GBIC_SECURITY_UNIQUE Messages
GBIC_SECURITY_UNIQUE Messages
Note The switch supports SFP modules and does not support GBIC modules. Although the error message text
refers to GBIC interfaces and modules, the messages from the switch actually refer to the SFP module
interfaces and modules.
Error Message GBIC_SECURITY_UNIQUE-3-DUPLICATE_GBIC: GBIC interface [dec]/[dec] is
a duplicate of GBIC interface [dec]/[dec].
Explanation
The SFP module was identified as a Cisco SFP module, but its vendor ID and serial
number match that of another interface on the system. The first [dec]/[dec] is the interface of the
duplicate SPF module, and the second [dec]/[dec] is the interface of the existing module.
Recommended Action Cisco SFP modules are assigned unique serial numbers. Verify that the module
was obtained from Cisco or from a supported vendor.
Error Message GBIC_SECURITY_UNIQUE-4-DUPLICATE_SN: GBIC interface [dec]/[dec] has
the same serial number as another GBIC interface.
Explanation
The SFP module was identified as a Cisco SFP module, but its serial number matches
that of another interface on the system. [dec]/[dec] is the interface in which the duplicate module is
installed.
Recommended Action Cisco SFP modules are assigned unique serial numbers. Verify that the module
was obtained from Cisco or from a supported vendor.
HARDWARE Messages
Error Message HARDWARE-2-FAN_ERROR: Fan [chars] Failure
Explanation
The switch fan is not working. [chars] is the fan name.
Recommended Action This is a hardware failure. The fan might recover automatically. If the fan
failure persists, copy the message exactly as it appears on the console or in the system log. Research
and attempt to resolve the error by using the Output Interpreter. Use the Bug Toolkit to look for
similar reported problems. If you still need assistance, open a case with the TAC, or provide your
Cisco technical support representative with your information. For more information about the online
tools and about contacting Cisco, see the “Error Message Traceback Reports” section on page 1-5.
