For a couple of months, my Transporter would spuriously reboot itself as
if it had lost power completely - relays clicking, logo scrolling, etc.

Not finding anything directly relevant through Google searches other
than a vague reference to the DC power supply being a cheap Chinese
switcher, I opened the cover and measured the PSU output - 5.1 V
unloaded, exactly what one might expect. However, plug in the front
panel, and the voltage dropped to 4.6 and wandered around between there
and 4.8-4.9 - the DC power supply was obviously hosed.

Searching around some more, I found  a UK company that sells a rebranded
version of the exact same board from Unifive. I'll post a link in a
follow-on message (since this is my first post to this forum, I can't
post it here)

Confident in the fix, I ordered two ($8 each, but $31 shipping from the
UK to US). A few days later, the new supplies arrived at my door. Put
one in and checked voltage - 5.1V unloaded and 5.1V with the front panel
plugged in.

The Transporter is back in the rack and I'm hoping to not hear the
dreaded clicking of a reboot.

Hopefully this will help someone with a similar problem or a completely
dead front panel - check the DC supply between the front panel and the
main board in the back, but be careful. The back connector is 110VAC
when plugged in. The front connector is 4 pins but only the outer two
are used.
