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.

Note: For troubleshooting wireless connectivity problems, refer to the RoamAbout Wireless Access Point RBT-4102
