Product Overview
The Allied Telesis AT-XEM2-12XTM is a 12-port multi-rate expansion module (line card) for the Allied Telesis SBx908 Gen2 and x950 series chassis switches. Each port supports 1G/2.5G/5G/10GBASE-T copper connectivity, enabling flexible high-density 10GbE access or aggregation without requiring SFP+ transceivers. This listing (AT-XEM2-12XTM-B01, $220) represents an alternate pricing configuration — buyers should verify compatibility and procurement details with Creation Networks before ordering.
Product Description

The AT-XEM2-12XTM expansion module installs into Allied Telesis SBx908 Gen2 and x950 chassis switches to provide 12 additional copper ports supporting speeds of 1G, 2.5G, 5G, and 10GBASE-T. This multi-rate capability makes it highly adaptable for connecting a mix of legacy Gigabit and newer multi-gig workstations, Wi-Fi 6/6E access points, and servers — all over standard Cat6A cabling up to 100 meters at 10Gbps. The XEM2 form factor is the second-generation expansion module platform for Allied Telesis modular chassis, offering improved density and power efficiency compared to the original XEM platform. Deploying 12xTM modules across a populated chassis allows network operators to build high-port-count 10GbE switching fabrics without the cost of optical transceivers. This B01 configuration listing is priced at $220; buyers should contact Creation Networks to confirm whether this SKU represents a specific bundled offering, a refurbished unit, or a regional variant compared to the standard AT-XEM2-12XTM listing.
