Features

The IBM® Netfinity® EXP300 is a compact unit that provides high-capacity, small computer system interface (SCSI) disk storage. It supports up to 14 Ultra160 SCSI drives on a sing le or dual logical bus. It delivers fast, high - volume data transfer, retrieval, and storage functions across multiple drives, to multiple hosts. The expansion enclosure is designed for continuous, reliable service; the modular, redundant disk drives, power supplies with built-in fans, and environmental services monitor (ESM) boards use hot-sw ap tec hnolo gy for easy r e pla cement with out t urni ng off the expansion unit.

The expansion unit supports Ultra160 SC SI for the host an d drive interfaces and it is designed for easy installation and integration into a variety of system environments.

The following table summarizes the features of the expansion unit. For a list of the operating spe cifications, suc h as weight, height, and heat output, see “Operating

specifications” on page 5.

Clustering support

Clustering is a feature of the expansion unit. Clustering is a means of sharing SCSI buses and disk drives among SCSI controllers to provide redundancy of SCSI controllers and servers. This redundancy is important if a hardware component fails. If a hardw a re component fails after clust e ring has been set up, another server will take ownership of the disk drives or SCSI b u s.

The IBM Netfinity EXP300 supports twin-tailed clustering. With twin-tailed clustering, you can connect two IBM ServeRAID

unit. In the twin-tailed clustering environment, you can use dual-host controllers cabled separately to the EXP300 expansion unit; however, only a single logical bus of 13 drives is supported. Each SCSI device on a SCSI bus must have a unique ID. To prevent conflicts in a twin-tailed configuration, do not install a drive in the bay that uses SCSI ID 6 because your secondary SCSI Serv eRAID controller is set to 6.

Service tip: If you use IBM ServeRAID controllers in a cluster configuration, the termination power LED on the back of the expansion unit is useful. The ServeRAID controller provides the signal for termination power. If the termination power LED is not lit, it indicates that a particular EXP300 expansion unit is not attached to a controller that is turned on. Make a note of which EXP300 expansion unit is attached to which se r v er before the hard w a re is serviced .

Cluste ring requires add itional hardw a re an d spe cialized so f tw a re . For mo re informat ion, visit the IBM Netfinity Cluster Solu tions Web site at:

Additional Service Information

Turning the expansion unit on and off

This section contains instructions for turning the expansion unit on and off under normal and emergency circumstances.

If you are turning on the expansion unit after an emergency shutdown or power outage, refer to “Turning on the expansion unit after an emergency” on page 5.

Turning on the expansion unit

Use this procedure to turn on the power for the initial startup of the expansion unit.

1. Verify that: a. All cables are properly attached.

b. Both power cords are plugged into the back of the expansion unit and into

properly grounded electrical out lets.

c. All hard disk drives are locked securely in place.

d. All switch es are set correctly: the internal option swit ches 1 through 4,

Netfinity EXP300 Type 3531 3

2. Check the system documentation for all the hardware devices you intend to turn on and determine the proper power-on sequence.

Note: Be sure to turn on the IBM Netfi nity EXP300 expansion unit before or at

the same time as you turn on the server.

3. Turn on each device, based on this powe r-on sequence.

4. Turn on both power supplies on the back of the unit. The expansion unit might tak e a few seconds to turn on. During this time, you

might see the fault (amber) and the power (green) LEDs on the expansion unit turn on and off intermittently. When the power-on sequence is complete, only the power (green) LEDs on the front and back should remain on. If one or more fault (amber) LEDs remain lit, refer to “Symptom-to-FRU index” on page 7.

Attention: If you have data stored on the drives, label the drives before you remove them. Then, when you replace the drives, install each one in the same drive bay from which you removed it. Failure to do so will result in a loss of data.

Turning off the expansion unit

Attention: Except in an emergency situation, never turn off the power if any fault LEDs are lit on th e expan sion unit . Cor rec t th e fau lt be for e you att e mpt to turn of f the power, using the proper troubleshooting or servicing procedure. This will ensure that the expansion unit will turn on correctly later. Refer to “Symptom-to-FRU index” on page 7.

