4.2 Headers

Fan Headers
There are four 4-pin fan headers on the motherboard. Although pins 1-3 of the fan headers
are backward compatible with the traditional 3-pin fans, we recommend you use 4-pin
fans to take advantage of the fan speed control via Pulse Width Modulation through the
thermal management. This allows the fan speeds to be automatically adjusted based on the
motherboard temperature.
Chassis Intrusion
A Chassis Intrusion header is located at JL1 on the motherboard. Attach the appropriate cable
from the chassis to inform you of a chassis intrusion when the chassis is opened. Refer to
the table below for pin definitions.
TPM/Port 80 Header
A Trusted Platform Module (TPM)/Port 80 header is located at JTPM1 to provide TPM support
and Port 80 connection. Use this header to enhance system performance and data security.
Refer to the table below for pin definitions. Please go to the following link for more information
on the TPM: http://www.supermicro.com/manuals/other/TPM.pdf.
