4 Determine whether the Access Point is powered using a Power Injector system,
combining data and power to the Access Point’s GE1/PoE port, or is powered from a
conventional power adapter providing power only to the Access Point’s DC-48V
connector.
Precautions
Before installing an Access Point:
Verify the intended deployment location is not prone to moisture or dust.
Verify the environment has a continuous temperature range between 0° C to 40° C.
Access Point Placement
For optimal performance, install the Access Point away from transformers, heavy-duty
motors, fluorescent lights, microwave ovens, refrigerators and other industrial equipment.
Signal loss can occur when metal, concrete, walls or floors block transmission. Install the
Access Point in an open area or add Access Points as needed to improve coverage.
Antenna coverage is analogous to lighting. Users might find an area lit from far away to be
not bright enough. An area lit sharply might minimize coverage and create dark areas.
Uniform antenna placement in an area (like even placement of a light bulb) provides even,
efficient coverage.
