v Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist watches. v Remove items from your shirt pocket (such as pens or pencils) that could fall into the server as you lean over it. v Avoid dropping any metallic objects, such as paper clips, hair pins, or screws, into the server. System reliability considerations To help ensure proper cooling and system reliability, make sure that: v Each of the drive bays either has a drive, or a filler panel and electromagnetic compatibility (EMC) shield installed. v There is space around the server to allow the server cooling system to work properly. Leave about 127 mm (5 in.) of space around the front and rear of the server. v Cables for optional adapters are routed according to the instructions that are provided with the adapters. v A failed fan is replaced within 1 hour. Handling static-sensitive devices Attention: Static electricity can damage electronic devices and your system. To avoid damage, keep static-sensitive devices in their static-protective bag 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 printed circuitry. v Do not leave the device where others can handle and possibly damage the device. v While the device is still in its anti-static package, touch it to an unpainted metal part of the system unit for at least two seconds. (This drains static electricity from the package and from your body.) v Remove the device from its package and install it directly into your system unit without setting it down. If it is necessary to set the device down, place it on its static-protective package. (If your device is an adapter, place it component side up.) Do not place the device on your system unit cover or on a metal table. Chapter 5. Installing options 45

watches.
v
Remove
items
from

System
reliability
considerations
To
help
ensure
proper
cooling
and
system
reliability,
make
sure
that:
v
Each
of
the
drive
bays
either
has
a
drive,
or
a
filler
panel
and
electromagnetic
compatibility
(EMC)
shield
installed.
v
There
is
space
around
the
server
to
allow
the
server
cooling
system
to
work
properly.
Leave
about
127
mm
(5
in.)
of
space
around
the
front
and
rear
of
the
server.
v
Cables
for
optional
adapters
are
routed
according
to
the
instructions
that
are
provided
with
the
adapters.
v
A
failed
fan
is
replaced
within
1
hour.
Handling
static-sensitive
devices
Attention:
Static
electricity
can
damage
electronic
devices
and
your
system.
To
avoid
damage,
keep
static-sensitive
devices
in
their
static-protective
bag
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
printed
circuitry.
v
Do
not
leave
the
device
where
others
can
handle
and
possibly
damage
the
device.
v
While
the
device
is
still
in
its
anti-static
package,
touch
it
to
an
unpainted
metal
part
of
the
system
unit
for
at
least
two
seconds.
(This
drains
static
electricity
from
the
package
and
from
your
body.)
v
Remove
the
device
from
its
package
and
install
it
directly
into
your
system
unit
without
setting
it
down.
If
it
is
necessary
to
set
the
device
down,
place
it
on
its
static-protective
package.
(If
your
device
is
an
adapter,
place
it
component
side
up.)
Do
not
place
the
device
on
your
system
unit
cover
or
on
a
metal
table.
