  • Windows diagnostics utility enables detailed adapter testing

Gigabit fibre adapter for PCIe x1 slots

The Allied Telesis AT-2911SXA/SC-901 is a 1000Base-SX network card that fits a single PCI Express x1 lane. It provides one fibre port for gigabit connectivity in servers or workstations. The low-profile bracket is included alongside a standard-height bracket for flexible chassis fit. TAA compliance makes it suitable for government procurement.

Low-power operation with diagnostic tools

The PCIe x1 interface keeps power draw modest while delivering full gigabit bandwidth. A Windows utility runs detailed tests, diagnostics and analysis on the adapter. Priority queuing lets administrators shape traffic to match workload requirements. The card runs without active cooling in normal use.

Steady throughput under sustained load

The 2911 series maintains consistent gigabit performance during prolonged transfers rather than short bursts. Comprehensive configuration software helps engineers monitor adapter health over time. Priority queuing continues to enforce traffic policies when the link is fully utilised. The fibre interface avoids the electromagnetic interference that can degrade copper links.

Questions about this item

How do I install the AT-2911SXA/SC-901 into a PCI Express x1 slot and which bracket height should I use?

Insert the card into any available PCI Express x1 slot; the package includes both low-profile and standard-height brackets so you can match your chassis before securing the screw.

What maintenance or replacement will the 1000Base-SX fibre port need over time?

The LC duplex connector and fibre patch cord are the only replaceable items — keep the connector clean with a lint-free wipe and swap the patch cord if insertion loss rises.

What limit appears first on the 2911 series card during sustained 1000 Mbps throughput?

The single PCI Express x1 lane caps continuous bandwidth at the bus level, so sustained wire-speed traffic will hit that ceiling before the controller does.
