Module: CME-MIB
OID (symbolic): CME-MIB::chassisFanHardwareVpdUuid
OID (numeric): 1.3.6.1.4.1.2.3.51.2.2.21.13.1.1.8
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: Chassis fan hardware VPD UUID.
What is chassisFanHardwareVpdUuid?
This OCTET STRING is a UUID burned into a chassis cooling fan module's VPD at manufacture, a globally unique identifier for that physical unit. Management software uses this UUID, rather than a serial number a technician might mistype, to keep tracking the same physical card correctly across moves and VPD reloads. For example, management software tracks chassisFanHardwareVpdUuid so it continues correctly identifying a specific fan module even after the chassis's VPD table is reloaded.
