IOSMODPORTMAN-4
Error Message C4K_IOSMODPORTMAN-4-CRITICALTEMP: Chassis temperature is at or over
critical threshold - current temp: [dec]C, critical threshold: [dec]C
Explanation
The chassis temperature is above a critical threshold. If some action is not taken
immediately to cool the chassis, the system shuts down to prevent damage to the hardware.
Recommended Action Remove one or more modules to reduce the temperature of the chassis, and
check if the fan tray is functional.
Error Message C4K_IOSMODPORTMAN-4-CLOCKMODULEFAULTY: Clock module switched to [dec]
reason [char] for more info use the cmd:'show environment status clock'
Explanation
The clock module is faulty and may have to be replaced.
Recommended Action Contact your technical support representative to confirm that replacing the
clock module is necessary.
Error Message C4K_IOSMODPORTMAN-4-INLINEPOWEROVERMAX:Inline power exceeds max
threshold:Module status changed to 'Pwr Max'
Explanation The measured PoE usage is higher than the module's physical limit. This situation can
be caused by misconfiguration or by one or more unauthorized appliances drawing more PoE than
allocated. In installations with a 1400 W DC power supply, this warning can be a false positive.
Refer to bug id CSCef49715.
Recommended Action Make sure that the right amount of PoE is allocated to each device. If the PoE
allocation is correct, remove powered devices one at a time and see if the power usage decreases as
expected. (You can use the show power detail command to see the PoE allocated to the module and
the PoE used.) If the power usage decreases sharply when a device is disconnected, chances are that
this device is using more PoE than allocated. Avoiding using this device should solve your problem.
If after disconnecting all the devices on the module, the PoE usage is still high, and the system does
not use 1400 W DC power, contact you technical support representative.
Error Message C4K_IOSMODPORTMAN-4-MODULECRITICALTEMP: Module [dec] Sensor [char]
temperature i s at or over critical threshold - current temp: [dec]C, critical
threshold: [dec]C
Explanation
A module temperature is above its critical threshold. If some action is not taken
immediately to cool down the module then the module will be shut down to prevent damage to
hardware.
Recommended Action Try removing and reinserting the module. If the problem persists, replace the
module.
