Suggestion 1: ->from the console<-, run
setterm --powersave off
That way, even if you connect a monitor (in our, uh, "computer labs", we
have a monitor-on-a-stick), you'll still see what's on the screen at the
end, not the power save blanking.

Um. Um. What make is the server? We had that on some new Suns, where after
working on them, the fans would spin up and *not* spin down to normal. The
answer to that was, after powering them down, pull all the plugs, and
leave them out for 20 sec or so....
