– If the restore procedure was not successful, the SF LED flickers red (10 Hz).
Note
If the Service selector switch is not reset or not reset in good time to "0", this results in
fault state "Service selector switch is still set to restore" (SF LED flickers red at 10 Hz).
In this case, switch the D4x5-2 off, reset the Service selector switch and switch the
D4x5-2 on again. If the restoration was otherwise successful, the D4x5-2 boots up
with the restored configuration.
Note
In the case of a CPU upgrade via USB stick the SIMOTION D4x5-2 is booted from the
USB stick. A bootable USB stick must therefore be used. Due to the rapid
developments within the market for USB sticks, it is not possible to recommend any
