2.2 Precautions
Before installing an AP-7602, verify the following:
• You are using the correctly rated power solution for the AP-7602 (either the power
injector or the external power supply)
• Do not to install the AP-7602 in wet or dusty areas.
• Verify the environment has a continuous temperature range between 32° F to 104°
(0-40°C).
• This product is intended for indoor use only.
2.3 Placing the AP-7602
For optimal performance, install the AP-7602 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 AP-7602 in an
open area or add Wireless Wallplates 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.
To maximize the radio coverage area, Zebra recommends conducting a site survey to define
and document radio interference obstacles before installing the AP-7602.
2.4 Power Injector System
An AP-7602 can receive power via an Ethernet cable connected to the GE1/POE (LAN) port.
The AP-7602 can receive power from either a standard 802.3af PSE connected to GE1, or a
12VDC power supply.
When users purchase a WLAN solution, they often need to place units in obscure locations.
In the past, a dedicated power source was required for each AP-7602 in addition to the
Ethernet infrastructure. This often required an electrical contractor to install power drops at
each AP-7602 location. The Power Injector merges power and Ethernet into one cable,
