Updating the Encryption Key
You can update the encryption key. Applying the new encryption key takes the same amount of time as
that for starting encryption. Updates are possible when the machine is working normally.
• The machine cannot be used while the encryption key is being updated.
• The encryption key is required for recovery if the machine malfunctions. Be sure to store the
encryption key safely for retrieving backup data.
• When the encryption key is updated, encryption is performed using the new key. After completing
the procedure on the machine's control panel, turn off the main power and restart the machine to
enable the new settings. Restarting can be slow when there is data to be carried over to the hard
disk.
