Important information about replacing 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 hardware
maintenance manual or direct substitutions for those FRUs can be used.
Products marketed before June 2006 Products marketed after June 2006

2Hardware Maintenance Manual

Chapter 2. Safety information
This chapter contains the safety information that you need to be familiar with
before servicing a computer.
General safety
Follow these rules to ensure general safety:
vObserve good housekeeping in the area of the machines during and after
maintenance.
vWhen 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.
vDo not perform any action that causes hazards to the customer, or that makes
the equipment unsafe.
vBefore you start the machine, ensure that other service representatives and the
customer’s personnel are not in a hazardous position.
vPlace removed covers and other parts in a safe place, away from all personnel,
while you are servicing the machine.
vKeep your tool case away from walk areas so that other people will not trip over
it.
vDo 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.
vInsert the ends of your necktie or scarf inside clothing or fasten it with a
nonconductive clip, approximately 8 centimeters (3 inches) from the end.
vDo not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your
clothing.
Remember: Metal objects are good electrical conductors.
vWear 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.
vAfter service, reinstall all safety shields, guards, labels, and ground wires.
Replace any safety device that is worn or defective.
vReinstall all covers correctly before returning the machine to the customer.
Electrical safety
© Lenovo 2005, 2008. Portions © IBM Corp. 2005. 3

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.
vFind 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.
vDo not work alone under hazardous conditions or near equipment that has
hazardous voltages.
vDisconnect all power before:
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing Field Replaceable Units
vBefore 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.
vIf 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.
vRegularly inspect and maintain your electrical hand tools for safe operational
condition.
vDo not use worn or broken tools and testers.
vNever assume that power has been disconnected from a circuit. First, check that it
has been powered-off.
4Hardware Maintenance Manual

vAlways 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.
vDo 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.
vDo 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.)
vIf 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:
vIf 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.
vIf 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.
If you are not sure of the voltage provided at your electrical outlet, contact your
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:
vElectrical hazards, especially primary power (primary voltage on the frame can
cause serious or fatal electrical shock).
vExplosive hazards, such as a damaged CRT face or bulging capacitor
vMechanical 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.
4. 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:
vKeep the parts in protective packages until they are inserted into the product.
vAvoid contact with other people while handling the part.
vWear a grounded wrist strap against your skin to eliminate static on your body.
6Hardware Maintenance Manual

vPrevent the part from touching your clothing. Most clothing is insulative and
retains a charge even when you are wearing a wrist strap.
vUse 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.
vSelect 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.
