With redundant PSU support, Continuous PoE, and a comprehensive security feature set, it is a reliable access and distribution layer platform for medium to large enterprise environments.

Product Description

The AT-X930-52GPX-B91 is part of Allied Telesis’s x930 Series — a family of advanced Gigabit Layer 3 stackable switches positioned for distribution and core network roles in enterprise campus and commercial environments. As an x930 series enterprise switch, it combines high port density with full Layer 3 routing capability, supporting IPv4 and IPv6 with OSPF, BGP, and RIP for versatile deployment across access, distribution, and aggregation layers. All 48 10/100/1000Base-T access ports deliver IEEE 802.3at PoE+ at up to 30W per port, enabling support for IP phones, wireless access points, and IP cameras without external power injectors. The SFP+ expansion slots provide 10 Gigabit Ethernet uplink capacity for aggregation to core switching infrastructure. Allied Telesis VCStack technology allows up to eight x930 units to operate as a single logical switch with up to 160 Gbps of stacking bandwidth, while VCStack LD enables stack formation over fiber for distributed building topologies. Continuous PoE ensures connected powered devices maintain uninterrupted power during stack failover events, a critical requirement in VoIP and physical security deployments. Redundant power supply support ensures high availability for environments that cannot tolerate PSU-related downtime. Network management is handled through Allied Telesis AMF, Vista Manager EX, and the Device GUI — providing graphical monitoring and AMF-driven automation for both wired and wireless network infrastructure. The AT-X930-52GPX-B91 x930 series enterprise switch also supports G.8032 Ethernet Ring Protection and EPSRing for resilient ring topology failover, Precision Time Protocol (PTP) Transparent Mode, and Active Fiber Monitoring for proactive link health diagnostics.

Key Features

Frequently Asked Questions

Q: What is the difference between the AT-X930-52GPX-B91 and the AT-X930-52GPX-B1?

Both are commercial variants of the x930-52GPX platform. The -B1 and -B91 designations reflect different regional power supply configurations and bundled PSU options. Both support dual hot-swappable PSUs, 48 PoE+ ports, 4 SFP+ uplinks, and the full x930 Series feature set. Contact Creation Networks at creationnetworks.net for region-specific procurement guidance.

Q: How many switches can be stacked on the AT-X930-52GPX-B91?

Up to eight x930 Series switches can form a single VCStack with up to 160 Gbps of stacking bandwidth per unit. VCStack LD allows stacks to extend over fiber links for deployments across multiple buildings or campuses.

Q: Does this switch support IPv6 routing?

Yes. The AT-X930-52GPX-B91 includes a comprehensive IPv6 feature set with full Layer 3 routing support including OSPFv3, BGP, and static IPv6 routes, making it suitable for networks transitioning to or running native IPv6.

Q: What happens to PoE-powered devices during a stack failover?

The Continuous PoE feature ensures that PoE delivery to connected devices is maintained during stack failover events. This is critical for IP phones, access control panels, and surveillance cameras that require uninterrupted power during network reconfiguration.

Q: What security features does the AT-X930-52GPX-B91 include?

The switch includes tri-authentication (802.1X, MAC-based, and web-based authentication) for comprehensive end-point access control, loop guard, traffic type controls, and protection against network attacks including DoS. Secure management is available via SSH and SNMPv3.

Q: Is this switch compatible with Allied Telesis AMF networks?

Yes. The AT-X930-52GPX-B91 fully supports Allied Telesis AMF (Autonomous Management Framework), enabling it to participate in network-wide automated management, zero-touch provisioning, and disaster recovery alongside other AMF-compatible Allied Telesis devices.
