Guidelines and Warnings for Card Installation and Removal
This section contains the guidelines for card installation and removal.
Caution Removing more than one card at a time can misalign the chassis and may damage the card or chassis when reinserting the cards. Remove and reinsert only one card at a time.
Online (in-service) insertion and removal (OIR) is supported, enabling you to remove and install cards while the router is operating. 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.
The different cards and PLIMs in the line card chassis are all attached to the chassis itself using a pair of ejector levers and captive screws. The two ejector levers release the card or PLIM from its midplane connector. The exact location of the ejector levers and captive screws varies slightly from card to card, but are in general in the same location: on the upper and bottom of the faceplate of the card. Figure 4-1 shows the location of the ejector levers and captive screws on an MSC.

Figure 4-2 shows how to operate the ejector levers. Be sure to operate both levers simultaneously.
Figure 4-2 Operating Ejector Levers
When shipped, every slot in the chassis contains either an impedance carrier, or is covered by a slot cover (see the "Information About Impedance Carriers and Slot Covers" section).
Note While it is not critical for you to install the cards in a certain order, following the card installation recommendations in this chapter will make your installation process easier.
Chassis Slot Numbers
Figure 4-3 and Figure 4-4 show the slot numbers for the Cisco CRS 8-slot line card chassis.
Figure 4-3 Line Card Chassis Slot Numbers—Front (PLIM) Side
Figure 4-4 Line Card Chassis Slot Numbers—Rear (MSC) Side
Recommended Order of Card Installation
Card should be installed in a particular order. We recommend the following order when removing the impedance carriers and installing the cards in the chassis (see Figure 4-3 and Figure 4-4):
1. Install the RP cards first one card at a time, the left one (slot RP0) before the right one (slot RP1). Tighten the screws only after fully inserting both RP cards.
Note It is important to engage and partially tighten all screws first, before fully tightening them with a screwdriver. This action helps ensure that all parts are aligned properly in the chassis.
2. Install the switch fabric cards one at a time in the same manner.
We recommend that you install fabric cards from left to right, starting from top to bottom, in this order:
–Slot SM0
–Slot SM1
–Slot SM2
–Slot SM3
3. For the line cards and PLIMs, you must remove one impedance carrier, install a functional board, and tighten the screw; then repeat the process until all cards and PLIMs have been installed.
Cautions and Recommendations
Caution When you remove a card, always use the ejector levers to ensure that the connector pins disconnect from the midplane in the sequence expected by the router.
Caution The router may indicate a hardware failure if you do not follow proper procedures.
Remove or install only one card at a time. Allow at least 15 seconds for the router to complete the preceding tasks before removing or installing another card.
Do not operate the Cisco CRS 8-slot line card chassis with any slots completely empty; doing so could lead to an airflow bypass condition that diverts airflow from slots containing heat-generating electronics, possibly causing thermal alarms to occur at lower-than-expected ambient temperatures.
To avoid airflow bypass, all slots should be filled with their appropriate cards or impedance carriers. If you have to replace a card, we recommend leaving the card in place in the chassis until you are ready to install the new one.
Tip To lessen the possibility of damaging the connectors on the chassis midplane, you should visually inspect the connector pins on the cards before you insert them into the chassis.
Information About Impedance Carriers and Slot Covers
When shipped, all slots in the chassis either contain impedance carriers or are covered by slot covers to help maintain chassis stiffness and ensure that the chassis is undamaged during shipment. Four different types of impedance carriers and slot covers exist for the four different sizes of slots in the chassis (see Figure 4-5, Figure 4-6, Figure 4-7, and Figure 4-8).
Figure 4-5 Switch Fabric Slot (Half Height) Slot Cover
Figure 4-6 RP Slot Impedance Carrier
Figure 4-7 PLIM Slot Impedance Carrier
Figure 4-8 MSC Slot Impedance Carrier
For further information on installing and removing the slot covers and impedance carriers, see the "Installing a Slot Cover" section, the "Removing a Slot Cover" section, the "Installing an Impedance Carrier" section, and the "Removing an Impedance Carrier" section.
