Important safety information
General safety
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
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.
Attention: 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. · Before you start the machine, ensure that other service
representatives 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 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. · 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. · Do not wear jewelry, chains, metal-frame eyeglasses, or metal
fasteners for your clothing. Remember: Metal objects are good electrical
conductors. · 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. · 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.
CAUTION:
Keep fingers and other parts of your body away from hazardous, moving parts.
If you suffer an injury, seek medical care immediately.
CAUTION:
Avoid contact with hot components inside the computer. During operation, some
components become hot enough to burn the skin. Before you open the computer
cover, turn off the computer, disconnect power, and wait approximately 10
minutes for the components to cool.

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 computer 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.
· 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.
· 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 Removing
or installing Field Replaceable Units (FRUs) · 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. · 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 a tester, 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. · Regularly inspect and maintain
your electrical hand tools for safe operational condition. · Do not use worn
or broken tools and testers. · Never assume that power has been disconnected
from a circuit. First, check that it has been powered-off. · 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. · 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. · Do not service the
following parts with the power on when they are removed from their normal
operating places in a machine:
2 P2 Tower Hardware Maintenance Manual
Power supply units Pumps Blowers and fans Motor generators and similar
units. (This practice ensures correct grounding of the units.) · 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 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: · Electrical
hazards, especially primary power (primary voltage on the frame can cause
serious or fatal
electrical shock). · Explosive hazards, such as a damaged CRT face or bulging
capacitor · 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. 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.
Chapter 1. Important safety information 3
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: · Keep the parts in protective packages
until they are inserted into the product. · Avoid contact with other people
while handling the part. · Wear a grounded wrist strap against your skin to
eliminate static on your body. · Prevent the part from touching your clothing.
Most clothing 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-free work surface. The mat is especially
useful when handling ESD-sensitive devices. · 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.

Important service information
Strategy for replacing FRUs
Before replacing parts: Ensure that all software fixes, drivers, and UEFI BIOS
downloads are installed before you replace any FRUs listed in this manual.
After a system board is replaced, ensure that the latest UEFI BIOS is loaded
to the system board before you complete the service action.
To download and install software fixes, drivers, and UEFI BIOS, go to
https://pcsupport.lenovo.com and follow the instructions on the screen.
Use the following strategy to prevent unnecessary expense for replacing and
servicing FRUs: · If you are instructed to replace a FRU but the replacement
does not correct the problem, reinstall the
original FRU before you continue. · Some computers have both a processor board
and a system board. If you are instructed to replace either
the processor board or the system board, and replacing one of them does not
correct the problem, reinstall that board, and then replace the other one. ·
If an adapter or a device consists of more than one FRU, any of the FRUs might
be the cause of the error. Before replacing the adapter or device, remove the
FRUs, one by one, to see if the symptoms change. Replace only the FRU that
changed the symptoms.
Strategy for replacing a hard disk drive or a solid-state drive
Always try to run a low-level format operation before replacing a hard disk
drive or a solid-state drive. This will cause all customer data on the drive
to be lost. Ensure that the customer has a current backup of the data before
you perform this task.
Attention: The drive startup sequence in the computer you are servicing might
have been changed. Be extremely careful during write operations such as
copying, saving, or formatting. If you select an incorrect drive, data or
programs can be overwritten.
Important notice for replacing a system board
Some components mounted on a system board are very sensitive. Improper
handling of a system board can cause damage to those components, and may cause
a system malfunction.
After replacing the system board, use the Golden Key U1 tool to bind the model
type, serial number, and Brand ID of the computer with the new system board.
Refer to https://support.lenovo.com/us/en/solutions/ ht102004 for
instructions.
Attention: When handling a system board: · Do not drop a system board or apply
any excessive force to it. · Avoid rough handling of any kind. · Avoid bending
a system board and hard pushing to prevent cracking at each Ball Grid Array
(BGA)
chipset.

How to use error codes
Use the error codes displayed on the screen to diagnose failures. If more than
one error code is displayed, begin the diagnosis with the first error code.
Whatever causes the first error code might also cause false error codes. If no
error code is displayed, see whether the error symptom is listed in the
“Symptom-to-FRU Index” section.
Strategy for replacing FRUs for CTO, special-bid, and standard models
This topic provides information about the model types and FRU identification.
Product definition
This topic introduces different model types and how to identify each type.
Dynamic Configure To Order (CTO) model This model provides the ability for a
customer to configure a Lenovo solution from a Web site, and have this
configuration sent to fulfillment, where it is built and shipped directly to
the customer. The machine label and eSupport will load these products as the
4-character MT, 4-character model, and 2-character country code. The model is
“CTO1” and the default country code is “WW” (example: 20AACTO1WW). Special-bid
model This model is a unique configuration that has been negotiated between
Lenovo and the customer. A unique MTM consists of a 4-character MT, a
4-character model, and a numeric 2-character country code is provided to the
customer to place orders (example: 20AA000955). The country code assigned is
numeric and does not designate a specific country or region. The custom model
factsheet for the MTM indicates which country the special-bid MTM is set up
for. Special-bid offering is not generally announced. Standard model Standard
models (fixed configuration) are announced and offered to all customers. The
MTM portion of the machine label consists of a 4-character MT, a 4-character
model, and an alphabetic 2-character country code. The country code assigned
is alphabetic and represents a designated country or region (example:
20AA0009UK).
FRU identification
To identify FRUs for a product, do the following: 1. Go to:
https://support.lenovo.com/partslookup 2. Type the Machine Type in the
corresponding field to get a general FRU list, or type the Serial Number for
more detailed FRU information.

