Allied Telesis AT-XEM2-12XS-B05 – 12-Port 10G SFP+ Line Card with 5-Year NCP

Product Overview

The Allied Telesis XEM2-12XS 10G SFP+ line card (AT-XEM2-12XS-B05) is a 12-port expansion module designed for the SBX908GEN2 chassis switch, delivering dual-rate 1G/10G SFP+ connectivity for high-density fiber aggregation. Bundled with a 5-year Network Coverage Program (NCP) support contract, this SKU provides a cost-effective path to long-distance 10 Gigabit Ethernet expansion for enterprise distribution and data center core deployments. As an Allied Telesis XEM2-12XS 10G SFP+ line card, it supports both 1000Base-X and 10GBase-X transceivers, making it compatible with a wide range of single-mode and multimode fiber optic infrastructure.

Product Description

The AT-XEM2-12XS-B05 installs into the SBX908GEN2 modular chassis switch, extending its port capacity with 12 hot-swappable SFP/SFP+ slots that operate at either 1 Gbps or 10 Gbps per port. This line card is purpose-built for optical network environments where fiber reach and density matter — each port accepts standard SFP (mini-GBIC) or SFP+ transceivers, enabling flexibility across different fiber types and distances. The module supports 10GBase-X and 1000Base-X network technologies, making it compatible with DAC cables, SR, LR, and ER optics depending on the transceiver chosen. Deploying multiple XEM2-12XS cards in a single SBX908GEN2 chassis allows network architects to build high-density 10G aggregation layers without additional top-of-rack switching hardware. This bundle includes a 5-year NCP support entitlement from Allied Telesis, covering software updates, firmware upgrades, and access to technical support for the full contract term. The NCP contract simplifies lifecycle planning and ensures the line card remains supported through firmware changes in the SBX908GEN2 operating environment. For campus cores, data center aggregation, or service provider access layers, the XEM2-12XS provides a scalable 10G fiber expansion path within the Allied Telesis chassis ecosystem. Available at Creation Networks (https://creationnetworks.net), this bundle is stocked for rapid deployment.

Key Features

• 12 x SFP/SFP+ Ports — Each port operates at 1G or 10G, accepting standard SFP (mini-GBIC) and SFP+ transceivers for flexible fiber connectivity.
• Dual-Rate Operation — 1000Base-X and 10GBase-X support on every port allows mixed-speed deployments within a single line card.
• SBX908GEN2 Compatible — Designed as a line card for the Allied Telesis SBX908GEN2 modular chassis, integrating with the chassis backplane and management plane.
• 5-Year NCP Support Bundle — Includes an Allied Telesis Network Coverage Program contract covering software maintenance, firmware access, and TAC support for five years.
• Optical Fiber Media — Supports single-mode and multimode fiber via appropriate SFP/SFP+ transceivers, enabling long-distance inter-site links.
• High-Density Aggregation — 12 ports per slot maximizes chassis utilization for 10G fiber aggregation without external switching hardware.
• Hot-Swap Capable — Line card insertion and removal supported in the SBX908GEN2 chassis without full system downtime.

Typical Applications

• 10G fiber aggregation layer in enterprise campus core deployments using SBX908GEN2
• Data center inter-rack and inter-pod 10G connectivity via fiber
• Service provider access or aggregation networks requiring dense 10G SFP+ port density
• High-density server connectivity for virtualization clusters over 10G fiber
• Long-distance site interconnects using single-mode SFP+ LR or ER transceivers

Technical Specifications

Frequently Asked Questions

Q: Which chassis is the AT-XEM2-12XS-B05 compatible with?

The XEM2-12XS line card is designed for the Allied Telesis SBX908GEN2 modular chassis switch. It is not interchangeable with fixed-form-factor switches. Verify chassis slot availability before ordering.

Q: What does the NCP 5-year bundle include?

The Network Coverage Program (NCP) contract provides access to Allied Telesis software and firmware updates, online technical documentation, and TAC (Technical Assistance Center) support for five years from the date of registration.

Q: Can I use both 1G and 10G transceivers in the same line card?

Yes. Each of the 12 ports independently accepts either SFP (1000Base-X) or SFP+ (10GBase-X) transceivers. Mixed-speed configurations are supported within a single XEM2-12XS card.

Q: What SFP+ transceiver types are supported?

The module accepts Allied Telesis-qualified SFP and SFP+ transceivers covering SR (short reach), LR (long reach), ER (extended reach), and DAC (direct attach copper) options. Third-party transceivers may require compatibility verification.

Q: Is the line card hot-swappable in the SBX908GEN2?

The SBX908GEN2 chassis supports hot-swap insertion of line cards. However, consult the chassis documentation for any traffic impact considerations during card insertion or removal under live load.

Q: How many XEM2-12XS cards can be installed in one SBX908GEN2 chassis?

The SBX908GEN2 supports multiple line card slots. The exact number of XEM2-12XS cards that can be populated depends on chassis slot capacity and power budget. Refer to the SBX908GEN2 hardware guide for slot configuration details.

Q: Where can I purchase the AT-XEM2-12XS-B05 with support?

The AT-XEM2-12XS-B05 is available from Creation Networks at https://creationnetworks.net, an authorized Allied Telesis reseller. Contact us for volume pricing or configuration assistance.
