PD Detection Fault Problem



We had a problem regarding PoE switchports which is tagged as PD Detection Fault, which causes our IP Phones not powering up.

I first tried connecting one (1) IP Phone at ethernet port to see if the phone is powering up on the port which does not have PD status and it powers up, then plugged it in at ethernet port which is tagged with PD the phone is not getting PoE.


The following is our Brocade switch details:
