Allied Telesis AT-X230-28GP-90 – 24-Port PoE+ Managed Gigabit Switch with 4x SFP

Product Overview

The Allied Telesis x230 24-port PoE+ managed switch (AT-X230-28GP-90) provides 24 ports of IEEE 802.3at PoE+ Gigabit Ethernet and 4 SFP uplink slots in a compact 1U rackmount form factor, making it an ideal wiring-closet and network-edge switch for SMB and enterprise campus deployments. Designed for organizations requiring a fully managed Gigabit PoE+ access switch with fiber uplinks, the x230-28GP delivers 56 Gbps of switching fabric and 41.7 Mpps forwarding rate with AlliedWare Plus management, AMF+ integration, and OpenFlow v1.3 SDN readiness. This switch also carries TAA compliance certification, qualifying it for US Government procurement. With a 370W maximum PoE power budget and support for up to 24 simultaneous PoE+ devices, the AT-X230-28GP-90 is a capable 24-port PoE+ switch for IP cameras, wireless APs, and VoIP phones in commercial buildings and campus wiring closets.

Product Description

The AT-X230-28GP-90 is the 28-port PoE+ model of the Allied Telesis x230 series, a line of Gigabit managed edge switches engineered for flexible deployment at the network access layer. All 24 copper RJ45 ports are PoE+-capable, providing up to 30W per port under IEEE 802.3at, with a maximum PoE budget of 370W to support dense deployments of wireless access points, IP surveillance cameras, VoIP handsets, and other powered devices. The 4 SFP uplink slots accept both 100/1000X SFPs, giving network engineers flexibility to choose between multimode or single-mode fiber uplinks depending on distance requirements to the distribution layer. The switch runs AlliedWare Plus, Allied Telesis’ enterprise-grade network operating system, providing a consistent CLI experience across all AlliedWare Plus platforms and reducing training overhead. AMF+ (Autonomous Management Framework Plus) automates configuration backup, zero-touch provisioning, and node recovery across the entire campus network, reducing operational costs. Security is comprehensive: IEEE 802.1X port-based authentication with dynamic VLAN assignment enforces access policies, while DHCP snooping, STP root guard, BPDU protection, and ACLs defend against common Layer 2 attacks. The x230-28GP supports Energy Efficient Ethernet (EEE), automatically reducing port power consumption during low-traffic periods to lower operating costs. Loop detection and thrash limiting prevent network storms from propagating when cabling errors create loops. The switch’s 56 Gbps non-blocking switching fabric ensures wire-rate forwarding across all 28 ports simultaneously, with no internal congestion under full load. The x230-28GP-90 variant includes a 90-day warranty extension and ships with rack mounting hardware for 1U installation in standard 19-inch equipment racks.

Frequently Asked Questions

Q: What is the total PoE power budget of the AT-X230-28GP?

The x230-28GP has a maximum PoE power budget of 370W across all 24 PoE+ ports. It can support up to 24 ports simultaneously at 15W (IEEE 802.3af) or up to 12 ports at 30W (IEEE 802.3at PoE+). Actual device mix determines total draw.

Q: Are the 4 SFP uplink ports shared with copper ports?

No. The 4 SFP slots on the x230-28GP are independent and not shared with any copper ports, providing a full 28 active ports simultaneously (24 copper + 4 SFP).

Q: Is the AT-X230-28GP-90 TAA compliant?

Yes. The AT-X230-28GP-90 carries Trade Agreements Act (TAA) compliance certification, making it eligible for US Government and federal agency procurement under GSA schedules.

Q: What SFP modules are compatible with the uplink slots?

The SFP slots accept 100/1000X SFPs supporting both 100FX (Fast Ethernet fiber) and 1000Base-SX/LX/ZX (Gigabit fiber) transceivers. Allied Telesis branded SFPs are recommended for full compatibility and support.

Q: Does the x230-28GP support stacking?

The x230 series supports Allied Telesis AMF (Autonomous Management Framework) for logical stacking and unified management across multiple switches, but does not use proprietary hardware stacking cables.

Q: Can the x230-28GP be managed via a web browser?

Yes. AlliedWare Plus includes a full-featured web-based GUI for switch management, monitoring, and configuration, in addition to CLI access via SSH/Telnet and SNMP.

Q: What rack mounting options are available?

The AT-X230-28GP-90 ships with a rack mount kit for standard 19-inch 1U rack installation. A desktop stand kit (AT-STND-J03) is also available separately.

Q: Where can I purchase the AT-X230-28GP-90?
