70-km Gigabit Ethernet

GBIC Transceiver

Installation Guide

For 3Com Gigabit Interface Converter (GBIC) Transceivers

Description

The Gigabit Interface Converter (GBIC) ports on your system connect to

Gigabit Ethernet networks through a GBIC transceiver (Figure 1),

providing a high-speed connection over fiber-optic cable. The transceiver

connects to the network using a fiber-optic duplex Subscriber Connector

(SC). You can remove and replace the transceiver with the system on

(which is called hot-swapping).

Figure 1 70-km Gigabit Ethernet GBIC Fiber-Optic Transceiver

To ensure optimal performance, compatibility, and regulatory compliance,

use only GBIC transceivers that 3Com supports. For a list of currently

supported GBICs, see this 3Com Web site:
