The server diagnostic programs are stored in upgradable read-only memory (ROM)

the system board. These programs are the primary method of testing the major components of a server. Major components that can be tested include the system board, Ethernet controller, video controller, RAM, keyboard, mouse (pointing device), diskette drive, serial ports, hard drives, and parallel port. Not all servers include all of these items; your hardware might differ. You can also use the diagnostic programs to test some external devices. See “Diagnostic programs and error messages” on page 15.

you cannot determine whether a problem is caused by the hardware or by the software, you can run the diagnostic programs to confirm that the hardware is working properly.

When you run the diagnostic programs, a single problem might cause several error messages. When this occurs, work to correct the cause of the first error message. After the cause of the first error message is corrected, the other error messages might not occur the next time you run the test.

failed server might be part of a shared DASD cluster (two or more servers sharing the same external storage device(s)). Prior to running diagnostics, verify that the failing server is not part of a shared DASD cluster.

server might be part of a cluster if:

The customer identifies the server as part of a cluster. One or more external storage units are attached to the server and at least one of

the attached storage units is additionally attached to another server or unidentifiable source.

One or more servers are located near the failing server.

the failing server is suspected to be part of a shared DASD cluster, all diagnostic tests can be run except diagnostic tests which test the storage unit (DASD residing

the storage unit) or the storage adapter attached to the storage unit.

Notes:

For servers that are part of a shared DASD cluster, run one test at a time in looped mode. Do not run all tests in looped mode, as this could enable the DASD diagnostic tests.

multiple error codes are displayed, diagnose the first error code displayed. the server stops working with a POST error, go to “Symptom-to-FRU index”

page 115.

the server stops working and no error is displayed, go to “Undetermined

problems” on page 143.

For information about power supply problems, see “Power supply LED errors”

page 133. For safety information, see “Safety information” on page 145. For intermittent problems, check the error log; see “Error logs” on page 14.

001 IS THE SERVER PART OF A CLUSTER?

YES. Schedule maintenance with the customer. Shut down all servers

related to the cluster. Run storage test. NO. Go to step 002.

002 IF THE SERVER IS NOT PART OF A CLUSTER:

Turn off the server and all external devices. Check all cables and power cords. Set all display controls to the middle position. Turn on all external devices. Turn on the server. Record any POST error messages displayed on the screen. If an error is displayed, look up the first error in the “POST error codes” on page 134. Check the diagnostic LED panel system error LED; if on, see “Level 2 Light Path Diagnostics” on page 19. Check the System Error Log. If the server recorded an error, see “Symptom-to-FRU index” on page 115. Start the diagnostic programs. See “Diagnostic programs and error messages” on page 15. Check for the following responses:

One beep. Readable instructions or the Main Menu.

003

DID YOU RECEIVE BOTH OF THE CORRECT RESPONSES? NO. Find the failure symptom in “Symptom-to-FRU index” on page 115. YES. Run the diagnostic programs. If necessary, see “Diagnostic programs

and error messages” on page 15.

What the xSeries 360 offers

The design of the server takes advantage of advancements in symmetric multiprocessing (SMP), data storage, disk-array technologies, and memory management. The server combines:

X-Architecture technology X-Architecture technology is an IBM design blueprint that takes full advantage of

existing IBM technologies to build powerful, scalable, and reliable Intel processor-based servers.

For more information about X-Architecture technology, go to the Web at http://www.pc.ibm.com/us/eserver/xseries/xarchitecture/index.html.

Impressive performance using an innovative approach to SMP The server supports up to four Intel Xeon Processor MP

server comes with at least one microprocessor installed; you can install additional processors to enhance performance and provide SMP capability.

Large data-storage and hot-swap capabilities The xSeries 360 server supports up to three 26 mm (1-inch) slim-high 3.5-inch

hot-swap hard disk drives in the hot-swap bays. This hot-swap feature enables you to remove and replace hard disk drives without turning off the server.

Active PCI-X (hot-plug) adapter capabilities The server has six hot-plug PCI-X slots for PCI or PCI-X adapters. With

operating-system support, you can replace failing hot-plug PCI/PCI-X adapters without turning off the server. If the hot-add feature is supported by both the operating system and a PCI/PCI-X adapter, you can also add such PCI/PCI-X adapters in these slots without turning off the server.

Redundant hot-swap cooling and redundant hot-swap power capabilities The fans in the server can operate at variable speeds so that if one fan fails, the

remaining fans increase in speed to enable continued operation until the failing fan is replaced. You can replace a failing fan without turning off the server.

The server supports up to three 370-watt power supplies. Multiple hot-swap 370-watt power supplies ensure redundancy and hot-swap capability for a typical configuration.

Large system memory The memory bus in the server supports up to 8 GB of system memory. The

memory controller provides error correcting code (ECC) support for up to eight industry-standard, 2.5 V, 168-pin, 16-byte, PC1600 registered DDR SDRAM dual inline memory modules (DIMMs). The memory controller also provides Chipkill Memory protection. Chipkill Memory protection is a technology that protects the server from a single chip failure on a DIMM.

Light Path Diagnostics Light Path Diagnostics provide LEDs to assist in isolating problems with the

server. An LED on the operator information panel is lit if an unusual condition or

problem occurs. If this happens, you can look at the LEDs visible through a special cutout in the cover and isolate the cause. Under some circumstances, you might need to remove the cover and view LEDs on the system board to pinpoint the source of a problem.

Systems-management capabilities The server comes with a Remote Supervisor Adapter installed. This adapter, in

conjunction with the systems-management software provided with the server, enables you to manage the functions of the server both locally and remotely. The Remote Supervisor Adapter also provides system monitoring, event recording, and dial-out alert capability.

Integrated network environment support The server comes with an Ethernet controller integrated into the system board.

This Ethernet controller has an interface for connecting to 10-Mbps or 100-Mbps networks. The server automatically selects between 10BASE-T and 100BASE-TX. The controller provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN).

Remote expansion enclosure The addition of an optional, IBM RXE-100 Remote Expansion Enclosure provides

twelve additional hot-plug PCI/PCI-X slots for PCI or PCI-X adapters. The enclosure can be managed through the Remote Supervisor Adapter, enabling remote operation over a network or a modem.

Redundant network adapter The addition of an optional, redundant network adapter provides a failover

capability to a secondary Ethernet connection. If a problem occurs with the primary Ethernet connection, all Ethernet traffic associated with this primary connection is automatically switched to the redundant network adapter. If the appropriate device drivers are installed, this switching occurs without data loss and without user intervention.

POST

When you turn on the server, it performs a series of tests to check the operation of server components and some of the options that are installed in the server. This series of tests is called the power-on self-test, or POST.

POST finishes without detecting any problems, a single beep sounds, and the first

screen of the operating system or application program appears.

POST detects a problem, more than one beep sounds, and an error message

appears on the screen. See “Beep symptoms” on page 115 and “POST error codes”

page 134 for more information.

Notes:

you have a power-on password or administrator password set, you must type

the password and press Enter, when prompted, before POST will continue.

This causes the LED on the operator information panel to blink, reminding you that you need to take action. The remind function enables normal operations to continue, possibly using redundant components, until reduced server activity allows you to correct the problem. The LED for the component causing the problem stays lit until you make repairs.

Power problems can be difficult to troubleshoot. For instance, a short circuit can exist anywhere on any of the power distribution busses. Usually a short circuit will cause the power subsystem to shut down because of an overcurrent condition.

general procedure for troubleshooting power problems is as follows:

Power off the system and disconnect the AC cord(s). Check for loose cables in the power subsystem. Also check for short circuits, for

instance if there is a loose screw causing a short circuit on a circuit board. Remove adapters and disconnect the cables and power connectors to all

internal and external devices until system is at minimum configuration required for power on (see “Undetermined problems” on page 143 for a description of the minimum operating requirements).

Reconnect the AC cord and power on the system. If the system powers up successfully, replace adapters and devices one at a time until the problem is isolated. If system does not power up from minimal configuration, replace FRUs

minimal configuration one at a time until the problem is isolated.

use this method it is important to know the minimum configuration required for a system to power up (see “Undetermined problems” on page 143 for a description of the minimum operating requirements). For specific problems, see “Power error messages” on page 140.

If you directly connect two workstations (without a hub), or if you are not using a hub with X ports, use a crossover cable.

Note: To determine whether a hub has an X port, check the port label. If the

label contains an X, the hub has an X port. Determine if the hub supports auto-negotiation. If not, try configuring the integrated Ethernet controller manually to match the speed and duplex mode of the hub. Check the Ethernet controller lights on the server rear panel.

These lights indicate whether a problem exists with the connector, cable, or hub.

The Ethernet Link Status light illuminates when the Ethernet controller receives a LINK pulse from the hub. If the light is off, there might be a defective connector or cable, or a problem with the hub. The Ethernet Transmit/Receive Activity light illuminates when the Ethernet controller sends or receives data over the Ethernet Network. If the Ethernet Transmit/Receive Activity light is off, make sure that the hub and network are operating and that the correct device drivers are loaded.

Check the LAN activity light (if available) on the rear of the server. The LAN

activity light is illuminated when data is active on the Ethernet network. If the LAN activity light is off, make sure that the hub and network are operating and that the correct device drivers are loaded. Make sure that you are using the correct device drivers, which are supplied with the server. Check for operating-system-specific causes for the problem. Make sure that the device drivers on the client and server are using the same protocol. Test the Ethernet controller.

The way you test the Ethernet controller depends on which operating system you are using (see the Ethernet controller device driver README file).

The Ethernet wrap test can be used to determine if a hardware problem is causing the Ethernet connection to fail. To perform the Ethernet wrap test, use the wrap plug (FRU # 60G3981) in conjunction with the diagnostic tests.

the testing methods above indicate that the hardware is functioning normally

but the problem still exists, inform the network administrator.

ServeRAID configuration program

ServeRAID adapter enables you to use multiple physical SCSI hard-disk drives as logical drives, operating as a disk array. To enable you to configure the ServeRAID controller, the adapter comes with a CD containing the ServeRAID Manager program and the ServeRAID Mini-Configuration program. For details about using these programs, see the documentation that comes with the ServeRAID adapter.

Configuring the Ethernet controller

The server comes with an integrated Ethernet controller. This controller provides an interface for connecting to 10-Mbps or 100-Mbps networks and provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN).

use the Ethernet port, connect an appropriate (Category 5 is recommended) unshielded twisted-pair (UTP) cable to the RJ-45 connector on the rear of the server.

Note: The 100BASE-TX Fast Ethernet standard requires that the cabling in the

network be Category 5 or higher.

The Ethernet (RJ-45) connectors on the rear panel and on the Remote Service Adapter each have two lights. When the green Ethernet link-status light is on, there

active connection on the Ethernet port. When the amber Ethernet transmit/receive activity light is on, there is activity between the server and the network. For a description of the Ethernet port, see “Ethernet port” on page 100.

When you connect the server to the network, the Ethernet controller automatically detects the data-transfer rate (10 Mbps or 100 Mbps) on the network and then sets the controller to operate at the appropriate rate. In addition, if the Ethernet port that the server is connected to supports auto-negotiation, the Ethernet controller will set the appropriate duplex state. That is, the Ethernet controller will adjust to the network data rate, whether the data rate is standard Ethernet (10BASE-T), Fast Ethernet (100BASE-TX), half duplex (HDX), or full duplex (FDX). The controller supports half-duplex (HDX) and full-duplex (FDX) modes at both speeds.

Configuration

Page 48

The Ethernet controller is a PCI Plug and Play device. You do not need to set any jumpers or configure the controller for the operating system before you use the controller. However, you must install a device driver to enable the operating system

access the controller. The device driver is provided on the ServerGuide CDs.

you install an optional Ethernet adapter, you can use it together with the integrated Ethernet controller to support optional modes, such as teaming, priority packets, and virtual LANs, which provide higher performance and throughput for the server. These modes apply to the integrated Ethernet controller and to the controllers on the supported Ethernet adapters.

Remote Supervisor Adapter

This section identifies the Remote Supervisor Adapter features, prerequisites, and recommendations. It also explains how to use the documentation effectively and how to cable and configure the adapter for use on an Advanced System Management (ASM) network so that you can manage the server from a remote location. For more detailed information see the Remote Supervisor Adapter User’s

Guide on the Documentation CD.

Remote Supervisor Adapter features

Using the ASM interconnect network

This section explains how to configure and connect the server to function within an ASM interconnect network.

The ASM interconnect network can include as many as 12 individual ASM connections in a single bus. These connections can include Remote Supervisor Adapters, ASM processors, and ASM PCI Adapters. When the clients and servers are connected, they use the ASM interconnect network to share ASM resources, information, and alerts among multiple servers, without having to add additional communications hardware or network interface adapters.

ASM interconnect network provides two levels of functionality. First, the ASM

interconnect network enables you to configure settings and to control the servers

Hardware Maintenance Manual: xSeries 360 Type 8686

Page 61

v It is

where other Remote Supervisor Adapters, ASM processors, and ASM PCI Adapters

the network reside. Second, the ASM interconnect network enables other interconnect network devices to use the resources (Ethernet or modem) of other Remote Supervisor Adapters, ASM processors, and ASM PCI Adapters in the ASM interconnect network for sending alerts. This interconnect network is used when Remote Supervisor Adapters, ASM processors, or ASM PCI Adapters cannot send

alert and must forward the information to another one of these devices to send the alert.

Planning and cabling the interconnect network

support the most recent ASM features, a Remote Supervisor Adapter must be the main gateway interconnect to the ASM interconnect bus if the bus also includes servers with ASM PCI adapters or ASM processors. The Remote Supervisor Adapter forwards the ASM information generated by the servers attached to the ASM interconnect bus to other servers on the Ethernet network. The connected ASM processors and ASM PCI Adapters are managed through the new user interface and Web browser access of the Remote Supervisor Adapter.

Note: To ensure the stability of the system, you must have the most current level of

firmware installed on the Remote Supervisor Adapter that is the main interconnect gateway for the ASM interconnect network. The most current level of firmware is available on the World Wide Web at http://www.ibm.com/support.

You must connect an ASM Interconnect module to the Remote Supervisor Adapter and to each server that you connect to the ASM interconnect network bus.

Attention: To avoid damage to the Ethernet connector on the Remote Supervisor

Adapter, do not plug the ASM Interconnect module into the Remote Supervisor Adapter Ethernet port.

connect the servers, note the following setup and configuration considerations:

Make sure that the ASM interconnect network is set up as a bus, not as a ring. You must connect the servers to the ASM interconnect network in a series, with terminated beginning and end points.

Make sure that the total combined length of all Ethernet cables connecting the

server in the ASM interconnect network does not exceed 91 M (300 ft). Each Remote Supervisor Adapter, ASM PCI adapter, or ASM processor that is

connected to the ASM interconnect network bus counts as one connection. For example, if an ASM PCI adapter is installed in a server that has an ASM processor, the processor and the adapter connect to each other using one ASM interconnect connection, but the processor and the adapter count as two connections on the ASM interconnect network bus.

advisable that the most current level of firmware is installed on the Remote Supervisor Adapter that is the gateway for the interconnect network. For more information on updating firmware, see the Remote Supervisor Adapter User’s

Guide for the Eserver xSeries 360 on the Documentation CD.

Forwarding alerts

Remote Supervisor Adapters, ASM PCI adapters, and ASM processors that are connected to an ASM interconnect network share resources and system-management information. This section provides information on how alerts are forwarded in the ASM interconnect network.

Configuration

Page 62

During normal operation, each Remote Supervisor Adapter, ASM processor, or ASM PCI adapter on the ASM interconnect network communicates with the other processors and adapters on the network. Processors or adapters that have a modem or Ethernet connection notify the other processors and adapters that these communications resources are available for use by other servers on the ASM interconnect network. These resources are then used as ASM interconnect network resources, enabling Remote Supervisor Adapters, ASM processors, or ASM PCI adapters on the ASM interconnect network to send alerts using a modem or the network, even if they do not have a modem or network connection physically attached.

When alerts are generated, they are forwarded to the Remote Supervisor Adapter, ASM processor, or ASM PCI adapter on the ASM interconnect network that has the communication resources to forward the alert. If no system on the ASM interconnect network meets the requirements, the alert is set for transmission if the connection type is configured or becomes available later.

multiple modems or network connections exist in the ASM interconnect network, you cannot specify which system will receive an alert or which will use its modem or network connection to forward the alert. If an alert is forwarded to a Remote Supervisor Adapter, ASM processor, or ASM PCI adapter that is unable to deliver the alert (for example, the modem it is configured to use has failed or the network cannot resolve the destination IP address), the processor or adapter attempts to forward the alert to another system on the ASM interconnect network that has the communication resources to forward the alert.

Alerts are typically sent only once (per connection type), but an alert is forwarded to another interconnect device if the resources exist on other interconnect devices in the network. For example, on a three ASM processor network where ASM processor 1 generates a modem alert, but does not have a modem and the other ASM processors have modems, the following might occur:

ASM processor 1 generates an alert and the modem is unplugged from ASM processor 2 45 seconds prior to ASM processor 1 generating the alert, ASM processor 1 forwards the alert to ASM processor 2, having previously determined that ASM processor 2 has an available modem. When ASM processor 2 receives the forwarded alert, it determines that a modem is attached to ASM processor 3, and forwards the alert. Therefore, depending upon the time frame (45 seconds) within which a resource (modem) fails, the alert might be forwarded multiple times until an interconnect device can send the alert.

Cabling for the ASM interconnect network

Depending upon the servers you have, you might need additional ASM Interconnect modules or appropriate Ethernet cables (Category 5 recommended). Table 6 lists some IBM Netfinity and IBM xSeries products, and indicates whether you need to use an ASM Interconnect module to set up the ASM interconnect network.

System Updates and Applications

Creates diagnostic, RAID, device driver, and other support diskettes from the CD; or with an Internet connection, you can check for an update from a dedicated IBM file transfer protocol (FTP) server. Installs some updates without requiring diskettes. Where applicable, you can run executable files directly from the CD or unzip files to any drive on the server or another server on the network.

Includes a vast library of fully tested device drivers for the server. Includes a search function to help you locate updates by title or keywords. Installs powerful applications directly from the CD. See the CD label for a current list of applications.

Setup and configuration overview

When you use the Setup and Installation CD, you do not need setup diskettes. You can use the CD to configure any supported IBM server model. The setup program checks the system BIOS code, Remote Supervisor Adapter, and other system hardware to determine whether system updates are available. The setup program provides a list of tasks that are required to set up the server model. On RAID servers, you can run the ServeRAID Manager program to create logical drives.

Note: Specific features and functions can vary with different versions of the

ServerGuide software.

When you start the Setup and Installation CD:

You are prompted for the language, country, and keyboard layout. (This information is stored and later passed on to the NOS installation program.)

The ServerGuide program displays choices for running the configuration programs. For example:

The Express Configuration method runs the required programs for the server, based on the hardware that is detected.

The Custom Configuration method displays all programs that are available for the server, and you decide which programs to run.

The Replicated Configuration method provides the option of duplicating your setup selections to other servers that are the same model.

you select the Custom Configuration method, the following programs are

optional. If you select the Express Configuration method, some or all of these programs are run, depending on the hardware that is detected.

The Set Date and Time feature is provided so that you do not have to use the Configuration/Setup Utility program to access these settings.

The Clear Hard Disks program is provided so that you can delete all partitions

all hard disk drives. If the server has a ServeRAID adapter installed, you can select to restore the configuration on the ServeRAID adapter to the factory default settings.

The ServerGuide program checks the server BIOS code and microcode (firmware) levels for supported options and then checks the CD for a newer level. CD content can be newer than the hardware. The ServerGuide program can perform a flash update of the BIOS code and supported microcode (firmware) options without the use of diskettes.

The ServeRAID program starts, guiding you through the entire configuration process.

The Performance Optimizer program easily tunes the server for your environment.

The ServerGuide program creates a System Partition on the default drive.

The ServerGuide program displays a confirmation summary, so that you will

know when you have completed all the required tasks. Then, you are ready to install the NOS.

Notes:

Plug and Play adapters are configured automatically. Non-Plug and Play adapters or non-IBM adapters might require switch settings, additional device drivers, and installation after the NOS is installed. See the documentation that comes with the adapter.

Diagnostics for the server come in BIOS code or on a separate diagnostics CD.

System partition

The ServerGuide program creates a 50 MB system partition on the default drive. The System Partition contains server-specific utility programs such as Remote Supervisor Adapter disk operating system (DOS) utilities, system diagnostics, flash BIOS updates, and other programs.

Note: Programs in the System Partition vary by server model, and not all server

models run utility programs from the System Partition. To determine which ones do, start the Setup and Installation CD and view the online Overview.

After setup is complete, you can access programs in the System Partition by restarting the server and pressing Alt+F1 when the prompt is displayed. The System Partition menu displays the programs that are available on the server model.

Typical NOS Installation

You can use the ServerGuide program to shorten the installation time. The ServerGuide program provides the necessary device drivers, based on the hardware that you have and the NOS that you are installing. If you prefer to install the NOS without using ServerGuide, go to “Installing the NOS without ServerGuide”

page 61 for details.) The following is a brief explanation of a typical ServerGuide

NOS installation.

Note: Specific features and functions can vary with different versions of the

ServerGuide software

After you have completed the setup process, the operating system installation program starts. (You will need a copy of the NOS CD to complete the installation.)

The ServerGuide program stores information about the server model, Remote Supervisor Adapter, hard disk controllers, and network adapters. It then checks the CD for newer device drivers. This information is stored and then passed to the NOS installation program.

With some NOS installations, you can create a NOS Replication Diskette for setting up additional servers. The diskette will contain the Internet protocol (IP) address, server name, and other selections.

The ServerGuide program presents NOS partition options that are based on your NOS selection and the installed hard disk drives.

you are installing the NOS from diskette, the ServerGuide program displays the required diskettes that you must create, and the optional diskettes that you might want to create. The diskettes that you can create are the device driver diskettes for the installed adapters or controllers.

ServerGuide program prompts you to insert the NOS CD and restart the server.

The

this point, the installation program for the NOS takes control to complete the

installation.

Setting up or updating multiple servers

You can use the ServerGuide program to create diskettes that help you set up or update multiple servers. You can modify information on the diskettes as you use them to set up or update other servers.

If the operating system supports hot-plug PCI/PCI-X adapters, you can replace a failing hot-plug PCI/PCI-X adapter with a new adapter of the same type without turning off power to the server. If the operating system and adapter also support the hot-add feature, you can install a new adapter without turning off the power to the server.

Attention: Do not remove a hot-plug PCI/PCI-X adapter before determining

whether the operating system requires you to disable the hot-plug PCI-X slot that contains the adapter. Failing to disable the slot in this situation might cause the server to lock up. Refer to the operating-system documentation.

Adapter considerations

Before you install adapters, review the following:

Locate the documentation that comes with the adapter and follow those instructions in addition to the instructions in this chapter. If you need to change switch settings or jumper settings on the adapter, follow the instructions that come with the adapter.

Locate the documentation that comes with your operating system. If the operating system provides a way to disable or enable a PCI-X slot you will need this documentation.

you install a ServeRAID adapter for use with the internal hot-swap hard disk drives, you must connect the internal channel cable between the adapter and the SCSI RAID cable connector (J43) on the system board. However, if you do this, you cannot install a full-length, wide adapter in PCI-X slot 1.

The server supports only 3.3 V PCI or PCI-X adapters. The server uses a rotational interrupt technique to configure PCI/PCI-X adapters.

You can use this technique to install PCI/PCI-X adapters that currently do not support sharing of PCI interrupts.

PCI-X slots 3 through 6 are on PCI bus A; PCI-X slots 1 and 2 are on PCI bus B.

default, the server starts (boots) devices in the following order: system IDE

and SCSI devices, then PCI/PCI-X devices.

Note: To change the startup order, start the Configuration/Setup Utility program

and select Start Options from the main menu. Then, select the Startup

Sequence Options.

Hot-plug PCI/PCI-X adapter installation

This section describes how to install a hot-plug PCI/PCI-X adapter. Before you continue with the adapter-installation procedure, note that all six PCI-X slots support hot-plug, 64-bit, PCI/PCI-X adapters. If PCI/PCI-X adapters are installed in both slots 1 and 2, they operate at 100 MHz or less, depending on the capacity of the adapter. If one adapter is installed in slot 1 and slot 2 is empty, the adapter in slot 1 can operate at 133 MHz.

Each hot-swap hard disk drive has two indicator LEDs (see “Controls and indicators” on page 8). If the amber hard disk drive status LED for a drive is lit continuously, that individual drive is faulty and requires replacement. You can replace the hot-swap drive without turning off the server.

Each hot-swap drive that you plan to install must be mounted in a hot-swap-drive tray. The drive must have a single connector attachment (SCA) connector. Hot-swap-drive trays come with hot-swap drives.

Memory modules

The server supports up to four pairs of DIMMs and supports memory interleaving. Adding memory to the server is an easy way to make programs run faster.

Notes:

The server supports a minimum of 512 MB of system memory and a maximum

system memory. The DIMM slots are arranged in two columns of four rows each. The server supports DIMMs of 256 MB, 512 MB, and 1 GB capacities.

Each pair of DIMMs must be the same type, capacity, and speed. However, you can install DIMM pairs of different capacities as long as both DIMMs in each pair are the same.

Installing or removing DIMMs changes the configuration information in the server. Therefore, after installing or removing DIMMs, you must save the new configuration information using the Configuration/Setup Utility program. When you restart the server, the system displays a message indicating that the memory configuration has changed. Start the Configuration/Setup Utility program and select Save Settings. See “Configuration” on page 27 for more information.

Complete the following steps to install the DIMMs:

Microprocessor installation

The server comes with a minimum of one microprocessor installed on the system board and supports up to four microprocessors. With more than one microprocessor, the server can operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load among the microprocessors.

Before you begin:

Read the documentation that comes with the microprocessor to determine if you need to update the server basic input/output system (BIOS) code. The most current level of BIOS code for the server is available through the World Wide Web at http://www.ibm.com/pc/support.

Obtain an SMP-capable operating system (optional). For a list of supported operating systems, go to http://www.ibm.com/pc/us/compat/ on the World Wide Web.

Attention: To avoid damage and ensure proper server operation when you install

replacement or an additional microprocessor, use a microprocessor that has the

same cache size and type, clock speed, and internal and external clock frequencies

the microprocessors already installed.
