Configuring the Gigabit Ethernet controllers

The Ethernet controllers are integrated on the system board. They provide an interface for connecting to a 10-Mbps, 100-Mbps, or 1-Gbps network and provide full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the network. If the Ethernet ports in your server support auto-negotiation, the controllers detect the data-transfer rate (10BASE-T, 100BASE-TX, or 1000BASE-T) and duplex mode (full-duplex or half-duplex) of the network and automatically operate at that rate and mode.

You do not need to set any jumpers or configure the controllers. However, you must install a device driver to enable the operating system to address the controllers. For device drivers and information about configuring the Ethernet controllers, see the

Intel Ethernet Software CD that comes with your server. For updated information

about configuring the controllers, go to http://www.ibm.com/pc/support/.

Chapter 3. Diagnostics

This chapter provides basic troubleshooting information to help solve some common problems that might occur with the server.

If you cannot locate and correct the problem using the information in this chapter, see Appendix A, “Getting help and technical assistance,” on page 81 for more information.

General checkout

Follow the checkout procedure for diagnosing hardware problems. Review the following information before performing the checkout procedure:

v Read the safety information beginning at page 83. v The diagnostic programs are on the IBM Enhanced Diagnostics CD. These

programs are the primary method of testing the major components of the server: the system board, Ethernet controller, video controller, RAM, keyboard, mouse (pointing device), serial ports, hard disk drives, and parallel port. Yo u can also use them to test some external devices. If you are not sure whether a problem is caused by the hardware or by the software, you can use the diagnostic programs to confirm that the hardware is working correctly.

v When you run the diagnostic programs, a single problem might cause several

error messages. If you receive several error messages, correct the cause of the first error message. The other error messages might not occur the next time you run the diagnostic programs.

v Before running the diagnostic programs, you must determine whether the failing

server is part of a shared hard disk drive cluster (two or more servers sharing external storage devices). If you suspect that it is part of a cluster, you can run all diagnostic programs except the ones that test the storage unit (that is, a hard disk drive in the storage unit) or the storage adapter that is attached to the storage unit. The failing server might be part of a cluster if any of the following conditions is true:

– The customer identifies the failing server as part of a cluster. – One or more external storage units are attached to the failing server and at

least one of the attached storage units is also attached to another server or unidentifiable device.

– One or more servers are located near the failing server.

Important:

1. For servers that are part of a shared hard disk drive cluster, run one test at a time. Do not run any suite of tests, such as ″quick″ or ″normal″ tests, because this could enable the hard disk drive diagnostic tests.

2. If more than one error code is displayed, correct the first error. The other error codes might not occur the next time you run the diagnostic programs.

3. If the server is suspended and a POST error code is displayed, see “POST error codes” on page 55.

4. If the server is suspended and no error message is displayed, see “Error symptoms” on page 62 and “Undetermined problems” on page 73.

5. For information about power-supply problems, see “Power checkout” on page

26.

6. For intermittent problems, check the error log; see “Diagnostic programs and error messages” on page 20.

Note: The system-error log is available on the xSeries 306 only when the

server has an optional Remote Supervisor Adapter II.

Chapter 3. Diagnostics 19

POST error messages

POST error messages can appear when a problem is detected during startup. For a complete list of POST messages, see “POST error codes” on page 55.

Diagnostic programs and error messages

The system diagnostic programs are on the IBM Enhanced Diagnostics CD. These programs are the primary method of testing the major components of the server.

An IBM Enhanced Diagnostics CD comes with the server. You can also download the latest version of the diagnostic programs from http://www.ibm.com/support/ (see “Downloading the diagnostic program” on page 21).

The IBM Enhanced Diagnostic programs isolate problems from the server hardware and software. The programs run independently of the operating system and must be run either from a CD or diskette.

Diagnostic error messages indicate that a problem exists; they are not intended to be used to identify a failing part. Troubleshooting and servicing complex problems indicated by error messages should be performed by trained service personnel.

Sometimes the first error to occur causes additional errors. In this case, the server displays more than one error message. Always follow the suggested action instructions for the first error message that appears.

Text messages

Error codes that might be displayed are listed at “Diagnostic error codes” on page

58.

The diagnostic text message format is as follows:

Power problems can be difficult to solve. For example, a short circuit can exist anywhere on any of the power distribution buses. Usually, a short circuit will cause the power subsystem to shut down because of an overcurrent condition.