Information About Distributed Route Processors and Distributed Route Processor PLIMs
The Cisco CRS Carrier Routing System provides distributed route processor (DRP) support through the installation of DRP PLIMs and DRP cards on the Cisco CRS 8-slot line card chassis (see Figure 4-9 and Figure 4-10). The installation of DRPs provides you with the ability to configure the system for logical router support and additional processor power for multichassis systems.
Figure 4-9 DRP PLIM
Figure 4-10 DRP Card
For DRP support, you must install both the DRP PLIM in a PLIM slot on the front (PLIM) side of the chassis and a DRP card in the corresponding slot on the rear (MSC) side of the chassis. The DRP PLIM and DRP cards are installed in the same manner as regular PLIMs and MSCs. See the "How to Install or Remove a Physical Layer Interface Module" section or the "How to Install or Remove an MSC, FP, or LSP" section for further information.
DRPs contain two CPU complexes, independent of each other, each with its own hard drive. In addition, the DRP provides you with two PCMCIA card slots, similar to the RP. For further information, see the "Information About Hard Drives and PCMCIA Cards" section. For installation or removal information, see the "Removing an RP PCMCIA Card" section.
Information About Small Form-Factor Pluggable (SFP) Modules
The SFP module for the line card chassis uses the bale clasp latch type.
Caution Protect the SFP modules by inserting clean dust covers into them after the cables are removed from them. Be sure to clean the optic surfaces of the fiber cables before you plug them back into the optical ports of another SFP module. Avoid getting dust and other contaminants into the optical ports of the SFP modules: The optics do not work correctly when obstructed with dust.
Note Only the 16-port OC-48c/STM-16c MSC uses SFP modules.
Information About Hard Drives and PCMCIA Cards
Optional and replaceable hard drives and PCMCIA cards are available for the DRP cards.
The hard drive is an IDE hard drive used for gathering debugging information, such as core dumps from the DRPs or MSCs. The IDE hard drive is typically powered down and activated only when there is a need to store data. The drive is not vital to a functioning chassis and is optional.
Note Core dumps are discoverable only through intervention with the chassis system software.
Physically, the DRP hard drive is a hot-pluggable PC board and sled-mounted drive with a connector interface that gets cleanly seated into a route processor card. In general, removal and replacement of this drive is not required.
The DRP cards provide two PCMCIA flash slots, each card providing up to 1 GB of flash storage. One of the PCMCIA flash subsystems is accessible externally, is removable, and allows you to transfer images and configurations by plugging in a PCMCIA flash card. The other subsystem is fixed to the DRP, not removable, and for permanent storage of configurations and images.
Information About Cable Management Brackets
The Cisco CRS 8-slot line card chassis includes a cable management system that organizes the interface cables entering and exiting the different cards, keeping them out of the way and free of sharp bends.
Caution Excessive bending of interface cables can damage the cables.
The Cisco CRS 8-slot line card chassis arrives preinstalled with a horizontal cable management bracket on the front of the chassis and an optional horizontal cable management bracket orderable for the rear of the chassis.
Figure 4-11 shows the chassis cable management bracket.
Figure 4-11 Cable Management Bracket

How to Install or Remove a Switch Fabric Card
This section contains the following procedures:
•Installing a Switch Fabric Card
•Removing a Switch Fabric Card
•Verifying the Installation of a Switch Fabric Card
Installing a Switch Fabric Card
This section describes how to install a switch fabric card in the Cisco CRS 8-slot line card chassis. For more detailed information on the switch fabric card, see Cisco CRS Series Carrier Routing System 8-Slot Line Card Chassis System Description.
The switch fabric card is used only in single-chassis systems. The switch fabric card does not contain any fiber-optic connectors because it is not connected to any other switch fabric modules (see Figure 4-17).
Figure 4-17 Switch Fabric Card
Prerequisites
Before performing this task, remove any front cover plates from the chassis, and remove any switch fabric card or switch fabric impedance cover from the slot in which you plan on installing the switch fabric card. See the "Information About Impedance Carriers and Slot Covers" section and the "Removing a Switch Fabric Card" section.
Caution Removing more than one switch fabric card at a time can misalign the chassis and may damage the card or chassis when reinserting the cards. Remove and reinsert only one card at a time.
