Four-port Gigabit server upgrade

The StarTech ST4000SPEXI adds four RJ-45 Gigabit Ethernet ports to a client, server or workstation through a single PCI Express x4 slot. It uses an Intel I350-AM4 chipset and supports 10, 100 and 1000 Mbps speeds with IEEE 802.3x flow control and 802.1Q VLAN tagging. A low-profile bracket is included for compact chassis.

Sustained multi-port throughput

Each port negotiates independently at 10, 100 or 1000 Mbps full duplex, so simultaneous traffic on all four links can approach the 2000 MB/s PCIe x4 bandwidth ceiling. The Intel controller offloads checksum and segmentation tasks, keeping CPU utilisation low during continuous file transfers or virtual-machine bridging. LEDs show link status and 100/1000 Mbps speed per port.

PCIe x4 slot requirement

The card requires an open PCI Express x4 slot (or larger) to deliver its rated 2000 MB/s host bandwidth. Systems limited to x1 or x2 electrical connections will restrict total aggregate throughput across the four ports. Verify slot availability and form-factor clearance before purchase.

Questions about this item

How much power does the Intel I350-AM4 chipset draw when all four ports run at 1000 Mbps all day?

The card uses a single PCI Express x4 slot and the Intel I350-AM4 chipset is designed for efficient operation in servers and workstations running continuously.

Does my system need a PCI Express x4 slot and four RJ45 cables to use all four ports?

Yes, the adapter requires one PCI Express x4 slot and each of the four ports uses a standard RJ45 connector for twisted-pair cable.

Will the card negotiate 10 Mbps or 100 Mbps links on older switches that only support IEEE 802.3 and 802.3u?

The adapter supports IEEE 802.3 10BASE-T, IEEE 802.3u 100BASE-TX and IEEE 802.3ab 1000BASE-T so it will automatically negotiate the highest speed the link partner offers.
