Notes: a. When you turn on the server, check the hard disk drive status LEDs 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. b. If the server will be configured for RAID operation using the integrated SCSI controller with RAID capabilities or an optional ServeRAID™ controller, you must configure the disk arrays before installing the operating system. See the ServeRAID documentation on the IBM ServeRAID Support CD for additional information about RAID operation and complete instructions for using ServeRAID Manager. 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 400 MHz, 1.8 V, 240-pin, single-stacked, double-data-rate (DDR) II, registered synchronous dynamic random-access memory (SDRAM) with error correcting code (ECC) DIMMs. These DIMMs must be compatible with the latest PC3200 SDRAM Registered DIMM specification. For a list of supported options for the server, go to http://www.ibm.com/us/compat/. v The server comes with a minimum of two 512 MB DIMMs, installed in slots 1 and 2. When you install additional DIMMs, be sure to install them in pairs. All the DIMMs in a single pair must be the same size and type. You can mix compatible DIMMs from various manufacturers. Table 2. DIMM installation sequence Pair DIMM connectors 1 1 and 2 3 5 and 6 Pair DIMM connectors 2 3 and 4 4 7 and 8 v The second pair does not have to contain DIMMs of the same size, speed, type, and technology as the first pair. v The server supports Chipkill™ memory if all DIMMs are type x4 and larger than 512 MB. Using any 256 MB DIMMs, or any DIMM that is not of type x4, disables Chipkill memory. Table 3.

Notes:
a.
When
you
turn
on
the
server,
check
the
hard
disk
drive
status
LEDs
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.
b.
If
the
server
will
be
configured
for
RAID
operation
using
the
integrated
SCSI
controller
with
RAID
capabilities
or
an
optional
ServeRAID
™
controller,
you
must
configure
the
disk
arrays
before
installing
the
operating
system.
See
the
ServeRAID
documentation
on
the
IBM
ServeRAID
Support
CD
for
additional
information
about
RAID
operation
and
complete
instructions
for
using
ServeRAID
Manager.
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

II,
registered
synchronous
dynamic
random-access
memory
(SDRAM)
with
error
correcting
code
(ECC)
DIMMs.
These
DIMMs
must
be
compatible
with
the
latest
PC3200
SDRAM
Registered
DIMM
specification.
For
a
list
of
supported
options
for
the
server,
go
to
v
The
server
comes
with
a
minimum
of
two
512
MB
DIMMs,
installed
in
slots
1
and
2.
When
you
install
additional
DIMMs,
be
sure
to
install
them
in
pairs.
All
the
DIMMs
in
a
single
pair
must
be
the
same
size
and
type.
You
can
mix
compatible
DIMMs
from
various
manufacturers.
