Hardware Installation

WARNING: FAILURE TO PROVIDE PROPER VENTILATION MAY CAUSE FIRE HAZARD. KEEP AT LEAST 20 MM OF CLEARANCE NEXT TO THE VENTILATION HOLES FOR ADEQUATE AIRFLOW.

Wall Mounting

Grounding the EdgeRouter (Recommended)

The Power Cord grounds the device; however, you can add optional ESD grounding for enhanced ESD protection.

  1. Attach a screw (not included) to secure a ground wire (not included) to the Grounding Point.

  2. Secure the other end of the ground wire to a grounding block.

Connecting Power

Connect the Power Cord to the Power port and a power outlet.

Accessing the EdgeOS Configuration Interface

The EdgeOS® configuration interface can be accessed via DHCP or static IP address assignment. By default, eth1 is set up as a DHCP client, while eth0 is assigned a static IP address of 192.168.1.1. To configure the EdgeRouter, proceed to the appropriate section: DHCP or “Static IP Address”.

DHCP

  1. Connect an Ethernet cable from eth1 on the EdgeRouter to a LAN segment that has an existing DHCP server.

  2. To check the IP address of the EdgeRouter, use one of the following methods:
    • Set up the DHCP server to provide a specific IP address to the EdgeRouter based on its MAC address (on the label).
    • Let the EdgeRouter obtain an IP address and then check the DHCP server to see which IP address was assigned.
  3. Launch your web browser. Enter the appropriate IP address in the address field. Press enter (PC) or return (Mac).
  4. Enter ubnt in the Username and Password fields. Read the Ubiquiti License Agreement, and check the box next to I agree to the terms of this License Agreement to accept it. Click Login.

The EdgeOS Configuration Interface will appear, allowing you to customize your settings as needed. For more information, refer to the EdgeOS User Guide, which is available at ui.com/download/edgemax

Static IP Address

  1. Connect an Ethernet cable from the Ethernet port on your computer to the port labeled eth0 on the EdgeRouter.

  2. Configure the Ethernet adapter on your host system with a static IP address on the 192.168.1.x subnet.
  3. Launch your web browser. Type https://192.168.1.1 in the address field. Press enter (PC) or return (Mac).
  4. Enter ubnt in the Username and Password fields. Read the Ubiquiti License Agreement, and check the box next to I agree to the terms of this License Agreement to accept it. Click Login.
