Chapter 1. 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:

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 PX 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.

Chapter 2. 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/ ht507251 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.

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 37. If you do receive the correct response, proceed to step 7 on page 37. 6. Look at the following conditions and follow the instructions: · If you hear beep codes during POST, go to “Beep symptoms” on page 39. · If the computer displays a POST error, go to “POST error codes” on page 40. · If the computer hangs and no error is displayed, continue at step 7 on page 37. 7. Run the Diagnostic programs. See Chapter 6 “Diagnostics” on page 51. · 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 2023

37

­ 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 37. 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 43.
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.

Chapter 5. 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.
Configure RAID with Intel RSTe
If your computer comes with the Intel RSTe configuration utility, you can follow the sections below to configure RAID with Intel RSTe.
Storage drive requirements for RAID levels Your computer supports the following RAID levels: · RAID 0: striped disk array

Chapter 7. 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.