Required Tools and Equipment
You need the following tools and part to perform this task:
•ESD-preventive wrist strap
•Large Phillips screwdriver
•Switch fabric card (Cisco Product number CRS-8-FC/S=)
Steps
To install a switch fabric card, see Figure 4-18 and follow these steps:

Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to an ESD connection socket on the rear (MSC) side or a bare metal surface on the chassis.
Step 2 Remove the switch fabric card from its antistatic packaging.
Step 3 Visually inspect the connector pins on the card before you insert it into the chassis. Do not attempt to install a card with bent pins, as this may damage the chassis midplane connectors.
Step 4 Grasp the card carrier handle with one hand and place your other hand under the carrier to support and guide it into the correct slot.
Step 5 Position the card for insertion into the card cage slot. Avoid touching the card circuitry or any connectors.
Note Alignment grooves exist on each slot in the card cage. When you install a card in the card cage, make sure that you align both edges of the card carrier in the slot grooves.
Step 6 Orient the switch fabric card so that the PCB faces left and the carrier is to the right; if the card does not slide easily into the slot, the orientation may be wrong and the misorientation rejection flange is stopping the card from going in. Reorient the switch fabric card, if necessary.
Step 7 Carefully slide the switch fabric card into the slot until the ejector levers meet the edges of the card cage, then stop when the ejector lever hooks catch the lip of the card cage. If they do not catch, try reinserting the switch fabric card until the ejector lever hooks are fully latched.
Note The insertion of the switch fabric card into the chassis may require more force than is typical of the other cards in the chassis.
Step 8 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 may bind when you attempt to close the levers, thereby damaging or breaking one or both of them.
Step 9 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 Switch fabric cards have guide pins that make initial contact with the midplane connector as you slide a card into its slot. After the guide pins make contact, continue pushing the card carrier until the card ejector levers begin pivoting forward, toward the handle in the card carrier.
Step 10 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.
Tip The flange on the front panel of the card carrier should be flush against the card cage.
Step 11 Partially tighten the two captive screws on the front panel of the card (either by hand or with the screwdriver) to make sure that they are both engaged.
Step 12 Use the screwdriver to fully tighten the captive screws to seat the card firmly in the slot.
What to Do Next
After performing this task:
•Place the impedance carrier in an antistatic bag for storage and future use.
•Replace any front cover cosmetic plates and verify that the card has been installed properly (see the "Verifying the Installation of a Switch Fabric Card" section).
•If you are performing the initial installation of the system, install the MSCs (see the "Installing an MSC, FP, or LSP" section).
Removing a Switch Fabric Card
This section describes how to remove a switch fabric card from the Cisco CRS 8-slot line card chassis. For more detailed information on the switch fabric card, see Cisco CRS Series Carrier Routing System 8-Slot Line Card Chassis System Description.
The switch fabric card is used only in single-chassis systems. The switch fabric card does not contain any fiber-optic connectors because it is not connected to any other switch fabric modules (see Figure 4-19).
Figure 4-19 Switch Fabric Card
Prerequisites
Before performing this task, remove any front cover plates.
Caution Removing more than one switch fabric card at a time can misalign the chassis and may damage the card or chassis when reinserting the cards. Remove and reinsert only one card at a time.
Required Tools and Equipment
You need the following tools to perform this task:
•ESD-preventive wrist strap
•Large Phillips screwdriver
Steps
To remove a switch fabric card, see Figure 4-20 and follow these steps:

Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to an ESD connection socket on the rear (MSC) side or a bare metal surface on the chassis.
Step 2 Identify the switch fabric card to be removed from the card cage.
Step 3 To loosen the card from the slot, turn the two captive screws on the front panel of the card counterclockwise.
Step 4 To unseat the card from the midplane connector, grasp the two card ejector levers and simultaneously pivot both ejector levers 90 degrees (70 degrees for a newer switch fabric card) away from the front edge of the card carrier.
Step 5 Touching only the metal card carrier, slide the card from the slot and place it directly into an antistatic sack or other ESD-preventive container. If you plan to return the defective card to the factory, repackage it in its original shipping container.
What to Do Next
After performing this task, replace any front cover plates.
Verifying the Installation of a Switch Fabric Card
This section describes how to verify that a switch fabric card has been properly installed. Figure 4-21 shows the switch fabric card front panel.
