Chapter 4: Motherboard Connections
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.

M.2 Connection
The system supports two M.2 solid state drives. M.2 replaces mini PCI-E and mSATA. It
allows for a greater variety of card sizes, increased functionality, and spatial efficiency. The
M.2 sockets support 3.0 x4 (32 Gb/s) card in 2260, 2280, and 22110 form factors.
Note:
If using an M.2 device with a lower thermal tolerance, a heat sink should be installed
on the top of the M.2 device and the device should be set to "boot up device" (refer to BIOS
chapter).
Onboard Power LED Header
An onboard Power LED header is located at JLED1. This Power LED header is connected to
the Front Control Panel located at JF1 to indicate the status of system power. See the table
below for pin definitions.
