v Blue on a component indicates touch points, were 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 For a list of supported options for the server, go to http://www.ibm.com/servers/ eserver/serverproven/compat/us/ . System reliability guidelines To help ensure proper cooling and system reliability, make sure that: v Each of the drive bays has a drive or a filler panel and electromagnetic compatibility (EMC) shield installed in it. v Each of the power-supply bays has a power supply or power-supply blank 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 turning 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 remove the air baffle while the server is running. Operating the server without the air baffle might cause the microprocessor to overheat. v Microprocessor socket 2 always contains either a microprocessor baffle or a microprocessor and heat sink. Working inside the server with the power on The server supports hot-plug, hot-add, and hot-swap devices and is designed to operate safely while turned on with the cover removed. Follow these guidelines when you work inside a server that is turned on: v Avoid loose-fitting clothing on your forearms. Button long-sleeved shirts before working inside the server; do not wear cuff links while you are working inside the server. v Do not allow your necktie or scarf to hang inside the server. 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. 24 xSeries 346 Types 8840 and 1880: Hardware Maintenance Manual and Troubleshooting Guide

System
reliability
guidelines
To
help
ensure
proper
cooling
and
system
reliability,
make
sure
that:
v
Each
of
the
drive
bays
has
a
drive
or
a
filler
panel
and
electromagnetic
compatibility
(EMC)
shield
installed
in
it.
v
Each
of
the
power-supply
bays
has
a
power
supply
or
power-supply
blank
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
turning
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
remove
the
air
baffle
while
the
server
is
running.
Operating
the
server
without
the
air
baffle
might
cause
the
microprocessor
to
overheat.
v
Microprocessor
socket
2
always
contains
either
a
microprocessor
baffle
or
a
microprocessor
and
heat
sink.
Working
inside
the
server
with
the
power
on
The
server
supports
hot-plug,
hot-add,
and
hot-swap
devices
and
is
designed
to
operate
safely
while
turned
on
with
the
cover
removed.
Follow
these
guidelines
when
you
work
inside
a
server
that
is
turned
on:
v
Avoid
loose-fitting
clothing
on
your
forearms.
Button
long-sleeved
shirts
before
working
inside
the
server;
do
not
wear
cuff
links
while
you
are
working
inside
the
server.
v
Do
not
allow
your
necktie
or
scarf
to
hang
inside
the
server.
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.
