next to the I-SATA ports on the mother-
board. Additionally, two 3-SGPIO ports
are also located next to JUSB 8/9. These
headers are used to communicate with
the enclosure management chip in the
system. See the table on the right for pin

DOM PWR Connector
The Disk-On-Module (DOM) power con-
nector, located at JSD1, provides 5V
(Gen1/Gen) power to a solid state DOM
storage device connected to one of the
SATA ports. See the table on the right for
