference can occur to the signals on the wires with the following implications:

- Bad wiring can result in radio interference emanating from the plant wiring.

- Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the chassis and even create an electrical hazard by conducting power surges through lines into equipment.

Note

To predict and prevent strong EMI, you need to consult experts in radio frequency interference (RFI).

The wiring is unlikely to emit radio interference if you use a twisted-pair cable with a good distribution of grounding conductors. If you exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.

Caution

If the wires exceed the recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse that is caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic switches. You will want to consult experts in electrical surge suppression and shielding if you had similar problems in the past.

Shock and Vibration Requirements

The switch has been shock- and vibration-tested for operating ranges, handling, and earthquake standards.

Grounding Requirements

The switch is sensitive to variations in voltage that is supplied by the power sources. Overvoltage, undervoltage, and transients (or spikes) can erase data from memory or cause components to fail. To protect against these types of problems, ensure that there is an earth-ground connection for the switch. You can connect the grounding pad on the switch either directly to the earth-ground connection or to a fully bonded and grounded rack.

When chassis is properly installed in a grounded rack, the switch is grounded because it has a metal-to-metal (no paint, stain, dirt, or anything else on it) connection to the rack. Alternatively, you can ground the chassis by using a customer-supplied grounding cable that meets your local and national installation requirements. For U.S. installations, we recommend 6-AWG wire. Connect your grounding cable to the chassis with a grounding lug (provided in the switch accessory kit) and to the facility ground.

Note

You automatically ground AC power supplies when you connect them to AC power sources. For DC power supplies, you must connect a grounding wire when wiring the power supply to the DC power source.

Note

An electrical conducting path shall exist between the product chassis and the metal surface of the enclosure or rack in which it is mounted or to a grounding conductor. Electrical continuity shall be provided by using thread-forming type mounting screws that remove any paint or non-conductive coatings and establish a metal-to-metal contact. Any paint or other non-conductive coatings shall be removed on the surfaces between the mounting hardware and the enclosure or rack. The surfaces shall be cleaned and an antioxidant applied before installation.

Planning for Power Requirements

The switch includes two power supplies (1-to-1 redundancy with current sharing) in one of the following combinations:

- Two 500-W AC power supplies

- Two 1200-W HVAC/HVDC power supplies

- Two 930-W DC power supplies

Note

For 1+1 redundancy, you must use two power sources and connect each power supply to a separate power source.

Note

Some of the power supply modules have rating capabilities that exceed the switch requirements. When calculating your power requirements, use the switch requirements to determine the amount of power that is required for the power supplies.

To minimize the possibility of circuit failure, make sure that each power-source circuit that is used by the switch is dedicated to the switch.

Warning

Statement 1033—Safety Extra-Low Voltage (SELV)—IEC 60950/ES1–IEC 62368 DC Power Supply

To reduce the risk of electric shock, connect the unit to a DC power source that complies with the SELV requirements in IEC 60950-based safety standards or ES1 and PS1 requirements in IEC 62368-based safety standards or to a Class 2 power supply.

Note

We recommend 8-AWG wire for DC installations in the U.S.

Airflow Requirements

The switch is positioned with its ports in either the front or the rear of the rack depending on your cabling and maintenance requirements.

To identify the airflow options for your switch, see the user-replaceable components in the Overview section of this document.

You must have fan and power supply modules that move the coolant air from the cold aisle to the hot aisle in one of the following ways:

- Port-side exhaust airflow—Cool air enters the chassis through the fan and power supply modules in the cold aisle and exhausts through the port end of the chassis in the hot aisle.

- Port-side intake airflow—Cool air enters the chassis through the port end in the cold aisle and exhausts through the fan and power supply modules in the hot aisle.

You can identify the airflow direction of each fan and power supply module by its coloring as follows:

- Blue coloring indicates port-side exhaust airflow.

- Burgundy coloring indicates port-side intake airflow.

Note

To prevent the switch from overheating and shutting down, you must position the air intake for the switch in a cold aisle. The fan and power supply modules must have the same direction of airflow. If you must change the airflow direction for the switch, you must shutdown the switch before changing the modules.

Rack and Cabinet Requirements

You can install the following types of racks or cabinets for your switch:

- Standard perforated cabinets

- Solid-walled cabinets with a roof fan tray (bottom-to-top cooling)

- Standard open four-post Telco racks

Work with your cabinet vendors to determine which of their cabinets meet the following requirements or see the Cisco Technical Assistance Center (TAC) for recommendations:

- Use a standard 19-inch (48.3-cm), four-post Electronic Industries Alliance (EIA) cabinet or rack with mounting rails that conform to English universal hole spacing per section 1 of the ANSI/EIA-310-D-1992 standard.

- The depth of a four-post rack must be 24 to 32 inches (61.0 to 81.3 cm) between the front and rear mounting rails (for proper mounting of the bottom-support brackets or other mounting hardware).

Also, you must have power receptacles that are located within reach of the power cords that are used with the switch.

Warning

Statement 1048—Rack Stabilization

The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before installation or servicing. Failure to stabilize the rack can cause bodily injury.

Clearance Requirements

Provide the chassis with adequate clearance between the chassis and any other rack, device, or structure so that you can properly install the chassis. Provide the chassis with adequate clearance to route cables, provide airflow, and maintain the switch. For the clearances required for an installation of this chassis in a four-post rack, see the following figure.

Installation Options with Rack-Mount Kits

The rack-mount kit enables you to install the switch into racks of varying depths. You can position the switch with easy access to either the port connections or the fan and power supply modules.

You can install the switch using the following rack-mount options:

- Rack-mount kit (NXK-ACC-KIT-1RU) which you can order from Cisco. This option offers you easy installation, greater stability, increased weight capacity, added accessibility, and improved removability with front and rear removal.

- Rack-mount kit (N3K-C3064-ACC-KIT) which you can order from Cisco.

The rack or cabinet that you use must meet the requirements listed the in General Requirements for Cabinets and Racks section.

Note

You are responsible for verifying that your rack and rack-mount hardware comply with the guidelines that are described in this doc.

