I have a Cisco 3825 with an HWIC-D-9-ESW-POE module. I had a Cisco 7940 VoIP phone configured and operating fine on the fa 0/1/0 port. Recently I discovered my VoIP was not getting power and I noticed a solid amber LED on the fa 0/1/0 port. I checked the port and did a "show power inline" and discovered that the fa 0/1/0 port configuration and changed to off. I reconfigured it back to auto and the setting took and the amber LED disappeared. However, my VoIP is still not getting power. I tried the VoIP in the other ports (fa 0/1/1 - 0/1/7) with the same results. I also tried a known good working VoIP with the same results. I have cycled power on the router and reseated the HWIC module, and still no change in status.
I am trying to narrow this problem down to an defective HWIC, power module daughter board, or an inline power supply. Haven't found too much in the way of fault isolation for this and would appreciate any and all suggestions/feedback.
