Readynas OS 6 + Eaton network card M3

I've bought the M3 network car because I had a really good deal about it and it's the most secure one in this category. It's compatible with SNMP v1,v2v & v3 but has Grok said "The old legacy Powerware MIB (the one that ReadyNAS expects for “Eaton Powerware”) was under the old tree 1.3.6.1.4.1.534 with objects directly under .1, .2, .3, .4, .5, etc. This MIB has been abandoned since the ConnectUPS-X / Network-MS cards (before 2015 approximately). The M3 no longer implements it at all in its SNMP agent." Unfortunately I didn't know that before buying it :/...

The monitored version of powerware just need read rights (public community is enough) whereas the managed version need write rights (so you need to activate private community). I think the simple "Powerware" is just a generic one...

Until now I'm using it in auto mode with USB connector, not perfect but kinda working.

I'll retry again with the USB connector unplugged and follow Grok instructions. I'll keep you informed. I've recently changed the PSU of this NAS by another Seasonic, it was toasted...
