12) IDE/SCSI Activity LED (2-pin IDELED) Also in Panel Connectors
This connector supplies power to the cabinet's activity LED. Read and write
activity by devices connected to the Primary/Secondary IDE and SCSI connectors
cause the LED to light up.
CUR-DLSR IDE Activity LED
13) CPU and Chassis Fan Connectors (3-pin CPU_FAN1/2, CHA_FAN1/2)
These connectors support cooling fans of 860mA (10.3 Watts) or less. Orient
the fans so that the heat sink fins allow airflow to go across the onboard heat
sink(s) instead of the expansion slots. Depending on the fan manufacturer, the
wiring and plug may be different. The red wire should be positive, while the
black should be ground. Connect the fan's plug to the board taking into
consideration the polarity of the connector.
NOTE: The "Rotation" signal is to be used only by a specially designed fan with
rotation signal. The Rotations per Minute (RPM) can be monitored using Intel LDSM
Utility (provided with certain models).
WARNING!
The CPU and/or motherboard will overheat if there is no airflow
across the CPU and onboard heatsinks. Damage may occur to the motherboard
and/or the CPU fan if these pins are incorrectly used. These are not jumpers,
do not place jumper caps over these pins.
