Disabling UPS beep under Linux

But it will take about 3-5 minutes to make all the setup under Linux properly. We need to run a upscmd at last, but there are a few steps before that.

• First of all, install nut package:

$ sudo apt install nut

• Append following lines to /etc/nut/ups.conf according to your ups device (descparameter not important, you don’t need to give correct brand name either but the given section name will be used later to identify configured ups device, we’re using eaton as config section name here):

[eaton]
driver = usbhid-ups
port = auto
desc = "Eaton 5E"

• Now start the upsdriver with upsdrvctl:

$ sudo upsdrvctl start
Network UPS Tools - UPS driver controller 2.7.4
Network UPS Tools - Generic HID driver 0.41 (2.7.4)
USB communication driver 0.33

• Run upsc command the get beeper status:

$ upsc eaton ups.beeper.status
enabled

• We’re so close, now append following lines to /etc/nut/upsd.users, change the username admin or password as you want:

[admin]
password = "test1234"
actions = SET
instcmds = ALL

• Reload upsd with the new users config:

$ sudo upsd -c reload

• You can query the list of the commands which will be supported by your ups device with the upscmd:

$ upscmd -l eaton
Instant commands supported on UPS [eaton]:

beeper.disable - Disable the UPS beeper
beeper.enable - Enable the UPS beeper
beeper.mute - Temporarily mute the UPS beeper
beeper.off - Obsolete (use beeper.disable or beeper.mute)
beeper.on - Obsolete (use beeper.enable)
load.off - Turn off the load immediately
load.off.delay - Turn off the load with a delay (seconds)
shutdown.stop - Stop a shutdown in progress

• As you can see, there is a command named beeper.disable and we’ll be execute this command (give the username and password which we configured just before):

$ upscmd eaton beeper.disable
Username (root): admin
Password: 
OK

• Now check the beeper status again:

$ upsc eaton ups.beeper.status
disabled

That’s it. It takes some time but your ears will be happy.