Figure 4-21 Switch Fabric Card Front View
Understanding the Alphanumeric LEDs
At one end of the faceplate, near an ejector lever, a switch fabric card has an alphanumeric LED display that shows a sequence of messages indicating the state of the card.
Note It is normal for some displayed messages to appear too briefly in the LED display to be read.
Troubleshooting the Switch Fabric Card
If the installed or replaced switch fabric card fails to operate or to power up on installation:
1. Make sure that the card is seated firmly in the Cisco CRS 8-slot line card chassis slot. One easy way to verify physical installation is to see whether the front faceplate of the switch fabric card is even with the fronts of the other cards installed in the card cage.
2. 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 switch fabric card.
3. Examine the alarm LEDs on the RP to see if there are any active alarm conditions.
4. Examine the power shelves to see whether the chassis, as a whole, is receiving power.
Switch Fabric Card Status LEDs
Use the status LEDs, located on the switch fabric card faceplate, to verify the correct installation of the card:
•When the card is properly installed, the Status turns green. If this LED is off, verify that the card is installed correctly.
•When the Status is blinking yellow, a problem exists on the board.
•When the Status is off, the board state is unknown. Verify that there is power to the board by looking at the indicators on the power module.
•If there is a failure during the board boot sequence, the two-row, four-character alphanumeric display indicates the current boot phase to assist you in debugging the board failure.
How to Install or Remove an MSC, FP, or LSP
This section contains the following procedures:
•Installing an MSC, FP, or LSP
•Removing an MSC, FP, or LSP
•Verifying the Installation of an MSC, FP, or LSP
Installing an MSC, FP, or LSP
This section describes how to install an MSC, FP, or LSP line card in the Cisco CRS 8-slot line card chassis. For more detailed information on the line card , see Cisco CRS Carrier Routing System 8-Slot Line Card Chassis System Description.
The MSC, FP, and LSP line cards are Layer 3 forwarding engines in the Cisco CRS Series routing system (see Figure 4-22). A line card can be paired with different types of physical layer interface modules (PLIMs) to provide a variety of interfaces.
Three MSCs exist: CRS-MSC, CRS-MSC-B, and CRS-MSC-140G. Two FPs exist: CRS-FP40 and CRS-FP-140. One LSP exists: CRS-LSP.
All card versions provide the same functionality, except that the CRS-MSC-140G MSC, CRS-FP-140, and CRS-LSP LSP cards provide 140 Gbps capability.
A line card fits into any available MSC slot and connects directly to the midplane. If you install a new line card, you must first remove the MSC impedance carrier from the available slot.
Figure 4-22 shows the CRS-MSC-140G MSC. The other MSC, FP, and LSP cards are similar.
Figure 4-22 Modular Services Card (CRS-MSC)
Prerequisites
Note See Chapter 1, "Overview," for information on MSC slot types, numbers, widths, and locations.
Caution Remove or install only one line card at a time. Allow at least 15 seconds for the router to complete the preceding tasks before removing or installing another line card. The router may indicate a hardware failure if you do not follow proper procedures.
Caution Do not carry an MSC by the bracket attached to the faceplate.
Required Tools and Equipment
You need the following tools and part to perform this task:
•ESD-preventive strap
•Medium flat-blade or Phillips screwdriver
•MSC, FP, or LSP line card (see the product data sheet for ordering details).
Steps
To install a line card, see Figure 4-23 and follow these steps:

Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to an ESD connection socket on the rear (MSC) side or a bare metal surface on the chassis.
Step 2 Choose an available MSC slot for the MSC.
Caution To prevent ESD damage, handle a line card by its ejector levers or the card carrier edges only. Do not touch any of the electrical components, pins, or circuitry.
Step 3 Remove the MSC impedance carrier from the slot you need to fill and set it aside.
Note Remove only one impedance carrier and install one MSC at a time. Be sure to verify that each line card is fully installed and secured before installing another card.
Step 4 Remove the line card you are installing from its antistatic packaging.
Step 5 Visually inspect the connector on the card before you insert it into the chassis. Do not attempt to install a card with a damaged connector, as this action may damage the chassis midplane pins.
Step 6 Use both hands while inserting an line card. Use one hand on the faceplate and the other hand along the base of the line card to guide it into a slot.
