Power-ON
Display
When
the
library
powers
ON
or
resets,
it
goes
through
several
internally
controlled
processes
that
allow
it
to
get
initialized
and
running.
These
processes
are
called
Power-On-Self-Test
(POST).
During
the
POST
the
Operator
Control
Panel
will
display
information
that
may
be
meaningless
until
POST
is
complete.
When
the
POST
is
finished,
the
library
will
display
the
current
library
status
in
the
Home
Screen.
While
the
library
is
going
through
its
power
up
cycle
the
user
can
monitor
the
state
of
the
library
via
the
OCP;
however,
the
user
will
not
be
able
to
make
any
configuration
changes
until
the
unit
has
completed
its
initialization
routine.
Attempts
to
make
changes
will
be
ignored.
Note
about
the
Front
Panel
LEDs
All
LEDs
are
updated
during
power
ON
and
reset
sequences.
Upon
power
ON
or
software
reset,
the
library
will
illuminate
all
LEDs
as
soon
as
POST
allows.
When
initialization
starts,
all
LEDs
will
be
extinguished
and
the
Ready/Activity
LED
will
flash
at
a
rate
of
approximately
one
second
per
cycle.
When
the
mechanical
initialization
is
complete,
the
Ready/Activity
LED
will
stop
flashing
and
be
constantly
illuminated.
If
a
library
failure
occurs,
the
Ready/Activity
LED
will
turn
OFF
and
the
Error
LED
will
illuminate.
The
Operator
Control
Panel
will
also
display
an
appropriate
error
code
to
help
identify
the
failure.
The
following
are
additional
operational
details
of
LEDs:
v
The
Ready/Activity
LED
will
be
lit
any
time
the
unit
is
powered
ON
and
functional.
The
Ready/Activity
LED
will
blink
whenever
there
is
library
or
drive
activity.
This
LED
will
also
blink
when
the
unit
is
OFFLINE.
