Hardware Overview
Front Panel
Ports 1-8
PoE OutPoE In
Port Description
Ports 1-8 RJ45 ports support 10/100/1000 Ethernet
connections.
PoE In
(Port 1)
Supports 802.3af/at or 48V Passive PoE to
power the switch and can provide 48V (2-pair)
PoE passthrough to port 8.
PoE Out
(Port 8)
PoE output is Off by default. Enabling PoE
output requires 24W input power via PoE In or
DC input.
The UniFi Switch may be powered by PoE through the PoE In
port or by DC input using a 48V power adapter.
PoE can be enabled on the PoEOut port using the UniFi
Controller software. PoE passthrough supports 48V (2-pair).

Ventilation Holes
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: The US-8 must not be stacked. Do not place it
on top of another switch. Do not place anything on top
of the US-8.
Hardware Installation
The UniFi Switch can be mounted on a vertical surface or
placed on a desktop. Follow the Wall Mounting instructions to
mount the switch using the included screws and anchors.
WARNING: To reduce the risk of fire or electric shock, do
not expose the switch to rain or moisture.
Wall Mounting
1. Drill two 6 mm holes set 73.5 mm apart.
73.5 mm
2. Insert a Screw Anchor into each hole, and fasten a Screw
into each anchor.
3. Leave a clearance of approximately 3mm between the
screw head and the wall.
3 mm
4. Mount the UniFi Switch by inserting the screw heads into
the mounting slots on the bottom of the switch. Then slide
the switch down to lock it in place.
Grounding (Recommended)
The UniFi Switch is grounded through the Power Adapter.
When powering the switch with PoE, ground the device by
connecting the ancillary ground.
1. Loosen the ground screw and secure a ground wire (not
included) to the grounding point.
2. Secure the other end of the ground wire to a grounding
block or other grounded structure.
Connecting Power
The UniFi Switch can be powered by PoE or DC input using the
Power Adapter.
Power by PoE
Connect an Ethernet cable from an 802.3af/at or 48V passive
PoE power source to the PoE In port.
Power by DC Input
1. Connect the Power Adapter to the 48VDC port on the back
of the UniFi Switch.
2. Connect the Power Cord to the Power Adapter. Plug the
Power Cord into a power outlet.
Connecting Ethernet
1. Connect an Ethernet cable from your DHCP server or LAN
to any port 1 to 7.
2. Connect your PoE device to port 8.
WARNING: Before enabling PoE passthrough in the
UniFi Controller, ensure that the connected PoE device
supports the PoE power (48V).
WARNING: When both PoE In and DC Input are
connected, the highest voltage power of the two will
immediately pass through to PoE Out.
Software Installation
Download and install the latest version of the UniFi Controller
software at downloads.ubnt.com/unifi and follow the
