Ethernet
controller,
switch
module,
and
cabling
requirements
One
dual-port
Gigabit
Ethernet
controller
is
integrated
on
the
BladeCenter
JS20
Type
8842
system
board.
To
support
Ethernet
connections
and
the
Serial
Over
LAN
(SOL)
feature
and
to
configure
the
blade
server,
you
must
install
an
optional
Ethernet-compatible
switch
module,
such
as
the
Nortel
Networks
Layer
2-7
GbE
Switch
Module
for
IBM
Eserver
BladeCenter
or
IBM
4-Port
Gb
Ethernet
Switch
Module
for
BladeCenter,
in
I/O
bay
1
of
the
BladeCenter
unit.
Each
controller
port
provides
a
1000-Mbps
full-duplex
interface
for
connecting
to
one
of
the
Ethernet-compatible
switch
modules
in
I/O
bays
1
and
2.
If
you
plan
to
attach
additional
Ethernet
devices
to
the
blade
server
or
the
BladeCenter
unit,
you
must
install
an
optional
Ethernet-compatible
switch
module,
such
as
the
Nortel
Networks
Layer
2-7
GbE
Switch
Module
for
IBM
Eserver
BladeCenter
or
IBM
4-Port
Gb
Ethernet
Switch
Module
for
BladeCenter,
in
I/O
bay
3
or
4
of
the
BladeCenter
unit,
to
support
these
additional
Ethernet
connections.
The
optional
Ethernet
switch
modules
contain
four
ports
with
RJ-45
connectors.
These
connectors
provide
a
10/100/1000
Base-T
interface
(either
at
half-duplex
or
full
duplex)
for
connecting
twisted-pair
cable
to
the
Ethernet
network.
You
must
purchase
and
install
a
compatible
cable
to
connect
these
devices.
To
connect
an
Ethernet
controller
port
to
a
repeater
or
switch
module,
use
an
unshielded
twisted
pair
(UTP)
cable
with
RJ-45
connectors
at
both
ends.
For
100
Mbps
or
higher
operation,
Category
5
cabling
is
required.
For
10
Mbps
operation,
Category
3
or
Category
5
cabling
is
required.
