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?
