Special Features; System Health Monitoring - Supermicro X11DPU-Z+ User Manual

1.3 Special Features

This section describes the health monitoring features of the X11DPU-Z+ motherboard. The
motherboard has an onboard ASpeed AST2500 Baseboard Management Controller (BMC)
that supports system health monitoring.
Recovery from AC Power Loss
The Basic I/O System (BIOS) provides a setting that determines how the system will respond
when AC power is lost and then restored to the system. You can choose for the system to
remain powered off (in which case you must press the power switch to turn it back on), or
for it to automatically return to the power-on state. See the Advanced BIOS Setup section
for this setting. The default setting is Last State.

1.4 System Health Monitoring

This section describes the health monitoring features of the X11DPU-Z+. The motherboard
has an onboard Baseboard Management Controller (BMC) chip that supports system health
monitoring. Once a voltage becomes unstable, a warning is given or an error message is
sent to the screen. The user can adjust the voltage thresholds to define the sensitivity of the
voltage monitor.
Onboard Voltage Monitors
The onboard voltage monitor will continuously scan crucial voltage levels. Once a voltage
becomes unstable, it will give a warning or send an error message to the screen. The user
can adjust the voltage thresholds to define the sensitivity of the voltage monitor. Real time
readings of these voltage levels are all displayed in BIOS.
Fan Status Monitor with Firmware Control
The system health monitor embedded in the BMC chip can check the RPM status of the
cooling fans. The CPU and chassis fans are controlled via lPMI.
Environmental Temperature Control
System Health sensors in the BMC monitor the temperatures and voltage settings of onboard
processors and the system in real time via the IPMI interface. Whenever the temperature of
the CPU or the system exceeds a user-defined threshold, system/CPU cooling fans will be
turned on to prevent the CPU or the system from overheating.
Note: To avoid possible system overheating, please be sure to provide adequate air-
flow to your system.
