3Com 3CB9RG4 CoreBuilder 9000, Switch 4007 4-Port 1000Base Gigabit Ethernet Layer 3 Module

For the CoreBuilder 9000 / 4007 Enterprise Switch

Module Description

The 4-port Gigabit Ethernet Layer 3 Switching Module (GBIC) (Model Number 3CB9RG4) for the CoreBuilder 9000 /4007 Enterprise Switch provides high-port-density, line speed, Gigabit Ethernet switching and routing on backbone networks running at Open Systems Interconnection (OSI) Layer 3.

The module offers the following connectivity:

Four Gigabit Interface Converter (GBIC) ports on the front panel can be either 1000BASE-LX (single-mode fiber) or 1000BASE-SX (multimode fiber).
Four Gigabit Ethernet ports connect the module to the chassis backplane.
Key Features

The 4-port Gigabit Ethernet Layer 3 Switching Module (GBIC) supports the following key features:

High-density Gigabit Ethernet switching through the following maximum number of GBIC front panel ports:

-- 24 ports in the 7-slot chassis and 8-slot chassis
-- 56 ports in the 16-slot chassis

Ability to use multimode and single-mode 1000BASE-LX GBICs and multimode 1000BASE-SX GBICs simultaneously on the front panel

Ability to replace the module and GBIC ports while the chassis is operating (which is known as hot swap)

Stand-alone operations if a switch fabric module fails or is not installed

Full-duplex port operation (through front panel ports and backplane ports)

Management using the CoreBuilder 9000 Administration Console command line interface, Web Management suite of applications, or the Simple Network Management Protocol (SNMP)
