Catalyst 4500: bad inline power and other problem related to inline power

Hello,

I've a catalyst4500 with some IP Phones attached and I got some errors like the following:

Jul 14 08:26:49: %ILPOWER-5-ILPOWER_POWER_DENY: Interface Fa5/15: inline power denied

Jul 14 08:26:50: %C4K_IOSMODPORTMAN-6-POWERSUPPLYOUTPUTINCREASED: Power supply 2 output has increased

Jul 14 08:27:00: %C4K_IOSMODPORTMAN-4-POWERSUPPLYOUTPUTDECREASED: Power supply 2 output has decreased

Jul 14 08:27:00: %C4K_IOSMODPORTMAN-6-INLINEPOWERSUPPLYGOOD: Inline power from power supply 2 is Ok

Jul 14 08:27:00: %C4K_CHASSIS-3-MIXINPOWERDETECTED: Power supplies in the chassis are of different types (AC/DC) or wattage

Jul 14 08:27:05: %C4K_IOSMODPORTMAN-4-POWERSUPPLYBAD: Power supply 2 has failed or been turned off

Jul 14 08:27:05: %C4K_IOSMODPORTMAN-4-POWERSUPPLYFANBAD: Fan of power supply 2 has failed

Jul 14 08:27:05: %C4K_IOSMODPORTMAN-4-INLINEPOWERSUPPLYBAD: Inline power from power supply 2 has failed or been turned off

Jul 14 08:27:10: %C4K_IOSMODPORTMAN-6-POWERSUPPLYGOOD: Power supply 2 is okay

Jul 14 08:27:10: %C4K_IOSMODPORTMAN-6-POWERSUPPLYFANGOOD: Fan of power supply 2 is okay

Jul 14 08:27:10: %C4K_IOSMODPORTMAN-6-INLINEPOWERSUPPLYGOOD: Inline power from power supply 2 is Ok

Jul 14 08:27:15: %C4K_IOSMODPORTMAN-4-INLINEPOWERSUPPLYBAD: Inline power from power supply 2 has failed or been turned off

but from the show power I can see:

Power Fan Inline

Supply Model No Type Status Sensor Status

------ ---------------- --------- ----------- ------- -------

PS1 PWR-C45-4200ACV AC 4200W good good good

PS1-1 220V good

PS1-2 220V good

PS2 PWR-C45-4200ACV AC 4200W good good bad/off

PS2-1 220V good

PS2-2 220V good

so the 2 Power Supply are ok, but one is considered "bad". Why? Do you have any ideas?

Second strange thing is that with only PS1 some phones don't receive inline power and this is not correct because the power consumption is less than the maximum provided of the only PS1. Any ideas?

Thanks

Best regards

Roberto

Re: Catalyst 4500: bad inline power and other problem related to

The second PS seems to be failure, you better claim the RMA or ask the vendor to replace it.

If you have only one PS, the total supported IP phone w/ inline power will be decreased due to lower power of power supply provided.

Try to use below tool from Cisco to calculate the required power / PS.

Hope this helps.
