The Standby Power LED is located
at LED2 on the motherboard. When
LED2 is on, it means that the AC

power supply hard switch is on,
indicating that power is flowing
through the power supply and into
the motherboard. The system may or
may not be running.

A rear UID LED indicator (LE1) is
located next to the I/O backplane. This
UID Indicator assists in identification
of a system. It may be triggered by
the UID switch or IPMI.
