3750 Inline power error - Imax error detected

[Erick Bergquist]

Have a 3750 with IOS 12.2(25)SEB2 and have a cisco IP phone on one port that goes down several times a day and loses power. This is error in 3750 switch indicating a issue with inline power on switch.

The port does have Input errors, so I am guessing this Imax error detected is some inline power error threshold being crossed.

Hi

A couple of docs for you, of varying relevance:

http://www.cisco.com/en/US/products/hw/wireless/ps430/products_field_notice09186a00803662a5.shtml

Mentions lots of APs on a switch and seems to indicate that radios can take more power in some situations that can cause this error - perhaps the handset is faulty (though I assume you've tried swapping it?) or a cabling issue is causing Bad Things to happen.

Release notes:

Again possibly a cable issue if not the phone?

Does it happen for this switch port with another phone connected?
