Allied Telesis AT-X510DP-52GTX – Stackable Top-of-Rack Data Center Switch

Product Overview

The Allied Telesis x510DP top-of-rack data center switch (AT-X510DP-52GTX) is a stackable gigabit edge switch designed for server and storage connectivity at the top-of-rack position in enterprise and colocation data centers. It provides 48 x 10/100/1000T copper ports for server connections and 4 x 10G SFP+ uplink ports for high-speed connectivity to aggregation or core switches. Dual hot-swappable AC or DC load-sharing power supplies with reverse airflow and VCStack virtual chassis stacking make the AT-X510DP-52GTX a resilient choice for data center applications requiring uninterrupted operation. Enterprise network engineers looking for a cost-effective Allied Telesis x510DP top-of-rack data center switch with VCStack stacking, redundant PSUs, and AMF management integration will find the X510DP-52GTX purpose-built for high-density server edge deployments.

Product Description

The AT-X510DP-52GTX is engineered specifically for data center top-of-rack deployments where server density, power redundancy, and airflow management are critical design requirements. The 48 x 10/100/1000T copper ports provide high-density 1G server connectivity, while four 10G SFP+ uplinks connect to aggregation-layer switches or storage networks. The DP suffix designates the dual-PSU, reverse-airflow data center variant: both the power supplies and fan modules support front-to-rear airflow direction, aligning with standard hot-aisle/cold-aisle data center cooling architectures. Load-sharing redundant PSUs accept either AC or DC power, with hot-swap capability ensuring PSU replacement without service interruption. Allied Telesis VCStack stacks multiple x510DP units into a single virtual chassis with no single point of failure, providing a resilient active-active aggregation tier at the server edge. VCStack distributes logical switch management across all member units, so the failure of any single switch does not interrupt server-to-network connectivity for hosts connected to other stack members. The switch runs AlliedWare Plus, providing a consistent CLI and management interface across the Allied Telesis portfolio, with support for LACP link aggregation, MSTP spanning tree, VLAN trunking, QoS, and ACL-based traffic control. Autonomous Management Framework (AMF) integration enables zero-touch auto-backup and auto-provisioning, simplifying the replacement of failed units in the data center without manual configuration. Vista Manager and the Device GUI provide graphical monitoring of port status, VLAN configuration, and stack health. The x510DP series supports IPv6 and meets standard data center layer-2 forwarding requirements for server and storage connectivity.

Key Features

• 48 x 10/100/1000T Copper Ports — High-density RJ-45 server connectivity for top-of-rack deployments connecting 1G servers and storage appliances.
• 4 x 10G SFP+ Uplink Ports — High-speed fiber uplinks to aggregation or core switches; supports a range of Allied Telesis SFP+ transceivers for multi-mode or single-mode fiber.
• Dual Hot-Swap Load-Sharing PSUs (AC or DC) — Redundant power supplies with hot-swap replacement ensure uninterrupted operation during PSU maintenance or failure.
• Reverse Airflow (Front-to-Rear) — Airflow direction aligns with hot-aisle/cold-aisle data center cooling standards, preventing recirculation of hot exhaust air.
• VCStack Virtual Chassis Stacking — Multiple units operate as a single logical switch with no single point of failure; stack link failure triggers automatic failover without server connection loss.
• AlliedWare Plus Operating System — Consistent CLI and management interface supporting LACP, MSTP, QoS, ACLs, VLAN trunking, and IPv6 across the Allied Telesis product portfolio.
• AMF Zero-Touch Management — Auto-backup and auto-provisioning enable replacement of failed units without on-site manual configuration, reducing mean time to recovery in the data center.
• 1U Rack-Mountable Form Factor — Standard 1U chassis fits all standard 19-inch data center equipment racks with minimal space consumption per server rack.
• Redundant Power Supply Support — Both AC and DC PSU variants available, supporting both commercial AC power and DC-powered data center environments.

Typical Applications

• Top-of-rack (ToR) server edge switching in enterprise, colocation, and private cloud data centers
• High-density 1G server aggregation with 10G uplinks to data center aggregation layer
• Storage area network (SAN) edge connectivity for iSCSI or NAS storage devices
• Virtualization host switching providing network connectivity for hypervisor-based server clusters
• AMF-managed data center networks requiring zero-touch provisioning and auto-recovery
• DC-powered data centers or environments with mixed AC/DC power infrastructure

Frequently Asked Questions

Q: What does the DP suffix mean in AT-X510DP-52GTX?

The DP suffix designates the Data center Power variant of the x510 series: dual hot-swappable load-sharing power supply bays and reverse (front-to-rear) airflow direction, both standard requirements for hot-aisle/cold-aisle data center rack installations. Standard x510 models ship with a single internal PSU and standard front-to-back airflow.

Q: How many units can be stacked with VCStack on the x510DP?

VCStack supports stacking of multiple x510DP units into a single virtual chassis. The exact maximum stack size for the x510DP series should be confirmed in the AlliedWare Plus software release notes or Allied Telesis product datasheet. Each stack member retains local switching capability, so failure of one unit does not interrupt traffic on other members.

Q: Does the AT-X510DP-52GTX support DC power?

Yes. The dual PSU bays support both AC and DC power supply modules, making the X510DP-52GTX suitable for telecommunications facilities and data centers that operate on -48V DC power infrastructure. AC and DC PSUs are ordered separately.

Q: What SFP+ transceivers are compatible with the 10G uplink ports?

The four 10G SFP+ uplink ports are compatible with Allied Telesis SFP+ transceivers including 10GBase-SR (multi-mode fiber), 10GBase-LR (single-mode fiber), and 10GBase-ER (extended-range single-mode). Direct-attach copper (DAC) cables are also supported for short-distance connections to aggregation switches. Verify third-party optic compatibility against the Allied Telesis transceiver compatibility matrix.

Q: Is the x510DP-52GTX suitable for use in an AMF-managed network?

Yes. The x510DP-52GTX runs AlliedWare Plus and supports full AMF integration, enabling auto-backup, auto-provisioning, and auto-recovery through Vista Manager or a designated AMF master device such as the VST-APL-10-60. AMF management significantly reduces the time required to replace a failed switch in a data center environment.

Q: Does this switch support Layer 3 routing?

The x510DP-52GTX is designed primarily as a Layer 2 top-of-rack switch. AlliedWare Plus supports static routing and basic Layer 3 forwarding on the x510 series. For full BGP4/OSPF data center routing, the x950 series with the Premium license is the recommended platform.

Q: Where can I order the AT-X510DP-52GTX?

The AT-X510DP-52GTX is available from Creation Networks at creationnetworks.net, an authorized Allied Telesis reseller. Creation Networks can assist with PSU selection, transceiver compatibility, and VCStack design for data center deployments.
