I/O
Subsystem
Distributed
Converter
Assembly
(DCA)
Notes:
1.
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.
2.
Each
I/O
subsystem
can
have
up
to
two
DCAs.
You
can
replace
each
DCA
separately.
The
removal
and
replacement
procedures
are
identical
for
each
DCA.
3.
This
procedure
applies
to
the
I/O
subsystem
DCAs.
4.
If
a
subsystem
has
two
DCAs,
each
is
hot-pluggable.
If
only
one
needs
to
be
removed,
you
do
not
have
to
power
off
the
system.
Do
not
attempt
to
replace
two
DCAs
at
once
or
to
move
DCAs
from
one
I/O
drawer
to
another
to
troubleshoot
a
problem.
The
machine
type/serial
number
will
be
damaged
when
these
actions
are
attempted.
Removal
DANGER
Do
not
attempt
to
open
the
covers
of
the
power
supply.
Power
supplies
are
not
serviceable
and
are
to
be
replaced
as
a
unit.
