Do not turn off the power or overload the device while writing the image to flash-
memory. These actions will lead to a partial recording of firmware, which is equivalent to
damage to the boot partition of the device. The device will become inoperable. You may
restore the device operation only trough RS-232 by using a special COM port adapter for
connection to computer.
As from FW version 2.6.0, password encryption function was added to all device
configuration files. If you need to change a password for web or for connection to the
device via telnet or ssh when you prepare config.file or *.cfg for autoconfiguration, delete
‘encrypted’ and specify user password in /etc/config/passwd file. For example, to change
password of admin user you must replace option 'adm_password_encrypted'
'2B5141626956D541' with option 'adm_password' '*new password*'.
