Port 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. Then configure the following settings
as needed:
• Baud rate 115200
• Data bits 8
• Parity NONE
• Stop bits 1
• Flow control NONE
DC Input The 25VDC input can connect a redundant or
stand-alone DC power source (not included) with
minimum power: 25W (US-24) or 56W (US-48), 25
to 16V, and 2.5 mm DC power inline connector.
Note: You can use the redundant DC
power source as a hot spare; if the internal
AC/DC power supply no longer provides
power, then the EdgeSwitch Lite will
switch to the DC power source without
interrupting its operation.
Power Connect the included Power Cord to the
Powerport.

Hardware Installation
The UniFi Switch should be placed on a horizontal surface.
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.
WARNING: To reduce the risk of fire or electric shock, do
not expose the UniFi Switch to rain or moisture.
Mounting in a Rack (Optional)
1. Attach the Rack-Mount Brackets to the UniFi Switch using
the eight Bracket Screws.
2. Attach the UniFi Switch to the rack using the four Mounting
Screws. (If the rack has square slots, then use the Cage Nuts
with the Mounting Screws.)

Connecting Power
1. Connect the Power Cord to the power port on the back of
the UniFi Switch.
2. Plug the Power Cord into a power outlet.

Connecting Ethernet
1. Connect an Ethernet cable from your DHCP server or LAN

2. Connect your computer or host system and other devices
to the other ports on the UniFi Switch.

Using SFP Ports
To use an SFP port:
1. Remove the dust plug covering the SFP port.
2. Insert a compatible fiber SFP module into the SFP port.
1000MbpsSM/SC20KMDDM
Tx1550nm/Rx1310nm
3. Connect the fiber optic cable to the fiber SFP module.
