wireless adapter’s documentation.
4 Hardware Installation
4.1 Attaching Antennas
Note: When facing the front of the ZyAIR, the right antenna (main antenna) transmits and receives, the
left antenna only receives.
Follow the steps below to connect the supplied antennas.
4.2 Hardware Mounting Installation
In general, the best location for the access point is at the center of your intended wireless coverage area. For
better performance, mount the ZyAIR high up free of obstructions.
This is the final wizard screen. You may
return to the MAIN MENU and continue
to configure your ZyAIR.
1Locate the antenna connectors on
the sides of your ZyAIR.
2Screw the antennas clockwise onto
the antenna connectors. The
antennas should be perpendicular
to the ground and parallel to each
other.
Note: Make sure the antennas are
securely screwed onto the
antenna connectors.

Free-standing
Place your ZyAIR on a flat, level surface (on a desk or shelf) that is strong enough to support the weight of the
ZyAIR with connection cables.
Wall-mounted
Follow the steps to attach your ZyAIR to a wall.
1Locate a high position on the wall that is free of obstructions.
2Connect two screws (not included) in the wall 60mm apart. You can use the diagram at the end of this
guide to help you mark the screw holes correctly. Use screws with 6mm ~ 8mm (0.24" ~ 0.31") wide heads.
Do not screw the screws all the way in to the wall. Leave a small gap between the head of the screw and
the wall. The gap must be big enough for the screw heads to slide into the screw slots and the connection
cables to run down the back of the ZyAIR.
Note: Make sure the screws are securely fixed to the wall and strong enough to hold the weight of the
ZyAIR with the connection cables.
3Adjust the cables.
Run the connection cables down the back of the ZyAIR as shown in the following figure.
OR:
Run the connection cables upward and along the edge of the ceiling.

5 Power over Ethernet (PoE)
6 Troubleshooting
4Align the holes on the back
of the ZyAIR with the screws
on the wall. Hang the ZyAIR
on the screws.
Power over Ethernet (PoE) is the
ability to provide power to your ZyAIR
via an 8-pin CAT 5 Ethernet cable,
eliminating the need for a nearby
power source.
An injector or PoE device (not
included) is also needed to supply the
Ethernet cable with power. This
feature allows increased flexibility in
the locating of your ZyAIR.
Problem Corrective Action
The PWR LED is off. Make sure you are using the correct power adaptor and the power adaptor is plugged
into an appropriate power supply.
Unplug the power adaptor and plug it in again. If the error persists, you may have a
hardware problem. In this case, you should contact your vendor.
