Note:
If
multiple
I/O
planars
or
I/O
Drawer
DCAs
are
being
replaced
during
a
maintenance
window,
then
they
must
be
replaced
one
at
a
time
in
order
to
ensure
the
I/O
Drawer
serial
number
does
not
become
damaged.
After
a
single
part
is
replaced,
the
I/O
drawer
needs
to
have
power
applied
to
it
and
the
system
brought
to
the
OK
prompt.
At
this
point,
the
system
can
be
powered
off
to
replace
the
next
part.
An
algorithm
is
used
(shortly
after
the
UEPO
is
turned
on)
to
overwrite
the
new
part.
If
more
than
one
part
is
replaced
at
a
time,
the
VPD
will
not
be
updated
and
the
system
will
not
be
able
to
boot
in
LPAR
mode.

Note:
If
the
I/O
subsystem
is

of
the
rack,
the
I/O
subsystem
may
need
to
be
removed
from
the
rack

of
the
I/O
subsystem
backplane
removal
tool
to
install
a
new
I/O
backplane.
