4 Control elements
4.1 status LEDs
The S5/S7-TimeServer has multiple different status LEDs on the front
side of the device.
The first green LED is located on the bottom left corner next to the power
connector and lights when the device is powered.
For a simple diagnostic of the RJ45 interfaces every connector has its
own green LED. This LED lights when a link state is detected and blinks
on data transfer.
Furthermore there are some more LEDs on the bottom right corner for a
diagnostic of the mobile connection. The five green LEDs below the bars
are showing up the signal strength. This means the more LEDs are light
up the better the signal is. The LED directly below the mobile symbol is a
multi color LED and gives more information about the current general
mobile connection:
