Light
path
diagnostics
The
server’s
light
path
diagnostics
feature
provides
a
path
that
can
be
followed
in
distinct
phases
to
help
identify
the
source
of
an
error.
The
lights
are
designed
to
be
followed
in
an
orderly
progression,
depending
on
the
error.
The
LEDs
are
viewed
in
the
following
order:
1.
Begin
on
the
front
panel.
2.
Proceed
to
the
light
path
diagnostics
panel.
3.
Check
the
system
service
label.
4.
Look
inside
the
server,
if
necessary.
Many
errors
are
first

of
the
system-error
light
in
the
operator
information
panel
on
the
front
of
the
server
(see
“Server
controls,
LEDs,
and
power”
on
page

If
the
system-error
light
is
lit,
one
or
more
lights
inside
the
server
might
also
be
lit
that
can
direct
you
to
the
source
of
the
error.
The
system
information
LED
lights
to
alert
you
that
there
might
be
important
information
recorded
in
the
system-error
log.
