Unit Identifier Switch/LED Indicators
A Unit Identifier (UID) switch and two LED indicators are provided on the
motherboard. The rear UID switch is located between the VGA connector and the
COM port on the I/O backpanel. The front UID LED is located at pin 7 of JF1 and
the rear UID LED is located at LED1. When the user presses the UID switch on
the back panel, both front and rear UID LEDs will be turned on. Press the UID
switch again to turn off both LED indicators. These UID Indicators provide easy
identification of a system unit that may be in need of service. See the table on the
right for pin definitions.
Note
: the UID LED is supported by the physical switch or the BMC. When controlled
by the physical switch, it will be solid. When it is controlled by the BMC, it will blink.
IPMI LAN Port
An dedicated IPMI LAN port is located next to the USB2/3 ports on the backplane.
This Ethernet port accepts an RJ45 type cable. Please refer to the LED Indicator
section for LAN LED information.
Serial Ports
A COM (serial) port is located on the I/O backpanel on the motherboard. This
connection provides serial connection support.
