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 router 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 router 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

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.
Note 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 the
IEEE 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
Table 7 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).

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:
•Bale Clasp SFP Module
•Mylar Tab SFP Module
•Actuator Button SFP Module
•Slide Tab SFP Module
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.
Bale Clasp SFP Module
The bale clasp SFP module has a clasp that you use to remove or install the module (see Figure 4).

Replacing a SFP on a Line Card that Uses an Articulated Bracket
To replace a failed, defective, or retired SFP from a line card that is currently in service, and using an articulated cable management bracket, proceed as follows:
Step 1 For a line card with multiple articulated brackets, select the fibers to be removed from the bracket with the SFP to be removed.
For a line card with a single articulated bracket, begin with Step 2.
Step 2 Undo and remove the Velcro from the articulated bracket to release the fibers.
Step 3 From the physical location of the SFP to be removed, determine which end of the articulated bracket will be unscrewed:
•For the upper half of the line card, remove the top screw.
•For the lower half of the line card, remove the lower screw.
•If there is any interference with another installed bracket, choose the other screw location.
Step 4 Pivot the articulated bracket up or down, depending on which screw was removed.
Step 5 Label and disconnect the fibers from the port and put them aside.
Step 6 Remove the SFP.
Step 7 Replace with the new SFP (or a dust cap if the port is not going to be reused).
Step 8 Re-install the fibers that were removed in Step 5 per the labels.
Step 9 Pivot the articulated bracket back into position and secure.
Step 10 Re-dress and secure the fibers to the articulated bracket with Velcro.

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:
| |

0
|

|

|

|
Option 2
|

|

|
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.

10-GE PLIM with DWDM XENPAK Modules
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.
Table 16 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:

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 Table 20), 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.
Table 20 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.

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).
Table 21 lists the specifications of the 10-GE DWDM XENPAK interfaces.

Cabling a 10-GE XFP Transceiver
Use this procedure to cable 10-GE XFP transceivers:
Note Before removing the dust plugs and making any optical connections, follow these guidelines:
•Always keep the protective dust plugs on the unplugged fiber-optic cable connectors and the transceiver optical bores until you are ready to make a connection.
•Always inspect and clean the LC connector end faces just before making any connections. For more information on cleaning fiber-optic connections, see the "How to Remove or Install a PLIM Cable Management Bracket," page 69.
•Always grasp the LC connector housing to plug or unplug a fiber-optic cable.
Step 1 Remove the dust plugs from the optical network interface cable LC connectors (see Figure 34). Save the dust plugs for future use.
Step 2 Inspect and clean the LC connector's fiber-optic end faces.
Step 3 Remove the dust plugs from the XFP transceiver module optical bores.
Step 4 Immediately attach the network interface cable LC connectors to the XFP transceiver module. (See Figure 25 for an illustration of cabling the XFP transceiver module.)
Figure 25 Cabling a10-GE XFP Transceiver Module
About Fiber-Optic Interface Cables
Do we need to add a pic of the SR4 cable/connector here? Email out to verify.
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 (see Figure 26 and Figure 27); the 10-GE WDMPHY PLIM uses cables with LC connectors (see Figure 28 and Figure 29).
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.

Removing and Installing Fiber-Optic Interface Cables
This section contains information on removing and installing fiber-optic interface cables to connect your router to another router or switch.
Required Tools and Equipment
You need the following tools and part to remove or install interface cables:
•ESD-preventive wrist strap
•Medium (Number 2) Phillips screwdriver
•Interface cables
Removing Fiber-Optic Interface Cables
To remove interface cables, see Figure 30 and follow these steps:
Step 1 Attach an ESD-preventive wrist or ankle strap to your wrist and follow its instructions for use.
Step 2 Press on the spring-action disconnect latch to disconnect the interface cable connectors from the PLIM interface ports. When the cable is removed from the 10-GE PLIM, the spring-loaded cover plate folds over to cover the interface port. Note that the other PLIMs do not have spring-loaded cover plates that cover their interface ports.
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
Note 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 "How to Remove or Install a PLIM Cable Management Bracket" section.

Note Connectors on the fiber-optic cables must be free of dust, oil, or other contaminants. Before connecting the cable to the PLIM, carefully clean the fiber-optic connectors using an alcohol wipe or other suitable cleanser. See the "How to Remove or Install a PLIM Cable Management Bracket" section for more information.
To install interface cables, follow these steps:
Step 1 For a 10-GE PLIM, open the spring-loaded plate that covers the port. Note that the other PLIMs do not have spring-loaded cover plates that cover their interface ports. Remove the connector dust cover if one is present.
Step 2 Align the connector end of the cable to the appropriate port. Observe the receive (RX) and transmit (TX) cable relationship on the cables, as shown in Figure 31.
Step 3 Attach a fiber cable between the port in the PLIM and the device to which the PLIM is connected.
Step 4 Insert the fiber cable connector until it clicks and locks into place.
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 Table 16. 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.
Figure 32 shows a DWDM XENPAK optics module.

