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 outdoor networks
from the most brutal environments and devastating ESD
attacks with industrial‑grade shielded Ethernet cable,
TOUGHCable™, from Ubiquiti Networks. For more details,

visit: www.ubnt.com/toughcable

Note: Although the cabling can be located outdoors,

the UniFi Switch itself should be housed inside a
protective enclosure.

Hardware Installation

1. Connect the Power Cord to the Power port of the
UniFiSwitch.

2. Attach the UniFi Switch to the rack using the four Mounting

Screws. (If the rack has square slots, then use the Cage Nuts
with the Mounting Screws.)
