4. Power supply L is connected
5. Power supply L is not connected or the supply voltage is too low.

Port LED
The LEDs signal the following port statuses of the SCALANCE X-200RNA (PRP).
The status of the ports is indicated by two-color LEDs:

1. TP link exists, no data reception.
2. TP link, data received at TP port.
3. Device startup, the LED is lit for approx. 6 seconds.
4. Setting or display of the fault mask.

LED displays during startup
When the SCALANCE X-200RNA (PRP) starts up, the following LED displays light up in the order
shown:
1. Power LEDs (green) light up immediately after turning on the power.
2. Port LEDs go off, the red error LED is lit for approx. 10 seconds.
3. Following startup, the correct link status is indicated by the port LEDs after approximately 5
seconds.
4. The SCALANCE X-200RNA (PRP) is now ready for operation.
Note
SCALANCE X204RNA EEC (PRP/HSR)
If the device has not yet been configured, a device error is indicated (red fault LED lit
permanently). This means that no link can be established on the redundancy ports.
In this case, the mode LED also flashes since the operating mode is not defined.
