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

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.
