4-port Gigabit Ethernet Interface Module

Model Number: 3CB9LG4
The 4-port Gigabit Ethernet (GEN) Interface Module
(GBIC) is an interface for gigabit rate data between
the Switch 4007 chassis backplane and other
802.3z-compliant Gigabit Ethernet devices. The
module provides four Gigabit Ethernet fiber-optic
connections on the front panel, using plug-in Gigabit
Interface Converter (GBIC) transceivers. The module
occupies a single interface module slot in the
Switch 4007 chassis.
Each module has four ports on the front panel.
Figure 12 identifies the components on the front
panel of the module.

Gigabit Ethernet Interface Module (GBIC) Quick Start
Guide on the Online Manuals CD-ROM.
9-port 1000BASE-SX Gigabit Ethernet Layer 2
Switching Module
Model Number: 3CB9LG9MC
The 9-port 1000BASE-SX Gigabit Ethernet Layer 2
Switching Module can switch Gigabit Ethernet (GEN)
connections to corporate backbones and servers. The
module has nine 1000BASE-SX GEN front panel
ports. It has 3 backplane ports for connection to the
4007 M
ODULES
24-port GEN Switch Fabric Module, and 1 backplane
port for connection to the 9-port GEN Switch Fabric
Module. The module occupies a single interface
module slot in the Switch 4007 chassis.
Figure 13 identifies the components on the front
panel of the module.

CD-ROM.

4-port Gigabit MultiLayer Switching Module

Model Number: 3CB9RG4
The 4-port Gigabit Ethernet Layer 3 Switching
Module (GBIC) for the Switch 4007 provides
high-port-density, line speed, Gigabit Ethernet
switching and routing on backbone networks running
at Open Systems Interconnection (OSI) Layer 3.
The module provides 4 Gigabit Interface Converter
(GBIC) ports on the front panel that can be either
1000BASE-LX (single-mode fiber) or 1000BASE-SX
(multimode fiber). 4 Gigabit Ethernet ports connect
the module to the chassis backplane.
