a.
Caution Do not allow a line card to rest partially inserted into a slot, because that will damage the EMI shielding
on the RP or line card in the slot directly below.
b.
c.
One edge of the card carrier faceplate is lined with an EMI-preventive gasket consisting of many raised,

conductive contacts. Be careful not to damage the gasket contacts, because a damaged card carrier gasket
can reduce EMI performance.
d.
e.
f.
Note The line card captive screws must be tightened to meet EMI specification standards.
Note If a line card slot in the card cage is not populated with a line card, a blank line card must be installed
to avoid overheating and to ensure electromagnetic compliance (EMC).
Transferring the Clock and Scheduler Cards, Switch Fabric Cards, and Alarm Cards
Cisco 12006 and Cisco 12406 Routers are equipped with chassis slots for two CSCs, three SFCs, and
two alarm cards. (See
You must remove the two CSCs (or single CSC and CSC filler blank), three SFCs, and two alarm cards
from their slots in the defective chassis and install them in the replacement chassis. The captive screws
of each card must be tightened on the replacement chassis to ensure electromagnetic compliance (EMC).

Each line card must be installed in the same slot in the replacement chassis to match the router's
existing software configuration.
After removing the RP, transfer it to the same card slot in the replacement chassis.
Set both edges of the RP or line card carrier into the card slot carrier alignment grooves on either
side of the card cage.
Pivot the ejector levers outward, away from each other and away from the card faceplate.
Grasp the edges of the metal card carrier with both hands to support and guide the RP or line card
into the slot alignment grooves in the card cage.
Use both thumbs to slide the card carrier into the RP and line card slots until the ejector levers make
contact with the front of the card cage, then stop.
Grasp the two RP or line card ejector levers and pivot them toward the card faceplate until they are
perpendicular to the faceplate, to seat the RP or line card in the backplane connector.
Tighten the captive screws on each side of the card faceplate to prevent the RP or line card from
becoming partially dislodged from the backplane and to ensure proper EMI shielding.
