Headers and Connectors
I-SATA 3/4 & M.2 Connectors
Two-SATA 3.0 connectors (I-SATA 3/4) are located on the AOM-X11OPi-LBG. These SATA
ports are supported by the Intel PCH chip and are used with Supermicro SuperDOM (Disk-
on-Module) connectors with power-pins built in. The SuperDOM connectors are backward-
compatible with regular SATA HDDs and SATA DOMs. In addition, two M.2 connectors (J1, J2)
are also located on the PCH board to provide SATA 3.0 (or PCI-E 3.0) support. All SATA ports
provide serial-link signal connections, which are faster than the connections of Parallel ATA.
Note:
Supermicro SuperDOMs are yellow SATADOM connectors with power pins built in and
do not require separate external power cables. These connectors are backward-compatible
with non-Supermicro SATADOMs that require an external power supply. For more information
on the SATA HostRAID configuration, please refer to the Intel SATA HostRAID user's guide

the UID switch, the UID LED will be turned on. Press the UID switch again to turn it off. These
UID indicator provide easy identification of a system unit that may be in need of service.
