Detailed Specifications
HPE P51179-B212 1GbE 4-Port BASE-T Network Adapter
Overview
The HPE P51179-B21 is a quad-port 1 Gigabit Ethernet (1 Gb/s) BASE-T network adapter tailored for HPE ProLiant servers. It uses four RJ-45 ports and supports 10/100/1000 Mb/s operation, making it suitable for standard server uplinks, virtualisation traffic or management networks. The card is based on a Broadcom BCM5719 chipset and uses an OCP3 (Open Compute Project) card form factor, enabling low-profile installation in dense rack servers. Designed for enterprise use, it supports VLAN tagging, IPv4/IPv6 dual stack, PXE boot and receive-side scaling (RSS). It installs into a server's OCP3 slot or compatible expansion slot and is appropriate for general-purpose server connectivity needs rather than high-speed uplinks.
Key Features

Broadcom BCM5719 chipset with offload support (RSS, TSO)
OCP3 form-factor card for space-efficient server deployment
Supports IPv4/IPv6, PXE boot, VLAN tagging and trust-firmware readiness
