4.3.2 User Names, Passwords and Groups
You may want to change your system access passwords frequently, in order to maintain
optimum security on your network. The recommended passwords are a minimum of 6 and no
more than 12 characters in length, are not found in a dictionary, and contain both letters and
numbers. Because the system is case-sensitive for password entries, you can mix uppercase
and lowercase letters to provide more possible passwords.
The user administration function is activated by entering ‘n’ for usrNames from the CPU Main
screen, as shown in Figure 4-2 on page 4-2.
Note: The passwords MUST be at least six characters long and MUST be a combination of
characters and at least one digit!
The system supports 256 possible users. Each user is defined by the use of three entries or
fields. The fields are editable by a user who has Administrator or Superuser access. Following
is a brief description to the user fields:
Action Function
Save Saves changes to settings.
Undo Returns all settings to the last saved state.
Refresh Updates certain time-related information fields that are not automatically
updated (i.e., performance and test data).
tcp/Ip Allows the user to configure for TCP/IP functionality.
