Using passwords
Passwords can be set to prevent unauthorized access to the server.
Despite passwords enhance data security, they are not required. Read the following topics if you decide to 
set any passwords.
To start the Setup Utility program, complete the following steps: 
Password Types
The following types of passwords are available in the Setup Utility program:
•  Power-on password
When a power-on password is set, you are prompted to enter a valid password each time the server is 
turned on. The server cannot be used until the valid password is entered.
•  Administrator password
Setting an administrator password deters unauthorized users from changing configuration settings. If you 
are responsible for maintaining the configuration settings of several servers, you might want to set an 
administrator password. 
When an administrator password is set, you are prompted to enter a valid password each time you try to 
access the Setup Utility program. The Setup Utility program cannot be accessed until a valid password is 
entered.
If both the power-on password and administrator password are set, you can enter either password. 
However, you must use your administrator password to change any configuration settings.
•  Hard disk password
Setting a hard disk password prevents unauthorized access to the data on the internal storage drive (such 
as a hard disk drive). When a hard disk password is set, you are prompted to enter a valid password each 
time you try to access the storage drive.
