Lenovo Ethernet 4 Port Server Adapter I340-T4 49Y4240 | PCIe Server

Add four independent Gigabit Ethernet connections to a single server slot and simplify how you build out dense infrastructure. The Lenovo Ethernet 4 Port Server Adapter I340-T4 is designed for environments where port count matters as much as slot efficiency, giving you more network paths without consuming additional expansion space. This adapter is a strong fit for virtualization hosts, service nodes, and systems that need separate traffic lanes for management, storage, backup, or application workloads. By consolidating connectivity into one adapter, it helps reduce cabling complexity and preserves valuable PCIe resources for other hardware. For procurement teams, the value is straightforward: fewer add-in cards to source, install, and support, while still meeting the connectivity demands of multi-network server designs. For infrastructure teams, the benefit is operational clarity—more ports in a compact footprint, with the flexibility to map traffic the way your environment requires. Use it where reliable wired Ethernet access and efficient server design are priorities. In mixed workload racks, edge servers, and enterprise systems with limited expansion room, this adapter helps keep the network side of the build clean, organized, and ready for scale.
