I-SGPIO 1/2 Headers
Two SGPIO (Serial-Link General Purpose
Input/Output) headers are provided on the
serverboard. These headers are used to
communicate with the enclosure manage-
ment chip in the system. I-SGPIO 1/2 is
for the I-SATA 0~5 ports See the table on
the right for pin definitions.
Ethernet Ports
Two Gigabit Ethernet ports (LAN1, LAN2) are located on the rear I/O panel. In ad-
dition, a dedicated IPMI LAN port is located above the USB 12/13 ports on the I/O
panel. All these ports accept RJ45 type cables. Please refer to the LED Indicator
Section for LAN LED information.
Two additional 10Gb Ethernet ports are also provided, these are designated as
LAN3 and LAN4.

Unit Identifier Switch/UID LED
Indicator
The rear UID switch is located next to
the LAN ports on the rear I/O panel. The
front UID switch is located on pin 13 of
the Front Panel Control header (JF1).
The rear UID LED (UID) is located next
to the UID switch and the front UID LED
is located on pin 7 on JF1. When you
press the UID switch, the UID LED will
turn on. Press the UID switch again to
