tnEntSensorExtOperMode
Module: TN-ENTITY-SENSOR-MIB
OID (symbolic): TN-ENTITY-SENSOR-MIB::tnEntSensorExtOperMode
OID (numeric): 1.3.6.1.4.1.868.2.5.6.1.1.1.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This variable indicates operational mode of the power supply when redundant modules exists.
What is tnEntSensorExtOperMode?
This INTEGER reports whether a redundant power supply module is currently operating as master(1) or slave(2). Admins check this in dual-PSU setups to understand which module is actively driving the system and which is standing by, useful when diagnosing a failover event. For example, if a previously master(1) supply now reports slave(2) after a fault, that signals a failover to the other module occurred.
