Adapter
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
434
and
“Installing
a
Hot-Pluggable
PCI
Adapter”
on
page
433.
To
replace
an
adapter,
perform
the
following
steps:
1.
Place
the
I/O
drawer
in
the
rear
service
position:
a.
If
you
have
not
already
done
so,
open
the
front
door
of
the
rack
unit.
b.
Loosen
the
two
thumbscrews
that
attach
the
front
bezel
to
the
drawer.
c.
Grasp
both
sides
of
the
front
bezel
and
pull
the
bezel
off
the
drawer.
d.
If
you
have
not
already
done
so,
open
the
rear
door
of
the
rack
unit.
e.
If
present,
remove
the
two
retaining
screws
that
secure
the
drawer
to
the
rails.
Refer
to
“Rear
Service
Position”
on
page
465.
f.
Ensure
that
the
cables
do
not
restrain
drawer
movement.
g.
Grasp
the
bar
at
the
rear
of
the
drawer,
and
pull
the
drawer
to
the
rear
until
it
is
stopped
by
the
detents.
2.
Remove
the
two
thumbscrews,
and
remove
the
top
cover
from
the
drawer.
3.
Determine
the
slot
from
which
you
are
removing
the
adapter.
4.
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.
For
additional
information
about
taking
an
adapter
offline
or
removing
it
from
the
system
configuration,
see
the
AIX
System
Management
Guide:

System

Devices