Airflow Considerations

The switch comes with fan and power supply modules that have either port-side intake or port-side exhaust airflow for cooling the switch. If you are positioning the port end of the switch in a cold aisle, make sure that the switch has port-side intake fan modules with burgundy coloring. If you are positioning the fan and power supply modules in a cold aisle, make sure that the switch has port-side exhaust fan modules with blue colorings. All fan modules must have the same direction of airflow.

Installation Guidelines

When installing the switch, follow these guidelines:

- Ensure that there is adequate clearance space around the switch to allow for servicing the switch and for adequate airflow.

- Ensure that the chassis can be adequately grounded. If the switch is not mounted in a grounded rack, we recommend connecting the system ground on the chassis directly to an earth ground.

- Ensure that the site power meets the power requirements for the switch. If available, you can use an uninterruptible power supply (UPS) to protect against power failures.

Caution

Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with the switch, which can have substantial current draw fluctuations because of fluctuating data traffic patterns.

- Ensure that circuits are sized according to local and national codes. Typically, this often requires one or both of the following:

- AC power supplies typically require at least a 15-A or 20-A AC circuit, 100 to 240 VAC, and a frequency of 50 to 60 Hz.

Caution

To prevent loss of input power, ensure the total maximum loads on the circuits supplying power to the switch are within the current ratings for the wiring and breakers.

Unpacking and Inspecting the Switch

Before you install the switch, be sure to unpack and inspect the switch for damage or missing components. If anything is missing or damaged, contact your customer service representative immediately.

Tip

Keep the shipping container in case the chassis requires shipping at a later time.

Before you begin

Before you unpack the switch and before you handle any switch components, be sure that you are wearing a grounded electrostatic discharge (ESD) strap. To ground the strap, attach it directly to an earth ground or to a grounded rack or grounded chassis (there must be a metal-to-metal connection to the earth ground).

Procedure

Step 1

Compare the shipment to the equipment list provided by your customer service representative and verify that you have received all items, including the following:

- Accessory Kit

Step 2

Check for damage and report any discrepancies or damage to your customer service representative. Have the following information ready:

- Invoice number of shipper (see packing slip)

- Model and serial number of the damaged unit

- Description of damage

- Effect of damage on the installation

Installing the Switch Using the NXK-ACC-KIT-1RU Rack-Mount Kit

To install the switch, you must attach front and rear mounting brackets to the switch, install slider rails on the rear of the rack, slide the switch onto the slider rails, and secure the switch to the front of the rack. Typically, the front of the rack is the side easiest to access for maintenance.

Note

You must supply the eight 10-32 or 12-24 screws required to mount the slider rails and switch to the rack.

Before you begin

- You have inspected the switch shipment to ensure that you have everything ordered.

- Make sure that the switch rack-mount kit includes the following parts:

- Front rack-mount brackets (2)

- Rear rack-mount brackets (2)

- Slider rails (2)

- M4 x 0.7 x 8-mm Phillips countersink screws (12)

- The rack is installed and secured to its location.

Procedure

Step 1

Install two front rack-mount brackets and the two rear rack-mount brackets to the switch as follows:

1. Determine which end of the chassis is to be located in the cold aisle as follows:

- If the switch has port-side intake modules (fan modules with burgundy coloring), position the switch so that its ports will be in the cold aisle.

- If the switch has port-side exhaust modules (fan modules with blue coloring), position the switch so that its fan and power supply modules will be in the cold aisle.

2. Position the front rack-mount bracket and the rear rack-mount bracket so that its screw holes are aligned to the screw holes on the side of the chassis.

Note

You can align the holes in the rack-mount bracket to the holes on the side of the chassis (see the two ways to mount these brackets on a typical chassis, in following figure). The holes that you use depend on the requirements of your rack and the amount of clearance required for interface cables (3 inches [7.6 mm] minimum) and module handles (1 inch [2.5 mm] minimum).

3. Secure the front-mount bracket and the back-mount bracket to the chassis using four M4 screws and tighten each screw to 12 in-lb (1.36 N·m) of torque.

4. Repeat Step 1 for the other front rack-mount bracket and the other back-mount bracket on the other side of the switch and be sure to position that bracket the same distance from the front of the switch.

Note

Depending on the chassis depth, the back rack-mount bracket may not fit. In that case the back rack-mount bracket is not needed.

Step 2

If you are not installing the chassis into a grounded rack, you must attach a customer-supplied grounding wire to the chassis as explained in the Grounding the Chassis section. If you are installing the chassis into a grounded rack, you can skip this step.

Step 3

Install the slider rails on the rack or cabinet as follows:

1. Determine which two posts of the rack or cabinet you should use for the slider rails. Of the four vertical posts in the rack or cabinet, two will be used for the front mount brackets attached to the easiest accessed end of the chassis, and the other two posts will have the slider rails.

2. Position a slider rail at the desired level on the back side of the rack and use 12-24 screws or 10-32 screws, depending on the rack thread type, to attach the rails to the rack (see the following figure). Tighten 12-24 screws to 30 in-lb (3.39 N·m) of torque and tighten 10-32 screws to 20 in-lb (2.26 N·m) of torque.

3. Repeat Step 3 to attach the other slider rail to the other side of the rack.

To make sure that the slider rails are at the same level, you should use a level tool, tape measure, or carefully count the screw holes in the vertical mounting rails.

Step 4

Insert the switch into the rack and attach it as follows:

1. Holding the switch with both hands, position the two rear rack-mount brackets on the switch between the rack or cabinet posts that do not have slider rails attached to them (see the following figure).

2. Align the two rear rack-mount guides on either side of the switch with the slider rails installed in the rack. Slide the rack-mount guides onto the slider rails, and then gently slide the switch all the way into the rack until the front rack-mount brackets come in contact with two rack or cabinet posts.

3. Holding the chassis level, insert screws (12-24 or 10-32, depending on the rack type) in each of the two front rack-mount brackets (using a total of six screws) and into the cage nuts or threaded holes in the vertical rack-mounting rails (see the following figure).

4. Tighten the 10-32 screws to 20 in-lb (2.26 N·m) or tighten the 12-24 screws to 30 in-lb (3.39 N·m).

Step 5

If you attached a grounding wire to the chassis grounding pad, connect the other end of the wire to the facility ground.

Installing the Switch into a Two-Post Rack Using the NXK-ACC-KIT-1RU Rack-Mount Kit

To install the switch, you must attach front mounting brackets to the switch and secure the switch to the front of the rack. Typically, the front of the rack is the side easiest to access for maintenance.

