How to install Lenovo ThinkSystem DM Series 25Gb 2-Port Ethernet Card

• Power down the server, unplug it from power, and remove the chassis cover to access the PCIe slots.
• Identify an available PCIe slot that matches the card’s interface and length, then remove any securing screw or cover plate as needed.
• Gently insert the 2-Port 25GbE NIC into the selected PCIe slot until it is firmly seated, then secure the card with the chassis screw.
• Attach the appropriate network transceivers or cables for your topology (ethernet or Fiber/SFP28, depending on your network design) and ensure proper cable routing for airflow.
• Power on the server and install the latest drivers and firmware from Lenovo’s support portal or your OS vendor’s repository; reboot if required.
• Configure the NIC in your operating system or hypervisor (assign IPs, set up VLANs, enable SR-IOV or NIC teaming as needed) and verify connectivity with a basic network test or throughput measurement.
