This article provides the SNMP MIB OID used to check the available PSUs on SRX devices.

To monitor the number of available PSUs on SRX devices using SNMP, use the MIB OID jnxPsuAvailableDeviceCount.

You can verify the value using the following operational command:

root@SRX> show snmp mib walk jnxPsuAvailableDeviceCount
jnxPsuAvailableDeviceCount.0 = 1

In this example, the output indicates that 1 PSU is currently available on the device.
