CHASSIS Messages
This section contains the chassis (CHASSIS) messages.
CHASSIS-2
Error Message C4K_CHASSIS-2-ALLCHASSISSEEPROMSINVALID: Contents of all chassis's
serial eeproms are invalid
Explanation
The contents of all of the chassis's serial EEPROMs are invalid. In non-redundant
chassis, there is one serial EEPROM, and it is bad. If this is a redundant chassis, there are two serial
EEPROMs, and they are both bad.
Recommended Action Try removing and reinserting the supervisor engine. If that doesn't work, try
power cycling the switch. If the serial EEPROM is still invalid, this chassis should be returned.
Error Message C4K_CHASSIS-2-SUPERVISORSEEPROMINVALID: Contents of supervisor's
serial eeprom are invalid
Explanation
The contents of the supervisor engine's serial EEPROM are invalid. For example, a bad
checksum or the supervisor engine type doesn't match with the other hardware information. This
could happen if the read failed because the supervisor engine isn't seated correctly in the slot.
IOS considers this supervisor engine faulty and will not bring up the chassis' interfaces.
Recommended Action Try removing and reinserting the supervisor engine. If that doesn't work, try
power cycling the switch. If the switch still fails to come online, this supervisor engine should be
returned.
Error Message C4K_CHASSIS-2-INLINEPOWEROFF:Inline power to the switch has been
turned off
Explanation
Software detected that the pass-through current is disabled. This condition will cause
all phones drawing PoE from the switch to be powered off.
Recommended Action If you want PoE, verify that the in-line power switch on the power supply is
turned on.
Error Message C4K_CHASSIS-2-INSUFFICIENTFANSDETECTED:Too few working fans in fan
tray, the chassis will overheat. If not resolved, in 4 minutes all line cards will
be placed into Reset-Mode
Explanation
Two or more fans in the system fan tray or power supplies are malfunctioning, or the fan
tray has been removed. Although this is a minor alarm, system components could overheat and shut
down.
Recommended Action Replace the system fan tray or broken fans.
