Description
2.6 C-PLUG and KEY-PLUG
License information on the KEY-PLUG
In addition to the configuration, the KEY-PLUG also contains a license that allows the use of
the iFeatures.
PLUG with preset function (PRESET-PLUG)
With PRESET-PLUG it is possible to install the same configuration and the firmware
belonging to it on several devices.
Note
Using configurations with DHCP
Create a PRESET-PLUG only from device configurations that use DHCP. Otherwise
disruptions will occur in network operation due to multiple identical IP addresses.
You assign fixed IP addresses extra following the basic installation.
In a PLUG that was configured as a PRESET-PLUG, the device configuration, user
accounts, certificates and the firmware are stored.
Note
Restore factory defaults and restart with a PRESET PLUG inserted
If you reset a device to the factory defaults, when the device restarts an inserted PRESET
PLUG is formatted and the PRESET PLUG functionality is lost. You then need to create a
new PRESET PLUG.
We recommend that you remove the PRESET PLUG before you reset the device to the
factory settings.
For more detailed information on creating and using a PRESET PLUG refer to the section
Upkeep and maintenance (Page 421).
