General checkout

The server diagnostic programs are stored in upgradable read-only memory (ROM) on the system board. These programs are the primary method of testing the major components of the server: The system board, Ethernet controller, video controller, RAM, keyboard, mouse (pointing device), diskette drive, serial ports, hard drives, and parallel port. You can also use them to test some external devices. See “Diagnostic programs and error messages” on page 13

Also, if 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.

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

A system might be part of a cluster if:

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

of the attached storage units is additionally attached to another system or

unidentifiable source. v One or more systems are located near the failing system.

If the failing system 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 in the storage unit) or the storage adapter attached to the storage unit.

Notes:

1. For systems 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.

2. If multiple error codes are displayed, diagnose the first error code displayed.

3. If the computer hangs with a POST error, go to the “Symptom-to-FRU index” on

page 97

4. If the computer hangs and no error is displayed, go to “Undetermined problems”

on page 122

5. Power supply problems, see “Symptom-to-FRU index” on page 97

Server features

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

v Impressive performance using an innovative approach to SMP

The server supports up to four Pentium III Xeon processors. The server comes with at least one processor installed; you can install additional processors to enhance performance and provide SMP capability.

v Large data-storage and hot-swap capabilities

All models of the server support up to three standard and three optional 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.

v Active PCI (hot-plug) adapter capabilities

The server has six hot-plug slots for PCI adapters. With operating system support, you can replace failing hot-plug PCI adapters without turning off the server. If the hot-add feature is supported by the operating system and the PCI adapter, you can also add PCI adapters in these slots without turning off the server.

v Redundant cooling and power capabilities

The redundant cooling and hot-swap capabilities of the fans in the server enable continued operation if one of the fans fails. You can also replace a failing fan without turning off the server.

The server comes standard with one 270-watt power supply. Install three 270-watt power supplies to ensure redundancy and hot-swap capability for a typical configuration. (See “Installing a hot-swap power supply” on page 70 for instructions.)

v 100 MHz front-side bus (FSB)

The FSB is the processor external bus. This bus is the interface between the processors and the system board. The FSB is also known as the processor/host bus.

v Large system memory

The memory bus in the server supports up to 16 GB of system memory. The memory controller provides error correcting code (ECC) support for up to 16 industry-standard, 3.3 V, 168-pin, 8-byte, PCI, PC100 registered, dual inline memory modules (DIMMs). The memory controller also provides Chipkill

™

memory protection. Chipkill memory protection is a technology that protects the system from a single chip failure on a DIMM.

v System-management capabilities

The server comes with an Advanced System Management Processor on the system board. This processor enables you to manage the functions of the server locally and remotely. The Advanced System Management Processor also provides system monitoring, event recording, and dial-out alert capability.

Note: The Advanced System Management Processor is sometimes referred to

as the service processor.

v Integrated network environment support

The server comes with an Ethernet controller on 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

General information 5

provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN).

v Redundant network-interface card (NIC)

The addition of an optional, redundant network-interface card (NIC) provides a failover capability to a redundant 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 NIC. This switching occurs without data loss and without user intervention.

™

v IBM ServerGuide

CDs

The ServerGuide CDs included with xSeries servers provide programs to help you set up the server and install the network operating system (NOS). The ServerGuide program detects the hardware options installed, and provides the correct configuration program and device drivers. In addition, the ServerGuide CDs include a variety of application programs such as IBM Update Connector

™

to help keep the server basic input/output system (BIOS) and microcode updated.

Note: The latest level of BIOS for the server is also available through the World

Wide Web. Refer to “Recovering BIOS” on page 20 for the appropriate World Wide Web addresses and bulletin-board telephone numbers.

The server is designed to be cost-effective, powerful, and flexible. It uses peripheral component interconnect (PCI) bus architecture to provide compatibility with a wide range of existing hardware devices and software applications.

As always, the IBM server meets stringent worldwide certifications for power, electromagnetic compatibility (EMC), and safety. See “Related service information”

on page 127 for additional information.

Reliability, availability, and serviceability

Three of the most important features in server design are reliability, availability, and serviceability (RAS). These factors help to ensure the integrity of the data stored on the server; that the server is available when you want to use it; and that should a failure occur, you can easily diagnose and repair the failure with minimal inconvenience.

The following is an abbreviated list of the RAS features that the server supports.

v Cooling fans with speed-sensing capability (hot-swap) v Error correcting code (ECC) FSBs v ECC L2 cache v ECC memory v Fast power-on self-test (POST) v 45°C (113°F) normal operating temperature for hard disk drives v Parity checking on the small computer system interface (SCSI) bus and PCI

Diagnostics

This section provides basic troubleshooting information to help you resolve some common problems that might occur with the server.

