Removing and Installing a Clock and Scheduler Card, Switch Fabric Card, or Alarm Card

The Cisco XR 12406 router is based on a 10-Gbps switch fabric, where each SFC or CSC provides a 10-Gbps full-duplex connection to each line card in the system. The 10-Gbps switch fabric consists of the Clock Scheduler Card and the Switch Fabric Card. The chassis has slots for two CSCs, three SFCs, and two alarm cards (Figure 5-31).

Removing and Replacing a Clock Scheduler Card

If a router is not configured with redundant CSCs, it has one CSC installed in either of the CSC slots, and has a CSC blank filler installed in the second CSC slot.

Caution The CSCs support OIR, so when the router is equipped with two CSCs, you can remove either CSC while the system remains powered on. In a router equipped with only one CSC, you must shut down the router before removing the CSC.
