SWITCH 7700 COMPONENTS

The chapter describes the following Switch 7700 components:

■ Switch Chassis

■ Switch Backplane

■ Fabric Module

■ Fabric 32 Submodules

■ I/O Modules

■ Power Module

■ Fan Assembly

■ Switch 7700 Specifications

■ Switch 7700 Software Features

Switch Chassis There are three Switch 7700 Models, the 4-Slot, 7-Slot, and the 8-Slot. Table 3 lists

the hardware features of each model.

Switch Backplane The Switch 7700 backplane is part of the integrated chassis and delivers

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

Table 22 describes the status of the 24-port 100BASE-FX MMF FE module LEDs.

The 24-port 100BASE-FX MMF FE module requires a 62.5/125 µm multi-mode

optical fiber cable with an MT-RJ connector and a central wavelength of 1300 nm.

Table 23 describes the specifications of the 24-port 100BASE-FX MMF FE module.