Service checkout and symptom-to-FRU index
This chapter provides information about general service checkout and symptom-
to-FRU index.
Service checkout
Attention: The drives in the computer you are servicing might have been
rearranged or the drive startup sequence changed. Be extremely careful during
write operations such as copying, saving, or formatting. Data or programs can
be overwritten if you select an incorrect drive.
General error messages appear if a problem or conflict is found by a program,
the operating system, or both. For an explanation of these messages, refer to
the information supplied with that software package.
Use the following procedure to help determine the cause of the problem: 1.
Turn off the computer and all external devices. 2. Check all cables and power
cords. 3. Set all display controls to the middle position. 4. Turn on all
external devices. 5. Turn on the computer. · Look for displayed error codes. ·
Listen for beep codes. · Look for readable instructions or a main menu on the
display. If you did not receive the correct response, proceed to step 6 on
page 31. If you do receive the correct response, proceed to step 7 on page 31.
6. Look at the following conditions and follow the instructions: · If you hear
beep codes during POST, go to “Beep symptoms” on page 33. · If the computer
displays a POST error, go to “POST error codes” on page 34. · If the computer
hangs and no error is displayed, continue at step 7 on page 31. 7. Run the
Diagnostic programs. See Chapter 6 “Diagnostics” on page 41. · If you receive
an error, replace the part that the diagnostic program calls out. · If the
test stops and you cannot continue, replace the last device tested.
Problem determination tips
Due to 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. · Machine type and
model · Processor or hard disk drive upgrades · Failure symptom
Do diagnostics indicate a failure? What, when, where, single, or multiple
systems? Is the failure repeatable? Has this configuration ever worked?
© Copyright Lenovo 2024
31
If it has been working, what changes were made prior to its failing? Is
this the original reported failure? · Diagnostics version Type and version
level · Hardware configuration Print (print screen) configuration currently
in use BIOS level · Operating system software Type and version level
Notes: 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 adapters/attachments in the same locations 4. Have the same
address jumpers/terminators/cabling 5. Have the same software versions and
levels 6. Have the same Diagnostic Diskettes (version) 7. Have the same
configuration options set in the system 8. Have the same setup for the
operating system control files
Comparing the configuration and software set-up between “working and non-
working” systems will often lead to problem resolution.
Symptom-to-FRU index
The Symptom-to-FRU index lists error symptoms and possible causes. The most
likely cause is listed first. Always begin with “Service checkout” on page 31.
This index can also be used to help you decide which FRUs to have available
when servicing a computer. If you are unable to correct the problem using this
index, go to “Undetermined problems” on page 36.
Notes:
· The Symptom-to-FRU index is not specific to any machine type and are
applicable to all computers. · If you have both an error message and an
incorrect audio response, diagnose the error message first. · If you cannot
run the diagnostic tests or you get a diagnostic error code when running a
test, but did receive a
POST error message, diagnose the POST error message first. · If you did not
receive any error message, look for a description of your error symptoms in
the first part of this index.

RAID
What is RAID
Redundant Array of Independent Disks (RAID) is a technology that provides
increased storage functions and reliability through redundancy. It also can
improve data storage reliability and fault tolerance compared with single-
drive storage systems. Data loss resulting from a drive failure can be
prevented by reconstructing missing data from the remaining drives.
When a group of independent physical storage drives is set up to use RAID
technology, they are in a RAID array. This array distributes data across
multiple storage drives, but the array appears to the host computer as one
single storage unit. Creating and using RAID arrays provides high performance,
such as the expedited I/O performance, because several drives can be accessed
simultaneously.
RAID Level
Your computer must have the minimum number of SATA or NVMe storage drives
installed for the supported level of RAID below: · RAID 0: striped disk array
Consists of at least two SATA or NVMe storage drives Supported strip size:
4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB Better performance without fault
tolerance · RAID 1: mirrored disk array Consists of two SATA or NVMe storage
drives Improved reading performance and 100% redundancy · RAID 5: block-
level striped disk array with distributed parity Consists of at least three
SATA storage drives Supported strip size: 16 KB, 32 KB, 64 KB, or 128 KB
Better performance and fault tolerance · RAID 10: striped and mirrored disk
array Consists of at least four SATA storage drives Supported strip size:
4 KB, 8 KB, 16 KB, 32 KB, or 64 KB Better performance without fault
tolerance Improved reading performance and 100% redundancy
Configure the system BIOS to enable SATA RAID functionality
To enable SATA RAID functionality: 1. Restart the computer. When the logo
screen is displayed, press F1 or Fn+F1. 2. Select Devices Storage Setup and
press Enter. 3. Select Configure Storage as and press Enter. 4. Select RAID
and press Enter. 5. Press F10 or Fn+F10 to save the changes and exit.

Hardware removal and installation
This chapter provides instructions on how to remove and install hardware for your computer.
Handling static-sensitive devices
Do not open the static-protective package containing the new part until the
defective part has been removed and you are ready to install the new part.
Static electricity, although harmless to you, can seriously damage computer
components and options.
When you handle options and other computer components, take these precautions
to avoid static-electricity damage:
· Limit your movement. Movement can cause static electricity to build up
around you.
· Always handle options and other computer components carefully. Handle
PCI/PCIe cards, memory modules, system boards, and microprocessors by the
edges. Never touch any exposed circuitry.
· Prevent others from touching the options and other computer components.
· Touch the static-protective package containing the part to a metal
expansion-slot cover or other unpainted metal surface on the computer for at
least two seconds. This reduces static electricity from the package and your
body before you install or replace a new part.
· When possible, remove the new part from the static-protective package, and
install it directly in the computer without setting the part down. When this
is not possible, place the static-protective package on a smooth, level
surface and place the part on the package.
· Do not place the part on the computer cover or other metal surface.
