C-PLUG and KEY-PLUG

The PLUG is a removable medium and is used to transfer the configuration of the old device to
the new device when a device is replaced.
The PLUG is available in the following variants:
● C-PLUG: The exchangeable storage medium only saves the configuration data of the
device.
● KEY-PLUG: In addition to the configuration data, the exchangeable storage medium
contains a license with which specific functions can be enabled, e.g. SINEMA RC.
How it works
NOTICE
Do not remove or insert the PLUG during operation.
A PLUG may only be removed or inserted when the device is turned off.
The device checks whether or not a PLUG is present at one second intervals. If it is detected
that the PLUG was removed, there is a restart.
If a valid KEY-PLUG was inserted in the device, the device changes to a defined error state
following the restart.
The device supports the following modes of operation:
● Without PLUG
The device saves the configuration data in the internal memory. This mode is active when
no PLUG is inserted.
● With PLUG
If an unwritten PLUG (factory status or deleted with Clean function) is used, the local
configuration already existing on the device is automatically stored on the inserted PLUG.
If the PLUG contains a license, additional functions are also enabled.
A device with a written and accepted PLUG ("ACCEPTED" status) uses the configuration
data of the PLUG automatically when it starts up. Acceptance is possible only when the data
was written by a compatible device type.
One exception to this can be the IP configuration if it is set using DHCP and the DHCP server
has not been reconfigured accordingly. Reconfiguration is necessary if you use functions
based on MAC addresses.
The configuration stored on the PLUG is displayed over the user interfaces.
If changes are made to the configuration, the device stores the configuration directly on the
PLUG, if this is in the "ACCEPTED" status. The internal memory is neither read nor written.
Response to errors
Inserting a PLUG that does not contain the configuration of a compatible device type,
accidentally removing the PLUG/KEY-PLUG or general malfunctions of the PLUG are signaled
by the diagnostics mechanisms of the device (LEDs, Web-Based Management (WBM), SNMP,
