    If the fans are still running, it's not power.  If the thing is
entirely powered off after the "beep" try another outlet.  If you're
plugged into a UPS, plug it directly into the wall; I had a wonky UPS
cause a very similar condition on my Netra NFS a number of years ago,
and that's an Ultra-1 under the covers.

    If you have an original Sun keyboard, sometimes the POST will
light up some LEDs on the keyboard and leave some dark; that will
yield clues that can be looked up or asked for here.

    If the machines were OK when you powered them down last, and they
haven't seen power for quite a while, try reseating the memory modules,
especially if the machines have been stored in a location that goes
from warm to cold.

    Just some ideas to try.
