Particulate contamination
Attention: Airborne particulates (including metal flakes or particles) and reactive gases acting alone or in
combination with other environmental factors such as humidity or temperature might pose a risk to the
device that is described in this document.
Risks that are posed by the presence of excessive particulate levels or concentrations of harmful gases
include damage that might cause the device to malfunction or cease functioning altogether. This
specification sets forth limits for particulates and gases that are intended to avoid such damage. The limits
must not be viewed or used as definitive limits, because numerous other factors, such as temperature or
moisture content of the air, can influence the impact of particulates or environmental corrosives and gaseous
contaminant transfer. In the absence of specific limits that are set forth in this document, you must
implement practices that maintain particulate and gas levels that are consistent with the protection of human
health and safety. If Lenovo determines that the levels of particulates or gases in your environment have
caused damage to the device, Lenovo may condition provision of repair or replacement of devices or parts
8ThinkSystem ST250 Maintenance Manual
on implementation of appropriate remedial measures to mitigate such environmental contamination.
Implementation of such remedial measures is a customer responsibility.
Table 2. Limits for particulates and gases
Contaminant Limits
Reactive gases Severity level G1 as per ANSI/ISA 71.04-19851:
• The copper reactivity level shall be less than 300 Angstroms per month (Å/month ≈ 0.0039 μg/
cm2-hour weight gain).2
• The silver reactivity level shall be less than 200 Å/month (Å/month ≈ 0.0035 μg/cm2-hour
weight gain).3
• The reactive monitoring of gaseous corrosivity must be conducted approximately 5 cm (2 in.) in
front of the rack on the air inlet side at one-quarter and three-quarter frame height off the floor
or where the air velocity is much higher.
Airborne
particulates Data centers must meet the cleanliness level of ISO 14644-1 class 8.
For data centers without airside economizer, the ISO 14644-1 class 8 cleanliness might be met by
choosing one of the following filtration methods:
• The room air might be continuously filtered with MERV 8 filters.
• Air entering a data center might be filtered with MERV 11 or preferably MERV 13 filters.
For data centers with airside economizers, the choice of filters to achieve ISO class 8 cleanliness
depends on the specific conditions present at that data center.
• The deliquescent relative humidity of the particulate contamination should be more than 60%
RH.4
• Data centers must be free of zinc whiskers.5
1 ANSI/ISA-71.04-1985. Environmental conditions for process measurement and control systems: Airborne
contaminants. Instrument Society of America, Research Triangle Park, North Carolina, U.S.A.
2 The derivation of the equivalence between the rate of copper corrosion growth in the thickness of the corrosion
product in Å/month and the rate of weight gain assumes that Cu2S and Cu2O grow in equal proportions.
3 The derivation of the equivalence between the rate of silver corrosion growth in the thickness of the corrosion
product in Å/month and the rate of weight gain assumes that Ag2S is the only corrosion product.
4 The deliquescent relative humidity of particulate contamination is the relative humidity at which the dust absorbs
enough water to become wet and promote ionic conduction.
5 Surface debris is randomly collected from 10 areas of the data center on a 1.5 cm diameter disk of sticky
electrically conductive tape on a metal stub. If examination of the sticky tape in a scanning electron microscope
reveals no zinc whiskers, the data center is considered free of zinc whiskers.

UpdateXpress System Packs (UXSPs)
Lenovo typically releases firmware in bundles called UpdateXpress System Packs (UXSPs). To ensure that all
of the firmware updates are compatible, you should update all firmware at the same time. If you are updating
firmware for both the Lenovo XClarity Controller and UEFI, update the firmware for Lenovo XClarity Controller
first.
Update method terminology
• In-band update. The installation or update is performed using a tool or application within an operating
system that is executing on the server’s core CPU.
• Out-of-band update. The installation or update is performed by the Lenovo XClarity Controller collecting
the update and then directing the update to the target subsystem or device. Out-of-band updates have no
dependency on an operating system executing on the core CPU. However, most out-of-band operations
do require the server to be in the S0 (Working) power state.
• On-Target update. The installation or update is initiated from an Operating System executing on the
server’s operating system.
• Off-Target update. The installation or update is initiated from a computing device interacting directly with
the server’s Lenovo XClarity Controller.
