How many network ports does the HPE FlexFabric 533FLR-T adapter provide?

According to the product category description, the HPE FlexFabric 10Gb 2-port 533FLR-T Adapter is a dual-port 10GBASE-T RJ-45 FLR-T Adapter. This means it offers two network ports intended for 10 Gigabit Ethernet connectivity. The dual-port configuration allows a single adapter to support multiple Ethernet links from one server.

What Ethernet speed class is supported by this adapter?

The adapter is classified under the 10GbE PCIe Network Adapter category, and its name specifies HPE FlexFabric 10Gb 2-port 533FLR-T Adapter. This indicates it is designed for 10 Gigabit Ethernet operation on both ports. The category and product naming both emphasize that it is intended for 10GbE connectivity rather than lower speed classes.

What interface type does the 533FLR-T adapter use for network connectivity?

The adapter is categorized as a Dual-port 10GBASE-T RJ-45 FLR-T Adapter. This means the network interfaces use 10GBASE-T technology with RJ-45 connectors. This classification shows that it is intended for copper-based 10 Gigabit Ethernet connections using standard RJ-45 ports rather than fiber or other media types.

How can procurement teams uniquely identify this HPE network adapter?

Procurement teams can identify this adapter by its SKU 867331-B21 and full model name HPE FlexFabric 10Gb 2-port 533FLR-T Adapter. It is also categorized as a Network Adapter, 10GbE PCIe Network Adapter, and Dual-port 10GBASE-T RJ-45 FLR-T Adapter. Using the SKU together with the model name helps ensure accurate ordering and configuration tracking.

Product overview

The HPE FlexFabric 10Gb 2-port 533FLR-T Adapter, SKU 867331-B21, is a dual-port 10GbE network adapter designed for environments that require 10 Gigabit Ethernet connectivity. As a 10GbE PCIe network adapter in an FLR-T form factor, it is suitable for deployments needing two 10GBASE-T RJ-45 ports within a flexible LAN on motherboard configuration. This adapter fits into scenarios where dual-port 10GbE connections are required for server or network integration and can be evaluated primarily on its port density and 10GbE capability. The product falls under the 10GbE PCIe Network Adapter category, specifically as a dual-port 10GBASE-T RJ-45 FLR-T Adapter. Procurement teams can standardize around this model when planning consistent 10GbE copper connectivity. All functional planning, including performance expectations and power considerations, should be based on the dual 10GbE port design and the FLR-T adapter format.
