TPM Header/Port 80 Connector
The JTPM1 header is used to connect a Trusted Platform Module (TPM), which is available from
a third-party vendor. A TPM is a security device that supports encryption and authentication in
hard drives. It enables the motherboard to deny access if the TPM associated with the hard
drive is not installed in the system.

NVM Express Connections
Two NVM Express ports are located on the serverboard (one for each processor). These
ports provide high-speed, low-latency PCI-Exp. 3.0 x4 connections directly from the CPU to
NVMe Solid State (SSD) drives. This greatly increases SSD data-throughput performance
and signicantly reduces PCI-E latency by simplifying driver/software requirements resulted
from direct PCI-E interface from the CPU to the NVMe SSD drives.
System Management Bus (SMB) Header
System Management Bus headers for additional slave devices or sensors is located at JSMB
and JSMB1.
PCI-E M.2 Connector
The PCI-E M.2 connector is for devices such as memory cards, wireless adapters, etc.
These devices must conform to the PCIE M.2 specications (fromerly known as NGFF). This
particular PCIe M.2 supports M-Key (PCIe x2) storage card only.
