Managing Your System

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.

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