Note

This is not the preferred rack installation method. This method may not be earthquake safe and will not be NEBS compliant.

Note

You must supply the six 10-32 or 12-24 screws required to mount the rails to the rack.

Before you begin

- You have inspected the switch shipment to ensure that you have everything ordered.

- Make sure that the switch rack-mount kit includes the following parts:

- Front rack-mount brackets (2)

- Rear rack-mount brackets (2) (not needed for this procedure)

- Slider rails (2) (not needed for this procedure)

- M4 x 0.7 x 8-mm Phillips countersink screws (12)

- The rack is installed and secured to its location.

Procedure

Step 1

Install two front rack-mount brackets to the switch as follows:

1. Determine which end of the chassis is to be located in the cold aisle as follows:

- If the switch has port-side intake modules (fan modules with burgundy coloring), position the switch so that its ports will be in the cold aisle.

- If the switch has port-side exhaust modules (fan modules with blue coloring), position the switch so that its fan and power supply modules will be in the cold aisle.

2. Position the front rack-mount bracket and the rear rack-mount bracket so that its screw holes are aligned to the screw holes on the side of the chassis.

Note

You can align the holes in the rack-mount bracket to the holes on the side of the chassis (see the two ways to mount these brackets on a typical chassis, in following figure). The holes that you use depend on the requirements of your rack and the amount of clearance required for interface cables (3 inches [7.6 mm] minimum) and module handles (1 inch [2.5 mm] minimum).

3. Secure the front-mount bracket to the chassis using four M4 screws and tighten each screw to 12 in-lb (1.36 N·m) of torque.

4. Repeat Step 1 for the other front rack-mount bracket on the other side of the switch and be sure to position that bracket the same distance from the front of the switch.

Step 2

If you are not installing the chassis into a grounded rack, you must attach a customer-supplied grounding wire to the chassis as explained in the Grounding the Chassis section. If you are installing the chassis into a grounded rack, you can skip this step.

Step 3

Insert the switch into the rack and attach it as follows:

1. Holding the switch with both hands, position the brackets on the switch between the cabinet posts (see the following figure).

2. Gently slide the switch all the way into the rack until the front rack-mount brackets come in contact with the cabinet posts.

Note

If you attached a grounding cable to the chassis, you will need to bend one of the rack-mounts slightly to allow the grounding lug to go behind the rail.

3. Holding the chassis level, insert screws (12-24 or 10-32, depending on the rack type) in each of the two front rack-mount brackets (using a total of six screws) and into the cage nuts or threaded holes in the vertical rack-mounting rails (see the following figure).

4. Tighten the 10-32 screws to 20 in-lb (2.26 N·m) or tighten the 12-24 screws to 30 in-lb (3.39 N·m).

Step 4

If you attached a grounding wire to the chassis grounding pad, connect the other end of the wire to the facility ground.

Installing the Airflow Sleeve (N9K-AIRFLOW-SLV)

The airflow sleeve (N9K-AIRFLOW-SLV) is installed to allow proper airflow, so that the switch is properly cooled. This airflow sleeve is only compatible with rack mount kit (N3K-C3064-ACC-KIT).

Note

You supply the screws to mount the airflow sleeve.

Before you begin

- Verify that your shipment is complete.

- Install your rack in a secure location.

Procedure

Insert the airflow sleeve into the rack and attach it as follows:

1. Holding the airflow sleeve (N9K-AIRFLOW-SLV) with both hands, position it in front of the fan side of the chassis.

2. Holding the airflow sleeve level, insert screws (12-24 or 10-32, depending on the rack type) in each of the two front rack-mount flanges (using a total of two screws) and into the cage nuts or threaded holes in the vertical rack-mounting rails (see the following figure).

3. Tighten the 10-32 screws to 20 in-lb (2.26 N·m) or tighten the 12-24 screws to 30 in-lb (3.39 N·m).

Grounding the Chassis

The switch chassis is automatically grounded when you properly install the switch in a grounded rack with metal-to-metal connections between the switch and rack.

Note

An electrical conducting path shall exist between the product chassis and the metal surface of the enclosure or rack in which it is mounted or to a grounding conductor. Electrical continuity shall be provided by using thread-forming type mounting screws that remove any paint or non-conductive coatings and establish a metal-to-metal contact. Any paint or other non-conductive coatings shall be removed on the surfaces between the mounting hardware and the enclosure or rack. The surfaces shall be cleaned and an antioxidant applied before installation.

You can also ground the chassis, which is required if the rack is not grounded, by attaching a customer-supplied grounding cable. Attach the cable to the chassis grounding pad and the facility ground.

Warning

Statement 1024—Ground Conductor

This equipment must be grounded. To reduce the risk of electric shock, never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

Warning

Statement 1046—Installing or Replacing the Unit

To reduce risk of electric shock, when installing or replacing the unit, the ground connection must always be made first and disconnected last.

Before you begin

Before you can ground the chassis, you must have a connection to the earth ground for the data center building.

Procedure

Step 1

Use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of the covering from the end of the grounding wire. We recommend 6-AWG wire for the U.S. installations.

Step 2

Insert the stripped end of the grounding wire into the open end of the grounding lug. Use a crimping tool to crimp the lug to the wire, see the following figure. Verify that the ground wire is securely attached to the grounding lug by attempting to pull the wire out of the crimped lug.

1

Chassis grounding pad

3

2 M4 screws are used to secure the grounding lug to the chassis

2

Grounding cable, with 0.75 in. (19 mm) of insulation that is stripped from one end, which is inserted into the grounding lug and crimped in place

Step 3

Secure the grounding lug to the chassis grounding pad with two M4 screws, see the previous figure. Tighten the screws to 11 to 15 in-lb (1.24 to 1.69 N·m) of torque.

Step 4

Prepare the other end of the grounding wire and connect it to the facility ground.

Starting the Switch

You start the switch by connecting it to its dedicated power source. If you need n+n redundancy, you must connect each power supply in a switch to a different power source.

Note

This equipment is designed to boot up in less than 30 minutes, dependent on its neighboring devices being fully up and running.

Before you begin

- The switch must be installed and secured to a rack or cabinet.

- The switch must be adequately grounded.

- The rack must be close enough to the dedicated power source so that you can connect the switch to the power source by using a designated power cables.

- You have the designated power cables for the power supplies that you are connecting to the dedicated power sources.

Note

Depending on the outlet receptacle on your AC power distribution unit, you might need an optional jumper power cord to connect the switch to your outlet receptacle.

- The switch is not connected to the network (this includes any management or interface connections).

- The fan and power supply modules are fully secured in their chassis slots.

Procedure

Step 1

For any AC power supply, do the following:

1. Using the recommended AC power cable for your country or region, connect one end to the AC power supply.

2. Connect the other end of the power cable to the AC power source.

Step 2

For any HVAC/HVDC power supply, connect it to a power source as follows:

1. Using the recommended high voltage power cable for your country or region, connect the Anderson Power Saf-D-Grid connector on the power cable to the power receptacle on the power supply. Make sure that the connector clicks when fully pushed into the receptacle.

2. Connect the other end of the power cable to a power source.

- When connecting to an HVAC power source, insert the plug in a receptacle for the HVAC power source.

- When connecting to an HVDC power source, do the following:

1. Place the power cable ground-wire terminal ring on the ground terminal for the power source and secure them with a terminal nut.

2. Verify that the power is turned off at a circuit breaker for the power source terminals.

3. Remove the nuts from each of the terminal posts for the power supply.

4. Place the power cable negative-wire terminal ring on the negative terminal for the power source and secure them with a terminal nut.

5. Place the power cable positive-wire terminal ring on the positive terminal for the power source and secure them with a terminal nut.

6. If there is a safety cover for the power source terminals, place and secure it over the terminals to avoid an electrical shock hazard.

7. Turn on the power at the power source circuit breaker.

Step 3

For any LVDC power supply, do the following:

1. Turn off the circuit breaker for the power source to avoid an electrical shock hazard.

2. Verify that the power cable wires from the power source are connected to a connector block.

3. Insert the connector block into the receptacle on the power supply. Make sure that the connector block clicks when fully inserted in the receptacle and does not pull out.

4. If there is a safety cover for the terminals, place and secure it over the terminals to avoid an electrical shock hazard.

5. Turn on the power at the circuit breaker for the DC power source.

Step 4

Verify that the power supply LED is on and green.

Step 5

Listen for the fans; they should begin operating when the power supply is powered.

Step 6

After the switch boots, verify that the following LEDs are lit:

- On the fan modules, the Status (STA or STS) LED is green.

If a fan module Status LED is not green, try reinstalling the fan module.

- After initialization, the switch chassis Status (labeled as STA or STS) LED is green.

Step 7

Verify that the system software has booted and the switch has initialized without error messages.

A setup utility automatically launches the first time that you access the switch and guides you through the basic configuration. For instructions on how to configure the switch and check module connectivity, see the appropriate Cisco Nexus 9000 Series configuration guide.

- Connecting Leaf Switches to APICs

- Connecting Leaf Switches to Spine Switches

- Installing a Gigabit Ethernet module (GEM)

- Migration of Nodes From a First Generation Switch to a Second Generation Switch

- Setting Up an Optional Console Interface

- Setting Up an Optional Management Connection

- Maintaining Transceivers and Optical Cables

ACI Fabric Topology

The ACI fabric topology includes the following major components:

- Application Centric Infrastructure Controller (APIC) appliance (cluster of APICs)

- Leaf switches (for switch compatibility, please see the data sheets).

- Spine switches (for switch compatibility, please see the data sheets).

For additional information, please see the Cisco APIC Installation, Upgrade, and Downgrade Guide.

Note

To prevent sub-optimal forwarding between endpoints, connect every leaf switch in the fabric to every spine switch in the same fabric.

As shown in the following figure, each APIC is connected to one or two leaf switches and each leaf switch should be connected to every spine switch in the same fabric.

Connections Between APIC Clusters, Leaf Nodes, and Spine Nodes

Preparing to Connect to Other Devices

When preparing to connect the fabric devices, consider the following for each type of interface, and gather all of the required equipment before making the connections:

- Cabling type required for each interface type

- Distance limitations for each signal type

- Additional interface equipment required

Note

When running power and data cables in overhead or subfloor cable trays, we strongly recommend that you locate power cables and other potential noise sources as far away as practical from network cabling that terminates on Cisco equipment. In situations where long parallel cable runs cannot be separated by at least 3.3 feet (1 meter), we recommend that you shield any potential noise sources by housing them in a grounded metallic conduit.

The optical transceivers that are not already assembled to their cables come separate from their cables. To prevent these transceivers and their cables from being damaged, we recommend that you keep the transceivers disconnected from their cables when installing them in ports and then insert the optical cable into the transceiver. When removing transceivers from ports, remove their cables before removing the transceivers.

To maximize the effectiveness and life of your transceivers and optical cables, do the following:

- Wear an ESD-preventative wrist strap that is connected to an earth ground whenever handling transceivers. The switch is typically grounded when you install transceivers and provides an ESD port to which you can connect your wrist strap. If you cannot find an ESD port, connect the wrist strap to an earth ground (such as the grounding connection for the chassis).

- Do not remove or insert a transceiver more often than necessary. Repeated removals and insertions can shorten its useful life.

- Keep the transceivers and fiber-optic cables clean and dust free to maintain high signal accuracy and to prevent damage to the connectors. Attenuation (loss of light) increases with contamination and should be kept below 0.35 dB.

- Clean these parts before installing them to prevent dust from scratching the fiber-optic cable ends.

- Clean the connectors regularly; the required frequency of cleaning depends upon the environment. In addition, clean connectors if they are exposed to dust or accidentally touched. Both wet and dry cleaning techniques can be effective; refer to your site's fiber-optic connection cleaning procedures.

- Do not touch the ends of connectors. Touching the ends can leave fingerprints and cause other contamination.

- Inspect routinely for dust and damage. If you suspect damage, clean and then inspect fiber ends under a microscope to determine if damage has occurred.

Connecting Leaf Switches to APICs

You must downlink one or two (recommended for redundancy) Cisco Nexus 9300 platform ACI-mode leaf switches to each Application Policy Infrastructure Controller (APIC) in your ACI fabric. The type of virtual interface card (VIC) installed on the APIC determines the types of interface cables that you can use to connect the leaf switches to the APICs.

