Mounting Bracket to help secure the UniFi AP. (This is described
further in the Mounting Bracket section.)
Ethernet This Gigabit Ethernet port is used to connect the
power and should be connected to the LAN and DHCP server.
Power can be provided by a Ubiquiti Networks UniFi Switch with
PoE or Gigabit PoE adapter (included with single-pack only).
Reset The Reset button serves two functions for the UniFi AP:
• Restart Press and release the Reset button quickly.
• Restore to Factory Default Settings Press and hold the
Reset button for more than five seconds.
Alternatively, the UniFi AP may be reset remotely via a Reset
button located on the bottom of the Gigabit PoE adapter.
Cable Feed Plug If your Ethernet cable feeds along the
mounting surface, remove the Cable Feed Plug.

Note: If you need to remove the UniFi AP from the
Mounting Bracket, insert a paper clip in the Slot to release
the Locking Tab and turn the UniFi AP counterclockwise.

Hardware Installation
The UniFi AP can be mounted on the wall or ceiling. Perform
the steps for the appropriate installation:
Wall Mount
1. Position the Mounting Bracket at the desired location on
the wall with the arrow pointing up.
2. Use a pencil to mark the four mounting holes. Use a 6 mm
drill bit to drill the mounting holes.
Arrow
3. If your Ethernet cable feeds through the wall, then cut or
drill a circle approximately 18 mm in diameter. Then feed
the CAT5/6 cable through the hole.
25 mm
Note: 25 mm is the distance from the center of the
bottom mounting hole to the center of the cable hole.

4. Insert the Screw Anchors into the 6 mm holes. Secure the
Mounting Bracket to the wall by inserting the Screws into
the anchors.
5. If the Ethernet cable runs along the mounting surface,
remove the Cable Feed Plug.

6. Connect the Ethernet cable to the Ethernet port.
7. Align the arrow on the UniFi AP with the arrow on the
Locking Tab of the Mounting Bracket.

8. Ensure that the UniFi AP is firmly seated on the Mounting
Bracket. Turn the UniFi AP clockwise until it locks into place
and the Locking Tab fits securely into the Locking Notch.

Ceiling Mount
1. Remove the ceiling tile.
2. Place the Ceiling Backing Plate in the center of the ceiling
tile. Mark the four mounting screw holes.
3. Mark a hole approximately 18 mm in diameter for the
Ethernet cable feed.
25 mm
Note: 25 mm is the distance from the center of the
bottom mounting hole to the center of the cable hole.
4. Use a 3 mm drill bit to drill the screw holes, and cut or drill
the hole for the Ethernet cable feed.

5. Insert the Flat Head Screws through the Mounting Bracket,
ceiling tile, and Ceiling Backing Plate. Fasten the screws
using the Keps Nuts. Then feed the Ethernet cable through
the 18 mm hole.

6. Connect the Ethernet cable to the Ethernet port.
7. Align the arrow on the UniFi AP with the arrow on the
Locking Tab of the Mounting Bracket.

Connecting Power over Ethernet
The single-pack of the UAP-AC-LITE includes one Gigabit
PoE adapter. For multi-pack units, we recommend using a
UniFiSwitch with PoE.
1. Connect the Ethernet cable from the device to the
adapter’s POE port.
2. Connect an Ethernet cable from your LAN to the adapter’s
LAN port.
3. Connect the Power Cord to the adapter’s power port.
Connect the other end of the Power Cord to a power outlet.
Mounting the PoE Adapter (Optional)
1. Remove the PoE Mounting Bracket from the adapter, place
the bracket at the desired location, and mark the two holes.
2. Pre-drill the holes if necessary, and secure the bracket
using two fasteners (not included).
3. Align the adapter’s slots with the tabs of the PoE Mounting
Bracket, and then slide the adapterdown.

Software Installation
Download and install the latest version of the UniFi Controller
software. Launch it and follow the on-screen instructions. The
software and step-by-step instructions in the User Guide are
available at: www.ubnt.com/download/unifi
After you have installed the software and run the UniFi
Installation Wizard, a login screen will appear for the UniFi
Controller management interface. Enter the Admin Name and
Password that you created and click Log In..
You can manage your wireless network and view network
statistics using the UniFi Controller management interface.
For information on configuring and using the UniFi Controller
software, refer to the User Guide.
Mobile App Installation
Ubiquiti Networks also offers the UniFi mobile app, which
is available from the App Store (iOS) or Google Play™Store
(Android). You can use it to provision a UniFi AP for basic
functionality without configuring a UniFi Controller. It also
allows seamless provisioning of APs for remote controllers
(controllers not on the same Layer 2 network) and easy access
to local controllers and those monitored on unifi.ubnt.com
