Allied Telesis AT-X9EM/XT4-B01 – 4-Port 10GBase-T Expansion Module with 1-Year NCP

Product Overview

The Allied Telesis X9EM/XT4-B01 is an Allied Telesis X9EM/XT4 4-port 10GBase-T expansion module with a 1-year NCP (Network Coverage Program) support bundle, designed to add copper 10G connectivity to compatible x900 and x950 series switches. This is not a standalone device; it requires a compatible Allied Telesis x930 or x950 series chassis with an available expansion slot. The B01 bundle suffix indicates 1-year NCP support is included, providing software updates, hardware replacement, and technical support for the first year. Unlike SFP+-based 10G expansion, the XT4 uses standard RJ-45 Cat6A cabling for 10GBase-T, reducing infrastructure costs in environments already cabled with copper.

Product Description

The AT-X9EM/XT4 expansion module provides 4x 10GBase-T (IEEE 802.3an) ports via RJ-45 connectors, supporting full-duplex 10 Gigabit Ethernet over Cat6A or Cat7 copper cabling at distances up to 100 meters. When installed in a compatible Allied Telesis x930 series switch, the module extends the chassis with dedicated 10GBase-T interfaces that can serve as high-speed server connections, inter-switch links, or NAS/SAN access ports. The 10GBase-T interface type is particularly valuable in data centers or enterprise wiring closets already structured with Cat6A copper, avoiding the optical fiber infrastructure investment required for SFP+-based 10G expansion. The B01 bundle includes the Allied Telesis 1-year NCP service, covering advance hardware replacement, software maintenance releases, and access to Allied Telesis technical support — delivering a complete purchase that covers both hardware and first-year support in a single SKU. The AT-X9EM/XT4-B01 is the copper-10G counterpart to SFP+-based expansion modules, enabling network architects to deploy 10G where copper structured cabling is already in place.

Key Features

• 4x 10GBase-T (RJ-45) Ports — IEEE 802.3an 10G copper, up to 100m on Cat6A/Cat7 cabling.
• x930/x950 Series Compatible — Slots into the expansion bay of compatible Allied Telesis x930 and x950 series switches.
• 1-Year NCP Bundle Included — Advance hardware replacement, software maintenance, and technical support for year one.
• Copper 10G — No Fiber Required — Leverages existing Cat6A structured cabling infrastructure, reducing deployment cost.
• Full-Duplex 10 Gigabit Ethernet — 20 Gbps aggregate throughput across all 4 ports for high-bandwidth server and storage links.
• Standard RJ-45 Interface — Eliminates transceiver costs and simplifies cabling compared to SFP+ alternatives.

Typical Applications

• Enterprise data center — 10G copper uplinks from x930/x950 switches to servers, NAS, or SAN using existing Cat6A infrastructure
• Campus core distribution — 10GBase-T inter-switch links between wiring closet switches over structured copper cabling
• High-performance workstation connectivity — dedicated 10G copper ports for video editing, CAD, or engineering workstations
• Storage networking — 10GBase-T connections to iSCSI or NAS storage arrays without fiber infrastructure investment

Frequently Asked Questions

Q: Does the AT-X9EM/XT4-B01 work as a standalone device?

No. The AT-X9EM/XT4-B01 is an expansion module that must be installed in a compatible Allied Telesis x930 or x950 series switch expansion slot. It does not operate independently.

Q: What cabling does 10GBase-T require?

10GBase-T operates over Cat6A (augmented Category 6) or Cat7 copper cabling at distances up to 100 meters. Cat6 cabling supports 10GBase-T at shorter distances (up to approximately 55 meters).

Q: What does the B01 suffix indicate?

The B01 suffix indicates the product is bundled with 1-year NCP (Network Coverage Program) support, which covers advance hardware replacement, software maintenance releases, and Allied Telesis technical support for one year from purchase.

Q: Why choose 10GBase-T over 10G SFP+ expansion?

10GBase-T uses standard RJ-45 copper cabling, eliminating the need for optical transceivers and fiber infrastructure. If your environment is already cabled with Cat6A copper, 10GBase-T provides lower total cost of ownership for 10G deployments.

Q: What x930 series switches are compatible with the X9EM/XT4?

The X9EM/XT4 is compatible with Allied Telesis x930 series switches that include an expansion module slot, including the x930-28GPX and x930-52GPX models. Verify the target switch datasheet for expansion slot availability.

Q: Where can I purchase the AT-X9EM/XT4-B01?

The AT-X9EM/XT4-B01 is available through Creation Networks at creationnetworks.net, an authorized Allied Telesis reseller.