This section contains the following procedures:
•Removing a XENPAK Optics Module
•Installing a XENPAK Optics Module
Prerequisites
To stay within the maximum received power specification on the RX side of the XENPAK module, an attenuator might be required. To determine if an attenuator is needed for the XENPAK module, see "Specifications for 10-GE XENPAK Interfaces" section.
Required Tools and Equipment
Have the following equipment available before you install or remove a XENPAK module:
•Dust plugs to keep unused ports clean
•Antistatic surface on which to place the module
•Attenuator, if one is determined to be needed in the prerequisites
Removing a XENPAK Optics Module
This section describes how to remove a XENPAK optics module from the PLIM.
Step 1 Use the shutdown command before you remove a XENPAK optics module.
Caution It is important to use the
shutdown command to prevent anomalies from occurring when you install a new XENPAK module.
Step 2 Disconnect any network interface cables that are attached to the optics module, and install the optical bore dust plugs.
Step 3 Loosen the two captive screws securing the optics module in the PLIM.
Step 4 Carefully pull the two captive screws to disconnect the optics module from the connector within the PLIM port.
Step 5 Grasp the edges of the optics module, and carefully slide it from the PLIM port.
Step 6 Place the optics module on an antistatic surface.
Installing a XENPAK Optics Module
This section describes how to install a XENPAK optics module in the PLIM.
Step 1 Remove the optics module from its protective packaging.
Step 2 Align the optics module with the PLIM port, and slide the module into the port until the back of the optics module faceplate is flush with the PLIM faceplate. This step ensures proper connection between the PLIM connector and the optics module connector. XENPAK modules are keyed so that they cannot be inserted incorrectly.
Step 3 Secure the optics module by tightening the two captive installation screws. Do not cross-thread or overtighten the captive screws.
Note Make sure that the optics module is fully inserted into the PLIM port and that the captive screws are fully tightened before attaching the fiber-optic interface cable to the optics module connector.
Step 4 Remove the optical bore dust plugs from the optics module, and attach the network interface cable to the optics module connector.
How to Remove or Install an XFP Module
The 10-GE XFP PLIMs support the XFP optics modules listed in Table 18. The 10-GE XFP transceiver module is a hot-swappable I/O device that plugs into 10-GE ports (see Figure 33). The XFP transceiver module connects the electrical circuitry of the system with the optical network.
Note The dual LC connector on the XFP transceiver modules supports network interface cables with either Physical Contact (PC) or Ultra-Physical Contact (UPC) polished face types. The dual LC connector on the XFP transceiver modules does not support network interface cables with an Angle Polished Connector (APC) polished face type.
Caution We strongly recommended that you do not install or remove the XFP module with fiber-optic cables attached to it because of the potential of damaging the cable, the cable connector, or the optical interfaces in the XFP module. Disconnect all cables before removing or installing an XFP module.
Removing and inserting an XFP module can shorten its useful life, so you should not remove and insert XFP modules more often than what is absolutely necessary.

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.

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 IPoDWDM PLIM and 4-port 40-GE OTU3 CFP PLIM are examples of high powered PLIMs. High powered PLIMs are confined to upper slots, but are allowed in lower slots only if another identical PLIM is installed directly above. This restriction applies solely to the standard 16-slot chassis; the 4-slot and 8-slot chassis are excepted.
Power Management Restrictions
If you want to fill your chassis with these PLIMs, the following power management restrictions apply:
•4-slot chassis - 1 slot must be left void (meaning that a PLIM blank must be inserted)
•8-slot chassis - 2 slots must be left void (one in zone 1 and one in zone 3)
•16-slot chassis - 4 slots must be left void (one each in zones 1, 3, 4 and 6)
•8-slot and 16-slot enhanced chassis - no restrictions
Ports and LEDs
The 1-port 100-GE IPoDWDM 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.

How to Remove or Install a PLIM
A PLIM provides the data interfaces for the routing system and mates with its associated MSC through the chassis midplane.
This section contains the following procedures:
•Removing a PLIM
•Installing a PLIM
Removing a PLIM
This section describes how to remove a PLIM from the line card chassis.
Caution The system may indicate a hardware failure if you do not follow proper procedures. Remove or install only one PLIM at a time. Allow at least 15 seconds for the system to complete the preceding tasks before removing or installing another PLIM.
Required Tools and Equipment
You need the following tools to remove a PLIM:
•ESD-preventive wrist strap
•Medium (Number 2) Phillips screwdriver
To remove a PLIM, see Figure 42 and follow these steps:
Step 1 Attach an ESD-preventive wrist strap and follow its instructions for use.
Step 2 Identify the card to be replaced, and unplug the interface cables connected to the card. Be sure to note the current connections of the cables to the ports on the PLIM.
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 3 For the 10-GE PLIMs, remove the XENPAK or XFP optics modules from the card and set them aside. See the "How to Remove or Install a PLIM Cable Management Bracket" section or "How to Remove or Install an XFP Module" section.
Step 4 Loosen the two captive screws holding the card in place.
Step 5 Grasp the two card ejector levers and simultaneously pivot both ejector levers 90 degrees (70 degrees for a newer PLIM) away from the front edge of the card carrier to unseat the card from the backplane (see Figure 42).
Step 6 Grasp the cable management bracket and gently pull the PLIM halfway from the slot.
Step 7 Slide the card from the slot, using one hand under the PLIM to support and guide it (see Figure 42). Avoid touching the PLIM printed circuit board, components, or any connector pins. Do not lift cards by the cable management bracket; lift them from the bottom.
Step 8 Place the PLIM directly into an antistatic sack or other ESD-preventive container.
Step 9 Insert another PLIM or an impedance carrier into the empty card slot.

