Clear Password. By default, the
DXM Controller does not require a password to load a configuration file. If a password is
defined, the DXM Controller requires that you enter the password before uploading a configuration file. To change the
password, you must already know the current password. If you do not know the current password, clear the password
from the DXM Controller.
CAUTION: Clearing the password erases the current configuration and any program files, log files, or
history files currently on the
DXM Controller.
Follow these steps to clear the password requirement from your DXM Controller.
