Battery Back Up with Surge ProtectionEdit

Retrieved from ISED-L list-serv 2/09, CC3.0 a, s-a, nc license

We've had power problems on our campus for years. For some unknown reason, the area our campus (Nashville, TN) is in is incredibly prone to lightning strikes. We blow a 2-3 power supplies each month (+300 computers).

I talked to the electrical contractor I deal with, and he suggested getting a little tester to test the outlets when power supplies blow. It's not unheard of to have grounds wired incorrectly. So I found a $4 tester. If we find wiring problems, we have them corrected.

I asked about some kind of campus-wide protection and he steered me away from it due to cost and complexity. He suggested going with a APC Back-UPS ES series (or similar) unit for each computer, and that would do the trick. It's just enough to protect them through a surge if we have a lightning strike.

Our machines that are on those units seem to do fine, it's the other ones that have problems. So I'm steadily trying to bring in more of the ES series units.
