Replace Chassis Components

The images in this chapter are only for representation purposes, unless specified otherwise. The chassis' actual

appearance and size may vary.

Note

Whenever you replace any card, you must always ensure to secure the ejector thumbscrews properly.

Replace a Route Processor Card

The router supports up to two redundant Route Processor (RP) cards. When two RP cards are installed in the

router, one acts as an active card and the other as the standby card. If the router has only one RP card installed,

a new RP can be installed in the empty RP slot during operation.

• The replacement procedure for the RP cards is only applicable to the standby RP card. You need to

shutdown the router to replace an RP on a single-RP system. When you shutdown the standby RP card,

the router automatically shuts down the standby Switch Card (SC) as both of them belong to the same

operational domain. For example, when you shutdown RP0, the router shuts down the corresponding

SC0. When you shutdown RP1, the router shuts down SC1.

• To replace an active RP card, you must trigger a failover using the redundancy switchover command.

Note

Statement 1029—Blank Faceplates and Cover Panels

Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages

and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other

equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all

cards, faceplates, front covers, and rear covers are in place.

Warning

Statement 1034—Backplane Voltage

Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when

servicing

Warning

Before you begin

Before replacing the Route Processor (RP) card, you must perform a graceful shutdown of the card to avoid

disk corruption. Use one of the following procedures to perform graceful shutdown of the card:

• unscrew the captive screws, pull the release latch down, and open ejector lever to trigger auto-shutdown

of the card, and then verify that the Status LED is in Off state.

• use the shutdown location location command in admin EXEC mode to shutdown the card. Then use

the show platform command to verify that the Status LED is in Off state.

Procedure

Step 1 Open the packaging for the new RP card, inspect the card for damage, and verify that the card is the same

type as the other RP cards installed in the chassis.

If the RP card is damaged, alert the Technical Assistance Center (TAC).

Step 2 If you are installing the RP card in an empty slot, remove the blank card that is already in that slot by unscrewing

its captive screw and pulling it out of the slot. Go to Step 4.

Step 3 If you are replacing an RP card that is currently in the chassis, remove the existing card from the chassis by

following these steps:

a) Disconnect the following cables from the card:

• Console cable

• Ethernet Management cable

b) If there are any external drives attached to the card through its USB ports, detach those drives.

c) Perform the graceful shutdown of the RP. Run the shutdown location location command in admin EXEC

mode, which gracefully shuts down RP module to prevent any of the file systems from being corrupted.

d) Verify that the RP Status LED for the slot that you specified turns off. Also, you can verify that the card

is in the powered off state by running the show platform command.

e) Rotate the captive screw, press the latch, and rotate the ejector lever away from the front of the card (see

Callouts 1 and 2 in the following figure).

Pull on the lever to slide the card partly out of

the chassis. Release the lever, hold the front of

the card, and pull the card all the way out of the

chassis.

4Rotate the ejector lever away from the card.3

f) Use one hand to hold the front of the card, place your other hand under the card to support its weight, pull

the card out of the chassis, and set it on an antistatic surface or inside an antistatic bag.

Step 4 To install a new card, follow these steps:

a) Pull the middle section of the ejector lever toward the end of the lever and rotate the lever away from the

front of the card.

This action opens the lever so that the card can be fully inserted into the slot.

b) Hold the front of the card with one hand and place your other hand under the card to support its weight.

c) Align the back of the card to the guides in the open route processor slot and slide the card all the way into

the slot (see the following figure).

The card stops when its front is about 0.25 inches (0.6 cm) outside the front of the chassis.

Press the latch upwards.3Slide the back end of the card into the open

route processor slot.

Rotate the captive screw to secure the route

processor card.

4Rotate the ejector lever towards the card.2

d) Rotate the lever all the way to the front of the chassis until it locks in place with a click.

Ensure that the other end of the lever engages behind the front of the slot so that the card fully seats onto

the connectors on the midplane.

e) Rotate the captive screw to secure the card to the chassis. Tighten the screws to 9.7 in-lbs (1.09 N-m) of

torque.

f) Attach the following cables to the card:

• Console cable—Attach to the Console port.

• Management cable—Attach to the Management Ethernet port.

Reload an RP card by using the reload location location command. Verify that the reloaded

RP card is again in the Operational state by using the show platform command.

To verify the mode of RP card, if it is in standby or active mode, use the show platform

domain command.

2. To insert the MPA, locate the guide rails inside the chassis that hold the MPA in place.

3. Carefully slide the MPA all the way in the chassis until the MPA is firmly seated in the MPA interface

connector. When fully seated, the MPA might be slightly behind the faceplate.

The MPA will slide easily into the slot if it is properly aligned on the tracks. If the MPA does not slide easily,

do NOT force it. Remove the MPA and reposition it, paying close attention to engaging it on the tracks. Push

the MPA inside the slot until you hear a click. Continue to push the MPA further until you hear a second click.

The MPA is fully seated only after the second click is heard.

Note

4. After the MPA is properly seated, pull the ejector lever towards the chassis (marked as 2 in the image).

5. Pull the tab up (marked as 3 in the image).

6. Use a number 2 Phillips screwdriver to tighten the captive screws(marked as 4 in the image) on the MPA.
