Removing An Sfc - Cisco Gigabit Switch Router 12008 Installation And Configuration Manual

When you install a new CSC or SFC, the router's OIR capability enables the new card to
be recognized, initialized, and become operational in a transparent manner.
For the procedures in this section, it is assumed that you will be removing and replacing a
switch card from a fully redundant and operational router.
When you replace a failed switch card, only four switch planes remain available to the
router. For the duration of the replacement procedure, no redundant plane exists to take over
if any other switch plane fails.
Under normal operating conditions in a fully redundant system, you would not leave a CSC
slot or an SFC slot vacant for any length of time beyond that required to replace a failed
card.
Two dedicated slots (CSC0 and CSC1) in the middle of the upper card cage are reserved for
exclusive use by CSCs. Three dedicated slots (SFC0, SFC1, and SFC2) in the lower card
cage are reserved for exclusive use by SFCs.
You will need the following tools and parts to install or replace a switch card:
•
1/4-inch flat-blade screwdriver
•
ESD-preventive wrist strap
•
Clock and scheduler card (CSC)—product number GSR8-CSC=
•
Switch fabric card (SFC)—product number GSR8-SFC=
