Removing a GRP

78-4339-09

Replacing a GRP

Figure 4

Ejector Levers and Captive Installation Screw (Cisco 12012 shown)

To remove a GRP, follow these steps:

Step 1

Turn off system power.

Step 2

If you are replacing the GRP in a system with one GRP, copy the currently running configuration file to
a TFTP server or Flash memory so that you can retrieve it later. (See the

“Copying Files to Flash

Memory” section on page 41

.)

Step 3

Attach an ESD-preventitive wrist strap to yourself and to one of the two ESD connection sockets
located on the front edges of the upper card cage (Cisco 12012, Cisco 12016, or Cisco 12416); to the
ESD connection socket located on the lower left edge of the upper card cage (Cisco 12008); or to bare
metal on the frame.

If you are replacing a GRP, disconnect any devices that are attached to the console or auxiliary ports. If
you are removing a GRP for maintenance and will reinstall the same one, you can leave the devices
attached, provided that doing so will not strain the cables.

Step 4

Using a 3/16-inch flat-blade screwdriver, loosen the two captive screws on the ends of the GRP.
(See

Figure 4

a.)

Step 5

Place your thumbs on the ends of each of the ejector levers and simultaneously pull them both away
from the GRP faceplate (in the direction shown in

Figure 4

b) to release the GRP from the upper card

cage slot and to dislodge the GRP edge connector from the backplane.

Step 6

Grasp the GRP faceplate with one hand and pull the GRP straight out of the slot, keeping your other
hand under the GRP to guide it. (See

Figure 4

.) Keep the GRP edge connector parallel to the backplane.

Caution

Avoid touching the GRP printed circuit board, components, or any edge connector pins.
