Ethernet
switch
module
configuration
planning
One
Ethernet
switch
module
is
required
in
switch
module
bay
1
of
your
BladeCenter
unit.
The
switch
module
provides
four
external
Ethernet
ports,
which
you
can
use
to
communicate
with
an
external
Ethernet
network.
In
addition,
the
switch
module
provides
14
internal
Ethernet
ports,
which
are
used
to
communicate
with
each
of
the
blade
servers
in
your
BladeCenter
unit.
Note:
Enumeration
of
the
Ethernet
controllers
is
operating-system
dependent.
for
example,
the
Ethernet
controller
located
nearer
the
top
of
the
blade
server
whose
communications
are
routed
through
Ethernet
switch
module
1,
is
designated
as
the
first
connection
(or
Local
Area
Connection)
by
Microsoft
Windows
2000,
but
is
designated
as
the
second
connection
(or
eth1)
by
Red
Hat
Linux
Version
7.3.
The
Ethernet
controller
located
nearer
the
bottom
of
the
blade
server,
whose
communications
are
routed
through
Ethernet
Switch
module
2,
is
designated
as
the
second
connection
(or
Local
Area
Connection
2)
by
Microsoft
Windows
2000,
but
is
designated
as
the
first
connection
(or
eth0)
by
Red
Hat
Linux
Version
7.3.
Options
that
you
can
configure
for
the
Ethernet
switch
module
include:
v
Switch
settings
v
