Tested with XCP-ng 8.2 and a CyberPower CPS1500AVR UPS.

Connect the included USB or serial cable to UPS.

We use the Local version for single servers with USB or serial cable connected UPSs.

wget https://dl4jz3rbrsfum.cloudfront.net/software/ppb470-linux-x86_x64.sh
chmod +x ppb470-linux-x86_x64.sh
./ppb470-linux-x86_x64.sh

Check that services started:

systemctl status ppbed.service
systemctl status ppbwd.service

http:<ip.of.linux.server>:3052 ==== Configuration ==== We don't want the server to shut down immediately upon power failure…we want to wait until the battery gets low before we actually run the shutdown command. Edit the PowerPanel configuration file: <file> vi /etc/pwrstatd.conf </file> And change: <file> powerfail-shutdown = no #we want to shut down the UPS when the battery gets low, not when the power fails shutdown-sustain = 200 #set this to a little longer than it takes to shut your server down lowbatt-threshold = 15 #don't run the battery completely dead </file> Restart the service: <file> /etc/init.d/pwrstatd restart </file> or <file> service pwrstatd restart </file> Commands that run upon power-fail and low-battery events are also specified in the /etc/pwrstatd.conf configuration file. By default, it specifies: <file> /etc/pwrstatd-powerfail.sh </file> and <file> /etc/pwrstatd-lowbatt.sh </file> ===== Testing ===== You may want to change the lowbatt-threshold to 90 so the box shuts down in the shortest time, then change it back when finished testing. <file> lowbatt-threshold = 90 service pwrstatd restart tail -f /var/log/pwrstatd.log </file> ===== XenServer ===== These settings are probably not ideal, but are a good start. I think the goal would be to confirm that all VMs are shut nown properly before issuing the shutdown command. Modifications to above for XenServer: <file> vi /etc/pwrstatd.conf </file> And change: <file> powerfail-shutdown = no #we want to shut down the UPS when the battery gets low, not when the power fails shutdown-sustain = 600 #set this to a little longer than it takes to shut down all VMs and your server lowbatt-threshold = 35 #don't run the battery completely dead and give time to shut down lowbatt-duration = 60 #allow the script to run for 60 seconds before the shutdown </file> <file> vi /etc/pwrstatd-lowbatt.sh </file> and append: <file> xe vm-shutdown power-state=running –multiple </file>
