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 or copper cable. The
transceiver connects to the network using a fiber-optic duplex subscriber
connector (SC) or a RJ-45 connector. You can remove and replace the
transceiver with the system on (which is called hot-swapping).

To ensure optimal performance, compatibility, and regulatory compliance,
