Fault indicator (yellow/red LED)

Fault indicator (yellow/red LED)
If the LED is lit red, a SCALANCE X-200RNA 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 can adopt the following statuses:
Device type SCALANCE
X204RNA
X204RNA EEC
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 was detected.
7. No problem has been detected by the SCALANCE X-200RNA.

Power display

Power display
The LEDs signal the following statuses of the SCALANCE X-200RNA.
The status of the power supply is indicated by a green LED:
Device type SCALANCE
X204RNA
X204RNA EEC
1. Both L power supplies are connected (redundant supply).
2. One L power supply is connected (non-redundant supply).
3. Power supply L1 and L2 are not connected or supply voltages are <14 V.
