Long-tail keywords: 10GBase-T stackable Layer 3 switch with 40G uplinks, Allied Telesis x550 campus aggregation switch.

Product Description

The AT-X550-18XTQ-10 is part of the Allied Telesis x550 Series, a purpose-built platform for 10 Gigabit aggregation at the campus distribution layer and wiring closet. Its 16 x 1G/10GBase-T ports provide dual-speed flexibility for connecting servers, NAS appliances, or high-performance workstations over existing Cat6A structured cabling, eliminating the cost of fiber optic infrastructure at the access tier. The 2 x 40G QSFP ports serve as high-bandwidth uplinks to core switches or as VCStack inter-switch links, giving each stack up to 80Gbps of stacking bandwidth. AlliedWare Plus, Allied Telesis's enterprise-class operating system, runs on all x550 models and delivers a comprehensive Layer 3 feature set including OSPF, BGP, Policy-Based Routing, and IPv6. VCStack technology allows multiple x550 switches to operate as a single logical device, simplifying management and providing a no single-point-of-failure architecture across the distribution layer. EPSRing and IEEE G.8032 Ethernet Ring Protection enable rapid failover for ring topologies, making the x550-18XTQ suitable for resilient building distribution designs. The switch is SDN-ready with OpenFlow v1.3 and supports sFlow for real-time performance monitoring and traffic analysis. With a power consumption of 128 W and a compact 1U rack form factor, the AT-X550-18XTQ-10 fits standard data closets and supports front-end management access.
