I got burned by my own lecture. Replace your surge supressor on a yearly basis. (Or if your line takes a hit from lightning)

My UPS died so I put the equipment that was on it into an old surge supressor. We had a short power interruption that created a spike. It took out my force feedback joystick and scrambled my "natural keyboard".

Cost of new surge suppressor rated for lightning protection (1500 joules)
$20

Cost of blown components
Joystick- $90
Keyboard- $30

One company I worked for replaced their supressors every year. They had a temporary trailer setup during construction with 21 PC's and 4 printers in it. The trailer had metal siding and took a lightning strike because it had been improperly grounded. The result was 21 surge supressors destroyed (some of them had the supression circuits melted!). Number of PC's and printers taken out- zero

They used supressors that averaged $20 a piece. The techs told me the $50 to $70 ones don't work any better. the only thing that works better is a UPS.

In my experience you probably want to put your UPS on a supressor of it's own if you are in a lightning prone area. I had a UPS take a lightning induced surge - the result was that the UPS fried and the electrical overload caused the batteries to crack and ignite. Battery fires are ugly. The outcome was one switch and 2 servers destroyed by fire... not electricity. A suppresor in line in front of the UPS would have prevented this.

BTW - this was an APC UPS - generally excellent in design and manufacture. From what I have heard they have redisgned the units they had that were potentially vulnerable to this type of thing... but still, you never know.
