System Security To help prevent unauthorized entry or use of the system, the system includes a three-position key lock/switch to permit selected access to drive bays (position is communicated to BMC). The system also includes server management software that monitors the chassis intrusion switch. 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 baseboard, where server management software processes the signal. The system can be programmed to respond to an intrusion by powering down or by locking the keyboard, for example. Software Locks via the SSU or BIOS Setup The SSU provides a number of security features to prevent unauthorized or accidental access to the system. Once the security measures are enabled, access to the system is allowed only after the user enters the correct password(s). For example, the SSU allows you to: • Enable the keyboard lockout timer so the server requires a password to reactivate the keyboard and mouse after a specified time-out period of 1 to 120 minutes • Set and enable administrator and user passwords • Set secure mode to prevent keyboard or mouse input and to prevent use of the front panel reset and power switches • Activate a hot-key combination to enter secure mode quickly • Disable writing to the diskette drive when secure mode is set Using Passwords If you set and enable a user password but not an administrator password, enter the user password to boot the system and run the SSU. If you set and enable both a user and an administrator password: • Enter either one to boot the server and enable the keyboard and mouse • Enter the administrator password to access the SSU or BIOS Setup to change the system configuration Secure Mode Configure and enable the secure boot mode by using the SSU. When secure mode is in effect, you: • Can boot the system and the OS will run, but you must enter the user password to use the keyboard or mouse • Cannot turn off system power or reset the system from the front panel switches Secure mode has no effect on functions enabled via the Server Manager Module or power control via the real-time clock (RTC). Taking the system out of secure mode does not change the state of system power. That is, if you press and release the power switch while secure mode is in effect, the system will not power off when secure mode is later removed. However, if the front panel power switch remains depressed when secure mode is removed, the system will power off. 28
