Notices and statements used in this book The caution and danger statements used in this book also appear in the multilingual Safety Information book provided on the IBM BladeCenter Documentation CD. Each caution and danger statement is numbered for reference to the corresponding statement in the safety book. The following notices and statements are used in the documentation: v Note: These notices provide important tips, guidance, or advice. v Important: These notices provide information or advice that might help you avoid inconvenient or problem situations. v Attention: These notices indicate possible damage to programs, devices, or data. An attention notice is placed just before the instruction or situation in which damage could occur. v Caution: These statements indicate situations that can be potentially hazardous to you. A caution statement is placed just before the description of a potentially hazardous procedure step or situation. v Danger: These statements indicate situations that can be potentially lethal or extremely hazardous to you. A danger statement is placed just before the description of a potentially lethal or extremely hazardous procedure step or situation. Power, controls, and indicators This chapter describes the power features, how to turn on and turn off the blade server, and what the controls and indicators mean. Turning on the blade server After you connect the blade server to power through the BladeCenter unit, the blade server can start in any of the following ways. Note: Unless otherwise stated, references to the BladeCenter unit also apply to the BladeCenter T unit. v You can press the power-control button on the front of the blade server (behind the control panel door) to start the server. Notes: 1. After you connect the power cords of your BladeCenter unit to the electrical outlets, wait until the power-on LED on the blade server flashes slowly before pressing the blade server power-control button. During this time, the service processor in the BladeCenter management module is initializing; therefore, the power-control button on the blade server does not respond. 2. While the blade server is starting up, the power-on LED on the front of the server is lit steady. See "Controls and LEDs" on page 8 for the power-on LED states. v If a power failure occurs, the BladeCenter unit and then the blade server can start automatically when power is restored (if the blade server is configured through the BladeCenter management module to do so). v You can turn on the blade server remotely by means of the service processor in the BladeCenter management module. 6 BladeCenter HS40 Type 8839: Hardware Maintenance Manual and Troubleshooting Guide

Power,
controls,
and
indicators
This
chapter
describes
the
power
features,
how
to
turn
on
and
turn
off
the
blade
server,
and
what
the
controls
and
indicators
mean.
Turning
on
the
blade
server
After
you
connect
the
blade
server
to
power
through
the
BladeCenter
unit,
the
blade
server
can
start
in
any
of
the
following
ways.
Note:
Unless
otherwise
stated,
references
to
the
BladeCenter
unit
also
apply
to
the
BladeCenter
T
unit.
v
You
can
press
the
power-control
button
on
the
front
of
the
blade
server
(behind
the
control
panel
door)
to
start
the
server.
Notes:
1.
After
you
connect
the
power
cords
of
your
BladeCenter
unit
to
the
electrical
outlets,
wait
until
the
power-on
LED
on
the
blade
server
flashes
slowly
before
pressing
the
blade
server
power-control
button.
During
this
time,
the
service
processor
in
the
BladeCenter
management
module
is
initializing;
therefore,
the
power-control
button
on
the
blade
server
does
not
respond.
2.
While
the
blade
server
is
starting
up,
the
power-on
LED
on
the
front
of
the
server
is
lit
steady.
See
“Controls
and
LEDs”
on
page
8
for
the
power-on
LED
states.
v
If
a
power
failure
occurs,
the
BladeCenter
unit
and
then
the
blade
server
can
start
automatically
when
power
is
restored
(if
the
blade
server
is
configured
through
the
BladeCenter
management
module
to
do
so).
v
You
can
turn
on
the
blade
server
remotely
by
means
of
the
service
processor
in
the
BladeCenter
management
module.
