- 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 operating temperature of the switch is 32 to 104 degrees Fahrenheit (0 to 40 degrees Celsius). The non-operating temperature of the switch is –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.

Climate-controlled buldings usually maintain an acceptable level of humidity for the switch equipment. 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. System fans cool switches by drawing in air and exhausting air out through various openings in the chassis. Fans also introduce 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. Keep a clean operating environment to reduce the negative effects of dust and other particles.

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

- Do not smoke near the switch.

- Do not eat 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, use 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 these 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, 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. Consult experts in electrical surge suppression and shielding if you have 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 (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. Connect the grounding pad on the switch either directly to the earth-ground connection or to a fully bonded and grounded rack.

When the 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, 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

Create an electrical conducting path between the product chassis and the metal surface of the enclosure, or rack in which it is mounted, or to a grounding conductor. Provide electrical continuity by using thread-forming type mounting screws that remove any paint or non-conductive coatings and establish a metal-to-metal contact. Remove any paint or other non-conductive coatings on the surfaces between the mounting hardware and the enclosure or rack. Clean the surfaces and apply an antioxidant before installation.

Planning for Power Requirements

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

- Two 350-W AC power supplies

- Two 440-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.

The AC power supplies are rated to output up to 350 W but the switch requires less than those amounts of power from the power supply. To operate the switch, you must provision enough power from the power source to cover the requirements of both the switch and a power supply. Typically, this switch and a power supply require about 200 W of power input from the power source, but you must provision as much as 443 W power input from the power source to cover peak demand.

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, verify that each power-source circuit that is used by the switch is dedicated to the switch.

This Warning applies to AC input application.

Note

This Warning applies to DC input application.

Warning

Statement 1005—Circuit Breaker when using DC power supplies

This product relies on the building's installation for short-circuit (overcurrent) protection.

- Ensure that the protective devices are rated not greater than 30A when the switch is powered with regular DC power supplies (rated 48-60VDC).

- Ensure that the protective devices are rated not greater than 10A when the switch is powered with HVDC power supplies (rated 240-350VDC).

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. Position the fan and power supply modules to move the coolant air from the cold aisle to the hot aisle in one of these 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.

Identify the airflow direction of each fan and power supply module by its coloring.

- Blue coloring indicates port-side exhaust airflow.

Note

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

Rack and Cabinet Requirements

Install these 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 these 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).

- Required clearances between the chassis and the edges of its rack or the interior of its cabinet are as follows:

- 4.5 inches (11.4 cm) between the front of the chassis and the interior of the cabinet (required for cabling).

- 3.0 inches (7.6 cm) between the rear of the chassis and the interior of the cabinet (required for airflow in the cabinet if used).

- No clearance is required between the chassis and the sides of the rack or cabinet (no side airflow).

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 it. 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 figure.

Installation Options with Rack-Mount Kits

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

Install the switch using these 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.

- When installing the NXK-ACC-KIT-1RU rack-mount kit, the distance between the outside face of the front mounting rail and the outside face of the back mounting rail should be 25.37 to 33 inches (64.43 to 83.82 cm) to allow for rear-bracket installation.

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

- When installing the N3K-C3064-ACC-KIT rack-mount kit, the distance between the outside face of the front mounting rail and the outside face of the back mounting rail should be 22 to 30 inches (55.88 to 76.2 cm) to allow for rear-bracket installation.

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

Note

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

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, verify 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, verify 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 you are positioning the switch in a rack so that it takes in cold air from the cold aisle and exhausts air to the hot aisle. If there is blue coloring on the fan modules, the switch is configured for port-side exhaust airflow and you must position the module side of the switch in a cold aisle. If there is burgundy coloring on the fan modules, the switch is configured for port-side intake airflow and you must position the port side of the switch in a cold aisle.

- 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, 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 these:

- 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, 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 these:

- Accessory Kit

- Rack-Mount Kit

Step 2

Check for damage and report any discrepancies or damage to your customer service representative. Have this 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

Step 3

Check to be sure that each of the power supply and the fan tray modules have the expected direction of airflow as follows:

- Port-side intake airflow modules

- Burgundy (fan modules and AC power supplies)

- Port-side exhaust airflow modules

- Blue (fan modules and AC power supplies)

Note

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

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

To install the switch:

- attach front and rear mounting brackets to the switch,

- 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

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

- Verify that the switch rack-mount kit includes these parts:

- Front rack-mount brackets (2)

- Rear rack-mount brackets (2)

- Slider rails (2)

- M4 x 0.7 x 8-mm Phillips pan-head screws (10)

- 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:

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

- 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 figure 1). 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).

t

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. 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. If it does not fit, the back rack-mount bracket is not needed.

Step 2

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

Step 3

Install the slider rails on the rack or cabinet:

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. 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.