- The VIC 1225T module supports copper connectors, copper cables, and switches with copper downlink ports (such as: Cisco Nexus 93108TC-FX switche).

- The VIC 1225 module supports optical transceivers, optical cables, and switches with optical downlink ports (such as: Cisco Nexus 93600CD-GX switche).

- The VIC 1455 module supports optical transceivers, optical cables, and switches with optical downlink ports (such as: Cisco Nexus 93600CD-GX switche).

Note

Breakout ports cannot be used for Cisco APIC connectivity.

Before you begin

The APIC and leaf switches in the fabric must be fully installed in their racks and grounded.

Procedure

Step 1

Connect an interface cable to one of the two to four ports on the virtual interface card (VIC) installed on the APIC. If the cable is not already assembled to its transceivers, insert the transceiver into the VIC port and then connect the optical interface cable to the transceiver.

- For a VIC 1225T 10GBASE-T copper module, use 10GBASE-T cables with RJ-45 connectors.

- For a VIC 1225 optical module, use one of the following sets of transceivers and cables:

- Cisco 10GBASE-LR transceivers (SFP-10G-LR) supporting a link length of up to 6.1 miles (10 km)

- Cisco 10GBASE-SR transceivers (SFP-10G-SR) supporting the following link lengths:

- Using 2000 MHz MMF (OM3) for up to 984 feet (300 m)

- Using 4700 MHz MMF (OM4) for up to 1312 feet (400 m)

- Cisco SFP+ Active Optical Cables (SFP-10G-AOCxM [where x=1, 3, 5, 7 for lengths in meters])

- Cisco SFP+ Twinax Cables (SFP-H10GB-CUxM [where x=7 for lengths in meters])

- For a VIC 1455 SFP28 module, 10-Gigabit only, use one of the following sets of transceivers and cables:

- Cisco 10GBASE-LR transceivers (SFP-10G-LR) supporting a link length of up to 6.1 miles (10 km)

- Cisco 10GBASE-SR transceivers (SFP-10G-SR) supporting the following link lengths:

- Using 2000 MHz MMF (OM3) for up to 984 feet (300 m)

- Using 4700 MHz MMF (OM4) for up to 1312 feet (400 m)

- Cisco SFP+ Active Optical Cables (SFP-10G-AOCxM [where x=1, 2, 3, 5, 7, or 10 for lengths in meters])

- Cisco SFP+ Twinax Cables (SFP-H10GB-CUxM [where x=1, 2, 3, 5, 7, or 10 for lengths in meters])

Note

The VIC 1455 has 4 ports, port-1, port-2, port-3, and port-4 from left to right.

- All ports must have the same speed, either 10-Gigabit or 25-Gigabit.

- Port-1 and port-2 is one pair, corresponding to eth2-1 on APIC and port-3 and port-4 is another pair, corresponding to eth2-2 on APIC. Only one connection is allowed for each pair. For example, you can connect one cable to either port-1 or port-2, and connect another cable to either port-3 or port-4 (please do not connect two cables on any pair).

To determine which transceivers, adapters, and cables support this switch, see the Cisco Transceiver Modules Compatibility Information document.

To see the transceiver specifications and installation information, see Transceiver Module Installation Guides.

Step 2

Connect the other end of the interface cable to a downlink port on a leaf switch.

- For a Cisco 10GBASE-LR or -SR transceiver and cable, insert the transceiver into a downlink optical port on a leaf switch before connecting the cable to the transceiver.

- For Cisco SFP+ Active Optical Cables, insert the transceiver on the cable into a downlink optical port on a leaf switch.

- For a 10GBASE-T copper cable, insert the RJ-45 connector on the cable into a downlink BASE-T port on a leaf switch.

Note

To determine which transceivers, adapters, and cables support this switch, see the Cisco Transceiver Modules Compatibility Information document.

Connecting Leaf Switches to Spine Switches

For optimal forwarding between endpoints, you must connect each leaf switch to every spine switch in the same ACI fabric.

To determine which transceivers, adapters, and cables support this switch, see the Cisco Transceiver Modules Compatibility Information document.

To see the transceiver specifications and installation information, see Transceiver Module Installation Guides.

Warning

Statement 1055—Class 1/1M Laser

Invisible laser radiation is present. Do not expose to users of telescopic optics. This applies to Class 1/1M laser products.

Warning

Statement 1056—Unterminated Fiber Cable

Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not view directly with optical instruments. Viewing the laser output with certain optical instruments, for example, eye loupes, magnifiers, and microscopes, within a distance of 100 mm, may pose an eye hazard.

Before you begin

- The leaf and spine switches in the fabric (such as: N9k-C9364C, N9K-C9332C, N9K-C9316D-GX, and N9K-C9332D-GX2B) must be fully installed in their racks and grounded.

- If there are modular switches in the fabric, their ACI-mode line cards must already be installed. The line cards can be of the following types:

- 32-port 100-Gigabit (such as: N9K-X9732C-EX)

- 36-port 100-Gigabit (such as: N9K-X9736C-FX)

- 16-port 400-Gigabit (such as: N9K-X9716D-GX)

Note

You cannot include NX-OS line cards in the same chassis when running in ACI mode.

Note

Multiple uplinks from a leaf switch to a spine switch is supported. A symmetrical topology is recommended so that all devices have equal access to resources.

Procedure

Step 1

For the transceivers with removable cables, make sure that the transceivers are separated from their interface cables.

Step 2

Insert the appropriate transceiver into an active uplink port on the leaf switch.

Step 3

Insert the same type of transceiver in the spine switch port on the line card.

Step 4

For transceivers with removable cables, insert the interface cable into the open end of each of those transceivers.

Step 5

Repeat Steps 1 through 4 for each spine switch in the ACI fabric.

The leaf switch is connected to each spine switch in the ACI fabric.

Step 6

Repeat Steps 1 through 5 for each leaf switch in the ACI fabric.

Each leaf switch in the ACI fabric is connected to each spine switch in the network,

The fabric automatically implements Equal Cost Multi-Pathing (ECMP) and enables all links. You do not need to configure the links.

Installing a Gigabit Ethernet module (GEM)

Procedure

Step 1

Clear the switch's current configuration by using the setup-clean-config command.

