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.)

SFP2
Note: Keep 20 mm of clearance next to the
ventilation holes for adequate airflow.

3. Connect the other end of the Power Cord to a power outlet.
Connecting Ethernet
1. Connect an Ethernet cable from your computer or host
system to any port of UniFi Switch.

2. Connect Ethernet cables from the Ethernet ports of your
devices to the other numbered ports of the UniFi Switch.
Note: The PoE settings for ports 1-24 are set to
auto‑sensing PoE+ by default, so 802.3af/at devices
can be plugged in and automatically receive PoE. For
instructions on how to enable 24V passive PoE, refer
to the Configuring PoE Settings section.

Using SFP Ports
To use an SFP port:
1. Remove the protective plug covering the SFP port.
2. Plug a compatible fiber module into the SFP port.
