System
Power-On
Methods
This
section
discusses
the
following
system
power-on
methods:
v
Hardware
Management
Console
(HMC)
Using
the
HMC
is
the
preferred
method
of
powering
on
a
managed
system.
For
details
on
using
the
HMC
to
power
up
a
system,
see
the
IBM
Hardware
Management
Console
for
pSeries
Installation
and
Operations
Guide
.
v
Power-on
Switch
v
Service
Processor
Menus
Privileged
users
can
power
on
the
system
by
selecting
the
System
Control
Power
Menu
option
from
the
main
menu
and
then
selecting
the
Power-on
System
option
from
the
System
Power
Control
Menu.
General
users
should
select
Power-on
System
on
the
General
User
Menu.
v
Remote
Power-on
via
Ring-Indicate
Signal
The
server
automatically
powers
on
when
it
detects
a
″
ring
indicate
″
signal
from
a
modem
attached
to
serial
port
1
(S1)
or
serial
port
2
(S2).
A
remote
user
can
call
the
server
to
activate
ring
detection
by
the
modem.
Listen
for
a
few
more
rings
than
the
threshold
number
for
starting
the
system.
The
system
powers
on
without
answering
the
call.
v
Unattended
start
mode
-
refer
to
Enable/Disable
Unattended
Start
Mode
on
page
The
service
processor
can
be
enabled
to
recover
from
the
loss
of
ac
power
(see
Enable/Disable
Unattended
Power-On
Mode
in
the
SYSTEM
POWER
CONTROL
MENU).
When
ac
power
is
restored,
the
system
returns
to
the
power
state
at
the
time
ac
loss
occurred.
For
example,
if
the
system
was
powered
on
when
ac
loss
occurred,
it
reboots/restarts
when
power
is
restored.
If
the
system
was
powered
off
when
ac
loss
occurred,
it
remains
off
when
power
is
restored.
v
Timed
power-on
-
refer
to
the
shutdown
-t
command
on
servers
using
AIX.
Working
in
conjunction
with
AIX,
the
Service
Processor
in
your
server
can
operate
a
timer,
much
like
the
wake-up
timer
on
your
clock
radio.
You
can
set
the
timer
so
that
your
server
powers
on
at
a
certain
time
after
shutting
down.
The
timer
is
battery-operated,
so
power
interruptions
that
occur
while
the
server
is
off
do
not
affect
its
accuracy.
Refer
to
the
AIX
shutdown
-t
command
for
details
on
setting
the
timer.
Note:
If
an
ac
power
loss
(exceeding
the
hold-up
time
of
any
optional
IBFs)
is
in
progress
when
the
timed
power-on
attempt
occurs,
the
server
cannot
power
on
when
ac
power
is
restored.
v
Follow-up
to
a
Failed
Boot
Attempt
The
service
processor
initiates
a
power-on
sequence
if
a
failed
boot
attempt
is
detected
(due
to
a
hardware
or
software
failure).
v
Fast
or
Slow
Boot
(IPL)
Using
the
service
processor
menus,
you
can
select
the
IPL
type,
mode,
and
speed
of
your
system.
Attention:
Selecting
fast
IPL
results
in
several
diagnostic
tests
being
skipped
and
a
shorter
memory
test
being
run.
