Module: ENVIRONMENT-MIB
OID (symbolic): ENVIRONMENT-MIB::nnenvFanState
OID (numeric): 1.3.6.1.4.1.562.73.1.1.1.3.1.2.1.2
Node type: OBJECT-TYPE
Type: EnvState
Access: read-only
Description: The current state of fan 0, normal/fail.
What is nnenvFanState?
This read-only object reports the operational state, normal or fail, of the fan identified by the corresponding nnenvFanUnitIndex. Admins monitor it for early warning of cooling failures, since a failed fan increases the risk of the chassis overheating and forces reliance on the remaining fan, if any. A transition of nnenvFanState from normal(1) to fail(2) on fan index 0 would typically trigger an alert prompting a physical fan replacement.