Ensure that the slider rails are at the same level. 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:

1. Using two 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 figure 4).

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) of torque.

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 Using the N3K-C3064-ACC-KIT 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-mount brackets to the switch as follows:

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

Step 2

Install the two rear rack-mount brackets on the chassis as follows:

1. Align the two screw holes on a rear rack-mount bracket to the middle two screw holes in the remaining six screw holes on a side of the chassis. If you are aligning the guide to holes that are near the port connections end of the chassis, see Callout 3 in the previous figure. Otherwise, see Callout 7 in the previous figure.

2. Attach the guide to the chassis using two M4 screws (see Callout 4 or 8 in the previous figure). Tighten the screws to 12 in-lb (1.36 N·m) of torque.

3. Repeat Step 2 for the other rear rack-mount bracket on the other side of the switch.

Step 3

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 4

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 two 12-24 screws or two 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.

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:

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 figure 1).

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) of torque.

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

Provide an electrical conducting path between the product chassis and the metal surface of the enclosure or rack in which it is mounted or to a grounding conductor. To ensure electrical continuity, use thread-forming type mounting screws that remove any paint or non-conductive coatings and establish a metal-to-metal contact. Remove any paint or other non-conductive coatings on the surfaces between the mounting hardware and the enclosure or rack. Clean the surfaces and apply an antioxidant before installation.

Ground the chassis, which is required if the rack is not grounded. Attach 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.

Step 3

Secure the grounding lug to the chassis grounding pad with two M4 screws, see the previous figure 1. 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 the 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:

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

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

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

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

5. Place the power cable ground-wire terminal ring on the ground 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 DC 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.

Chapter 4. Connecting the Switch to the Network

- Connecting to the Network

- Preparing for Network Connections

- Connecting to a Console

- Connecting the Management Interface

- Connecting Interface Ports to Other Devices

Connecting to the Network

You need to connect the following ports when connecting the switch to the network:

- Console port—A direct local management connection used to initially configure the switch

- Management ports—An online management connection

- Uplink and downlink ports—Connections to hosts and servers

Caution

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.

Preparing for Network Connections

When preparing your site for network connections to your switch, consider the following for each type of interface and gather all the required equipment before connecting the ports:

- Cabling required for each interface type

- Distance limitations for each signal type

- Additional interface equipment required

Connecting to a Console

You can connect the switch to a console to perform the following functions:

- Configuring the switch using the CLI

- Monitoring network statistics and errors

- Configuring SNMP agent parameters

- Downloading software updates

Note

We recommend that you use this port to create a local management connection to set the IP address and other initial configuration settings before connecting the switch to the network for the first time.

The console port on the switch is an RS-232 port with an RJ-45 interface. This is an asynchronous (async) serial port; any device connected to this port must be capable of asynchronous transmission.

Caution

The console port can be used to connect to a modem. If you do not connect it to a modem, connect it either before powering the switch on or after the switch has completed the boot process.

Before you begin

Before you connect the switch to a console, ensure that you have the following:

- Computer terminal that supports VT100 terminal emulation. The terminal emulation software (such as HyperTerminal or Procomm Plus) makes communication between the switch and a computer possible during setup and configuration.

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

Connect the DB-9 connector on the other end of the cable to the computer serial port.

What to do next

You are ready to configure the switch.

Connecting the Management Interface

Before you begin

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

Procedure

Step 1

Connect the appropriate modular cable to on the switch.

Step 2

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

Connecting Interface Ports to Other Devices

After you perform the initial configuration for the switch and create a management connection, you are ready to connect the interface ports on the switch to other devices. Depending on the types of interface ports on the switch, you will need to use interface cables with QSFP+, SFP+, or SFP transceivers or RJ-45 connectors to connect the switch to other devices.

The transceivers used with many fiber-optic cables come separated from their cables. To prevent damage to the fiber-optic cables and their transceivers, we recommend that you keep these transceivers disconnected from their fiber-optic cables when installing the transceiver in the interface port. Before removing a transceiver for a fiber-optic cable, you must remove the cable from the transceiver.

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 during installation and provides an ESD port to which you can connect your wrist strap.

- Do not remove and insert a transceiver more often than is 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) is increased by contamination and should be kept below 0.35 dB.

- Clean these parts before installation 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.

Warning

Statement 1051—Laser Radiaation

Invisible laser radiation may be emitted from disconneted fibers or connectors. Do not stare into beams or view directly with optical instruments

- Installing QSFP+ Transceivers

Installing QSFP+ Transceivers

The QSFP+ transceiver module can have either a bail-clasp latch or a pull-tab latch.

Caution

The QSFP+ transceiver module is a static-sensitive device. Always use an ESD wrist strap or similar individual grounding device when handling QSFP+ transceiver modules or coming into contact with system modules.

Procedure

Step 1

Attach an ESD wrist strap to yourself and a properly grounded point on the chassis or the rack. Follow its instructions for use.

Step 2

Remove the QSFP+ transceiver module from its protective packaging.

Step 3

Remove the dust cover from the port end of the transceiver.

Step 4

Check the label on the QSFP+ transceiver module body to verify that you have the correct model for your network.

Step 5

For optical QSFP+ transceivers, remove the optical bore dust plug and set it aside.

Step 6

For transceivers equipped with a bail-clasp latch, do the following:

1. Keep the bail-clasp aligned in a vertical position.

2. Align the QSFP+ transceiver in front of the module's transceiver socket opening and carefully slide the QSFP+ transceiver into the socket until the transceiver makes contact with the socket electrical connector.

Step 7

For QSFP+ transceivers equipped with a pull-tab, do the following:

1. Hold the transceiver so that the identifier label is on the top.

2. Align the QSFP+ transceiver in front of the module's transceiver socket opening and carefully slide the QSFP+ transceiver into the socket until the transceiver makes contact with the socket electrical connector.

Chapter 5. Replacing Components

- Replacing a Fan Module

- Replacing a Power Supply Module

Replacing a Fan Module

You can replace a fan module while the switch is operating, as long as you perform the replacement within one minute. If you cannot perform the replacement within one minute, leave the original fan module in the chassis to maintain the designed airflow until you have the replacement fan module on hand and can perform the replacement.

Caution

If you are replacing a module during operations, verify the replacement fan module has the correct direction of airflow. This means that it has the same airflow direction as the other modules in the chassis. Also, verify that the airflow direction takes in air from a cold aisle and exhausts air to a hot aisle. Otherwise, the switch can overheat and shutdown.

If you are changing the airflow direction of all the modules in the chassis, shutdown the switch before replacing all the fan and power supply modules with modules using the other airflow direction. During operations, all of the modules must have the same direction of airflow.

- Removing a Fan Module

- Installing a Fan Module

Removing a Fan Module

Caution

The fans might still be turning when you remove the fan assembly from the chassis. Keep fingers, screwdrivers, and other objects away from the openings in the fan assembly's housing.

Procedure

Step 1

On the fan module that you are removing, press the two sides of the fan module handle together, and pull on the handles enough to unseat it from its connectors.

Step 2

Holding the handle, pull the module out of the chassis.

Caution

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

Installing a Fan Module

Before you begin

- A fan slot must be open and ready for the new fan module to be installed.

- If the switch is operating, you must have a new fan module on hand and ready to install within one minute of removing the original fan module.

- The new fan module must have the same airflow direction as the other fan and power supply modules installed in the switch.

Procedure

Step 1

Holding the fan module by its handle, align the back of the fan module (the side with the electrical connectors) to the open fan slot in the chassis.

Step 2

Slide the fan module into the slot until it clicks in place.

Step 3

Verify that the Status (STS) LED turns on and becomes green.

Replacing a Power Supply Module

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

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

- Wiring the DC Input Power Source

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.

- The replacement power supply must have the same wattage and airflow direction as the power supply being replaced. Do not mix AC, DC, HVAC/HVDC power supplies in the same switch.

- 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

- The replacement power supply must have the same wattage and airflow direction as the power supply being replaced. Do not mix AC, DC, HVAC/HVDC power supplies in the same switch.

- 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

- The replacement power supply must have the same wattage and airflow direction as the power supply being replaced. Do not mix AC, DC, HVAC/HVDC power supplies in the same switch.

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.

Wiring the DC Input Power Source

Procedure

Step 1

Using a wire-stripping tool, strip each of the four wires from the DC-input power source to the appropriate length for the terminals.

Warning

Statement 1025—

Use copper conductors only.

Step 2

Using a Panduit crimping tool, crimp the fork-type terminals to the copper conductor, 90C, 12-AWG DC poser input wires.

Step 3

Connect the DC-input power terminals to the terminal blocks. Make sure to match the polarity (negative to negative, positive to positive) when connecting the wires to the terminal blocks. Connect the ground wire to a grounded metal rack or to earth ground if the switch is not in a grounded rack.

DC Source A Isolated from Source B with No Common Ground

DC Source A and Source B Connections with Common Ground

Step 4

Torque all terminal block screws to 11 lbf-in.

Step 5

Replace the terminal block safety cover.

Step 6

Move the DC poser source circuit-breakers to the ON position.

Step 7

Confirm that the poser supply DC OK and PS OK LEDs are 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

Install the switch in these 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 using 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 using racks that have obstructions (such as power strips). The obstructions could impair access to field-replaceable units (FRUs).

General Requirements for Cabinets and Racks

The cabinet or rack must meet these 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 these 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.

For the specific rack dimension information for each possible rack-mount, see Installation Options with Rack-Mount Kits.

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 these 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 these 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, 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.
