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 R1 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.
