Super X11DSN-TS/X11DSN-TSq User's Manual

1.3 Special Features

This section describes the health monitoring features of the motherboard. The motherboard
has an onboard ASPEED 2500 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 motherboard. The motherboard
has an onboard Baseboard Management Controller (BMC) chip (AST2500) that supports
system health monitoring.
Onboard Voltage Monitoring
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 IPMI WebGUI and
IPMIView. Real time readings of these voltage levels are all displayed in IPMI.
Fan Status Monitor with Firmware Control
The system health monitor embedded in the BMC chip (AST2500) can check the RPM status
of the cooling fans. The CPU and chassis fan speeds are controlled thermal management
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 pre-defined or a manufacturer-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.
