Interface Description
Console
RJ45 serial console port for Command
Line Interface (CLI) management. Use a
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
Ethernet

Interface Description
Reset
There are two methods to reset the
EdgeRouter Lite to factory defaults:
• Runtime reset (recommended) The
EdgeRouter Lite should be running after
bootup is complete. Press and hold the
Reset button for about 10seconds until
the right LED on port eth2 starts flashing
and then becomes solidly lit. After a
few seconds, the LED will turn off, and
the EdgeRouter Lite will automatically
reboot.
• Power-on reset Disconnect the Power
Cord from the Power Adapter. Press and
hold the Reset button while connecting
the Power Cord to the Power Adapter.
Keep holding the button until the right
LED on port eth2 starts flashing and then
stops flashing after a few seconds.

Hardware Installation
Mount the EdgeRouter Lite on a wall or place it on top of a
bench.
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.
Cabling Requirements
• 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 Lite to rain or moisture.
Note: Although the cabling can be located outdoors,
the EdgeRouter Lite itself should be housed inside a
protective enclosure.

Wall Mounting
To mount the EdgeRouter Lite on a wall, you will need a drill, a
6mm drill bit, and a Phillips screwdriver.
1. Use a 6 mm drill bit to drill two holes 100 mm apart.
2. Insert the Screw Anchors into the holes. Use a Phillips
screwdriver to secure a 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 Lite in a
vertical orientation.
3. Position the EdgeRouter Lite with the Ethernet ports
facing down. Place the wall‑mount slots of the EdgeRouter
Lite over the screw heads on the wall. Then slide the
EdgeRouter Lite down to lock it into place.
12VDC

Grounding the EdgeRouter Lite (Recommended)
The EdgeRouter Lite is grounded through the Power Adapter;
however, you can add optional ESD grounding for enhanced
ESD protection.
1. Loosen the grounding 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 Adapter to the Power port.

2. Connect the Power Cord to the Power Adapter. Connect the
other end of the Power Cord to a power outlet.
Accessing the EdgeOS Configuration Interface
1. Connect an Ethernet cable from the Ethernet port of your
computer to the port labeled eth0 on the EdgeRouter Lite.
2. Configure the Ethernet adapter on your host system
with a static IP address on the 192.168.1.x subnet
(e.g.,192.168.1.100).
3. Launch your web browser. Type https://192.168.1.1 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.