Step 7 Orient the line card so that the PCB faces left and the carrier is to the right; if the card does not slide easily into the slot, the orientation may be wrong and the misorientation rejection flange is stopping the card from going into the slot. Reorient the line card, if necessary.
Step 8 Make sure that the ejector levers are oriented properly to engage with the pin as the line card slides into the slot. Carefully slide the line card into the slot until the ejector levers engage the catches, then stop.
Step 9 Simultaneously pivot the ejector levers toward the faceplate of the line card. Do not force the line card; the ejector levers properly seat the line card against the midplane.
Note If the captive screws are difficult to tighten, check to ensure that each ejector lever is properly secured to each catch and that the line card is properly seated in the slot.
Step 10 Partially tighten the two captive screws on the front panel of the card (either by hand or with the screwdriver) to make sure that they are both engaged.
Step 11 Use a screwdriver to fully tighten the captive screws next to each line card ejector lever to ensure proper EMI shielding and to prevent the card from becoming partially dislodged from the midplane.
Caution To ensure adequate space for additional PLIMs or line cards, always tighten the captive installation screws on each newly installed PLIM before you insert another PLIM or line card. These screws also prevent accidental removal and provide proper grounding and EMI shielding for the system.
Step 12 Attach the bracket to the line card; use the screws that came with it.
What to Do Next
After performing this task:
•Place the impedance carrier in an antistatic bag for storage and future use.
•Replace any front cover cosmetic plates and verify that the card has been installed properly (see the "Verifying the Installation of an MSC, FP, or LSP" section).
•If you are performing the initial installation of the system, install the RP cards (see the "How to Install or Remove an RP, PRP, or DRP PLIM" section).
Removing an MSC, FP, or LSP
This section describes how to remove a line card from the Cisco CRS 8-slot line card chassis. For more detailed information on the line cards, see Cisco CRS Carrier Routing System 8-Slot Line Card Chassis System Description.
Prerequisites
Note For information on MSC slot types, numbers, widths, and locations see Chapter 1, "Overview."
Caution Use the cable management bracket to slide cards from the card carrier.
Do not lift cards by the cable management bracket! Rotate cards onto their vertical axes, then lift them from the bottom, using the cable management bracket only as an aid for balance.
Required Tools and Equipment
You need the following tools and part to perform this task:
•ESD-preventive strap
•Medium flat-blade or Phillips screwdriver

Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to an ESD connection socket on the rear (MSC) side or a bare metal surface on the chassis.
Step 2 Use a screwdriver to loosen the captive screw next to each MSC ejector lever.
Caution To prevent ESD damage, handle a line card by its ejector levers or the card carrier edges only. Do not touch any of the electrical components, pins, or circuitry.
Step 3 Simultaneously pivot the ejector levers away from the faceplate to release the line card from the midplane connectors.
Step 4 Grasp the cable management bracket and gently pull the line card halfway from the slot.
Step 5 Move one hand under the line card to guide it.
Avoid touching the line card printed circuit board, components, or any connector pins. Do not lift cards by the cable management bracket—lift the cards from the bottom, using the cable management bracket only as an aid for balance.
Step 6 Place the removed line card on an antistatic mat, or immediately place it in an antistatic bag if you plan to return it to the factory.
Step 7 If the MSC slot is to remain empty, install an MSC impedance carrier to keep dust from the chassis and maintain proper airflow through the MSC compartment.
Step 8 Use a screwdriver to tighten the captive screws next to each impedance carrier ejector lever to ensure proper EMI shielding and to maintain proper airflow throughout the chassis.
What to Do Next
If you did not place the line card in an antistatic bag, do so now for storage and future use.
Verifying the Installation of an MSC, FP, or LSP

Understanding the Alphanumeric LEDs
At one end of the faceplate, near an ejector lever, a line card has two four-digit alphanumeric LED displays that show a sequence of messages indicating the state of the card.
Note It is normal for some displayed messages to appear too briefly in the LED display to be read.
Troubleshooting the MSC, FP, or LSP
If the installed or replaced line card fails to operate or to power up on installation:
1. Make sure that the card is seated firmly in the Cisco CRS 8-slot line card chassis slot. One easy way to verify physical installation is to see whether the front faceplate of the MSC is even with the fronts of the other cards installed in the card cage.
