Handling static-sensitive devices Attention: Static electricity can damage electronic devices, including your server. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them. To reduce the possibility of electrostatic discharge, observe the following precautions: v Limit your movement. Movement can cause static electricity to build up around you. v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed circuitry. v Do not leave the device where others can handle and damage it. v While the device is still in its static-protective package, touch it to an unpainted metal part of the server for at least 2 seconds. This drains static electricity from the package and from your body. v Remove the device from its package and install it directly into the server without setting down the device. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device on your server cover or on a metal surface. v Take additional care when handling devices during cold weather. Heating reduces indoor humidity and increases static electricity. Server power features When the server is connected to an ac power source but is not turned on, the operating system does not run, and all core logic is shut down; however, the server can respond to remote requests to turn on the server. The power-on LED flashes to indicate that the server is connected to an ac power source but is not turned on (standby mode). Turning on the server Notes: 1. Turn on all external devices, such as the monitor, before turning on the server. 2. The power-on LED on the front of the server is lit when the server is on and while it is powering-up. 3. You can install a circular disk over the power-control button to prevent accidental manual power-off. Approximately 20 seconds after the server is connected to ac power, the power-control button becomes active, and you can turn on the server and start the operating system by pressing the power-control button. The server can also be turned on in any of the following ways: v If a power failure occurs while the server is turned on, the server will restart automatically when power is restored. v If an optional Remote Supervisor Adapter II is installed in the server, the server can be turned on from the Remote Supervisor Adapter II user interface. v When you plug in your server for the first time, the Wake on LAN feature can turn on the server. If your server was previously turned on, it must be properly turned off for the Wake on LAN feature to turn on the server. 34 IBM xSeries 225 Types 8649: Hardware Maintenance Manual and Troubleshooting Guide

Handling
static-sensitive
devices
Attention:
Static
electricity
can
damage
electronic
devices,
including
your
server.
To
avoid
damage,
keep
static-sensitive
devices
in
their
static-protective
packages
until
you
are
ready
to
install
them.
To
reduce
the
possibility
of
electrostatic
discharge,
observe
the
following
precautions:
v
Limit
your
movement.
Movement
can
cause
static
electricity
to
build
up
around
you.
v
Handle
the
device
carefully,
holding
it
by
its
edges
or
its
frame.
v
Do
not
touch
solder
joints,
pins,
or
exposed
circuitry.
v
Do
not
leave
the
device
where
others
can
handle
and
damage
it.
v
While
the
device
is
still
in
its
static-protective
package,
touch
it
to
an
unpainted
metal
part
of
the
server
for
at
least
2
seconds.
This
drains
static
electricity
from
the
package
and
from
your
body.
v
Remove
the
device
from
its
package
and
install
it
directly
into
the
server
without
setting
down
the
device.
If
it
is
necessary
to
set
down
the
device,
put
it
back
into
its
static-protective
package.
Do
not
place
the
device
on
your
server
cover
or
on
a
metal
surface.
v
Take
additional
care
when
handling
devices
during
cold
weather.
Heating
reduces
indoor
humidity
and
increases
static
electricity.
Server
power
features
When
the
server
is
connected
to
an
ac
power
source
but
is
not
turned
on,
the
operating
system
does
not
run,
and
all
core
logic
is
shut
down;
however,
the
server
can
respond
to
remote
requests
to
turn
on
the
server.
The
power-on
LED
flashes
to
indicate
that
the
server
is
connected
to
an
ac
power
source
but
is
not
turned
on
(standby
mode).
Turning
on
the
server
Notes:
1.
Turn
on
all
external
devices,
such
as
the
monitor,
before
turning
on
the
server.
2.
The
power-on
LED
on
the
front
of
the
server
is
lit
when
the
server
is
on
and
while
it
is
powering-up.
3.
You
can
install
a
circular
disk
over
the
power-control
button
to
prevent
accidental
manual
power-off.
Approximately
20
seconds
after
the
server
is
connected
to
ac
power,
the
power-control
button
becomes
active,
and
you
can
turn
on
the
server
and
start
the
operating
system
by
pressing
the
power-control
button.
The
server
can
also
be
turned
on
in
any
of
the
following
ways:
v
If
a
power
failure
occurs
while
the
server
is
turned
on,
the
server
will
restart
automatically
when
power
is
restored.
v
If
an
optional
Remote
Supervisor
Adapter
II
is
installed
in
the
server,
the
server
can
be
turned
on
from
the
Remote
Supervisor
Adapter
II
user
interface.
v
When
you
plug
in
your
server
for
the
first
time,
the
Wake
on
LAN
feature
can
turn
on
the
server.
If
your
server
was
previously
turned
on,
it
must
be
properly
turned
off
for
the
Wake
on
LAN
feature
to
turn
on
the
server.
