System Overview 1-27
AC Link Mode
The AC link mode allows the system to monitor its AC input power so that when the
AC input power is lost and then restored the system will return itself to one of three pre-
selected settings, listed as follows:
!
Power On
!
Last State (Factory Default Setting)
!
Stay Off.
The AC link mode settings can be changed by running the BIOS Setup Utility (F2).
Refer to Chapter 3 "Configuring Your System."
Remote Power-On (Wake On LAN) Function
The remote power-on function turns on the system power by way of a network or
modem. 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.
Note:
The standard default value of the remote power-on
function is “Disabled”. To enable it, the Wake On LAN item in the
System Hardware menu of the BIOS Setup Utility described in
Chapter 3 “BIOS Setup Configuration Settings” must be changed to
“Enabled.”
System Security
To help prevent unauthorized entry or use of the system, the system includes a full
lockable front cover and Server Management software that monitors the system.
Security with Mechanical Locks and Monitoring
The front cover of the tower-based system contains a mechanical lock to prevent access
to the front of the computer chassis.
The computer chassis includes an interlock switch for the processor cover, which
controls power shutdown. When the interlock switch is opened, power to the system is
turned off for safety reasons.
Security with the rack-mount system is identical to the tower-based system stated
above, except that the mechanical locks are on the front and rear doors of the rack
cabinet.