2. 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 MSC.
3. Examine the Cisco CRS 8-slot line card chassis alarm LEDs on the RP to see if there are any active alarm conditions.
4. Examine the Cisco CRS 8-slot line card chassis power distribution units (PDUs) to see whether the chassis, as a whole, is receiving power.
Status LEDs
Use the status LEDs, located on the line card faceplate, to verify the correct installation of the card:
•When the card is properly installed, the Status LED turns green. If this LED is off, verify that the card is installed correctly.
•When the Status LED is blinking yellow, a problem exists on the board.
•When the Status LED is off, the board state is unknown. Verify that there is power to the board by looking at the indicators on the power module.

•Installing a PCMCIA Card
•Removing an RP PCMCIA Card
For more detailed information on the route processor card, see Cisco CRS Carrier Routing System 8-Slot Line Card Chassis System Description.
Installing an RP, PRP, or DRP Card
This section describes how to install a route processor (RP), performance route processor (PRP), or distributed route processor (DRP) card in the chassis.
Every Cisco CRS 8-slot line card chassis contains two RP cards in dedicated slots on the front (PLIM) side of the chassis (see Figure 4-28).
Note A chassis may not be populated with a mix of RP and PRP cards. Both route processor cards should be of the same type (RP or PRP).
Note For enhanced immunity to external electromagnetic disturbance levels of 10V per meter and 10 V RMS, you must use a shielded Ethernet (CAT5 or better STP) cable on the Management Ethernet connection of the RP card (CRS-8-RP). The use of a shielded Ethernet cable on the Management Ethernet connection of the PRP card (CRS-8-PRP-6G or CRS-8-PRP-12G) is optional. The grounded end of the shielded Ethernet cable should be at the RP (or PRP) end.
Prerequisites
Because chassis operation may be impacted by the installation of a route processor card, perform these tasks only if one of the following conditions exists:
•When you are certain that the second RP in the chassis is operational and, if not already the active RP, ready to assume control (this happens automatically)
•When the chassis is undergoing scheduled maintenance
•When the Cisco CRS 8-slot line card chassis is powered down
Failure to follow these guidelines can result in interruptions in data communications and network connectivity.
Figure 4-28 Route Processor (RP) Card for the 8-Slot Chassis
Required Tools and Equipment
You need the following tools and part to perform this task:
•ESD-preventive wrist strap
•Large Phillips screwdriver.
•RP, PRP, or DRP card:
–RP card—Cisco product number: CRS-8-RP=
–PRP card—Cisco product number: CRS-8-PRP-6G=
–PRP card—Cisco product number: CRS-8-PRP-12G=
–DRP card—Cisco product number: CRS-DRP-CPU=
Steps
To install an RP or DRP card, follow these steps:
Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to an ESD connection socket on the front (PLIM) side or a bare metal surface on the chassis.
Step 2 Remove the card from its antistatic packaging.
Step 3 Visually inspect the connector pins on the card before you insert it into the chassis. Do not attempt to install a card with bent pins, as this may damage the chassis midplane connectors.
Step 4 Identify the card to be replaced in the card cage. Remove any cables connected to the front panel of the card.
Step 5 Use the screwdriver to turn the two captive screws on the front panel of the card counterclockwise to loosen the card from the slot.
Step 6 Grasp the two card ejector levers and simultaneously pivot both ejector levers 90 degrees away from the front edge of the card carrier to unseat the card from the backplane connector.
Step 7 Touching only the metal card carrier, slide the card from the slot and place it directly into an antistatic sack or other ESD-preventive container. If you plan to return the defective card to the factory, repackage it in the shipping container you received with the replacement card.
Step 8 Grasp the card carrier handle with one hand and place your other hand under the carrier to support and guide it into the correct slot. Slide the card halfway into the slot. Avoid touching the card circuitry or any connectors.
Note Alignment grooves exist on each slot in the card cage. When you install a card in the card cage, make sure that you align both edges of the card carrier in the slot grooves.
Step 9 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 may bind when you attempt to close the ejector levers, thereby damaging or breaking one or both ejector levers.
