4.2 Headers and Connectors
Fan Headers
This motherboard has eight fan headers (FAN1-8). FAN1-FAN7 are regular 4-pin fan headers,
and FAN8 is a vertical one. These are 4-pin fan headers, although pins 1-3 are backward
compatible with traditional 3-pin fans. Four-pin fans allow fan speeds to be controlled by
Thermal Management in
fans or all 4-pin fans.
TPM Header
The JTPM1 header is used to connect a Trusted Platform Module (TPM)/Port 80, which
is available from Supermicro. A TPM/Port 80 connector is a security device that supports
encryption and authentication in hard drives. It allows the motherboard to deny access if the
TPM associated with the hard drive is not installed in the system.
RAID Key Header
A RAID Key header is located at JRK1 on the motherboard. It supports VMD used in creating
optional advanced NVMe RAID configurations.
IPMI.