Step 2

Power off the switch by disconnecting the power.

Step 3

Replace the current GEM card with the new GEM card.

Step 4

Power on the switch.

Migration of Nodes From a First Generation Switch to a Second Generation Switch

You have first generation Cisco Nexus 9000 series switches that may or may not be comprising a virtual port channel (vPC). You are migrating to second generation Cisco Nexus 9000 series switches using the same cables.

First generation Cisco Nexus 9000 series switches include those switches that do not contain -EX, -FX, or -GX in the product ID.

Second generation Cisco Nexus 9000 series switches include those switches that have the -EX, -FX, -GX, or later suffix in the product ID.

To migrate the first generation switches to second generation switches, you must perform the steps in this procedure.

To determine which transceivers, adapters, and cables support this switch, see the Cisco Transceiver Modules Compatibility Information document.

To see the transceiver specifications and installation information, see Transceiver Module Installation Guides.

Before you begin

- Move any Cisco Application Policy Infrastructure Controllers (APICs) that are connected to the first generation switches that you are migrating to any other switches in the fabric and wait for the Cisco APIC cluster to become "Fully Fit."

- The following migration paths are supported:

1. Migrating from first generation Cisco Application Centric Infrastructure (ACI) switches to second generation Cisco ACI switches that are running the same software release.

2. Migrating from first generation Cisco ACI switches to second generation Cisco ACI switches that are running different software releases.

The second migration path is required where the existing switches are not supported on the new release that is required for the new switches. For example, if you want to migrate from the first generation Cisco ACI switches, such as Cisco Nexus 9300 (with the -E suffix or without any suffixes in the product ID) that are no longer supported starting on Cisco ACI switch 15.0(1) or later releases, to some of the new switches that are supported only from 15.0(1) or later.

When the first generation switches are comprising a vPC, complete the following mandatory prerequisite steps before you proceed with the second migration path:

1. Due to potential traffic loss, it is recommended that that you perform the vPC migration during a maintenance window.

2. Before you perform this procedure, the Auto Firmware Update policy must be disabled.

3. Upgrade the Cisco APIC cluster to the 4.2(7v) release if the cluster is running an older release. Also upgrade the first generation switches to the 14.2(7v) release. Wait for the fabric to converge.

4. Upgrade the Cisco APIC cluster to 5.2(7f) release and wait for the cluster to become "Fully Fit."

5. Ensure that the new second generation switches are preloaded and running the equivalent release as the Cisco APICs, that is 15.2(7f) release. Other than source and target version software releases 4.2(7v)/14.2(7v) and 5.2(7f)/15.2(7f), no other software releases are supported for this migration procedure.

Note

- The number of ports and port types of the second generation switches must match the first generation switch that you are replacing. If the number does not match, then you must change the configuration to accommodate the new ports or port types. This is also applicable if you migrate the hardware while retaining the same software version.

- To migrate first generation non-vPC leaf switches or first generation spine switches to second generation switches, follow Step 1 through Step 6 in the procedure outlined below. vPC-related information is not applicable for this migration.

If you must migrate a first generation non-vPC leaf switch or a first generation spine switch to a second generation switch, the requirement of the source and target software release 4.2(7v)/14.2(7v) and 5.2(7f)/15.2(7f) is not required. Ensure that the Cisco ACI fabric is running the required software release that supports the second generation switch PID.

Procedure

Step 1

From the Cisco APIC GUI, perform the Remove From Controller operation for the operational secondary vPC switch node.

The Cisco APIC clean reboots the switch. Wait for about 10 minutes for this operation to finish. This action prompts all traffic to use the other first generation switch for data traffic.

Note

There will be a loss of traffic for a few seconds for the operational secondary vPC when you perform the Remove From Controller operation.

Step 2

Disconnect the cabling from the first generation switch that you just removed.

Step 3

Uninstall the first generation switch by reversing the order of the steps in the "Installing the Switch Chassis" section of the switch-specific Hardware Installation Guide.

Step 4

Install the second generation switch by following the steps in the "Installing the Switch Chassis" section of the switch-specific Hardware Installation Guide.

Step 5

Connect the loose cabling that you removed from the first generation switch to the same ports on the second generation switch.

Step 6

Register the new second generation switch with the Cisco APIC.

Register the new node with the same node name and node ID. This switch becomes part of the fabric. The Cisco APIC pushes the policies to the new switch and keeps down the vPC legs because there is a mismatch of the generation of switches. At this point, the vPC primary continues to send the data traffic.

Step 7

Before you proceed to Step 8, wait for 10 to 15 minutes for the new switch to download the configurations.

Step 8

From the Cisco APIC GUI, perform the Remove From Controller operation for the vPC primary. The Cisco APIC clean reboots the switch.

Wait for about 10 minutes for this operation to finish. The vPC leg on the second generation switch, which the Cisco APIC kept down earlier, comes up. This action prompts all traffic to move to the new second generation switch. The vPC ports on the new second generation switch can take a few minutes to come up, during which time there will be traffic drops. The duration of traffic drops varies by the scale and flows in the fabric.

Step 9

Disconnect the cabling from the first generation switch.

Step 10

Uninstall the first generation switch as you did in Step 3.

Step 11

Install the second generation switch as you did in Step 4.

Step 12

Connect the loose cabling as you did in Step 5.

Step 13

Register the new second generation switch with the Cisco APIC.

Register the new node with the same node name and node ID. This switch becomes part of the fabric. The Cisco APIC pushes policies to the new switch and the vPC legs comes up and starts passing traffic.

Setting Up an Optional Console Interface

You can optionally set up a console interface for performing the initial configuration of the switch. To do this, use the interface cable provided in the accessory kit to connect the switch to your console device. You can connect the console port on the switch to a modem. If you do not connect it to a modem, make the connection either before powering up the switch or after completing the boot process for the switch.

Before you begin

The console device must support VT100 terminal emulations and asynchronous transmissions.

Procedure

Step 1

Configure the terminal emulator program to match each of the following default port characteristics:

- 9600 baud

- 8 data bits

- 1 stop bit

- No parity

Step 2

Insert the RJ-45 connector on the interface cable found in the accessory kit into the RS-232 port on the switch and insert the DB-9 connector on the other end of the cable to the serial port on the console device.

