See the Cisco IOS XR software release notes for additional software release information at:

http://www.cisco.com/en/US/products/ps5763/prod_release_notes_list.html

Hardware Revision Requirements

To ensure compatibility with the software, your Ethernet PLIM should have a specific hardware revision number. This number is printed on a label affixed to the component side of the PLIM. The hardware revision number can also be displayed using the show diag command. Minimum revision numbers are listed in the above table.

About Physical Layer Interface Modules

A physical layer interface module (PLIM) provides the packet interfaces for the routing system. Optics modules on the PLIM contain ports to which fiber-optic cables are connected. User data is received and transmitted through the PLIM ports and converted between the optical signals (used in the network) and the electrical signals (used by Cisco CRS-1 components).

Each PLIM is paired with a modular services card (MSC) through the chassis midplane. The MSC provides Layer 3 services for the user data, and the PLIM provides Layer 1 and Layer 2 services. An MSC can be paired with different PLIMs to provide a variety of packet interfaces and port densities (for example, OC-192c/STM-64c POS and 10-GE).

MSCs and PLIMs are installed on opposite sides of the line card chassis and mate through the chassis midplane. Each MSC and PLIM pair is installed in corresponding chassis slots in the chassis (on opposite sides of the chassis). The chassis midplane enables you to remove and replace an MSC without disconnecting the user cables on the PLIM.

The Cisco CRS-1 supports the following number of PLIMs for each chassis type. You can mix and match PLIM types in the chassis.

The 16-slot chassis supports from 1 to 16 PLIMs.
The 8-slot chassis supports from 1 to 8 PLIMs.
The 4-slot chassis supports from 1 to 4 PLIMs.

For additional information about the operation of MSCs and PLIMs, see Cisco CRS-1 Carrier Routing System Line Card Chassis System Description for the 16-slot, 8-slot, or 4-slot chassis.

Ethernet PLIMs

Ethernet PLIMs provide data packet buffering, Layer 2 processing, and multiplexing and demultiplexing of the GE data streams, including processing for VLANs and back-pressure signals from the MSC. In addition, PLIMs include power and clocking components, voltage and temperature sensors, and an identification EEPROM that stores initial configuration and PLIM hardware information.

The Ethernet PLIMs all share the following features:

ARPA, IEEE 802.2/SAP, and IEEE 802.3/SNAP encapsulation
IEEE 802.x flow control
IEEE 802.1q VLAN support (with jumbo frames)
IEEE 802.1p tagging
Source and destination MAC and VLAN accounting
Online insertion and removal (OIR)
Cisco IOS XR CLI, S1008P, XML, and Craft Works Interface (CWI) network management tools
Compliance with network and industry standards

For additional features and specifications, see the data sheets at:

The interface connectors on the 42-port 1-GE SFP PLIM are eight individual fiber-optic receivers that support SFP modules. Each port can send and receive traffic using the optical fiber connections.

SFP Module Connections

The small form-factor pluggable (SFP) module is an input/output (I/O) device that plugs into the GE optical slots on the 20-Port 1-GE Flex PLIM or the 42-port 1-GE SFP PLIM, linking the port with a 1000BASE-X fiber-optic network.

The 20-Port 1-GE Flex PLIM and 42-port 1-GE SFP PLIM accept only the SFP modules listed as supported in this document. An SFP module check is run every time an SFP is inserted, and only SFP modules that pass this check can be used by the 20-port 1-GE PLIM or the 42-port 1-GE SFP PLIM.

SFP modules exist for technologies other than GE and for products other than the 20-Port 1-GE Flex PLIM and the 42-port 1-GE SFP PLIM. However, the information in this document pertains only to SFP modules that plug into the 20-Port 1-GE Flex PLIM or 42-port 1-GE SFP PLIM ports.

The SFP module has a receiver port (RX) and a transmitter port (TX) that compose one optical interface.

SFP-GE-S Modules

The 1000BASE-SX (short-wavelength) module operates on standard multimode fiber-optic link spans of up to 500 m on 50/125 micron MMF (multimode fiber) and 300 m on 62.5/125 micron MMF.

SFP-GE-L Modules

The 1000BASE-LX/LH (long-wavelength/long-haul) module interfaces fully comply with theIEEE 802.3z 1000BASE-LX standard. However, their higher optical quality allows them to reach 6.2 miles (10 km) over single-mode fiber (SMF) versus the 3.1 miles (5 km) specified in the standard.

SFP-GE-Z Modules

The 1000BASE-ZX (extended-wavelength) module operates on ordinary single-mode fiber-optic link spans of up to 49.7 miles (80 km). Link spans of up to 62.1 miles (100 km) are possible using premium single-mode fiber or dispersion-shifted single-mode fiber. (Premium single-mode fiber has a lower attenuation per unit length than ordinary single-mode fiber; dispersion-shifted single-mode fiber has both lower attenuation and less dispersion.)

The 1000BASE-ZX module must be coupled to single-mode fiber-optic cable, which is the type of cable typically used in long-haul telecommunications applications. The 1000BASE-ZX module does not operate correctly when coupled to multimode fiber, and it is not intended to be used in environments in which multimode fiber is frequently used (for example, building backbones or horizontal cabling).

The 1000BASE-ZX module is intended to be used as a Physical Medium Dependent (PMD) component for GE interfaces found on various switch and router products. It operates at a signaling rate of 1250 Mbaud, transmitting and receiving 8B/10B encoded data.

When shorter lengths of single-mode fiber are used, it may be necessary to insert an inline optical attenuator in the link to avoid overloading the receiver. Use the following guidelines:

Insert a 10-dB inline optical attenuator between the fiber-optic cable plant and the receiving port on the 1000BASE-ZX module at each end of the link whenever the fiber-optic cable span is less than 15.5 miles (25 km).
Insert a 5-dB inline optical attenuator between the fiber-optic cable plant and the receiving port on the 1000BASE-ZX module at each end of the link whenever the fiber-optic cable span is equal to or greater than 15.5 miles (25 km) but less than 31 miles (50 km).

SFP Module Cabling and Connection Equipment

The following table provides cabling specifications for the SFP modules that can be installed on the 20-Port 1-GE Flex PLIM and the 42-port 1-GE SFP PLIM. Note that all SFP ports have LC-type connectors.

The minimum cable distance for the SFP-GE-S is 6.5 feet (2 m), and the minimum link distance for the SFP-GE-Z is 6.2 miles (10 km) with an 8-dB attenuator installed at each end of the link. Without attenuators, the minimum link distance for the SFP-GE-Z is 24.9 miles (40 km).

¹ A mode-conditioning patch cord is required. When using the SFP-GE-L with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord between the SFP module and the MMF cable on both the transmit and the receive ends of the link when link distances are greater than 984 ft (300 m). We do not recommend using the SFP-GE-L and MMF with no patch cord for very short link distance (tens of meters). The result could be an elevated bit error rate (BER).

Note

The 1000BASE-ZX SFP modules provide an optical power budget of 21.5 dB. You should measure your cable plant with an optical loss test set to verify that the optical loss of the cable plant (including connectors and splices) is less than or equal to 21.5 dB. The optical loss measurement must be performed with a 1550-nm light source.

Installing and Removing SFP Modules

Before you remove or install an SFP module, read the installation information in this section and the safety information in the Laser Safety section.

Caution

Protect the SFP modules by inserting clean dust covers into them after the cables are removed. Be sure to clean the optic surfaces of the fiber cables before you plug them back into the optical ports of another module. Avoid getting dust and other contaminants into the optical ports of your SFP modules, because the optics do not work correctly when obstructed with dust.

Caution

It is strongly recommended that you do not install or remove the SFP module with fiber-optic cables attached to it because of the potential to damage the cable, the cable connector, or the optical interfaces in the module. Disconnect all cables before removing or installing the SFP module.Removing and inserting an module can shorten its useful life, so you should not remove and insert modules any more often than is absolutely necessary.

SFP modules use one of four different latching devices to install and remove the module from a port. The four types of SFP module latching devices are described in the following sections:

Note

When installing the SFP module, you should hear a click as the triangular pin on the bottom of the module snaps into the hole in the receptacle, indicating that the module is correctly seated and secured in the receptacle. Verify that the modules are completely seated and secured in their assigned receptacles on the line card by firmly pushing on each SFP module.

Bail Clasp SFP Module

The bail clasp SFP module has a clasp that you use to remove or install the module (see the following figure).

Installing a Bail Clasp SFP Module

To install this type of SFP module, follow these steps:

SUMMARY STEPS

Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.

