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 signal-event post-upgrade signal-event reboot
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
The following are basic example settings. Replace the properties with the appropriate settings for your UPS:
config setprop nut Model genericups config setprop nut Device /dev/ttyS0 config setprop nut Type 7 config setprop nut status enabled
Note: "Type" is only used if your model is Model genericups.
Check:
config show nut
Apply changes and restart server:
signal-event post-upgrade signal-event reboot
Alternatively, with NUT not running or a server reboot:
expand-template /etc/sysconfig/ups expand-template /etc/ups/* /etc/rc7.d/S38nut start
Confirm server is communicating with UPS:
upsc UPS@localhost
For serial connected APC Smart UPS's there is a step by step HowTo on 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 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
Conecting multiple UPS's
To be added http://bugs.contribs.org/show_bug.cgi?id=629
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.
For information on configuration parameters:
man ups.conf man upsd.conf man upsd.users man upsmon.conf man upssched.conf
For general information:
man upsd man nutupsdrv
