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).

Fault LED
If the LED is lit red, a SCALANCE X-200RNA (HSR) has detected an error/fault.
At the same time, the signaling contact opens assuming that the response of the signaling
contact has not been configured differently.
The LED signals that the SCALANCE X-200RNA (HSR) can adopt the following statuses:
Device type SCALANCE
LED lit red
LED lit yellow
LED not lit
X204RNA (HSR)
1, 2, 3, 4, 5, 6

1. Link down event on a monitored port.
2. Failure of one of the two redundant power supplies.
3. C-PLUG error.
4. Device startup, the LED is lit for approx. 20 seconds.
5. Internal error.
6. A redundancy error has been detected (unexpected frames via HSR1, HSR2, P1/A or P2/B
ports).
7. Redundancy warning (incorrect LAN ID at P1/A or P2/B)
8. No problem has been detected by the SCALANCE X-200RNA (HSR).