Statement 5

CAUTION: The power control button on the device and the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.

2 1

The expansion unit is designed to run contin uou sly, 24 hours a day. Turn off the power only when at least one of the following is true:

• Instructions in a hardware or software procedure require you to turn off the power.

• A ser vi c e te chnician tells you to tu rn off the power.

• A power outage or emergency situation occurs (see “Turning off the expansion unit in an emergency” on page 5).

Use the following procedure to turn off the expansion unit:

1. Power down the server attached to the expansion unit.

4 IBM Netfinity EXP300 - Type 3531 Hardware Maintenance Manual

2. Make sure that all amber fault LEDs are off. If any fault LEDs are lit (drives, power suppl ies, or ESM boards), correct the p roblem before you turn off the power. For guidance, refer to “Symptom-to-FRU index” on page 7.

3. Turn off both power supplies.

Turning off the expansion unit in an emergency

Attention: Emergency situations might include fire, flood, extre me we ather conditions, or other hazardous circumstances. If a power outage or emergency situation occurs, always turn off all power switches on all computing equipment. This will help safeguard your equipment from potential damage due to electrical surges when power is restored. If the expansion unit loses power unexpectedly, it might be due to a hardware failure in the power sy stem or midplane (see “Symptomto-FRU index” on page 7).

Use the following procedure to turn off the expansion unit during an emergency situation:

1. Power down the server attached to the expansion unit.

2. If you have tim e, st op al l act ivi ty an d chec k the LEDs ( fr ont and back ). Make n ote of any fault LEDs that are lit so that you can corr e ct the problem when you turn on the power again.

3. Turn off all power supplies; then, unplug the power cables from the expansion unit.

Turning on the expansion unit after an emergency

Use the following procedure to restart the expansion unit if you turned off the power supplies during an emergency shutdown, or if a power failure or a power outage occurred:

1. After the emergency situation is over or power is restored, check the expansion unit for damage. If there is no visible damage, continue with Step 2; otherwise, consult with customer to repair the unit .

2. After you have checked for damage, plug in the expansion-unit power cables and turn on the power switches.

3. Check the syst em docu mentat i on for the har dwa r e devi ces y ou in tend t o turn on, and determine the proper power-on sequence.

Note: Be sure to turn on the IBM Netfinity EXP300 before or at the same time

you turn on the sy ste m unit.

4. Turn on each device, based on the power-on sequence.

5. Turn on both power supplies on the back of the IBM Netfini ty EX P 300.

6. Only the po we r ( green) LEDs on the front and back shou ld be on. If one or more of the fault (amber) LEDs are on , refer to “Sympt om- to-FRU index” on pa ge 7 for instructions.

7. Use your installed software application as appropriate to check the status of the expansion unit.

Locati ons

Getting started

You can insta ll the EXP300 expansion unit in the followi ng types of enclosures:

• An Electronic Industries Association (EIA) 310 standard rack cabinet

• The IBM Netfinity EXP300 Rack-to-Tower Conversion Kit

• An IBM Netfinity NetBAY enclosure

8 IBM Netfinity EXP300 - Type 3531 Hardware Maintenance Manual

You will need a flat-blade screwdriver and a Phillips-head screwdriver to install your expansion unit. Each type of enclosure comes with general installation instructions for installing optional dev ices .

Before you begin, revi e w th e following assum p tions:

• If you are installing the expansion unit in a rack, you have already installed the other components in the rack and moved the rack t o its permanent operating location.

• Y ou have already installed and configured the host controllers and appropriate host adapters.

• There are 68-pin VHDCI SCSI cables attached to the host controllers, ready for final connection to the expansion unit.

• The installation site meet s al l area, environmental, power, and site requirements for the expansion unit. Refer to the expansion unit requirements listed under “Operating specifications” on page 5.

Preparing the expansion unit

This sec tion e xplain s how to r emove th e CRUs an d set t he int erfac e opt ion s to pr e par e the expansion unit for installation.

Removing CRUs

It is easier to lift the expansion unit and install it in a rack or tower enclosure if you remove all CRUs (disk drives, po wer supplie s, an d ESMs ) first. A fully loaded expansion unit with 14 disk drives and two power supplies with built-in fans installed weighs 36.1 kg (79.5 lb). The standard unit with two power supplies weighs

22.5 kg (49.5 lb). If you remove all the CRUs, you can reduce the overall weight.

Attention: If you have data stored on the drives, label the drives before you remove them. Then, when you replace the drives, install each one in the same drive bay from which you removed it.

See “Locations” on page 8 for information on removing the CRUs.

Statement 4

≥18 kg (37 lbs) ≥32 kg (70.5 lbs) ≥55 kg (121.2 lbs)

CAUTION: Use safe practices when lifting.

Netfinity EXP300 Type 3531 9

Setting the interface options and ID settings

1 2 3 4

Internal

options switches

When you install a drive CRU in the expan sion unit , the drive tr ay plugs into a printed circuit board called the midplane. The midplane sets the SCSI bus number and ID automatically.

The switc h card located on the b a ck of the expansion unit has five external option switches, four internal option switches, and a unit ID switch. It is e a sier to set these switches before you install the expansion unit in a rack or tower enclosure.

Attention: Always set the option switches while the expansion unit and host server are turned off. Failure to do so will result in loss of data.

External option switches

Unit ID switch

External option switches

The five opt ion switches on the exterior of the switch card are: Option switch 1 controls the power supply to the expansion unit. Option switches 2 through 5 are reserved; leave these switches in the default positions.

Option switch 1 — Power-control switch

When this opti on switch is set to Off, the expansi on unit turns on and off automatically when you turn the host machine on and off. This occurs only if termination power is present (the termination-power LED is on) at the external SCSI connector.

When this option switch is se t to On (the default), you must turn the expansion unit on and off separately.

Option switches 2 through 5 — Reserved

These opti on switches are reserved; leave these option switches set to the default positions. Set switches 2 through 5 (On , On , Off, Off) respectively.

Internal option switches

The four option switches ins ide the switch card are: Option swi tch 1 controls SCSI addresses for the rack and tower installation modes. Option switch 2 controls the fron t p anel power and fault LEDs for the rack and tower. Option switch 3 controls the SCSI bus, and option switch 4 is reserved; leave this switch in the Off position.

Attention: A loss of data can occur if y ou change the position of inte rnal option

switch 1 or interna l option swi t ch 3 af te r sto ring data on the drive s. Ref e r to

“Conversion of EX P 300 to a tower or from a tower” on page 25 if you want to chan ge the configuration of your expansion unit from a rack (internal switch 1 Off) to a tower (internal switch 1 On) or from a tower to a rack orientation.

SCSI buses and IDs

There are two SCSI buses (bus 1 and bus 2) in the expansion unit. Each bus uses seven SCSI ID numbers. Each disk drive within the expansion un i t has a unique SCSI bus an d ID assignment, based on its physical locati on in the expan s ion unit and the setting of op t ion switch 1 (inside the switch card) .

Option switch 1 — SCSI-address switch

This switc h sets the order of the SCSI IDs. The default is Off for a rack unit installation. In the rack unit, the SCSI IDs are from left to right, 0, 1, 2, 3, 4, 5, 6, 8, 9, 10, 11, 12, 13, and 14. When this switch is set to On for a tower installati on , the SCSI IDs are from top to bottom, 0, 1, 2, 3, 4, 5, 6, 8, 9, 10, 11, 12, 13, and 14.

I f t he data shown on the View Configurat ion screen begins with 0, it denotes SCSI IDs. If the data shown on the View Conf iguration screen begins with 1, it denotes bay numbers.

Netfinity EXP300 bays

The following sections describe the hot-swap CRUs, the switch card bay, and the bridge card bay on the Netfinity EXP300 expansion unit.

Wi th the hot-swap feat ures of the Netfin ity EXP300, you can remove an d replace hard disk dri ves, power supplies/fans, and ESM boards without turning off the expansion unit. Therefore, you can maintain the availability of your system while a hot-swap device is removed, installe d , or replaced .

Hot-swap drive bays

The following illustration shows the location of the hot-swap drive bays accessible from the front of your expansion unit. The Netfinity EXP300 supports up to 14 IBM Ultra160 SCSI or Ultra2 SCSI hard disk drives. These drives come pre installed in a drive tray. The drive and tray assembly is called a drive CRU (customer replaceable unit). You can install the drive CRUs in the 14 drive bays on the front of the expansion unit.

In the following figure, seven of the 14 bays contain drive CRUs, and seven bays contain filler panels. To maintain proper cooling within your expansion unit, always keep a filler panel in each drive bay that does not contain a drive CRU. For information on installing and replacing drive CRUs, refer to “Working wit h hot-swap

drives” on page 17.

Hot-swap drive bays

Hot-swap ESM bays

These are the locations of the environmental services monitor (ESM) boards. The ESM boards provide a SCSI interface to the drives and monitor the overall status of the expansion unit. The ESM boards are hot-swappable. Refer to “Replacing an ESM board ” on page 24 for step-by-step instructions.

Hot-swap power supply/fan bays

Your expansion unit comes with two 500 Watt hot-swap and redundant power supplies with built-in fans. The power supplies are redundant in that a single power supply can provide adequate power and cooling for the entire expansion unit. A single power supply can support up to 14 disk drives; however, both power supplies must be install ed , even if one power supply is not operational. Refer to “Working with hot-swap power” on page 21 for step-by-step instructions.

Switch card bay

Your ex p a n s ion unit come s wi t h a swi t ch card that cont a i ns five e xt e rna l o p tion switch e s an d fo u r int ernal option s wi t ches. The swit ch ca rd is lo ca t ed on the back of the expansion unit between the two power supplies. The switch card contains switches that control how pow er is sup plied to the e xpans io n unit and wh at expansion unit services are enabled (fo r example , switchi ng between a tower configuration and a rack configur atio n or switching be twee n a single bus and a dualbus configuration.) In a dual-bus configuration, each bus uses seven drives. A singlebus configuration uses all 14 drives. To access the four internal option switches, you must turn off the expansion uni t; then r emove the switch car d. Refer to “Replacing the switch card” on page 23 for step-by-step instructions.

Attention: Never remove the switch card or change the switch card settings while the expansion unit and host server is turned on. Refer to “Turning the expansion unit on and off” on pa g e 3.

In addition to the internal and external option switches, the switch car d also has a 10position unit ID switch for setting the expansion unit ID using values 0 through 9.

• Ensure that your current system configuration is working properly.

• Back up all important data before you make changes to storage devices, such as hard disk drives.

This section explains how you can increase the expansion unit capacity by adding more drives or replacing existing drives with larger capacity drives.

Before you install or remove drive CRUs, review the following information:

Hot-swap hardware

You can replace a failed hard disk drive without turning off the expansion unit. Therefore, you can continue to operate your system while a hard disk drive is removed or installed. These drives are known as hot-swap drives.

Drive CRUs Y our expans i on unit suppor ts IBM Ultra160 and IBM Ultra2 SCSI hard

disk drives. These IBM drives come pre-installed in a drive tray, ready for installation. (Do not detach th e drive from the tray.) This drive and tray assembly is called a drive customer replaceable unit (CRU). You can install the drive CRUs directly into the 14 drive bays on the front of the expansion unit.

Be sure to record the location information for each drive before you remove it. Ensure that you keep track of the drives and their corresponding bays.

Netfinity EXP300 Type 3531 17

Attention: If you re-install a drive in the wrong bay, you could lose data.

Drive LEDs Each drive bezel has two LEDs, whic h i n dicate the st a tus for tha t

particular drive. The drive LED states and descriptions are as follows:

LED LED State Description

Activity LED Green/flashing Flashes during

Installing the EXP300 in a rack

The EXP300 expansion unit requires 3U (5.25 in) of Electronic Industries Association (EIA) rack-mounting space.

Important : Review the documentation that comes with your rack enclosure f or safety and cabling considerations. When installing your server in a rack, the following considerations should be made:

• Install the expansion unit in a maximum 35 degree C environment.

• To ensure proper air flow, do not block the air vents; usually 15 cm (6 inches) of

air space is sufficient. Note: Because of the limited space in some racks, it might be easier to connect

and route cables befor e you install the mounting brackets and hardware devices.

• To ensure stability, take precautions to prevent uneve n loadi ng of the rack.

Loading of the rack should begin at the bottom.

• Turn off the power to your rack.

• When multiple components are installed in a rack, take prec auti ons to prev en t

overloading of the power outlets.

• The expansi on unit should always be con nected to a properly grounded outlet.

• Refer to the rack docu mentat i on for inst r uct io ns on re movi ng the rac k encl os ur e

doors and sid e panels.

Use the rack-mounting template that comes with the expansion unit to locate the rackmounting holes and install the unit in a rack cabinet. If you do not have the template, you can use the following steps to install your expansion unit:

1. Use the following illustration of the front and rear rack mounting flanges to determine the appropriate rack-m o unting ho les for insta lling cage nut s or clip nuts to s e cu re the Netfinity EXP300 rails. From l e ft to right, the illustration shows the front and rear flanges respectively.

Chapter 2. Related service information

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

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

Safety information

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

General saf et y

Follow these rules to ensure general safety:

• Observe good housekeeping in the area of the machines during and after maintenance.

• When lifting any heavy object:

1. Ensure you can stand safely without slipping.

2. Distribute the weight of th e o b je ct 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 wi th your leg muscles; this action remov e s the strain from the muscles in your back . Do not attempt to lift any

objects that weigh more than 16 kg (35 lb) or obj ects that you think ar e too heavy for you.

• Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe.

• Before you start the machine, ensure that other service repr esentatives and the customer's personnel are not in a hazardous position.

• Place removed covers and other parts in a safe place, away from all personnel, while you are servicing the machine.

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

• Do not wear loose cloth ing that can be trapped in the moving par ts of a machine. Ensure that your sleeves are fastened or rolled up above your elb ows. If your hair is long, fasten it.

• Insert the ends of your necktie or scarf inside clothing or fasten i t with a nonconductive clip, approximately 8 centimeters (3 inches) from the end.

• Do not wear jewelry, chains, metal-frame eyeg lasses, or meta l fasteners for your clothin g .

Remember: Metal objects are good electrical conductors.

• Wea r safety glasses when you are: hammering, drilling soldering, cutting wire, attachi ng springs, using solvents, or work ing in any other con ditions that mig ht be hazardous to your eyes.

• After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective.

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

Electrical safety

CAUTION: Electrical c urrent from power, telephone, and co mmunication cables can be hazardous. To avoid personal injury or equ ipment damage, dis connect th e attac hed power cor d s, te lec o mm unication sy ste m s, net w o rk s, and modems befo re y ou o pe n 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

• Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an el ectri cal accident occurs, you can then operate the switch or unplug the power cord quickly.

• Do not work alone under hazardous conditions or near equipment that has hazardous voltages.

• Disconnect all power before: — Performing a mechanical inspection — Working near power supplies — Remov ing or installing main units

• 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 machin e and to lock the wall box in the off position.

• If you need to work on a machine that has e xposed electri cal cir cuits, observe the following precautions:

— Ensure that another person, familiar with the power-off controls, is near

you. Remember: Another per son must be there to switch off the power, if

necessary.

— Use only one hand when working with powered-on electri cal equipment;

keep the other hand in your pocket or behind your back. Remember: There must be a co mplete circ ui t to ca u s e ele ct r i ca l 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 te ster.

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

from grounds such as metal floor strips and machine frames.

handles covered with a s of t 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 ty p e of mat to protect yours e lf from electrical shock.

42 IBM Netfinity EXP300 - Type 3531 Hardware Maintenance Manual

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.

• Regularly inspect and maintain your electrical hand tools for safe operational condition.

• Do not use worn or broken tools and testers.

• Neve r assume that power has b e en disconnected from a cir cu it. First, check that it has been po we red-off.

• Always look car efully for pos sible hazard s in your work ar ea. Examples of th ese hazards are moist floors, nongrounded power extension cables, power surges, and mi ss i ng sa f e t y gro u nds.

• Do not touch live electrical circuits with the reflective sur f ace of a plastic dental mirror. The surfac e is conductive ; such touch in g ca n ca u s e per sonal injury a nd machine damage.

• Do not service the following parts with the power on when they ar e removed from their normal operating places in a machine:

— Power supply units —Pumps —Blowers and fans — Motor generators

and simil a r units. (This practice ensures c orrect grounding of the units.)

• If an electrical accide nt occ urs: — 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 s afety items installed to prot ect users a nd service perso nnel fr om injury. This guide addresses only those items. However, good judgment should be used to identify pot enti al sa fe ty haza r ds d ue to att ach ment of n on-I BM features or option s no t 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 f irst corre cting the proble m.

Consider these conditions and the safety hazards they present:

• Electrical hazards, especiall y primary power (primary voltage on the frame can cause serious or fatal electr ical shock).

• Explosive hazards, such as a damaged CRT face or bulging capacitor

• Mechanical hazards, such as loose or missing hardwar e

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:

Chapter 2. Related service information 43

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

2. Power-off the computer. Disconnect the power cord.

3. Check the power cord for: a. A third- wire groun d connector in good con di tion. Use a meter to measure

thir d-wire ground continuity for 0.1 ohm or less between t he external ground pin and frame ground.

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

listings.

c. Insulation must not be frayed or worn.

4. 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 obv ious unsafe cond itions , su ch 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-supp ly cover fastener s ( screws or rive ts) 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 machine, 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 requir ements 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:

• Keep the parts in protective packages until they are inserted into the product.

• Avoid contact with other people.

• Wear a grounded wrist strap against your skin to eliminate static on your body.

• Prevent the part from touching your clothing. Most clothin g is insulative and retains a charge even when you are wearing a wrist strap.

• Use the black side of a grounded work mat to provide a static-fr ee work surfac e. The mat is especially useful when handling ESD-sensitive devices.

• Select a grounding system, such as those l isted below, 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 connectoroutside shel ls on these systems.

44 IBM Netfinity EXP300 - Type 3531 Hardware Maintenance Manual

— Use the round ground-prong of the ac plug on ac-operated computers.

Grounding require m ents

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

Problem determination tips

Due to the variety of hardware and software combin ations that can be encou ntered, use the following information to assist you in problem determination. If possible, have this informati on available when requesting assistance from Service Support and Engineering functions.

80 IBM Netfinity EXP300 - Type 3531 Hardware Maintenance Manual

• Machine type and model

• Processor or hard disk upgrades

• Failure symptom — Do diagnostics fail? — What, when, where, single, or multiple systems? — Is the failure repeatable? — Has this configuration ever worked? — If it has been working, what changes were made prior to it failing? — Is this the original reported failure?

• Reference/Diagnostics version — Type and version level

• Hardware configuration — Print (print screen) configuration currently in use —BIOS level

• Operati ng sy stem software — Type and version level

Note: To eliminate confusion, identical systems are considered identical only if

they:

1. Are the exact machine type and models

2. Have the same BIOS level

3. Have the same ad ap te rs/attachments in the same location s

4. Have the same ad dress jumpers/terminators/cabl ing

5. Have th e same software versions and levels

6. Have the same Refe rence/Diagnostics Diskette (version)

7. Have the same configuration opt ions set in the system

8. Have the same se tup for the operation system control files

Comparing the configuration and software se t- up between "working and non-working" systems will often lead to problem resolution.
