1-16 System Overview
Keyboard and Mouse
The PS/2 compatible keyboard and mouse connectors are mounted in a single-stacked
housing with the mouse connector over the keyboard. External to the system, they
appear as two connectors.
The user can plug in the keyboard and mouse to either connector before powering up
the system. BIOS detects these and configures the keyboard controller accordingly.
The keyboard controller is functionally compatible with the 8042A microcontroller.
The system can be locked automatically if no keyboard or mouse activity occurs for a
predefined length of time, if specified through the SSU (see security options in
“Security Add-in). Once the inactivity (lockout) timer has expired, the keyboard and
mouse do not respond until the previously stored password is entered.
Remote Power-On (Wake On LAN) Function
The remote power-on (Wake On LAN) function turns on the system power by way of
the network. If the system power is set to Off, it can be turned on remotely by sending a
specific packet from the main computer to the remote system.
System Security
To help prevent unauthorized entry or use of the system, the system includes a full
lockable front cover and internal software locks via the BIOS setup utility and system
setup utility (SSU).
Security with Mechanical Lock
The front cover of the server contains a mechanical lock to prevent access to the front
of the computer chassis.
Software Locks
The BIOS Setup Utility and System Setup Utility (SSU) provide a number of security
features to prevent unauthorized or accidental access to the system, as follows.
Security with BIOS Setup:
!
Set server administrative and user passwords.
!
Set secure mode to prevent keyboard or mouse input and to prevent use of the front
panel controls.
