Drive-tray assembly Drive handle Filler panel Complete the following steps to install a drive in a hot-swap bay. Attention: To maintain proper system cooling, do not operate the server for more than 10 minutes without either a drive or a filler panel installed in each bay. 1. Read the safety information beginning on page Appendix B, "Safety information," on page 117 and "Installation guidelines" on page 23. 2. Remove the filler panel from one of the empty hot-swap bays by inserting your finger into the depression at the left side of the filler panel and pulling it away from the server. 3. Install the hard disk drive in the hot-swap bay: a. Make sure that the tray handle is open (that is, perpendicular to the drive). b. Align the drive assembly with the guide rails in the bay. c. Gently push the drive assembly into the bay until the drive stops. d. Push the tray handle to the closed (locked) position. e. Check the hard disk drive status LED to verify that the hard disk drive is operating properly. If the amber hard disk drive status LED for a drive is lit continuously, that drive is faulty and must be replaced. If the green hard disk drive activity LED is flashing, the drive is being accessed. Note: If you have a RAID configuration using the integrated SCSI controller with RAID capabilities, or if the server has a RAID adapter installed, you might have to reconfigure the disk arrays after installing hard disk drives. See the RAID documentation on the IBM xSeries Documentation CD for information about RAID adapters. Installing memory modules The following notes describe the types of dual inline memory modules (DIMMs) that the server supports and other information that you must consider when installing DIMMs: v The server supports 256 MB, 512 MB, 1 GB, and 2 GB DIMMs, for a maximum of 16 GB of system memory. The server supports up to eight 1.8 V, 240-pin, PC2-3200, ECC DDR II SDRAM, 200 MHz DIMMs. Go to the ServerProven® list at http://www.ibm.com/servers/eserver/serverproven/compat/us/ for a list of memory modules that you can use with the server. v The server comes with a minimum of two 256 MB DIMMs, installed in slots 1 and 2. When installing additional DIMMs, you must install two DIMMS at a time, in the order shown in the following table, to maintain performance. Chapter 4. Installing options 39

Filler panel
Drive-tray assembly
Drive handle
Complete
the
following
steps
to
install
a
drive
in
a
hot-swap
bay.
Attention:
To
maintain
proper
system
cooling,
do
not
operate
the
server
for
more
than
10
minutes
without
either
a
drive
or
a
filler
panel
installed
in
each
bay.
1.
Read
the
safety
information
beginning
on
page
Appendix
B,
“Safety
information,”
on
page
117
and
“Installation
guidelines”
on
page
23.
2.
Remove
the
filler
panel
from
one
of
the
empty
hot-swap
bays
by
inserting
your
finger
into
the
depression
at
the
left
side
of
the
filler
panel
and
pulling
it
away
from
the
server.
3.
Install
the
hard
disk
drive
in
the
hot-swap
bay:
a.
Make
sure
that
the
tray
handle
is
open
(that
is,
perpendicular
to
the
drive).
b.
Align
the
drive
assembly
with
the
guide
rails
in
the
bay.
c.
Gently
push
the
drive
assembly
into
the
bay
until
the
drive
stops.
d.
Push
the
tray
handle
to
the
closed
(locked)
position.
e.
Check
the
hard
disk
drive
status
LED
to
verify
that
the
hard
disk
drive
is
operating
properly.
If
the
amber
hard
disk
drive
status
LED
for
a
drive
is
lit
continuously,
that
drive
is
faulty
and
must
be
replaced.
If
the
green
hard
disk
drive
activity
LED
is
flashing,
the
drive
is
being
accessed.
Note:
If
you
have
a
RAID
configuration
using
the
integrated
SCSI
controller
with
RAID
capabilities,
or
if
the
server
has
a
RAID
adapter
installed,
you
might
have
to
reconfigure
the
disk
arrays
after
installing
hard
disk
drives.
See
the
RAID
documentation
on
the
IBM
xSeries
Documentation
CD
for
information
about
RAID
adapters.
Installing
memory
modules
The
following
notes
describe
the
types
of
dual
inline
memory
modules
(DIMMs)
that
the
server
supports
and
other
information
that
you
must
consider
when
installing
DIMMs:
v
The
server
supports
256
MB,
512
MB,
1
GB,
and
2
GB
DIMMs,
for
a
maximum
of
16
GB
of
system
memory.
The

supports
up
to
eight
1.8
V,
240-pin,
PC2-3200,
ECC
DDR
II
SDRAM,
200
MHz
DIMMs.
Go
to
the
ServerProven
®
list
at

modules
that
you
can
use
with
the
server.
v
The
server
comes
with
a
minimum
of
two
256
MB
DIMMs,
installed
in
slots
1
and
2.
When
installing
additional
DIMMs,
you
must
install
two
DIMMS
at
a
time,
in
the
order
shown
in
the
following
table,
to
maintain
performance.
