4620SW IP Rebooting

OK, a few things:

Are your MedPro firmware current?
Have you applied the latest patches to your S8720?

After that, go in the Maintenance Web for your S8720, choose Systems Logs on the left side (you will get a bunch of options to check off); try checking only "IP Events" and at the bottom for "Match Pattern" (don't forget to check it), put in IPEVT. Also, choose a date range from which the error occurred. This may give you more insight into what is happening.

We’ve finally been able to duplicate our ip-phone reset issue in a test environment for the first time and have isolated the source of the problem to a POE power-recycle issue. (Below are the results)

Our 4620SW get their power from the Cisco 3560 servers and a trouble ticket has been opened up with Cisco to troubleshoot the issue on the routers.
