SMP Expansion Port cabling for one server with two SMP Expansion Modules: Complete the following steps to cable two SMP Expansion Modules in a single server together, using the two 25.4 cm (10 in.) SMP Expansion cables, for up to 8-way operation. In the illustration, the SMP Expansion Modules are numbered 0 and 1, from bottom to top. The SMP Expansion Ports are numbered 1 through 3, left to right. If your server comes with two SMP Expansion Modules, the SMP Expansion cables are included with the server. If you purchased a second SMP Expansion Module, the cables are included with the option. 11 2 3 0 1 2 3 Figure 33. SMP Expansion Module numbering 1. Remove the protective covers from the connectors on the ends of the cables. Protective cover Figure 34. SMP Expansion cable with protective cover 2. Connect one end of a 25.4 cm (10 in.) SMP Expansion cable to port 1 of SMP Expansion Module 0; then, connect the opposite end of the cable to port 1 of SMP Expansion Module 1. 3. Connect one end of the second 25.4 cm (10 in.) SMP Expansion cable to port 2 of SMP Expansion Module 0; then, connect the opposite end of the cable to port 2 of SMP Expansion Module 1. 4. If you are connecting an RXE-100 enclosure, go to "RXE Expansion Port cabling for one server with two SMP Expansion Modules" on page 43. If you are not connecting an RXE-100 enclosure, connect all remaining external cables to the server; then, go to "Creating a scalable partition" on page 63 and follow the instructions for creating a scalable partition. Notes: 1. When multiple cables are connected between the SMP Expansion Module ports, SMP data is interleaved between the cables for better performance. 2. The server will start and operate with one cable attached between the two SMP Expansion Modules. 36 xSeries 445 Type 8870: Installation Guide

SMP
Expansion
Port
cabling
for
one
server
with
two
SMP
Expansion
Modules:
Complete
the
following
steps
to
cable
two
SMP
Expansion
Modules
in
a
single
server
together,
using
the
two
25.4
cm
(10
in.)
SMP
Expansion
cables,
for
up
to
8-way
operation.
In
the
illustration,
the
SMP
Expansion
Modules
are
numbered
0
and
1,
from
bottom
to
top.
The
SMP
Expansion
Ports
are
numbered
1
through
3,
left
to
right.
If
your
server
comes
with
two
SMP
Expansion
Modules,
the
SMP
Expansion
cables
are
included
with
the
server.
If
you
purchased
a
second
SMP
Expansion
Module,
the
cables
are
included
with
the
option.
1.
Remove
the
protective
covers
from
the
connectors
on
the
ends
of
the
cables.
2.
Connect
one
end
of
a
25.4
cm
(10
in.)
SMP
Expansion
cable
to
port
1
of
SMP
Expansion
Module
0;
then,
connect
the
opposite
end
of
the
cable
to
port
1
of
SMP
Expansion
Module
1.
3.
Connect
one
end
of
the
second
25.4
cm
(10
in.)
SMP
Expansion
cable
to
port
2
of
SMP
Expansion
Module
0;
then,
connect
the
opposite
end
of
the
cable
to
port
2
of
SMP
Expansion
Module
1.
4.
If
you
are
connecting
an
RXE-100
enclosure,
go
to
“RXE
Expansion
Port
cabling
for
one
server
with
two
SMP
Expansion
Modules”
on
page
43.
If
you
are
not
connecting
an
RXE-100
enclosure,
connect
all
remaining
external
cables
to
the
server;
then,
go
to
“Creating
a
scalable
partition”
on
page
63
and
follow
the
instructions
for
creating
a
scalable
partition.
Notes:
1.
When
multiple
cables
are
connected
between
the
SMP
Expansion
Module
ports,
SMP
data
is
interleaved
between
the
cables
for
better
performance.
2.
The
server
will
start
and
operate
with
one
cable
attached
between
the
two
SMP
Expansion
Modules.
