When the Module is installed you can configure it
through your Switch. Refer to the “ Implementation
Guide” and the “Management Interface Reference
Guide” supplied on the CD-ROM that accompanies your
Switch for more information.
Troubleshooting GBIC Transceivers
After you insert the GBIC transceiver into the port, the
Switch management software verifies the transceiver
operation. If the transceiver is not working properly, the
software displays one of the following error messages:
Invalid GBIC fitted
The GBIC transceiver is invalid and will not be
recognised by the Module.
To be recognised as valid, the GBIC transceiver must
have the following characteristics:
■
1000BASE-SX, 1000BASE-LX or 1000BASE-LH70
media type
■
Fiber SC connector
■
Type 4 GBIC with internal EEPROM fitted
Faulty GBIC fitted
The GBIC transceiver is faulty and will not operate
within the Module.
To correct these problems, completely remove the
transceiver and then reinsert it. If the problem persists,
contact 3Com Technical Support.
Device Mimic States
The Web interface management software on the Switch
displays the Device Mimic, which is an interactive
representation of the currently selected unit. The
following states are displayed for the GBIC Module
when it is installed:
If you suspect a problem, carry out these steps
before
contacting your supplier:
Ensure that the Module is correctly installed in the
Switch and that the three captive thumbscrews which
secure the Module are tightened with a suitable tool.
Ensure that the Switch in which the Module is fitted
is powered-up.
Ensure that the device at the far end of the link is
powered-up and operating correctly.
Ensure that all connectors on the fiber optic segment
are correctly engaged.
Clean the terminators by wiping them gently with a
clean tissue or cotton bud moistened with a little
ethanol. Dirty fiber terminators on the fiber optic
segment impair the quality of the light transmitted
through the cable.
For more general problem solving information, refer to
the documentation supplied with your Switch.
