Removing
and
Replacing
a
Hot-Pluggable
PCI
Adapter:
Note:
Use
this
procedure
only
when
you
are
replacing
an
adapter
with
an
identical
adapter.
If
you
are
replacing
an
adapter
with
an
adapter
that
is
not
identical
to
the
adapter
removed,
go
to
“Removing
a
Hot-Pluggable
PCI
Adapter”
on
page
55,
and
then
to
“Installing
a
Hot-Pluggable
PCI
Adapter”
on
page
57.
To
replace
an
adapter,
perform
the
following
steps:
1.
Determine
the
slot
from
which
you
are
removing
the
adapter.
2.
Ensure
that
any
processes
or
applications
that
might
use
the
adapter
are
stopped.
Note:
Removing
a
hot-pluggable
PCI
adapter
requires
the
system
administrator
to
take
the
PCI
adapter
offline
before
performing
any
PCI
adapter
hot-plug
procedures.
Before
taking
an
adapter
offline,
the
devices
attached
to
the
adapter
must
be
taken
offline
as
well.
This
action
prevents
a
service
representative
or
user
from
causing
an
unexpected
outage
for
system
users.
