HPE Broadcom BCM5719 Ethernet 1Gb 4-port BASE-T OCP3 Adapter

HPE

HPE P51181B21 network switch

SKU CH-R6WG-07621 MPN P51181B21

A four-port 1 Gb Ethernet adapter using a Broadcom BCM5719 controller for HPE Gen10 Plus servers

  • Four-port 1 Gb BASE-T connectivity expands server bandwidth
  • Broadcom BCM5719 controller delivers reliable Ethernet performance
  • OCP 3.0 form factor fits HPE Gen10 Plus server slots
  • Scalable adapter supports hybrid cloud and streaming workloads
  • Seamless integration with HPE networking ecosystem components

Four-port 1 Gb Ethernet OCP 3 adapter

The HPE P51181B21 is a Broadcom BCM5719-based network card that adds four copper 1 Gb BASE-T ports through an OCP 3.0 slot. It is built for HPE Gen10 Plus servers and targets administrators who need additional wired connectivity in a standardised form factor. The adapter fits into the open compute project ecosystem used across HPE server lines.

Suited for Gen10 Plus server expansion

This card serves IT teams expanding network density on compatible HPE Gen10 Plus platforms where an OCP 3.0 bay is available. It does not suit environments that require 10 Gb or faster speeds, fibre interfaces, or servers lacking an OCP 3.0 connector. Buyers needing higher throughput or different media should evaluate other adapter models.

Four 1 Gb BASE-T ports on OCP 3.0

The decisive specification is the four 1 Gb BASE-T ports delivered through a single OCP 3.0 interface using the Broadcom BCM5719 controller. This port count and speed combination determines whether the adapter matches the cabling and bandwidth requirements of the target deployment.

Questions about this item

How often will the BCM5719 chipset on the P51181B21 need firmware updates?

Firmware for the BCM5719 is updated through HPE server management tools when new versions are released.

What throughput ceiling will the 1 Gb BASE-T ports hit first under constant load?

Each of the four ports tops out at 1 Gb/s, so sustained traffic saturates at that line rate.

How much extra heat does the four-port OCP3 adapter add when running all day?

The adapter draws modest power for 1 Gb operation; exact thermal output depends on the host server's airflow design.
