Installing a Cisco 12008 3-15
Reinstalling Components in the Router
Step4 Grasp the front edge of the metal card carrier with one hand and place your other
hand under the carrier to support the card’s weight and guide it into the card cage
slot.
Note Alignment grooves at the top and bottom of each slot in the upper card
cage help you to align the cards properly for insertion. Make sure you properly
align the card carrier with these alignment grooves to facilitate card insertion.
Step5 Carefully slide the card carrier into the slot until the ejector levers make contact
with the top and bottom edges of the card cage.
Step6 Grasp the line card ejector levers and pivot them toward the card faceplate until
they are perpendicular to the faceplate. This action completely seats the card in
the backplane.
Step7 Tighten the two captive installation screws at the top and bottom of the card
faceplate.
Go back to Step 3 and repeat the procedure until you have fully repopulated the upper card
cage with the previously removed cards.
Note Card blanks must be installed in the upper card cage to cover any unoccupied slots.
The card blanks help to maintain proper air flow through the router and ensure EMI
compliance.
Reinstalling the Power Supplies in the Router
In this section, it is assumed that you will be reinstalling a power supply that you removed
from the power supply bay in preparation for rack mounting the router (see the section
entitled “Removing a Power Supply from the Router”). It is also assumed that the router
has been mounted in the rack and that you are reinstalling the previously removed
components.
The process of reinstalling a power supply is the reverse of the removal procedure depicted
in Figure3-3.
