Eaton's Network-M2 management card is the SNMP path for Eaton 9PX, 9SX and BladeUPS lines.
In the Network-M2 web interface, go to Configuration > Network > SNMP. Newer firmware ships with SNMPv1 disabled by default and only SNMPv3 available out of the box.
Prefer creating an SNMPv3 user with authentication and privacy set; only fall back to enabling SNMPv1 if your environment specifically requires it.
Eaton's MIB reports the same core fields as APC's — load, runtime, battery status, input/output voltage — under a different OID tree, which Linivo's Eaton profile maps automatically.
