Non-port
side
of
the
DR550
SAN
switch
The
non-port
side
of
the
switch
is
used
solely
for
air
flow
and
for
serial
number
labels.
The
three
built-in
fans
are
located
on
this
side
of
the
switch.
These
fans
cannot
be
removed
or

Interpreting
LED
activity
System
activity
and
status
can
be
determined
through
the
activity
of
the
LEDs
on
the
switch.
All
the
switch’s
LEDs
are
located
on
the
port
side
of
the
switch.
There
are
three
possible
LED
states:
no
light,
a
steady
light,
and
a
flashing
light.
The
steady
lights
and
flashing
lights
can
be
green
or
amber.
Sometimes
the
LEDs
flash
either
of
these
colors
during
boot,
POST,
or
other
diagnostic
tests.
This
is
normal
and
does
not
indicate
a
problem
unless
all
boot
processes
and
diagnostic
tests
are
complete,
and
the
LEDs
continue
to
indicate
a
problem
status.
