Chassis Intrusion
A Chassis Intrusion header is located at JL1 on the motherboard. Attach the appropriate
cable from the chassis to inform you when the chassis is opened. Refer to the table below
for pin definitions.
NVMe SMBus Header
The NVMe SMBus (I C) header (JNVI2C1) provides hot-plug support via a dedicated SMBus

interface. This feature is only available for a Supermicro complete system with an SMCI-
proprietary NVMe add-on card and a proper cable installed. See the table below for pin
definitions.
PCIe 4.0 M.2 Slots
The X13DEI/X13DEI-T motherboard has two PCIe 4.0 M.2 slots. M.2 allows for a variety of
card sizes, increased functionality, and spatial efficiency. The M.2 slots on the motherboard
