Lenovo IBM 1Gb Quad-Port PCIe2 x4 Ethernet-TX Adapter | Enterprise NIC

Add four wired network connections from a single expansion slot and keep server I/O simple. The Lenovo DCG Sourcing IBM 1Gb Quad-Port PCIe2 x4 Ethernet-TX Adapter is designed for infrastructure teams that need more copper ports per system without moving to higher-cost uplink tiers. With four 1 GbE Ethernet-TX ports and a PCIe 2.0 x4 host interface, this adapter fits access-layer servers, virtualization hosts, and appliances that benefit from separate traffic paths for management, storage, and application workloads. The quad-port design helps reduce port congestion on the motherboard while preserving valuable PCIe resources for other cards. This is the kind of adapter chosen when consistency matters more than headline speed. It gives you predictable 1 GbE connectivity, straightforward copper cabling, and a compact footprint that works well in dense rack deployments. For teams standardizing on proven server networking, it offers a practical way to scale port count without overbuilding the network stack.
