Hardware Monitoring

Intel® Server Board SE7505VB2

6.2

Fan Speed Control

The Winbond W83627HF can be used to monitor several critical hardware parameters of the

system, including power supply voltages, fan speeds, and temperatures. Fan speed control is to

use the Pulse Width Modulation (PWM) technical knowledge to control the Fan's RPM.

The following shows the temperature range vs. output voltage for controlling the speed of all

system fans.

Chassis Intrusion

The SE7505VB2 server board supports a chassis security feature that detects if the chassis

cover is removed. For the chassis intrusion circuit to function, the chassis’ power supply must

be connected to AC power. The security feature uses a mechanical switch on the chassis that

attaches to the chassis intrusion connector. When the chassis cover is removed the mechanical

switch is in the closed position.
