HPE 649871-001
(331T) Gigabit Ethernet Adapter 4‑Port
The HPE 649871‑001 (331T) Gigabit Ethernet Adapter is a refurbished quad‑port 1 GbE network card engineered for reliable server connectivity. Based on the Broadcom BCM5719 chipset, it delivers full line‑rate 1 Gbps speeds across four RJ‑45 copper ports. Suited for virtualization hosts, small‑scale data centers, and segmented network deployments, this adapter supports advanced offloading, teaming, and PXE boot features. Its low-profile PCIe Gen2 ×4 form‑factor fits HPE ProLiant Gen8–Gen10 servers, making it a cost-effective and dependable solution for enhancing server capacity and redundancy.
Features
This server-grade adapter delivers consistent gigabit performance across four independent copper ports using a Broadcom controller. Supporting protocols and features such as IEEE 802.3ad link aggregation (LACP), VLAN tagging, jumbo frames, and PXE boot, it offloads network tasks to reduce CPU load and latency. With support for energy-efficient Ethernet (IEEE 802.3az) and precision time protocol (IEEE 802.1as / 1588), it is optimized for modern virtualization and converged workloads. The card’s compatibility with ProLiant DL and ML series servers from Gen8 through Gen10 ensures seamless deployment in mixed HPE environments.
Advanced Options
Built for enterprise reliability, this adapter ensures steady performance even under heavy virtualized or I/O–intensive workloads. The Broadcom BCM5719 chipset is well supported across major OS platforms and hypervisors, including FreeBSD (via the bge driver)
