4-Port Gigabit Ethernet Layer 3
Switching Module (GBIC)
Quick Start Guide
For the CoreBuilder
®
9000 Enterprise Switch
Module Description
The 4-port Gigabit Ethernet Layer 3 Switching Module (GBIC) (Model
Number 3CB9RG4) for the CoreBuilder
®
9000 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
)
