IMPORTANT NOTE: FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should
be installed and operated with a minimum distance of 70 centimeters (27.5 inches) between the radiator and your body. This
transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Wireless 5 GHz Band Statements:
As the Access Point can operate in the 5150-5250 MHz frequency band it is limited by the FCC to indoor use only so as to
reduce the potential for harmful interference to co-channel Mobile Satellite systems.
High power radars are allocated as primary users (meaning they have priority) of the 5250-5350 MHz and 5650-5850 MHz
bands. These radars could cause interference and /or damage to the access point when used in Canada.
Wireless 4.9 GHz Band Statement:
Installation and operartion requires an approved license from the FCC.

Symptom Action
Power LED is Off • AC power adapter may be disconnected. Check connections between
the access point, the power adapter, and the wall outlet.
• PoE power to the access point may be disabled at the connected
switch port. Check the switch configuration to be sure that PoE power
is enabled for the switch and specified port. Also check that the switch
has not exceeded its power budget and turned off the port power.
Power LED is Amber The access point has detected a system error. Reboot the access point
to try and clear the condition.
If the condition does not clear, contact your local dealer for assistance.
Ethernet/Link LED is Off • Verify that the access point and attached device are powered on.
• Be sure the cable is plugged into both the access point and
corresponding device.
• Verify that the proper cable type is used and its length does not exceed
specified limits.
• Check the cable connections for possible defects. Replace the
defective cable if necessary.

Operating Range
Note: The operating range distances listed in the following tables are for typical environments
only. Operating ranges can vary considerably depending on factors such as local interference and
barrier composition. It is recommended to do a site survey to determine the maximum ranges for
specific access point locations in your environment.
