Allied Telesis AT-GS980MX/28PSM-50 network switch Managed L3 Gigabit Ethernet (10/100/1000) Power over Ethernet (PoE) 1U Grey

The Allied Telesis AT-GS980MX/28PSM-50 is a managed Layer 3 Gigabit Ethernet switch in a 1U rack-mount form factor. It provides 20 Gigabit RJ-45 ports plus 4 SFP+ modules, 10G support, and a switching capacity of 160 Gbit/s with a MAC address table of 16,000 entries. The switch supports Power over Ethernet (PoE/PoE+/PoE++) and a broad set of IEEE networking standards, making it suitable for edge deployments that require high-capacity, resilient connectivity and centralized management.

Advantages

This model combines Multi-Gigabit port support and PoE options to connect and power devices such as IP phones and wireless access points while enabling upgrades over existing cabling with 2.5G and 5G speeds. Higher-power PoE++ capability on specific models supports demanding devices like outdoor PTZ cameras. The switch can form a resilient stack using VCStack™ and reduce operational complexity through Autonomous Management Framework™ Plus (AMF Plus). Its 1U rack design and 10G-capable SFP+ modules deliver compact, scalable performance for network edge and rack deployments.

Suitable for

• Enterprise and campus network access layer
• Powering and connecting IP phones, wireless APs and surveillance cameras
• Edge aggregation where 10G uplinks or Multi‑Gigabit downlinks are required
• Distributed sites requiring stacking and centralized management

How to use

Install the AT-GS980MX/28PSM-50 in a standard 19" rack using the included mounting hardware. Connect network uplinks to the SFP+ ports for 10G aggregation and use the Gigabit RJ-45 ports for edge devices. Configure stacking using VCStack™ if multiple units are deployed to create a single logical switch, and enable AMF Plus to centralize configuration and monitoring. Apply PoE to compatible ports to power devices; verify PoE budget and per-port power limits when connecting high-power equipment.

Recommendations

For reliable operation, plan PoE power budgets before deployment, use approved SFP/SFP+ transceivers for 10G links, and keep firmware updated to benefit from AMF Plus and stacking stability features. Ensure adequate rack ventilation and follow manufacturer guidelines for outdoor device power requirements when using PoE++.
