Fan Headers
The X10SL7-F has fi ve fan headers (Fan1
- Fan4 and FanA). These are all 4-pin fan
headers, however pins 1-3 are backward
compatible with traditional 3-pin fans. Fan
speed is controlled via IPMI based on the
system temperature. Refer to the table on
the right for pin defi nitions.
Note: Please use all 3-pin fans or all 4-pin
fans. Do not mix 3-pin fans and 4-pin fans
on the same board.
Chassis Intrusion
A Chassis Intrusion header is located at
JL1 on the motherboard. Attach the ap-
propriate cable from the chassis to inform
you of a chassis intrusion when the chas-
sis is opened.

Trusted Platform Module Header
This header is used to connect a Trusted
Platform Module (TPM), available sepa-
rately from a third-party vendor. A TPM is
a security device that allows encryption
and authentication of hard drives, disal-
lowing access if the TPM associated with
it is not installed in the system. See the
table on the right for pin defi nitions.
