Appendix
C.
Removing
and
Replacing
PCI
Adapters
This
appendix
contains
removal
and
replacement
procedures
for
PCI
adapters.
Note:
Linux
does
not
support
hot-plugging
any
hot-pluggable
PCI
adapters
or
devices.
A
system
with
Linux
installed
on
one
or
more
partitions
must
be
shut
down
and
powered
off
before
replacing
any
PCI
adapter
or
device
assigned
to
a
Linux
partition.
Follow
the
non-hot-pluggable
adapter
or
device
procedures
when
replacing
a
PCI
adapter
or
device
in
any
partition
with
Linux
installed.
Most
PCI
adapters
can
be
removed
and
replaced,
or
installed
in
the
system
without
turning
off
the
power
to
the
entire
system.
These
adapters
are
referred
to
as
hot-pluggable
PCI
adapters
.
Some
adapters
are
not
hot-pluggable
and
power
must
be
removed
from
the
system
for
adapter
removal,
replacement,
or
installation.
Though
some
adapters
are
not
hot-pluggable,
they
must
still
be
installed
in
the
cassette.
Note:
An
adapter
or
an
adapter
blank
filler
must
be
installed
into
the
PCI
adapter
cassette
assembly
before
it
is
reinstalled
in
a
system
unit
or
an
I/O
drawer.
Before
you
remove
or
replace
an
adapter,
determine
if
the
PCI
adapter
you
are
working
with
is
hot-pluggable.
See
the
PCI
Adapter
Placement
Reference
,
order
number
SA23-2504.
When
assembling,
inserting
or
removing
a
blindswap
cassette,
verify
that
the
foam
″
T-shaped
″
EMC
gasket
strip
is
firmly
attached
to
the
sheet
metal
bezel.
This
includes
all
applications
where
these
gaskets
are
used
(for
example,
riser
cards,
blank
fillers
or
any
of
the
various
cassette
assemblies).
Visually
inspect
the
top
and
bottom
of
the
gasket
strips
insuring
that
they
are
firmly
bonded
to
the
sheet
metal.
Look
for
any
of
the
following:
v
gaskets
that
are
starting
to
unwrap
v
gaskets
lifting
or
peeling
off
of
the
sheet
metal
v
gaskets
protruding
from
the
sheet
metal
bezel
when
all
cassettes,
fillers,
or
risers
are
plugged
into
the
system.
Inspect
both
the
gasket
on
the
cassette
or
filler
that
was
removed
and
the
gasket
visible
in
the
PCI
slot.
If
a
bad
gasket
is
found
on
a
cassette,
then
the
entire
cassette
must
be
replaced
with
a
new
cassette
and
gasket.
If
a
bad
gasket
is
found
on
a
riser
card,
then
the
I/O
Planar
containing
the
riser
card
needs
to
be
replaced.
If
you
are
removing
a
PCI
adapter
that
is:
v
Not
hot-pluggable,
go
to
“Removing
a
Non-Hot-Pluggable
PCI
Adapter”
on
page
133.
v
Hot-pluggable,
go
to
“Hot-Pluggable
PCI
Adapter”
on
page
134.
