Description: Machine chassis hardware revision. If a hardware revision is programmed in the OEM VPD area for this component, then the HardwareRevisionString version of this MIB object should be used.

What is chassisHardwareRevision?

This INTEGER is the numeric hardware revision level recorded for the chassis, falling back to the string-format HardwareRevisionString object whenever the OEM has programmed a revision into that string field instead. An admin polls this quick numeric value first when scripting a fleet-wide revision check, only decoding the string object if this one turns out to be unprogrammed or ambiguous. For example, an admin scripting a fleet audit might read chassisHardwareRevision to flag any chassis still on hardware revision 1 that predates a known backplane fix.
