DOM Power Connector
A power connector for SATA DOM
(Disk On Module) devices is located at
JSD1. Connect an appropriate cable
here to provide external power for 3rd
party SATA DOM devices
Note: When using
Supermicro SuperDOMs,
no external power cabling is
required, as they draw power
directly from the yellow SATA
connectors
