Fabric Module There are two Fabric modules for the Switch 7700:
■ Fabric 64 (3C16857 or 3C16857R)
■ Fabric 32 (3C16872)
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- or 8-slot chassis
The Fabric module is the core of Switch 7700 system. It has the following
functions:
■ 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
■ Monitors system power and the fan frame
