Guidelines for Card Installation and Removal
This section contains the general guidelines for card installation and removal.
Online insertion and removal (OIR) is supported, enabling you to remove and install cards while the Cisco CRS 4-slot line card chassis 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 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 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.

Recommended Order for Installing Cards
Although it is not critical for you to install the cards in a certain order, following the card installation recommendations in this section will make your installation process easier. We recommend that you install cards in the Cisco CRS 4-slot chassis in the following order:
•Switch fabric cards (SFCs)
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.
•Route processors (RPs) or performance route processors (PRPs)
•Modular services cards (MSCs), forwarding processors (FPs), and label switch processor (LSP) cards
•Physical layer interface modules (PLIMs)
Note See the instructions in this chapter for details on how to install the individual cards.
Guidelines
When you install or remove cards on the Cisco CRS 4-slot line card chassis, follow these guidelines:
•Do not operate the Cisco CRS 4-slot line card chassis with any slots completely empty; doing so can lead to an airflow bypass condition that diverts airflow from slots containing heat-generating electronics. This situation can cause thermal alarms to occur at lower-than-expected ambient temperatures. To avoid airflow bypass, make sure that all slots are 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.
•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.
•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.
PCMCIA Cards
Optional and replaceable PCMCIA cards are available for the RP cards. The RP 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 system images and configurations by plugging in a PCMCIA flash card. The other subsystem is fixed to the RP, is not removable, and is used for permanent storage of configurations and system images.
Note Only the original route processor (RP) card uses a PCMCIA card. The performance route processor (PRP) card has a USB connector for using a flash drive.
Small Form-Factor Pluggable (SFP) Modules
The SFP module for the Cisco CRS 4-slot 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 Shared port adapters (SPAs) and the 16-port OC-48c/STM-16c PLIM use SFP modules.
Cable Management Brackets
The Cisco CRS 4-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 4-slot line card chassis arrives preinstalled with a horizontal cable management bracket on the front of the chassis; this bracket cannot be removed or replaced.
Figure 4-3 shows the chassis cable management bracket.

Step 1 Go to the rear of the chassis. Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection sockets on the rear (SFC) side of the chassis or a bare metal surface on the chassis.
Step 2 Remove the switch fabric card from its antistatic packaging.
Step 3 Use a medium Phillips screwdriver to remove the switch fabric card from its protective carrier.
Step 4 Visually inspect the connector pins on the card before you insert it into the chassis.
Note Do not attempt to install a card with bent pins, because this may damage the chassis midplane connectors.
Step 5 Identify the card slot in the card cage where the switch fabric card should be installed.
a. If there is an impedance carrier in the slot, remove it (see the "Removing an Impedance Carrier" section.)
b. If there is a switch fabric card already installed in the slot, remove the card (see the "Removing a Switch Fabric Card" section).
Step 6 Grasp the face plate of the card with one hand and place your other hand under the card to support and guide it into the correct slot.
Step 7 Orient the route processor card so that the status display is on top, then position the card for insertion into the card cage slot. Avoid touching the card circuitry or any connectors.
Note There are alignment grooves on each slot in the card cage. When you install a card, make sure that you align both the top and bottom edges of the card carrier in the slot grooves.
Step 8 Grasp both card ejector levers simultaneously, then push them both outward until they are fully extended in the open position.
Step 9 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.
Step 10 To fully seat the card in the midplane connector, grasp both card ejector levers simultaneously, then push them both inward until they are flush against the front edge of the card carrier.
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.
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.
Step 11 To seat the card firmly in the slot, use the screwdriver to tighten the captive screws.
What to Do Next
After performing this task:
•Place the impedance carrier in an antistatic bag for storage and future use.
•If you are performing the initial installation of the system, install the RPs or PRPs (see the "Installing an RP or PRP Card" section).

This section describes how to remove a switch fabric card from the Cisco CRS 4-slot line card chassis. For more detailed information on the switch fabric card, see Cisco CRS Series Carrier Routing System 4-Slot Line Card Chassis System Description.
Prerequisites
There are no prerequisites for this task.
Required Tools and Equipment
You need the following tools to perform this task:
•ESD-preventive wrist strap
•Number 1 Phillips screwdriver
Steps
To remove a switch fabric card, see Figure 4-14 and follow these steps:
Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection sockets on the rear (SFC) side of the chassis or a bare metal surface on the chassis.
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 insert only one switch fabric card at a time.
Step 2 Identify the switch fabric card to be removed from the card cage. Use the screwdriver to turn the two captive screws on the front panel of the card counterclockwise to loosen it from the slot.
Step 3 To unseat the card from the midplane connector, grasp the two card ejector levers and simultaneously pivot both ejector levers outward from the front edge of the card slot. As you pivot the ejector levers outward, the switch fabric card is partially pulled from the slot.
Step 4 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.

