Headers

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 Thermal Management (via Hardware Monitoring) in the BIOS. When using Thermal
Management setting, please use all 3-pin fans or 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.
SATA Ports
The H11DSi / H11DSi-NT has eight (8) available SATA 3.0 ports (CPU1-SATA0~3, CPU2-
SATA0~3) on two iPASS connectors that are supported by CPU1 and CPU2. These use an
iPASS breakout cable to support 4 ports per connector. There are also two (2) SATA ports
(P2-SATA0, P2-SATA1) that are supported by CPU2 and also provides integrated DOM (Disc
On Module) power.
