GBIC Transceiver Installation Guide
Inserting the
Transceiver
Before you connect the system to the Gigabit Ethernet network, first
insert the transceiver into the GBIC port on the system, as described in
this section. The procedure is similar for all relevant chassis.
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 CoreBuilder
®
3500, 9000, and 9400, see this

Orient the transceiver so that the duplex SC 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.
