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.
System Requirements
Linux, Mac OS X, or Microsoft Windows 7/8/10
Java Runtime Environment 1.6 (1.8 or newer recommended)
Web Browser: Google Chrome (Other browsers may have limited functionality.)
UniFi Controller software v4.8.5 or newer (available at: ui.com/download/unifi)

Power Port
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
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.
