System-board LEDs The following illustration shows the LEDs on the system board. You might have to refer to this illustration when you are solving problems with the server. Note: The server does not contain a light path diagnostics panel. mini-BMC heartbeat LED Microprocessor fan error LED Standby power LED System fan error LED VRD power fault LED System power LED DASD fan error LED DIMM 1 error LED DIMM 2 error LED DIMM 3 error LED DIMM 4 error LED Use the system-board LEDs to diagnose system errors. An error LED is lit to indicate a problem with a specific component. After a problem is corrected, its LED will not be lit the next time that the server is restarted; if the problem remains, the LED will be lit again.

System-board
LEDs
The
following
illustration
shows
the
LEDs
on
the
system
board.
You
might
have
to
refer
to
this
illustration
when
you
are
solving
problems
with
the
server.
Note:
The
server
does
not
contain
a
light
path
diagnostics
panel.

Use
the
system-board
LEDs
to
diagnose
system
errors.
An
error
LED
is
lit
to
indicate
a
problem
with
a
specific
component.
After
a
problem
is
corrected,
its
LED
will
not
be
lit
the
next
time
that
the
server
is
restarted;
if
the
problem
remains,
the
LED
will
be
lit
again.
