Chapter 2: System Processor Board Description
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 processor board, where server management
softwareprocessesthe signal. The system can be programmedtorespondtoanintrusion
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 preventkeyboard or mouse input and to preventuse ofthe 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
