8. Set any jumpers or switches on the IDE drive. Important: Both IDE drives must be set to Master. Attention: Do not press on the top of the IDE drive. Pressing the top could damage the drive. 9. Place the IDE drive into the tray and push it, from the rear edge of the drive, into the connector on the riser card until the IDE drive moves past the lever at the back of the tray. The drive clicks into place. 10. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on page 35. Installing memory modules The following notes describe the types of dual inline memory modules (DIMMs) that your blade server supports and other information that you must consider when installing DIMMs: v The system board contains four DIMM connectors and supports two-way memory interleaving. v The DIMM options that are available for your blade server are 256 MB, 512 MB, 1 GB, and 2 GB. Your blade server supports a minimum of 512 MB and a maximum of 8 GB of system memory. v Your blade server comes with two DIMMs in the DIMM 3 (J2) and DIMM 4 (J6) memory connectors. When you install additional DIMMs, be sure to install them as a pair, in DIMM connectors 1 (J1) and 2 (J5). Install the DIMMs in the following order: Pair First Second DIMM connectors 3 (J2) and 4 (J6) 1 (J1) and 2 (J5) v When you install memory, you must install a pair of matched DIMMs. v Both DIMMs in a pair must be the same size, speed, type, and technology. You can mix compatible DIMMs from various manufacturers. v The second pair does not have to be DIMMs of the same size, speed, type, and technology as the first pair. v Install only 2.5 V, 184-pin, DDR, PC2100, registered SDRAM with ECC DIMMs. These DIMMs must be compatible with the latest PC2100 SDRAM Registered DIMM specification, which is available from http://www.jedec.org/. For a current list of supported DIMMs for your blade server, see the ServerProven list at http://www.ibm.com/pc/us/compat/. v PC2100 DIMMs are backward-compatible and work in the PC1600 sockets. v Installing or removing DIMMs changes the configuration information for the blade server. Therefore, after installing or removing a DIMM, you must change and save the new configuration information by using the Configuration/Setup Utility program. When you restart the blade server, it displays a message indicating that the memory configuration has changed. Start the Configuration/Setup Utility program and select Save Settings. See "Configuration/Setup Utility menu choices" on page 44 for more information. Chapter 3. Installing options 25

Installing
memory
modules
The
following
notes
describe
the
types
of
dual
inline
memory
modules
(DIMMs)
that
your
blade
server
supports
and
other
information
that
you
must
consider
when
installing
DIMMs:
v
The
system
board
contains
four
DIMM
connectors
and
supports
two-way
memory
interleaving.
v
The
DIMM
options
that
are
available
for
your
blade
server
are
256
MB,
512
MB,
1
GB,
and
2
GB.
Your
blade
server
supports
a
minimum
of
512
MB
and
a
maximum
of
8
GB
of
system
memory.
v
Your
blade
server
comes
with
two
DIMMs
in
the
DIMM
3
(J2)
and
DIMM
4
(J6)
memory
connectors.
When
you
install
additional
DIMMs,
be
sure
to
install
them
as
a
pair,
in
DIMM
connectors
1
(J1)
and
2
(J5).
Install
the
DIMMs
in
the
following
order:
Pair
DIMM
connectors
First
3
(J2)
and
4
(J6)
Second
1
(J1)
and
2
(J5)
v
When
you
install
memory,
you
must
install
a
pair
of
matched
DIMMs.
v
Both
DIMMs
in
a
pair
must
be
the
same
size,
speed,
type,
and
technology.
You
can
mix
compatible
DIMMs
from
various
manufacturers.
v
The
second
pair
does
not
have
to
be
DIMMs
of
the
same
size,
speed,
type,
and
technology
as
the
first
pair.
v
Install
only
2.5
V,
184-pin,
DDR,
PC2100,
registered
SDRAM
with
ECC
DIMMs.
These
DIMMs
must
be
compatible
with
the
latest
PC2100
SDRAM
Registered
DIMM
specification,
which
is
available
from
For
a
current
list
of
supported
DIMMs

list
at
v
PC2100
DIMMs
are
backward-compatible
and
work
in
the
PC1600
sockets.
v
Installing
or
removing
DIMMs
changes
the
configuration
information
for
the
blade
server.
Therefore,
after
installing
or
removing
a
DIMM,
you
must
change
and
save
the
new
configuration
information
by
using
the
Configuration/Setup
Utility
program.
When
you
restart
the
blade
server,
it
displays
a
message
indicating
that
the
memory
configuration
has
changed.
Start
the
Configuration/Setup
Utility
program
and
select
Save
Settings
.
