TERMS OF USE: All Ethernet cabling runs must use CAT5 (or above). It is the professional
installer's responsibility to follow local country regulations, including operation within legal
frequency channels, output power, indoor cabling requirements, and Dynamic Frequency
Selection (DFS) requirements.

Installation Requirements
• Phillips screwdriver (for rack- or wall-mounting)
• Standard-sized, 19" wide rack with a minimum of 1U height
available (for rack-mounting)
• For indoor applications, use Category 5 (or above) UTP
cabling approved for indoor use.
• For outdoor applications, shielded Category 5 (or above)
cabling should be used for all wired Ethernet connections
and should be grounded through the AC ground of the
power supply.
We recommend that you protect your networks from
harmful outdoor environments and destructive ESD events
with industrial-grade, shielded Ethernet cable from Ubiquiti
Networks. For more details, visit:

WARNING: To reduce the risk of fire or electric shock,
do not expose the EdgeRouter to rain or moisture.
Note: Although the cabling can be located outdoors,
the EdgeRouter itself should be housed inside a
protective enclosure.

Hardware Overview

Interface Description
Console
RJ45 serial console port for Command
Line Interface (CLI) management. Use an
RJ45-to-DB9, serial console cable, also
known as a rollover cable, to connect the
Console port to your computer. (If your
computer does not have a DB9 port, then
you will also need a DB9 adapter.) Then
configure the following settings as needed:
• Baud rate 115200
• Data bits 8
• Parity NONE
• Stop bits 1
• Flow control NONE
USB Reserved for future use.

Button Description
Reset
There are two methods to reset the
EdgeRouter to factory defaults:
• Runtime reset (recommended) The
EdgeRouter should be running after
bootup is complete. Press and hold
the Reset button for about 10seconds
until the right LED on RJ45 port eth7
starts flashing and then becomes
solidly lit. After a few seconds, the LED
will turn off, and the EdgeRouter will
automaticallyreboot.
• Power-on reset Disconnect the Power
Cord from the EdgeRouter. Press and hold
the Reset button while connecting the
Power Cord to the EdgeRouter. The port
LEDs will light up in sequential order.
Keep holding the Reset button until the
LED on the last port starts flashing, and
then release the button.

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.
1. Attach the EdgeRouter to the rack using the four Mounting
Screws. (If the rack has square slots, then use the Cage Nuts
with the Mounting Screws.)
2. Connect the Power Cord to the Power port.

3. Connect the other end of the Power Cord to 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. The login screen will appear. 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
www.ubnt.com/download/edgemax
You can also manage your device using the Ubiquiti® Network
Management System. UNMS™lets you configure, monitor,
upgrade, and back up your devices using a single application.

Static IP Address
1. Connect an Ethernet cable from the Ethernet port of 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).
