If
you
have
just
plugged
the
power
cords
of
the
server
into
an
electrical
outlet,
you
must
wait
30
seconds
before
pressing
the
power-control
button.
The
following
illustration
shows
the
locations
of
the
input
and
output
connectors
on
your
server.
See

Updating
your
server
configuration
When
you
start
your
server
for
the
first
time
after
you
add
or
remove
an
internal
option
or
an
external
SCSI
device,
you
might
see
a
message
telling
you
that
the
configuration
has
changed
(see
“Using
the
Configuration/Setup
Utility
program”
on
page
12).
Some
options
have
device
drivers
that
you
need
to
install.
See
the
documentation
that
comes
with
your
option
for
information
about
installing
any
required
device
drivers.
If
your
server
comes
with
two
microprocessors
or
if
your
server
comes
with
one
microprocessor
and
you
have
installed
one
or
more
additional
microprocessors,
your
server
can
now
operate
as
an
SMP
server.
Therefore,
you
might
need
to
upgrade
your
operating
system
to
support
SMP.
See
the
User’s
Guide
on
the
IBM
xSeries
Documentation
CD
and
your
operating-system
documentation
for
additional
information.
If
you
have
a
RAID
configuration
on
your
server
using
the
integrated
SCSI
controller
and
you
have
installed
or
removed
a
hard
disk
drive,
you
might
need
to
reconfigure
your
disk
arrays.
See
the
RAID
documentation
on
the
IBM
xSeries
Documentation
CD
for
information
about
reconfiguring
your
disk
arrays.
If
you
install
a
different
type
of
RAID
adapter
in
your
server,
use
the
configuration
method
supplied
with
the
RAID
adapter
to
view
or
change
SCSI
settings
for
attached
devices.
The
internal
hard
disk
drives
can
connect
only
to
the
integrated
SCSI
controller
with
RAID
capabilities.
