Fan Headers
The PDSM4/PDSME has fi ve chasis/sys-
tem fan headers (Fan1 to Fan5) and one
CPU Fan (CPU Fan6). (*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 Management via BIOS Hardware
Monitor in the Advanced Setting
.
Note:
Default: Disabled, When using Thermal
Management 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.)

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.
