Removing and Installing a Switch Fabric Card
The three SFCs occupy the three half-width slots on the lower right side of the
chassis. (See Figure 6-31.) Figure 6-34 shows a partially-ejected SFC.
Note Two CSCs (redundant configuration) are required to support CSC online insertion
and removal (OIR). This allows you to remove and replace a CSC or an SFC while
the system remains powered on. If only one CSC is present, do not remove any
cards while the system is powered on.
Caution When removing an SFC, remove the card entirely from the chassis and place it in
an ESD-safe environment. Do not allow the card to rest partially inserted into the
slot, as this damages the EMI shielding on the card in the slot directly below.
Procedures for removing and installing an SFC are described in these sections:
