This string holds the intId — an internal identifier UCS Manager's capability-catalog engine uses to reference the definition record for one built-in (onboard) component — such as an embedded LOM NIC or storage controller — soldered onto a specific server model's system board — distinct from any customer-facing name. intId is mainly for UCS Manager's own internal bookkeeping rather than something an admin types in directly, but it becomes the key to hand over when working with a Cisco TAC engineer confirming exactly which onboard-device definition a support case is actually referencing. A value like 'OBD-0231' as the intId would be Cisco's internal catalog key for this specific entry, not something displayed under a friendly name in the UCS Manager GUI.
