4.2 Headers and Connectors
Onboard Fan Headers (FAN1~FAN5, FANA, FANB)
There are seven fan headers on the motherboard. These are 4-pin fan headers; pins 1-3
are backward compatible with traditional 3-pin fans. The onboard fan speeds are controlled
by Thermal Management (via Hardware Monitoring) in the BMC. When using Thermal
Management setting, please use all 4-pin fans.

PCIe M.2 Connector (J23)
The PCIe M.2 (J2) connector is for devices such as memory cards, wireless adapters, etc.
These devices must conform to the PCIe M.2 specifications (formerly known as NGFF). This
particular PCIe M.2 supports M-Key (PCIe x4) storage card.
NCSI Header (JNCSI1)
The NCSI (Network Controller Sideband Interface) header is located at JNCSI1. This header
is an interface used to connect the BMC (Baseboard Management Controller) to a set of
Network Interface Controllers to enable out-of-band remote manageability.
