Losing connectivity to PC's behind 7945

I have some 7945's that register to CUCM 8.5.x.

The reg fine and pc behind commicates without issue.

Strange thing is after a certain amount of time, the PC seems to lose connectivity after a few hours or few days.

The PC was and is fine without the 7945 inline.

Using Brocade FCX648_HPOE

Strange thing is I have 6941's working fine at that site and have replaced the 7945's with multiple new known working phones.

Any idea's?

Update phone firmware.

If still trouble, you will need to look at the third-party switch.

Mark,

Is it happing only with Cisco 7945 Phones or all the phones in your organization? If its with only 7945 Model phones try factory default setting on the phone

Hi Mark,

1>  try swapping the phone & try changing the cable.

2>  Factory reset the phone.
