The Lenovo 7ZT7A00549 is a four-port, 10 Gigabit Ethernet Base-T LAN on Motherboard (LOM) adapter for ThinkSystem servers, delivering high-performance connectivity and integrated management.
This 10Gb 4-port Base-T LOM is compatible with Lenovo ThinkSystem SR550, SR570, SR590, ST550 and SN550 servers when installed in the dedicated onboard LOM slot.
Key features include four RJ-45 10GBase-T ports, IEEE 802.3az Energy-Efficient Ethernet, hardware offloads for iSCSI and RDMA over Converged Ethernet (RoCE), plus integrated SFP+ bypass.
Each port supports 1GbE, 2.5GbE, 5GbE and 10GbE over standard Cat6a/Cat7 twisted-pair copper cables up to 100 meters.
Power down the server, open the chassis, slide the LOM into the onboard LOM connector, secure with the captive screw, then close the chassis and power on.
This adapter supports Windows Server, Red Hat Enterprise Linux (RHEL), SUSE Linux Enterprise Server (SLES), VMware ESXi and various Linux distributions with Lenovo driver support.

Integrated Management features include Wake-on-LAN, dual-port bypass, BIOS-level configuration and firmware updates via Lenovo XClarity Controller.
Yes, hardware offloads for iSCSI and RoCE significantly reduce CPU overhead and improve throughput for storage and HPC applications.
Use Lenovo XClarity or the Lenovo Service Processor to download and apply firmware updates automatically or manually with the Firmware Update Utility.
The card consumes up to 15W under full load and integrates with the server’s thermal management to maintain optimal operating temperatures.
Lenovo provides a one-year limited warranty, upgradeable to three or five years with Premier Support, including onsite repair and 24/7 hardware assistance.
Base-T uses standard copper cabling for lower cost and simpler deployment, while SFP+ offers longer reach with fiber optics but higher cable expenses.
Yes, the ports auto-negotiate speeds between 1GbE, 2.5GbE, 5GbE and 10GbE, allowing seamless connectivity to mixed-speed switches.
You’ll see up to tenfold bandwidth increases over 1GbE, lower latency, and enhanced virtualization and storage throughput for data-intensive workloads.
