Removing and Installing a Clock and Scheduler Card, Switch Fabric Card, or Alarm Card
Cisco 12006 and Cisco 12406 routerss are equipped with chassis slots for two
CSCs, three SFCs, and two alarm cards. (See Figure 6-31.)
Figure 6-31 CSC, SFC, and Alarm Card Slot Locations
Note The Cisco 12006 Router is based on a 2.5-Gbps switch fabric, where each SFC or
CSC provides a 2.5-Gbps full-duplex connection to each line card in the system.
The 2.5-Gbps switch fabric consists of the 12006 Advanced Clock and Scheduler
Card (product number 12006-CSC=) and the 12006 Advanced Switch Fabric Card
(product number 12006-SFC=).
The Cisco 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 and Scheduler Card (product
number GSR6-CSC=) and the Switch Fabric Card (product number GSR6-SFC=).
You cannot mix 2.5-Gbps switch fabric cards and 10-Gbps switch fabric cards in
a chassis. The router will not operate with a mix of switch fabric card types.
