I'm not sure about Output status 8. The MIB file v.5.0.1 from Sococmec 
does not clarify what is the "Output Source standby". The UPS we have 
never returns value 8.

I build the patched nut 2.6.3 RPM (it takes time to fight against old 
autoconf version in RHEL5, hehe...) and start it at servers connected to 
Socomec UPS. It works mainly, but we need to arrange some tests with UPS 
power off. Probaly we can do it on next week
