Readynas OS 6 + Eaton network card M3
Hello everyone,
I've changed my UPS and added an Eaton 9130 + the last version of their network card which is the M3 revision.
But from every thread I've read on this forum and from the answers Grok gave me, it's impossible to make them working together in SNMP (public or private community).
Each time I'm getting the error "error in during post proc"...
Here is what Grok told me:
With a modern Network-M3 card, this is almost always the cause:
The “Eaton Powerware (Managed)” or “Eaton Powerware (Monitored)” MIB is designed for older Eaton/Powerware cards (Network-MS, ConnectUPS, etc.).
The Network-M3 does not implement this old proprietary MIB. It uses the standard RFC-1628 (IETF UPS MIB) MIB + a few additional Eaton OIDs.
As a result, when the ReadyNAS selects the Eaton MIB, it tries to access OIDs that do not exist on the M3 → failure during post-processing → this exact error.
The Network-M3 card (Gigabit Network Card) exposes only:
- The standard IETF UPS MIB (RFC 1628)
- The modern proprietary Eaton MIB xUPS-MIB (root OID 1.3.6.1.4.1.534.1 with numerous objects under .6 or .8, etc.)
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.
and the solution it's suggesting:
The solution that works (confirmed on 9130 + M3 + ReadyNAS OS 6)
- Community → public (read-only)
- MIB → Eaton Powerware (Monitored)
It passes post-processing without error, the status is displayed perfectly (battery %, time remaining, charge, voltages, etc.), and most importantly, the automatic shutdown of the NAS works perfectly (tested by dozens of users with exactly your hardware).
Monitored mode does not attempt the advanced commands (SET) that Managed mode attempts → no missing OIDs → no errors.
You only lose very rare functions such as:
- Commanding the UPS to shut down from the NAS after shutdown
- Controlling individual outlet groups (if your 9130 has them)
But for 99.9% of home/pro uses, it's perfectly sufficient and ultra-stable.
But I'm getting the same error each time whereas the I've configured the correct IP address in the firewall section of the M3 card.
Does anyone have a solution between these two devices?

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...
While you may not like it, a solution I guarantee is to ditch the Network Card M3 and put in a Network Card MS. I have exactly that configuration, and it works great. A seller on eBay currently has them for $30, so I bought a spare. Unless you have a switch that won't handle the max 100Mbps of that card, you don't need Gigabit Ethernet for simple UPS monitoring, anyway.
From what I have read, the M3 with current firmware requires SNMPv3, which is encrypted, though the data sheet shows it supports V1. I suspect that the ReadyNAS lacks the proper protocol and/or encryption capability for V3 within it's custom NUT instance due to its age. I do not know if there is an older version of the Network Card M3 firmware that will allow older SNMP or if you simply need to go into the control interface via HTTPS and enable SNMP V1. That's a question for an Eaton forum.
Netgear has never explained the difference between the "Powerware" and "Powerware (monitored)" selections. It has always been my ASSUMPTION that the "monitored" version gets it's information from an instance of Eaton IPM running on another device (i.e., from a separate "monitor"), not directly from the UPS. That may be how it's working for others, or it may be a firmware/setting issue like I discussed above. With my Network Card MS, the "Powerware" setting works and no separate monitor is required.
