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.
