Fan Headers
There are eight 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
Fan Mode in the BMC. When using Fan Mode setting, please use all 4-pin fans.
Chassis Intrusion
A Chassis Intrusion header is located at JL1 on the motherboard. Attach the appropriate cable
from the chassis to the header to inform you when the chassis is opened.
Disk-On-Module Power Connector
The Disk-On-Module (DOM) power connectors at JSD1 and JSD2 provide 5V power to a
solid-state DOM storage device connected to one of the SATA ports. See the table below for
pin definitions.
