Desktop Board Features

Setting a user password restricts who can boot the computer. The password prompt is displayed before the computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If both passwords are set, you can enter either password to boot the computer.

Hardware Management

The hardware management features of Desktop Board DX48BT2 enable the board to be compatible with the Wired for Management (WfM) specification. The board has several hardware management features including the following:

Fan speed monitoring and control

Thermal and voltage monitoring

Chassis intrusion detection

Hardware Monitoring and Fan Speed Control

The features of the hardware monitoring and fan speed control include:

Monitoring of power supply voltages to detect levels above and below acceptable values

Intel® Precision Cooling Technology fan speed control, delivering acoustically- optimized thermal management

A thermal sensor in the processor

Thermally monitored closed-loop fan control, for all onboard fans, that can adjust fan speed or switch the fans off as needed

Intel® Precision Cooling Technology

Intel Precision Cooling Technology automatically adjust processor fan speed based on the processor temperature and adjusts chassis fan speeds based on the internal system temperature.

Chassis Intrusion

The board supports a chassis security feature that detects if the chassis cover has been removed. The security feature uses a mechanical switch on the chassis that can be connected to the chassis intrusion header on the Desktop Board. See Figure 27 for the location of the chassis intrusion header.
