Change admin password
Besides supporting the use of console management interface through the connection of null modem,
the system also supports the SSH online connection for the setup. When using a null modem to connect
to the system console, there is no need to enter that administrator's password to access the console
management interface. When connecting the system via SSH, however, the username and password
will be needed.
The username and the default password is "admin" by default, which is similar to the web management
interface. The administrator's password can be changed. Even if the password is forgotten and the
management interface cannot be accessed from the web or the remote end of the SSH, the null modem
can still be used to connect the console management interface where the administrator's password can
then be reset.
Caution: Although it does not require a username and password for the connection via the serial port, the same
management interface can be accessed via SSH. Therefore, it is recommended that you immediately change the
DSA-6100 Admin username and password after logging into the system for the first time.
