What is hcxUpstreamSerialNumber?
This read-only DisplayString of up to 16 characters holds the RX card's serial number, returning an empty string when the card is missing from the slot. It gives an admin a way to track hardware inventory and warranty/RMA information for each installed card via SNMP rather than reading a physical label. For example, when opening an RMA case for a failed RX card, the admin records the value of hcxUpstreamSerialNumber pulled remotely before the card is shipped back.
