NVMe VPP Bus Connector
A NVMe VPP Bus connector is located at JNVVPP1 on the motherboard. The NVMe VPP
connector provides hot plug support for the NVMe devices, which will allow the user to replace
NVMe devices without shutting down and powering off the system.
Chassis Intrusion
A Chassis Intrusion header is located at JL1. Attach the appropriate cable from the chassis
to the header to alert when the chassis is opened.
AIOM Sideband Connector (JAIOM2SB1)
A Supermicro proprietary Advanced I/O Module (AIOM) sideband connector is located at
JAIOM2SB1 on the motherboard. This connector provides the AIOM sideband signals for an
optional second AIOM IO board.
PCIe I C Header
2
A PCIe I C (SMBus) header is located at JRSI2C1. It is used for PCIe cards to allow the BMC
2
or the BIOS to read disk drive information or FRUs more effectively.
PCIe 3.0 M.2-H1/M.2-H2 Slots
Two PCIe 3.0/SATA3 Hybrid M.2 slots are located at M.2-H1 and M.2-H2 on the motherboard.
These M.2/SATA3 Hybrid slots support PCIe 3.0 x4 M.2 NVMe/SATA3 SSDs in the 2280 and
22110 form factors. To accommodate the 2280 and 22110 form factors, two M.2 mounting
holes (MH17/MH18) are provided on the motherboard. Use Mounting Hole MH17 for M.2-H2
slot support, and MH18 for M.2-H1 slot support. M.2 allows for a variety of card sizes,
increased functionality, and spatial efficiency.
MCIO NVMe Connectors
MCIO NVMe connectors, located at P1_NVME 0–3 and P2_NVME 0–3, provide eight PCIe
5.0 x8 connections on the motherboard. P1_NVME 0–3 connections are supported by CPU1,
and P2_NVME 0–3 connections supported by CPU2. NVMe VPP and NVMe SMBus signals
are included in MCIO NVMe connectors P1_NVME 1 and P2_NVME 1. Use these MCIO
connectors to support high-speed PCIe storage devices.
