Area of application and function of the C-PLUG
Area of application
The C-PLUG (configuration plug) that ships with the product is an exchangeable memory
medium for storing the configuration data of the device. The device can also be operated
without a C-PLUG.
This allows fast and uncomplicated replacement of a device. The C-PLUG is taken from the
previous device and inserted in the new device. The first time it is started up, the
replacement device has the same configuration as the previous device except for the MAC
address set by the vendor.
