CPU Overheat LED and Thermal Fan Control
This feature is available when the user enables the CPU overheat warning
function in the BIOS. The overheat sensor is triggered when the CPU tem-
perature exceeds the temperature configured by the user. When the overheat
sensor is triggered, both the overheat LED and thermal controlled fan are
activated.
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. 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.
Hardware BIOS Virus Protection
The system BIOS is protected by hardware so that no virus can infect the
BIOS area. The user can only change the BIOS content through the flash
utility provided by SUPERMICRO. This feature can prevent viruses from
infecting the BIOS area and loss of valuable data.
Switching Voltage Regulator for the CPU Core
The switching voltage regulator for the CPU core can support up to 20A
current, with auto-sensing voltage ID ranging from 1.8v to 3.5v. This will allow
the regulator to run cooler and make the system more stable.
