Security Procedures
Your server is equipped with security features to help prevent theft
or unauthorized use of your server. Your User's Reference contains a
complete explanation of these features. To use or change some of
these features, you might need to remove the server cover.
Two types of system passwords are available to prevent
unauthorized access to your server. These are the administrative
and user passwords. They are described in detail in your User's
Reference. To set or change these passwords and other
security-related parameters, follow the instructions given in
Chapter 3, “Configuring Your Server” on page 39.
