SmartUPS loses communication randomly, protected system sleeps randomly

[Anonymous user]

I have a UPS750 protecting a HP Proliant G6 server running windows 2008 SP2.

The UPS750 reports comms lost about 2-3 times a day.

About 2 time a month the server goes to sleep. The only think in the windows event log is a 'Kernal Power' event saying the system is going to sleep, no indication why

The first is just an annoyance, the second is a real problem. Anyone got any ideas?

Sorry I took a while to answer, other problems intervened. Recently this has been happening EVERY DAY.



is this while using the powerchute software or native Windows support only? Version: 8.0.1.609

if powerchute, which version? also, are you using USB or serial communications? i am guessing USB but would like to be sure. USB

does the system regain communication its own or do you have to do something to get it to start communicating again? on its own

how long has this been happening? how old is the UPS? 1 year and 1 year

Hi James,

Have you tried moving to PCBE 9.0.1? Also, what if you remove all the USB devices on your PC and just leave the APC UPS does the problem occur again?
