Allied Telesis x900 Gigabit Ethernet Switches: AT-x900-12XT/S, AT-x900-24XT, AT-x900-24XS

The Allied Telesis x900 Series represents a family of advanced Layer 3 switches designed to deliver unmatched performance, flexibility, and reliability. Engineered for the core and aggregation layers of enterprise networks and FTTx infrastructures, these switches feature wire-speed IPv4 and IPv6 routing.

The x900 series stands out with its high-availability hardware design, including dual hot-swappable power supplies (AC or DC). With a switching fabric of up to 150 Gbps and a forwarding rate of 71.4 Mpps, it handles data-intensive applications with ease. The inclusion of EPSR (Ethernet Protected Switched Rings) ensures carrier-grade resiliency with sub-50ms recovery times. Dual 30Gbps expansion bays provide future-proof scalability for 10GbE uplinks or high-bandwidth stacking. Running on the industry-leading AlliedWare Plus OS, the x900 series offers a sophisticated set of features for QoS, security, and advanced routing protocols like OSPF and BGP-4.

Key Specifications:

• Performance: Non-blocking wire-speed L3 switching and routing.

• Resiliency: EPSR for rapid ring recovery and VRRP for gateway redundancy.

• Expandability: Two 30Gbps expansion slots for 10GbE modules or stacking.

• Traffic Management: Advanced QoS, DiffServ, and rate limiting at the port level.

• Data Integrity: Hardware-based IPv6 support and Jumbo frame (10KB) support.
