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.
