3.5 Hardware Management Subsystem
The hardware management features enable the Intel Server Board S875WP1-E to be
compatible with the Wired for Management (WfM) specification 2.0. The server board complies
with DMI specification 2.0 and has several hardware management features, including the
following:
4 Fan
monitoring
5
Thermal and voltage monitoring
•
Chassis intrusion detection
3.5.1
Hardware Monitoring and Fan Control ASIC
The features of the hardware monitoring and fan control ASIC (Standard Microsystems
SMSC EMC6D101 or equivalent) include:
6
Internal ambient temperature sensor
7
Two remote thermal diode sensors for direct monitoring of processor temperature and
ambient temperature sensing
8
Power supply monitoring of five voltages (+5 V, +12 V, +3.3 V Standby, +1.5 V, and
+VCCP) to detect levels above or below acceptable values
9
Thermally monitored closed-loop fan control, for four fans, that can adjust the fan speed
or switch the fans on or off as needed
•
SMBus interface