If you cannot locate and correct the problem using the information in this section, refer to “Symptom-to-FRU index” on page 97 for more information.

Diagnostic tools overview

The following tools are available to help you identify and resolve hardware-related problems:

v POST beep codes, error messages, and error logs

The power-on self-test (POST) generates beep codes and messages to indicate successful test completion or the detection of a problem. See “POST” for more information.

v Diagnostic programs and error messages

v Light Path Diagnostics

The server has light-emitting diodes (LEDs) to help you identify problems with server components. These LEDs are part of the light-path diagnostics that are built into the server. By following the path of lights, you can quickly identify the type of system error that occurred. See “Light path diagnostics” on page 16 for more information.

v Error symptoms

These charts list problem symptoms, along with suggested steps to correct the problems. See “Diagnosing errors” on page 23 for more information.

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 installed in the server. This series of tests is called the power-on self-test or POST.

If POST finishes without detecting any problems, a single beep sounds, the first screen of the operating system or application program appears.

If POST detects a problem, more than one beep sounds and an error message appears on the screen. See “POST beep codes” on page 12 and “POST error messages” on page 12 for more information.

Notes:

1. If you have a power-on password or administrator password set, you must type the password and press Enter, when prompted, before POST will continue.

2. A single problem might cause several error messages. When this occurs, work to correct the cause of the first error message. After you correct the cause of the first error message, the other error messages usually will not occur the next time you run the test.

POST beep codes

POST generates beep codes to indicate successful completion or the detection of a problem.

v One beep indicates the successful completion of POST. v More than one beep indicates that POST detected a problem. For more

information, see “Beep symptoms” on page 97

POST error messages

POST error messages occur during startup when POST finds a problem with the hardware or detects a change in the hardware configuration. For a list of POST errors, see “POST error codes” on page 110

Event/error logs

The POST error log contains the three most recent error codes and messages that the system generated during POST. The System Event/Error Log contains all error messages issued during POST and all system status messages from the Advanced System Management Processor.

To view the contents of the error logs, start the Configuration/Setup Utility program (see “Starting the Configuration/Setup Utility program” on page 33); then, select

Event/Error Logs from the main menu.

Small computer system interface messages

If you receive a SCSI error message, see “SCSI error codes” on page 118 Note: If the server does not have a hard disk drive, ignore any message that

indicates that the BIOS is not installed.

You will get these messages only when running the SCSI Select Utility.

ServerGuide error symptoms

Look for symptoms in the left column of the following chart. Probable solutions appear in the right column.

Diagnostic programs and error messages

The server diagnostic programs are stored in upgradable read-only memory (ROM) on the system board. These programs are the primary method of testing the major components of the server.

Diagnostic error messages indicate that a problem exists; they are not intended to be used to identify a failing part. Troubleshooting and servicing of complex problems that are indicated by error messages should be performed by trained service personnel.

Sometimes the first error to occur causes additional errors. In this case, the server displays more than one error message. Always follow the suggested action instructions for the first error message that appears.

The following sections contain the error codes that might appear in the detailed test log and summary log when running the diagnostic programs.

The error code format is as follows:

fff-ttt-iii-date-cc-text message

where: fff is the three-digit function code that indicates the function being

tested when the error occurred. For example, function code 089 is for the microprocessor.

ttt is the three-digit failure code that indicates the exact test failure that

was encountered.

iii is the three-digit device ID. date is the date that the diagnostic test was run and the error recorded. cc is the check digit that is used to verify the validity of the information. text message is the diagnostic message that indicates the reason for the problem.

Diagnostics 13

Text messages

The diagnostic text message format is as follows:

Function Name: Result (test specific string)

where:

Function Name

is the name of the function being tested when the error occurred. This corresponds to the function code (fff) given in the previous list.

Result

can be one of the following:

Passed

This result occurs when the diagnostic test completes without any errors.

Failed This result occurs when the diagnostic test discovers an error. User Aborted

This result occurs when you stop the diagnostic test before it is complete.

Not Applicable

This result occurs when you specify a diagnostic test for a device that is not present.

Aborted

This result occurs when the test could not proceed because of the system configuration.

Warning

This result occurs when a possible problem is reported during the diagnostic test, such as when a device that is to be tested is not installed.

Test Specific String

This is additional information that you can use to analyze the problem.

