> I use a Smart UPS 1400 from APC with the managmend card AP9617 > see http://www.apc.com/resource/include/techspec_index.cfm?base_sku=AP9617 > -- Thanks for the information. Questions: 1. Does this model come with software for Linux system -- unattendant shutdown/startup? 2. I just want one for one linux system, do I still need the managmend card? What's the use of th card for you? Thank you! Hongwei
