If

 

a

 

problem

 

occurs

 

with

 

the

 

10/100/1000

 

Mbps

 

Ethernet

 

controller,

 

use

 

the

 

Ethernet

 

diagnostic

 

program

 

on

 

the

 

 

CD

 

to

 

diagnose

 

the

 

problem.

 

For

 

more

 

information

 

about

 

this

 

CD,

 

see

 

 

 

 

 

 

 

For

 

information

 

about

 

the

 

Ethernet

 

error

 

codes

 

and

 

actions

 

to

 

take,

 

see

 

the

 

documentation

 

on

 

the

 

 

CD.

 

 

 

 

If

 

the

 

Ethernet

 

controller

 

cannot

 

connect

 

to

 

the

 

network,

 

check

 

the

 

following

 

conditions:

 

v

   

Make

 

sure

 

that

 

the

 

cable

 

is

 

installed

 

correctly.

 

The

 

network

 

cable

 

must

 

be

 

securely

 

attached

 

at

 

all

 

connections.

 

If

 

the

 

cable

 

is

 

attached

 

but

 

the

 

problem

 

remains,

 

try

 

a

 

different

 

cable.

 

If

 

you

 

set

 

the

 

Ethernet

 

controller

 

to

 

operate

 

at

 

either

 

100

 

Mbps

 

or

 

1000

 

Mbps,

 

you

 

must

 

use

 

Category

 

5

 

or

 

higher

 

cabling.

 

v

   

Determine

 

whether

 

the

 

hub

 

supports

 

auto-negotiation.

 

If

 

it

 

does

 

not,

 

try

 

configuring

 

the

 

integrated

 

Ethernet

 

controller

 

manually

 

to

 

match

 

the

 

speed

 

and

 

duplex

 

mode

 

of

 

the

 

hub.

 

v

   

Check

 

the

 

Ethernet

 

controller

 

LEDs

 

on

 

the

 

rear

 

of

 

the

 

server.

 

These

 

LEDs

 

indicate

 

whether

 

a

 

problem

 

exists

 

with

 

the

 

connector,

 

cable,

 

or

 

hub.

 

–

   

The

 

Ethernet

 

transmit/receive

 

activity

 

LED

 

on

 

the

 

rear

 

of

 

the

 

server

 

is

 

lit

 

when

 

the

 

Ethernet

 

controller

 

sends

 

or

 

receives

 

data

 

over

 

the

 

Ethernet

 

network.

 

If

 

the

 

Ethernet

 

transmit/receive

 

activity

 

LED

 

is

 

off,

 

make

 

sure

 

that

 

the

 

hub

 

and

 

network

 

are

 

operating

 

and

 

that

 

the

 

correct

 

device

 

drivers

 

are

 

installed.

 

–

   

The

 

Ethernet

 

link

 

status

 

LED

 

on

 

the

 

rear

 

of

 

the

 

server

 

is

 

lit

 

when

 

the

 

Ethernet

 

controller

 

receives

 

a

 

LINK

 

pulse

 

from

 

the

 

hub.

 

If

 

the

 

LED

 

is

 

off,

 

there

 

might

 

be

 

a

 

defective

 

connector

 

or

 

cable

 

or

 

a

 

problem

 

with

 

the

 

hub.

v

   

Make

 

sure

 

that

 

you

 

are

 

using

 

the

 

correct

 

device

 

drivers,

 

which

 

are

 

supplied

 

with

 

your

 

server.

 

v

   

Check

 

for

 

operating-system-specific

 

causes

 

for

 

the

 

problem.

 

v

   

Make

 

sure

 

that

 

the

 

device

 

drivers

 

on

 

the

 

client

 

and

 

server

 

are

 

using

 

the

 

same

 

protocol.

 

v

   

Test

 

the

 

Ethernet

 

controller.

 

The

 

way

 

the

 

Ethernet

 

controller

 

is

 

tested

 

depends

 

on

 

which

 

operating

 

system

 

you

 

are

 

using

 

(see

 

the

 

Ethernet

 

controller
