Allied Telesis AT-DNC10T-901 TAA RJ45 10G NIC LF TAA RJ45 10G NIC LF

Product Overview

The Allied Telesis AT-DNC10T-901 is a TAA-compliant 10 Gigabit PCIe NIC with an RJ45 copper port supporting Multi-Gig speeds from 100 Mbps through 10GBase-T over standard Cat6A cabling. This Allied Telesis 10G PCIe NIC RJ45 copper adapter is the copper-media variant of the DNC10 series — distinct from the DNC10SP (which uses an SFP+ slot for fiber optics) and the DNC10LC (which has a fixed LC fiber connector). The DNC10T-901 is the right choice when existing structured cabling infrastructure uses Cat6A and optical fiber runs are not available or not required, enabling 10GbE server connectivity without a fiber plant.

Product Description

The DNC10T-901 installs in a PCIe x4 slot and provides a single 10GBase-T RJ45 port with full Multi-Gig auto-negotiation, supporting link rates of 100 Mbps, 1G, 2.5G, 5G, and 10G on a single copper RJ45 connection. This multi-speed capability makes the DNC10T particularly valuable in environments migrating from 1G to 10G infrastructure, as it will auto-negotiate with existing 1G switches while delivering 10G throughput once the switching infrastructure is upgraded. The card is powered by the Aquantia (Marvell) AQC10x series chipset, an energy-efficient design that draws under 2W at normal operation — well below the thermal output of competing 10GBase-T adapters. The PCIe x4 interface delivers up to 2000 MB/s between the NIC and the host motherboard, preventing the bus from becoming a bottleneck. The DNC10T-901 carries TAA compliance for US federal and government procurement. At 10GBase-T, Cat6A cabling is required for distances up to 100 meters; Cat6 supports shorter runs at 10G. Wake-on-LAN is supported for remote management scenarios. Allied Telesis validates this card across a broad range of operating systems and server platforms to ensure production-ready compatibility.

Key Features

• Multi-Gig RJ45 Copper Port — Auto-negotiates at 100M / 1G / 2.5G / 5G / 10G over a single RJ45 connector, protecting existing structured cabling investments.
• 10GBase-T Standard — Full 10 Gbps throughput over Cat6A copper cabling up to 100 meters.
• TAA Compliant — -901 suffix confirms Trade Agreements Act compliance for US federal and government procurement.
• PCIe x4 Host Interface — Up to 2000 MB/s bus bandwidth; backward compatible with x8 and x16 slots.
• Aquantia (Marvell) AQC10x Chipset — Sub-2W power consumption at normal operation reduces server thermal load compared to competing 10GBase-T NICs.
• Wake-on-LAN (WoL) — Remote wake capability for servers and managed workstations over the network.
• Low-Profile Form Factor — Fits in standard-height and low-profile PCIe slots for compact server chassis.

Typical Applications

• Server-to-switch 10GbE connectivity over existing Cat6A copper infrastructure
• Phased 1G-to-10G migrations where multi-gig auto-negotiation preserves switch compatibility during transition
• Enterprise and campus server rooms without fiber plant access
• Federal and government deployments requiring TAA-compliant 10G copper NICs
• Workstation and desktop deployments requiring 10GbE NAS or storage connectivity over copper

Frequently Asked Questions

Q: What is the difference between the DNC10T, DNC10SP, and DNC10LC?

The DNC10T uses a copper RJ45 port with 10GBase-T and Multi-Gig auto-negotiation (100M through 10G) over Cat6A cabling. The DNC10SP uses an SFP+ slot where you install your own 1G SFP or 10G SFP+ optical transceiver for fiber connectivity. The DNC10LC has a fixed built-in LC fiber optic connector that cannot be changed, providing physical security for fiber installations. Choose DNC10T for copper Cat6A deployments, DNC10SP for flexible fiber with upgradeable optics, and DNC10LC for fixed-optic fiber security.

Q: What cabling is required for 10G operation?

10GBase-T at full 10 Gbps requires Cat6A cabling for distances up to 100 meters. Cat6 (not Cat6A) may support 10G at shorter distances (typically up to 55 meters) depending on the cable and installation quality.

Q: Does the DNC10T support speeds below 10G?

Yes. The DNC10T features Multi-Gig auto-negotiation and will link at 100 Mbps, 1G, 2.5G, 5G, or 10G depending on the connected switch or device. This makes it compatible with existing 1G switching infrastructure while being future-ready for 10G.

Q: Is the AT-DNC10T-901 TAA compliant?

Yes. The -901 suffix confirms TAA (Trade Agreements Act) compliance for US federal government, DoD, and GSA schedule procurement.

Q: What PCIe slot is required?

The card uses a PCIe x4 edge connector and is backward compatible with x8 and x16 slots. A minimum of a PCIe x4 slot is required for full performance.
