Hello, I have been using OpenUPS for my rack for at least 3 years without a single problem powering server + switch + media converter with 12VDC.
This is a DC-DC UPS meaning that it does not replicate a UPS that you simply plug in and it works. The reasons for me using OpenUPS are: -An open system, you chose all aspects of your system! -I can add as many batteries as I want. The OpenUPS is a 10A@12V device, but to it I have 80Ah 12V batteries connected meaning that even at 10A load I get about 7 hours of uptime, in reality I get about 30 hours after power out. -Efficient! Your computer consumes DC, your battery stores DC. Why convert to AC in between? -Programmable (through a windows application) for different battery charging modes meaning that you are even free to chose battery size, battery chemistry, fast and damaging charging or slow and healthy etc. For this you need a source of 12V and a supply for your computer from 12V - which my supermicro board already has built in. dmesg gives me the following: upd0 at uhidev2 and dotbit$ sysctl hw.sensors.upd0 hw.sensors.upd0.indicator0=Off (BatteryPresent), OK hw.sensors.upd0.indicator1=On (Charging), OK hw.sensors.upd0.indicator2=Off (Discharging), OK hw.sensors.upd0.indicator3=Off (NeedReplacement), OK hw.sensors.upd0.indicator4=Off (ShutdownImminent), OK hw.sensors.upd0.indicator5=On (ACPresent), OK hw.sensors.upd0.indicator6=Off (Overload), OK See: http://www.mini-box.com/OpenUPS?sc=8&category=981 Hope this helps!

It works like a charm. APC is quite expensive brand so I am looking for any cheaper alternatives. > > Thanks! > > -- > radek >