2. The server supports a maximum of three PCI buses.

3. The server supports a maximum of three power supplies.

Light Path Diagnostics

You can use the light path diagnostics built into the server to quickly identify the type of system error that occurred. The server is designed so that LEDs remain illuminated when the server shuts down, as long as the power supplies are operating properly. This feature helps you to isolate the problem if an error causes the server to shut down.

If the system error LED (on the information LED panel) is not lit and no diagnostics panel LEDs are lit, it means that the light path diagnostics have not detected a system error.

If the system error LED (on the information LED panel) is lit, it means that a system error was detected. Check to see which of the LEDs on the diagnostics panel inside the server are lit and refer to the following table:

Power checkout

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.

A general procedure for troubleshooting power problems is as follows:

1. Power off the system and disconnect the AC cord(s).

2. 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.

3. 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 ″Minimum operating requirements″ on page 122).

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

To use this method it is important to know the minimum configuration required for a system to power up (see page 122). For specific problems, see “Power error messages” on page 119

Recovering BIOS

If the BIOS code in the server has become corrupted, such as from a power failure during a flash update, you can recover the BIOS using the recovery boot block and a BIOS flash diskette.

Note: You can obtain a BIOS flash diskette from one of the following sources:

The flash memory of the server consists of a primary page and a backup page. The J14 jumper controls which page is used to start the server. If the BIOS in the primary page is corrupted, you can use the backup page to start the server; then boot the BIOS Flash Diskette to restore the BIOS to the primary page.

To recover the BIOS:

v Use the ServerGuide program to make a BIOS flash diskette. v Download a BIOS flash diskette from the World Wide Web. Go to

http://www.pc.ibm.com/support/, select IBM Server Support, and make the selections for the server.

1. Turn off the server and peripheral devices and disconnect all external cables and power cords; then, remove the cover.

2. Locate jumper J14 on the processor board (see “System board jumpers” on page 44).

3. Move J14 to pins 1 and 2 to enable secondary boot block page.

20 IBM xSeries 350 Type 8682: Hardware Maintenance Manual

4. Insert the BIOS flash diskette into the diskette drive.

5. Restart the server.

6. The system begins the power-on self-test (POST). Select 1 – Update POST/BIOS from the menu that contains various flash (update) options.

7. When you are asked if you would like to move the current POST/BIOS image to the backup ROM location, type N.

Attention: Typing Y will copy the corrupted BIOS into the secondary page.

8. When you are asked if you would like to save the current code to a diskette, select N.

9. You will be asked to choose which language you wish to use. Select your language (0-7) and press Enter to accept your choice. You will be prompted to remove the diskette and press Enter to restart the system. Remove the flash diskette from the diskette drive.

Attention: Do not press Enter to reboot the system at this time.

10. Power-off the server.

11. Move jumper J14 back to pins 2 and 3 to return to normal startup mode.

12. Restart the server. The system should start up normally.

Troubleshooting the Ethernet controller

This section provides troubleshooting information for problems that might occur with the 10/100 Mbps Ethernet controller.

Network connection problems

If the Ethernet controller cannot connect to the network, check the following: v Make sure that the cable is installed correctly.

Diagnostics 23

The network cable must be securely attached at all connections. If the cable is attached but the problem persists, try a different cable.

If you set the Ethernet controller to operate at 100 Mbps, you must use Category 5 cabling.

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.

v 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.

v Check the Ethernet controller lights on the operator information 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.

– The Ethernet Speed 100 Mbps light illuminates when the Ethernet controller

LAN speed is 100 Mbps.

v Make sure that you are using the correct device drivers, supplied with the server. v Check for operating system-specific causes for the problem. v Make sure that the device drivers on the client and server are using the same

protocol.

v Test the Ethernet controller.

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

Ethernet controller troubleshooting chart

You can use the following troubleshooting chart to find solutions to 10/100 Mbps Ethernet controller problems that have definite symptoms.

Table 2. Ethernet troubleshooting chart

Ethernet controller problem Suggested Action

The server stops running when loading device drivers.

The PCI BIOS interrupt settings are incorrect. Check the following:

v Determine if the interrupt (IRQ) setting assigned to the Ethernet controller is also

assigned to another device in the Configuration/Setup Utility program. Although interrupt sharing is allowed for PCI devices, some devices do not function

well when they share an interrupt with a dissimilar PCI device. Try changing the IRQ assigned to the Ethernet controller or the other device. For example, for NetWare Versions 3 and 4 it is recommended that disk controllers not share interrupts with LAN controllers.

v Make sure that you are using the most recent device driver available from the

World Wide Web.

v Run the network diagnostic program.

The Ethernet controller stopped working when another adapter was added to the server.

The Ethernet controller stopped working without apparent cause.

Check the following:

v Make sure that the hub is turned on. v Check all connections at the Ethernet controller and the hub. v Check the cable. A crossover cable is required unless the hub has an X

designation.

v Use another port on the hub. v If the hub does not support auto-negotiation, manually configure the Ethernet

controller to match the hub.

v If you manually configured the duplex mode, make sure that you also manually

configure the speed.

v Run diagnostics on the LEDs. Check the following:

Note: The Ethernet Transmit/Receive Activity LED illuminates only when data is sent to or by this Ethernet controller.

v Make sure that you have loaded the network device drivers. v The network might be idle. Try sending data from this workstation. v Run diagnostics on the LEDs. v The function of this LED can be changed by device driver load parameters. If

necessary, remove any LED parameter settings when you load the device drivers.

v Make sure that you are using Category 5 cabling when operating the server at 100

Mbps.

v Make sure that the cables do not run close to noise-inducing sources like

fluorescent lights.

Check the following:

v Make sure that the cable is connected to the Ethernet controller. v Make sure that the PCI system BIOS is current. v Reseat the adapter. v Determine if the interrupt (IRQ) setting assigned to the Ethernet adapter is also

assigned to another device in the Configuration/Setup Utility program. Although interrupt sharing is allowed for PCI devices, some devices do not function

well when they share an interrupt with a dissimilar PCI device. Try changing the IRQ assigned to the Ethernet adapter or the other device.

Check the following:

v Run diagnostics for the Ethernet controller. v Try a different connector on the hub. v Reinstall the device drivers. Refer to the operating-system documentation and to

the ServerGuide information.

Configuring the server

In addition to the ServerGuide CDs, you can use the following configuration programs to customize your server hardware:

v Configuration/Setup Utility

The Configuration/Setup Utility program is part of the basic input/output system (BIOS) code that comes with the server. You can use this program to configure serial and parallel port assignments, change interrupt request (IRQ) settings, change the drive startup sequence, set the date and time, and set passwords. See “Using the Configuration/Setup Utility program” for more information.

v SCSISelect Utility

With the built-in SCSISelect Utility program, you can configure the devices attached to the integrated SCSI controller. Use this program to change default values, resolve configuration conflicts, and perform a low-level format on a SCSI hard disk drive. See “Using the SCSISelect utility program” on page 39 for more information.

v ServeRAID programs

The ServeRAID programs come with the optional ServeRAID adapters and with server models that have a ServeRAID adapter preinstalled. If a ServeRAID adapter has been installed in the server, you must use the ServeRAID configuration program to define and configure the disk-array subsystem before you install the operating system.

v ServerGuide CDs

The ServerGuide CDs include software setup and installation tools specifically designed for xSeries servers. You can use these CDs during the initial installation of the server to configure the server hardware and simplify the network operating system installation. The ServerGuide CDs also contain a collection of application programs, which you can install after the server is up and running.

Using the Configuration/Setup Utility program

This section provides the instructions needed to start the Configuration/Setup Utility program and descriptions of the menu choices available.

Starting the Configuration/Setup Utility program

To start the Configuration/Setup Utility program:

Configuring the server 37

Power-on password

After you set a power-on password, you can enable the unattended-start mode. This locks the keyboard and mouse, but allows the server to start the operating system. The keyboard and mouse remain locked until you enter the correct password.

You can use any combination of up to seven characters (A–Z, a–z, and 0–9) for the power-on password. Keep a record of the password in a secure place. If you forget the power-on password, you can regain access to the server by removing the battery and then installing the battery, or by overriding or bypassing the power-on password; see “Setting the password override jumper”

Setting the password override jumper: When a power-on password is set, POST does not complete until you enter the password. If you forget the power-on password, you can regain access to the server through either of the following methods:

v Enter the administrator password at the power-on prompt, if an administrator

password has been set. (See “Administrator password” for details.) Start the Configuration/Setup Utility program and change the power-on password. See “Power-on password”

v Change the position of the jumper on J15 to bypass the power-on password

check. You can then start the Configuration/Setup Utility program and change the power-on password. See “System board component locations” on page 42 for the location of J15.

Notes:

1. Turn off the server, and disconnect all power cords before moving any jumpers.

2. Jumpers J19 and J3 are located on the same jumper block as jumper J15 on the system board. These jumpers are set to Disabled. Do not change the settings on these jumpers.

Attention: If you change the settings on these jumpers, the server will fail.

Table 7. Jumper J15 on the system board

Jumper name Description

J15 Power-on password override Changing the position of this jumper bypasses the power-on

password check if the jumper has been moved since the server was last powered on. You do not need to move the jumper back to the default position after the password is overridden. The default position is a jumper on pins 1 and 2.

Changing the position of this jumper does not affect the administrator password check if an administrator password is set.

For more information on jumper locations, see “Changing jumper positions” on page 69

Administrator password

Select this choice to set an administrator password. The administrator password provides access to all choices on the Configuration/Setup Utility main menu. You can set, change, or delete both the administrator and power-on passwords, and allow a power-on password to be changed by the user.

Installing options 49

Before you begin

Before you begin to install options in the server, read the following information: v Become familiar with the safety and handling guidelines provided in “Safety

information” on page 127 and “Handling electrostatic discharge-sensitive devices”

on page 130 These guidelines will help you work safely while working with the

server or options.

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

supplies, hot-swap drives, hot-swap fans, Active PCI (hot-plug) adapters, or hot-plug USB devices.

v The orange color on components and labels in the server identifies hot-swap or

hot-plug components. This means that you can install or remove the component while the system is running, provided that the system is configured to support this function.

v The blue color on components and labels identifies touch points where you can

grip a component, move a latch, and so on.

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

outlets for the server, monitor, and any other options that you intend to install.

v Back up all important data before you make changes to disk drives. v For a list of supported options for the eServer xSeries 350, refer to

http://www.ibm.com/pc/us/compat on the World Wide Web.

System reliability considerations

To help ensure proper cooling and system reliability, make sure that:

v Each of the drive bays has either a drive or a filler panel installed. v Each of the power supply bays has either a power supply or a filler panel

installed.

v There is at least 50 mm (2 inches) of ventilated space at the sides of the server

and 100 mm (4 inches) at the rear of the server.

v The top cover is in place during normal operation. v The top cover is removed for no longer than 30 minutes while the server is

operating.

v The processor housing cover over the processor and memory area is removed

for no longer than 10 minutes while the server is operating.

v A removed hot-swap drive is replaced within 10 minutes of removal. v Cables for optional adapters are routed according to the instructions provided

with the adapters.

v A failed fan is replaced within 48 hours.

Working inside the server with the power on

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

v Avoid 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 to hang inside the server. v Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist

watches.

50 IBM xSeries 350 Type 8682: Hardware Maintenance Manual

v Remove items from your shirt pocket (such as pens or pencils) that could fall into

the server as you lean over it.

v Avoid dropping any metallic objects, such as paper clips, hair pins, or screws,

into the server.

Handling static-sensitive devices

Static electricity, though harmless to you, can seriously damage server components or options.

Note: When you are adding an internal option, do not open the static-protective

package containing the option until you are instructed to do so.

When you handle options and other server components, take these precautions to avoid damage from static electricity:

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

you.

v Always handle components carefully. Handle adapters, the memory board, and

memory modules (DIMMs) by the edges. Never touch any exposed circuitry.

v Prevent others from touching components. v When you are installing a new option, touch the static-protective package

containing the option to a metal expansion-slot screw or other unpainted metal surface on the server for at least two seconds. (This reduces static electricity from the package and from your body.)

v When possible, remove the option and install it directly into the server without

setting the option down. When this is not possible, place the static-protective package that the option comes in on a smooth, level surface and place the option on it.

v Do not place the option on the server’s covers or any metal surface.

Installing internal drives

If you add different types of drives, the system can read multiple types of media and store more data. Several types of drives are available, such as:

v Diskette v Hard disk v CD-ROM v DVD-ROM v Tape

Note: The server supports external tape drives; however, the server does not

support internal tape drives.

The server contains hardware that enables you to replace a failed hard disk drive without turning off the server. Therefore, you have the advantage of continuing to operate the system while a hard disk drive is removed or installed. These drives are known as hot-swap drives.

Each hot-swap drive bay has two indicator lights on the front of the server (see “Start the server” on page 8). If the amber hard-disk status light for a drive is lit continuously, that individual drive is faulty and requires replacement. When the hard-disk status light indicates a drive fault, you can replace a 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.

Internal drive bays

Internal drives are installed in bays. The server supports up to a maximum of six 1-inch (26 mm) slim high, 3.5 inch, hot-swap hard disk drives when the media bay option is installed.

v The server comes with one integrated drive electronics (IDE) CD-ROM drive and

one 3.5-inch, 1.44 MB diskette drive.

v The CD-ROM drive bay (bottom left front) supports 5.25-inch, half-high,

removable-media drives. However, you cannot install additional removable-media drives in the server.

Bays 1 through 3 are located in the standard hard disk drive cage, to the left of bays 4 through 6 in the optional hard disk drive cage.

Note: The server does not support half-high hot-swap drives or internal tape

drives.

v The hot-swap bays connect to a hot-swap drive backplane. The backplane is a

printed circuit board behind the bays.

bays.

To install a drive in a hot-swap bay:

1. Review “Before you begin” on page 50

2. Unlock and open the server front door.

Drive tray assembly

Filler panel

Drive tray handle (in open position)

Attention: To maintain proper system cooling, do not operate the server for

more than 10 minutes without either a drive or a filler panel installed for each bay.

3. Remove the filler panel from one of the empty hot-swap bays by inserting your

finger into the depression at the left side of the filler panel and pulling it away from the server.

4. Install the hard disk drive in the hot-swap bay:

a. Ensure that the tray handle is open (that is, perpendicular to the drive). b. Align the drive assembly so that it engages the guide rails in the bay. c. Gently push the drive assembly into the bay until the drive stops. d. Push the tray handle to the closed (locked) position. e. Check the hard disk drive status indicator to verify that the hard disk drive is

operating properly. If the amber hard-disk status light for a drive is lit continuously, that

individual drive is faulty and needs to be replaced. If the green hard-disk activity light is flashing, the drive is being accessed.

Note: If the server has a ServeRAID controller or adapter installed, you might

need to reconfigure the disk arrays after installing hard disk drives. Refer to Using IBM ServeRAID on the Documentation CD or the Hardware Maintenance Manual pertaining to the specific RAID adapter for information.

62 IBM xSeries 350 Type 8682: Hardware Maintenance Manual

Installing memory-module kits

The illustrations in this document might differ slightly from your hardware. Adding memory to the server is an easy way to make programs run faster. You can

increase the amount of memory in the server by installing memory-module options. You must install a bank of four matched dual-inline memory modules (DIMMs).

Notes:

1. The DIMM options available for the server are 128 MB, 256 MB, 512 MB, and 1 GB. The server supports a minimum of 512 MB (4 x 128MB) and a maximum of 16 GB (16 x 1GB) of system memory.

2. When 4 GB of memory is installed in the server, the amount of usable memory will be reduced depending on the system configuration. A certain amount of memory must be reserved below 4 GB for system resources. A second reduction in the usable memory is made when 16 GB of memory is installed.

3. The server comes with a minimum of 512 MB (4x128) memory installed in bank

1. When you install additional DIMMs, be sure to follow the DIMM population sequence in Table 11..

4. All the DIMMs installed in a bank must be the same size, speed, type, and technology. You can mix compatible DIMMs from various manufacturers.

5. All the banks do not have to contain DIMMs of the same size, speed, type, and technology. You can mix compatible DIMMs from various manufacturers.

6. The memory board contains 16 DIMM connectors and utilizes 4-way memory interleaving. See Table 11

The 4-way memory interleave technology in the server requires that you install DIMMs in all four connectors in each populated bank.

7. Install only 3.3 V, 168-pin, 8-byte, 100 MHz, PCI, PC100-322-622R, registered synchronous dynamic random-access memory (SDRAM) with error correcting code (ECC), DIMMs. Only 100 MHz, 72-bit, registered, synchronous, x4 SDRAM configuration DIMM memory is supported for the 128 MB, 256 MB, 512 MB, and 1 GB DIMMs.

8. Installing or removing DIMMs changes the configuration information in the server. Therefore, after installing or removing a bank of 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 “Configuring the server” on page 33 for more information.

Install the DIMMs in the order provided in Table 11

Installing a microprocessor kit

The server comes with one microprocessor installed on the system board. The server supports up to four microprocessors. If you install at least one additional 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:

v Review the information in “Before you begin” on page 50 v Thoroughly review the documentation that comes with the microprocessor, so

that you can determine whether you need to update the server basic input/output system (BIOS). The latest level of BIOS for the server is available through the World Wide Web and the IBM Bulletin Board System (BBS). Go to http://www.pc.ibm.com/support/, select IBM Servers, and make the selections for the server.

v Obtain an SMP-capable operating system (optional). For a list of supported

operating systems, see http://www.ibm.com/pc/us/compat/ on the World Wide Web.

Attention: To avoid damage and ensure proper server operation when you install a new or an additional microprocessor, use microprocessors that have the same cache size and type, and the same clock speed. Microprocessor internal and external clock frequencies must be identical.

Notes:

1. To order additional microprocessor options, contact your IBM reseller or IBM marketing representative.

2. The server comes standard with one microprocessor installed in microprocessor connector J34 (slot 1) on the system board, and a terminator card in microprocessor slot 4. The microprocessor in slot 1 is the startup (boot) microprocessor. The microprocessor installed in microprocessor connector J35 is microprocessor 2 (slot 2); the microprocessor installed in microprocessor connector J36 is microprocessor 3 (slot 3); and the microprocessor installed in microprocessor connector J37 is microprocessor 4 (slot 4). If more than one microprocessor is installed, the highest numbered microprocessor is the microprocessor from which the server will start. The lower numbered microprocessors are used as application microprocessors.

3. If you replace the microprocessors in the server with microprocessors of a different speed, be sure to set the microprocessor-core-frequency-selection jumper block correctly, as described in this section. For a list of supported microprocessor speeds, see http://www.ibm.com on the World Wide Web.

4. The server does not support replaceable voltage regulator modules (VRMs).

If you need to install additional microprocessors, install them in the following order:

v Slot 1 (first slot, connector J34) v Slot 2 (second slot, connector J35) v Slot 3 (third slot, connector J36) v Slot 4 (fourth slot, connector J37)

Attention: The server comes with a terminator card installed in microprocessor slot 4. To ensure proper server operation, the terminator card must remain installed in microprocessor slot 4 until you have installed microprocessors in slots 1 through 3.

The server comes with two SCSI cables. One cable connects the internal SCSI channel connector to the standard hot-swap-drive backplane. The other cable is not connected to the server when the server is shipped and must be installed in the server. If you want to use the external LVD SCSI channel connector to connect external SCSI devices to the server, remove the knockout on the rear of the server and install the LVD SCSI cable that comes with the server.

Installing options 79

Note: If you install a PCI RAID adapter to configure and manage the internal

hot-swap drives, you must move the SCSI cable from the system-board SCSI connector to an internal channel connector on the RAID adapter. See “Cabling example for the ServeRAID adapter” on page 56 for additional information.

SCSI cabling requirements

If you plan to attach external SCSI devices, you must order additional SCSI cables. To select and order the correct cables for use with external devices, contact your IBM reseller or IBM marketing representative.

For information about the maximum length of SCSI cable between the terminated ends of the cable, refer to the ANSI SCSI standards. Adhering to these standards will help ensure that the server operates properly.

Setting SCSI IDs

Each SCSI device connected to a SCSI controller must have a unique SCSI ID. This ID enables the SCSI controller to identify the device and ensure that different devices on the same SCSI channel do not attempt to transfer data simultaneously. SCSI devices that are connected to different SCSI channels can have duplicate SCSI IDs. The following table lists the SCSI IDs for devices that are connected to one channel. Note that the hot-swap hard disk drive bay numbers are from bottom to top.

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).

To access the Ethernet port, connect a Category 3, 4 or 5 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) connector has two lights. The Ethernet link-status light is on the left. When this green light is on, there is an active connection on the Ethernet port. The Ethernet transmit/receive activity light on the right. When this amber light is on, there is activity between the server and the network. These lights have the same functions as the Ethernet link-status light and the Ethernet transmit/receive activity light on the information panel (see “Information LED panel” on page 9).

Configuring the Ethernet controller

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. 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.

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

Failover for redundant Ethernet

The IBM 10/100 Fault Tolerant Adapter is an optional redundant network interface card (NIC adapter) that you can install in the server. If you install this NIC adapter and connect it to the same logical LAN segment as the primary Ethernet controller, you can configure the server to support a failover function. You can configure either the integrated Ethernet controller or the NIC adapter as the primary Ethernet controller. In failover mode, if the primary Ethernet controller detects a link failure,

Installing options 83

all Ethernet traffic associated with it is switched to the redundant (secondary) controller. If the appropriate device drivers are installed, this switching occurs without any user intervention. When the primary link is restored to an operational state, the Ethernet traffic switches back to the primary Ethernet controller. The switch back to the primary Ethernet controller can be automatic or manually controlled, depending on the setup and operating system.

Note that only one controller in the redundant pair is active at any given time. For example, if the primary Ethernet controller is active, then the secondary Ethernet controller cannot be used for any other network operation.

Note: Your operating system determines the maximum number of IBM 10/100 Fault

Tolerant Adapters that you can install in the server. See the documentation that comes with the adapter for more information.

Considerations when combining failover and hot-plug functions: If your operating system supports hot-plug PCI adapters and the optional redundant NIC adapter is installed in a hot-plug PCI slot, you can replace the NIC adapter without powering off the server — even if it is the primary Ethernet controller. Disconnecting the Ethernet cable from the primary Ethernet controller will cause the Ethernet traffic to switch automatically to the secondary Ethernet controller. This can be very useful if a faulty adapter causes a network problem, or if you want to upgrade the primary adapter hardware.

Note: If you hot-replace the primary adapter while the Ethernet traffic is being

handled by the secondary Ethernet controller, the traffic does not automatically switch back to the primary adapter when the primary adapter comes back online. See “Configuring for failover”..

Configuring for failover: The failover feature currently is supported by Windows NT Server and IntraNetWare. The setup required for each operating system follows.

Windows NT Server:

IBM offers hot-plug support for Windows NT Server Version 4.0. Failover can work in conjunction with hot-plug support or independently. If you are not using hot-plug support, go to “Windows NT Server failover setup” on page 85

To install the IBM 10/100 Fault Tolerant Adapter device drivers:

1. Add the redundant NIC adapter according to the instructions that are provided with the adapter.

2. Use the ServerGuide CDs to install the AMD PCNet Ethernet Family adapter device driver.

3. Do not select the Grouping box at this point; you must first restart the machine.

4. From the Windows NT Server desktop, select Control Panel, then select the Network icon, then select the Adapters tab.

5. Highlight one of the adapters that will be in the redundant pair and then click the Properties... button.

6. Check the Grouping box. This will show the possible combinations for redundant pairs.

7. Select the adapter pair you want and then select OK. Note that the integrated Ethernet controller is located at PCI C.

Two options are available for recovering from a failover condition. The options are determined by the Enable for DMI / Hot Swap Support checkbox. If the IBM Hot Plug PCI for Windows NT Server 4.0 package is installed, this checkbox will appear at the bottom of the Adapter Properties panel. If you do not have the IBM Hot Plug PCI for Windows NT Server 4.0 package installed on the server, you will not see the Enable for DMI / Hot Swap Support checkbox.

Installing options 85

If the Enable for DMI / Hot Swap Support checkbox is not checked or is not present, traffic will automatically switch back to the primary adapter when the primary link status is restored. In this mode, the adapter cannot be hot-swapped. Users with the IBM Hot Plug PCI for Windows NT Server 4.0 package installed should check the Enable for DMI / Hot Swap Support checkbox.

If the Enable for DMI / Hot Swap Support checkbox is checked, traffic will remain on the secondary adapter until the user directs it to return to the primary adapter. This can be done after the hot-swap replacement of the primary adapter or by using the DMI interface.

8. Select Close to exit from the Network setup. When you restart the server, the failover function will be in effect.

If a failover occurs, a message is written to the NT Event Viewer log. In addition, if the Enable for DMI / Hot Swap Support checkbox is checked, a DMI alert will also be generated.

IntraNetWare:

The IBM PCI Hot Plug System Bus Driver Diskette for Novell Netware V4.41, V4.42, and V5.0 is available for download from the IBM Web site at:

http://www.pc.ibm.com/support

The failover function is now enabled. If a failover occurs:

v The operating system console generates a message. v The custom counters for the device driver contain variables that define the state

of the failover function and the location of the redundant pair. You can use the NetWare Monitor to view the custom counters.

Note: If the primary adapter was hot-replaced while the Ethernet traffic was being

handled by the secondary Ethernet controller, the traffic does not automatically switch back to the primary adapter when the primary adapter comes back online. In this case, issue the command:

LOAD d:\path\PCNTNW SCAN

where d and path are the drive and path where the driver is located. This command causes the device driver to locate the primary adapter and switch the Ethernet traffic to it.

Advanced System Management ports

The server has three communication ports dedicated to the Advanced System Management processor. One port uses a standard D-shell serial-port connector, connector C. The other two ports, which are used for the ASM Interconnect function, use a dual RJ-45 connector.

You can attach a dedicated modem to the D-shell system-management connector on the rear of the server to communicate with the integrated Advanced System Management processor.

The ASM Interconnect function uses the RJ-45 system-management connectors. This function enables you to connect the Advanced System Management processors of several rack-mounted servers so that they can communicate with each other in half-duplex mode.

The following illustration shows the connectors and lights for the Advanced System Management Interconnect board.
