Uninterruptable Power Supply
Nut UPS – Uninterruptable Power Supply
The primary goal of the Network UPS Tools (NUT) project is to provide reliable monitoring of UPS hardware and ensure safe shutdowns of the systems which are connected.
Default Configuration
Most USB UPS devices will work with the default settings. If your USB UPS does not work properly OR you have a serial device then follow the optional instructions below. If using USB just enable nut.
config setprop nut status enabled signal-event post-upgrade signal-event reboot
Optional Configuration Options
Not all UPS's are supported by USB or the newhidups driver, refer to the link below.
eg. config setprop nut Model bcmxcp_usb is for some Powerware units on USB.
Or config setprop nut Model genericups is for other Powerware units that only work on serial.
Find your Model here http://www.networkupstools.org/compat/stable.html
Note: "Type" is only used if your model is genericups
Caution: ALWAYS use the cable supplied with the UPS. Standard serial cables won't work with a serial UPS and have even been known to cause damage to the UPS.
These are basic example settings. Replace the properties with the appropriate settings for your UPS.
