Strategy for replacing FRUs for CTO, CMV, and GAV products
Product definition
Dynamic Configure To Order (CTO)
This provides the ability for a customer to configure a Lenovo solution
from an eSite, and have this configuration sent to fulfillment, where it is
built and shipped directly to the customer. The machine label, PC
Entitlement Warehouse (PEW), eSupport, and the HMM will include these
products as the 4-digit machine type (MT) and 3-digit model, where model
= ’CTO’ (Example: 8129-CTO).
Custom Model Variant (CMV)
This is a unique configuration that has been negotiated between Lenovo
and the customer. A unique 4-digit MT and 3-digit model is provided to
the customer to place orders (Example: 8129-W15). A CMV is a special bid
offering. Therefore, it is NOT generally announced.
v The machinetypemodel(MTM)portionofthemachinelabelisthe
4-digit MT and 3-digit model, where model = ’CTO’ (Example:
8129-CTO). The PRODUCT ID portion of the machine label is the 4-digit
MT and 3-digit CMV model (Example: 8129-W15).
v The PEWrecordisthe4-digitMTand3-digitmodel,wheremodel=
’CTO’ (Example: 8129-CTO).
v eSupport willshowboththeCTOandCMVmachinetypemodels
(Example: 8129-CTO and 8129-W15 will be found on the eSupport site.)
v The HMMwillhavethe4-digitMTand3-digitCTOmodelonly
(Example: 8129-CTO). Again, CMVs are custom models and are not
found in the HMM.
General
AnnounceVariant (GAV)
This is a standard model (fixed configuration). GAVs are announced and
offered to all customers. The MTM portion of the machine label is a 4-digit
MT and 3-digit model, where model = a “fixed model number”, not ’CTO’
(Example: 8129-F1U). Also, PEW, eSupport, and the HMM will list these
products under the same fixed model number.
FRU Identification for CTO, CMV, and GAV products
There are three information resources to identify which FRUs are used to support
CTO, CMV, and GAV products. These sources are PEW, eSupport, and the HMM.
Using PEW
vPEW is theprimarysourceforidentifyingFRUpartnumbersandFRU
descriptions for the key commodities for CTO, CMV and GAV products at a MT

system boards, microprocessors, Liquid Crystal Displays (LCDs), and memory.
v Remember, AllCTOandCMVproductsareloadedinPEWunderthe4-digit
MT and 3-digit model, where model = ’CTO’ (Example: 8129-CTO). GAVs are
loaded in PEW under the 4-digit MT and 3-digit model, where model = a “fixed
model number”, not ’CTO’ (Example: 8129-F1U).

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 after June 2006. Products
on the market before June 2006 are not required to have RoHS compliant parts.
Chapter 1. About this manual 3
So, 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.
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. 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.

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 onlyapprovedtoolsandtestequipment.Somehandtoolshave
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 theroomemergencypower-off(EPO)switch,disconnectingswitch,or
electrical outlet. If an electrical accident occurs, you can then operate the switch
or unplug the power cord quickly.
v Do notworkaloneunderhazardousconditionsornearequipmentthathas
hazardous voltages.
v Disconnect allpowerbefore:
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing main units
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 youneedtoworkonamachinethathasexposedelectricalcircuits,observe
the following precautions:
– Ensure that another person, familiar with the power-off controls, is near you.
Remember: Another personmustbetheretoswitchoffthepower,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 mustbeacompletecircuittocauseelectricalshock.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 inspectandmaintainyourelectricalhandtoolsforsafeoperational
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.
6 HardwareMaintenanceManual
v Always lookcarefullyforpossiblehazardsinyourworkarea.Examplesofthese
hazards are moist floors, nongrounded power extension cables, power surges,
and missing safety grounds.
v Do nottouchliveelectricalcircuitswiththereflectivesurfaceofaplasticdental
mirror. The surface is conductive; such touching can cause personal injury and
machine damage.
v Do notservicethefollowingpartswiththepoweronwhentheyareremoved
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 anelectricalaccidentoccurs:
– 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 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,especiallyprimarypower(primaryvoltageontheframecan
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.
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.
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 theblacksideofagroundedworkmattoprovideastatic-freeworksurface.
The mat is especially useful when handling ESD-sensitive devices.
v Select agroundingsystem,suchasthoselistedbelow,toprovideprotectionthat
meets the specific service requirement.
Note: The useofagroundingsystemisdesirablebutnotrequiredtoprotect
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.
