Hardware Overview

Front Panel

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 PoE Out port using the UniFi
Controller software. PoE passthrough supports 48V (2-pair).

Back Panel

Port	Description
Ground	Ancillary grounding point for enhanced ESD protection.
DC In	To power the switch by DC input, connect a 48V

power adapter to the 48VDC port.

Reset

Button

| This button serves two functions for the UniFi

Switch:

| • Restart Press and release the Reset button quickly.
| • Restore to Factory Default Settings Press and hold the Reset button for more than five seconds.

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.

Drill two 6 mm holes set 73.5 mm apart.
Insert a Screw Anchor into each hole, and fasten a Screw into each anchor.
Leave a clearance of approximately 3 mm between the screw head and the wall.
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.

Loosen the ground screw and secure a ground wire (not included) to the grounding point.
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.
a circuit board

Power by DC Input

Connect the Power Adapter to the 48VDC port on the back of the UniFi Switch.
Connect the Power Cord to the Power Adapter. Plug the Power Cord into a power outlet.

Connecting Ethernet

Connect an Ethernet cable from your DHCP server or LAN to any port 1 to 7.
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 on-screen instructions.

Note: If you already have UniFi Controller v5.3.x or newer installed, skip to the section, Adopting the UniFi Switch.
