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 DSA program creates a chronologically ordered merge of the system-event

log (as the IPMI event log), the IMM event log (as the ASM event log), and the operating system logs. The information is collected into a file that you can send

Chapter 1. The System x3400 M2 server 9

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

v High-performance graphics controller

The server comes with an onboard high-performance graphics controller that supports high resolutions and includes many performance-enhancing features for the operating-system environment.

v IBM Systems Director CD

IBM Systems Director is a workgroup-hardware-management tool that you can use to centrally manage System x and xSeries servers. For more information, see the IBM Systems Director documentation on the IBM Systems Director CD and “IBM Systems Director” on page 13.

The ServerGuide Setup and Installation CD, which you can download from the Web, provides programs to help you set up the server and install a Windows operating system. The ServerGuide program detects installed optional hardware devices and provides the correct configuration programs and device drivers. For more information about the ServerGuide Setup and Installation CD, see “Using the ServerGuide Setup and Installation CD” on page 111.

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, or see http://www.ibm.com/ servers/systems/management/director/resources/.

v Integrated network support

The server comes with an integrated dual-port Broadcom Gigabit Ethernet controller, which supports connection to a 10 Mbps, 100 Mbps, or 1000 Mbps network. For more information, see “Configuring the Broadcom Gigabit Ethernet controller” on page 117.

v Integrated Trusted Platform Module (TPM)

This integrated security chip performs cryptographic functions and stores private and public secure keys. It provides the hardware support for the Trusted Computing Group (TCG) specification. You can download the software to support the TCG specification, when the software is available. See http://www.ibm.com/ servers/eserver/xseries/scalable_family.html for details about the TPM implementation. You can enable TPM support through the Setup utility under the System Security menu option.

v Large data-storage capacity and hot-swap capabilities

Some hot-swap server models support eight or sixteen (depending on your model) slim-high, 2.5-inch hot-swap hard disk drives or four 3.5-inch hot-swap

10 System x3400 M2 Types 7836 and 7837: Installation and User’s Guide

hard disk drives (depending on the model). With the hot-swap feature, you can add, remove, or replace hard disk drives without turning off the server.

v Large system-memory capacity

The server supports up to 96 GB (reduced to 48 GB in mirroring mode) of system memory. The memory controller supports error correcting code (ECC) for up to 12 industry-standard PC3-10600R-999 (single-rank or dual-rank), 800, 1067, and 1333 MHz, DDR3 (third-generation double-data-rate), registered, synchronous dynamic random access memory (SDRAM) dual inline memory modules (DIMMs).

v Memory mirroring

Some models support memory mirroring. Memory mirroring replicates and stores data on two pairs of DIMMs within two channels (channel 0 and 1) simultaneously. If a failure occurs, the memory controller switches from the primary pair of memory DIMMs to the backup pair of DIMMs. To support 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. For more information, see memory mirroring on page 47.

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. The optional RAID adapters are available for purchase and provide RAID levels 0, 1, 5, 6, 10, 50, and 60. See “Installing an adapter” on page 70 and “Using LSI Configuration Utility program” on page 117 for more information about the adapters that are supported and creating RAID arrays.

v Symmetric multiprocessing (SMP)

The server supports up to two Intel Xeon microprocessors. Each microprocessor provides symmetric multiprocessing capability. When you install the second microprocessor, this will enhance the performance of the server.

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 systems-management connector on the rear of the server is dedicated to the IMM. The dedicated systems-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 controller in the server supports 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. The Windows operating system requires that the Windows Scalable Network Pack (SNP) be installed for TOE support.

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

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. If the server is not working correctly, see the Problem Determination and Service Guide for diagnostic information.

32 System x3400 M2 Types 7836 and 7837: Installation and User’s Guide

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 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 fans and

hot-swap drives.

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 and 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 have to access the inside of the server, you might find it easier to lay

the server on its side.

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

labels, and ground wires.

v For a list of supported options for the server, see http://www.ibm.com/servers/

eserver/serverproven/compat/us/.

System reliability guidelines

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 turning on the server. Operating the server for extended periods of time (more than 30 minutes) with the server cover removed might damage server components.

v You have followed the cabling instructions that come with optional adapters.

Chapter 2. Installing optional devices 33

v You have replaced a failed fan as soon as possible. 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.

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 could result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when working inside the server with the power on.

The server (some models) supports hot-swap devices and is designed to operate safely while it is turned on and the 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

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.

Handling 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 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.

Attention: Do not mix UDIMMs and RDIMMs in the same server. v The server supports industry-standard, 800, 1066, or 1333 MHz,

PC3-10600R-999 (single-rank or dual-rank) double-data-rate 3 (DDR3), registered, synchronous dynamic random-access memory (SDRAM) dual inline memory modules (DIMMs) with error correcting code (ECC). For a list of supported options for the server, see http://www.ibm.com/servers/eserver/ serverproven/compat/us/; then, select your country and navigate to the list of options 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)

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

v The server supports a maximum of 12 single-rank or dual-rank DIMMs.

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) or dual-rank (n=2).

46 System x3400 M2 Types 7836 and 7837: Installation and User’s Guide

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

following table shows an example of the maximum amount of memory that you can install, using ranked DIMMs.

Table 6. Maximum memory installation using ranked DIMMs

Number of DIMMs DIMM type DIMM size Total memory

12 Single-rank DIMMs 4 GB 48 GB 12 Dual-rank DIMMs 4 GB 48 GB 12 Dual-rank DIMMs 8 GB 96 GB

v The DIMM options that are available for the server are 1 GB, 2 GB, 4 GB, and 8

GB. The server supports a minimum of 2 GB and a maximum of 96 GB of system memory.

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 “Using the Setup utility” on page 106.

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 The maximum operating speed of the server is determined by the slowest DIMM

install in the server.

v The server comes with a minimum of two 1 GB DIMMs, installed in slots 3 and 6. v When you install additional DIMMs in independent mode, install them in the order

shown in the following table to optimize system performance. All three channels on the memory interface for each microprocessor can be populated in any order and have no matching requirements.

Installed microprocessors DIMM connector population sequence

Microprocessor socket 1 3, 6, 8, 2, 5, 7 Microprocessor socket 2 11, 14, 16, 10, 13, 15 Note: DIMM connectors 1, 4, 9, and 12 are not functional. Do not install DIMMs in these

connectors.

v The server supports memory mirroring (mirroring mode):

– Memory-mirroring mode replicates and stores data on two pairs of DIMMs

within two channels (channels 0 and 1) 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 106. When you use the memory mirroring feature, consider the following information:

- 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.

Chapter 2. Installing optional devices 47

- Channel 2, DIMM connectors 7, 8, 15, and 16 are not used in memory-mirroring mode.

- The maximum available memory is reduced to half of the installed memory when memory mirroring is enabled. For example, if you install 48 GB of memory, only 24 GB of addressable memory is available when you use memory mirroring.

The following table lists the usable DIMM connectors on each memory channel.

Installing a hot-swap hard disk drive

Some server models come with hot-swap SAS or SATA hot-swap hard disk drives. Before you install a hot-swap hard disk drive, read the following information:

v The hot-swap drives must be either all SAS hard disk drives or all SATA hard

disk drives; do not mix SAS and SATA drives in the server.

v The hot-swap hard disk drive models come with the following drives (depending

on your model): – Four 3.5-inch hot-swap SAS or SATA hard disk drives – Eight or sixteen 2.5-inch hot-swap SAS or SATA hard disk drives

v The sequence for installing the 3.5-inch hard disk drives in the four-bay models is

to install the drives starting from the left bay (bay 4) and go to the right bay (bay

7) in that order.

v The sequence for installing the 2.5-inch hard disk drives in the eight-bay models

is to install the drives starting from the right bay (bay 4) and go to the left bay (bay 11) in that order.

v The hot-swap drives are arranged horizontally in the standard hard disk drive

cage; the drive numbers are 0 through 7 (right to left) on models with eight hard disk drives and 8 through 15 (right to left) on servers with 16 hard disk drives. When you install hard disk drives, start with drive 0.

v Inspect the drive tray for signs of damage. v Make sure that the drive is correctly installed in the tray. v You do not have to turn off the server to install hot-swap drives in the hot-swap

drive bays.

v All hot-swap drives must have the same throughput speed rating; mixing speed

ratings might cause all drives to operate at the lower throughput speed.

v The drive ID for each hot-swap hard disk drive is printed on the bezel. v To maintain proper system cooling, do not operate the server for more than 10

minutes without either a drive or a filler panel installed in each drive bay.

Power and signal cables for internal drives

The server uses cables to connect SATA attached, simple-swap SATA, hot-swap SATA and hot-swap SAS devices to the power supply and to the system board. (See “System-board internal connectors” on page 24 for the location of system-board connectors.) Review the following information before connecting power and signal cables to internal drives:

v The drives that are preinstalled in the server come with power and signal cables

attached. If you replace any drives, remember which cable is attached to which drive.

v When you route a cable, make sure that it does not block the airflow to the rear

of the drives or over the microprocessor or DIMMs.

The following cables are provided: v The DVD drive is attached to an ATA signal cable. The blue connector is

attached to the SATA 0 (optical drive connector) on the system board. The connector on the other end is attached to the SATA device. The middle connector attaches to an optional optical device or tape drive. A separate power cable provides power to the device from the system board.

v Simple-swap SATA models: The simple-swap SATA models come with a

combination signal/power cable that connects to the connector on the system board and the simple-swap SATA backplate to provide signal and power to the simple-swap SATA drives. Connect the power connector on the split end of the cable to the Hard disk drive backplane power connector (labeled A) on the system board and connect the signal connector on the split end of the cable to the Simple-swap SATA signal cable connector on the system board. The other end of the combination signal/power cable has a signal cable connected to each drive bay signal connector on the simple-swap SATA backplate and a power cable connected to each drive bay power connector on the simple-swap SATA backplate.

v Hot-swap SAS or hot-swap SATA models:

– The 2.5-inch hot-swap SAS and hot-swap SATA models come with the

following cables to provide signal and power to the hot-swap SAS/SATA drives:

- Four single signal cables (thick red and black) that connects to the signal cable connectors on the hard disk drive backplanes (the backplanes are labeled A0 and A1) and the connectors on the SAS/SATA RAID adapter (see the ServeRAID adapters installation instructions in this document for more cabling information).

- Two split power cables (red/yellow/black). The end of the power cable with the single connector connects to the Hard disk drive backplane power connector (the power connector labeled A) on the system board and the end of the power cable with the two connectors, connects to the power connectors on the hard disk drive backplanes (the backplanes are labeled A0 and A1).

- Two split configuration signal cables (black). The end of the configuration signal cable with the single connector connects to the Hard disk drive backplane configuration signal connector (the configuration connector labeled A) on the system board and the end of the configuration signal cable with the two connectors, connects to the configuration signal connectors on the hard disk drive backplanes (the backplanes are labeled A0 and A1).

Installing an adapter

The following notes describe the types of adapters that the server supports and other information that you must consider when installing an adapter. Adapter that the server supports might vary, depending on your server model.

v Locate the documentation that comes with the adapter and follow those

instructions in addition to the instructions in this section. If you must change the switch setting or jumper settings on the adapter, follow the instructions that come with the adapter.

v Read the documentation that comes with your operating system. v Use PCI slot 2 for video adapters. v Do not set the maximum digital video adapter resolution above 1600 x 1200 at

85 Hz for an LCD monitor. This is the highest resolution that is supported for any add-on video adapter that you install in the server.

v Any high-definition video-out connector or stereo connector on any add-on video

adapter is not supported

v The server provides up to eight adapter connectors, or slots as follows

(depending on your server model):

drive backplane and one of the connectors on the SAS/SATA RAID adapter (see the ServeRAID adapters installation instructions in this document for more cabling information).

drive backplane power connector (the power connector labeled A) on the system board and to the power connector on the hard disk drive backplane.

drive backplane configuration signal connector (the configuration connector labeled A) on the system board and the configuration signal connector on the hard disk drive backplane.

Note: The x8 (x4) designation for slot 3 (for example) identifies an x8 slot that is designed to support x8 adapters and x4 adapters that can downshift to operate at the x4 bandwidth. If you install an x8 adapter in slot 3 that can downshift to the x4 bandwidth, it will run at the x4 bandwidth. The x8 connector can be used for x4 and x8 adapters. These same rules apply to the other PCI slots also. Check the information that comes with your adapter for compatibility information.

– Slots on the system board:

- Slot 1, PCI Express Gen 2 x8 (x8)

- Slot 2, PCI Express Gen 2 x16 (x8)

- Slot 3, PCI Express Gen 2 x8 (x4)

- Slot 4, PCI Express Gen 2 x8 (x4)

- Slot 5, PCI Express Gen 2 x8 (x8)

70 System x3400 M2 Types 7836 and 7837: Installation and User’s Guide

- Slot 6, PCI 32-bit/33 MHz

– If you install the optional one-slot PCI extender card in the server:

- One additional PCI Express Gen 1 x8 (x4) slot is available

– If you install the optional two-slot PCI extender card in the server:

- Two additional PCI-X 32-bit/64-bit 133/100/66 MHz slots are available

v You can install full-length adapters that are included in the ServerProven

list in slots 2, 3, 4, and 5 on the system board, and the slots on the one-slot or two-slot extender cards. You can only install half-length adapters in slots 1 and 6.

v The 32-bit slot 6 supports 5.0 V keyed PCI adapters; they do not support 3.3 V

keyed adapters. Universal adapters are supported in slots 4 and 5 if they are universally keyed.

v You can install the IBM ServeRAID-BR10i SAS/SATA controller, the optional IBM

ServeRAID-MR10i SAS/SATA controller, or the optional IBM ServeRAID-MR10is VAULT SAS/SATA controller in slots 1 of hot-swap SAS or hot-swap SATA models. These ServeRAID adapters are not supported on the simple-swap models.

v The ServeRAID-BR10i adapter comes standard on hot-swap SAS and hot-swap

SATA models and provides RAID levels 0, 1, and 1E support. You can order the ServeRAID-MR10i adapter which provides RAID levels 0, 1, 5, 6, 10, 50, and 60 support, and the optional ServeRAID-MR10is adapter with an encryption 1078 DE chip provides RAID levels 0, 1, 5, 6, 10, 50, and 60 support.

To ensure that any of your ServeRAID 10i, 10is, or 10M adapters function properly on UEFI-based servers, make sure that the adapter firmware level is updated to at least 11.x.x-XXX , and the supporting drivers.

Attention: 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.

v The server scans PCI Express slot 1, PCI-X slots 4 and 5, and PCI-Express slots

2 and 3 to assign system resources. Then, the server starts the devices in the following order, if you have not changed the default startup sequence: PCI Express slot 1, PCI-X slots 4 and 5, PCI Express slot 2, PCI slot 6, and PCI Express slot 3.

v For a list of supported options for the server, see http://www.ibm.com/servers/

eserver/serverproven/compat/us/.

To install an adapter, complete the following steps:

Note: The instructions in this section apply to any PCI adapter (for example, video graphics adapters or network adapters).

Installing a second microprocessor

The following notes describe the type of microprocessor that the server supports and other information that you must consider when installing a microprocessor:

v The server comes with one microprocessor installed, but supports up to two

microprocessors.

Note: A microprocessor must be installed and removed only by a trained service technician.

v Read the documentation that comes with the microprocessor to determine

whether you have to update the server firmware. To download the most current level of the firmware for your server, go to http://www.ibm.com/systems/support/, and click Downloads and drivers.

v The first microprocessor must always be installed in microprocessor socket 1. v When one microprocessor is installed, a heat sink filler is not required for

microprocessor socket 2; however, the air baffle must be installed to provide proper system cooling.

v Do not remove the first microprocessor from the system board when you install

the second microprocessor.

v When you install the second microprocessor, you must also install additional

memory. See “Installing a memory module” on page 46.

v The first microprocessor voltage regulator module (VRM) is integrated on the

system board.

Chapter 2. Installing optional devices 73

v When you install a second microprocessor, you must also install the voltage

regulator module (VRM), which comes with the microprocessor option kit, in the VRM connector on the system board.

v Some models support dual-core microprocessors or quad-core microprocessors.

Do not mix dual-core microprocessors and quad-core microprocessors in the same system. Install all dual-core or all quad-core microprocessors in the server.

v To ensure proper server operation when you install an additional microprocessor,

use microprocessors that have the same QuickPath Interconnect (QPI) link speed, integrated memory controller frequency, core frequency, power segment, internal cache size, and type. You can use the Setup utility to determine the specific type of microprocessor that is installed on the system board.

v Mixing microprocessors of different stepping levels within the same server model

is supported. You do not have to install the microprocessor with the lowest stepping level and features in microprocessor socket 1.

v The microprocessor speeds are automatically set for this server; therefore, you

do not have to set any microprocessor frequency-selection jumpers or switches.

v If the thermal-grease protective cover (for example, a plastic cap or tape liner) is

removed from the heat sink, do not touch the thermal grease on the bottom of the heat sink or set down the heat sink.

v If you have to replace a microprocessor, call for service. v To order additional microprocessor options, contact your IBM marketing

representative or authorized reseller. See http://www.ibm.com/servers/eserver/ serverproven/compat/us/ for a list of supported microprocessors.
