Mitel 5310 Conference Unit

[MitelGuy57201]

I have a 5310 conferencing unit that is attached to a 5224 IP phone. The top green LED on the side control unit is flashing and the conferencing unit is not working.

Up until last week, all was well. The connections have all been reseated. Still no luck.

Any clues as to where to begin?

Thanks in advance!

Is external power adaptor working?

Good call. I had checked to make sure everything had power - and it did. Funny story... the guy had an electronic picture viewing frame on his desk - seems the power adapters had "somehow" been switched not giving the side control unit the 24 VDC that was needed - it was only getting 12 VDC. Thanks again!