Installing a PLIM
This section describes how to install a PLIM in the line card chassis. You can install a PLIM in any slot not occupied by a route processor (RP) card (or a fan controller card, 16-slot chassis only). If you install a new MSC or PLIM, you must first remove the impedance carrier card from the available slot.
Caution The system may indicate a hardware failure if you do not follow proper procedures. Remove or install only one PLIM at a time. Allow at least 15 seconds for the system to complete the preceding tasks before removing or installing another PLIM.
Required Tools and Equipment
You need the following tools and part to install a PLIM:
•ESD-preventive wrist strap
•Medium (Number 2) Phillips screwdriver
•PLIM
Steps
To install a PLIM, see Figure 42 and follow these steps:
Step 1 Attach the ESD-preventive wrist strap and follow its instructions for use.
Step 2 Remove the PLIM from its antistatic packaging.
Step 3 Remove the PLIM impedance carrier from the slot you need to fill and set it aside.
Note Remove only one impedance carrier and install one PLIM at a time. Be sure to verify that each PLIM is fully installed and secured before installing another card.
Step 4 Grasp the cable management bracket with one hand and place your other hand under the carrier to support and guide the card into the correct slot. Slide the card halfway into the correct slot. Avoid touching the card circuitry or any connectors.
Step 5 Pivot both card ejector levers so that the openings on the card ejector cams at the top and bottom of the card pass over the tabs on each side of the card cage slot.
Caution Verify that the openings on the card ejector cams pass over the tabs; otherwise, one or both ejector levers might bind when you attempt to close the ejector levers, thereby damaging or breaking one or both ejector levers.
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 "Installing 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.htm

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 (for example, see Figure 2 for the 20-port 1-GE PLIM with SFP optics modules or see Figure 22 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. Figure 43 shows the PLIM cable management bracket. Figure 44 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 43 PLIM Cable Management Bracket
Figure 44 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.
Required Tools and Equipment
You need the following tools and part to remove or install a PLIM cable management bracket:
•ESD-preventive wrist strap
•Medium (Number 2) Phillips screwdriver
•PLIM
•PLIM cable management bracket
Removing a PLIM Cable Management Bracket
To remove a PLIM cable management bracket, follow the steps below. For an example of a fixed PLIM cable management bracket refer to Figure 45 (the 10-GE PLIM is shown in the illustration, but the installation procedure is similar for all PLIMs). For an example of an articulated PLIM cable management bracket designed for installing on the 20-port 1-GE FLEX PLIM refer to Figure 46 and for an example of an articulated PLIM cable management bracket designed for installing on the 42-port 1-GE XFP PLIM refer to Figure 47.
Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2 Note the current interface cable connections to the ports on each PLIM.
Step 3 Starting with the interface cable for the bottom port on the PLIM, disconnect the cable from the PLIM interface.
Note It is not necessary to remove the interface cables from the PLIM cable management bracket. The bracket (with attached cables) can be hooked to the chassis cable management bracket or a bracket on the chassis until a new PLIM is installed.
Step 4 Proceed upward and remove the interface from the Velcro strap on the end of the cable standoff (see callout 2 on Figure 45, Figure 46, or Figure 47). Avoid any tight twists or sharp bends in the cable.

Installing a PLIM Cable Management Bracket
To install a PLIM cable management bracket, follow these steps:
Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2 Attach the PLIM cable management bracket to the PLIM as follows:
a. Position the cable management bracket over the front of the PLIM faceplate.
Note When you are installing the articulated PLIM cable management bracket, ensure that the pin next to the captive screw goes into the proper hole before you attempt to tighten the captive screws to secure the bracket to the PLIM.
b. Insert and tighten the captive screws to secure the bracket to the PLIM.
c. Starting with the bottom port on the PLIM, connect each interface cable to the intended port.
Step 3 Carefully wrap the cables with the supplied Velcro strap (refer to callout 2 on Figure 45, Figure 46, or Figure 47). Avoid any tight twists or sharp bends in the cable.
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
•Preventing Electrostatic Discharge
•Guidelines for Card Installation and Removal
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 Figure 48).
Figure 48 Ejector Levers and Captive Screws

|
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 Figure 49). The impedance carrier preserves the integrity of the chassis and is required for EMI compliance and proper cooling in the chassis.
