What your server offers

The server uses the following features and technologies.

v Integrated Management Module

The Integrated Management module (IMM) combines service processor functions, video controller, and (when an optional virtual media key is installed) remote presence function in a single chip. The IMM provides advanced service-processor control, monitoring, and alerting function. If an environmental condition exceeds a threshold or if a system component fails, the IMM lights LEDs to help you diagnose the problem, records the error in the event log, and alerts you to the problem. Optionally, the IMM also provides a virtual presence capability for remote server management capabilities. The IMM provides remote server management through the following industry-standard interfaces:

– Intelligent Platform Management Interface (IPMI) version 2.0 – Simple Network Management Protocol (SNMP) version 3 – Common Information Model (CIM) – Web browser For additional information, see “Using the integrated management module” on

page 122.

v UEFI-compliant server firmware IBM System x Server Firmware (server

firmware) offers several features, including Unified Extensible Firmware Interface (UEFI) 2.1 compliance; Active Energy Manager technology; enhanced reliability, availability, and serviceability (RAS) capabilities; and basic input/output system (BIOS) compatibility support. UEFI replaces the BIOS and defines a standard interface between the operating system, platform firmware, and external devices. UEFI-compliant System x servers are capable of booting UEFI-compliant operating systems, BIOS-based operating systems, and BIOS-based adapters as well as UEFI-compliant adapters.

Note: The server does not support DOS (Disk Operating System).

v IBM Dynamic System Analysis Preboot diagnostics programs

The Dynamic System Analysis (DSA) Preboot diagnostics programs are stored on the integrated USB memory. It collects and analyzes system information to aid in diagnosing server problems. The diagnostic programs collect the following information about the server:

– System configuration – Network interfaces and settings – Installed hardware – Light path diagnostics status – Service processor status and configuration – Vital product data, firmware, and UEFI (formerly BIOS) configuration – Hard disk drive health – RAID controller configuration – Event logs for ServeRAID controllers and service processors The diagnostic programs create a merged log that includes events from all

collected logs. The information is collected into a file that you can send to IBM service and support. Additionally, you can view the information locally through a generated text report file. You can also copy the log to a removable media and view the log from a Web browser.

For additional information about DSA Preboot diagnostics, see the Problem Determination and Service Guide on the IBM System x Documentation CD

The Active Memory feature improves the reliability of memory through memory mirroring. Memory mirroring mode replicates and stores data on two pairs of DIMMs within two channels simultaneously. If a failure occurs, the memory controller switches from the primary pair of memory DIMMs to the backup pair of DIMMs. For more information about installing DIMMs for memory mirroring, see “Installing a memory module” on page 54.

– Remote presence capability and blue-screen capture

The remote presence and blue-screen capture features are integrated functions of the Integrated Management Module (IMM) and are available with the purchase of the optional IBM Virtual Media Key. A virtual media key is required to enable the remote presence and blue-screen capture features. The remote presence feature provides the following functions:

- Remotely viewing video with graphics resolutions up to 1600 x 1200 at 75 Hz, regardless of the system state

- Remotely accessing the server, using the keyboard and mouse from a remote client

- Mapping the CD or DVD drive, diskette drive, and USB flash drive on a remote client, and mapping ISO and diskette image files as virtual drives that are available for use by the server

- Uploading a diskette image to the IMM memory and mapping it to the server as a virtual drive

The blue-screen capture feature captures the video display contents before the IMM restarts the server when the IMM detects an operating-system hang condition. A system administrator can use the blue-screen capture to assist in determining the cause of the hang condition.

See “Using the remote presence capability and blue-screen capture” on page 123 for additional information.

– Large system-memory capacity

The memory bus supports up to 192 GB of system memory when registered DIMMs are installed. The server supports up to 48 GB if unbuffered DIMMs are installed. The memory controller supports error correcting code (ECC) for up to 18 industry-standard PC3-10600R-999, 800, 1067, and 1333 MHz, DDR3 (third-generation double-data-rate), synchronous dynamic random access memory (SDRAM) dual inline memory modules (DIMMs).

v PCI adapter capabilities

The server has two PCI interface slots (one supports low-profile cards, and one supports half-length, full-height cards). Both slots can support PCI Express or PCI-X adapters through an optional PCI riser card. See “Installing an adapter” on page 70 for detailed information.

v Active Energy Manager

The IBM Active Energy Manager solution is an IBM Systems Director plug-in that measures and reports server power consumption as it occurs. This enables you to monitor power consumption in correlation to specific software application programs and hardware configurations. You can obtain the measurement values through the systems-management interface and view them, using IBM Systems Director. For more information, including the required levels of IBM Systems Director and Active Energy Manager, see the IBM Systems Director documentation on the IBM Systems Director CD,orsee http://www.ibm.com/systems/software/director/resources.html.

v Redundant connection

The addition of the optional Ethernet daughter card provides failover capability to a redundant Ethernet connection with the applicable application installed. If a problem occurs with the primary Ethernet connection and the optional Ethernet daughter card is installed on the server, all Ethernet traffic that is associated with the primary connection is automatically switched to the optional redundant

12 IBM System x3550 M3 Type 4254 and 7944: Installation and User's Guide

Ethernet daughter card connection. If the applicable device drivers are installed, this switching occurs without data loss and without user intervention.

v Redundant cooling and optional power capabilities

The server supports a maximum of two 675-watt or 460-watt hot-swap power supplies and six dual-motor hot-swap fans, which provide redundancy and hot-swap capability for a typical configuration. The redundant cooling by the fans in the server enables continued operation if one of the fans fails. The server comes with one 675-watt or 460-watt hot-swap power supply and five fans.

You must install the sixth fan when you install the second microprocessor in the server. You can order the second optional power supply for power redundancy.

Note: You cannot mix 460-watt and 675-watt power supplies, high-efficiency and non-high-efficiency power supplies, or ac and dc power supplies in the server.

v ServeRAID support

The ServeRAID adapter provides hardware redundant array of independent disks (RAID) support to create configurations. The standard RAID adapter provides RAID levels 0, 1, and 1E. An optional RAID adapter is available for purchase.

v Systems-management capabilities

The server comes with an integrated management module (IMM). When the IMM is used with the systems-management software that comes with the server, you can manage the functions of the server locally and remotely. The IMM also provides system monitoring, event recording, and network alert capability. The system-management connector on the rear of the server is dedicated to the IMM. The dedicated system-management connector provides additional security by physically separating the management network traffic from the production network. You can use the Setup utility to configure the server to use a dedicated systems-management network or a shared network.

v TCP/IP offload engine (TOE) support

The Ethernet controllers in the server support TOE, which is a technology that offloads the TCP/IP flow from the microprocessor and I/O subsystem to increase the speed of the TCP/IP flow. When an operating system that supports TOE is running on the server and TOE is enabled, the server supports TOE operation. See the operating-system documentation for information about enabling TOE.

Note: As of the date of this document, the Linux operating system does not support TOE.

Server power features

When the server is connected to a power source but is not turned on, the operating system does not run, and all core logic except for the service processor (the integrated management module) is shut down; however, the server can respond to requests from the service processor, such as a remote request to turn on the server.

The power-on LED flashes to indicate that the server is connected to a power source but is not turned on.

Turning on the server

Use this information to turn on the server.

Approximately 5 seconds after the server is connected to power, one or more fans might start running to provide cooling while the server is connected to power and the power-on button LED will blink quickly. Approximately 20 to 40 seconds after the server is connected to power, the power-control button becomes active (the power-on LED will blink slowly), and one or more fans might start running to provide cooling while the server is connected to power. You can turn on the server by pressing the power-control button.

The server can also be turned on in any of the following ways: v If a power failure occurs while the server is turned on, the server will restart

automatically when power is restored.

v If your operating system supports the Wake on LAN feature, the Wake on LAN

feature can turn on the server.

Note: When 4 GB or more of memory (physical or logical) is installed, some memory is reserved for various system resources and is unavailable to the operating system. The amount of memory that is reserved for system resources depends on the operating system, the configuration of the server, and the configured PCI options.

Turning off the server

Use this information to turn off the server.

When you turn off the server and leave it connected to power, the server can respond to requests from the service processor, such as a remote request to turn on the server. While the server remains connected to power, one or more fans might continue to run. To remove all power from the server, you must disconnect it from the power source.

Some operating systems require an orderly shutdown before you turn off the server. See your operating-system documentation for information about shutting down the operating system.

Statement 5

Chapter 1. The IBM System x3550 M3 server 33

The server can be turned off in any of the following ways: v You can turn off the server from the operating system, if your operating system

supports this feature. After an orderly shutdown of the operating system, the server will turn off automatically.

v You can press the power-control button to start an orderly shutdown of the

operating system and turn off the server, if your operating system supports this feature.

v If the operating system stops functioning, you can press and hold the

power-control button for more than 4 seconds to turn off the server.

v The server can be turned off by Wake on LAN feature with the following

limitation: – To install any PCI adapter, the power cords must be removed from the power

source before you remove the PCI Express riser assembly and the PCI-X riser assembly. Otherwise, this will cause the active power management event signal to become disabled by the system board logic and Wake on LAN might not work. However, after the server is powered-on locally, the active power management event signal will be enabled by the system board logic.

v The integrated management module (IMM) can turn off the server as an

automatic response to a critical system failure.

Attention: Static electricity that is released to internal server components when the server is powered-on might cause the system to halt, which might result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when removing or installing a hot-swap device.

Before you install optional devices, read the following information: v Read the safety information in “Safety” on page v, the guidelines in “Working

inside the server with the power on” on page 45, and “Handling static-sensitive devices” on page 46. This information will help you work safely.

v Make sure that the devices that you are installing are supported. For a list of

supported optional devices for the server, see http://www.ibm.com/systems/ info/x86servers/serverproven/compat/us/.

v When you install your new server, take the opportunity to download and apply

the most recent firmware updates. This step will help to ensure that any known issues are addressed and that your server is ready to function at maximum levels of performance. To download firmware updates for your server, go to http://www.ibm.com/support/fixcentral/.

Chapter 2. Installing optional devices 43

Important: Some cluster solutions require specific code levels or coordinated code updates. If the device is part of a cluster solution, verify that the latest level of code is supported for the cluster solution before you update the code.

For additional information about tools for updating, managing, and deploying firmware, see the ToolsCenter for System x and BladeCenter at http://publib.boulder.ibm.com/infocenter/toolsctr/v1r0/.

v Before you install optional hardware, make sure that the server is working

correctly. Start the server, and make sure that the operating system starts, if an operating system is installed, or that a 19990305 error code is displayed, indicating that an operating system was not found but the server is otherwise working correctly. If the server is not working correctly, see the Problem Determination and Service Guide on the IBM System x Documentation CD for diagnostic information.

v Observe good housekeeping in the area where you are working. Place removed

covers and other parts in a safe place.

v If you must start the server while the server cover is removed, make sure that

no one is near the server and that no tools or other objects have been left inside the server.

v Do not attempt to lift an object that you think is too heavy for you. If you have

to lift a heavy object, observe the following precautions: – Make sure that you can stand safely 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.

v Make sure that you have an adequate number of properly grounded electrical

outlets for the server, monitor, and other devices.

v Back up all important data before you make changes to disk drives. v Have a small flat-blade screwdriver, a small Phillips screwdriver, and a T8 torx

screwdriver available.

v You do not have to turn off the server to install or replace hot-swap power

supplies, hot-swap fans, or hot-plug Universal Serial Bus (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 riser card.

v Blue on a component indicates touch points, where you can grip the component

to remove it from or install it in the server, open or close a latch, and so on.

v Orange on a component or an orange label on or near a component indicates

that the component can be hot-swapped, which means that if the server and operating system support hot-swap capability, you can remove or install the component while the server is 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.

v When you are finished working on the server, reinstall all safety shields, guards,

labels, and ground wires.

System reliability guidelines

To help ensure proper system cooling and system reliability, make sure that the following requirements are met.

To help ensure proper system cooling and system reliability, make sure that the following requirements are met:

v Each of the drive bays has a drive or a filler panel and electromagnetic

compatibility (EMC) shield installed in it.

v If the server has redundant power, each of the power-supply bays has a power

supply installed in it.

v There is adequate space around the server to allow the 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 objects in front of the fans. For proper cooling and airflow, replace the server cover before you turn on the server.

v You have followed the cabling instructions that come with optional adapters. v You have replaced a failed fan within 48 hours. v You have replaced a hot-swap fan within 30 seconds of removal. v You have replaced a hot-swap drive within 2 minutes of removal. v You do not operate the server without the air baffle installed. Operating the

server without the air baffle might cause the microprocessor to overheat.

v Microprocessor socket 2 always contains either a microprocessor baffle or a

microprocessor and heat sink.

v You have installed the sixth fan when you installed the second microprocessor

option.

Working inside the server with the power on

Use this information when working inside the server with the power on.

Attention: Static electricity that is released to internal server components when the server is powered-on might cause the server to halt, which might result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when you work inside the server with the power on.

The server supports hot-plug, hot-add, and hot-swap devices and is designed to operate safely while it is turned on and the server cover is removed. Follow these guidelines when you work inside a server that is turned on:

v Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved

shirts before working inside the server; do not wear cuff links while you are working inside the server.

v Do not allow your necktie or scarf to hang inside the server. v Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist

watches.

v Remove items from your shirt pocket, such as pens and pencils, that could fall

into the server as you lean over it.

v Avoid dropping any metallic objects, such as paper clips, hairpins, and screws,

into the server.

Chapter 2. Installing optional devices 45

Handling static-sensitive devices

Use this information to handle static-sensitive devices.

Attention: Static electricity can damage the server and other electronic devices. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

To reduce the possibility of damage from electrostatic discharge, observe the following precautions:

v Limit your movement. Movement can cause static electricity to build up around

you.

v The use of a grounding system is recommended. For example, wear an

electrostatic-discharge wrist strap, if one is available. Always use an electrostatic-discharge wrist strap or other grounding system when working inside the server with the power on.

v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed circuitry. v Do not leave the device where others can handle and damage it. v 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 2 seconds. This drains static electricity from the package and from your body.

v Remove the device from its package and install it directly into the server

without setting down the device. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device on the server cover or on a metal surface.

v Take additional care when handling devices during cold weather. Heating

reduces indoor humidity and increases static electricity.

Installing a memory module

The following notes describe the types of DIMMs that the server supports and other information that you must consider when you install DIMMs.

v When you install or remove DIMMs, the server configuration information

changes. When you restart the server, the system displays a message that indicates that the memory configuration has changed.

v The server supports only industry-standard double-data-rate 3 (DDR3), 800,

1066, or 1333 MHz, PC3-10600R-999, registered or unbuffered, synchronous dynamic random-access memory (SDRAM) dual inline memory modules (DIMMs) with error correcting code (ECC). See http://www.ibm.com/ supportportal/for a list of supported memory modules for the server.

– The specifications of a DDR3 DIMM are on a label on the DIMM, in the

following format. ggg eRxff-PC3-wwwwwm-aa-bb-cc where:

- ggg is the total capacity of the DIMM (for example, 1GB, 2GB, or 4GB)

- e is the number of ranks 1 = single-rank 2 = dual-rank 4 = quad-rank

- ff is the device organization (bit width) 4 = x4 organization (4 DQ lines per SDRAM) 8 = x8 organization 16 = x16 organization

- wwwww is the DIMM bandwidth, in MBps 6400 = 6.40 GBps (PC3-800 SDRAMs, 8-byte primary data bus) 8500 = 8.53 GBps (PC3-1066 SDRAMs, 8-byte primary data bus) 10600 = 10.66 GBps (PC3-1333 SDRAMs, 8-byte primary data bus) 12800 = 12.80 GBps (PC3-1600 SDRAMs, 8-byte primary data bus)

Baffle tab

54 IBM System x3550 M3 Type 4254 and 7944: Installation and User's Guide

- m is the DIMM type E = Unbuffered DIMM (UDIMM) with ECC (x72-bit module data bus) R = Registered DIMM (RDIMM) U = Unbuffered DIMM with no ECC (x64-bit primary data bus)

- aa is the CAS latency, in clocks at maximum operating frequency

- bb is the JEDEC SPD Revision Encoding and Additions level

- cc is the reference design file for the design of the DIMM

- d is the revision number of the reference design of the DIMM

Note: To determine the type of a DIMM, see the label on the DIMM. The information on the label is in the format xxxxx nRxxx PC3-xxxxx-xx-xx-xxx. The numeral in the sixth numerical position indicates whether the DIMM is single-rank (n=1), dual-rank (n=2), or quad-rank (n=4).

v The following rules apply to DDR3 DIMM speed as it relates to the number of

DIMMs in a channel: – When you install 1 DIMM per channel, the memory runs at 1333 MHz – When you install 2 DIMMs per channel, the memory runs at 1066 MHz – When you install 3 DIMMs per channel, the memory runs at 800 MHz – All channels in a server run at the fastest common frequency – Do not install registered and unbuffered DIMMs in the same server

v The maximum memory speed is determined by the combination of the

microprocessor, DIMM speed, and the number of DIMMs installed in each channel.

v In two-DIMM-per-channel configuration, a server with an Intel Xeon X5600

series microprocessor automatically operates with a maximum memory speed of up to 1333 MHz when one of the following conditions is met:

– Two 1.5 V single-rank or dual-rank RDIMMs are installed in the same

channel. In the Setup utility, Memory speed is set to Max performance mode

– Two 1.35 V single-rank or dual-ranl RDIMMs are installed in the same

channel. In the Setup utility, Memory speed is set to Max performance and LV-DIMM power is set to Enhance performance mode. The 1.35 V RDIMMs will function at 1.5 V

v The server supports a maximum of 18 single-rank or dual-rank RDIMMs. The

server supports up to 12 single-rank or dual-rank UDIMMs or quad-rank RDIMMs.

v The server supports three single-rank or dual-rank DIMMs per channel. The

server supports a maximum of two quad-rank RDIMMs per channel. The following table shows an example of the maximum amount of memory that you can install using ranked DIMMs:

v The RDIMM options that are available for the server are 2 GB, 4 GB, 8 GB, and

16 GB. The server supports a minimum of 2 GB and a maximum of 288 GB of system memory using RDIMMs.

For 32-bit operating systems only: Some memory is reserved for various system resources and is unavailable to the operating system. The amount of memory that is reserved for system resources depends on the operating system, the configuration of the server, and the configured PCI devices.

v The UDIMM options that are available for the server are 2 GB and 4 GB. The

server supports a minimum of 2 GB and a maximum of 48 GB of system memory using UDIMMs.

Note: The amount of usable memory is reduced depending on the system configuration. A certain amount of memory must be reserved for system resources. To view the total amount of installed memory and the amount of configured memory, run the Setup utility. For additional information, see Chapter 3, “Configuring the server,” on page 111.

v A minimum of one DIMM must be installed for each microprocessor. For

example, you must install a minimum of two DIMMs if the server has two microprocessors installed. However, to improve system performance, install a minimum of three DIMMs for each microprocessor.

v DIMMs in the same channel must be the same type (RDIMM or UDIMM) to

ensure that the server will operate correctly.

v When you install one quad-rank RDIMM in a channel, install it in the DIMM

connector furthest away from the microprocessor.

Chapter 2. Installing optional devices 57

Memory mirroring

Memory-mirroring mode replicates and stores data on two pairs of DIMMs within two channels simultaneously. If a failure occurs, the memory controller switches from the primary pair of memory DIMMs to the backup pair of DIMMs.

To enable memory mirroring through the Setup utility, select System Settings > Memory. For more information, see “Using the Setup utility” on page 112. When you use the memory mirroring feature, consider the following information:

v When you use memory mirroring, you must install a pair of DIMMs at a time.

One DIMM must be in channel 0, and the mirroring DIMM must be in the same slot in channel 1. The two DIMMs in each pair must be identical in size, type, and rank (single or dual), and organization, but not in speed. The channels run at the speed of the slowest DIMM in any of the channels.

v Channel 2, DIMM connectors 7, 8, 9, 16, 17, and 18 are not used in

memory-mirroring mode.

v The maximum available memory is reduced to half of the installed memory

when memory mirroring is enabled. For example, if you install 64 GB of memory using RDIMMs, only 32 GB of addressable memory is available when you use memory mirroring.

The following diagram shows the memory channel interface layout with the DIMM installation sequence for mirroring mode. The numbers within the boxes indicate the DIMM population sequence in pairs within the channels, and the numbers next to the boxes indicate the DIMM connectors within the channels. For example, the following illustration shows the first pair of DIMMs (indicated by ones (1) inside the boxes) should be installed in DIMM connectors 1 on channel 0 and DIMM connector 2 on channel 1. DIMM connectors 3, 6, 9, 12, 15, and 18 on channel 2 are not used in memory-mirroring mode.

The following illustration shows the memory connector layout that is associated with each microprocessor. For example, DIMM connectors 10, 11, 12, 13, 14, 15, 16, 17, and 18 (DIMM connectors are shown underneath the boxes) are associated with microprocessor 2 (CPU2) and DIMM connectors 1, 2, 3, 4, 5, 6, 7, 8, and 9 are associated with microprocessor 1 (CPU1). The numbers within the boxes indicate the installation sequence of the DIMM pairs. For example, the first DIMM pair (indicated within the boxes by ones (1)) should be installed in DIMM connectors 1 and 2, which is associated with microprocessor 1 (CPU1).

Installing a hot-swap ac power supply

Use this information to install a hot-swap ac power supply.

About this task

The following notes describe the type of ac power supply that the server supports and other information that you must consider when you install a power supply:

v Make sure that the devices that you are installing are supported. For a list of

supported optional devices for the server, see http://www.ibm.com/systems/ info/x86servers/serverproven/compat/us/.

v Before you install an additional power supply or replace a power supply with

one of a different wattage, you may use the IBM Power Configurator utility to determine current system power consumption. For more information and to download the utility, go to http://www.ibm.com/systems/bladecenter/ resources/powerconfig.html.

v The server comes with one hot-swap 12-volt output power supply that connects

to power supply bay 1. The input voltage is 110 V ac or 220 V ac auto-sensing.

v You cannot mix 460-watt and 675-watt power supplies, high-efficiency and

non-high-efficiency power supplies, or ac and dc power supplies in the server.

v The following information applies when you install 460-watt power supplies in

the server: – A warning message is generated if the total power consumption exceeds 400

watts and the server only has one operational 460-watt power supply. In this case, the server can still operate under normal condition. Before you install additional components in the server, you must install an additional power supply

– The server automatically shuts down if the total power consumption exceeds

the total power supply output capacity

– You can enable the power capping feature in the Setup utility to control and

monitor power consumption in the server (see “Setup utility menu choices” on page 113)

The following table shows the system status when you install 460-watt power supplies in the server:

Table 15. System status with 460-watt power supplies installed
