4GBIC Transceiver Installation Guide

Inserting the Before you connect the system to the Gigabit Ethernet network, first Transceiver insert the transceiver into the GBIC port on the system, as described in

this section. The procedure is similar for all relevant chassis or modules.

To ensure optimal performance, compatibility, and regulatory compliance, use only GBIC transceivers that 3Com supports. For a list of GBIC devices that are qualified for the 3Com products see this 3Com Web site:

1Read and follow the instructions in “Safety Precautions” earlier in this guide.

2Orient the transceiver so that the duplex SC or RJ-45 connector is toward you.

CAUTION: GBIC transceivers are keyed and can be properly inserted only one way. If the transceiver does not click when you insert it, remove it, turn it over, and reinsert it.

aFigure 2 shows how to insert the transceiver into a GBIC port. Installation into other chassis is the same except that the chassis ports may be oriented vertically.
