We use all APC UPS'es here... every box is hooked up via one. About 20 all around I suppose in various sizes, the oldest are about 3-4 years old. We just had 3 fail this year (the first we've ever had fail). None gave any warning, including the largest (a 1250)... I'm a bit concerned also. (All the older ones weren't "smart", so all we have to depend on is the alarm lights and buzzers). -Chris (remove nospam) Bartram
