Setting Password Protection for the User Interface
When you log on to the DSU/CSU for the Þrst time, set the superuser and the user
password parameters (case-sensitive) in Miscellaneous Management ConÞguration on
page 3-40.
Default value is an empty text string. No password is required to log on for the Þrst
time. If you do not set a password for either parameter, any user can access the
DSU/CSU.
You can set both password parameters or only the superuser password. If you set only
superuser password, the DSU/CSU uses the same password for both the user and
superuser.
With the superuser password you can set or change the passwords.
Logging On and Off the DSU/CSU
The conditions for logging on differ when the DSU/CSU terminal interface is free or
when another user is currently connected.
Use one of two methods to log on to the DSU/CSU:
¥ From a terminal (directly or through a modem) to the Comm Port
¥ From a remote terminal through a Telnet connection
Systems with blank IDs are always logged on and cannot be logged off until you assign
a unit ID to that DSU/CSU.
The Unit ID
To log on to a DSU/CSU, you need the case sensitive unit ID of that DSU/CSU.
To display the unit ID of the DSU/CSU, press Ctrl-x Þve times.
If the ID does not appear, the DSU/CSU has a bad Comm Port conÞguration or
connection.