What to do next

You can now perform the initial configuration for the switch (see the Cisco ACI Getting Started Guide).

Setting Up an Optional Management Connection

You can optionally set up an out-of-band management connection for monitoring and troubleshooting purposes. To do this, depending on your switch, you connect either the RJ-45 management port or the SFP management port on the switch to an external hub, switch, or router.

Before you begin

To prevent an IP address conflict, you must complete the initial configuration for the switch and establish an IP address before you create the management connection.

Procedure

Step 1

Connect the interface cable to a management port on the switch.

Step 2

Connect the other end of the cable to an external hub, switch, or router.

Maintaining Transceivers and Optical Cables

Transceivers and fiber-optic cables must be kept clean and dust free to maintain high signal accuracy and prevent damage to the connectors. Contamination increases attenuation (loss of light) and should be below 0.35 dB.

Consider the following maintenance guidelines:

- Transceivers are static sensitive. To prevent ESD damage, wear an ESD-preventative wrist strap that is connected to the grounded chassis.

- Do not remove and insert a transceiver more often than is necessary. Repeated removals and insertions can shorten its useful life.

- Keep all optical connections covered when not in use. Clean them before using to prevent dust from scratching the fiber-optic cable ends.

- Do not touch the ends of connectors. Touching the ends can leave fingerprints and cause other contamination.

- Clean the connectors regularly; the required frequency of cleaning depends upon the environment. In addition, clean connectors if they are exposed to dust or accidentally touched. Both wet and dry cleaning techniques can be effective; refer to the fiber-optic connection cleaning procedures for your site.

- Inspect routinely for dust and damage. If you suspect damage, clean and then inspect fiber ends under a microscope to determine if damage has occurred.

Chapter 5. Replacing Components

- Replacing a Power Supply Module

Replacing a Power Supply Module

The switch requires two power supplies for redundancy. With one power supply providing the necessary power for operations, you can replace the other power supply during operations so long as the new power supply has the same airflow direction as the other modules in the chassis.

You can replace a power supply with another supported power supply that has the same power source type as the other installed power supply. Additionally, the airflow direction of the power supply must match or conform to the airflow direction of the installed fan modules. For the airflow direction used by the switch, see the coloring of the fan modules.

- Replacing an AC Power Supply

- Replacing a High Voltage (HVAC/HVDC) Power Supply

- Replacing a DC Power Supply

Replacing an AC Power Supply

You can replace an AC power supply during operations so long as the other power supply provides to the switch.

Before you begin

Note

You can determine the airflow direction by looking at the coloring of the latch on each power supply. AC power supplies with burgundy latches have port-side intake airflow direction, and power supplies with blue latches have port-side exhaust airflow direction.

- An AC power source must be within reach of the power cable that will be used with the replacement power supply. If you are using n+n power redundancy, there must be a separate power source for each power supply installed in the chassis.

- There must be an earth ground connection to the chassis that you are installing the replacement module. AC power supplies connected to AC power sources are automatically grounded through their power cable.

Procedure

Step 1

Remove an AC power supply as follows:

1. Holding the plug for the power cable, pull the plug out from the power receptacle on the power supply and verify that both power supply LEDs are off.

2. Grasp the power supply handle while pressing the colored release latch towards the power supply handle.

3. Place your other hand under the power supply to support it while you slide it out of the chassis.

Caution

Do not touch the electrical connections on the back side of the module and prevent anything else from coming into contact with and damaging the connectors.

Step 2

Install the replacement power supply as follows:

1. Holding the replacement power supply with one hand underneath the module and the other hand holding the handle, turn the power supply so that its release latch is on the right side and align the back end of the power supply (the end with the electrical connections) to the open power supply slot before carefully sliding the power supply all the way into the slot until it clicks into place.

Note

If the power supply does not fit into the open slot, turn the module over before sliding it carefully into the open slot.

2. Test the installation by trying to pull the power supply out of the slot without using the release latch.

If the power supply does not move out of place, it is secured in the slot. If the power supply moves, carefully press it all the way into the slot until it clicks in place.

3. Attach the power cable to the electrical outlet on the front of the power supply.

4. Make sure that the other end of the power cable is attached to the appropriate power source for the power supply.

Note

Depending on the outlet receptacle on your power distribution unit, you might need the optional jumper cable to connect the switch to your outlet receptacle.

5. Verify that the power supply is operational by making sure that the power supply LED is green.

Replacing a High Voltage (HVAC/HVDC) Power Supply

You can replace an HVACHVDC power supply during operations so long as the other power supply provides power to the switch.

Before you begin

- An HVAC/HVDC power source must be within reach of the power cable that will be used with the replacement power supply. If you are using n+n power redundancy, there must be a separate power source for each power supply installed in the chassis.

- There must be an earth ground connection to the chassis in which you are installing the replacement power supply. HVAC/HVDC power supplies connected to AC power sources are automatically grounded by their power cable when connected to the power supply and AC power source. HVAC/HVDC power supplies connected to DC power sources have Saf-D-Grid power cables with three connectors on the power source end--you connect one of those connectors to the earth ground.

Procedure

Step 1

Remove an HVAC/HVDC power supply as follows:

1. Turn off the circuit breaker for the power feed to the power supply that you are replacing.

Be sure that the LEDs turn off on the power supply that you are removing.

2. Remove the power cable from the power supply by pressing the tab on the top of the Anderson Power SAF-D-Grid connector and pull the cable and connector out of the power supply.

3. Grasp the power supply handle while pressing the colored release latch towards the power supply handle.

4. Place your other hand under the power supply to support it while you slide it out of the chassis.

Caution

Do not touch the electrical connections on the back side of the module and prevent anything else from coming into contact with and damaging the connectors.

Step 2

Install the replacement power supply as follows:

1. Holding the replacement power supply with one hand underneath the module and the other hand holding the handle, turn the power supply so that its release latch is on the right side and align the back end of the power supply (the end with the electrical connections) to the open power supply slot before carefully sliding the power supply all the way into the slot until it clicks into place.

Note

If the power supply does not fit into the open slot, turn the module over before sliding it carefully into the open slot.

2. Test the installation by trying to pull the power supply out of the slot without using the release latch.

If the power supply does not move out of place, it is secured in the slot. If the power supply moves, carefully press it all the way into the slot until it clicks in place.

