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.
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.
The default configuration of NUT, will keep your connected systems operational until a critical battery state is reached (ie battery is nearing exhaustion) and then power down your server/equipment in a controlled fashion. See http://www.networkupstools.org/

=Default Configuration (USB)=
Most USB connected UPS's will work with the default settings. If using a USB connection just enable nut as follows:
config setprop nut status enabled
config setprop nut status enabled
signal-event post-upgrade
signal-event post-upgrade
signal-event reboot
signal-event reboot
===Optional Configuration Options===
If your USB UPS does not work properly OR you have a '''serial device''' then follow the Configuration Options below.
=Configuration Options=
Not all UPS's are supported by USB or the newhidups driver, refer to: http://www.networkupstools.org/compat/stable.html to find the configuration details for your model of UPS.
For example Model bcmxcp_usb is for some Powerware units connected via USB or Model genericups for other Powerware units that only work on serial.
==Serial Connection==
'''Caution:''' ALWAYS use the serial cable supplied with the UPS. Standard serial cables won't work with a serial UPS and have been known to cause damage to the UPS.
The following are basic '''example''' settings. Replace the properties with the appropriate settings for your UPS:
config setprop nut Model apcsmart
config setprop nut Model genericups
config setprop nut Device /dev/ttyS0
config setprop nut Device /dev/ttyS0
config setprop nut Type 7
config setprop nut Type 7
config setprop nut status enabled
config setprop nut status enabled
Note: "Type" is only used if your model is Model genericups.
Check:
config show nut
config show nut
Apply changes and restart server:
signal-event post-upgrade ; signal-event reboot
signal-event post-upgrade
signal-event reboot
Alternatively, with NUT not running or a server reboot:
expand-template /etc/sysconfig/ups
expand-template /etc/sysconfig/ups
expand-template /etc/ups/*
expand-template /etc/ups/*
/etc/rc7.d/S38nut start
/etc/rc7.d/S38nut start
Confirm server is communicating with UPS:
upsc UPS@localhost
upsc UPS@localhost
For serial connected APC Smart UPS's there is a step by step How To: [http://wiki.contribs.org/APC_Serial_UPS APC_Serial_UPS]. This also shows how to configure the udev system instead of using a direct reference to the serial port.
Whenever a UPS event occurs Emails are sent to the admin account.
==Configuring as a slave==
Set configuration values:
config setprop nut SlaveUPS UPS@192.168.33.11
config setprop nut SlaveUPS UPS@192.168.33.11
config setprop nut Master no
config setprop nut Master no
Where 192.168.33.11 is your UPS master, that is the computer that is in direct communication with the UPS. The hostname of that computer may also work.
Apply changes and restart server:
signal-event post-upgrade
signal-event reboot
Confirm server is communicating with master:
upsc UPS@192.168.33.11
upsc UPS@192.168.33.11
==Conecting multiple UPS's==

=Aditional Information=
There are template fragments in /etc/e-smith/templates/etc/ups that control the config files located in /etc/ups. The default settings should be OK for most situations.
