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.

Hardware Installation

IMPORTANT: Fanless switches must not be stacked. Do not place this UniFi Switch on top of another switch. Do not place anything on top of this UniFi Switch.
