4402 DS port no lights?

my 4402 has been working flawlessly for the past 6 years. Today, I remotely reboot the controller but never saw it come back online. When I got to the office, all looks normal, but I'm not getting any link lights on the DS port. I pulled the GLC-T module out and tested the other unused DS port with no success.

The controller has a steady PS2 lights and no other fault light. Does it sound like my module is shot? This is controlling 11 AP's and is critical for me to get it up and running ASAP.

You need to console into the WLC and see if its up or if you see anything wrong. If you swapped out glc-t with a good known one, then that would eliminate the glc-t.

4402 DS port no lights?

the current module I have in there calls for a ABCU-5710RZ-CS2 but it's currently discontinued.

I supposed any 1000Base-T SFP would work?
