Error Message C4K_CHASSIS-3-TRANSCEIVERSERIALINTEGRITYCHECKFAILED: transceivers on
ports [char] and [char] have duplicate serial numbers
Explanation
port in the faulty status.
All transceivers must have a unique serial number. If this message appears you likely have a cloned
transceiver SEEPROM.
Recommended Action
Error Message C4K_CHASSIS-3-STUBPHYMISMATCH: Stub type mismatch: stub [dec]/[dec] is
type [dec], should be type [dec]
Explanation
Recommended Action
Error Message C4K_CHASSIS-3-SUPERVISORTYPEMISMATCHINSPROM: Supervisor's FPGA
register type is [dec], but supervisor's serial eeprom type is [dec]
Explanation
supervisor engine's serial EEPROM. This might happen if the IDPROM is misprogrammed or the
supervisor engine's FPGA register somehow returns an incorrect value. Both are extremely unlikely.
Recommended Action
using the show idprom supervisor command. The output should be the same as the number printed
in this log message for the FPGA register type. This should never happen with a production
supervisor engine. If it does, replace the supervisor engine.
Error Message C4K_CHASSIS-3-TEMPERATURESENSORREADFAILED: Failed to read the
supervisor temperature sensor
Explanation
overheated, this condition will not be reported.
Recommended Action
is required. If this message appears repeatedly (once every 30 minutes), inspect and, if necessary,
replace the temperature sensor on the supervisor engine.
Error Message C4K_CHASSIS-3-UNKNOWNLINECARD: Unknown module (Field Replaceable Unit

Replace the transceiver with a transceiver that Cisco supports.
The stubs have non-matching physical types for the specified module.
Verify that the physical types for every stub on the module match.
