GBIC_SECURITY_UNIQUE Messages
Note The Catalyst 3750-X, 3750-E, 3560-X, and 3560-E switches support SFP and 10-Gigabit Ethernet
modules and do not support GBIC modules. Although the error message text refers to GBIC interfaces
and modules, the messages from the switches actually refer to the SFP and 10-Gigabit Ethernet 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 GBIC or 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 GBIC or SPF module, and the second [dec]/[dec] is the interface of the existing
module.
Recommended Action Cisco GBIC or 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 require assistance, open a case with the TAC, or contact your
Cisco technical support representative, and provide the representative with the gathered information.
