8pre suddenly won't boot

I have an old MOTU 8pre Firewire I got on the cheap that was working great.  Been using it as an ADAT converter to add 8 channels to my 18i20.  Today I wanted to try reducing latency by increasing the sample rate to 48khz.  While fiddling with it I power cycled it and now after the "sparkle" animation it just displays the word "UP" on the LED display and outputs noise over optical and doesn't respond to pushing or turning the data knob.

What could "UP" mean?  Upgrade?  Underpowered?  Belly up?

It doesn't look as though anyone here has an answer to this. I've certainly never seen "UP" on an 8-pre display on the occasions I've had to use any of the MOTU interfaces that have "8-pre" in their name.

My guess is that the 8-pre internal firmware has got itself in a tangle, and you need to find a reset button or jumper to reset it to factory condition. Failing that, see if you can get a copy of the firmware from MOTU and re-load it into your interface.

Maybe that's why it was cheap...
