1.3 Special Features

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

Onboard Voltage Monitors
The baseboard management controller (BMC) will monitor the voltages of the onboard chipset,
memory, and CPU. Once the voltage exceeded certain threshold values, an error message
is logged in the system event log in the BMC.
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 monitor temperatures and voltage settings of onboard processors and
the system in real time via the BMC interface. Whenever the temperature of the CPU or the
system exceeds Supermicro's pre-defined threshold, the system and CPU cooling fan speed
will increase to prevent the CPU or system from overheating.
Note: To avoid possible system overheating, please be sure to provide adequate air-
flow to your system.
