In Battery Backup (UPS)

Very easy to setup, easy digital display, setup with Nas4Free and Freenas was relatively painless

works as advertised. looks good and the display is easy to read without blinding you at knight.

I had previously bought a CyberPower CP1500AVR900W to support my substantial Home Theater System which was suffering problems with frequent power fluctuations from my rural electric service. It has solved all of those problems and even kept the entire system going during several brief power outages. I bought this less powerful but more fully-featured unit for my computer system. It seems to have no audible alarms but when it comes on an LCD display illuminates. Using a switch below the disply, you can toggle through the input voltage, the output voltage and hertz, a bar graph of the battery power and some other useful information. When the power goes out (I just pulled the plug for a test) the LCD display shows a bar graph of the battery power, a bar graph of the power load upon the unit and calculates the time it will continue to power those devices, which in my case was 33 minutes. I didn't load the shutdown software as I have time to do it myself.

Had the correct model and serial number as well as almost everything else except the number of battery quantity it needed to be four of instead of 1, even if the UPS was still about to completely fail after the end of the warranty.

This unit has worked well for over a year. I hooked it the serial port to the serial port to the system serial port. I down loaded the linux driver rpm file and as root did rpm -ivh <thefilename>.rpm. The installer found the serial port, setup the supply and inserted the required startup and shutdown scripts. Totally painless. When the power goes off, the unit backups (as expected) and sends a message stating that it's in action and will shutdown the system in some time period (which you choose). The command "upsm test" can be used to test the supply. The upsm system management command is located at /usr/sbin/upsm. You can get information about the device, test it, get logs and status. I have used several ups systems (mostly apc and exide). This one is IMO, the best one I've had. The hot swap battery capability (using standard batteries BTW) is really a plus.

This UPS replaced an APC Smart UPS 750 RM 2U - also a rackmount unit. The SRT1000RMXLA adds a super-functional display, power-conditioning capabilities in addition to larger battery capacity/improved runtime.
