I believe that the APC Symmetra line does on-line double-conversion. This is the route that we are moving in the future due, not only to the on-line functionality, but also because of the module-based layout (add more kVA later), redundancy and hot-swappable batteries.

The APC units are "Standby" (equipment runs on line power and quickly switches to inverter when needed) UPS. Not that I have had any real issues with them I like the Idea of "On-Line" UPS better where the UPS inverter is always supplying power to the equipment. They are also a little happier when connected to a back-up generator than Standby UPS units. CyberPower "Online Double Conversion" would be my recommendation. http://www.cyberpowersystems.com/products/ups-systems/ups-selector.html The software included allows for a single machine to connect via USB, then it will chain to any number of servers via software. So now if you have several servers on a single UPS all the servers can shut down gracefully in the event of a UPS low battery. I have a couple installed and have been very happy with them.

I was the tech at Pocahontas Area from the time of dirt up 2 1/2 years ago when I retired. I just got called back to the majors and am in need of some help! I would first of all like some new info on how to image groups of PC's (Sorry, Lance, nothing's changed at POKY!!!) I see we have a duplicator but I'm wondering about the latest and greatest for creating the image. Any help would be greatly appreciated. I'm using my retirement email address and will continue to do so. I'm trying to work myself out of a job ASAP. We are doing a 1 to 1 in our high school and will be implementing HP's DYKnow. Also, the footings for a new high school are in place. Not sure whether I'm coming or going. I will be asking for lots of advice, even from Lance!! George PS: We are also looking for a back-up ups system which we could purchase now and move into our new building. Anyone done any ups work lately???
