Via Redfish API the model and manufacturer are blank for a newly installed R730xd

We recently had a new PowerEdge R730xd installed in our lab and were wanting to retrieve some basic inventory and telemetry info via Redfish. From the snippet I trimmed below, there's plenty of useful data items but the "Model" is empty.

Has anyone else seen this behavior? Is there something we need to ask our lab support to configure in order for "Model" and "Manufacturer" to be populated?
