Ethernet Ports
Two Gigabit Ethernet ports (LAN1,
LAN2) are located on the I/O backplane.
In addition, a dedicated IPMI LAN port
is located above the USB 0/1 ports on
the backplane to provide KVM support
for IPMI 2.0. All these ports accept
RJ45 type cables.

Unit Identier Switch
A Unit Identifier (UID) Switch and
two LED Indicators are located on
the serverboard. The UID Switch is
located next to the LAN ports on the
backplane. The Rear UID LED (LED3)
is located next to the UID Switch. The
Front Panel UID LED is located at
Pins 7/8 of the Front Control Panel at
JF1. Connect a cable to Pin 8 on JF1
for Front Panel UID LED indication.
When you press the UID switch, both
Rear UID LED and Front Panel UID
LED Indicators will be turned on. Press
the UID switch again to turn off both
LED Indicators. These UID Indicators
provide easy identication of a system
unit that may be in need of service.
Note: UID can also be triggered via
IPMI on the serverboard. For more
information on IPMI, please refer to
the IPMI User's Guide posted on our
