Allied Telesis AT-X930-28GSTX-901 – 24-Port Layer 3 Switch with Dual PSU Bays

Product Overview

The Allied Telesis x930-28GSTX Layer 3 switch (AT-X930-28GSTX-901) delivers 24 ports of 10/100/1000T copper with four combo SFP slots and four dedicated SFP+ 10G uplink ports, purpose-built for enterprise distribution and network core deployments. As part of the Allied Telesis x930 Series, this stackable Gigabit switch supports VCStack virtual chassis stacking up to eight units, providing a high-density, resilient distribution layer for demanding wired and wireless networks. The AT-X930-28GSTX-901 includes dual hot-swappable PSU bays, meeting enterprise uptime requirements without scheduled maintenance windows. With native Allied Telesis AMF management integration and Layer 3 routing capability, it is a direct fit for campus distribution and data center access layers where redundancy and unified management are priorities.

Product Description

The AT-X930-28GSTX-901 is a 1RU rack-mountable Layer 3 switch offering 24 x 10/100/1000Base-T access ports alongside four combo 100/1000 SFP slots and four dedicated 10GBase-X SFP+ uplink ports, totaling 28 usable network ports. Dual hot-swappable, load-sharing power supply bays ensure that a single PSU failure does not interrupt switching operations — replacement can be performed without powering down the switch. The switch participates in Allied Telesis VCStack (Virtual Chassis Stacking), allowing up to eight x930 units to be combined into a single logical switch with up to 160 Gbps of aggregate stacking bandwidth per unit. VCStack Long Distance (LD) extends stacking over fiber, supporting geographically distributed campus designs where physical proximity is not guaranteed. Layer 3 routing capabilities include static routing and dynamic routing protocols, enabling the x930-28GSTX to function as a distribution or collapsed core switch without requiring a separate router. The Allied Telesis Management Framework (AMF) enables zero-touch provisioning, automated configuration backup, and centralized management across all AMF-enabled devices in the network — reducing operational overhead for large-scale deployments. The integrated Wireless Manager allows direct management of Allied Telesis TQ Series access points from the x930 console, consolidating wired and wireless administration on a single platform. Security capabilities include tri-authentication (802.1X, MAC-based, and web authentication), ACL-based traffic control, DHCP snooping, dynamic ARP inspection, and loop guard for cabling fault detection. EPSR (Ethernet Protection Switched Ring) support provides sub-50ms ring recovery for resilient access ring topologies. The x930-28GSTX is available from Creation Networks (https://creationnetworks.net) as an authorized Allied Telesis reseller.

Key Features

• 4 x Combo 100/1000 SFP Slots — Shared with copper ports, providing flexibility to use fiber uplinks where copper distances are a limitation.
• 4 x SFP+ 10G Uplink Ports — Dedicated 10 Gigabit uplinks for high-bandwidth connections to distribution or core switching layers.
• Dual Hot-Swap PSU Bays — Load-sharing, hot-swappable power supplies eliminate single points of failure in the power path without switch downtime.
• VCStack Virtual Chassis Stacking — Stack up to eight x930 units into a single logical switch with up to 160 Gbps stacking bandwidth, simplifying management and increasing port density.
• Layer 3 Routing — Full Layer 3 forwarding with static and dynamic routing protocols supports distribution and collapsed-core architectures.
• Allied Telesis AMF Integration — Automates provisioning, configuration backup, and network-wide upgrades across all AMF nodes from a single management point.
• Wireless Manager — Native management of Allied Telesis TQ Series APs directly from the x930 CLI or GUI, eliminating a separate wireless controller.
• Tri-Authentication Security — Supports 802.1X, MAC-based, and web-based authentication simultaneously on the same port for comprehensive endpoint access control.
• EPSR Ring Resilience — Ethernet Protection Switched Ring protocol delivers sub-50ms failover for ring topology access networks.
• 1RU Rack-Mountable Form Factor — Standard 19-inch rack installation, 1.7" height, suitable for IDF closets and data center racks.

Typical Applications

• Enterprise campus distribution layer connecting access switches to core infrastructure
• Collapsed core/distribution switch for mid-sized campus networks with fewer than 500 access ports
• Data center access switch with 10G uplinks to spine or core tier
• Multi-building enterprise networks using VCStack LD over long-distance fiber
• Unified wired and wireless management environments with Allied Telesis TQ Series APs
• High-availability deployments requiring redundant power with zero downtime maintenance

Technical Specifications

Frequently Asked Questions

Q: How many units can be stacked with VCStack?

The x930 Series supports VCStack configurations of up to eight switches, managed as a single logical device. Each unit contributes up to 160 Gbps of stacking bandwidth. VCStack LD extends stacking over long-distance fiber links between buildings or sites.

Q: Does the AT-X930-28GSTX-901 support redundant power?

Yes. The switch includes two hot-swappable, load-sharing PSU bays. Both power supplies can run simultaneously and either one can be replaced without powering down the switch, provided the other is operational.

Q: What Layer 3 routing protocols are supported?

The x930-28GSTX supports static routing, RIP, OSPF, and BGP for Layer 3 forwarding, along with a comprehensive IPv6 feature set. Consult the Allied Telesis x930 Series software reference for the full protocol matrix.

Q: Can this switch manage wireless access points directly?

Yes. The Allied Telesis Wireless Manager feature allows the x930-28GSTX to provision, monitor, and manage Allied Telesis TQ Series 802.11 access points directly from the switch, without a separate wireless controller appliance.

Q: What is AMF and how does it benefit large deployments?

Allied Telesis Management Framework (AMF) provides automated network management across all AMF-enabled devices. It automates configuration backup, zero-touch device replacement, and network-wide software upgrades — reducing manual effort in large distributed networks.

Q: Is the x930-28GSTX compatible with SDN or OpenFlow?

The x930 Series is designed for SDN readiness and supports OpenFlow v1.3. This allows integration with SDN controllers for programmable forwarding plane control in environments requiring software-defined network policies.
