Allied Telesis AT-2911SXA/LC-901 network card

SKU CH-60VB-JW75H MPN AT-2911SXA/LC-901

A PCI Express x1 Gigabit Ethernet card with one 1000Base-SX fibre port, low-profile and standard-height brackets, and TAA compliance

  • PCI Express x1 interface delivers maximum bus bandwidth and low power consumption
  • Single 1000Base-SX fibre port provides Gigabit Ethernet connectivity over multi-mode fibre
  • Low-profile and standard-height brackets included for flexible chassis compatibility
  • TAA-compliant design meets US federal procurement requirements
  • Comprehensive Windows utility enables detailed diagnostics, testing and priority-queue configuration

PCI Express x1 Gigabit adapter

The Allied Telesis AT-2911SXA/LC-901 is a PCI Express x1 network card with a single 1000Base-SX fibre port. It targets administrators adding managed Gigabit connectivity to servers or workstations that have an open x1 slot. The low-profile bracket is included for compact chassis and a standard-height bracket is also supplied for full-size enclosures.

Upgrade from legacy PCI or 100 Mb fibre

This card replaces older PCI-based Gigabit or Fast Ethernet fibre adapters that cannot saturate a modern bus. The jump is worth it when the host system has a free PCIe x1 lane and the network backbone already runs 1000Base-SX multimode fibre. It also suits migrations where TAA compliance becomes a procurement requirement.

Sustained line-rate throughput

Under continuous load the adapter maintains full-duplex Gigabit speeds without throttling, thanks to the efficient PCIe x1 interface and low-power design. The on-board diagnostics utility allows administrators to monitor link health and queue behaviour during prolonged transfers. Priority queuing keeps latency predictable when multiple traffic classes share the same uplink.

Questions about this item

What slot type and bracket heights does the AT-2911SXA/LC-901 require?

The card plugs into a PCI Express x1 slot and ships with both low-profile and standard-height brackets for either chassis style.

What is the most common mistake when installing the AT-2911SXA/LC-901?

Forgetting to swap the bracket before slotting the card, so the port faces the wrong way for the case opening.

When will the LC fibre connector on the AT-2911SXA/LC-901 need attention?

The LC connector should be inspected and cleaned with a fibre scope and swabs whenever link errors appear or after any unplugging.
