TERMS OF USE: All Ethernet cabling runs must use CAT5 (or above). It is the customer’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:
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
Front Panel Ports

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 from the Power Adapter. Press and
hold the Reset button while connecting
the power (refer to Connecting Power for
details). Keep holding the button until
the LED for port eth3 starts flashing and
then stops flashing after a few seconds.

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.
Rack Mounting
1. Slide the EdgeRouter into the Mounting Bracket and secure
it using the eight Bracket Screws.
2. Attach the Mounting Bracket and EdgeRouter to the rack
using the four Mounting Screws. (If the rack has square slots,
use the Cage Nuts with the Mounting Screws.)
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 100 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.
100 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 the Ground Screw 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.
