Identifying Problems Using Status LEDs

LED Diagnostics

The diagnostics

built

into your

Netfinity

5000

server

allow

you

to quickly

type

of system

error

that

occurred. When

the System

Error

LED

on

the

LED panel is illuminated, use

the

following

information

to

isolate

the

pro

error

message usually

appears on

the display monitor

as

well.

ŸIf the System Error LED on the information LED panel on the front of

Netfinity

5000

server is

on,

a

system

error was detected. Check the

the power supplies and at any

Ethernet

adapters,

then

open

the

cov

check to see which of the LEDs on

the system board inside the Ne

server are on. (See “System Board LEDs”

on

page 168

for

the

locatio

LEDs.)

on

Actions:

If

the problem

persists, have the system serviced.

NMI

LED

on

A non-maskable interrupt

occurred. The

PCI

1

or PCI

2 LED

will probably also be on.

Actions:

1. If

the

PCI

1 or PCI 2 LED is on, follow the

instructions for

those

LEDs.

2. If

the

PCI

1

or PCI 2 LED is not

on,

restart

th

Netfinity

5000

server. If the

problem

persists (the

NMI

LED stays

on),

have

the

system

serviced.

SMI

LED

on

A

system-management

interrupt

occurred. This

is

an

indication

of

service

processor

activity, and is not an error.

Actions:

No action

is

required.

PCI

1

LED

on

An

error

occurred

on PCI bus 0. An adapter

in

PCI slot

5

system board caused the error.

Actions:

Check

the

error

log for additional information. If th

error log indicates a problem with the integrated

Ethernet

controller,

have

your

system

serviced.

If the

problem

persists,

have

the

system

serviced.

PCI

2

LED

on

An

error

occurred on PCI

Bus

1.

An

adapter in

PCI slot

1

or 4 or the system

board

caused

the

error.

Actions:

1. Check

the error

log

for additional

information.

2. If you cannot correct the problem from the

information

in

the error log, try to determine the

failing adapter

by

removing

one

adapter

at

a time

from the secondary PCI bus (PCI slots 1–4) and

restarting the Netfinity 5000 server after each

adapter

is removed.

If the

problem

persists, have the system serviced.

DIMM

1

Error

LED

on

The DIMM

in

DIMM slot

1

has

failed.

Action: Replace the DIMM in DIMM slot 1.

DIMM 2 Error LED on The DIMM in DIMM slot 2 has failed.

Action: Replace the DIMM in DIMM slot 2.

DIMM 3 Error LED on The DIMM in DIMM slot 3 has failed.

Action: Replace the DIMM in DIMM slot 3.

DIMM 4 Error LED on The DIMM in DIMM slot 4 has failed.

Action: Replace the DIMM in DIMM slot 4.
