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