Oversubscription of 10-GE Ports

Processing on the 10-GE PLIM is performed by two PLIM hardware controllers, each of which can process up to 24 Gbps of traffic. Ports 0 to 3 are associated with one PLIM hardware controller, while ports 4 to 7 are associated with the second PLIM hardware controller. In addition, the PLIM ports are serviced by two MSC hardware controllers, the switching capacity of which is approximately 62 Mpps (million packets per second) each. Each MSC hardware controller is statically assigned to four of the eight ports.

Because of this PLIM design, the placement of the optics modules in the PLIM can greatly affect whether or not oversubscription occurs. For example, if modules are installed in ports 0 and 1, each interface has 10 Gbps of throughput. Adding another module in port 2 causes oversubscription on all interfaces (0, 1, and 2).

If your configuration cannot support oversubscription, use the following guidelines to determine the PLIM ports in which to install optics modules:

Do not install more than four optics modules in each PLIM.
Use the following port arrangements to provide optimal performance for up to four 10-GE interfaces in a 10-GE PLIM:


	Port Numbers
Option 1	0	2	5	7
Option 2	4	4	4	6

If your configuration can support oversubscription and you want to install more than four optics modules in a PLIM, we recommend that you install additional modules in empty ports, alternating between upper and lower ports and odd and even ports. For example, if you install a fifth optics module in an odd port in the upper set of ports (0 to 3), be sure to install the next module in an even port in the lower set of ports (4 to 7), and so on.

40-Port 10-GE PLIM with SFP+ Optics Modules

Note

In the enhanced chassis, all 40 ports of this PLIM can be used. In the legacy chassis, this PLIM is operated in 200G mode as a 20-port 10-GE SFP+ PLIM. In this case, only the 20 ports on the right are enabled.

The 40-port 10-GE SFP+ PLIM supports from one to forty pluggable SFP+ optics modules.

Note

For more information about SFP+ optics modules, see SFP+ Module Connections and SFP+ Module Cabling and Connection Equipment.

Ports and LEDs

The 40-port 10-GE SFP+ PLIM has:

Forty ports that accept SFP+ optics modules
Status LED for the PLIM

Note

For this PLIM, a time interval of three seconds is required after removing, and before re-inserting the SFP+ optics modules.

The following figure shows the front panel of the 40-Port 10-GE SFP+ PLIMs.

Figure 24. 40-Port 10-GE SFP+ PLIM front panel


1	Port LED (one per port)	2	Status LED

The 40-Port 10-GE PLIM comprises two sets of twenty ports, each of which are connected to a dedicated Network Processor. When operated in the legacy chassis, the PLIM operates in 200G mode, in which the top set of ports and their Network Processor are deactivated due to thermal constraints. In 200G mode, the port numbering will be different than 400G mode and will start with 0 for the port that is labeled 20 in 400G mode. The faceplate labels therefore include two port numbers for the ports that are active in 200G Mode, as shown in the following figure.

Figure 25. Half of the Front Panel, Showing Two Sets of Port Numbers

In the enhanced chassis, the 40-Port 10-GE PLIM may optionally operate in Green mode, in which twenty of the ports are deactivated (using the CLI) to save power. In Green mode, the port numbering follows the 400G mode model, which results in only ports 20-39 being active. Ports 0-19 will not be visible in the CLI when the card is in Green mode. Therefore, the port numbers for ports used in Green mode will not change when the card is converted to 400G mode.

In addition to 10-GE modules, the 10-GE PLIM supports from one to four pluggable dense wavelength-division multiplexing (DWDM) XENPAK optics modules, each providing full-duplex long-wavelength DWDM optics with SC fiber-optic interfaces. See the 8-Port 10-GE PLIM with XENPAK Optics Modules section for general information about the PLIM.

When using DWDM optics modules on your 10-GE PLIM, an empty slot must exist next to each installed DWDM module to provide optimal cooling for the DWDM optics. For this reason, you can install up to four DWDM XENPAK modules in the 10-GE PLIM. Given this restriction and to optimize the PLIM for oversubscription, you should use port positions 0, 2, 5, and 7.

Caution

One to four DWDM XENPAK modules can be installed. If one DWDM XENPAK module is installed, a maximum of four XENPAK modules can be installed in the PLIM.

The following table lists the part numbers and frequencies of the DWDM XENPAK optics modules that are compatible with the 10-GE PLIM.

