7937 Keeps restarting

Hi, I am having a little problem with both of my new 7937 conference phones. When I plugged them in first time, they've started ok and upgraded to the latest firmware which is 1.4.4. Then as soon as I add them to the CCME, they just start to reboot just after they get an IP address.

Now if I remove the phone(s) from CCME, then they do not do that. Strange?! .

The system I am using them on is a UC540 with a ESW520 switch. I have tried them both on a 2801 router with a Catalyst Express 500 switch and works fine.

Any ideas?

Your issue seems to be related to Power over Ethernet

Thanks, I've seen that but I thought my problem may be different. Do these not work on an ESW520-8P switches?
