Smartlink architectural control processor - no power?

Helping a friend out. They have a Smartlink ACP in a Unison DRd 120v, 12 dimmers, with one wall panel to control presets.  The Smartlink ACP suddenly appears to have no power, Thought the station power module does have one light on it for link power.

Flipped breakers, looked inside the modules, re seated everything, hit the reset button, nothing stood out, no changes.

Anyone had this problem before? Am I missing something obvious? Any thoughts?

Called tech support but they seem to be on a Monday to Friday schedule now.

  • Amazing thank you. I guess the voicemail said they'd get back on the next business day so I didn't bother, good to know. 

    This article is super helpful thank you! I had gone through most of these steps... Now I just have to find where the "test mode" switch is

  • Found it!

    Still no power. Seems like it might need repair 

  • For those following the thread and wondering, Test Mode is in the upper right.
