Mechanical locks and monitoring
The system includes a chassis intrusion switch. When the access cover is opened, the switch transmits an alarm signal to the system board, where server management software processes the signal.
Software locks through the BIOS Setup utility
The Security tab in the BIOS (see “About the BIOS Setup utility” on page 67) provides several security features to prevent unauthorized access to the system. Once the security measures are enabled, access to the system is allowed only after you enter the correct password(s). For example, the security features let you:
■Set and enable supervisor and user passwords.
■Set Unattended Start mode to prevent keyboard or mouse input.
■Set user BIOS setup access level (full, limited, view only, or no access).
■Set Password Check for setup only or always.
■Enable Unattended Start mode which, when enabled, allows the host system to complete the boot process without a password, yet causes the keyboard and mouse to remain locked until the user password is enabled.
Using passwords
If you set and enable a user password but not a supervisor password, enter the user password to boot the system with unlimited BIOS Setup access.
If you set and enable both a user and a supervisor password:
■Enter either one to boot the server and enable the keyboard and mouse.
■Enter the supervisor password for full access the BIOS Setup to change the system configuration.
Changing passwords

To change or delete an existing supervisor password, restart the system and press F1 to enter the BIOS Setup utility, then enter the supervisor password (not the user password) when the system asks for the password during the