A general procedure for troubleshooting power problems is as follows:

1. Turn off the server, and disconnect all ac power cords.

2. Check for loose cables in the power subsystem. Also check for short circuits, for example, if there is a loose screw causing a short circuit on a circuit board.

3. Remove adapters, and disconnect the cables and power connectors to all internal and external devices until the server is at the minimum configuration required to start the server (see “Minimum operating requirements” on page 73).

4. Reconnect all ac power cords, and turn on the server. If the server starts successfully, replace adapters and devices one at a time until the problem is isolated. If the server does not start from the minimal configuration, replace FRUs of minimal configuration one at a time until the problem is isolated.

To use this method, you must know the minimum configuration that is required for the server to start (see page 73).

Chapter 4. Installing options

This chapter provides detailed instructions for installing hardware options in your server.

Installation guidelines

Before you begin installing options in your server, read the following information:

v Read the safety information beginning on page 83 and the guidelines in

“Handling static-sensitive devices” on page 27. This information will help you work safely with your server and options.

v Make sure that you have an adequate number of properly grounded electrical

outlets for your server, monitor, and other devices that you will connect to the server.

v Back up all important data before you make changes to disk drives. v Have a small flat-blade screwdriver available. v You do not have to turn off the server to install or replace hot-plug Universal

Serial Bus (USB) devices.

v Blue on a component indicates touch points, where you can grip the component

to remove it from or install it in the server, open or close a latch, and so on.

v Orange on a component or an orange label on or near a component indicates

that the component can be hot-swapped, which means that if the server and operating system support hot-swap capability, you can remove or install the component while the server is running. (Orange can also indicate touch points on hot-swap components.) See the instructions for removing or installing a specific hot-swap component for any additional procedures that you might have to perform before you remove or install the component.

v For a list of supported options for your server, go to http://www.ibm.com/support/.

System reliability guidelines

To help ensure proper cooling and system reliability, make sure that:

v Each of the drive bays has a drive tray installed in it. v There is adequate space around the server to allow the server cooling system to

work properly. Leave approximately 50 mm (2.0 in.) of open space around the front and rear of the server. Do not place objects in front of the fans.

v You have followed the cabling instructions that come with optional adapters. v You have replaced a failed fan within 48 hours.

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices, including your server.

To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

To reduce the possibility of damage from electrostatic discharge, observe the following precautions:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed circuitry. v Do not leave the device where others can handle and damage it.

v While the device is still in its static-protective package, touch it to an unpainted

metal part of the server for at least 2 seconds. This drains static electricity from the package and from your body.

v Remove the device from its package and install it directly into the server without

setting down the device. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device on your server cover or on a metal surface.

v Take additional care when handling devices during cold weather. Heating reduces

indoor humidity and increases static electricity.

Chapter 6. Symptom-to-FRU index

The symptom-to-FRU index lists symptoms, errors, and the possible causes. The most likely cause is listed first. Use this symptom-to-FRU index to help you decide which FRUs to have available when servicing the server.

Notes:

1. Check the configuration before you replace a FRU. Configuration problems can cause false errors and symptoms.

2. For IBM devices not supported by this index, refer to the manual for that device.

3. Always start with “General checkout” on page 17.

4. Some tables have more than two columns; in those instances, more than one column on the left is required to describe the error symptom. Take the action (or replace the FRU) suggested first in the list of the right-hand column, then try the server again to see if the problem has been corrected before taking further action.

5. Always try reseating a suspected component or reconnecting a cable before replacing the component.

The left-hand column of the tables in this index lists error codes or messages, and the right-hand column lists one or more suggested actions or FRUs to replace.

The POST BIOS code displays POST error codes and messages on the screen.

Beep symptoms

Beep symptoms are short tones or a series of short tones separated by pauses (intervals without sound). See the examples in the following table.

Beeps Description 1-2-3

4 Four continuous beeps

Undetermined problems

Use the information in this section if the diagnostic tests did not diagnose the failure, the devices list is incorrect, or the server is inoperative.

Damaged data in CMOS memory or damaged BIOS code can cause undetermined problems. To reset the CMOS data, use the CMOS recovery jumper to override the power-on password and clear the CMOS memory; see “Erasing a lost or forgotten password (clearing CMOS memory)” on page 25. If you suspect that the BIOS code is damaged, see “Updating BIOS code” on page 23.

