LR-LINK LRES2217PT Dual-Port Gigabit Adapter

The LR-LINK LRES2217PT is a Mini PCI Express network card that adds two Gigabit Ethernet ports to industrial computers and single-board systems. It uses the Intel I350 chip and fits full-height Mini PCIe slots where space is limited.

Wider RJ45 Spacing and Thickened Gold Connectors

The card spaces its two RJ45 ports farther apart to accept industrial cables without interference. Thickened gold-plated connectors resist corrosion and maintain a solid link in vibration-prone environments. An integrated heatsink dissipates heat so the adapter runs stably inside poorly ventilated chassis.

Two Ports at 10/100/1000 Mbps on Mini PCIe

Each port negotiates 10, 100 or 1000 Mbps over standard twisted-pair cabling. The Mini PCIe host interface caps total throughput to the bandwidth of a single PCIe lane, so sustained line-rate traffic on both ports simultaneously will saturate the bus. The design saves motherboard expansion resources by delivering dual ports through one slot.

Questions about this item

Will the Intel I350-based card need any firmware updates or component swaps during its service life?

The card uses an Intel I350 controller with standard drivers across Windows, Linux and VMware; no user-serviceable parts or scheduled firmware maintenance are required.

What throughput ceiling appears first when both RJ45 ports run at full 1000Mbps continuously?

Each port is limited to 1000Mbps by the Gigabit Ethernet standard, so sustained wire-speed traffic on both ports simultaneously hits that 1000Mbps per-port ceiling.

How much heat does the LRES2217PT generate when operating all day inside a sealed industrial chassis?

The board includes an integrated heatsink rated for 0 °C to 55 °C ambient, designed to dissipate heat without active cooling in compact enclosures.