• UpdateXpress System Packs (UXSPs). UXSPs are bundled updates designed and tested to provide the
interdependent level of functionality, performance, and compatibility. UXSPs are server machine-type
specific and are built (with firmware and device driver updates) to support specific Windows Server, Red
Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES) operating system distributions.
Machine-type-specific firmware-only UXSPs are also available.

Internal cable routing
Some of the components in the server come with internal cables meant for specific connectors.
Before connecting the cables, read the following guidelines carefully:
• Turn off the server before you connect or disconnect any internal cables.
• Refer to the documentation that comes with any external devices for additional cabling instructions.
• Make use of the identifiers printed on the cables to locate the proper connectors.
• Ensure that the cable is not pinched and does not cover any connectors or obstruct any components on
the system board.
Notes:
1. Disengage all latches, release tabs, or locks on cable connectors when you disconnect cables from the
system board. Failing to release them before removing the cables will damage the cable sockets on the

Installation guidelines
Before installing components in your server, read the installation guidelines.
Before installing optional devices, read the following notices carefully:
Attention: Prevent exposure to static electricity, which might lead to system halt and loss of data, by
keeping static-sensitive components in their static-protective packages until installation, and handling these
devices with an electrostatic-discharge wrist strap or other grounding system.
• Read the safety information and guidelines to ensure your safety at work:
– A complete list of safety information for all products is available at:
http://thinksystem.lenovofiles.com/help/topic/safety_documentation/pdf_files.html
– “Handling static-sensitive devices” on page 55
• Make sure the components you are installing are supported by the server. For a list of supported optional
components for the server, see https://static.lenovo.com/us/en/serverproven/index.shtml.
• When you install a new server, download and apply the latest firmware. This will help ensure that any
known issues are addressed, and that your server is ready to work with optimal performance. Go to
ThinkSystem ST250 Drivers and Software to download firmware updates for your server.
Important: Some cluster solutions require specific code levels or coordinated code updates. If the
component is part of a cluster solution, verify that the latest level of code is supported for the cluster
solution before you update the code.
• It is good practice to make sure that the server is working correctly before you install an optional
component.
• Keep the working area clean, and place removed components on a flat and smooth surface that does not
shake or tilt.
• Do not attempt to lift an object that might be too heavy for you. If you have to lift a heavy object, read the
following precautions carefully:
– Make sure that you can stand steadily without slipping.
– Distribute the weight of the object equally between your feet.
– Use a slow lifting force. Never move suddenly or twist when you lift a heavy object.
– To avoid straining the muscles in your back, lift by standing or by pushing up with your leg muscles.
© Copyright Lenovo 2018, 2022 53
• Make sure that you have an adequate number of properly grounded electrical outlets for the server,
monitor, and other devices.
• Back up all important data before you make changes related to the disk drives.
• Have a small flat-blade screwdriver, a small Phillips screwdriver, and a T8 torx screwdriver available.
• You do not have to turn off the server to remove or install hot-swap power supplies or hot-plug USB
devices. However, you must turn off the server before you perform any steps that involve removing or
installing adapter cables, and you must disconnect the power source from the server before you perform
any steps that involve removing or installing a DIMM.
• Blue on a component indicates touch points, where you can grip to remove a component from or install it
in the server, open or close a latch, and so on.
• Terra-cotta on a component or an orange label on or near a component indicates that the component can
be hot-swapped if the server and operating system support hot-swap capability, which means that you
can remove or install the component while the server is still running. (Orange can also indicate touch
points on hot-swap components.) See the instructions for removing or installing a specific hot-swap
component for any additional procedures that you might have to perform before you remove or install the
component.
• The Red strip on the drives, adjacent to the release latch, indicates that the drive can be hot-swapped if
the server and operating system support hot-swap capability. This means that you can remove or install
the drive while the server is still running.
Note: See the system specific instructions for removing or installing a hot-swap drive for any additional
procedures that you might need to perform before you remove or install the drive.
• After finishing working on the server, make sure you reinstall all safety shields, guards, labels, and ground
wires.
System reliability guidelines
Review the system reliability guidelines to ensure proper system cooling and reliability.
Make sure the following requirements are met:
• When the server comes with redundant power, a power supply must be installed in each power-supply
bay.
