Fan Headers
The PDSMi-LN4 has six fan connections
(Fan1 to Fan6). Fan6 is designated as the
CPU Cooling Fan. (
Note
: all these fans are
4-pin fans. However, Pins 1-3 of the fan
headers are backward compatible with the
traditional 3-pin fans.) See the table on the
right for pin defi nitions. (*The onboard fan
speeds are controlled by Thermal Manage-
ment in the BIOS Hardware Monitoring
Setting
.
When using Thermal Manage-
ment setting, please use all 3-pin fans or
all 4-pin fans on the motherboard. Please
do not use 3-pin fans and 4-pin fans on
the same board. The default setting is
"Disabled" which will allow the onboard
fans to run at the full speed.)

Power Fault
Connect a cable from your power supply to
the Power Fault header (PW3) to provide
warning of power supply failure. This warn-
ing signal is passed through the PWR_LED
pin to indicate of a power failure on the
chassis. See the table on the right for pin
defi nitions.
Note:
This feature is only available when using
redundant Supermicro power supplies.
