Ac Link Mode; Remote Power-On (Wake On Lan) Function; System Security; Security With Mechanical Locks And Monitoring - NEC Express5800 series User Manual

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

To help prevent unauthorized system entry or use, the bezel has a door and three-
position key lock. The bezel door provides access to the front panel buttons, the front
panel USB and serial ports, the hot-swap drive bays, and the peripheral devices. The
three lock positions are:
!
Locked—The bezel door can't be opened and the bezel can't be removed.
!
Door unlocked—The bezel door can be opened, but the bezel can't be removed.
!
Unlocked—The bezel door can be opened, and the bezel can be removed.
The server includes two chassis intrusion switches: one for the front access cover and
one for the rear access cover. When opening either access cover, the switch transmits an
alarm signal to the baseboard management controller.
Server management software processes signals received from the intrusion switches.