• Adequate space around the server must be spared to allow server cooling system to work properly. Leave
approximately 50 mm (2.0 in.) of open space around the front and rear of the server. Do not place any
object in front of the fans.
• For proper cooling and airflow, refit the server cover before you turn the power on. Do not operate the
server for more than 30 minutes with the server cover removed, for it might damage server components.
• Cabling instructions that come with optional components must be followed.
• A failed fan must be replaced within 48 hours since malfunction.
• A removed hot-swap drive must be replaced within two minutes after removal.
• A removed hot-swap power supply must be replaced within two minutes after removal.
• Every air baffle that comes with the server must be installed when the server starts (some servers might
come with more than one air baffle). Operating the server with a missing air baffle might damage the
processor.
• All processor sockets must contain either a socket cover or a processor with heat sink.
• When more than one processor is installed, fan population rules for each server must be strictly followed.
54 ThinkSystem ST250 Maintenance Manual
Working inside the server with the power on
You might need to keep the power on with the server cover removed to look at system information on the
display panel or to replace hot-swap components. Review these guidelines before doing so.
Attention: The server might stop and loss of data might occur when internal server components are
exposed to static electricity. To avoid this potential problem, always use an electrostatic-discharge wrist
strap or other grounding systems when working inside the server with the power on.
• Avoid loose-fitting clothing, particularly around your forearms. Button or roll up long sleeves before
working inside the server.
• Prevent your necktie, scarf, badge rope, or long hair from dangling into the server.
• Remove jewelry, such as bracelets, necklaces, rings, cuff links, and wrist watches.
• Remove items from your shirt pocket, such as pens and pencils, in case they fall into the server as you
lean over it.
• Avoid dropping any metallic objects, such as paper clips, hairpins, and screws, into the server.
Handling static-sensitive devices
Review these guidelines before you handle static-sensitive devices to reduce the possibility of damage from
electrostatic discharge.
Attention: Prevent exposure to static electricity, which might lead to system halt and loss of data, by
keeping static-sensitive components in their static-protective packages until installation, and handling these
devices with an electrostatic-discharge wrist strap or other grounding system.
• Limit your movement to prevent building up static electricity around you.
• Take additional care when handling devices during cold weather, for heating would reduce indoor
humidity and increase static electricity.
• Always use an electrostatic-discharge wrist strap or other grounding system.
• While the device is still in its static-protective package, touch it to an unpainted metal surface on the
outside of the server for at least two seconds. This drains static electricity from the package and from your
body.
• Remove the device from the package and install it directly into the server without putting it down. If it is
necessary to put the device down, put it back into the static-protective package. Never place the device
on the server or on any metal surface.
• When handling a device, carefully hold it by the edges or the frame.
• Do not touch solder joints, pins, or exposed circuitry.
• Keep the device from others’ reach to prevent possible damages.

Enable TPM
The server supports Trusted Platform Module (TPM), Version 1.2 or Version 2.0.
Note: For customers in Chinese Mainland, TPM is not supported. However, customers in Chinese Mainland
can install a TPM card (sometimes called a daughter card).
When a system board is replaced, you must make sure that the TPM policy is set correctly.
CAUTION:
Take special care when setting the TPM policy. If it is not set correctly, the system board can become
unusable.
Set the TPM policy
By default, a replacement system board is shipped with the TPM policy set to undefined. You must modify
this setting to match the setting that was in place for the system board that is being replaced.
There are two methods available to set the TPM policy:
• From Lenovo XClarity Provisioning Manager
To set the TPM policy from Lenovo XClarity Provisioning Manager:
1. Start the server and press the key according to the on-screen instructions to display the Lenovo
XClarity Provisioning Manager interface.
2. If the power-on Administrator password is required, enter the password.
3. From the System Summary page, click Update VPD.
4. Set the policy to one of the following settings.
– TPM 2.0 enabled - Chinese Mainland only. Customers in the Chinese Mainland should choose
this setting if a NationZ TPM 2.0 adapter is installed.
– TPM enabled - ROW. Customers outside of the Chinese Mainland should choose this setting.
– Permanently disabled. Customers in the Chinese Mainland should use this setting if no TPM
adapter is installed.
Note: Although the setting undefined is available as a policy setting, it should not be used.
• From Lenovo XClarity Essentials OneCLI
Note: Please note that a Local IPMI user and password must be setup in Lenovo XClarity Controller for
remote accessing to the target system.
To set the TPM policy from Lenovo XClarity Essentials OneCLI:
1. Read TpmTcmPolicyLock to check whether the TPM_TCM_POLICY has been locked:OneCli.exe config
show imm.TpmTcmPolicyLock --override --imm <userid>:<password>@<ip_address>
OneCli.exe config show imm.TpmTcmPolicyLock --override --imm <userid>:<password>@<ip_address>
Note: The imm.TpmTcmPolicyLock value must be 'Disabled', which means TPM_TCM_POLICY is
NOT locked and changes to the TPM_TCM_POLICY are permitted. If the return code is ‘Enabled’
then no changes to the policy are permitted. The planar may still be used if the desired setting is
correct for the system being replaced.
2. Configure the TPM_TCM_POLICY into XCC:
Chapter 3.Hardware replacement procedures 147
– For the customer in Chinese Mainland with no TCM/TPM:
OneCli.exe config set imm.TpmTcmPolicy "NeitherTpmNorTcm" --override --imm <userid>:<password>@<ip_
address>
– For the customer in Chinese Mainland that has installed TCM/TPM module on the original system
(TCM/TPM module should be moved to the FRU prior to changing policy)
OneCli.exe config set imm.TpmTcmPolicy "TcmOnly" --override --imm <userid>:<password>@<ip_address>
– For the customer outside of Chinese Mainland:
OneCli.exe config set imm.TpmTcmPolicy "TpmOnly" --override --imm <userid>:<password>@<ip_address>
3. Issue reset command to reset system:
OneCli.exe misc ospower reboot --imm <userid>:<password>@<ip_address>
4. Read back the value to check whether the change has been accepted:
OneCli.exe config show imm.TpmTcmPolicy --override --imm <userid>:<password>@<ip_address>
Notes:
– If the read back value is matched it means the TPM_TCM_POLICY has been set correctly.
imm.TpmTcmPolicy is defined as below:
– Value 0 use string “Undefined” , which means UNDEFINED policy.
– Value 1 use string “NeitherTpmNorTcm”, which means TPM_PERM_DISABLED.
– Value 2 use string “TpmOnly”, which means TPM_ALLOWED.
– Value 4 use string “TcmOnly”, which means TCM_ALLOWED.
– Below 4 steps must also be used to ‘lock’ the TPM_TCM_POLICY when using OneCli/ASU
commands:
5. Read TpmTcmPolicyLock to check whether the TPM_TCM_POLICY has been locked , command as
below:
OneCli.exe config show imm.TpmTcmPolicyLock --override --imm <userid>:<password>@<ip_address>
The value must be 'Disabled', it means TPM_TCM_POLICY is NOT locked and must be set.
6. Lock the TPM_TCM_POLICY:
OneCli.exe config set imm.TpmTcmPolicyLock "Enabled"--override --imm <userid>:<password>@<ip_address>
7. Issue reset command to reset system, command as below:
OneCli.exe misc ospower reboot --imm <userid>:<password>@<ip_address>
During the reset, UEFI will read the value from imm.TpmTcmPolicyLock, if the value is 'Enabled' and
the imm.TpmTcmPolicy value is valid, UEFI will lock the TPM_TCM_POLICY setting.
Note: The valid value for imm.TpmTcmPolicy includes 'NeitherTpmNorTcm', 'TpmOnly' and
'TpmOnly'.
If the imm.TpmTcmPolicy is set as 'Enabled' but imm.TpmTcmPolicy value is invalid, UEFI will reject
the 'lock' request and change imm.TpmTcmPolicy back to 'Disabled'.
8. Read back the value to check whether the ‘Lock’ is accepted or rejected. command as below:
OneCli.exe config show imm.TpmTcmPolicy --override --imm <userid>:<password>@<ip_address>
Note: If the read back value is changed from 'Disabled' to 'Enabled' that means the TPM_TCM_
POLICY has been locked successfully. There is no method to unlock a policy once it has been set
other than replacing system board.
148 ThinkSystem ST250 Maintenance Manual
imm.TpmTcmPolicyLock is defined as below:
Value 1 use string “Enabled" , which means lock the policy. Other values are not accepted.

156 ThinkSystem ST250 Maintenance Manual
Chapter 4. Problem determination
Use the information in this section to isolate and resolve issues that you might encounter while using your
server.
Lenovo servers can be configured to automatically notify Lenovo Support if certain events are generated.
You can configure automatic notification, also known as Call Home, from management applications, such as
the Lenovo XClarity Administrator. If you configure automatic problem notification, Lenovo Support is
automatically alerted whenever a server encounters a potentially significant event.
To isolate a problem, you should typically begin with the event log of the application that is managing the
server:
• If you are managing the server from the Lenovo XClarity Administrator, begin with the Lenovo XClarity
Administrator event log.
• If you are using some other management application, begin with the Lenovo XClarity Controller event log.
Notes:
• For your server, the Lenovo XClarity Controller web page or command-line interface does not support the
display of system utilization information for the following:
– Processor
– DIMM
– I/O
Event logs
An alert is a message or other indication that signals an event or an impending event. Alerts are generated by
the Lenovo XClarity Controller or by UEFI in the servers. These alerts are stored in the Lenovo XClarity
Controller Event Log. If the server is managed by the Chassis Management Module 2 or by the Lenovo
XClarity Administrator, alerts are automatically forwarded to those management applications.
Note: For a listing of events, including user actions that might need to be performed to recover from an
event, see the Messages and Codes Reference, which is available at:http://thinksystem.lenovofiles.com/
help/topic/7X09/pdf_files.html
Lenovo XClarity Administrator event log
If you are using Lenovo XClarity Administrator to manage server, network, and storage hardware, you can
view the events from all managed devices through the XClarity Administrator.
© Copyright Lenovo 2018, 2022 157
Figure 114. Lenovo XClarity Administrator event log
For more information about working with events from XClarity Administrator, see:
http://sysmgt.lenovofiles.com/help/topic/com.lenovo.lxca.doc/events_vieweventlog.html
Lenovo XClarity Controller event log
The Lenovo XClarity Controller monitors the physical state of the server and its components using sensors
that measure internal physical variables such as temperature, power-supply voltages, fan speeds, and
component status. The Lenovo XClarity Controller provides various interfaces to systems management
software and to system administrators and users to enable remote management and control of a server.
The Lenovo XClarity Controller monitors all components of the server and posts events in the Lenovo
XClarity Controller event log.
Figure 115. Lenovo XClarity Controller event log
For more information about accessing the Lenovo XClarity Controller event log, see:
158 ThinkSystem ST250 Maintenance Manual
“Viewing Event Logs” section in the XCC documentation compatible with your server at https://
sysmgt.lenovofiles.com/help/topic/lxcc_frontend/lxcc_overview.html
General problem determination procedures
Use the information in this section to resolve problems if the event log does not contain specific errors or the
server is inoperative.
If you are not sure about the cause of a problem and the power supplies are working correctly, complete the
following steps to attempt to resolve the problem:
1. Power off the server.
2. Make sure that the server is cabled correctly.
3. Remove or disconnect the following devices if applicable, one at a time, until you find the failure. Power
on and configure the server each time you remove or disconnect a device.
• Any external devices.
• Surge-suppressor device (on the server).
• Printer, mouse, and non-Lenovo devices.
• Each adapter.
• Hard disk drives.
• Memory modules until you reach the minimum configuration that is supported for the server.
See “Specifications” on page 3 to determine the minimum configuration for your server.
4. Power on the server.
If the problem is solved when you remove an adapter from the server, but the problem recurs when you
install the same adapter again, suspect the adapter. If the problem recurs when you replace the adapter with
a different one, try a different PCIe slot.
If the problem appears to be a networking problem and the server passes all system tests, suspect a network
cabling problem that is external to the server.
Resolving suspected power problems
Power problems can be difficult to solve. For example, a short circuit can exist anywhere on any of the power
distribution buses. Usually, a short circuit will cause the power subsystem to shut down because of an
overcurrent condition.
Complete the following steps to diagnose and resolve a suspected power problem.
Step 1. Check the event log and resolve any errors related to the power.
Note: Start with the event log of the application that is managing the server. For more information
about event logs, see “Event logs” on page 157.
Step 2. Check for short circuits, for example, if a loose screw is causing a short circuit on a circuit board.
Step 3. Remove the adapters and disconnect the cables and power cords to all internal and external
devices until the server is at the minimum configuration that is required for the server to start. See
“Specifications” on page 3 to determine the minimum configuration for your server.
Step 4. Reconnect all ac power cords and turn on the server. If the server starts successfully, reseat the
adapters and devices one at a time until the problem is isolated.
If the server does not start from the minimum configuration, replace the components in the minimum
configuration one at a time until the problem is isolated.
Chapter 4.Problem determination 159
Resolving suspected Ethernet controller problems
The method that you use to test the Ethernet controller depends on which operating system you are using.
See the operating-system documentation for information about Ethernet controllers, and see the Ethernet
controller device-driver readme file.
Complete the following steps to attempt to resolve suspected problems with the Ethernet controller.
Step 1. Make sure that the correct device drivers, which come with the server are installed and that they
are at the latest level.
Step 2. Make sure that the Ethernet cable is installed correctly.
• The cable must be securely attached at all connections. If the cable is attached but the problem
remains, try a different cable.
• If you set the Ethernet controller to operate at 100 Mbps or 1000 Mbps, you must use Category
5 cabling.
Step 3. Determine whether the hub supports auto-negotiation. If it does not, try configuring the integrated
Ethernet controller manually to match the speed and duplex mode of the hub.
Step 4. Check the Ethernet controller LEDs on the rear panel of the server. These LEDs indicate whether
there is a problem with the connector, cable, or hub.
• The Ethernet link status LED is lit when the Ethernet controller receives a link pulse from the hub.
If the LED is off, there might be a defective connector or cable or a problem with the hub.
• The Ethernet transmit/receive activity LED is lit when the Ethernet controller sends or receives
data over the Ethernet network. If the Ethernet transmit/receive activity is off, make sure that the
hub and network are operating and that the correct device drivers are installed.
Step 5. Check the Network activity LED on the rear of the server. The Network activity LED is lit when data
is active on the Ethernet network. If the Network activity LED is off, make sure that the hub and
network are operating and that the correct device drivers are installed.
Step 6. Check for operating-system-specific causes of the problem, and also make sure that the operating
system drivers are installed correctly.
Step 7. Make sure that the device drivers on the client and server are using the same protocol.
If the Ethernet controller still cannot connect to the network but the hardware appears to be working, the
network administrator must investigate other possible causes of the error.
Troubleshooting by symptom
Follow this procedure to find solutions to problems that have identifiable symptoms.
To use the symptom-based troubleshooting information in this section, complete the following steps:
1. Check the event log of the application that is managing the server and follow the suggested actions to
resolve any event codes.
• If you are managing the server from the Lenovo XClarity Administrator, begin with the Lenovo XClarity
Administrator event log.
• If you are using some other management application, begin with the Lenovo XClarity Controller event
log.
For more information about event logs, see “Event logs” on page 157.
2. Review this section to find the symptoms that you are experiencing and follow the suggested actions to
resolve the issue.
3. If the problem persists, contact support (see “Contacting Support” on page 177).

When referring to hard disk drive capacity or communications volume, MB stands for 1 000 000 bytes, and
GB stands for 1 000 000 000 bytes. Total user-accessible capacity can vary depending on operating
environments.
Maximum internal hard disk drive capacities assume the replacement of any standard hard disk drives and
population of all hard-disk-drive bays with the largest currently supported drives that are available from
Lenovo.
Maximum memory might require replacement of the standard memory with an optional memory module.
Each solid-state memory cell has an intrinsic, finite number of write cycles that the cell can incur. Therefore, a
solid-state device has a maximum number of write cycles that it can be subjected to, expressed as total
bytes written (TBW). A device that has exceeded this limit might fail to respond to system-generated
commands or might be incapable of being written to. Lenovo is not responsible for replacement of a device
that has exceeded its maximum guaranteed number of program/erase cycles, as documented in the Official
Published Specifications for the device.
Lenovo makes no representations or warranties with respect to non-Lenovo products. Support (if any) for the
non-Lenovo products is provided by the third party, not Lenovo.
Some software might differ from its retail version (if available) and might not include user manuals or all
program functionality.
Telecommunication regulatory statement
This product may not be certified in your country for connection by any means whatsoever to interfaces of
public telecommunications networks. Further certification may be required by law prior to making any such
connection. Contact a Lenovo representative or reseller for any questions.
