Page 34 highlights

To reduce the possibility of damage from electrostatic discharge, observe the following precautions: v Limit your movement. Movement can cause static electricity to build up around you. v The use of a grounding system is recommended. For example, wear an electrostatic-discharge wrist strap, if one is available. Always use an electrostatic-discharge wrist strap or other grounding system when you work inside the server with the power on. 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 on the outside 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 the server cover or on a metal surface. v Take additional care when you handle devices during cold weather. Heating reduces indoor humidity and increases static electricity. Removing the cover Important: Before you install optional hardware devices, make sure that the server is working correctly. Start the server, and make sure that the operating system starts, if an operating system is installed, or that a 19990305 error code is displayed, indicating that an operating system was not found but the server is otherwise working correctly. If the server is not working correctly, see the Problem Determination and Service Guide for diagnostic information. To remove the cover, complete the following steps: 1. Read the safety information that begins on page v and "Installation guidelines" on page 20. 2. If you are installing or replacing a non-hot-swap component, turn off the server and all attached peripheral devices. Disconnect all power cords; then, disconnect all external signal cables from the server. 3. Slide the server out of the rack until the slide rails lock into place. 22 IBM System x3755 Type 8877: User's Guide

To
reduce
the
possibility
of
damage
from
electrostatic
discharge,
observe
the
following
precautions:
v
Limit
your
movement.
Movement
can
cause
static
electricity
to
build
up
around
you.
v
The
use
of
a
grounding
system
is
recommended.
For
example,
wear
an
electrostatic-discharge
wrist
strap,
if
one
is
available.
Always
use
an
electrostatic-discharge
wrist
strap
or
other
grounding
system
when
you
work
inside
the
server
with
the
power
on.
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
on
the
outside
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
the
server
cover
or
on
a
metal
surface.
v
Take
additional
care
when
you
handle
devices
during
cold
weather.
Heating
reduces
indoor
humidity
and
increases
static
electricity.
Removing
the
cover
Important:
Before
you
install
optional
hardware
devices,
make
sure
that
the
server
is
working
correctly.
Start
the
server,
and
make
sure
that
the
operating
system
starts,
if
an
operating
system
is
installed,
or
that
a
19990305
error
code
is
displayed,
indicating
that
an
operating
system
was
not
found
but
the
server
is
otherwise
working
correctly.
If
the
server
is
not
working
correctly,
see
the
Problem
Determination
and
Service
Guide
for
diagnostic
information.
To
remove
the
cover,
complete
the
following
steps:
1.
Read
the
safety
information
that
begins
on
page
v
and
“Installation
guidelines”
on
page
20.
2.
If
you
are
installing
or
replacing
a
non-hot-swap
component,
turn
off
the
server
and
all
attached
peripheral
devices.
Disconnect
all
power
cords;
then,
disconnect
all
external
signal
cables
from
the
server.
3.
