Device description
5.9 LEDs
3. Following startup, the correct link status is indicated by the port LEDs after approximately 5
seconds.
4. The SCALANCE X-200RNA (HSR) 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.
5.9.2.5
Mode LED (SCALANCE X204RNA EEC (PRP/HSR))
The SCALANCE X204RNA EEC (PRP/HSR) has the labeling of both devices on its housing, in other
words, that of the SCALANCE X204RNA EEC (PRP) and the SCALANCE X204RNA EEC (HSR).
Depending on how you configure the SCALANCE X204RNA EEC (PRP/HSR), the labeling is valid
as described in the sections above.
The exception is the mode LED (third LED from the top):
• When the LED is lit, the SCALANCE X204RNA EEC (PRP/HSR) is in HSR mode. This means that
the right-hand labeling of the LED displays applies. The device behaves like a SCALANCE
X204RNA EEC (HSR).
• When the LED is not lit, the SCALANCE X204RNA EEC (PRP/HSR) is in PRP mode. This means
that the left-hand labeling of the LED displays applies. The device behaves like a SCALANCE
X204RNA EEC (PRP).
