Powering
Off
the
System
With
an
HMC
Attached
and
Linux
Installed
The
HMC
user
interface
provides
a
power-off
function
to
turn
off
the
power
to
the
system.
If
the
system
is
logically
partitioned,
Linux
may
be
stopped
individually
in
each
partition
to
make
repairs.
If
the
system
power
must
be
turned
off,
all
of
the
logical
partitions
must
be
stopped.
Linux
does
not
provide
hot-swap
procedures
for
adapter
and
device
removal
and
installation.
You
must
shutdown
all
partitions
and
the
system
power
must
be
turned
off
to
service
an
adapter
or
device.
Individual
power
components
and
fans
may
be
serviced
with
power
on
for
power
systems
equipped
with
redundant
power
and
cooling.
Check
removal
and
installation
procedures
before
servicing
this
system.
As
the
system
goes
off,
the
power
LED
on
the
operator
panel
starts
blinking
at
a
fast
rate.
B0FF
appears
in
the
primary
operator
panel
display.
When
the
power-off
sequence
is
complete,
the
system
goes
into
standby
mode,
as
evidenced
by
the
following:
v
OK
displays
in
the
operator
panel
display.
v
The
operator-panel
LED
will
start
blinking
at
a
slow
rate.
v
The
processor
subsystem
power
LED
will
start
blinking
at
a
slow
rate.
To
completely
remove
power
from
a
subsystem
in
the
frame,
use
one
of
the
following
procedures
based
on
the
presence
or
absence
of
the
High
Performance
Switch
(7045-SW4):
v
If
a
High
Performance
Switch
(7045-SW4)
is
not
installed
in
the
processor
subsystem
frame,
input
power
to
a
subsystem
must
be
removed
by
turning
off
the
UEPO
switch
and
turning
off
the
circuit
breakers
on
all
optional
IBF
subsystems
(if
provided).
v
If
a
High
Performance
Switch
(7045-SW4)
is
installed
in
the
processor
subsystem
frame,
input
power
to
a
subsystem
may
be
selectively
removed
from
the
processor
subsystem,
an
I/O
subsystem,
or
switch
subsystem
using
the
HMC
as
described
below:
The
HMC
user
interface
provides
a
power-off
function
to
turn
off
the
power
to
an
individual
subsystem.
For
information
about
shutting
down
and
powering
off
an
individual
subsystem,
see

Basic
System
Management
Tasks
″
,
located
in
the
IBM
Hardware
Management
Console
for
pSeries
Installation
and
Operations
Guide
.
Attention:
If
a
High
Performance
Switch
is
present
in
the
frame,
using
the
UEPO
switch
to
remove
power
from
a
subsystem
being
serviced
will
remove
power
from
ALL
of
the
subsystems
that
are
receiving
power
from
the
frame.
This
may
result
in
unintended
outages
and
extended
down
time.
If
you
are
servicing
an
individual
I/O
subsystem,
refer
to
the
information
about
deactivating
a
system’s
I/O
drawers,
found
in
″
Basic
System
Management
Tasks,
located
in
the
IBM
Hardware
Management
Console
for
pSeries
Installation
and
Operations
Guide
to
remove
350
V
power
from
both
of
the
I/O
subsystem
DCA
UPIC
cable
connections.
Before
deactivating,
ensure
that
you
shut
down
the
operating
system
on
all
partitions
that
are
using
the
resources
of
the
I/O
subsystem
being
serviced.
After
deactivating
the
I/O
subsystem,
both
the
Power-In
LED
and
the
Power-Out
LED
on
the
front
of
the
I/O
subsystem
DCAs
should
be
off.
If
not,
call
service
support.
If
you
are
servicing
the
processor
subsystem,
refer
to
the
information
about
deactivating
a
managed
system’s
service
processor,
found
in
″
Basic
System
Management
Tasks
″
,
located
in
the

Guide
to
remove
350
V
power
from
the
processor
subsystem

cable
connections.
Before
deactivating,
ensure
that
you
shut
down
the
operating
system
on
all
partitions
that
are
running
on
the
processor
subsystem
being
serviced.
After
deactivating
the
processor
subsystem,
both
the
Power-In
LED
and
the
Power-Out
LED
on
the
front
of
the
processor
subsystem
DCA
should
be
off.
If
not,
do
not
continue.
Call
service
support.
v
If
a
High
Performance
Switch
(7045-SW4)
is
not
installed
in
the
processor
subsystem
frame,
input
power
must
be
removed
by
turning
off
the

switch,
turning
off

breakers
on
all
optional
IBF
subsystems
(if
provided),
and
then
disconnecting
both
power
cords
from
the
customer’s
receptacle.
If
the
system
is
operating
in
a
full
system
partition
under
Linux,
typing
the
shutdown
now
-h
command
causes
the
system
to
shut
down
and
power
off.
The
