feature enabled when you receive it.
Setup Password options in system setup:
l
Enabled — does not allow assignment of setup passwords; users must enter a setup password to make changes to system setup
l
Not Enabled — allows assignment of setup passwords; password feature is enabled but no password is assigned
Assigning a Setup Password

2. Highlight Setup Password and press the left- or right-arrow key.
The system prompts you to enter and verify the password. If a character is illegal for password use, the system emits a beep.

After you verify the password, the Setup Password setting changes to Enabled . The next time you attempt to enter system setup, the
system prompts you for the setup password.
NOTE: If you have assigned a setup password, the system accepts your setup password as an
alternate system password.
NOTE: You can use Password Status in conjunction with System Password and Setup
Password to further protect your system from unauthorized changes.
