8.1 Device configuration with PRESET-PLUG
Procedure
1. Start the remote configuration using Telnet (CLI) and log on with a user with the
"admin" role.
2. Switch to the global configuration mode with the command "configure terminal".
3. You change to the PLUG configuration mode with the "plug" command.
4. Create the PRESET-PLUG with the "presetplug" command.
The firmware version of the device and the current device configuration incl. user
accounts and certificates are stored on the PLUG and the PLUG is then write
protected.
5. Turn off the power to the device.
6. Remove the PRESET-PLUG.
7. Start the device either with a new PLUG inserted or with the internal configuration.
Procedure for installation with the aid of the PRESET-PLUG
1. Turn off the power to the device.
2. If it exists, remove the PLUG from the slot. You will find further information on this in
the operating instructions of your device.
3. Insert the PRESET-PLUG correctly oriented into the slot. The PRESET-PLUG is
correctly inserted when it is completely inside the device and does not jut out of the
slot.
4. Turn on the power to the device again.
If there is a different firmware version on the device to be installed compared with that
on the PRESET-PLUG, an upgrade/downgrade of the firmware is performed. You can
recognize this by the red F-LED flashing (flashing interval: 2 sec on/0.2 sec. off).
Afterwards the device is restarted and the device configuration incl. users and
certificates on the PRESET-PLUG is transferred to the device.
5. Wait until the device has fully started up.
The red F-LED is off.
6. Turn off the power to the device after the installation.
7. Remove the PRESET-PLUG.
8. Start the device either with a new PLUG inserted or with the internal configuration.
Note
KEY-PLUG
If you have created the PRESET-PLUG from a KEY-PLUG, for operation with this
configuration, you require an inserted KEY-PLUG.
IN this case before recommissioning the device you need to insert the relevant KEY-
PLUG.
