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:

If the transceiver is not working properly, the system displays an
appropriate error message, as described in the following sections.
"Unqualified GBIC" Error
If the system detects an unqualified GBIC or a problem with the integrity
of the GBIC, it sets the port type to

WARNING
The GBIC in Port xx is NOT approved by 3Com & may violate
electromagnetic emission or safety requirements for your
country. Refer to 3Com's web page

approved list.
Using a newer version GBIC transceiver (GBIC91, GBIC92, or GBIC97) in a
system running older code (pre-Release 3.0) can generate the above
message. For a list of GBIC devices that are qualified for the CoreBuilder
