Information on the operating status and data transfer of the SCALANCE W-788-xPRO/RR or W74x-
1PRO/RR
There are several LEDs on the front of the SCALANCE W788-xPRO/RR or W74x-1PRO/RR
that provide information its operating status:
Note
If the LED for the WLAN interface is not green when the device starts up, although it is
activated, the interface is not ready for operation (interface not initialized).
The main reason for this is usually that during commissioning of a SCALANCE W788-
xPRO/RR or W74x-1PRO/RR 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.
