You
can
shorten
the
work
time
for
replacing
the
CPU
memory
unit
lower
by
performing
the
work
in
"9.5
Switching
the
microSD
Card."
*2
The
unit
is
mounted
only
in
the
SPARC
M10-4S.
*3
Active/hot
maintenance
is
supported
only
if
the
target
FRU
is
in
a
redundant
configuration.
We
recommend
active/hot
maintenance
that
has
a
short
work
time.
*4
This
is
supported
only
when
used
for
an
internal
disk
that
is
not
a
boot
device
or
for
a
boot
device
that
has
a
redundant
configuration
(RAID
configuration).
We
recommend
active/hot
maintenance
that
has
a
short
work
time.
*5
Maintenance
work
is
performed
using
PHP.
If
the
direct
I/O
function
is
set,
the
PCIe
card
cannot
use
PHP.
*6
The
cable
is
mounted
only
with
a
configuration
of
two
or
more
building
blocks.
*7
This
method
of
maintenance
uses
the
dynamic
reconfiguration
(DR)
function
to
disconnect
the
chassis
requiring
maintenance
from
the
physical
partition.
It
is
available
only
for
a
system
with
a
configuration
of
two
or
more
building
blocks.
