Working with adapters The server comes with adapter connectors, called slots. The AGP video adapter is installed in the AGP slot. You can install up to five PCI adapters in PCI slots 1 through 5. All PCI expansion slots are 32-bit, 33 MHz slots. Note: The illustrations in this document might differ slightly from your hardware. The following illustration shows the location of the system expansion slots on the system and PCI extender boards. AGP slot PCI slot 1 PCI slot 2 PCI slot 3 PCI slot 4 PCI slot 5 Adapter considerations Before you install an adapter, review the following: v Locate the documentation that comes with the adapter and follow those instructions in addition to the instructions given in this chapter. If you need to change the switch or jumper settings on your adapter, follow the instructions that come with the adapter. v You can install full-length adapters in all five PCI expansion slots. v The server supports 5.0 V and universal PCI adapters; it does not support 3.3 V adapters. v The server uses a rotational interrupt technique to configure PCI adapters. Because of this technique, you can install a variety of PCI adapters that currently do not support sharing of PCI interrupts. v If you are installing or replacing an adapter that will control your startup (boot) drive, install the adapter in PCI expansion slot 2. v PCI expansion slots 1 through 5 are on PCI bus 0. The system scans the AGP slot and PCI expansion slots 1 through 5 to assign system resources; then, the system starts (boots) the PCI devices in the following order, if you have not 46 xSeries 200 Type 8479 and xSeries 200VL Type 8481: Hardware Maintenance Manual

Working
with
adapters
The
server
comes
with
adapter
connectors,
called
slots
.
The
AGP
video
adapter
is
installed
in
the
AGP
slot.
You
can
install
up
to
five
PCI
adapters
in
PCI
slots
1
through
5.
All
PCI
expansion
slots
are
32-bit,
33
MHz
slots.
Note:
The
illustrations
in
this
document
might
differ
slightly
from
your
hardware.
The
following
illustration
shows
the
location
of
the

Adapter
considerations
Before
you
install
an
adapter,
review
the
following:
v
Locate
the
documentation
that
comes
with
the
adapter
and
follow
those
instructions
in
addition
to
the
instructions
given
in
this
chapter.
If
you
need
to
change
the
switch
or
jumper
settings
on
your
adapter,
follow
the
instructions
that
come
with
the
adapter.
v
You
can
install
full-length
adapters
in
all
five
PCI
expansion
slots.
v
The
server
supports
5.0
V
and
universal
PCI
adapters;
it
does
not
support
3.3
V
adapters.
v
The
server
uses
a
rotational
interrupt
technique
to
configure
PCI
adapters.
Because
of
this
technique,
you
can
install
a
variety
of
PCI
adapters
that
currently
do
not
support
sharing
of
PCI
interrupts.
v
If
you
are
installing
or
replacing
an
adapter
that
will
control
your
startup
(boot)
drive,
install
the
adapter
in
PCI
expansion
slot
2.
v
PCI
expansion
slots
1
through
5
are
on
PCI
bus
0.
The
system
scans
the
AGP
slot
and
PCI
expansion
slots
1
through
5
to
assign
system
resources;
then,
the
system
starts
(boots)
the
PCI
devices
in
the
following
order,
if
you
have
not
