Deleting a scalable partition Complete the following steps to delete the scalable partition: 1. Start the Configuration/Setup Utility on the primary server. 2. From the main menu, select Advanced Setup. 3. Select Scalable Partition Settings. 4. Select either Delete ALL Scalable Partition or Delete ONLY Local Scalable Partition. Note: Do not select Write Scalable Partition Settings when you delete the scalable partition. 5. Exit the Configuration/Setup Utility program. 6. Turn off the servers. 7. If necessary, remove the SMP Expansion cables and reconnect them according to your new configuration. See "Connecting the cables" on page 126 for instructions. 8. Restart the servers. Power cabling The server uses two power cords that can be connected to a primary power unit inside the rack cabinet, such as a properly grounded power distribution unit or uninterruptible power supply, or to an external source, such as a properly grounded electrical outlet. Complete the following steps to attach the power-supply cords: 1. Connect a power-supply cord to one of the system power connectors on the rear of the server. 2. Connect the other end of the power-supply cord to a properly grounded electrical outlet or a primary power unit inside the rack cabinet. Note: Connecting the power-supply cords to an electrical outlet might cause the server to start automatically. This is an acceptable action. See "Turning on the server" in the User's Guide on the IBM xSeries Documentation CD for detailed information about turning on the server. 3. Repeat steps 1 and 2 for the second cable. Note: The xSeries 445 server requires a 220 V ac power connection for full power-supply redundancy. Whenever possible, use a 220 V ac connection for all configurations. However, you can use a 110 V ac connection, but without full power-supply redundancy. SCSI cabling The server has one SCSI connector located on the back of the server. Use this connector to connect the server to an optional SCSI device such as one of the IBM external storage enclosures. For detailed information about this option and how to connect it to the server, see the documentation that comes with the SCSI device. Chapter 4. Installing options 143

Deleting
a
scalable
partition
Complete
the
following
steps
to
delete
the
scalable
partition:
1.
Start
the
Configuration/Setup
Utility
on
the
primary
server.
2.
From
the
main
menu,
select
Advanced
Setup
.
3.
Select
Scalable
Partition
Settings
.
4.
Select
either
Delete
ALL
Scalable
Partition
or
Delete
ONLY
Local
Scalable
Partition
.
Note:
Do
not
select
Write
Scalable
Partition
Settings
when
you
delete
the
scalable
partition.
5.
Exit
the
Configuration/Setup
Utility
program.
6.
Turn
off
the
servers.
7.
If
necessary,
remove
the
SMP
Expansion
cables
and
reconnect
them
according
to
your
new
configuration.
See
“Connecting
the
cables”
on
page
126
for
instructions.
8.
Restart
the
servers.
Power
cabling
The
server
uses
two
power
cords
that
can
be
connected
to
a
primary
power
unit
inside
the
rack
cabinet,
such
as
a
properly
grounded
power
distribution
unit
or
uninterruptible
power
supply,
or
to
an
external
source,
such
as
a
properly
grounded
electrical
outlet.
Complete
the
following
steps
to
attach
the
power-supply
cords:
1.
Connect
a
power-supply
cord
to
one
of
the
system
power
connectors
on
the
rear
of
the
server.
2.
Connect
the
other
end
of
the
power-supply
cord
to
a
properly
grounded
electrical
outlet
or
a
primary
power
unit
inside
the
rack
cabinet.
Note:
Connecting
the
power-supply
cords
to
an
electrical
outlet
might
cause
the
server
to
start
automatically.
This
is
an
acceptable
action.
See
“Turning
on
the
server”
in
the
User’s
Guide
on
the
IBM
xSeries
Documentation
CD
for
detailed
information
about
turning
on
the
server.
3.
Repeat
steps
1
and
2
for
the
second
cable.
Note:
The
xSeries
445
server
requires
a
220
V
ac
power
connection
for
full
power-supply
redundancy.
Whenever
possible,
use
a
220
V
ac
connection
for
all
configurations.
However,
you
can
use
a
110
V
ac
connection,
but
without
full
power-supply
redundancy.
SCSI
cabling
The
server
has
one
SCSI
connector
located
on
the
back
of
the
server.
Use
this
connector
to
connect
the
server
to
an
optional
SCSI
device
such
as
one
of
the
IBM
external
storage
enclosures.
For
detailed
information
about
this
option
and
how
to
connect
it
to
the
server,
see
the
documentation
that
comes
with
the
SCSI
device.
