Installing and Removing Line Cards, PLIMs, and Associated Components

This chapter provides instructions on how to install and remove the Cisco CRS Carrier Routing System 16-Slot Line Card Chassis (LCC) cards, physical layer interface modules (PLIMs), and any associated components.


Note
For CRS-X next generation line cards and fabric cards, we recommend that you use a modular configuration power system in the chassis.

About Installing and Removing Cards and Associated Components

This section contains some general information about installing and removing cards, PLIMs, and associated components.

Guidelines for Card Installation and Removal

Guidelines for card installation and removal include the following:

  • 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. You do not need to notify the software or reset the power. You have the option of using the Cisco IOS XR shutdown command before removing a card.

Note
OIR removes power to a specific slot before the switch fabric card is replaced. The power remains on for all other slots.
  • The different cards and PLIMs in the LCC 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 locations of the ejector levers and captive screws vary slightly from card to card, but are, in general, in the same locations: on the upper and bottom ends of the faceplate of the card. The following figure shows the locations of the ejector levers and captive screws (on a modular services card (MSC)).

The following figure shows how to operate the ejector levers. Be sure to operate both levers simultaneously.

Figure 2. Operating Ejector Levers

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.

  • You should install the cards in the following order during the chassis initial installation process:
    • Always install cards in the empty slots first from one side to the other. The chassis is shipped with all slots either containing impedance carriers or covered by slot covers to help maintain chassis stiffness and ensure that the chassis is undamaged during shipment. See the next section.
    • Install the route processor (RP) cards first, the left one before the right one. Tighten the screws only after fully inserting both RP cards.
    • Install the LCC fan controller cards in the same manner.
    • Install the switch fabric cards in the same manner, one shelf at a time.
    • For an MSC, FP, or LSP line card or a PLIM, remove one impedance carrier, install a functional board and tighten the screw, and then repeat the process until all line cards and PLIMs have been installed.

For information about the slot numbers, see Chassis Slot Numbers section.


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.

About Impedance Carriers and Slot Covers

When shipped, some slots in the chassis may contain impedance carriers or are covered by slot covers to help 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 RP Slot Cover, Switch Fabric Slot Cover, PLIM Slot Impedance Carrier, and MSC Slot Impedance Carrier).

Figure 3. RP Slot Cover
Figure 4. Switch Fabric Slot Cover
Figure 5. PLIM Slot Impedance Carrier
Figure 6. MSC Slot Impedance Carrier

For further information on installing and removing the slot covers and impedance carriers, see Installing a Slot Cover, Removing a Slot Cover, Installing an Impedance Carrier, and Removing an Impedance Carrier.

About Hard Drives and PCMCIA Cards

Both replacement and additional optional hard drives and PCMCIA cards are available for both the RP and DRP cards.

The hard drive is an IDE hard drive used for gathering debugging information, such as core dumps from the RPs, DRPs, or line cards. 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 LCC and is optional.


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.

Note
Core dumps are discoverable only through intervention with the LCC system software.

Physically, the RP or 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 RP and DRP cards provide two PCMCIA flash slots, each card providing up to 1 GB of flash storage. One PCMCIA flash subsystem 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 RP or DRP, not removable, and for permanent storage of configurations and images.

About Cable Management Brackets

The 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 cause damage to the cables.

The LCC arrives with a midchassis and upper-chassis horizontal cable management bracket preinstalled on the front (PLIM) side of the chassis, with an optional upper-chassis horizontal cable management bracket available for the rear (MSC) side of the chassis.

The following figure shows the midchassis cable management bracket.

Figure 7. Midchassis Cable Management Bracket (Front [PLIM] Side of Chassis Only)

Alphanumeric LEDs

Understanding the Alphanumeric LEDs

At one end of the faceplate, near an ejector lever, a switch fabric 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 Switch Fabric Card

If the installed or replaced switch fabric card fails to operate or power up on installation:

  • Make sure that the card is seated firmly in the LCC 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 module to see if there are any active alarm conditions. See Cisco CRS Carrier Routing System 16-Slot Line Card Chassis System Description for information on the alarm module.
  • Examine the power shelves to see whether the chassis, as a whole, is receiving power.

Use the Status LED, 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, 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 status is unknown. Verify that there is power to the board by looking at the indicators on the power shelf.
  • If a failure occurs during the board boot sequence, the two four-digit alphanumeric displays indicate the current boot phase to assist you in debugging the board failure.

Installing or Removing a Line Card

This section contains the following procedures:


Note
For CRS-MSC-X and CRS-FP-X next generation line cards, we recommend that you use a modular configuration power system.

Installing an MSC, FP, or LSP Line Card

SUMMARY STEPS

  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.
  2. Choose an available modular services card slot for the line card.
  3. Remove the MSC impedance carrier from the slot you need to fill and set it aside.
  4. Remove the replacement line card from the antistatic bag or mat.
  5. Use both hands while inserting a 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.
  6. 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.
  7. 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.
  8. 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.
  9. Use a screwdriver to tighten the captive screws next to each line card ejector lever to ensure proper EMI shielding and prevent the line card from becoming partially dislodged from the midplane.
  10. Attach the bracket to the line card; use the screws that came with it.

DETAILED 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

Choose an available modular services card slot for the line card.

Caution 

To prevent ESD damage, handle a modular services card by its ejector levers or the line 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 line card at a time. Be sure to verify that each line card is fully installed and secured before installing another card.
Step 4

Remove the replacement line card from the antistatic bag or mat.

Step 5

Use both hands while inserting a 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 6

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 7

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 8

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, ensure that each ejector lever is properly secured to each catch and that the line card is properly seated in the slot.
Step 9

Use a screwdriver to tighten the captive screws next to each line card ejector lever to ensure proper EMI shielding and prevent the line 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 any additional PLIM or line card. These screws also prevent accidental removal and provide proper grounding and EMI shielding for the system.

Step 10

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. Close the cosmetic doors (if installed) and verify that the card has been installed properly (Verifying the Installation of an MSC, FP, or LSP Line Card).

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 LCC . 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 26. Distributed Route Processor PLIM

Note
The distributed route processor (DRP) card and DRP PLIM have no dedicated slots. The DRP card is installed in an open MSC slot and the DRP PLIM is installed in the corresponding PLIM slot.

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 Installing or Removing a PLIM or Installing or Removing a Line Card.

Figure 27. Distributed Route Processor Card

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 About Hard Drives and PCMCIA Cards. For installation or removal information, see Installing or Removing a Card-Based Hard Drive or Installing or Removing a PCMCIA Card.

Installing an RP, PRP, or DRP Card

This section describes how to install a route processor (RP), performance route processor (PRP), or a DRP card in the LCC. Every LCC contains two RP or PRP cards in dedicated slots on the PLIM side of the chassis (see the following figure).


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).

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 primary RP, ready to assume control (this happens automatically)
  • When the chassis is undergoing scheduled maintenance

Understanding the Alphanumeric LEDs

On the card front panel, the 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:

  • Make sure that the card is seated firmly in the LCC 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.
  • 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.
  • Examine the alarm module to see if there are any active alarm conditions. See Cisco CRS Carrier Routing System 16-Slot Line Card Chassis System Description for information on the alarm module.
  • Examine the power shelves to see whether the chassis, as a whole, is receiving power.

Use the card status LED, located on the RP and PRP card front panel, to verify the correct installation of the card:

  • When the card is properly installed, the card status LED turns green. If this LED is off, verify that the card is installed 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.
  • Examine the alarm module to see if there are any active alarm conditions. See Cisco CRS Carrier Routing System 16-Slot Line Card Chassis System Description for information on the alarm module.
  • Examine the power shelves to see whether the chassis, as a whole, is receiving power.

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

  • Status LED—Indicates whether the card is properly seated and operating OK.
    • Green—Card is properly installed and operating OK.
    • Yellow—Problem exists on the card.
    • Off—PLIM is not properly seated or system power is off.

Port Status LED:

    • On—Port is logically active and the laser is on.
    • Off—Port is not active.
