Fabric Module There are three Fabric modules for the Switch 7750:

■Fabric 64 (3C16857 or 3C16857R)

■Fabric 32 (3C16872)

■PoE Fabric 96 (3C16886)

The Fabric 64 and Fabric 32 are not interchangeable. You can install the Fabric 32 only in a 4-slot chassis. You can install the Fabric 64 only in the 7-slot or 8-slot chassis. You can install the PoE Fabric 96 in all three chassis.

■Connects the I/O modules through the backplane and forwards Layer 2 and Layer 3 data

■Manages and calculates routing

■Performs the switch’s software upgrade and system reset functions
