Allied Telesis AT-X510-52GTX-90 – 48-Port Stackable Gigabit Switch

Product Overview

The Allied Telesis AT-X510-52GTX-90 is a 48-port stackable Layer 3 gigabit switch designed for enterprise campus distribution, wiring closet aggregation, and high-density access deployments. As a core Allied Telesis x510 48-port stackable gigabit switch, it delivers wire-rate Layer 3 forwarding across all ports, making it well-suited for organizations that require scalable, policy-driven network segmentation. Four 10G SFP+ uplink ports provide high-bandwidth connectivity to core infrastructure, while VCStack stacking technology allows multiple units to be managed as a single logical switch—ideal for medium and large enterprise environments seeking operational simplicity and network redundancy.

Product Description

The AT-X510-52GTX-90 provides 48 ports of 10/100/1000T copper connectivity alongside 4 x 10G SFP+ uplink ports, delivering a total switching capacity that supports demanding enterprise traffic profiles. Running AlliedWare Plus—Allied Telesis's feature-rich network operating system—the switch supports advanced Layer 3 routing protocols including OSPF, BGP, and RIP, enabling it to serve as a distribution-layer device in multi-tier campus architectures. VCStack technology allows up to 8 units to be stacked together over the SFP+ ports, presenting the stack as a single management entity with a unified control plane. This Allied Telesis stackable enterprise Layer 3 switch supports IEEE 802.1Q VLANs, MSTP, and LACP for network resilience and traffic engineering. Quality of Service (QoS) features including DiffServ and IEEE 802.1p provide granular traffic prioritization for voice, video, and data workloads. The switch supports IPv4 and IPv6 routing natively, making it future-ready for dual-stack network environments. Integrated hardware-based ACLs allow administrators to enforce security policies at line rate. The device is built for TAA compliance with a -90 suffix indicating TAA country-of-origin requirements satisfied for US government and regulated procurement. Management options include SNMPv3, CLI, web GUI, and integration with Allied Telesis Vista Manager for centralized network management. Power over Ethernet is not included on this model, making it appropriate for data-only wiring closet or distribution applications where a separate PoE access layer is already deployed.

Key Features

• 48 x 10/100/1000T Copper Ports — Full-density gigabit access for end devices, servers, or downstream switches in a 1RU form factor.
• 4 x 10G SFP+ Uplinks — High-bandwidth fiber or DAC uplinks to core switches or spine layers, supporting standards-based 10GbE optics.
• VCStack Stacking — Stack up to 8 units over SFP+ ports for unified management, simplified provisioning, and chassis-like resilience without the chassis cost.
• AlliedWare Plus OS — Mature, feature-rich operating system with full CLI, SNMP, and REST API support for automation and scripting.
• Layer 3 Routing — Hardware-accelerated OSPF, BGP, RIPv1/v2, and static routing enables distribution-layer IP routing without an external router.
• Advanced QoS — 8 egress queues per port with DiffServ and 802.1p marking support for differentiated service across voice, video, and data traffic.
• Hardware ACLs — Line-rate access control lists enforce security and traffic policies without performance impact.
• IPv4 and IPv6 Dual-Stack — Native support for both protocol versions, enabling phased or full IPv6 migration.
• TAA Compliant — Satisfies Trade Agreements Act requirements for US Federal, state, and regulated procurement programs.
• Vista Manager Integration — Centralized management, topology visualization, and policy automation through Allied Telesis's network management platform.

Typical Applications

• Enterprise campus distribution layer aggregating access switches
• Wiring closet aggregation in multi-floor commercial buildings
• High-density server access in small to mid-size data center environments
• US Federal and government networks requiring TAA-compliant hardware
• Stacked deployments replacing modular chassis for simplified management

Frequently Asked Questions

Q: How many units can be stacked using VCStack?

Up to 8 AT-X510 units can be stacked together using the SFP+ uplink ports, presenting the entire stack as a single logical switch with one management IP and unified configuration.

Q: Does the AT-X510-52GTX-90 support Power over Ethernet?

No, this model does not support PoE. If PoE is required at the access layer, consider pairing it with a dedicated PoE access switch such as the Allied Telesis FS980M series.

Q: What routing protocols are supported?

The switch supports OSPF, BGP, RIPv1/v2, and static routing via hardware-accelerated Layer 3 forwarding under AlliedWare Plus.

Q: Is this switch TAA compliant for federal procurement?

Yes, the -90 suffix indicates TAA compliance, meeting Trade Agreements Act country-of-origin requirements for US Federal and government purchasing programs.

Q: What SFP+ optics are compatible with the uplink ports?

The 4 x SFP+ ports support Allied Telesis branded SFP+ transceivers for 10GBase-SR, 10GBase-LR, and other standard 10G form factors, as well as direct-attach copper (DAC) cables.

Q: Can the X510 be managed with Vista Manager?

Yes, the AT-X510 series integrates with Allied Telesis Vista Manager EX and NX for centralized topology management, automated provisioning, and network-wide policy control.

Q: What is the difference between the -90 and -80 variants?

The -90 suffix designates TAA-compliant country of origin. The -80 variant is the standard non-TAA version of the same hardware.
