1000Base-SX PCIe adapter

The Allied Telesis AT-2911SX/ST-901 is a Gigabit fibre network card that plugs into a PCI Express x1 slot. It targets servers and workstations that need a 1000Base-SX uplink over multimode fibre. The low-profile bracket fits standard and low-profile chassis alike.

Low power draw and silent operation

The card draws minimal power from the PCIe bus, so it adds negligible heat to the system and requires no auxiliary power connector. Because it has no fan, it runs completely silent, making it suitable for quiet office or rack environments.

Windows diagnostics and priority queuing

A bundled Windows utility runs detailed tests, diagnostics and analysis on the adapter, helping administrators verify link health quickly. The driver also exposes priority queuing, letting you tag traffic so latency-sensitive applications get preferential treatment on congested links.

Questions about this item

How do I install the AT-2911SX/ST-901 into a PCI Express slot and what step is often missed?

Insert the card into a free PCIe x1 or wider slot, secure the bracket screw, then install the Windows utility to run diagnostics and configure priority queuing.

What maintenance or replacement will the AT-2911SX/ST-901 need over time?

The 1000Base-SX fibre connector may need cleaning if signal loss appears; no user-serviceable parts are on the card itself.

What limit appears first on the AT-2911SX/ST-901 during sustained gigabit traffic?

The 1000Base-SX fibre link caps sustained throughput at 1000 Mbps, which is reached before the PCIe x1 bus saturates.
