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 6-34shows 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:

•Removing a Switch Fabric Card, page 6-62

•Installing a Switch Fabric Card, page 6-63

•Verifying the Installation of the Switch Fabric Card, page 6-64
