What is hcxUpstreamHardwareVersion?
This read-only DisplayString of up to 16 characters reports the hardware revision of the RX card, and per the description it returns an empty string when no card is physically present in the slot. An admin uses it to confirm which hardware build is installed before applying a firmware update or troubleshooting a known hardware-revision bug. For example, before rolling out a boot ROM upgrade, staff poll hcxUpstreamHardwareVersion across all RX cards to identify which ones are an older revision that the update does not support.
