LED Display on a Hardware Unit
The hardware units have LEDs which provide a speedy overview of the
operating state of the hardware unit. On the wall version, the LEDs are
aligned in a row with 6 LEDs next to one another; the rack version has 2 rows
of 3 consecutive LEDs.
LEDs 1 to 6: Wall version and rack version
The following table shows the general assignment of the LEDs:
The LED 1 lights up green if the power supply unit is correctly supplying all
required operating voltages. If the LED 1 is not lit, this indicates that there is
either no power supply or power supply is defective.
The LED 2 lights up yellow if the file system of the hardware unit is accessed.
You should not disconnect the power supply if this LED is lit or is flashing.
LED 3 to LED 6 are controlled by the operating software. These LEDs are
flashing during a software update. Depending on the operating mode (call
server or gateway) these LEDs have different functions.
