[Nut-upsdev] HCL HP R5000 supported by bcmxcp

[Peter Tuhársky]

Hi, Arnaud

One thing bothers me. I don't see parameters like "battery.runtime.low" 
here. How will the UPS notice the NUT that it is running critically low? 
Or better said, when will it do that?

With APC, there is such parameter, default set to 120 seconds. As I 
understand, when battery goes critically low (2 minutes before getting 
fully discharged), it sends "battery critical" to the NUT server, and 
the NUT sends "shutdown" command to clients.

However with the HP, either R5000 or R5500, there is no such parameter, 
and I even didn't find it in web interface settings. There is quite 
opposite setting possible (custom): how many seconds AFTER the UPS goes 
battery, should it switch off. This is quite illogical, though.

So, I'm afraid a bit doing UPS fullscale test because I don't know, 
whether servers will have enough time to shutdown before UPS switches 
itself off. I know I will face it in future, however need more info now.
