LAN1/2 (Ethernet Ports)
Two Ethernet ports (designated LAN1
and LAN2) are located beside the VGA
port on the I/O backplane. These ports
accept RJ45 type cables.
SGPIO
The two headers labeled SGPIO1
and SGPIO2 are for SGPIO (Se-
rial General Purpose Input/Output).
SGPIO provides a bus between the
SATA controller and the SATA drive
backplane to provide SATA enclosure
management functions. Connect the
appropriate cables from the backplane
to the SGPIO1 and SGPIO2 headers
to utilize SATA management functions
on your system.
Alarm Reset (JAR)
The system will notify you in the event
of a power supply failure. This feature
assumes that Supermicro redundant
power supply units are installed in the
chassis. Connect a microswitch to the
JAR header to disable the power supply
fail alarm.
