Four-port PCIe 2.1 x4 server adapter

This quad-port copper network card fits a PCI Express 2.1 x4 slot and presents four RJ-45 connectors. It is built for servers that need extra 10/100/1000Base-T links without occupying multiple expansion slots. The plug-in form factor measures 5.9" by 2.2" and weighs approximately 3.84 oz.

Sustained multi-port throughput

Each port negotiates at 10, 100 or 1000 Mbps over twisted-pair cabling. Under continuous load the x4 host interface shares its bandwidth across all four channels, so aggregate throughput depends on how traffic is distributed among the ports. The card targets steady server workloads rather than short burst transfers.

PCIe 2.1 x4 lane budget

The adapter uses a single PCI Express 2.1 x4 connection, which caps total host bandwidth to the capacity of four lanes at that generation speed. Systems limited to PCIe 2.0 or fewer lanes will restrict the combined data rate accordingly. Buyers needing more than four gigabit ports or higher per-port speeds should consider alternative connectivity options.

Questions about this item

How much power does the PCIe 2.1 x4 quad-port card draw under sustained load?

The adapter uses a PCI Express 2.1 x4 host interface and four 10/100/1000Base-T RJ-45 ports on a low-profile plug-in card.

Which cables and switch ports are needed to use all four RJ-45 connections?

Each port accepts standard twisted-pair copper cable up to 1000 Mbps; connect them to matching 10/100/1000 switch ports.

Will the 5.9-inch by 2.2-inch card fit in a legacy server that only has PCIe 2.0 slots?

The PCI Express 2.1 x4 interface is backward compatible with PCIe 2.0 slots, and the low-profile dimensions suit most server chassis.
