How to install Lenovo ThinkSystem Broadcom 5719 1GbE RJ45 4-Port OCP Ethernet Adapter

Installing the Lenovo ThinkSystem Broadcom 5719 1GbE RJ45 4-Port OCP Ethernet Adapter is a straightforward process that fits into the streamlined lifecycle of Lenovo ThinkSystem servers. Follow these steps to ensure proper seating, power, and configuration:

• Power down the server completely and disconnect all power sources. Ground yourself to prevent static discharge inside the chassis.
• Open the server chassis and locate the OCP (Open Compute Project) slot designated for network adapters. Remove any blanking plate or filler present in the slot.
• Align the adapter with the slot carefully, ensuring the connector fits snugly into the PCIe interface. Gently press until the card is firmly seated and remains secure in place. If the chassis provides a retention screw, secure the card with the appropriate screw.
• Close the chassis, reconnect power, and boot the server. Enter the operating system to verify detection of the new NIC. The card should appear as a recognized network device in the OS networking stack.
• Install the appropriate drivers and firmware from Lenovo support resources. After installation, configure the NIC(s) in the OS as needed—set up NIC teaming, VLANs, and any required boot options (PXE) for bare-metal deployment. Validate network connectivity by testing reachability, bandwidth, and VLAN isolation as per your environment’s standards.