3. Attach the Saf-D-Grid end of the power cable to the electrical outlet on the front of the power supply.

4. Make sure that the other end of the power cable is attached to the appropriate power source for the power supply.

- For an HVAC power source, plug the other end of the power cable into the power source.

- For a HVDC power source, verify that the circuit breaker is turned off and then connect each of the three cable connectors to the appropriate DC and grounding terminals on the power source. If there is a cover plate for the DC terminals, install the plate to prevent accidental contact with the terminals.

5. If using an HVDC power source, turn on the circuit breaker for the power source.

6. Verify that the power supply is operational by making sure that the power supply LED is green.

Replacing a DC Power Supply

You can replace an DC power supply during operations so long as the other power supply provides power to the switch.

Before you begin

- Note

You can determine the airflow direction by looking at the coloring of the latch on each power supply. AC power supplies with burgundy latches have port-side intake airflow direction, and power supplies with blue latches have port-side exhaust airflow direction.

- An DC power source must be within reach of the power cables that will be used with the replacement power supply. If you are using n+n power redundancy, there must be a separate power source for each power supply installed in the chassis.

- There must be an earth ground connection to the chassis in which you are installing the replacement power supply. If the switch is mounted properly in a grounded rack then there is no need to ground the PSU. Some DC power supplies connected to DC power sources have three power cables (two for DC power and one for grounding). Some, like the (NXA-PDC-1100W) only have two power cables (both for DC power).

- We recommend 8-AWG wire for DC installation in the U.S.

- All DC power supplies have reverse polarity protection. When you inadvertently connect the input power (+) to the DC PSU’s – terminal and the input power – to the DC PSU’s (+) terminal, the PSU will not be damaged and will operate fine after the input power feeds are correctly wired.

Procedure

Step 1

Remove a DC power supply as follows:

1. Turn off the circuit breaker for the power feed to the power supply that you are replacing.

Be sure that the LEDs turn off on the power supply that you are removing.

2. Remove the DC power connector block from the power supply by doing the following:

1. Push the orange plastic button on the top of the connector block inward toward the power supply.

2. Pull the connector block out of the power supply.

3. Grasp the power supply handle while pressing the release latch towards the power supply handle.

4. Place your other hand under the power supply to support it while you slide it out of the chassis.

Caution

Do not touch the electrical connections on the back side of the module and prevent anything else from coming into contact with and damaging the connectors.

Step 2

Install the replacement power supply as follows:

1. Holding the replacement power supply with one hand underneath the module and the other hand holding the handle, turn the power supply so that its release latch is on the right side and align the back end of the power supply (the end with the electrical connections) to the open power supply slot before carefully sliding the power supply all the way into the slot until it clicks into place.

Note

If the power supply does not fit into the open slot, turn the module over before sliding it carefully into the open slot.

2. Test the installation by trying to pull the power supply out of the slot without using the release latch.

If the power supply does not move out of place, it is secured in the slot. If the power supply moves, carefully press it all the way into the slot until it clicks in place.

3. Attach the power connector block end of the power cable to the electrical outlet on the front of the power supply.

4. Turn on the circuit breaker for the power source.

5. Verify that the power supply is operational by making sure that the power supply LED is green.

Rack Specifications

- Overview of Racks

- General Requirements for Cabinets and Racks

- Requirements Specific to Standard Open Racks

- Requirements Specific to Perforated Cabinets

- Cable Management Guidelines

Overview of Racks

You can install the switch in the following types of cabinets and racks, assuming an external ambient air temperature range of 0 to 104°F (0 to 40°C):

- Standard perforated cabinets

- Solid-walled cabinets with a roof fan tray (bottom to top cooling)

- Standard open racks

Note

If you are selecting an enclosed cabinet, we recommend one of the thermally validated types, either standard perforated or solid-walled with a fan tray.

Note

We do not recommend that you use racks that have obstructions (such as power strips), because the obstructions could impair access to field-replaceable units (FRUs).

General Requirements for Cabinets and Racks

The cabinet or rack must also meet the following requirements:

- Standard 19-inch (48.3 cm) (two- or four-post EIA cabinet or rack, with mounting rails that conform to English universal hole spacing per section 1 of ANSI/EIA-310-D-1992). For more information, see Requirements Specific to Perforated Cabinets.

- The minimum vertical rack space requirement per chassis is:

- For a one RU (rack unit) switch, 1.75 inches (4.4 cm)

- For a one and a half RU (rack unit) switch, 2.63 (6.68 cm)

- For a two RU (rack unit) switch, 3.5 inches (8.8 cm)

- For a three RU (rack unit) switch, 5.25 inches (13.3 cm)

- The width between the rack-mounting rails must be at least 17.75 inches (45.0 cm) if the rear of the device is not attached to the rack. For four-post EIA racks, this measurement is the distance between the two front rails.

Four-post EIA cabinets (perforated or solid-walled) must meet the following requirements:

- The minimum spacing for the bend radius for fiber-optic cables should have the front-mounting rails of the cabinet offset from the front door by a minimum of 3 inches (7.6 cm).

- The distance between the outside face of the front mounting rail and the outside face of the back mounting rail should be 23.0 to 30.0 inches (58.4 to 76.2 cm) to allow for rear-bracket installation.

Requirements Specific to Standard Open Racks

If you are mounting the chassis in an open rack (no side panels or doors), ensure that the rack meets the following requirements:

- The minimum vertical rack space per chassis must be equal to the rack unit (RU) of the chassis. One rack unit is equal to 1.75 inches (4.4 cm).

- The distance between the chassis air vents and any walls should be 2.5 inches (6.4 cm).

Requirements Specific to Perforated Cabinets

A perforated cabinet has perforations in its front and rear doors and side walls. Perforated cabinets must meet the following requirements:

- The front and rear doors must have at least a 60 percent open area perforation pattern, with at least 15 square inches (96.8 square cm) of open area per rack unit of door height.

- The roof should be perforated with at least a 20 percent open area.

- The cabinet floor should be open or perforated to enhance cooling.

The Cisco R Series rack conforms to these requirements.

Cable Management Guidelines

To help with cable management, you might want to allow additional space in the rack above and below the chassis to make it easier to route all of the fiber optic or copper cables through the rack.
