This has not been my best week with my NEC installed equipment. I have a DS1000 that I installed about 9 months ago that worked great until now. The problem is now that it goes dead and my customer has to go the the ksu and reboot it. Then it works for a while and then does the same thing. When I called tech support, I told them that I had a grounded electrical surge protector, next layer is a voltage regulator (APC LE-1200) and final layer a Tripp-Lite UPS with surge protector. They told me to plug directly into the electrical outlet and the problem cleared up. I tried plugging back into the the UPS a few days later and let it stay like that for a few days...the problem reappeared immediately. Went back to direct electric, problem cleared. I have many DS1000 installed. All set up with the triple protection on the electric side. Same with the DSXs. On the CO side, I use ITW/Linx auto sneak protection fuses on the 66 block. I protect the systems in every way possible. Never a problem until now. Can someone illuminate me here? :bang: Al
