Onboard Fan Headers (FAN1~FAN6)
There are six 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.
Disk-On-Module Power Connector (JSD1 & JSD2)
The Disk-On-Module (DOM) power connector at JSD1 provides 5V power to a solid-state DOM
storage device connected to one of the SATA ports. See the table below for pin definitions.
SATA (SATA16, SATA17)
The H12SSW-iNL/NTL has two available SATA 3.0 ports (SATA16 and SATA17). These are
