I need to expand this system to 80 digital ports, but when I replace the 2 DPM8's with 2 DPM16's, none of the extensions work on either of the 2 DPM16's. As soon as I plug a phone in, the buttons will light up for a moment. There is nothing in the display.

Funny thing is it recognizes the boards when I cold start the system, but none of the ports work...plug a phone in to any port on the 2 DPM16 boards in the expansion cabinet it will light up momentarily and then go dead. Do you thing I have a power supply problem?

Since the DPM8 boards worked and the DPM16 boards didn't (in the old cabinet, I'd say that it was probably a bad power supply in the old cabinet. Last edited by Splat; 07/22/13 01:34 PM.
