Connecting to Your Network

The UNAS 2 can be connected to your network and powered in two ways:

• PoE++ (Power over Ethernet Plus Plus): Connect an Ethernet cable from a PoE++ compliant switch to the 2.5 GbE RJ45 port on the rear of the UNAS 2. This provides both network connectivity and power.
• Included 60W Adapter: If not using PoE++, connect the included 60W power adapter to the power input port on the rear of the UNAS 2, and then connect an Ethernet cable from your network to the 2.5 GbE RJ45 port.

Operating the UNAS 2

Once powered on and connected, the UNAS 2 operates within the UniFi ecosystem. It requires UniFi Drive Version 3.1.7 or later for full functionality. Mobile app support is available for iOS (v10.28.0+) and Android (v10.28.3+) devices, allowing remote management and access to your stored data.

The 1.47" color LCM display on the front panel provides essential status updates, while system LEDs offer quick visual indicators of operation and activity.
