v Have a small flat-blade screwdriver available. v You do not have to turn off the server to install or replace hot-swap fans, redundant hot-swap ac power supplies, or hot-plug Universal Serial Bus (USB) devices. However, you must turn off the server before performing any steps that involve removing or installing adapter cables or non-hot-swap optional devices or components. v Blue on a component indicates touch points, where you can grip the component to remove it from or install it in the server, open or close a latch, and so on. v Orange on a component or an orange label on or near a component indicates that the component can be hot-swapped, which means that if the server and operating system support hot-swap capability, you can remove or install the component while the server is running. (Orange can also indicate touch points on hot-swap components.) See the instructions for removing or installing a specific hot-swap component for any additional procedures that you might have to perform before you remove or install the component. v When you are finished working on the server, reinstall all safety shields, guards, labels, and ground wires. v For a list of supported optional devices for the server, see http://www.ibm.com/ servers/eserver/serverproven/compat/us/. System reliability guidelines To help ensure proper cooling and system reliability, make sure that the following requirements are met: v Each of the drive bays has a drive or a filler panel and electromagnetic compatibility (EMC) shield installed in it. v If the server has redundant power, each of the power-supply bays has a power supply installed in it. v There is adequate space around the server to allow the server cooling system to work properly. Leave approximately 50 mm (2.0 in.) of open space around the front and rear of the server. Do not place objects in front of the fans. For proper cooling and airflow, replace the server cover before you turn on the server. Operating the server for extended periods of time (more than 30 minutes) with the server cover removed might damage server components. v You have followed the cabling instructions that come with optional adapters. v You have replaced a failed fan within 48 hours. v You have replaced a hot-swap drive within 2 minutes of removal. v You do not operate the server without the air baffles installed. Operating the server without the air baffles might cause the microprocessors to overheat. Working inside the server with the power on Attention: Static electricity that is released to internal server components when the server is powered-on might cause the server to halt, which could result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when you work inside the server with the power on. You might be instructed to turn on the server while the cover is off, to look at system-board LEDs. Follow these guidelines when you work inside a server that is turned on: v Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved shirts before you work inside the server; do not wear cuff links while you are working inside the server. 12 IBM System x3250 M2 Types 4190 and 4194: Installation Guide

devices
or
components.
v
Blue

a
component
indicates
touch
points,
where
you
can
grip
the
component
to
remove
it
from
or
install
it
in
the

a
component
indicates
that
the
component
can
be
hot-swapped,
which
means
that
if
the

system
support
hot-swap
capability,
you

System
reliability
guidelines
To
help
ensure
proper
cooling
and
system
reliability,
make
sure
that
the
following
requirements
are
met:
v
Each
of
the
drive
bays
has
a
drive
or
a
filler
panel
and
electromagnetic
compatibility
(EMC)
shield
installed
in
it.
v
If
the
server
has
redundant
power,
each
of
the
power-supply
bays
has
a
power
supply
installed
in
it.
v
There
is
adequate
space
around
the
server
to
allow
the
server
cooling
system
to
work
properly.
Leave
approximately
50
mm
(2.0
in.)
of
open
space
around
the
front
and
rear
of
the
server.
Do
not
place
objects
in
front
of
the
fans.
For
proper
cooling
and
airflow,
replace
the
server
cover
before
you
turn
on
the
server.
Operating
the
server
for
extended
periods
of
time
(more
than
30
minutes)
with
the
server
cover
removed
might
damage
server
components.
v
You
have
followed
the
cabling
instructions
that
come
with
optional
adapters.
v
You
have
replaced
a
failed
fan
within
48
hours.
v
You
have
replaced
a
hot-swap
drive
within
2
minutes
of
removal.
v
You
do
not
operate
the
server
without
the
air
baffles
installed.
Operating
the
server
without
the
air
baffles
might
cause
the
microprocessors
to
overheat.
Working
inside
the
server
with
the
power
on
Attention:
Static
electricity
that
is
released
to
internal
server
components
when
the
server
is
powered-on
might
cause
the
server
to
halt,
which
could
result
in
the
loss
of
data.
To
avoid
this
potential
problem,
always
use
an
electrostatic-discharge
wrist
strap
or
other
grounding
system
when
you
work
inside
the
server
with
the
power
on.
You
might
be
instructed
to
turn
on
the
server
while
the
cover
is
off,
to
look
at
system-board
LEDs.
Follow
these
guidelines
when
you
work
inside
a
server
that
is
turned
on:
v
Avoid
wearing
loose-fitting
clothing
on
your
forearms.
Button
long-sleeved
shirts
before
you
work
inside
the
server;
do
not
wear
cuff
links
while
you
are
working
inside
the
server.
