1-14 System Overview
System Security
To help prevent unauthorized entry or use of the system, the system includes a full
lockable front panel and Server Management software that monitors the system
intrusion switches.

Security with Mechanical Locks and Monitoring

The front panel of the tower-based system contains a mechanical lock to prevent access
to the front of the computer chassis. In addition, each side cover contains a padlock
loop (padlock not provided) located on the rear of the chassis to prevent removal of the
side covers and access to the inside of the computer chassis
The computer chassis includes an intrusion switch for the front cover and
intrusion/interlock switches for both the left side and the right-side covers (as viewed
from the front). When any these covers are opened, the switch transmits an alarm signal
to the system board, where server management software processes the signal. The side
cover switches also operate as interlock switches. That is if only one power supply
module is installed the switches operate as intrusion switches or if two power supply
modules are installed the switches operate as inter-lock switches controlling power shut
down to the system for safety reasons.
Security with the rack-mount system is identical to the tower-based system stated
above, except that there is no front cover associated with the rack-mount system.

Software Locks via the System Setup Utility

The BIOS Setup Utility and the System Setup Utility (SSU) provide 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:
! Enable the keyboard lockout timer so that the server requires a password to
reactivate the keyboard and mouse after a specified time-out period1 to 120
minutes.
! Set and enable an administrative password.
! Set and enable a user password
! 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.
