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
• Drill with a 6 mm drill bit (for wall-mounting)
• Phillips screwdriver
• 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:
www.ubnt.com/toughcable
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

USB
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.
RJ45
(eth0-eth2)
RJ45 ports support 10/100/1000 Ethernet
connections.
SFP
(eth3)
SFP port is hot-swappable and supports
Gigabit fiber SFP modules.

Reset
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 10seconds until
the LED for port eth3 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. Press and hold the Reset button
while connecting the power (refer to
“Connecting Power” for details). The
port LEDs will light up in sequential order.
Keep holding the Reset button until the
System LED starts flashing blue and white,
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.
Wall Mounting
To mount the EdgeRouter on a wall, you will need a drill, a
6mm drill bit, and a Phillips screwdriver.
1. Use a 6 mm drill bit to drill two holes 125 mm apart.
2. Insert the Wall Mount Anchors into the holes. Use a Phillips
screwdriver to secure a Wall Mount Screw to each anchor.
Leave a clearance of approximately 3 mm between each
screw head and its anchor.
125 mm
3 mm
Note: You can also mount the EdgeRouter in a
vertical orientation.
3. Position the EdgeRouter with the Ethernet ports facing
down. Place the wall-mount slots of the EdgeRouter over
the screw heads on the wall. Then slide the EdgeRouter
down to lock it into place.
Grounding the EdgeRouter (Recommended)
The EdgeRouter is grounded through the Power Cord;
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
1. Connect the Power Cord to the Power port.
2. Connect the other end of the Power Cord to a power outlet.
Using SFP Ports
To use an SFP port:
1. Remove the protective plug covering the SFP port.
2. Plug a fiber SFP module into the SFP port.
