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)
48V (2-pair) PoE output is Off by default. Enabling PoE output (via the UniFi Network Application) requires 24W input power via PoE In or DC input.
RJ45 (Ports 1 - 8)
RJ45 ports support 10/100/1000 Ethernet connections.

Hardware Installation

Wall Mounting (Optional)

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

Connecting Ethernet

	WARNING: Before enabling PoE passthrough in the UniFi Network Application, 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 (if enabled).

Safety Notices

Read, follow, and keep these instructions.
Heed all warnings.
Only use attachments/accessories specified by the manufacturer.

	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 this product to rain or moisture.

	WARNING: Do not use this product in location that can be submerged by water.

	WARNING: Avoid using this product during an electrical storm. There may be a remote risk of electric shock from lightning.

Electrical Safety Information

Compliance is required with respect to voltage, frequency, and current requirements indicated on the manufacturer’s label. Connection to a different power source than those specified may result in improper operation, damage to the equipment or pose a fire hazard if the limitations are not followed.
There are no operator serviceable parts inside this equipment. Service should be provided only by a qualified service technician.
This equipment is provided with a detachable power cord which has an integral safety ground wire intended for connection to a grounded safety outlet.
1. Do not substitute the power cord with one that is not the provided approved type. Never use an adapter plug to connect to a 2-wire outlet as this will defeat the continuity of the grounding wire.
2. The equipment requires the use of the ground wire as a part of the safety certification, modification or misuse can provide a shock hazard that can result in serious injury or death.
3. Contact a qualified electrician or the manufacturer if there are questions about the installation prior to connecting the equipment.
4. Protective earthing is provided by Listed AC adapter. Building installation shall provide appropriate short-circuit backup protection.
5. Protective bonding must be installed in accordance with local national wiring rules and regulations.

Limited Warranty
