[Bioclusters] How do people deal with temperature excursions (A/C failures)?

Our lab has a homebrew ROCKS cluster in small computer room that relies on
a single air conditioner. My experience has been that the poweroff(8)
command can't be trusted, so you often end up having to turn off the power
manually.  We had hardware damage when the A/C tripped the circuit breaker
recently.  Now we want to add another cluster and a file server so I'm
anxious to have a reliable way to shut systems down when they get too
warm.  How do other labs deal with this problem?
