Allied Telesis AT-XEM2-12XS V2-B05 – 12-Port 1G/10G SFP+ Line Card with 5-Year NCP

Product Overview

The Allied Telesis XEM2 SFP+ expansion module (AT-XEM2-12XS V2-B05) is the second-generation 12-port 1G/10G line card for the SBX908GEN2 chassis switch, bundled with a 5-year Network Coverage Program support contract. Designed for high-density optical fiber aggregation and 10 Gigabit Ethernet connectivity, this Allied Telesis XEM2 SFP+ expansion module accepts both SFP (1000Base-X) and SFP+ (10GBase-X) transceivers per port, enabling mixed-speed deployments on a single card. The V2 revision delivers the same port configuration as the original XEM2-12XS with the added benefit of second-generation hardware and the included NCP bundle, making it the current recommended line card option for new SBX908GEN2 installations requiring long-term vendor support coverage.

Product Description

The AT-XEM2-12XS V2-B05 installs into available line card slots in the Allied Telesis SBX908GEN2 modular chassis, adding 12 hot-swappable SFP/SFP+ ports that operate at either 1 Gbps (1000Base-X) or 10 Gbps (10GBase-X) per port. The V2 designation identifies the current hardware revision, which is the shipping version for new deployments and replaces the original XEM2-12XS. Each port independently accepts standard SFP (mini-GBIC) or SFP+ transceivers, providing flexibility to mix short-reach, long-reach, and extended-reach fiber optics as well as DAC direct-attach copper cables across the 12 slots. For data center and campus environments that have already deployed the SBX908GEN2 chassis, adding XEM2-12XS V2 line cards is the most direct path to expanding 10G fiber port density without additional chassis hardware. Multiple line cards can be installed in a single SBX908GEN2 to build high-density aggregation layers for server farms, storage networks, or inter-switch fiber links. The included 5-year NCP support contract from Allied Telesis provides firmware updates, software maintenance releases, and access to Allied Telesis TAC for the duration of the contract — an important consideration for organizations with strict software lifecycle and support policies. This bundle simplifies procurement by combining hardware and support into a single SKU, avoiding separate support contract purchasing. The AT-XEM2-12XS V2-B05 is available from Creation Networks (https://creationnetworks.net), an authorized Allied Telesis reseller providing commercial networking equipment to enterprise and service provider customers.

Frequently Asked Questions

Q: What is the difference between the AT-XEM2-12XS-B05 and the AT-XEM2-12XS V2-B05?

The V2-B05 is the second-generation hardware revision of the XEM2-12XS line card. Both provide 12 x 1G/10G SFP/SFP+ ports for the SBX908GEN2 chassis and include a 5-year NCP support bundle. The V2 is the current shipping revision recommended for new deployments. Confirm chassis firmware compatibility with Allied Telesis documentation before mixing V1 and V2 cards.

Q: Which chassis does the AT-XEM2-12XS V2-B05 install into?

This line card is designed for the Allied Telesis SBX908GEN2 modular chassis switch. It is not compatible with fixed-form-factor switches or other Allied Telesis chassis models. Verify available line card slots and chassis power budget before ordering.

Q: Can 1G and 10G transceivers be mixed on the same line card?

Yes. Each of the 12 ports independently supports either SFP (1000Base-X at 1 Gbps) or SFP+ (10GBase-X at 10 Gbps) transceivers. Mixed-speed port configurations are fully supported within a single XEM2-12XS V2 card.

Q: What does the 5-year NCP support contract cover?

The Allied Telesis Network Coverage Program (NCP) provides firmware and software updates, access to new feature releases, and Allied Telesis TAC (Technical Assistance Center) support for five years from contract registration. It ensures continued software lifecycle coverage for the line card within the SBX908GEN2 operating environment.

Q: What SFP+ transceiver options are available for this line card?

The XEM2-12XS V2 supports Allied Telesis-qualified SFP and SFP+ transceivers including SR (850nm multimode), LR (1310nm single-mode), ER (1550nm single-mode), and DAC direct-attach copper cables. Third-party transceivers may require compatibility validation with the SBX908GEN2 chassis software.

Q: How many XEM2-12XS V2 cards can be installed in one SBX908GEN2?

The number of line card slots available in the SBX908GEN2 chassis determines the maximum number of XEM2-12XS V2 cards that can be populated. Refer to the SBX908GEN2 hardware installation guide for slot count, card ordering, and power budget constraints.

Q: Where can I purchase the AT-XEM2-12XS V2-B05?
