Standard-sized, 19" wide rack with a minimum of 1U height available
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. For
more details, visit: ui.com/toughcable
Note: Although the cabling can be located outdoors, the UniFi Switch itself should be
housed inside a protective enclosure.

This button serves two functions for the UniFi Switch:
Press and release the Reset button to restart the device.
Press and hold the Reset button (for at least ve seconds) to restore the device to its
factory default settings.
Back Panel Ports
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 congure the following settings as needed:
Baud rate 115200
Data bits 8
Parity NONE
Stop bits 1
Flow control NONE
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 UniFi Switch will
switch to the DC power source without interrupting its operation .
Connect the included Power Cord to the Power port.
