  • Fan 4 installed
  • Two hot-swap power supplies installed
    • NVMe SSD not installed
    • Graphics adapters not installed
  • SAS drives with capacity larger than or equal to 2 TB not installed in the expansion drive cage

Firmware updates

Several options are available to update the firmware for the server.

You can use the tools listed here to update the most current firmware for your server and the devices that are installed in the server.

Note: 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.

Important 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.

Chapter 3. Hardware replacement procedures

This section provides installation and removal procedures for all serviceable system components. Each component replacement procedure references any tasks that need to be performed to gain access to the component being replaced.

For more information about ordering parts:

http://datacentersupport.lenovo.com/us/en/products/servers/thinksystem/st550/7x09/parts

Note: If you replace a part, such as an adapter, that contains firmware, you might also need to update the firmware for that part. For more information about updating firmware, see “Firmware updates” on page 7.

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 that you work safely.

  • 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 56

- Make sure the components you are installing are supported by the server. For a list of supported optional components for the server, see http://www.lenovo.com/serverproven/.

- 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 ST550 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.

- 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.

- Orange 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.

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.

DIMM installation rules

DIMMs must be installed in a specific order based on the memory configuration that you implement on your server.

Your server has 12 DIMM slots with the following features:

  • Each slot supports 8 GB, 16 GB, and 32 GB DDR4 RDIMMs with Error Checking and Correcting (ECC) technology.
    • Each slot supports 64 GB DDR4 LRDIMMs with ECC technology.
  • Your server supports up to 6 DIMMs when one processor is installed, and up to 12 DIMMs when two processors are installed.
  • The minimum system memory is 8 GB (only one processor installed and only one 8 GB RDIMM installed in the CPU1 DIMM3 slot).
  • The maximum system memory is as follows:

  • 384 GB using RDIMMs (two processors installed and one 32 GB RDIMM installed in each of the 12 DIMM slots)

  • 768 GB using LRDIMMs (two processors installed and one 64 GB LRDIMM installed in each of the 12 DIMM slots)

For a list of supported DIMM options, see: http://www.lenovo.com/serverproven/

Before installing a DIMM, ensure that all DIMMs to be installed must be the same type. Your server supports the following types of DIMMs:

• DDR4 RDIMM with ECC technology
• DDR4 LRDIMM with ECC technology

The following illustration helps you to locate the DIMM slots on the system board.

Figure 84. DIMM slots on the system board

Your server supports the following memory modes:

• "Independent mode" on page 107
- "Mirroring mode" on page 108
• "Rank sparing mode" on page 109

Independent mode

Independent mode provides high performance memory capability. You can populate all channels with no matching requirements. Individual channels can run at different DIMM timings, but all channels must run at the same interface frequency.

Notes:

  • All DIMMs to be installed must be the same type.

- When you install DIMMs with same rank and different capacity, install the DIMM that has the highest capacity first.

The following table shows the DIMM population sequence for independent mode when only one processor (CPU1) is installed.

Note: If there are three identical DIMMs to be installed for CPU1, and the three DIMMs have the same Lenovo part number, install the three DIMMs in slots 1, 2, and 3.

6 1 23 4 5 6 6

The following table shows the DIMM population sequence for independent mode when two processors (CPU1 and CPU2) are installed.

Notes:

  • If there are three identical DIMMs to be installed for CPU1, and the three DIMMs have the same Lenovo part number, install the three DIMMs in slots 1, 2, and 3.
  • If there are three identical DIMMs to be installed for CPU2, and the three DIMMs have the same Lenovo part numbers, install the three DIMMs in slots 10, 11, and 12.

Mirroring mode

In mirroring mode, each DIMM in a pair must be identical in size and architecture. The channels are grouped in pairs with each channel receiving the same data. One channel is used as a backup of the other, which provides redundancy.

Note: All memory modules to be installed must be the same type with the same capacity, frequency, voltage, and number of ranks.

The following table shows the DIMM population sequence for mirroring mode when only one processor (CPU1) is installed.

Rank sparing mode

In rank sparing mode, one rank of a DIMM works as the spare rank for the other ranks on the same channel. The spare rank is not available as system memory.

Notes:

  • All DIMMs to be installed must be the same type with the same capacity, frequency, voltage, and ranks.
  • If the rank of installed DIMMs is one rank, rank sparing mode is not supported. If the rank of installed DIMMs is more than one rank, follow the installation rules listed in the following tables.

Processor and heat sink replacement

Use the following procedures to replace an assembled processor and heat sink, known as a processor-heat-sink module (PHM), a processor, or a heat sink.

Attention: Before you begin replacing a processor, make sure that you have an alcohol cleaning pad (part number 00MP352) and blue thermal grease (part number 01KP765). Do not use gray thermal grease (part number 41Y9292) when replacing a ThinkSystem ST550 processor.

Important: The processor in your server can throttle, temporarily lowering speed to reduce heat output, in response to thermal conditions. In instances where the throttling period is of extremely short duration (100 ms or less), the only indication will be an entry in the event log. In these instances the event can be ignored and processor replacement is not required.

Remove a processor and heat sink

Processors are in the compute system boards that are accessed from the front of the server. This task has instructions for removing an assembled processor and heat sink, known as a processor-heat-sink module (PHM), a processor, and a heat sink. All of these tasks require a Torx T30 driver.

ATTENTION: Static Sensitive Device Ground package before opening

Attention:

  • Each processor socket must always contain a cover or a PHM. When removing or installing a PHM, protect empty processor sockets with a cover.
  • Do not touch the processor socket or processor contacts. Processor-socket contacts are very fragile and easily damaged. Contaminants on the processor contacts, such as oil from your skin, can cause connection failures.
  • Remove and install only one PHM at a time. If the system board supports multiple processors, install the PHMs starting with the first processor socket.
  • Do not allow the thermal grease on the processor or heat sink to come in contact with anything. Contact with any surface can compromise the thermal grease, rendering it ineffective. Thermal grease can damage components, such as electrical connectors in the processor socket. Do not remove the grease cover from a heat sink until you are instructed to do so.

Before removing a PHM:

Note: The heat sink, processor, and processor retainer for your system might be different than those shown in the illustrations.

ATTENTION: Static Sensitive Device Ground package before opening

Attention:

  • Each processor socket must always contain a cover or a PHM. When removing or installing a PHM, protect empty processor sockets with a cover.
  • Do not touch the processor socket or processor contacts. Processor-socket contacts are very fragile and easily damaged. Contaminants on the processor contacts, such as oil from your skin, can cause connection failures.
  • Remove and install only one PHM at a time. If the system board supports multiple processors, install the PHMs starting with the first processor socket.
  • Do not allow the thermal grease on the processor or heat sink to come in contact with anything. Contact with any surface can compromise the thermal grease, rendering it ineffective. Thermal grease can damage components, such as electrical connectors in the processor socket. Do not remove the grease cover from a heat sink until you are instructed to do so.

Notes:

  • PHMs are keyed for the socket where they can be installed and for their orientation in the socket.
  • See http://www.lenovo.com/serverproven/ for a list of processors supported for your server. All processors on the system board must have the same speed, number of cores, and frequency.
  • Before you install a new PHM or replacement processor, update your system firmware to the latest level. See “Firmware updates” on page 7.
  • Installing an additional PHM can change the memory requirements for your system. See “DIMM installation rules” on page 106 for a list of processor-to-memory relationships.
  • Optional devices available for your system might have specific processor requirements. See the documentation that comes with the optional device for information.

Before installing a PHM:

Note: The heat sink, processor, and processor retainer for your system might be different than those shown in the illustrations.

  1. Remove the existing PHM, if one is installed. See "Remove a processor and heat sink" on page 154.
  2. Replace the processor retainer of the replacement processor.

Note: Replacement processors come with both rectangular and square processor retainers. A rectangular retainer comes attached to the processor. You must remove the rectangular retainer and replace it with a square retainer. The rectangular retainer can be discarded.

a. Remove the rectangular processor retainer.

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 managing the server from the Chassis Management Module 2, begin with the Chassis Management Module 2 event log.
  • If you are using some other management application, begin with the Lenovo XClarity Controller event log.

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

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. Turn off the server.
  2. Ensure that the server is cabled correctly.
  3. Remove or disconnect the following devices, one at a time, until you find the failure. Turn on and configure the server each time you remove or disconnect a device.
  4. Any external devices
  5. Surge-suppressor device (on the server)
    • Printer, mouse, and non-Lenovo devices
  6. Each adapter
  7. Storage drives
  8. Memory modules until you reach the minimum configuration that is supported for the server

Note: The minimum configuration required for the server to start is one processor and one 8 GB DIMM.

  1. Turn 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 173.

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.

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 LAN activity LED on the rear of the server. The LAN activity LED is lit when data is active on the Ethernet network. If the LAN 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.

Trademarks

Lenovo, the Lenovo logo, and ThinkSystem are trademarks of Lenovo in the United States, other countries, or both.

Intel and Xeon are trademarks of Intel Corporation in the United States, other countries, or both.

Microsoft and Windows are trademarks of the Microsoft group of companies.

Linux is a registered trademark of Linus Torvalds.

Important notes

Processor speed indicates the internal clock speed of the microprocessor; other factors also affect application performance.

CD or DVD drive speed is the variable read rate. Actual speeds vary and are often less than the possible maximum.

When referring to processor storage, real and virtual storage, or channel volume, KB stands for 1 024 bytes, MB stands for 1 048 576 bytes, and GB stands for 1 073 741 824 bytes.

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.

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 on implementation of appropriate remedial measures to mitigate such environmental contamination. Implementation of such remedial measures is a customer responsibility.

Table 16. Limits for particulates and gases
