to
the
condition
in
which
the
server
is
connected
to
an

source
but
the
server
operating
system
is
not
running
and
all
core
logic
is
shut
down
except
for
the
service
processor.
In
Standby
mode,
the
server
can
respond
to
service
processor
requests,
such
as
a
remote
request
to
turn
on
the
server.
When
the
server
is
in
Standby
mode,
the
power-on
LED
on
the
front
of
the
server
flashes
(when
the
server
is
running,
the
power-on
LED
stays
on
and
does
not
flash).

This
starts
an
orderly
shutdown

the
operating
system,
if
this
feature

by
your
operating
system.
v
If
the
server
is
connected
to
an
ASM
interconnect
network
that
contains
at
least
one
system
with
an
optional
Remote
Supervisor
Adapter
installed,
the
server
can
be
placed
in
Standby
mode
from
the
Remote
Supervisor
Adapter
user
interface.
v
If
an
optional
Remote
Supervisor
Adapter
is
installed
in
the
server,
the
server
can
be
placed
in
Standby
mode
from
the
Remote
Supervisor
Adapter
user
interface.
Attention:
You
must
disconnect
all
the
server
power
cords
from
the
electrical
outlets
to
remove
all
power
from
the
server.
Complete
the
following
steps
to
put
the
server
into
Standby
mode:
1.
See
the
operating
system
documentation
for
the
proper
procedure
to
shut
down
the
operating
system.

for
more
than
4
seconds
to
cause

it
into
Standby
mode.
You
can
use
this
feature
if
the
operating
system
stops
functioning.
The
ISMP
can
put
the
server
in
Standby
mode
as
an
automatic
response
to
a
critical
system
failure.
You
can
also
put
the
server
into
Standby
mode
remotely
by
means
of
an
optional
Remote
Supervisor
Adapter
or
through
connection
to
an
ASM
interconnect
network.
