70-km Gigabit Ethernet GBIC Transceiver Installation Guide

CAUTION: GBIC transceivers are keyed and can be properly inserted only

one way. If the transceiver does not click when you insert it, turn it over

and reinsert it.

Removing the Transceiver

To replace an existing GBIC transceiver, compress the side tabs and gently

pull the old transceiver out of the port.

After you insert the GBIC transceiver into the port, the system software

verifies the transceiver operation, as discussed in this section.

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:
