Allied Telesis AT-XEM2-12XTM-B01 12 X 1/2.5/5/10GBASE-T PORTS LINE CARD FOR SBX908GEN2 X950 SERIE

Product Overview

The Allied Telesis XEM2-12XTM-B01 is a 12-port 10GBase-T expansion module designed exclusively for installation into the SwitchBlade x950 or SBX908GEN2 modular chassis — it is not a standalone switch. Each of the 12 RJ-45 ports supports auto-negotiation across 1G, 2.5G, 5G, and 10G speeds, enabling cost-effective copper 10G upgrades without replacing existing Cat6A cabling infrastructure. The B01 suffix denotes a 1-year Allied Telesis Network Coverage Program (NCP) support bundle, providing hardware replacement and software update entitlements. For engineers expanding multi-gigabit wireless backhaul or high-density server access within an x950 chassis, this all-copper Allied Telesis XEM2 12-port 10GBase-T expansion module with 1-year NCP delivers the highest copper port density available in the XEM2 line.

Product Description

The AT-XEM2-12XTM-B01 is the all-copper variant in the XEM2 expansion module family, providing 12 x RJ-45 ports capable of 1/2.5/5/10GBASE-T operation — compared to the XEM2-8XSTM which offers 4 x SFP+ plus 4 x 10GBase-T ports. This distinction makes the XEM2-12XTM-B01 the preferred choice when maximum copper port density is required within the x950 or SBX908GEN2 chassis. Each port autosenses speed and duplex, supporting standard twisted pair cabling up to 100 meters at 10Gbps (Cat6A), making it a cost-efficient option versus fiber-based 10G expansion. The module's plug-in form factor slides directly into an available expansion slot on a compatible Allied Telesis modular chassis; no additional licensing is required for the ports themselves beyond the NCP bundle included with the B01 SKU. The XEM2-12XTM is particularly valuable for connecting IEEE 802.11ax (Wi-Fi 6/6E) access points, multi-gigabit workstations, or IP storage devices that demand 2.5G or 5G intermediate speeds. AlliedWare Plus firmware on the parent chassis provides granular per-port statistics, VLAN, QoS, and ACL configuration for all 12 expansion ports. The module weighs approximately 3.97 lb and measures 1.6" H x 4.3" W x 6.7" D. Hardware warranty and software update rights are covered for one year under the included NCP support contract; renewal terms are available from Creation Networks.

Key Features

• 12 x RJ-45 Multi-Gigabit Ports — Each port supports 1G/2.5G/5G/10G auto-negotiation, eliminating the need for fiber optics in high-speed access tier upgrades.
• 10GBase-T Copper over Cat6A — Delivers up to 10Gbps at distances up to 100 meters on standard twisted pair, reducing cabling costs versus SFP+ fiber alternatives.
• Exclusive Chassis Compatibility — Designed for the SwitchBlade x950 and SBX908GEN2 chassis only; not a standalone device. Verify available expansion slots before ordering.
• Highest Copper Density in XEM2 Family — 12 copper ports versus 4 copper + 4 SFP+ on the XEM2-8XSTM, maximizing access-tier density per slot.
• 1-Year NCP Bundle Included (B01) — Hardware advance replacement and AlliedWare Plus software updates included for 12 months from purchase.
• AlliedWare Plus Management — Full VLAN, QoS, ACL, and port statistics available through the parent chassis operating system.
• Plug-in Module Form Factor — Tool-free hot-insertion into available expansion slots on compatible Allied Telesis chassis.

Typical Applications

• Adding copper 10GBase-T access ports to an existing x950 or SBX908GEN2 campus core or distribution chassis
• Connecting IEEE 802.11ax (Wi-Fi 6/6E) access points requiring 2.5G or 5G uplinks over existing Cat5e/Cat6 cabling
• High-density multi-gigabit workstation access in financial trading floors, media production, or engineering design environments
• IP storage (NAS/SAN) connectivity requiring 5G or 10G copper access within a modular chassis infrastructure
• Data center top-of-rack copper server access where fiber optic patching is impractical

Technical Specifications

Frequently Asked Questions

Q: Is the AT-XEM2-12XTM-B01 a standalone switch?

No. It is an expansion module that must be installed into a compatible Allied Telesis modular chassis — either the SwitchBlade x950 or the SBX908GEN2. It cannot operate independently.

Q: What is the difference between the XEM2-12XTM and the XEM2-8XSTM?

The XEM2-12XTM-B01 provides 12 all-copper RJ-45 10GBase-T ports. The XEM2-8XSTM provides 4 x SFP+ fiber ports plus 4 x 10GBase-T copper ports. Choose the XEM2-12XTM when maximum copper density is the priority.

Q: What does the B01 suffix indicate?

The B01 suffix denotes a bundled 1-year Allied Telesis Network Coverage Program (NCP) support contract, which includes hardware advance replacement and AlliedWare Plus software update entitlements for 12 months.

Q: What cabling is required to achieve 10Gbps per port?

Cat6A or better is required for 10GBase-T at the full 100-meter distance. Cat6 cabling may support 10G at shorter distances (typically up to 55 meters). Cat5e is limited to 2.5G or 5G speeds.

Q: How many XEM2-12XTM modules can I install in an x950 chassis?

The SwitchBlade x950 supports multiple expansion slots; the exact number of available slots depends on the chassis configuration and existing line cards. Consult the x950 hardware installation guide or contact Creation Networks for slot availability assessment.

Q: Does this module support VLAN and QoS configuration?

Yes. All 12 ports are managed through AlliedWare Plus on the parent chassis, providing full Layer 2/3 feature support including VLANs, QoS, ACLs, and per-port statistics.
