Intel 1340-T4 Quad Port Gigabit Ethernet PCIe 2.0 x4 Network Card

Quad-port Gigabit server adapter

The Intel 1340-T4 provides four Gigabit Ethernet ports over a single PCIe 2.0 x4 slot. It suits administrators who need dense copper connectivity for virtualised hosts, storage clusters or edge appliances. Both full-height and low-profile brackets are included for flexible chassis fitment. The card is new and carries the 49Y4242 part reference.

Sustained multi-queue throughput

Four independent MACs share the x4 lane, so concurrent 1 Gbit/s streams on all ports can be maintained without head-of-line blocking. Interrupt moderation and RSS distribute packet processing across host cores, keeping CPU utilisation steady during prolonged backup or replication windows. No single-port burst metric is quoted because the design targets balanced aggregate load.

Passive cooling in typical racks

The adapter runs without an onboard fan, relying on chassis airflow across its heatsink. Power draw stays within the PCIe slot budget, so auxiliary connectors are unnecessary. Acoustic contribution is negligible in server environments where system fans dominate. The 1.0 pound mass adds minimal mechanical stress to the motherboard slot.
