[Nut-upsdev] Liebert ESP II driver

[Robert Jobbagy]

Hi all!

I read this in the shutdown.txt:

Here are the steps that occur when a critical power event happens:

1. The UPS goes on battery

2. The UPS reaches low battery (a "critical" UPS)

3. The upsmon master notices and sets "FSD" - the "forced shutdown"
   flag to tell all slave systems that it will soon power down the load.


But If I use my ups with nut on Battery when UPS don't send LB event just do
Output OFF and kill PC and after itself.

I don't understand when or why called the upsdrv_shutdown function?

Please someone tell me what happens if UPS works on battery and I use NUT.

Thanks your advice.
