Industrial dual-port Gigabit adapter

The LR-LINK LRES2203PF-2SFP is a Mini PCIe network card that provides two SFP ports running at 1000 Mbps. It is built around the Intel I350 controller and targets industrial PCs, single-board computers and embedded systems where space is limited.

Fits compact industrial builds.

This card suits engineers integrating networking into tight enclosures that expose a Mini PCIe slot. Builders with only full-size PCIe or M.2 sockets should look elsewhere, as the physical interface will not match.

Verify Mini PCIe slot and SFP transceiver needs

Confirm the host board has a free Mini PCIe connector and that the operating environment stays within 0 °C to 55 °C. You must also supply compatible SFP transceivers and fibre cabling, as neither is included with the adapter.

Questions about this item

Does my system need a Mini PCIe slot with a specific mechanical key to accept this adapter?

The card uses a Mini PCI Express interface; verify your board provides a Mini PCIe slot rather than an M.2 or full-size PCIe slot before purchase.

Will the 1000 Mbps SFP ports negotiate down to 100 Mbps if I connect legacy fibre transceivers?

The adapter complies with IEEE 802.1q and runs at 1000 Mbps; speed negotiation depends on the SFP modules installed, so match modules to the desired link rate.

Which LED colours confirm each port has established a 1000 Mbps link and is passing traffic?

A yellow LINK LED shows a 1000 Mbps connection and a green ACTIVE LED blinks when data is moving on that port.
