4.2 Headers and Connectors

Chassis Intrusion
A Chassis Intrusion header is located at JL1 on the motherboard. Attach the appropriate cable
from the chassis to inform you of a chassis intrusion when the chassis is opened. Refer to
the table below for pin definitions.
Fan Headers
There are seven 4-pin fan headers (FAN1–FAN5, FANA, FANB) on the motherboard. All
these 4-pin fan headers are backwards compatible with the traditional 3-pin fans. However,
fan speed control is available for 4-pin fans only by Thermal Management via the IPMI 2.0
interface. Refer to the table below for pin definitions.
M.2 Slot
The X13SCL-F motherboard has one M.2 slot. M.2 was formerly known as Next Generation
Form Factor (NGFF) and serves to replace mini PCIe. M.2 allows for a variety of card sizes,
increased functionality, and spatial efficiency. The M.2 socket on the motherboard supports
PCIe 4.0 x4 slots or SSD cards in a 2280 / 22110 form factor.
