Illustrations in this manual might look different from your product. Use this manual along with the advanced diagnostic tests to troubleshoot problems. Important: This manual is intended only for trained service technicians who are familiar with ThinkStation computers. Use this manual along with the advanced diagnostic tests to troubleshoot problems effectively. Before servicing a ThinkStation computer, be sure to read and understand Chapter 1 "Important safety information" on page 1. 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: 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. © Copyright Lenovo 2020 1 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. 2 P340 Hardware Maintenance Manual · 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 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. Chapter 1. Important safety information 3 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: · 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. 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.

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 storage drives installed for the supported level of RAID below: · RAID 0: striped disk array Consists of at least two SATA 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 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.
