Fan Headers
This serverboard has 11 system
fan headers (FAN1 ~ FAN7, FANA
~ FAND). FAN6 is for CPU1 and
FAN7 for CPU2. All these 4-pin fans
headers are backward compatible
with the traditional 3-pin fans. The fan
speeds for 4-pin fans are controlled by
Thermal Management via IPMI. See
the table on the right for pin denitions.
Internal Speaker
The Internal Speaker, located at
SP1, can be used to provide audible
indications for various beep codes.
See the table on the right for pin
