The NUT control software is installed at a few sites and can be used to directly control Cyberpower and UPSonic UPS.

The main use at the moment is to power cycle the DBBC3s at both Mt. Pleasant and Katherine.

Check Basic Setup

Ensure RfSwOnForS is turned ON at pduhb and ipske  for mixed mode observations AUM, AUA etc

Otherwise wide band mode is enabled, where symptoms include reported bad delays on IF's

TEMPORARY CHANGE (6/6/22) Please use the pduhb.phys.utas.edu.au internet power switch until further notice. The weather computer is currently offline.

To reboot DBBC3HB, use the following commands <code>ssh observer@weather su upscmd CyberPower load.off ### wait 10s upscmd CyberPower load.on </code> The upscmd will prompt for a username and password (admin and the root pw.)

Katherine

To reboot DBBC3KE, use the following commands

ssh observer@dell2ke
su
upscmd  UPS-DBBC3 load.off
### wait 10s
upscmd  UPS-DBBC3 load.on

The upscmd will prompt for a username and password (admin and the root pw.)

If you have error messages when running these commands, try killing any NUT processes (with pkill -9 nut) and then restart with /etc/init.d/nut-server start . If that doesn't kill the running nut command, then restart the nut server with “/etc/init.d/nut-server restart”

Installation

apt-get install nut

Then edit the /etc/nut/ files - vc0/flexbuffhb/dell2ke have templates for a working configuration

UPS interaction and control

To see the list of available commands, use

upscmd -l CyberPower

To switch the UPS off or on, use:

upscmd CyberPower load.off or upscmd -l CyberPower load.on

You will need to run this as root, using the admin username.