Alphanumeric LEDs |
Understanding the LEDs
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.
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 LED turns green. If this LED is off, make sure 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.
Troubleshooting the Switch Fabric Card
If the installed or replaced switch fabric card fails to operate or to power up on installation:
•Make sure that the card is seated firmly in the Cisco CRS 4-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.
•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.
•Examine the alarm LEDs to see if there are any active alarm conditions.
•Examine the power shelves to see whether the chassis, as a whole, is receiving power.

Installing an RP or PRP Card
This section describes how to install a route processor (RP) or performance route processor (PRP) card in the chassis (see Figure 4-17). For more detailed information on the route processor card, see Cisco CRS Carrier Routing System 4-Slot Line Card Chassis System Description.
Every Cisco CRS 4-slot line card chassis contains two RP or PRP cards in dedicated slots on the front (PLIM) side of the chassis (see Figure 4-17).
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-4-RP) or PRP card (CRS-4-PRP-6G or CRS-4-PRP-12G).
RP Installation Guidelines
Chassis operation may be effected by the installation of a route processor card. A route processor card is normally installed under one of the following conditions:
•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 4-slot line card chassis is powered down.
Monitoring the RP Card Start-Up Process
Monitoring the RP card during its start-up process must be done through a console port connection. For details, see the latest release of the Cisco IOS XR Getting Started Guide on www.cisco.com.
To monitor the RP card during its start-up, follow these steps:
Step 1 Install the console port connection to the front of the RP.
Tip If you want to monitor the start-up process on the RP, you must physically attach the console port connection and open the console port connection prior to inserting the RP into its designated slot.
Step 2 Insert the RP into its designated slot as described in this section.
Step 3 At the console, verify the status of the RP.

After performing this task:
•Place the impedance carrier in an antistatic bag for storage and future use.
•Verify that the card has been installed properly (see the "Verifying the Installation of an RP or PRP Card" section).
•Connect the console port and LAN port. For more information, see the latest release of the Cisco IOS XR Getting Started Guide on www.cisco.com.
•If you are performing the initial installation of the system, install the MSCs (see the "Installing an MSC, FP, or LSP" section).
Removing an RP or PRP Card
This section describes how to remove a route processor (RP) or performance route processor (PRP) card from the chassis. For more detailed information on the route processor card, see Cisco CRS Series Carrier Routing System 4-Slot Line Card Chassis System Description.
Every Cisco CRS 4-slot line card chassis contains two route processor cards in dedicated slots on the front (PLIM) side of the chassis (see Figure 4-17).
Prerequisites
Because chassis operation may be impacted by the removal of an RP 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 4-slot line card chassis is powered down.
Failure to follow these guidelines can result in interruptions in data communications and network connectivity.
Required Tools and Equipment
You need the following tools to perform this task:
•ESD-preventive wrist strap
•Large (number 1) Phillips screwdriver
Steps
To remove an RP card, follow these steps:
Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection sockets on the front (PLIM) side of the chassis or a bare metal surface on the chassis.
Step 2 Identify the card to be removed from the card cage. Remove any cables connected to the front panel of the card.
Step 3 PRP cards only—Before removing a PRP card, you must first push the OIR button (using a pointed object such as a pen), which causes the blue OIR Ready LED to start blinking. When the board is ready for removal, the blue LED glows solidly.
Step 4 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 5 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 6 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.
Verifying the Installation of an RP or PRP Card
This section describes how to verify and troubleshoot the installation of a route processor (RP) orperformance route processor (PRP) card in the Cisco CRS 4-slot line card chassis. For more detailed information on the RP or PRP card, see Cisco CRS Series Carrier Routing System 4-Slot Line Card Chassis System Description.

Understanding the LEDs
Alphanumeric LEDs
At one end of the faceplate, near an ejector lever, an RP or PRP 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 alphanumeric LED display to be read.
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.
Troubleshooting the RP Card
If the installed or replaced card fails to operate or to power up on installation:
1. Make sure that the card is seated firmly in the Cisco CRS 4-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 faceplete 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 faceplate 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.
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 4-slot line card chassis. For more detailed information on line cards refer to the Cisco CRS Carrier Routing System 4-Slot Line Card Chassis System Description.
The line cards are Layer 3 forwarding engines in the Cisco CRS routing system. A line card can be paired with different types of physical layer interface modules (PLIMs) to provide a variety of interfaces.
There are three versions of the MSC: The original version (CRS-MSC), Version B (CRS-MSC-B), and the CRS-MSC-140G version. .
There are two versions of the FP: The original version (CRS-FP40) and the FP-140 version (CRS-FP-140). Both versions of the card provide the same functionality, except that the FP-140 provides 140 Gbps capability.
There is one LSP: CRS-LSP.
Caution
MSC-140G and FP-140 line cards should only be paired with 20-port and 14-port 10-GE XFP PLIMs and 1-port 100-GE CFP PLIMs. The MSC-40 and FP40 line cards should not be paired with 20-port and 14-port 10-GE XFP PLIMs or 1-port 100-GE CFP PLIMs.
The MSC-40 line card can be paired with all previous PLIMs. The FP40 line card can only be paired with a subset of PLIMs. See the release notes for details.
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 4-20 shows the CRS-MSC-140G MSC. The other MSC, FP, and LSP cards are similar in appearance.
Note If your Cisco CRS 4-slot line card chassis uses a Cisco CRS SIP-800, refer to the "Installing and Removing a SIP" chapter in the Cisco CRS SIP and SPA Hardware Installation Guide on www.cisco.com.
Figure 4-20 Modular Services Card (CRS-MSC-140G)
Prerequisites
Caution
Do not carry a line card by the slide-assistance arm attached to the faceplate (if attached).
Required Tools and Equipment
You need the following tools and part to perform this task:
•ESD-preventive strap
•Small Phillips screwdriver
•Medium flat-blade or Phillips screwdriver
•Card:
–Modular services card (Cisco product number: CRS-MSC, CRS-MSC-B, or CRS-MSC-140G. See the product data sheet for ordering details.)
–Forwarding Processor (FP) card (Cisco product number: CRS-FP40 or CRS-FP-140. See the product data sheet for ordering details.)
–Label Switch Processor card: (Cisco product number: CRS-LSP. See the product data sheet for ordering details.)
Steps
To install a modular services card, follow these steps:
Step 1 Go to the front of the chassis. Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection sockets on the front side of the chassis or a bare metal surface on the chassis.
Step 2 Remove the line card from its antistatic packaging.
Step 3 Use a medium Phillips screwdriver to remove the line card from its protective carrier.
Step 4 Remove the slide-assistance arm (handle) currently attached to the line card:
a. Using a small Phillips screwdriver, turn the two captive screws (one top, one bottom) on the slide-assistance arm counter-clockwise to detach the arm from the card face.
b. Set the slide-assistance arm carefully aside. We recommend storing it in the original Cisco packaging.
Step 5 Visually inspect the connector pins on the card before you insert it into the chassis.
Note Do not attempt to install a card with bent pins, because this may damage the chassis midplane connectors.
Step 6 Identify the card slot in the card cage where the line card should be installed.
a. If there is an impedance carrier in the slot, remove it (see the "Removing an Impedance Carrier" section.)
Note Remove only one impedance carrier and install one line card at a time. Be sure to verify that each line card is fully installed and secured before installing another card.
b. If there is a line card already installed in the slot, remove the card (see the "Removing an MSC, FP, or LSP" section).
Step 7 Grasp the face plate of the card with one hand and place your other hand under the card to support and guide it into the correct slot (see Figure 4-21).

Step 8 Orient the line card so that the status display is on top, then position the card for insertion into the card cage slot. Avoid touching the card circuitry or any connectors.
Note There are alignment grooves on each slot in the card cage. When you install a card, make sure that you align both the top and bottom edges of the card carrier in the slot grooves.
Step 9 Grasp both card ejector levers simultaneously, then push them both outward until they are fully extended in the open position.
Step 10 Carefully slide the line 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 card until the ejector lever hooks are fully latched.
Note Line cards have guide pins that make initial contact with the midplane connector as you slide a card into its slot.
Step 11 To fully seat the card in the midplane connector, grasp both card ejector levers simultaneously, then push them both inward until they are flush against the front edge of the card carrier. After the guide pins make contact, continue pushing the card carrier until the card ejector levers begin pivoting forward.
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 12 To ensure proper EMI shielding and prevent the line card from becoming partially dislodged from the midplane, use a screwdriver to fully tighten the captive screws next to each line card ejector lever.
Caution
To ensure adequate space for additional line cards, always tighten the captive installation screws on each newly installed line card
before you insert another line card. These captive screws also prevent accidental removal and provide proper grounding and EMI shielding for the system.
What to Do Next
After performing this task:
•Place the impedance carrier in an antistatic bag for storage and future use.
•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 PLIMs (see the "How to Install or Remove a Physical Layer Interface Module" section).

Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection sockets on the front (PLIM) side of the chassis or a bare metal surface on the chassis.
Step 2 Using the screwdriver, loosen the captive screw at the bottom of the PCMCIA slot door on the faceplate of the card.
Step 3 While lifting the hinged PCMCIA slot door up, press the release button for the card slot to disengage the card from the card, and then carefully pull out the far left removable PCMCIA flash card.
Step 4 Place the removed PCMCIA card on an antistatic mat, or immediately place it in an antistatic bag if you plan to return it to the factory.
Step 5 If the PCMCIA card slot is to remain empty, close the door to keep dust out and tighten the captive screw with the screwdriver. Otherwise, install the new PCMCIA card.

Removing a Bale-Clasp SFP Module
This section describes how to remove a bale-clasp SFP module. The module has a clasp used to install and remove the module (see Figure 4-33).
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 one of the ESD connection sockets on the front (PLIM) side of the chassis 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 4-35). 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 4-35).
Note Be careful to hold the module in such a way so as to not damage the bale-clasp.
