Environmental Temperature Control
The thermal control sensor monitors the real-time CPU temperature. It will
turn on a back-up fan whenever the CPU temperature exceeds a user-
defined threshold. The overheat circuitry runs independently from the CPU.
It can continue to monitor for overheat conditions even if the CPU is in sleep
mode. Once it detects that the CPU temperature is too high, it will automati-
cally turn on the back-up fan to prevent any overheat damage to the CPU.
The onboard chassis thermal circuitry can monitor the overall system tem-
perature and alert users when the chassis temperature is too high.
CPU Fan Auto-Off in Sleep Mode
The CPU fan will turn on when the power is on. It can be turned off when
the CPU is in sleep mode. When the CPU is in sleep mode it does not run at
full power, and therefore generates less heat. For power saving purposes,
the user has the option to shut down the CPU fan at such times.
CPU Overheat Alarm, LED and Control
This feature is available when the user enables the CPU overheat warning
function in the BIOS. The overheat alarm will activate when the CPU tem-
perature exceeds a temperature defined by the user. When the overheat
alarm is activated both the overheat fan and the LED are triggered.
Chassis Intrusion Detection
The chassis intrusion circuitry can detect unauthorized intrusion to the sys-
tem. The chassis intrusion connector is located on JL1. Attach a micro-
switch to JL1. When the micro-switch is closed, it means that the chassis
has been opened. The circuitry will then alert the user with a warning
message when the system is turned on. This feature is available when the
user is running Intel's LANDesk Client Manager, and SUPERMICRO's Super
Doctor.
System Resource Alert
This feature is available when used with Intel's LANDesk Client Manager
(optional). The user can be notified of certain system events. For example,
if the system is running low on virtual memory, the hard drive space is not
enough to save the data, you are then alerted of the potential problems.
