What is chassisFruSerial?

This OCTET STRING is the FRU serial number of the chassis, a value unique to this one physical unit rather than shared by every unit of that part number. An admin records it on an RMA or support case so the vendor can trace warranty status and failure history for this specific physical item, not just its model. For example, chassisFruSerial is the value an admin reads off to open a vendor support ticket about a specific misbehaving chassis, distinct from every other chassis of the same model in the data center.
