Installing an adapter The following notes describe the types of adapters that the server supports and other information that you must consider when installing an adapter: v Locate the documentation that comes with the adapter and follow those instructions in addition to the instructions in this section. If you have to change switch settings or jumper settings on the adapter, follow the instructions that come with the adapter. v The adapter slots are on the riser-card assembly. You must first remove the riser-card assembly to access the adapter slots. v Depending on the riser-card assembly in the server, the server contains either two peripheral component interconnect-extended (PCI-X) adapter slots or one PCI-X slot and one PCI Express slot. See the ServerProven list at http://www.ibm.com/servers/eserver/serverproven/compat/us/ for a list of riser cards and adapters that you can use with the server. v You can install one full-height three-quarter-length adapter in expansion slot 1 and one low-profile half-length adapter in expansion slot 2. v The server supports the following adapters: - PCI-X: 3.3 V or universal adapters - PCI Express: PCI Express x8 1.0a adapters Note: If you use a legacy PCI adapter (32 bit/33 MHz) or a slower-speed PCI-X adapter in a hot-swap SAS/SATA system, the hard-disk drive performance will be degraded. v The server uses a rotational interrupt technique to configure PCI-X adapters so that you can install PCI-X adapters that do not support sharing of PCI-X interrupts. v The optional Remote Supervisor Adapter II can be installed only in PCI-X slot 1. v You can install an optional RAID controller to enable you to configure the internal hard disk drives into disk arrays. See your RAID controller option documentation for complete instructions for installing a RAID controller and for additional information about RAID controllers. Note: Some operating systems, such as SCO 6.0 and UnixWare 7.14, do not support RAID. See http://www.ibm.com/servers/eserver/serverproven/compat/us/ to determine whether a supported operating system supports RAID. v The optional ServeRAID™ -7t SATA controller can be installed only in PCI-X slot 2. The low-profile bracket that comes with the controller is required for you to install the controller. v The optional ServeRAID 8i controller can be installed only in PCI-X slot 2. The low-profile bracket that comes with the controller is required for you to install the controller. Remove the large expansion-slot bracket that comes preinstalled on the controller, and install the low-profile bracket. v The server scans the PCI-X slots to assign system resources. If you have not changed the default startup sequence, the server starts the devices in the following order: the CD drive first; then, depending on the model, the PCI-X slots 1 and 2, or the PCI-X slot and the PCI Express slot, and then the integrated Ethernet controllers.

Installing
an
adapter
The
following
notes
describe
the
types
of
adapters
that
the
server
supports
and
other
information
that
you
must
consider
when
installing
an
adapter:
v
Locate
the
documentation
that
comes
with
the
adapter
and
follow
those
instructions
in
addition
to
the
instructions
in
this
section.
If
you
have
to
change
switch
settings
or
jumper
settings
on
the
adapter,
follow
the
instructions
that
come
with
the
adapter.
v
The
adapter
slots
are
on
the
riser-card
assembly.
You
must
first
remove
the
riser-card
assembly
to
access
the
adapter
slots.
v
Depending
on
the
riser-card
assembly
in
the
server,
the
server
contains
either
two
peripheral
component
interconnect-extended
(PCI-X)
adapter
slots
or
one
PCI-X
slot
and
one
PCI
Express
slot.
See
the
ServerProven
list
at
for
a
list
of
riser
cards
and
adapters
that
you
can
use
with
the
server.
v
You
can
install
one
full-height
three-quarter-length
adapter
in
expansion
slot
1
and
one
low-profile
half-length
adapter
in
expansion
slot
2.
v
The
server
supports
the
following
adapters:
–
PCI-X:
3.3
V
or
universal
adapters
–
PCI
Express:
PCI
Express
x8
1.0a
adapters
Note:
If
you
use
a
legacy
PCI
adapter
(32
bit/33
MHz)
or
a
slower-speed
PCI-X
adapter
in
a
hot-swap
SAS/SATA
system,
the
hard-disk
drive
performance
will
be
degraded.
v
The
server
uses
a
rotational
interrupt
technique
to
configure
PCI-X
adapters
so
that
you
can
install
PCI-X
adapters
that
do
not
support
sharing
of
PCI-X
interrupts.
v
The
optional
Remote
Supervisor
Adapter
II
can
be
installed
only
in
PCI-X
slot
1.
v
You
can
install
an
optional
RAID
controller
to
enable
you
to
configure
the
internal
hard
disk
drives
into
disk
arrays.
See
your
RAID
controller
option
documentation
for
complete
instructions
for
installing
a
RAID
controller
and
for
additional
information
about
RAID
controllers.
Note:
Some
operating
systems,
such
as
SCO
6.0
and
UnixWare
7.14,
do
not
support
RAID.
See
to
determine
whether
a
supported
operating
system
supports
RAID.
v
The
optional
ServeRAID
™
-7t
SATA
controller
can
be
installed
only
in
PCI-X
slot
2.
The
low-profile
bracket
that
comes
with
the
controller
is
required
for
you
to
install
the
controller.
v
The
optional
ServeRAID
8i
controller
can
be
installed
only
in
PCI-X
slot
2.
The
low-profile
bracket
that
comes
with
the
controller
is
required
for
you
to
install
the
controller.
Remove
the
large
expansion-slot
bracket
that
comes
preinstalled
on
the
controller,
and
install
the
low-profile
bracket.
v
The
server
scans
the
PCI-X
slots
to
assign
system
resources.
If
you
have
not
changed
the
default
startup
sequence,
the
server
starts
the
devices
in
the
following
order:
the
CD
drive
first;
then,
depending
on
the
model,
the
PCI-X
slots
1
and
2,
or
the
PCI-X
slot
and
the
PCI
Express
slot,
and
then
the
integrated
Ethernet
controllers.
