Intel I340-T4 E1G44HT Quad Port RJ-45 x4 Gigabit Network Card

Intel I340-T4 Quad-Port Adapter

The Intel I340-T4 is a PCI Express network adapter that provides four independent RJ-45 Gigabit Ethernet ports from a single expansion slot. It is built for servers and workstations that need to connect to multiple wired networks or segment traffic across separate physical links without adding extra cards.

Replaces multi-card setups for density

A single I340-T4 replaces four single-port adapters, freeing PCIe slots and reducing cabling inside crowded chassis. The upgrade is worth it when a host needs more than two Gigabit links but has limited slot availability or when consolidating management interfaces onto one controller simplifies driver maintenance.

Sustained throughput across four ports

The integrated Intel 82580 controller handles concurrent traffic on all four ports at 1000 Mbps without the bottlenecks seen when multiple discrete adapters share a PCIe Gen 2.0 x4 lane budget. Wake-on-LAN remains active on every port during low-power states, allowing remote management traffic to pass continuously without waking the host processor.
