Allied Telesis AT-2911T/2-901 10/100/1000T X 2 PCIE X1 DESKTOP COPPER ADAPTER

Product Overview

The Allied Telesis AT-2911T/2-901 is a dual-port PCIe x1 Gigabit Ethernet NIC with two 10/100/1000Base-T RJ-45 copper ports, designed to add or replace two independent Gigabit Ethernet interfaces in a desktop, workstation, or rackmount server via a single PCIe x1 slot. Based on the Broadcom BCM5718 chipset with PCIe x1 v2 interface, this card delivers up to 250 MB/s host bus throughput and full 1GbE wire-speed performance on both ports simultaneously. The /2 designation confirms the dual-port configuration, distinguishing it from the single-port AT-2911T. TAA compliance under the -901 suffix makes this adapter eligible for US federal and government procurement. Available from Creation Networks at creationnetworks.net.

Product Description

The AT-2911T/2-901 is a plug-in PCI Express x1 card from the Allied Telesis AT-2911 Series, providing two independent 10/100/1000Base-T RJ-45 ports over twisted-pair cable up to 100 meters. Built on the Broadcom BCM5718 dual-port Gigabit Ethernet controller, it delivers low-latency, high-throughput connectivity for servers requiring multiple network interfaces — such as network segmentation, fault-tolerant bonding, or connecting to separate VLANs — without consuming a high-bandwidth PCIe x4 or x8 slot. The PCIe x1 v2 interface provides up to 250 MB/s of host bus bandwidth per card, well above the 125 MB/s aggregate throughput of dual 1GbE links, ensuring the host bus is never a bottleneck. The AT-2911T/2 is suited for both desktop replacement scenarios (where on-board NIC has failed or is insufficient) and server multi-homing deployments. Supports cost-effective Cat5e/Cat6 twisted-pair cabling for full 1000Mbps operation to 100m. TAA compliance under the Trade Agreements Act qualifies this NIC for US federal, state, and government purchasing programs. Country of origin is Singapore. The card is RoHS compliant and ships in standard retail (-901) packaging.

Frequently Asked Questions

Q: What is the difference between the AT-2911T and the AT-2911T/2?

The AT-2911T is a single-port Gigabit Ethernet NIC with one RJ-45 port. The AT-2911T/2 (note the /2 suffix) adds a second independent RJ-45 port on the same PCIe x1 card, giving the host computer two separate GbE interfaces without consuming an additional slot.

Q: Will this card fit in a PCIe x4 or x16 slot?

Yes. A PCIe x1 card is physically and electrically compatible with any larger PCIe slot (x4, x8, x16). The card will operate at x1 bandwidth regardless of the slot size used.

Q: Can the two ports be bonded/teamed for higher throughput or redundancy?

Yes. The two ports can be configured for IEEE 802.3ad link aggregation (LACP) or active-backup teaming in the OS or server management software, providing either up to 2Gbps of aggregate throughput or automatic failover between the two links.

Q: Is the AT-2911T/2-901 TAA compliant?

Yes. The -901 suffix indicates this is the TAA-compliant variant, making it eligible for US federal, state, and government purchasing contracts under the Trade Agreements Act.

Q: What cabling is required?

Standard Cat5e or Cat6 twisted-pair Ethernet cable is required for 1000Base-T (Gigabit) operation at up to 100 meters. Cat5e is sufficient for most deployments; Cat6 is recommended for new installations or high-interference environments.