XFP Optics Power Management

The 20- and 14-port XFP PLIMs have a fixed power budget for the pluggable XFP optics:

The 20-port 10-GE XFP PLIM has a power budget of 30 watts. It can have all 20 ports filled with XFP10GLR-192SR-L V01 (10KM -> 1.5W) XFPs. If you use optics other than SR, such as XFP10GER-192IR-L V01 (40KM -> 2.5W) XFPs you must be careful not to exceed the power budget, which may result in some ports remaining unpowered. Also, unsupported optics will not power up. Cisco IOS XR software enables the ports in a sequence that allows the configuration to remain within the optics power budget.
The 14-port 10-GE XFP PLIM has a power budget of 30 watts. You can have all 14 ports filled with a combination of SR (1.5W) 10km XFPs and LR (2.5W) 40km XFPs. If you use optics other than SR or LR, you must be careful not to exceed the power budget, which may result in some ports remaining unpowered. Cisco IOS XR software enables the ports in a sequence that allows the configuration to remain within the optics power budget.
For more details on how the software controls PLIM power consumption, see Cisco IOS XR Interface and Hardware Component Command Reference for the Cisco CRS Router .

The XFP pluggable optics for the 20- and 14-port XFP PLIMs have different power consumptions based on their reach and type. The number of XFPs which will power up in a PLIM depends on their aggregate power consumption within the allocated power budget.

During XFP insertion, the power is allotted to the optics based on the insertion order of the XFPs. On boot up and reload, priority is re-assigned to the lower numbered ports.

The recommended insertion sequence is to alternate between inserting XFPs in lowest numbered ports for each interface device driver ASIC to avoid oversubscription. The insertion order for a 20 Port PLIM would be “0,10,1,11,2,12,...9,19.” For a 14 Port PLIM, insertion order would be “0,7,1,8,...6,13.”

If the PLIM power budget is exceeded, a console log message is displayed informing the user the power budget has been exceeded and to remove the XFP:


plim_[x]ge: %L2-PLIM-6-NO_POWER_XFP : Port <port number>, Not enough power available 
to power XFP, powering off

Any unpowered XFPs should be removed to ensure that the same XFPs that were powered before a reload are the same XFPs that are powered after a reload. Removing the unpowered XFPs prevents the powered down XFPs being given priority after the reload.

A show command is provided to indicate how much of the XFP power budget is currently used and how much power an XFP is consuming:

SFP+ Module Connections

The enhanced small form-factor pluggable (SFP+) module is an enhanced version of the SFP module, supporting data rates up to 10 Gbps. The SFP+ module is a hot-swappable input/output (I/O) device that plugs into an Ethernet SFP+ port on the 40-Port 10-GE PLIM. It has optical interoperability with 10GBASE XENPAK, 10GBASE X2, and 10GBASE XFP interfaces on the same link.

The 40-Port 10-GE PLIM accepts only the SFP+ modules listed as supported in this document. An SFP+ module check is run every time an SFP+ is inserted, and only SFP+ modules that pass this check can be used by the 40-port 10-GE PLIM.

SFP+ modules exist for technologies other than GE and for products other than the 40-Port 10-GE PLIM. However, the information in this document pertains only to SFP+ modules that plug into the 40-Port 10-GE PLIM ports.

The SFP+ module has a receiver port (RX) and a transmitter port (TX) that compose one optical interface.

Cabling and Specifications for 10-GE PLIMs

The following sections provide information about specifications and cabling for 10-GE Ethernet PLIMs:

Specifications for 10-GE XENPAK Interfaces

The 10-GE XENPAK optics modules use single-mode fiber-optics with SC connectors. The maximum distance for single-mode installations is determined by the amount of light loss in the fiber path. If your environment requires the light to travel close to the typical maximum distance (as listed in the following table), you should use an optical time domain reflectometer (OTDR) to measure the power loss.

Two types of 10-GE XENPAK interfaces are available: long wavelength, 1310 nanometers (nm), and extra-long wavelength, 1550 nm.

The following table lists the specifications for the 10-GE XENPAK interfaces. The actual distance in any given case depends on the quality of the fiber connected to the transceiver.

Note

Requires a 5 dB, 1550 nm fixed loss attenuator for distances less than 20 km.

Note

Links longer than 30 km are considered engineered links meaning that, for distances up to 30 km, no special link design rules need to be considered. Link distances beyond 30 km require that you verify the cable characteristics; in particular, you should verify the cable's loss value.

Specifications for 10-GE DWDM XENPAK Interfaces

The 10-GE DWDM XENPAK optics modules use single-mode fiber-optics with SC connectors. When the input power is more than the maximum receive power, you need an attenuator installed in the RX port to bring the optical power to the receiver to the correct range.

