Maintaining the Cisco 12008 7-59
Removing and Replacing Switch Cards
Step 2
Grasp the front of the card carrier’s metal faceplate, unseat the card from the
backplane, and slide the SFC out of the slot, supporting the weight of the card
by placing your other hand underneath the card carrier. Store the SFC in an
antistatic bag or in an antistatic rack.
Step 3 If you intend to return the card for repair or replacement, leave the card in its
antistatic bag and prepare a return package for shipment.
Caution Do not place any tools in the lower card cage. Also, be careful not to damage the
honeycomb screen in the air filter assembly. Damaging this screen might restrict the flow
of cooling air through the switch router, causing an overtemperature condition in the router.
Installing an SFC
To install an SFC in the router, perform the following steps:
Note
Before accessing any of the router’s internal components, put on an antistatic wrist
strap and make sure that it makes ample contact with your skin. Insert the equipment end
of the wrist strap (the banana jack) into the ESD socket in the lower left corner of the upper
card cage.
Step 1 With one hand, grasp the new SFC by its faceplate; support the weight of the
card by placing your free hand beneath the card carrier.
Step 2
Position the card horizontally and insert it into the vacant slot until the SFC is
firmly seated in the backplane (see Figure 7-17).
Step 3
Restore the air filter assembly to the router to fully enclose the lower card cage.
Secure the assembly in place by tightening its two panel fastener screws.
This completes the procedure for removing and installing an SFC.
To verify the operability of the new SFC, perform the procedure in the section entitled
“Checking the Installation of Switch Cards.”
