4-Port Gigabit Ethernet Card

This Lenovo ThinkServer I350-T4 card adds four RJ-45 network connections through a single PCI Express slot. It operates at 10/100/1000Base-T speeds over twisted-pair cabling. The plug-in card form factor is designed for server deployment.

Suited for Multi-Port Server Tasks

This adapter fits administrators who need four independent 1 Gbps links for virtualisation, traffic separation or link aggregation. It does not suit builds requiring 10 Gbps or faster throughput, nor systems without an available PCI Express slot. Buyers needing fibre connectivity should consider other options.

Four RJ-45 Ports on One Slot

The single specification that decides fit is the quad-port 1 Gbps RJ-45 interface on a PCI Express card. This density lets a server handle multiple network segments without consuming extra expansion slots. Verify the host has a compatible PCI Express slot before purchase.

Questions about this item

Should I pick the four-port version or a dual-port card for my server?

The I350-T4 provides four RJ-45 ports on a single plug-in card, so one slot handles four 10/100/1000Base-T links instead of occupying two slots with dual-port cards.

What does the 1 Gbps rating deliver inside a live server?

Each of the four ports negotiates up to 1000 Mbps full-duplex over twisted-pair cable, giving four independent gigabit paths for VM traffic, storage replication or backup streams.

Which PCI-Express generation does the card use and what bandwidth ceiling does that impose?

The card installs in a standard PCI-Express slot; the four 1 Gbps ports together need well under one lane of PCIe 2.0 bandwidth, so even older servers will not bottleneck the adapters.
