Hi,
I am getting the following error in my Cisco 4510E switch.
%C4K_IOSMODPORTMAN-4-INLINEPOWEROVERWARNING: Module 3 inline power exceeds threshold: status changed to 'Pwr Over'
show module output is showing the status of the card as "Pwr Over"
IOS-XE version we are using is: cat4500e-universalk9.SPA.03.02.03.SG.150-2.SG3.bin & power supply is 4200W AC.
I suspect it as an unknown bug for this version.
Thanks,

Hi Shahab,
I am not seeing any software defect on this behavior presently. The symptoms are typically generated if one of the PoE devices connected to the module is drawing more power than it should.
Also, please share the below commands to investigate this issue further,
# show idprom power-supply
# show power detail
# show power inline
# show module
Regards,
Aru

Hi
This problem is bug. bug id below.
Symptom: Catalyst 4500 with 1400 DC power supply may report "Pwr Over" or "Pwr Fault" status for the following modules - WS-X4248-RJ45V - WS-X4248-RJ21V - WS-X4548-GB-RJ45V The following logging messages may also be generated %C4K_IOSMODPORTMAN-4-INLINEPOWEROVERWARNING: Measured inline power higher than configured value %C4K_IOSMODPORTMAN-2-INLINEPOWEROVERCRITICAL: Measured inline power exceeds module limit Condition: The above symptoms are typically generated if one of the PoE devices connected to the module is drawing more power than it should. Make sure the connected devices are not drawing more power than expected. However, in systems using 1400W DC power supplies, it is also possible that due to an anomaly in the measuring mechanism in these linecards, the messages and associated status are erroneously displayed. There is NO functionality/performance impact due to this condition. The modules are safe and would have no impact to the operation of the switch or the connected PoE devices. Troubleshooting steps: This situation may be caused by a device that is using more inline power than allocated. Please make sure that the right amount of inline power has been allocated to each device. If the inline power allocation is correct, start pulling out one device at a time and see if the power usage decreases as expected. (You can use the command, "#show power detail" to see the inline power allocated to the module (admin) and the inline power used (operating).) If the "inline power used" decreases sharply when a device is disconnected, chances are that this device is using more inline power than allocated. Avoiding using this device should solve your problem. If after disconnecting all the devices on the module, the inline power usage is still high, and the system does not use 1400W DC power, call TAC.

The bug tells that the issues are seen with DC1400 Power supplies. But in this case, it is a AC 4200W. Is this bug applicable to AC power supplies as well ?
