Description: Eaton Automatic Transfer Switch (ATS2) MIB for monitoring transfer switch status, input sources, and load parameters.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is EATON-ATS2-MIB?

EATON-ATS2-MIB is Eaton's vendor-specific SNMP module for its Automatic Transfer Switch (ATS) product line, used in data center and facility power distribution to switch a load between two power sources. It exposes identity data (manufacturer, model, firmware version, serial and part number, agent version) alongside operational measurement and status objects covering input power sources and the current transfer/operation mode. Its core monitoring value is hardware/power status: it reports each input source's phase/dephasing condition through ats2InputTable/ats2InputEntry, the overall ats2OperationMode (which source is feeding the load), and general device status via the ats2Status group -- effectively a power-hardware health check rather than a compute/software one. It is a self-contained enterprise MIB but is typically deployed alongside standard power/UPS MIBs and monitored through general-purpose network management systems via SNMP. It is deployed in data centers, telecom facilities, and critical infrastructure sites where an ATS provides automatic failover between utility and backup power feeds. Engineers can download the EATON-ATS2-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EATON-ATS2-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • Eaton Automatic Transfer Switch (ATS2)

Monitoring Examples

An administrator polls ats2InputTable/ats2InputEntry to check ats2InputDephasing on each incoming power leg, catching a phase misalignment before it causes a failed transfer. Watching ats2OperationMode reveals whether the ATS is currently on the primary or backup source, and an unexpected mode change can indicate a utility power event. The ats2Ident objects (ats2IdentFWVersion, ats2IdentSerialNumber) are polled during audits to confirm firmware consistency and asset identity across a fleet of ATS units, while ats2Status/ats2Measure groups provide the general health and electrical measurements of the switch.

What Can Be Monitored

  • input source dephasing/status
  • active power source / transfer mode
  • firmware version
  • serial and part number
  • general device status
  • power measurements

How to Use in IPNetwork Monitor

Example using ats2InputDephasing OID:

Select an Eaton automatic transfer switch as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type ats2InputDephasing into the Find box to locate it in the OID tree, then select it and click OK. The dephasing in between Source 1 and Source 2. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value drifts significantly from its normal baseline, since an unexpected change often points to a real underlying issue. Click Finish to create the monitor; you can adjust any parameter later.
