If the system detects that the transceiver cannot emit the proper laser signal, it disables the port, sets the port type to disabled, displays a short description (GBIC Disable), and captures the error in the event log.
The following message appears in the event log:
Due to excessive TxFault conditions, GBIC Port xx has been
disabled.
Meaning Excessive Tx Fault conditions indicate a faulty GBIC.
Corrective action Replace the transceiver. If the problem persists, contact network supplier or 3Com Technical Support. For contact information, see the Technical Support appendix in the Getting Started Guide for your system.
“Unapproved GBIC” Error
Supported transceivers are those that 3Com has specifically tested and qualified for use with 3Com GBIC systems. Pretesting at 3Com ensures proper functionality, compatibility, and regulatory compliance with the system.
If the system detects a transceiver that 3Com does not support, it sets the port type to Unqualified GBIC, displays a short description, (Unappr.GBIC), and captures the error in the event log.
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 (www.3com.com/gigabit_ethernet/gbics) for our current approved list.
The following informational message is shown in the event log:
Unqualified GBIC: Unqualified vendor part number
Corrective action Although this report does not necessarily indicate that the GBIC transceiver will not function properly with the system, it does indicate that 3Com has not qualified the transceiver and does not support it.
