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:

Button Description
Reset
There are two methods to reset the
EdgeRouter Infinity to factory defaults:
• Runtime reset (recommended) The
EdgeRouter Infinity should be running
after bootup is complete. Press and hold
the Reset button for about 10seconds
until the LED of port eth0 starts flashing
and then becomes solidly lit. After a few
seconds, the LED will turn off, and the
EdgeRouter Infinity will automatically
reboot.
Note: To press the Reset button,
insert a straightened paper clip (or
similar object) into the hole shown
above. Do not use an object that
can break and become lodged in
the hole.
• Power-on reset Disconnect the Power
Cords from the EdgeRouter Infinity.
Press and hold the Reset button while
connecting the Power Cords to the
EdgeRouter Infinity. 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
The EdgeRouter Infinity can be placed on a horizontal surface,
mounted on a wall, or mounted in a rack.
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 Mounting Brackets to the EdgeRouter Infinity
using the eight Bracket Screws.
2. Attach the EdgeRouter Infinity to the rack using the four
Mounting Screws. (If the rack has square slots, then use the
Cage Nuts with the Mounting Screws.)

3. Connect the Power Cord to one PSU Power Port.
4. Connect the other end of the Power Cord to a power outlet.
5. Repeat steps 3-4 to connect power to the second
PSUPower Port.

Connecting SFP+
1. Remove the protective plug covering the SFP+ port.
2. Plug a compatible fiber module into the SFP+ port.
1000MbpsSM/SC20KM DDM
Tx1550nm/Rx1310nm
3. Connect the fiber optic cable to the fiber module. Then
connect the other end of the cable to another fiber device.
4. Repeat steps 1-3 to connect additional SFP+ ports.
Note: Use compatible fiber SFP+ modules with the
appropriate fiber optic cabling. For information about
compatible fiber SFP+ modules, visit:

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 a 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).
