Unit Identifier Switches
Two Unit Identifier (UID) Switches and two LED
Indicators are located on the motherboard. The
Front Panel UID Switch is located at pin 16 on JF2.
The Rear UID Switch is located at SW1 next to the
InfiniBand Connector. The Front Panel UID LED is
located at pin 17 of JF2, and the Rear UID LED is
located at LE2. When the user presses a UID switch
on the front panel or on the back panel, 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
identification of a system unit that may be in need of
service. See the table on the right for pin definitions.
Note
: UID LED is supported by the physical
switch or the BMC. When it is controlled by
the physical switch, it will stay solid. When it
is controlled by the BMC, it will blink.