Step 10 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 An RP or DRP card has guide pins that make initial contact with the backplane connector as you slide the 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 11 To seat the card in the backplane 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 12 Partially tighten the two captive screws on the front panel of the card (either by hand or with the screwdriver) to make sure that they are both engaged.
Step 13 Use the screwdriver to turn the two captive screws on the front panel of the card clockwise to seat the card firmly in the slot.
Step 14 Reattach any cables you removed in Step 3.
What to Do Next
After performing this task:
•Place the impedance carrier in an antistatic bag for storage and future use.
•Replace any front cover cosmetic plates and verify that the card has been installed properly (see the "Verifying the Installation of an RP, PRP, or DRP Card" section).

Understanding the Alphanumeric LEDs
At one end of the faceplate, near an ejector lever, an RP, PRP, or DRP card has an alphanumeric LED display that shows a sequence of messages indicating the state of the card.
Note It is normal for some displayed messages to appear too briefly in the LED display to be read.
Troubleshooting the RP, PRP, or DRP Card
If the installed or replaced card fails to operate or to power up on installation, do the following:
1. Make sure that the card is seated firmly in the Cisco CRS 8-slot line card chassis slot. One easy way to verify physical installation is to see whether the front faceplate of the card is even with the fronts of the other cards installed in the card cage.
Note PRP cards only—If the PRP is not seated properly, the blue OIR Ready LED on the faceplate glows solidly, and the Primary and Status LEDs keep blinking to indicate that the card is not seated correctly. If this happens, remove the card fully and re-insert fully.
2. 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 card.
3. Examine the alarm LEDs on the to see if there are any active alarm conditions.
4. Examine the power shelves to see whether the chassis, as a whole, is receiving power.
Status LEDs
Use the status LEDs, located on the card faceplate, to verify the correct installation of the card:
•When the card is properly installed, the Status LED turns green. If this LED is off, verify that the card is installed correctly.
•When the Status LED is blinking yellow, a problem exists on the board.
•When the Status LED is off, the board state is unknown. Verify that there is power to the board by looking at the indicators on the power module.
•When the Primary LED is on, the board is executing control processing functions and is not in a secondary or standby role.
•If there is a failure during the board boot sequence, the four-row, four-character alphanumeric display indicates the current boot phase to assist you in debugging the board failure.

Step 7 Slide the card from the slot and place it directly into an antistatic sack or other ESD-preventive container.
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
Some PLIMs contain Class 1 lasers, and some contain Class 1M. See the documentation for the specific PLIM for details.
What to Do Next
After performing this task, replace any front cover plates.

Troubleshooting the PLIM
If the installed or replaced PLIM fails to operate or to power up on installation:
•Make sure that the PLIM is seated firmly in the Cisco CRS 8-slot 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.
•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.
•Examine the alarm LEDs on the RP to see if there are any active alarm conditions.
•Examine the power shelves to see whether the chassis, as a whole, is receiving power.
Use the status LEDs, located on the PLIM faceplate, to verify the correct installation of the card:
There are two types of LEDs on a PLIM: the board-level LED labeled Status and the port-level LEDs that are labeled differently depending on the PLIM type. When the PLIM is properly installed, the Status LED turns green. If this LED is off, verify that the associated MSC, FP, or LSP line card is installed correctly. For details on the information provided by the port-level LEDs, see the documentation specific to that PLIM.

Prerequisites
Before removing a module, disconnect any connected interface cables.
Required Tools and Equipment
You need the following tools to perform this task:
•ESD-preventive wrist strap
•Small flat-blade screwdriver
Steps
To remove a bale clasp SFP module (from a PLIM), follow these steps:
Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to an ESD connection socket on the front (PLIM) side or a bare metal surface on the chassis.
Step 2 Disconnect and remove all interface cables from the ports. Be sure to note the current connections of the cables to the ports on the PLIM.
Step 3 Open the bale clasp on the module with your index finger in a downward direction (see Figure 4-39). If the bale clasp is obstructed and you cannot use your index finger to open it, use a small screwdriver or other long, narrow instrument to open the bale clasp.
Step 4 Grasp the module between your thumb and index finger and carefully remove it from the port (see Figure 4-39).
Note Be careful to hold the module in such a way so as to not damage the bale clasp.
