no problem...

Very well. You provided the patch yourself already :-)

I haven't tried that out yet... Didn't have the guts to temper with the
main switch on the wall yet 8-)

Na, I already run the pw mib... The ietf mib didn't even so more than a single 
imput phase... The above should be hidden inside the XUPS.mib I guess.

Agreed. But I would suggest to add PCAP, PRED or anything along those lines to 
the OL so one knows that we are running in parallel mode. I don't know whether
this status changes if the other UPS goes down for some reason. So it
would be handy if on could differentiate those.
