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.
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.
I-SATA Ports (I-SATA0~I-SATA7), H12SSL-i/C/CT Only
The H12SSL-i/C/CT/NT has eight available SATA 3.0 ports (SATA0~7) on the motherboard.
I-SATA0~I-SATA7 are standard SATA 3.0 ports. SATA0~7 (JNVME0) and SATA8~15 (JNVME1)
support SATA 3.0 drives, requiring a break-out cable.
