Appendix A. Installing and replacing components This appendix provides instructions for installing and replacing hardware components in the storage subsystem. Installation guidelines Before you begin installing options, read the following information: v Read the safety information beginning on page iii and the guidelines in "Handling static-sensitive devices." This information will help you work safely with the server and options. v Make sure that you have an adequate number of properly grounded electrical outlets for your server, external storage subsystem, and other devices. v Back up all important data before you make changes to disk drives. v Have a small flat-blade screwdriver available. v You do not have to turn off the storage subsystem to install or replace a hard disk drive or power supply. v Blue on a component indicates touch points, where you can grip the component to remove it from or install it in the storage subsystem, 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 you can remove or install the component while the storage subsystem 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 storage subsystem, go to http://www.ibm.com/pc/compat/. 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 If the storage subsystem has redundant power, each of the power-supply bays has a power supply installed in it. v There is adequate space around the storage subsystem to allow the storage subsystem cooling system to work properly. Leave approximately 50 mm (2.0 in.) of open space around the front and rear of the storage subsystem. Do not place objects in front of the fans. v You have replaced a failed power supply within 10 minutes of removal. v You have replaced a hot-swap drive within 2 minutes of removal. Handling static-sensitive devices Attention: Static electricity can damage the server and other electronic devices. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them. © Copyright IBM Corp. 2004, 2005 35

Appendix
A.
Installing
and
replacing
components
This
appendix
provides
instructions
for
installing
and
replacing
hardware
components
in
the
storage
subsystem.
Installation
guidelines
Before
you
begin
installing
options,
read
the
following
information:
v
Read
the
safety
information
beginning
on
page
iii
and
the
guidelines
in
“Handling
static-sensitive
devices.”
This
information
will
help
you
work
safely
with
the
server
and
options.
v
Make
sure
that
you
have
an
adequate
number
of
properly
grounded
electrical
outlets
for
your
server,
external
storage
subsystem,
and
other
devices.
v
Back
up
all
important
data
before
you
make
changes
to
disk
drives.
v
Have
a
small
flat-blade
screwdriver
available.
v
You
do
not
have
to
turn
off
the
storage
subsystem
to
install
or
replace
a
hard
disk
drive
or
power
supply.
v
Blue
on
a
component
indicates
touch
points,
where
you
can
grip
the
component
to
remove
it
from
or
install
it
in
the
storage
subsystem,
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
you
can
remove
or
install
the
component
while
the
storage
subsystem
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
storage
subsystem,
go
to
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
If
the
storage
subsystem
has
redundant
power,
each
of
the
power-supply
bays
has
a
power
supply
installed
in
it.
v
There
is
adequate
space
around
the
storage
subsystem
to
allow
the
storage
subsystem
cooling
system
to
work
properly.
Leave
approximately
50
mm
(2.0
in.)
of
open
space
around
the
front
and
rear
of
the
storage
subsystem.
Do
not
place
objects
in
front
of
the
fans.
v
You
have
replaced
a
failed
power
supply
within
10
minutes
of
removal.
v
You
have
replaced
a
hot-swap
drive
within
2
minutes
of
removal.
Handling
static-sensitive
devices
Attention:
Static
electricity
can
damage
the
server
and
other
electronic
devices.
To
avoid
damage,
keep
static-sensitive
devices
in
their
static-protective
packages
until
you
are
ready
to
install
them.