Check the LEDs on all the power supplies. If the LEDs indicate the power supplies are working correctly, complete the following steps:

1. Turn off the server.

2. Make sure that the server is cabled correctly.

3. Remove or disconnect the following devices (one at a time) until you find the failure (turn on the server and reconfigure each time):

v Any external devices v Surge suppressor device (on the server) v Modem, printer, mouse, or non-IBM devices v Each adapter v Drives v Memory modules (minimum requirement = two 512 MB DIMMs)

Note: Minimum operating requirements are:

a. Power supply b. System board c. One microprocessor d. Memory (with a minimum of two 512 MB DIMMs)

4. Turn on the server. If the problem remains, suspect the following FRUs in the order listed:

v Power supply v System board

Notes:

1. If the problem goes away when you remove an adapter from the system and replacing that adapter does not correct the problem, suspect the system board.

2. If you suspect a networking problem and all the system tests pass, suspect a network cabling problem external to the system.

Problem determination tips

Because of the variety of hardware and software combinations that can be encountered, use the following information to assist you in problem determination. If possible, have this information available when requesting assistance from Service Support and Engineering functions.

v Machine type and model v Microprocessor or hard disk upgrades v Failure symptom

– Do diagnostics fail? – What message appears in the diagnostics log? – What, when, where, single, or multiple servers? – Is the failure repeatable? – Has this configuration ever worked? – If it has been working, what changes were made before it failed? – Is this the original reported failure?

Diagnostics version

– Type and version level

Hardware configuration

– Print (print screen) configuration currently in use – BIOS level

v Operating system software

– Type and version level

To eliminate confusion, identical systems are considered identical only if

Note:

they:

v Are the exact machine type and models v Have the same BIOS level v Have the same adapters/attachments in the same locations v Have the same address jumpers/terminators/cabling v Have the same software versions and levels v Have the same diagnostics code (version) v Have the same configuration options set in the system v Have the same setup for the operation system control files

Comparing

the configuration and software setup between working and non-working

servers will often lead to problem resolution.

Appendix B. Safety information

Note: The service procedures are designed to help you isolate problems. They are

written with the assumption that you have model-specific training on all computers, or that you are familiar with the computers, functions, terminology, and service information provided in this manual.

The following section contains the safety information that you need to be familiar with before servicing an IBM computer.

General safety

Follow these rules to ensure general safety:

v Observe good housekeeping in the area of the machines during and after

maintenance.

v When lifting any heavy object:

1. Ensure you can stand safely without slipping.

2. Distribute the weight of the object equally between your feet.

3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift.

4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the muscles in your back. Do not attempt to lift any objects

that weigh more than 16 kg (35 lb) or objects that you think are too heavy for you.

Do not perform any action that causes hazards to the customer, or that makes

the equipment unsafe.

v Before you start the machine, ensure that other service representatives and the

customer’s personnel are not in a hazardous position.

v Place removed covers and other parts in a safe place, away from all personnel,

while you are servicing the machine.

v Keep your tool case away from walk areas so that other people will not trip over

it.

v Do not wear loose clothing that can be trapped in the moving parts of a machine.

Ensure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it.

v Insert the ends of your necktie or scarf inside clothing or fasten it with a

nonconductive clip, approximately 8 centimeters (3 inches) from the end.

v Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your

clothing.

Remember: Metal objects are good electrical conductors.

v Wear safety glasses when you are: hammering, drilling soldering, cutting wire,

attaching springs, using solvents, or working in any other conditions that might be hazardous to your eyes.

v After service, reinstall all safety shields, guards, labels, and ground wires.

Replace any safety device that is worn or defective.

v Reinstall all covers correctly before returning the machine to the customer.

Electrical safety

CAUTION: Electrical current from power, telephone, and communication cables can be hazardous. To avoid personal injury or equipment damage, disconnect the attached power cords, telecommunication systems, networks, and modems before you open the server covers, unless instructed otherwise in the installation and configuration procedures.

Observe the following rules when working on electrical equipment.

Important: Use only approved tools and test equipment. Some hand tools have

handles covered with a soft material that does not insulate you when working with live electrical currents.

Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock.

v Find the room emergency power-off (EPO) switch, disconnecting switch, or

electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly.

v Do not work alone under hazardous conditions or near equipment that has

hazardous voltages.

v Disconnect all power before:

– Performing a mechanical inspection – Working near power supplies – Removing or installing main units

v Before you start to work on the machine, unplug the power cord. If you cannot

unplug it, ask the customer to power-off the wall box that supplies power to the machine and to lock the wall box in the off position.

v If you need to work on a machine that has exposed electrical circuits, observe

the following precautions: – Ensure that another person, familiar with the power-off controls, is near you.

Remember: Another person must be there to switch off the power, if

necessary.

– Use only one hand when working with powered-on electrical equipment; keep

the other hand in your pocket or behind your back.

Remember: There must be a complete circuit to cause electrical shock. By

observing the above rule, you may prevent a current from passing through your body.

– When using testers, set the controls correctly and use the approved probe

leads and accessories for that tester.

– Stand on suitable rubber mats (obtained locally, if necessary) to insulate you

from grounds such as metal floor strips and machine frames.

Observe the special safety precautions when you work with very high voltages; these instructions are in the safety sections of maintenance information. Use extreme care when measuring high voltages.

84 xSeries 306 Type 1878, 8489 and 8836: Hardware Maintenance Manual and Troubleshooting Guide

v Regularly inspect and maintain your electrical hand tools for safe operational

condition.

v Do not use worn or broken tools and testers. v Never assume that power has been disconnected from a circuit. First, check that

it has been powered-off.

v Always look carefully for possible hazards in your work area. Examples of these

hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds.

v Do not touch live electrical circuits with the reflective surface of a plastic dental

mirror. The surface is conductive; such touching can cause personal injury and machine damage.

v Do not service the following parts with the power on when they are removed from

their normal operating places in a machine: – Power supply units – Pumps – Blowers and fans – Motor generators and similar units. (This practice ensures correct grounding of the units.)

v If an electrical accident occurs:

– Use caution; do not become a victim yourself. – Switch off power. – Send another person to get medical aid.

Safety inspection guide

The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these products. Each machine, as it was designed and built, had required safety items installed to protect users and service personnel from injury. This guide addresses only those items. However, good judgment should be used to identify potential safety hazards due to attachment of non-IBM features or options not covered by this inspection guide.

If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem.

Consider these conditions and the safety hazards they present:

v Electrical hazards, especially primary power (primary voltage on the frame can

cause serious or fatal electrical shock).

v Explosive hazards, such as a damaged CRT face or bulging capacitor v Mechanical hazards, such as loose or missing hardware

The guide consists of a series of steps presented in a checklist. Begin the checks with the power off, and the power cord disconnected.

Checklist:

1. Check exterior covers for damage (loose, broken, or sharp edges).

2. Turn off the computer. Disconnect the power cord.

3. Check the power cord for: a. A third-wire ground connector in good condition. Use a meter to measure

third-wire ground continuity for 0.1 ohm or less between the external ground pin and frame ground.

Appendix B. Safety information 85

b. The power cord should be the appropriate type as specified in the parts

listings.

c. Insulation must not be frayed or worn.

Remove the cover.

5. Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM alterations.

6. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage.

7. Check for worn, frayed, or pinched cables.

8. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

Handling electrostatic discharge-sensitive devices

Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the server, the part, the work mat, and the person handling the part are all at the same charge.

Notes:

1. Use product-specific ESD procedures when they exceed the requirements noted here.

2. Make sure that the ESD-protective devices you use have been certified (ISO

9000) as fully effective.

When handling ESD-sensitive parts:

v Keep the parts in protective packages until they are inserted into the product. v Avoid contact with other people. v Wear a grounded wrist strap against your skin to eliminate static on your body. v Prevent the part from touching your clothing. Most clothing is insulative and

retains a charge even when you are wearing a wrist strap.

v Use the black side of a grounded work mat to provide a static-free work surface.

The mat is especially useful when handling ESD-sensitive devices.

v Select a grounding system, such as those in the following list, to provide

protection that meets the specific service requirement.

Note: The use of a grounding system is desirable but not required to protect

against ESD damage. – Attach the ESD ground clip to any frame ground, ground braid, or green-wire

ground.

– Use an ESD common ground or reference point when working on a

double-insulated or battery-operated system. You can use coax or connector-outside shells on these systems.

– Use the round ground-prong of the AC plug on AC-operated computers.

Grounding requirements

Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.
