Lenovo ThinkSystem Broadcom 5719 Network Adapter

Overview

The Lenovo 4XC7A08235 is an Ethernet network adapter designed for ThinkSystem servers with an Open Compute Project (OCP) mezzanine slot. It provides four RJ-45 ports capable of 10, 100, and 1000 Mbps speeds, delivering up to 1 Gbps per port. Built on the Broadcom BCM5719 controller, this adapter ensures reliable wired connectivity in dense server environments where consistent network throughput is essential.

Connecting via a PCI Express 2.0 x4 interface, it supports twisted pair cabling commonly used in Ethernet, Fast Ethernet, and Gigabit Ethernet networks. This makes it compatible with existing copper cabling infrastructure without requiring changes to switches or cables. The adapter supports TCP/IP protocols and IEEE 802.1Q VLAN tagging, allowing for standard IP network operation and traffic segmentation.

This network adapter is well suited for rack-mounted servers that require multiple dedicated network connections for management, application traffic, or isolated services. It is particularly useful in virtualization environments where separate physical network paths improve workload separation and performance. Compliance with global safety and electromagnetic standards makes it suitable for enterprise data centers with strict certification requirements.
