6. 4. 3. 9 Shutdown Mode
If, for maintenance purposes, the communication server is disconnected from the 
power supply, it must be shut down under control (see "Shutting down the com-
munication server", page 213). It then remains in Shutdown Mode for three min-
utes before it starts again automatically. During this period the communication 
server can be disconnected from power supply.
Notes:
Never disconnect the communication server from the power supply to 
trigger a restart. This can result in data losses and prevent a restart.
Combination pattern [22] is displayed in shutdown mode.

6. 4. 3. 10 Error Mode
The system switches to Error Mode if a problem or error occurs that prevents the 
system’s normal operation. This can be a hardware error or a software installation 
error.
The Error Mode is indicated by the red SYS-LED flashing very rapidly and is exited 
only once the error is remedied. In many cases this involves a system restart.
The different errors are binary coded and are indicated by the LEDs (F0...F4).