The 10-GE DWDM XENPAK interfaces are long-wavelength, 1310 nanometers (nm).

About Fiber-Optic Interface Cables

The Ethernet PLIMs use single-mode fiber-optic interface cables to connect to another Ethernet interface, router, or switch. The 10-GE PLIM with 10-GE XENPAK modules and 10-GE DWDM XENPAK modules use cables with SC connectors; the 10-GE WDMPHY PLIM uses cables with LC connectors.

Note

Fiber-optic cables are not available from Cisco Systems. They can be purchased from cable vendors.

Single-mode cables are generally yellow in color. You can use two cables with simplex connectors or one cable with dual, keyed connectors.

Warning

Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures. Statement 125

Step 5

Repeat these steps until all cabling is completed.

Note

The fiber-optic connectors must be free of dust, oil, or other contaminants. Carefully clean the fiber- optic connectors using an alcohol wipe or other suitable cleanser.

Cleaning Fiber-Optic Connectors

It is important to inspect and clean fiber-optic components before making a fiber-optic connection (for example, plugging a fiber-optic connector into a fiber-optic receptacle). Any contamination in the fiber connection can cause the optic component or the whole system to fail. Even microscopic dust particles, oil from human hands, film residues (condensed from vapors in the air), and powdery coatings (left after water or other solvents evaporate) can cause a variety of problems for optical connections.

Caution

With the high-powered lasers now in use, any contaminant can be burned into the fiber end face if it blocks the core while the laser is turned on. This burning may damage the optical surface enough that it cannot be cleaned.

For instructions on how to clean fiber-optic components, see:

http://www.cisco.com/warp/public/127/cleanfiber2.html

Always follow the fiber-optic cleaning procedures carefully. The goal is to eliminate any dust or contamination and provide a clean environment for the fiber-optic connection. Inspection, cleaning, and reinspection are critical steps that must be performed before making any fiber-optic connection.

How to Remove or Install a XENPAK Optics Module

The 10-GE XENPAK PLIMs support the DWDM XENPAK optics modules listed in PLIM Descriptions and Software and Hardware Compatibility. These optics modules are installed in ports on the PLIM and provide the optical interface connectors for the PLIM.

Note

XENPAK optics modules are keyed so that they cannot be inserted incorrectly. The PLIM automatically shuts down any optics module that is not a valid type.

Oversubscription of 40-GE Ports

Processing on the 4-port 40-GE OTU3 CFP PLIM is performed by two PLIM hardware controllers, each of which can process up to 80 Gbps of traffic. Ports 0 and 1 are associated with one PLIM hardware controller, while ports 2 and 3 are associated with the second PLIM hardware controller. In addition, the PLIM ports are serviced by line card hardware controllers that have a total switching capacity of 140 Gbps.

Because of this PLIM design, maximum throughput on the 4-port 40-GE OTU3 CFP PLIM is limited to 140 Gbps evenly distributed across the four ports. A second limitation exists, this time at the individual PLIM hardware controller level. For certain packet sizes, the effective bandwidth of the PLIM hardware controller can drop to as low as 73 Gbps (maximum 80 Gbps), which is distributed evenly to it's 2 connected ports (36.5 Gbps per port). Effective bandwidth of the PLIM hardware controller usually drops below 80Gbps at smaller packet sizes (traffic streams that contain a relatively high proportion of packets sized below 128 bytes).

40-GE Ethernet CFP Transceiver Module

The 40-GE CFP transceiver module is a hot-swappable I/O device that plugs into 40-GE ports. The CFP transceiver module connects the electrical circuitry of the system with the optical network.

Caution

If no CFP optics module is to be installed in a port, the open port must be covered with a CFP-COVER (shipped with the card). The CFP-COVER is required under this condition to preserve the integrity of the card and is required for EMC and Safety compliance and proper cooling in the chassis.

Note

Review the safety information and guidelines before installing or removing a CFP transceiver module. See How to Remove or Install a PLIM.

Note

The CFP may also be a flat top. See CFP Transceiver Module.

1-Port 100-GE PLIM with IP over DWDM

The 1-port 100-GE DWDM PLIM supports the IP over DWDM optics module. The 1-port 100-GE IP over DWDM PLIM is a thermally-sensitive PLIM. When used at high altitudes, it should be placed in the lower card cage.

Thermal Restrictions

Note

The following restrictions apply only to the legacy 16-slot chassis.

Cisco CRS thermally-sensitive PLIMs are subject to slot placement restrictions on the legacy 16-slot chassis. The following error message appears if these restrictions are not followed:

PLATFORM-SHELFMGRV2-4-AVOID_THERMALLY_SENSITIVE_PLIM_IN_UPPER_SLOT

The thermally-sensitive PLIM limitation is due to the possibility of some components exceeding their rated temperature tolerance when the system is run at 50C at elevations of 1800 meters or higher. If the high temperature condition occurs, the environmental monitoring software will shut down the thermally-sensitive PLIM when its temperature reaches configured thresholds. Therefore, this restriction applies only to routers operating at these high elevations and may be ignored otherwise.

Ports and LEDs

The 1-port 100-GE IP over DWDM PLIM has:

One port that accepts a DWDM optics module that is not pluggable
Status LED for the PLIM
One LED indicator for the single port

Cisco qualifies the optics that are approved for use with its PLIMs.

The following figure shows the front panel of the 1-port 100-GE IP over DWDM PLIMs.

4-Port 100-GE PLIM with CPAK Optics Module

Note

In the enhanced chassis, all 4 ports of this PLIM can be used. In the legacy chassis, this PLIM is operated in 200G mode as a 2-port 100-GE CPAK PLIM. In this case, only the lower 2 ports are enabled.

The 4-port 100-GE CPAK PLIM supports the CPAK optics module.

Ports and LEDs

The 4-port 100-GE CPAK PLIM has:

Four ports that accept CPAK optics modules

One LED indicator for the single port

Cisco qualifies the optics that are approved for use with its PLIMs.

The following figure shows the front panel of the 4-port 100-GE CPAK PLIMs.

Figure 44. 4-Port 100-GE CPAK PLIM front panel


1	Port LED	2	Status LED

The 4-Port 100-GE PLIM comprises two sets of two ports, each of which are connected to a dedicated Network Processor. When operated in the legacy chassis, the PLIM operates in 200G mode, in which the top set of ports and their Network Processor are deactivated due to thermal constraints. In 200G mode, the port numbering will be different than 400G mode and will start with 0 for the port that is labeled 2 in 400G mode. The faceplate labels therefore include two port numbers for the ports that are active in 200G Mode, as shown in the following figure.

Figure 45. Half of the Front Panel, Showing Two Sets of Port Numbers

In the enhanced chassis, the 4-Port 10-GE PLIM may optionally operate in Green mode, in which two of the ports are deactivated (using the CLI) to save power. In Green mode, the port numbering follows the 400G mode model, which results in only ports 1-2 being active. Ports 0-1 will not be visible in the CLI when the card is in Green mode. Therefore, the port numbers for ports used in Green mode will not change when the card is converted to 400G mode.

The following table describes the PLIM LEDs for the 4-port 100-GE CPAK PLIM.

Figure 46. 2-port 100-GE and 5-port 40-GE QSFP+ Combination PLIM Front Panel


1	Port LED	2	Status LED

The 2-port 100-GE and 5-port 40-GE QSFP+ combination PLIM comprises two sets of two ports, each of which are connected to a dedicated Network Processor. When operated in the legacy chassis, the PLIM operates in 200G mode, in which the two 100G CPAK ports are deactivated and only the 40G QSFP+ ports are activated. When operated in the enhanced chassis, the PLIM operates in 400G mode, in which all ports (2x100GE ports and 5x40GE ports) are activated. Switching from 400G mode to 200G mode in the enhanced chassis is not supported.

Note

For 40-Gbps to 10-Gbps breakout options, the 40-GE ports only support the SR-4 breakout cable that has a cylindrical splitter.

In 200G mode, the port numbering is different than 400G mode and starts with 0 for the port that is labeled 2 in 400G mode. The faceplate labels therefore include two port numbers for the ports that are active in 200G Mode, as shown in the following figure.

Step 6

Continue sliding the card into the card cage slot until the openings on the card ejector cams engage the tabs on each side of the card cage slot.

Note

Guide pins located on the midplane connector make initial contact with the card connector as you slide a card into its slot. After the guide pins make contact, continue pushing on the card carrier until the card ejector levers begin pivoting forward toward the handle in the card carrier.

Step 7

To seat the card in the midplane connector, grasp both card ejector levers and pivot them inward toward the handle in the card carrier until they are flush against the front edge of the card carrier.

Step 8

Engage both captive screws on the PLIM, and then tighten the screws.

Caution

Be sure to engage both captive screws on the PLIM before you begin to tighten the screws; otherwise, the PLIM might not seat properly.

Caution

To ensure adequate space for additional PLIMs, always tighten the captive installation screws on each newly installed PLIM before you insert another PLIM. These screws also prevent accidental removal and provide proper grounding and EMI shielding for the system.

Step 9

For the 10-GE PLIM, install the XENPAK or XFP optics modules. See the How to Remove or Install a PLIM Cable Management Bracket section or How to Remove or Install an XFP Module section.

Step 10

If this PLIM is new, install the PLIM cable management bracket. See the Removing a PLIM Cable Management Bracket section.

Step 11

Install the interface cables. We recommend that you clean the fiber-optic connections before attaching the cables. For cleaning instructions, see: http://www.cisco.com/warp/public/127/cleanfiber2.html .

Step 12

If this PLIM is new, configure it for operation. For instructions, see Cisco IOS XR Interface and Hardware Component Configuration Guide and Cisco IOS XR Interface and Hardware Component Command Reference , available at:

http://www.cisco.com/univercd/cc/td/doc/product/ioxsoft/iox33/index.html

Warning

Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures. Statement 125

Verifying the Installation of a PLIM

This section describes how to verify that a PLIM has been properly installed. See the figure showing the front panel of your PLIM for the locations of the port and Status LEDs on the front panel of the PLIM (see 20-Port 1-GE Flex PLIM Front Panel for the 20-port 1-GE PLIM with SFP optics modules or see 14-Port 10-GE XFP PLIM front panel for the 14-port 10-GE XFP PLIM).

If a PLIM fails to operate or power up on installation:

Make sure that the PLIM is seated firmly in the line card chassis slot. One easy way to verify physical installation is to see whether the front faceplate of the PLIM is even with the fronts of the other PLIMs installed in the card cage.
Make sure that the corresponding MSC is installed and operating correctly.
Check whether the ejector levers are latched and that the captive screws are fastened properly. If you are uncertain, unlatch the levers, loosen the screws, and attempt to reseat the PLIM.
Determine whether there are any active alarms by looking at the alarm LEDs on the alarm module (16-slot chassis) or the route processor (8-slot or 4-slot chassis). See Cisco CRS-1 Carrier Routing System Line Card Chassis System Description for more information about alarms.
Examine the power shelves (16-slot chassis) or power distribution units (PDUs) (8-slot and 4-slot chassis) to see whether the chassis, as a whole, is receiving power.

Use the LEDs on the PLIM to verify the correct installation and operation of the card.

How to Remove or Install a PLIM Cable Management Bracket

Cisco CRS chassis include a cable management system that organizes the interface cables entering and exiting the router, keeping them out of the way and free of sharp bends.

Caution

Excessive bending of interface cables can damage the cables.

The cable management system consists of two separate components:

The line card chassis arrives preinstalled with a horizontal cable management bracket on the front of the chassis and an optional horizontal cable management bracket available for the rear of the chassis. The cable management system organizes the interface cables entering and exiting the different cards, keeping them out of the way and free of sharp bends. See the appropriate Cisco CRS installation guide for more information on the chassis cable management bracket.
A cable management bracket that attaches to a PLIM.

This section describes how to remove and install the two types of PLIM cable management bracket. The following shows the PLIM cable management bracket. PLIM Articulated Cable Management Bracket shows the articulated PLIM cable management bracket, designed for installing on the 20-port 1-GE FLEX PLIM and the 42-port 1-GE XFP PLIM.

Figure 53. PLIM Cable Management Bracket

Figure 54. PLIM Articulated Cable Management Bracket

Note the following:

The front leg of the articulated PLIM cable management bracket is light gray. The articulated bracket can be moved for ease of cabling or uncabling. Always connect your interface cables starting with the interface at the top of the PLIM and always disconnect your interface cables starting with the interface at the bottom of the PLIM.
For details about replacing a SFP from a line card that uses an articulated bracket, see Replacing a SFP on a Line Card that Uses an Articulated Bracket.
You do not have to remove the interface cables from the PLIM cable management bracket. If you are replacing the PLIM, you can remove the cable management bracket from the PLIM. After you install a new PLIM, you can attach the cable management bracket to the new PLIM and reattach the interface cables. See the Removing and Installing Fiber-Optic Interface Cables section.

Caution

Do not use the cable management bracket alone as a handle to pull out or push in the PLIM. One hand must be under the PLIM to support its weight when carrying the PLIM. The cable management bracket is designed to hold the interface cables and may break if you use the bracket to push, pull, or carry the PLIM after it is removed from the router.

Before You Remove or Install a Transceiver Module

Review the following sections carefully before you remove or install any type of transceiver module:

Safety Guidelines

Before you perform any procedure in this document, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment. See the Laser Safety section.

The following guidelines are for your safety and to protect equipment. The guidelines do not include all hazards. Be alert.

Note

Review the safety warnings listed in Regulatory Compliance and Safety Information for the Cisco CRS-1 Carrier Routing System before installing, configuring, or troubleshooting any installed card.

Never attempt to lift an object that might be too heavy for you to lift by yourself.
Keep the work area clear and dust free during and after installation. Do not allow dirt or debris to enter into any laser-based components.
Keep tools and router components away from walk areas.
Do not wear loose clothing, jewelry, and other items that could get caught in the router while working with OIMs, SFCs, and their associated components.
Use Cisco equipment in accordance with its specifications and product-usage instructions.
Do not work alone if potentially hazardous conditions exist.
Make sure your installation follows national and local electrical codes: in the United States, National Fire Protection Association (NFPA) 70, United States National Electrical Code; in Canada, Canadian Electrical Code, part I, CSA C22.1; in other countries, International Electrotechnical Commission (IEC) 60364, part 1 through part 7.
Connect only a DC power source that follows the safety extra-low voltage (SELV) requirements in UL/CSA/IEC/EN 60950-1 and AS/NZS 60590 to the FCC DC-input power system.
Make sure that you have a readily accessible two-poled disconnect device incorporated in the fixed wiring of an LCC configured with the DC-input power system.
The LCC requires short-circuit (overcurrent) protection to be provided as part of the building installation.

Preventing Electrostatic Discharge

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. We recommend that you use an ESD-preventive strap whenever you handle network equipment or components.

Following are guidelines for preventing ESD damage:

Always use an ESD-preventive wrist or ankle strap, and ensure that it makes good skin contact. Connect the equipment end of the connection cord to an ESD connection socket on the router or a bare metal surface on the chassis.
Handle a card by its ejector levers, when applicable, or metal carrier only; avoid touching the board or connector pins.
Place a removed card component side up on an antistatic surface or in a static-shielding bag. If you plan to return the component to the factory, immediately place it in a static-shielding bag.
Avoid contact between the card and clothing. The wrist strap protects the board only from ESD voltage on the body; ESD voltage on clothing can still cause damage.

Guidelines for Card Installation and Removal

Guidelines for card installation and removal include the following:

Online insertion and removal (OIR) is supported, enabling you to remove and install cards while the router is running. OIR is seamless to users on the network, maintains all routing information, and ensures session preservation. Notifying the software or resetting the power is not required. However, you have the option of using the shutdown command before removing a card.
Each PLIM and its corresponding MSC function as a pair. If either card is removed, the other card is essentially powered down (although the router can still identify and inventory the cards).
PLIMs in the line card chassis are attached to the chassis by way of a pair of ejector levers and captive screws. The two ejector levers are used to release the PLIM from its midplane connector. The ejector levers and captive screws are located on the upper and lower ends of the faceplate of the card (see the following figure).

Figure 58. Ejector Levers and Captive Screws


1	Captive screw	2	Ejector lever

Caution

When you remove a PLIM, always use the ejector levers to ensure that the connector pins disconnect from the midplane in the sequence expected by the router.The router can indicate a hardware failure if you do not follow proper procedures. Remove or install only one card at a time. Wait at least 15 seconds before removing or installing another card.

About PLIM Impedance Carriers

A PLIM impedance carrier must be installed in each empty PLIM slot in the Cisco CRS chassis (see the following figure). The impedance carrier preserves the integrity of the chassis and is required for EMI compliance and proper cooling in the chassis.

Regulatory, Compliance, and Safety Information

This section contains information on laser safety.

For other regulatory, compliance, and safety information, including translated safety warnings, see the Regulatory Compliance and Safety Information for the Cisco CRS-1 Carrier Routing System publication.

Laser Safety

Do not stare into operational transceiver module ports. The following laser warning applies:

Warning

Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 70
