CHASSIS Messages
Error Message C4K_CHASSIS-3-MUXBUFFERSEEPROMINVALID: Invalid data in mux buffer
[dec]'s serial eeprom
Explanation
The mux buffer serial EEPROM could not be read or has not been programmed.This
message should occur only in a prototype switch used in an early field trial.
Recommended Action Reseat the mux buffers to see if the message is due to a faulty connection. If it
persists, contact your technical support representative. You may need to return some switch
components for repair or replacement.
Error Message C4K_SUPERVISOR-3-MUXMAYMISALIGN:Linecard Mux-buffers may mis-align to
incorrect supervisor due to reset with other supervisor desires to be active
Explanation
While resetting the switching modules and taking them out of reset the other supervisor
engine is trying to become active using hardware hot-standby logic. This may cause incorrect
alignment of the switching module mux-buffers to use the non-active supervisor engine, and the
switch will not be able to pass traffic until the alignment is reset.
Recommended Action Reset the other supervisor engine using the redundancy reload peer
command, and contact your technical support representative to report the failure.
Error Message C4K_CHASSIS-3-LINECARDNOTVALIDINSLOT: Module (Field Replaceable Unit
minor type [dec]) is not supported in slot [dec]
Explanation
The supervisor engine identified the type, but the switching module cannot be supported
in this slot due to the insufficient number of backplane ports in this slot.
Recommended Action This is an informational message only. No action is required. If possible, move
the switching module to another slot, and use a supported module in the original slot.
Error Message C4K_CHASSIS-3-LINECARDSEEPROMREADFAILED:Failed to read module [dec]'s
serial eeprom, try reinserting module
Explanation
The switch cannot read the serial EEPROM of the specified module, and the module will
not boot because the EEPROM failed to identify the module type. The read might fail if the module
is not seated correctly in the slot.
Recommended Action Remove and reinsert the module. If this message reappears, reboot the switch.
If the problem persists, contact your technical support representative. You will likely have to return
the module to Cisco to reprogram or replace the serial EEPROM.
Error Message C4K_CHASSIS-3-LINECARDSEEPROMWRITEFAILED:Failed to write module
[dec]'s serial eeprom
Explanation A write operation to the serial EEPROM failed. The write might fail if the module is not
seated correctly in the slot.
Recommended Action Remove and reinsert the module. If this message reappears, reboot the switch.
If the problem persists, contact your technical support representative. You will likely have to return
the module to Cisco to reprogram or replace the serial EEPROM.
