IBM JS20 Hardware Maintenance Manual - Page 28

Note:

The

BladeCenter

unit

supports

up

to

four

Ethernet

switch

modules.

The

SOL

feature

is

accessed

through

the

Management

Module

Command-Line

Interface.

For

information

about

using

the

command-line

interface,

see

“Using

the

command-line

interface”

and

the

IBM

Eserver

BladeCenter

and

BladeCenter

on

the

IBM

BladeCenter

Documentation

CD.

Using

the

command-line

interface

The

IBM

Eserver

BladeCenter

Management

Module

Command-Line

Interface

provides

direct

access

to

BladeCenter

management

functions

as

an

alternative

to

using

the

Web

interface.

Using

the

command-line

interface,

you

can

issue

commands

to

control

the

power

and

configuration

of

the

blade

server

and

other

components

installed

in

the

BladeCenter

unit.

The

command-line

interface

also

provides

access

to

the

text-console

command

prompt

for

the

blade

server

through

an

SOL

connection.

See

the

IBM

Eserver

BladeCenter

and

the

IBM

BladeCenter

Documentation

CD

for

information

and

instructions.

Configuring

the

Gigabit

Ethernet

controller

One

dual-port

Gigabit

Ethernet

controller

is

integrated

on

the

blade

server

system

board.

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,

which

enables

simultaneous

transmission

and

reception

of

data

on

the

Ethernet

local

area

network

(LAN).

Each

Ethernet

controller

port

on

the

system

board

is

routed

to

a

different

switch

module

in

I/O

bay

1

or

bay

2.

The

routing

from

the

Ethernet

controller

port

to

the

I/O

bay

will

vary

based

on

blade

server

type

and

the

operating

system

that

is

installed.

See

“Blade

server

Ethernet

controller

enumeration”

on

page

19

for

information

about

how

to

determine

the

routing

from

the

Ethernet

controller

ports

to

I/O

bays

for

the

blade

server.

Note:

Other

types

of

blade

servers,

such

as

the

BladeCenter

HS20

Type

8678,

that

are

installed

in

the

same

BladeCenter

unit

as

this

BladeCenter

JS20

Type

8842

might

have

different

requirements

for

Ethernet

controller

routing.

See

the

documentation

that

comes

with

the

other

blade

servers

for

detailed

information.

You

do

not

need

to

set

any

jumpers

or

configure

the

controllers

for

the

blade

server

operating

system.

However,

you

must

install

a

device

driver

to

enable

the

blade

server

operating

system

to

address

the

Ethernet

controller

ports.

For

device

drivers

and

information

about

configuring

the

Ethernet

controller

ports,

see

the

Ethernet

software

documentation

that

comes

with

the

blade

server,

or

contact

your

reseller

or

IBM

marketing

representative.

For

updated

information

about

configuring

the

controllers,

go

to

the

IBM

Support

Web

site

at

http://www.ibm.com/support/.

The

Ethernet

controller

supports

failover,

which

provides

automatic

redundancy

for

the

Ethernet

controller

ports.

Without

failover

you

can

have

only

one

Ethernet

controller

port

from

each

server

attached

to

each

virtual

LAN

or

subnet.

With

failover

you

can

configure

more

than

one

Ethernet

controller

port

from

each

server

to

attach

to

the

same

virtual

LAN

or

subnet.

Either

one

of

the

integrated

Ethernet

controller

ports

can

be

configured

as

the

primary

Ethernet

controller

port.

If

you

have

configured

the

controller

ports

for

failover

and

the

primary

link

fails,

the

secondary

controller

port

takes

over.

When

the

primary

link

is

restored,

the
