Module: CME-MIB
OID (symbolic): CME-MIB::chassisFanControllerVpdRevision
OID (numeric): 1.3.6.1.4.1.2.3.51.2.2.21.12.1.1.7
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: The revision of the chassis fan controller firmware.
What is chassisFanControllerVpdRevision?
This OCTET STRING is the firmware revision of the onboard controller chip on a chassis fan module, as distinct from the fan's separate hardware VPD data covering its manufacturer and serial number. An admin checks this revision before a firmware campaign to confirm whether a given fan's controller needs the update or already has it. For example, chassisFanControllerVpdRevision showing an older revision string on one fan while its neighbors show a newer string flags exactly which fan module still needs its controller firmware refreshed.
