The consensus was the front panel power switch was stuck "on", or
the power supply had lost its mind and remembered its last state as
"on" and kept returning to it.

After an afternoon of parts swapping and head scratching, we finally
found the culprit was the KVM switch we had all forgotten was
in the circuit.  If the KVM was plugged into the keyboard port of
any of the 3 Ultra-60s we tried, the connected system would not
power off.  If a Sun keyboard was directly connected, no problems.

This KVM is one of several we have some the same brand, but it
has apparently gone off in the weeds and needs replaced.

Thanks to all for your rapid responses - you ROCK!
