EN12-45 POE Failure

Just wanted to see if anyone else out there has suffered from POE failure on Netron units (more specifically EN12-45s).

We have three, two of which have had POE fail at different points.

The EP2’s that we have which are also on POE haven’t had any issues.

The switches are Cisco 3750X’s.

I’ve contacted our distributor as well, but am still waiting to hear back.
