Allied Telesis AT-X510L-28GP-90 – 24-Port PoE+ Gigabit Switch with SFP Uplinks

Product Overview

The Allied Telesis x510L PoE+ Gigabit switch delivers 24-port 10/100/1000Base-T Power over Ethernet Plus (PoE+) connectivity with four 1G SFP uplink slots and a fixed internal power supply in a 1U managed Layer 3 chassis. Engineered for enterprise campus access and edge deployments, the AT-X510L-28GP-90 supports IEEE 802.3at PoE+ to power IP phones, wireless access points, IP cameras, and other PoE-enabled devices directly from the switch. IT managers deploying unified wired and wireless access infrastructure will find this switch well suited to building access layers requiring centralized power delivery and advanced network management.

Product Description

The AT-X510L-28GP-90 is part of Allied Telesis's x510L series — a scalable family of Layer 3 switches designed for demanding enterprise network edge and access deployments. All 24 RJ-45 access ports deliver 10/100/1000Base-T connectivity with full IEEE 802.3at PoE+ support, providing up to 30W per port for powering wireless access points, IP surveillance cameras, VoIP phones, and other PoE+ compliant devices. Four SFP/SFP+ uplink slots connect the switch to distribution or core switches over fiber or copper SFP transceivers. The switch runs AlliedWare Plus and supports Allied Telesis Management Framework (AMF), enabling automated provisioning, centralized backup, and zero-touch recovery. EPSRing and G.8032 ERPS protocols provide fast-failover resilient ring networking with sub-50ms recovery times. OpenFlow v1.3 certification makes the x510L-28GP suitable for software-defined networking (SDN) deployments, while IPv6 Ready certification supports government and future-proofed network designs. Active Fiber Monitoring (AFM) secures fiber connections against unauthorized physical access. VCStack support enables stacking for high-availability access deployments. Available from Creation Networks with full pre-sale and post-sale support.

Frequently Asked Questions

Q: What is the total PoE power budget of the AT-X510L-28GP-90?

The AT-X510L-28GP-90 has a fixed internal PSU. For precise total PoE power budget figures, refer to the Allied Telesis x510L series datasheet or contact Creation Networks for pre-sale technical assistance.

Q: Does the switch support IEEE 802.3af (15.4W) PoE devices in addition to 802.3at PoE+?

Yes. The PoE+ ports are backward compatible with IEEE 802.3af (PoE) devices that draw up to 15.4W, as well as 802.3at PoE+ devices drawing up to 30W per port.

Q: Can I use the SFP uplink slots for 10G connections?

The four uplink slots accept both 1G SFP and 10G SFP+ transceivers (dual-speed SFP+), allowing you to connect to distribution switches at either 1G or 10G depending on the transceiver installed.

Q: Is the x510L-28GP-90 OpenFlow capable for SDN deployments?

Yes. The AT-X510L-28GP-90 is certified for OpenFlow v1.3, the leading SDN protocol standard, making it suitable for software-defined network deployments managed by an OpenFlow controller.

Q: Does this switch require a separate PoE injector or midspan for PoE devices?

No. All 24 RJ-45 access ports deliver PoE+ natively from the switch's integrated PSU, eliminating the need for external PoE injectors or midspan equipment.

Q: Is the AT-X510L-28GP-90 suitable for government network deployments?

Yes. The switch is IPv6 Ready approved for government network compliance and supports AMF-based management for secure, auditable network operations.

Q: Where can I purchase the AT-X510L-28GP-90?

The AT-X510L-28GP-90 is available from Creation Networks at creationnetworks.net. Contact us for volume pricing, PoE power budget calculations, and configuration recommendations.
