September 29, 20241 yr Hi I have a APC Back-UPS BX1600MI connected to my UNRAID server via USB. I got an alert and that my Batteries have failed and the ups was beeping. The UPS was under warranty still and I got it replaced and it's now showing online and there are no alerts on the ups. The problem is UNRAID is still sending me alerts "Emergency! Batteries have failed on UPS Tower. Change them NOW" how do I stop this or reset the alerts? UNRAID Version: 6.12.13 Edited October 1, 20241 yr by Clayto Marked (SOLVED) in title

September 29, 20241 yr Community Expert Was the entire UPS replaced, or just the batteries? When I replaced the battery on my APC UPS, I continued to get messages from Unraid and Runtime Left still reported only a few minutes (when actually was 30+ minutes). I needed to connect the UPS to a Windows machine so I could run the APC PowerChute program to reset the battery replacement date. Everything cleared up after that. https://www.apc.com/us/en/faqs/FA408884/
September 29, 20241 yr Solution This is a common firmware-related problem with the APC BX series and `apcupsd` (Unraid's UPS Settings). The only solution at the moment is to use the NUT plugin with the `preview (latest build)` backend configured... ... and these additional settings added to the end (on line 9 or later) of `UPS.CONF` using the GUI configuration editor: pollonly lbrb_log_delay_sec = 3 lbrb_log_delay_without_calibrating The backend itself can be changed inside `NUT Settings` and requires a plugin reinstallation or system reboot after the change.

The UPS was replaced as the battery is not user-replaceable. 13 hours ago, Rysz said: This is a common firmware-related problem with the APC BX series and `apcupsd` (Unraid's UPS Settings).

I'll look into the plugin and see if I can get the fix working.

If it wasn't under warranty I would have recommended experimental surgery, depending on the user's level of hardware tech experience.
October 9, 20241 yr I've never had an APC last more than 2 years. I've been through 6 of them. 4 units, 1 replaced twice at Costco. Seems like they're engineered to fail. I've still got them (batteryless) kicking around here but don't yet know what to do about bringing UPS back online for my rack.

Is this still the solution to these error messages?

When changing to yes a lot of options disappear from the GUI, that's why I am asking. Also, can I use Peanut (https://github.com/Brandawg93/PeaNUT) together with the NUT instance and show it on my Homepage instance? Or do you recommend anything else?

February 4Feb 4 Community Expert So I've installed the NUT plugin, set Enable Manual Configuration to "for UPS Driver", and added pollonlylbrb_log_delay_sec = 3lbrb_log_delay_without_calibratingto the conf at the bottom of the plugin page (and disabled Unraid's default APC daemon). But the plugin still shows "Active Alarm(s) - On Line - Replace Battery". Im using version "default (2.8.4 stable)". Do I still need to use the "preview (latest build)"?
