Installing a Cisco 12008 3-7
Removing Components from the Router
Caution
As you remove the cards from the upper card cage, place them on antistatic mats
for ESD protection until they are reinstalled in the router.
Note
Each line card has a vertical cable-management bracket affixed to it that enables you
to neatly “dress” the network interface cables attached to line card ports. Leave this bracket
in place when removing the line cards from the router. The RP and the CSC do not require
vertical cable-management brackets.
To remove a card from the upper card cage, perform the following steps:
Step 1
Attach an antistatic ESD wrist strap to your wrist; ensure that it makes good
contact with your skin.
Step 2 Insert the equipment end of the wrist strap (the banana jack) into the ESD
connection socket near the lower left corner of the upper card cage. Figure 1-2
shows the location of this socket in the body of the router enclosure.
Step 3
Proceeding from left to right for all of the installed cards in the upper card cage,
write down each card’s type and its location in the card cage.
Step 4
Starting with the left-most card, loosen the two captive installation screws
located at the top and bottom of the card (see Figure 3-2a).
Step 5
Pivot the two card ejector levers away from the faceplate to unseat the card from
the backplane (see Figure 3-2b).
Step 6
Touching only the metal card carrier and the card faceplate, slide the card out of
its slot (see Figure 3-2c) and carefully place it (component side up) on an
antistatic mat for ESD protection.
Note You need not remove any line card blanks that are installed in the upper
card cage.
