Chapter 2 Messages and Recovery Procedures
SUPERVISOR Messages
Error Message C4K_SUPERVISOR-3-SEEPROMREADFAILED:Failed to read supervisor's serial
eeprom, try reinserting supervisor
Explanation
A reading of the supervisor engine's serial EEPROM failed. The read might fail if the
module is not seated correctly in the slot.
Recommended Action Remove and reinsert the module. If that does not work, power cycle the switch.
If the read still fails, contact your technical support representative. You may need to return some
switch components for repair or replacement.
SUPERVISOR-4
Error Message C4K_SUPERVISOR-4-INLINEVOLTAGEOUTOFRANGE:Output voltage of the
on-board inline power convertor on this board is [char] and is outside the
expected range of [char]
Explanation
This message should only occur in systems using a Supervisor Engine II-Plus TS. The
output voltage of the on-board inline power converter is outside its expected valid range. This
condition can occur because of failed PoE components, one or more powered devices drawing more
power than expected, or because of problems with the 12 V output of the system power supply.
Recommended Action Use the show power detail and show power inline module 1 commands to
verify that the devices drawing PoE are using the expected amount of power, and disconnect them
if they are drawing more than desired. If the power supply LEDs are not green, verify at the source
that the system power input is correct. If the problem persists, contact your technical support
representative. You will probably need to replace the supervisor engine.
Error Message C4K_SUPERVISOR-4-OTHERSUPERVISORACTIVEDEBOUNCE:Other supervisor is
still holding hardware lock
Explanation
This condition is detected when the redundancy register incorrectly indicates that the
other supervisor engine is holding a lock. This error is probably caused by hardware signal latency.
Unless there is a real hardware failure, the switch automatically recovers from this state. If there is
a persistent hardware failure, this message appears four times.
Recommended Action This is an informational message only. No action is required.
Error Message C4K_SUPERVISOR-4-SUPMGMTMACFATALRXERR:Supervisor MAC device type
[hex] reset due to a fatal Rx error
Explanation An error occurred with the out-of-band management port on the supervisor engine.
Recommended Action This is an informational message only. No action is required.
