SCALANCE X-400

Power is supplied by the end device. The C-PLUG retains all data permanently when the
power is turned off.
If an empty C-PLUG (factory settings or deleted with the Clean function) is inserted, all the
configuration data of the IE Switch X-400 is saved to it automatically when the device starts
up. Changes to the configuration during operation without operator intervention are saved on
the C-PLUG if this is in the "ACCEPTED" status.
Figure 3-32 C-PLUG
A device with an "ACCEPTED" C-PLUG inserted uses the configuration data of the C-PLUG
automatically when it starts up. Acceptance is possible only when the data was written by a
compatible device type.
This allows a basic device to be replaced quickly and simply. The C-PLUG is taken from the
failed component and inserted in the replacement. The first time it is started up, the
replacement device has the same configuration as the failed device except for the MAC
address set by the vendor.
Switch X-400 is replaced, the configuration with media modules and when using a
-3E also the settings of the DIL switches on the CPU module and the
optional configuration of extender modules must be adopted.
