Important information about replacing the RoHS compliant FRUs

RoHS, the Restriction of Hazardous Substances in Electrical and Electronic Equipment Directive (2002/95/EC) is a European Union legal requirement affecting the global electronics industry. RoHS requirements must be implemented on Lenovo products placed on the market and sold in the European Union after June 2006. Products on the market before June 2006 are not required to have RoHS compliant parts. If the parts are not compliant originally, replacement parts can also be noncompliant, but in all cases, if the parts are compliant, the replacement parts must also be compliant.

Note: RoHS and non-RoHS FRU part numbers with the same fit and function are

identified with unique FRU part numbers.

Lenovo plans to transition to RoHS compliance well before the implementation date and expects its suppliers to be ready to support Lenovo’s requirements and schedule in the EU. Products sold in 2005, will contain some RoHS compliant FRUs. The following statement pertains to these products and any product Lenovo produces containing RoHS compliant parts.

RoHS compliant ThinkCentre parts have unique FRU part numbers. Before or after June, 2006, failed RoHS compliant parts must always be replaced using RoHS compliant FRUs, so only the FRUs identified as compliant in the system HMM or direct substitutions for those FRUs can be used.

Products marketed before June 2006 Products marketed after June 2006 Current or original

part

Non-RoHS Can be Non-RoHS Must be RoHS Must be RoHS Non-RoHS Can be RoHS Non-RoHS Can sub to RoHS RoHS Must be RoHS

Replacement FRU Current or original

Note: A direct substitution is a part with a different FRU part number that is

automatically shipped by the distribution center at the time of order.

2 Hardware Maintenance Manual

Chapter 2. Safety information

This chapter contains the safety information that you need to read and understand before servicing a 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/workstation 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 Field Replaceable 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 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.

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.

4 Hardware Maintenance Manual

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

similar units. (This practice ensures correct grounding of the units.)

and

v If an electrical accident occurs:

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

Voltage-selection switch

Some computers are equipped with a voltage-selection switch located near the power-cord connection point on the computer. If your computer has a voltage-selection switch, ensure that you set the switch to match the voltage available at your electrical outlet. Setting the voltage-selection switch incorrectly can cause permanent damage to the computer.

If your computer does not have a voltage-selection switch, your computer is designed to operate only at the voltage provided in the country or region where the computer was originally purchased.

If you relocate your computer to another country, be aware of the following: v If your computer does not have a voltage-selection switch, do not connect the

computer to an electrical outlet until you have verified that the voltage provided is the same as it was in the country or region where the computer was originally purchased.

v If your computer has a voltage-selection switch, do not connect the computer to

an electrical outlet until you have verified that the voltage-selection switch is set to match the voltage provided in that country or region.

you are not sure of the voltage provided at your electrical outlet, contact your

If local electric company or refer to official Web sites or other literature for travelers to the country or region where you are located.

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 features or options not covered by this inspection guide.

Chapter 2. Safety information 5

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. Power-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.

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 alterations. Use good judgment as to the safety of any

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 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 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 while handling the part. v Wear a grounded wrist strap against your skin to eliminate static on your body.

6 Hardware Maintenance Manual

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 listed 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 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.
