4.2 Headers and Connectors

NC-SI Connector
A Network-Controller Sideband Interface (NC-SI) header is located at JNCSI1 on the
motherboard. The NCSI header is used to connect a Network Interface Card (NIC) to the
motherboard so that the BMC is able to poll the temperature reading from it.
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.
Expansion Slots
The motherboard features two expansion slots (JSXB0 and JSXB1). These are both PCIe
5.0 x16 slots (JSXB0 is for a left-hand riser card and JSXB1 is for a right-hand riser card).
AIOM Slot
An Advanced I/O Module (AIOM) slot supports a networking adapter card with multiple RJ45
ports. This slot also supports NC-SI.
