Allied Telesis AT-X930-52GPX-B1 – 48-Port PoE+ Stackable Switch Dual PSU

Product Overview

The Allied Telesis x930 48-port PoE+ stackable switch (AT-X930-52GPX-B1) is a fully managed Layer 3 switch delivering 48 x 10/100/1000Base-T PoE+ access ports, 4 SFP+ 10G uplink slots, and dual hot-swappable power supplies in a 1U rack-mountable form factor. Engineered for enterprise campus distribution and access layer deployments, this redundant PSU PoE switch provides the reliability and port density required for large-scale wired and wireless network infrastructure. It supports VCStack stacking of up to eight units, Allied Telesis AMF network automation, and SDN readiness with OpenFlow v1.3.

Product Description

The AT-X930-52GPX-B1 is the standard commercial variant of Allied Telesis’s x930-52GPX platform — a high-density x930 PoE+ enterprise switch designed for the distribution and aggregation layer of enterprise campus networks. All 48 access ports support IEEE 802.3at PoE+ at up to 30W per port, enabling deployment of IP phones, 802.11ac/ax wireless access points, IP surveillance cameras, and other powered devices at scale without separate power injectors. The four SFP+ uplink slots accept 10GBase-SR, 10GBase-LR, and DAC connections, providing high-bandwidth links to core switching and routing equipment. Dual hot-swap power supply bays allow load-sharing redundant PSU operation — a defining feature of this x930 PoE+ enterprise switch — ensuring that a PSU failure or planned replacement does not interrupt network or PoE services. Allied Telesis VCStack technology allows up to eight x930 units to form a single logical switch with up to 160 Gbps of stacking bandwidth per unit, with near-hitless online stack reconfiguration supporting maintenance without downtime. VCStack LD (Long Distance) extends stacking across fiber links for distributed campus environments where switches are located in separate buildings. The switch’s AMF (Autonomous Management Framework) integration automates network-wide provisioning, firmware updates, configuration backups, and zero-touch replacement of failed devices. AMF Guestnode extends management visibility to non-Allied Telesis devices such as IP phones and cameras on the network edge. EPSRing and G.8032 Ethernet Ring Protection provide sub-50ms resilient failover for ring topology deployments. The AT-X930-52GPX-B1 supports OpenFlow v1.3 for Software Defined Networking integration, Microsoft Network Load Balancing (MS NLB), and a comprehensive IPv6 feature set — making this hot-swap power supply switch an investment that supports evolving network architectures.

Frequently Asked Questions

Q: What is the maximum PoE budget for the AT-X930-52GPX-B1?

The PoE budget depends on the power supply modules installed. The x930-52GPX platform supports dual hot-swappable PSUs in a load-sharing configuration. Contact Creation Networks at creationnetworks.net for PSU part numbers and total PoE budget calculations based on your deployment requirements.

Q: Can the dual PSUs be replaced while the switch is in operation?

Yes. The AT-X930-52GPX-B1 supports hot-swappable power supply modules. Either PSU can be removed and replaced without powering down the switch or interrupting network and PoE services, which is essential for enterprise environments with uptime requirements.

Q: How does VCStack stacking work on the AT-X930-52GPX-B1?

VCStack allows up to eight x930 switches to operate as a single logical device with a unified management plane. The stack uses the SFP+ or expansion module ports for stacking interconnects, supporting up to 160 Gbps of stacking bandwidth per switch. VCStack LD extends this over fiber links for distributed campus deployments.

Q: Is this switch compatible with Allied Telesis wireless access points?

Yes. The AT-X930-52GPX-B1 integrates with Allied Telesis TQ Series access points via the Wireless Manager feature. When combined with AMF, administrators can manage the entire wired and wireless infrastructure from a single platform, reducing operational complexity in enterprise Wi-Fi deployments.

Q: Does this switch support OpenFlow or SDN?

Yes. The AT-X930-52GPX-B1 supports OpenFlow v1.3 for Software Defined Networking integration, allowing it to operate under an SDN controller for centralized, programmable traffic management.

Q: What security features are included?

The switch includes tri-authentication for end-point access control, loop guard for cabling mistake detection, protection against common network attacks, and secure management options including SSH and SNMPv3.

Q: Where can I purchase the AT-X930-52GPX-B1?

The AT-X930-52GPX-B1 is available at Creation Networks (https://creationnetworks.net), an authorized Allied Telesis reseller specializing in enterprise and commercial networking equipment.
