Lenovo ThinkSystem 1Gb 4-Port RJ45 LOM Adapter 00YJ565 | Server NIC

Expand server connectivity with four 1 GbE RJ45 ports in a compact LOM form factor designed for compatible Lenovo ThinkSystem platforms. The 00YJ565 adapter gives infrastructure teams a practical way to add copper Ethernet interfaces without consuming a standard PCIe slot, helping preserve expansion capacity for storage, accelerator, or management cards. For environments that still depend on RJ45 switching, this adapter keeps deployment simple. It fits naturally into rack server builds where predictable wired access, familiar cabling, and easy serviceability matter more than unnecessary complexity. The four-port design also supports cleaner network segmentation and more flexible port assignment across workloads, management traffic, or redundant paths. This is the kind of component that earns its place in production infrastructure: compact, purpose-built, and aligned to the realities of enterprise server design. For teams standardizing on ThinkSystem hardware, it provides a cost-conscious way to extend network capability while maintaining the chassis layout and service profile expected in dense data center environments.
