UniFi Pro Max 16 – 16-Port 2.5G Layer 3 Switch with Etherlighting

The UniFi Pro Max 16 is a versatile 16-port Layer 3 switch designed to deliver high-speed, reliable connectivity with advanced network visibility. It features 12 GbE RJ45 ports, 4 × 2.5 GbE RJ45 ports, and 2 × 10G SFP+ uplinks, making it a flexible choice for a wide range of UniFi deployments.

Equipped with Ubiquiti’s Etherlighting technology, the Pro Max 16 provides port illumination to indicate location, speed, link status, and native VLAN or network assignment when paired with UniFi Etherlighting Patch Cables. This enhances troubleshooting and visibility in both rack-mounted and distributed environments.

Its silent, fanless cooling system ensures quiet operation, while versatile mounting options - desktop, wall, or rack (with accessory) - allow for flexible installation. Fully managed through the UniFi Network application, the Pro Max 16 is well-suited to offices, hospitality, education, and other environments requiring dependable, high-capacity switching.
