SB2,
and
SB3
only.
Attention:
The
type
2620
or
type
2628
cryptographic
I/O
processor
should
not
be
removed
or
disconnected
except
by
qualified
IBM
service
personnel.
Performing
this
action
for
any
reason
causes
the
loss
of
the
primary
encryption
key.
Before
disconnecting
or
removing
the
cryptographic
I/O
processor,
ensure
that
the
customer
has
access
to
a
record
of
the
primary
encryption
key.
After
any
service
action
that
involves
disconnecting
or
removing
the
processor,
the
customer
must
reinstall
the
primary
encryption
key.
This
is
the
only
way
that
the
customer
can
access
the

Each
system
will
always
have
at

The
first
partition
in
the
system
will
always
be
named

Some
systems
have
the
primary
partition
and
multiple
