Description

4.2 LED display

SCALANCE W786 outdoor access point

16 Operating Instructions, 06/2013, A5E02280428-08

Note

If the LED for the WLAN port is not

green when the device starts up, although it is activated,

the port is not ready for operation (interface not initialized).

The main reason for this is usually that during commissioning of the SCALANCE

W78x

products, a waiting time of up to 15 minutes can

occur when the ambient temperature is

below zero. The device is ready for operation at the specified ambient temperature as soon

as the LED for the WLAN interface is lit green.

Note

Primary user (radar) on all enabled channels

If the device detects a primary user on all enabled channels (for example radio waves of a

radar station), the LEDs F

and

flash. No data traffic is then possible for the next 30

minutes. After this time, the device runs the scan again and checks whether

a primary user

still exists. If no primary user is detected, data traffic is possible again.

The wait time of 30 minutes is necessary due to legal requirements and cannot be shortened

even by resetting the device.
