Allied Telesis AT-X930-52GTX-901 – 48-Port Gigabit Stackable Layer 3 Switch

Product Overview

The Allied Telesis x930 48-port Gigabit stackable switch (AT-X930-52GTX-901) provides 48 x 10/100/1000Base-T access ports and four 10G SFP+ uplinks in a 1RU form factor, delivering wire-speed Layer 3 forwarding for high-density enterprise access and distribution deployments. As a member of the x930 Series, it supports VCStack virtual chassis stacking of up to eight units, enabling large-scale wired networks to be managed as a single logical device. The AT-X930-52GTX-901 includes a redundant PSU bay, IPv6 support, and the full Allied Telesis Management Framework (AMF) feature set, making it well-suited for campus access layers, enterprise distribution tiers, and data center top-of-rack environments where port density, resilience, and unified management are required.

Product Description

The AT-X930-52GTX-901 is a fixed-configuration Layer 3 switch with 48 Gigabit copper access ports and four dedicated 10GBase-X SFP+ uplinks, designed for environments where maximum copper port density is the primary requirement. The 10G SFP+ uplinks provide high-bandwidth connections to distribution or core switches, and support both direct attach copper (DAC) cables and optical transceivers for flexible cabling topologies. VCStack stacking allows up to eight x930-52GTX units to operate as a single logical chassis, dramatically simplifying management overhead in large access layer deployments. Stacking bandwidth reaches up to 160 Gbps per unit, ensuring that stacked configurations do not create bandwidth bottlenecks at inter-switch links. VCStack Long Distance (LD) extends the stacking domain over fiber, permitting physically separated switches in different buildings or floors to participate in the same stack. Layer 3 routing capabilities include static routes, RIPv1/v2, OSPFv2/v3, and BGP, enabling the switch to serve as a distribution-layer router for inter-VLAN and inter-site routing without an external routing appliance. The Allied Telesis Management Framework (AMF) enables zero-touch deployment, automated configuration backup, and single-pane management of all AMF nodes, reducing operational costs in large campus networks. EPSR (Ethernet Protection Switched Ring) provides sub-50ms ring failover for access ring topologies connected to this switch. Tri-authentication (802.1X, MAC-based, and web authentication) on access ports delivers granular endpoint access control across the 48-port edge. The x930-52GTX is available at Creation Networks (https://creationnetworks.net), an authorized Allied Telesis reseller serving enterprise networking markets.

Key Features

• 48 x 10/100/1000Base-T Ports — Full Gigabit copper access density for high-density workgroup or access layer deployments on standard Cat5e/6 cabling.
• 4 x SFP+ 10G Uplinks — Dedicated 10 Gigabit uplink ports for high-bandwidth connectivity to distribution or core switches via fiber or DAC.
• VCStack Stacking — Stack up to eight x930 units as a single logical device with up to 160 Gbps stacking bandwidth per switch for simplified management and high availability.
• VCStack LD (Long Distance) — Extends stacking over long-distance fiber links, supporting distributed campus designs across multiple buildings.
• Layer 3 Routing — Static routing, RIP, OSPF, and BGP support for inter-VLAN and inter-site routing at the distribution or access tier.
• Redundant PSU Bay — Optional second power supply for load-sharing and hot-swap replacement, eliminating power as a single point of failure.
• Allied Telesis AMF — Automates provisioning, zero-touch replacement, and network-wide firmware upgrades across the entire AMF domain.
• EPSR Ring Resilience — Sub-50ms ring failover for Ethernet ring topologies at the network access layer.
• Tri-Authentication — Concurrent 802.1X, MAC-based, and web authentication per port for comprehensive endpoint access control.
• IPv6 Ready — Full IPv6 routing and management support prepares the network for dual-stack and IPv6-only environments.
• SDN/OpenFlow Ready — Supports OpenFlow v1.3 for integration with SDN controllers and programmable network architectures.

Typical Applications

• High-density enterprise campus access layer serving end-user devices and IP phones
• Distribution layer switch in mid-to-large campus networks with VCStack for redundancy
• Data center top-of-rack switch with 10G uplinks to spine or aggregation layer
• Multi-building campus deployments using VCStack LD over inter-building fiber
• Access layer for dense virtualization environments requiring 10G server uplinks
• Deployments requiring tri-authentication for strict endpoint compliance at the edge

Frequently Asked Questions

Q: How does VCStack differ from traditional switch stacking?

VCStack creates a single logical switching entity from multiple physical switches. All units share one management IP, one configuration file, and one forwarding table. This eliminates the need for spanning tree between stacked switches and allows link aggregation across physical units for loop-free, high-bandwidth inter-switch links.

Q: Can the AT-X930-52GTX-901 stack with other x930 models, such as the 28-port x930-28GSTX?

Yes. Mixed-model VCStack configurations are supported within the x930 Series. A stack can combine x930-52GTX and x930-28GSTX units, subject to running compatible AlliedWare Plus firmware versions across all members.

Q: Does this switch support PoE for powering access points or IP phones?

The AT-X930-52GTX-901 does not include PoE on access ports. For PoE requirements, refer to Allied Telesis x930 PoE models or the x550 Series. Confirm PoE requirements before specifying this switch for VoIP or wireless AP deployments.

Q: What is the stacking bandwidth between units?

Each x930 switch supports up to 160 Gbps of VCStack stacking bandwidth per unit. This provides sufficient throughput to prevent stacking links from becoming a bottleneck in most deployment scenarios.

Q: How is redundant power configured?

The AT-X930-52GTX-901 has a second PSU bay. An optional power supply module can be ordered separately and installed without powering down the switch. Both PSUs operate in load-sharing mode, providing both redundancy and combined capacity.

Q: Is the x930-52GTX compatible with Allied Telesis AMF Cloud?

The x930 Series integrates with AMF Cloud, enabling centralized management, monitoring, and automation for remote sites and distributed campus networks through a cloud-hosted management platform.
