Dual RJ45 1000 Mbps adapter

The Lenovo 7ZT7A00544 adds two Gigabit Ethernet ports to a compatible ThinkSystem server through a dedicated LOM slot. It targets administrators who need extra wired links for virtualisation, storage traffic or management networks without occupying a PCIe slot.

Tool-less LOM insertion

The card slides into the proprietary LOM bay and secures with the server's built-in latch, so no screws or brackets are required. The only common issue is attempting installation in a system that lacks the matching LOM connector or running the ports without a linked switch port, which leaves the interfaces down.

Two 1 Gb links for typical LAN loads

Each RJ45 port negotiates up to 1000 megabits per second, providing enough headroom for general server traffic, iSCSI boot or backup streams. Saturation occurs when sustained throughput approaches the combined 2 Gbps ceiling, at which point a 10 GbE or 25 GbE adapter becomes necessary.

Questions about this item

How can I verify the 1000 Mbps link is active on the 7ZT7A00544 after installation?

Check the link LED on each RJ45 port; a steady green light indicates a 1000 Mbps connection, then confirm the adapter shows 1 Gbps in the OS network settings.

What comes with the ThinkSystem 1GB 2-port RJ45 LOM and what must I source separately?

The card itself is supplied; you will need a compatible low-profile or full-height bracket, two Cat5e or better Ethernet cables, and an available PCIe slot in the host system.

Which Lenovo 7ZT7A00544 variant should I choose for a standard 1 GbE dual-port upgrade?

The 7ZT7A00544 is a single SKU providing two RJ45 ports at 1000 Mbps; select it when you need a dual-port copper Ethernet adapter for a ThinkSystem server.
