iv ThinkSmart Hub Hardware Maintenance Manual
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 hub. During operation, some components become hot
enough to burn the skin. Before you open the cover, turn off the hub, 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 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.
2ThinkSmart Hub 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 hub. 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 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 hub.
Grounding requirements
Electrical grounding of the hub 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.
• 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 solid-state drive
Always try to run a low-level format operation before replacing 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 hub 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.
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.

Chapter 4. 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 hub 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 hub 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 hub.
• Look for displayed error 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 the hub displays a POST error, go to “POST error codes” on page 33.
• If the hub hangs and no error is displayed, continue at step 7 on page 31.
7. Run the Diagnostic programs. See “Diagnostics” on page 43.
• 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?
– If it has been working, what changes were made prior to its failing?
– Is this the original reported failure?
© Copyright Lenovo 2020 31
• 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 hub. 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 hubs.
• 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.
Power supply problems
If you suspect a power problem, use the following procedures.
32 ThinkSmart Hub Hardware Maintenance Manual

Chapter 6. Hardware removal and installation
This chapter provides instructions on how to remove and install hardware for your hub.
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
hub components and options.
When you handle options and other hub 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 hub 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 hub components.
• Touch the static-protective package containing the part to a metal expansion-slot cover or other
unpainted metal surface on the hub 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 hub
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 hub cover or other metal surface.
Service tool kit
Ensure that the following common service tool kit is prepared before you service the hub.
No. Tool name Tool type
1 Phillips-head screwdriver Common tool
2Torx-head screwdriver (for new Intel Xeon CPUs) Common tool

gaps. The hexagonal socket is used to pick up the antenna connectors.
Major FRUs and CRUs
Your hub contains the following types of CRUs and FRUs:
• Self-service CRUs: Refer to parts that can be installed or replaced easily by customer themselves or by
trained service technicians at an additional cost.
• Optional-service CRUs: Refer to parts that can be installed or replaced by customers with a greater skill
level. Trained service technicians can also provide service to install or replace the parts under the type of
warranty designated for the customer’s machine.
• FRUs: Refer to parts that must be installed or replaced only by trained service technicians. If customers
choose to replace the FRUs by themselves, the product warranty might be affected.
