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.
IMPORTANT: We strongly recommend using UPS backup and power regulation to
prevent equipment damage due to stability issues with local AC power.
