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.
