What network category does this adapter belong to?

It is listed under Network Adapter, PCI Express Gigabit Ethernet Adapter, and Single-port 10/100/1000Base-T RJ-45 1 Gb/s. That means the adapter is classified as a PCIe Gigabit Ethernet device with copper RJ-45 connectivity.

How many ports are specified?

The provided category states that the adapter is single-port. No other port count is given in the source data, so the documented configuration should be treated as one network port only.

What Ethernet speed class is documented?

The source data specifies 10/100/1000Base-T and 1 Gb/s. This identifies the adapter as supporting Gigabit Ethernet in the documented category description, with the listed interface class covering copper Ethernet connectivity.

What connector type is listed?

The category includes RJ-45, which is the connector type named in the provided data. The adapter is therefore documented as a 10/100/1000Base-T RJ-45 network device.

Product overview

The HP NC320T PCI-E Multifunction Gigabit Server Adapter is a single-port network adapter in the PCI Express Gigabit Ethernet Adapter category. It is listed as a 10/100/1000Base-T RJ-45 1 Gb/s adapter, which identifies it for copper Ethernet connections and Gigabit-class network use. The product data ties the model to the NC320T name and the SKU 384088-B21. No additional performance figures, port counts beyond the single-port category, or interface details are provided in the supplied specifications. For procurement teams, this makes the documented specification set narrow and focused on basic adapter classification rather than extended feature disclosure. The available data is sufficient to identify the product family, interface class, and Ethernet speed class, but not to confirm unsupported attributes such as onboard features, driver support, or compatibility claims. Buyers should use only the listed category and product naming details when matching this adapter to server network requirements.
