3.4 UPS

CMOS Setting

If using a UPS that cleanly powers off the muPBX when a power failure is detected, it will be necessary to change the CMOS setting in the muPBX to "After Power Failure = Power On" and NOT "After Power Failure = Last State" which is usually the default setting. Cleanly means the UPS performs some sort of shutdown, i.e., "shutdown -h now".
