6.4.3.4 Shut-down mode
If, for maintenance purposes, the SMB Controller should be disconnected from the power supply, it must be
shut down in a controlled manner. This means, the applications need some time to save their data and to
close. When the shut-down mode is reached, the SMB Controller will remain in this mode for 1.5 minutes
before it starts up again automatically. During this period, the SMB Controller can be disconnected from the
power supply without concerns.
Note:
Never disconnect the SMB Controller from the power supply to trigger a restart. This can result in data
losses and prevent a restart.
