HPE dual-port 10Gb Base-T network adapter with metal bracket

HPE

HPE P26253B21 Broadcom BCM57416 10Gb 2-Port Base-T network card

SKU CH-5BXJ-704PF MPN P26253B21

Adds two 10 Gb Base-T ports with RDMA offload and signed-firmware security for HPE Gen10 Plus servers

  • Dual 10Gb ports handle heavy traffic loads
  • Two Base-T ports connect directly to copper infrastructure
  • Broadcom BCM57416 controller offloads I/O to free CPU cycles
  • Signed firmware validation blocks unauthorised code on the adapter
  • Scales across 1 10 25 100 200 Gb environments for future growth

HPE Broadcom 10Gb 2-Port Base-T adapter

The HPE P26253B21 adds two 10Gb Ethernet ports to compatible HPE Gen10 Plus servers using a Broadcom BCM57416 controller. It is built for data centres that need higher throughput for hybrid cloud, mobile data and streaming video workloads. The card reduces CPU load with I/O offloads including RDMA and tunneling. Signed firmware authentication helps prevent rogue firmware installation.

Suited for HPE Gen10 Plus server upgrades.

This adapter targets administrators expanding 10Gb connectivity inside qualified HPE Gen10 Plus systems where firmware trust and offload support matter. Buyers deploying white-box servers, older HPE generations or workstations without validated support should look elsewhere. The design assumes integration with HPE networking ecosystem components such as switches and transceivers. Environments requiring fibre or 25Gb speeds need a different model.

Dual-port 10Gb Base-T throughput

The decisive specification is the two 10Gb Base-T ports supplied by the Broadcom BCM57416 controller. This density and speed combination determines whether the card matches the uplink capacity and cabling plan of the target rack. If the infrastructure calls for single-port, fibre or higher-speed interfaces, this part will not fit the requirement.

Highlights

  • Dual 10Gb ports handle heavy traffic loads
  • Two Base-T ports connect directly to copper infrastructure
  • Broadcom BCM57416 controller offloads I/O to free CPU cycles
  • Signed firmware validation blocks unauthorised code on the adapter
  • Scales across 1 10 25 100 200 Gb environments for future growth

Questions about this item

What bandwidth does the 10Gb Base-T interface on the P26253B21 actually cap at?

The adapter provides two 10Gb Base-T ports; each port negotiates up to 10 Gb/s over copper cabling.

What slot and bracket does the P26253B21 need to fit in an HPE Gen10 Plus server?

It installs in a standard PCIe slot and uses the low-profile bracket supplied with HPE Gen10 Plus adapters.

How is the P26253B21 installed, and which step is often missed?

Power down the server, insert the card into an available PCIe slot, secure the bracket screw, then attach the Base-T cables; the step often missed is applying the signed firmware update before first use.
