Description
2.5 PLUG
The device supports the following modes of operation:
• Without C-PLUG/KEY-PLUG
The device stores the configuration in internal memory.
This mode is active if no C-PLUG/KEY-PLUG is inserted.
• With unwritten C-PLUG/KEY-PLUG
If an unwritten C-PLUG/KEY-PLUG (factory status or deleted with Clean function) is
used, the local configuration already existing on the device is automatically stored on
the inserted C-PLUG/KEY-PLUG during startup.
This mode is active as soon as an unwritten C-PLUG/KEY-PLUG is inserted.
• With written C-PLUG/KEY-PLUG
A device with a written and accepted C-PLUG/KEY-PLUG ("ACCEPTED" status) uses
the configuration data of the PLUG automatically when it starts up. The requirement
for acceptance is that the data was written by a compatible device type.
If there is configuration data in the internal memory of the device, this is overwritten.
This mode is active as soon as a written C-PLUG/KEY-PLUG is inserted.
Response to errors
Inserting a C-PLUG/KEY-PLUG that does not contain the configuration of a compatible
device type, accidentally removing the C-PLUG/KEY-PLUG or general malfunctions of
the C-PLUG/KEY-PLUG are signaled by the diagnostics mechanisms of the device:
• Fault LED
• Web Based Management (WBM)
• SNMP
• Command Line Interface (CLI)
The user then has the choice of either removing the C-PLUG/KEY-PLUG again or
selecting the option to reformat the C-PLUG/KEY-PLUG.
