PCIe 4.0 x16 AIOM Slot
The motherboard features one Advanced I/O Module (AIOM) PCIe 4.0 x16 slot, which can
connect additional LAN ports, VPU, storage devices, etc. to the motherboard. Visit the
Supermicro website for all available module options. Power must be unplugged prior to
removing or installing an AIOM module card.
PCIe 4.0 x8 SlimSAS Connectors for NVMe
There are six SlimSAS connectors located at NVMe0 – NVMe5 to support six PCIe 4.0
x8 NVMe connections. These connectors provide high-speed and low-latency connections
via direct PCIe interfaces from the CPU to NVMe solid state drives (SSD). By simplifying
driver/software requirements, this greatly increases SSD data-throughput performance and
significantly reduces PCIe latency.
Power Supply SMBus I2C Header
The Power System Management Bus connector at JPI2C1 monitors the power supply, fan,
and system temperatures.
Trusted Platform Module (TPM) 2.0
A Trusted Platform Module (TPM) 2.0 header is located at JTPM1 to provide TPM 2.0 support.
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:
