What is the product type of SKU 811546-B21?

SKU 811546-B21 is an HPE Ethernet 1Gb 4-port 366T Adapter. The provided data classifies it as a network adapter and specifically as a PCIe Gigabit Ethernet adapter. It is also described as a quad-port 1GbE RJ-45 PCIe 2.x adapter, which identifies both the interface class and the port count.

How many network ports does this adapter have?

This adapter has four networking ports. The product data describes it as a 4-port adapter and a quad-port 1GbE RJ-45 PCIe 2.x adapter. For procurement and system planning, the verified port count is 4, which is the most important port-related specification provided.

What connector type is listed for the networking interfaces?

The networking interfaces are listed as RJ-45. The category description identifies the product as a quad-port 1GbE RJ-45 PCIe 2.x adapter, so the verified connector type is RJ-45 and the adapter provides four such ports. No other connector types are specified in the provided data.

What PCIe class is specified for this adapter?

The product is identified as a PCIe 2.x adapter. The category text states quad-port 1GbE RJ-45 PCIe 2.x adapter, and the structured product type is PCIe Gigabit Ethernet adapter. The provided data does not specify a deeper bus detail beyond the PCIe 2.x classification.

What Ethernet speed class is indicated?

The adapter is specified as 1GbE, or Gigabit Ethernet. The model name includes Ethernet 1Gb 4-port 366T Adapter, and the category also calls it a PCIe Gigabit Ethernet adapter. That gives buyers a clear verified speed class of 1GbE without adding any unsupported transfer-rate claims.
