Catalyst 4506 and Modules in Pwr Over state

Hello,

First of all, my excuses for my bad english.

I am experiencing a problem with a Cisco Catalyst 4506.

The switch is filled with 48 port PoE blades (WS-X4248-RJ45V).

The error we receive is:

Sept 5 15:40:12: %C4K_IOSMODPORTMAN-4-INLINEPOWEROVERWARNING: Inline power exceeds threshold: Module status changed to 'Pwr Over'

Sept 5 16:37:04: %C4K_IOSMODPORTMAN-6-INLINEPOWEROK: Inline power within limits: Module status changed to 'Ok'

Sept 5 16:37:04: %C4K_IOSMODPORTMAN-6-MODULEONLINE: Module 6 (WS-X4248-RJ45V S/N: JAB080609GN Hw: 2.0) is online

According to the Cisco website:

Explanation

This message indicates that the measured PoE is at least 50 w higher than the configured value. The switch has either misconfigured PoE or an unauthorized powered device that is connected to the switch and is drawing a lot of PoE.

Out put for the commands sh power details and sh module all are attached.

The switch has no PoE devices on the specific blade.

Atleast not that we know.

Does any one know some other solution?

Thanks in advance.

Re: Catalyst 4506 and Modules in Pwr Over state

it's clear you have plenty of power available.

since this is the case, perhaps you should look at the blade(s) as possible culprits at well.

are these errors appearing regularly or is this just the one instance you've seen these?

are your module(s) resetting due to these power issues? i see blade six came online and i'm wondering if you just inserted it or if it was online, then went offline and back online again.

if you can, remove blade six and see what type of symptoms and/or error messages you get. if you regularly see the errors and then they stop when you remove blade six, have the blade checked out or replaced for a test.

it seems you do have a power issue as your 'efficiency' is at 89; should be 100 in this case. (this with such little draw?)

Re: Catalyst 4506 and Modules in Pwr Over state

Well, blade six went offline on the first row of the log i posted earlier.

The problem is, the log doesn't mention in the message which module went offline.

About the 'efficiency' i noticed this also, what could be causing this? Power supplies are already replaced. PoE is on default settings currently.
