Ping
an
external
computer
on
the
network
connected
to
the
switch
module
or
pass-thru
module.
If
you
can
ping
the
external
computer,
the
Ethernet
controller
that
you
enabled
is
associated
with
the
switch
module
or
pass-thru
module
in
I/O-module
bay
1.
The
other
Ethernet
controller
in
the
blade
server
is
associated
with
the
switch
module
or
pass-thru
module
in
I/O-module
bay
2.
If
you
have
installed
an
I/O-expansion
card
in
the
blade
server,
communications
from
the
expansion
card
are
routed
to
I/O-module
bays
3
and
4,
if
these
bays
are
supported
by
your
BladeCenter
unit.
You
can
verify
which
controller
on
the
card
is
routed
to
which
I/O-module
bay
by
performing
the
same
test
and
using
a
controller
on
the
expansion
card
and
a
compatible
switch
module
or
pass-thru
module
in
I/O-module
bay
3
or
4.

installed
in
both
the
blade
server
and
the
MPE
unit.
You
can
configure
a
SAS
RAID
array
for
your
blade
server.
You
can
use
two
SAS
hard
disk
drives
in
the
blade
server
to
implement
and
manage
a
RAID
level-0
(striping)
