Installation Requirements
• Phillips screwdriver
• 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 PSU.
We recommend that you protect your networks from
harmful outdoor environments and destructive ESD events
with industrial-grade, shielded Ethernet cable 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
WARNING: FAILURE TO PROVIDE PROPER VENTILATION
MAY CAUSE FIRE HAZARD. KEEP AT LEAST 20 MM OF
CLEARANCE NEXT TO THE VENTILATION HOLES FOR
ADEQUATE AIRFLOW.
WARNING: To reduce the risk of fire or electric shock, do
not expose the UniFi Switch to rain or moisture.
1. Connect the Power Cord to the Power port of the PSU
Module.
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.)
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 the UniFi Switch.
2. Connect Ethernet cables from the Ethernet ports of your
devices to the other numbered ports of the UniFi Switch.
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.
1000Mbps SM/SC 20KM DDM
Tx1550nm/Rx1310nm
3. Connect a fiber optic cable to the fiber module. Then
connect the other end of the cable to another fiber device.
Using SFP+ Ports (US-L2-48-POE only)
To use an SFP+ port:
1. Remove the protective plug covering the SFP+ port.
2. Plug a compatible fiber module into the SFP+ port.
1000Mbps SM/SC 20KM DDM
Tx1550nm/Rx1310nm
3. Connect a fiber optic cable to the fiber module. Then
connect the other end of the cable to another fiber device.
