Hot-swap hard disk drive activity LED (some models)

On SCSI hot-swap server models, each hot-swap drive has a hard disk
drive activity LED. When this green LED is flashing, it indicates that the
drive is in use.

Hot-swap hard disk drive status LED (some models)

On SCSI hot-swap server models, each hot-swap hard disk drive has an
amber status LED. If the status LED for a drive is lit continuously, it
indicates that the individual drive is faulty. The interpretation of a flashing
status LED depends on the SCSI controller that is connected to the
hot-swap drive, as follows:

When the drive is connected to an optional ServeRAID™ adapter, a slowly
flashing (one flash per second) status LED indicates that the drive is being
rebuilt. When the LED is flashing rapidly (three flashes per second), it
indicates that the controller on the adapter is identifying the drive.

Ethernet transmit/receive activity LED

are available at http://www.ibm.com/pc/support.

The following configuration programs and capabilities come with the server:

v Configuration/Setup Utility program

The Configuration/Setup Utility program is part of the basic input/output system
(BIOS) code in the server. Use it to configure serial port assignments, change
interrupt request (IRQ) settings, change the startup-device sequence, set the
date and time, and set passwords.

v IBM ServerGuide Setup and Installation CD

The ServerGuide program provides software-setup tools and installation tools
that are designed for the server.

v Boot Menu program

The Boot Menu program is part of the BIOS code in the server. Use it to
temporarily assign a device to be first in the startup sequence, overriding the
startup sequence that is set in the Configuration/Setup Utility program.

v Ethernet controller configuration

The Ethernet controller is integrated on the system board. You do not need to set
any jumpers or configure the controller. However, you must install a device driver.
For device drivers and information about configuring the Ethernet controller, see
the Broadcom NetXtreme Gigabit Ethernet Software CD that comes with the
server. For updated information about configuring the controller, go to
http://www.ibm.com/pc/support/.

Chapter 3. Diagnostics

This chapter provides basic troubleshooting information to help solve some common
problems that might occur with the server.

If you cannot locate and correct the problem using the information in this section,
see Appendix A, “Getting help and technical assistance,” on page 141 for more
information.

General checkout

Follow the checkout procedure for diagnosing hardware problems. Review the
following information before performing the checkout procedure:

v Read Appendix B, “Safety information,” on page 143.
v The server diagnostic programs are stored on the IBM Enhanced Diagnostics

CD. These programs provide the primary methods of testing the major
components of the server. If you are not sure 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 correctly.

v When you run the diagnostic programs, a single problem might cause several

error messages. If you receive several error messages, correct the cause of the
first error message. The other error messages might not occur the next time you
run the diagnostic programs.

v Before running the diagnostic programs, you must determine whether the failing

server is part of a shared hard disk drive cluster (two or more servers sharing
external storage devices). If you suspect that it is part of a cluster, you can run
all diagnostic programs except the ones that test the storage unit (that is, a hard
disk drive in the storage unit) or the storage adapter that is attached to the
storage unit. The failing server might be part of a cluster if any of the following
conditions is true:

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

least one of the attached storage units is also attached to another server or
unidentifiable device.

– One or more servers are located near the failing server.

Important:

v

1. For servers that are part of a shared hard disk drive cluster, run one test at a
time. Do not run any suite of tests, such as “quick” or “normal” tests, because
this could enable the hard disk drive diagnostic tests.

2. If more than one error code is displayed, correct the first error. The other
error codes might not occur the next time you run the diagnostic programs.

3. If the server is suspended and a POST error code is displayed, see “POST
error codes” on page 99.

4. If the server is suspended and no error message is displayed, see “Error
symptoms” on page 109 and “Undetermined problems” on page 127.

5. For information about power-supply problems, see “Power checkout” on page

21.

6. For intermittent problems, check the error log; see “Diagnostic programs,
error codes, and messages” on page 14.

12 xSeries 226 Type 8488 and 8648: Hardware Maintenance Manual and Troubleshooting Guide

Diagnostic tools overview

The following tools are available to help you diagnose and solve hardware-related
problems:

v POST error logs

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

The POST error log contains the three most recent error codes and messages
that the server has generated during POST.

The system-error log contains all the error messages that were issued during
POST.

Note: The system-error log is available only with the Remote Supervisor Adapter

II.

See “POST error logs” for more information.

v Diagnostic programs and error messages

The server diagnostic programs are the primary method of testing the major
components of the server (see “Diagnostic programs, error codes, and
messages” on page 14).

v System board error LEDs

These LEDs can help to pinpoint the source of a hardware problem (see “System
board error LEDs” on page 17).

v Ethernet controller troubleshooting

This section provides information about Ethernet problems (see “Troubleshooting
the Ethernet controller” on page 21).

POST error logs

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, and the first
screen of the operating system or application program appears.

If POST detects a problem, more than one beep sounds, an error message appears
on the screen, or both (see “Beep symptoms” on page 97 and “POST error codes”
on page 99).

Note: 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.

The POST error log contains the three most recent error codes and messages that
the system generated during POST.

The system-error log contains all messages that were issued during POST and all
system status messages from the service processor.

Note: The system-error log is available only with the Remote Supervisor Adapter II.

Chapter 3. Diagnostics 13

You can view the contents of the system-error log from the Configuration/Setup
Utility program or from the diagnostic programs.

Viewing error logs from the Configuration/Setup Utility program

Start the Configuration/Setup Utility program; then, select Error Logs from the main
menu (see “Starting the Configuration/Setup Utility program” on page 10).

15.

2. Select Hardware Info from the top of the diagnostic programs screen.

3. Select System Error Log from the list that appears; then, follow the instructions

on the screen.

Note: The system-error log is available only with the Remote Supervisor

Adapter II.

Diagnostic programs, error codes, and messages

The server diagnostic programs are stored on the IBM Enhanced Diagnostics CD.
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.

Error codes that might be displayed are listed at “Diagnostic error codes” on page

104.

Notes:

1. Depending on the server configuration, some of the error codes might not
appear when you run the diagnostic programs.

2. If diagnostic error codes appear that are not listed in the tables, make sure that
the server has the latest levels of BIOS, Remote Supervisor Adapter II, and
ServeRAID code installed.

Information about updating the firmware of the Remote Supervisor Adapter II can be
found in the Remote Supervisor Adapter II User’s Guide.

20 xSeries 226 Type 8488 and 8648: Hardware Maintenance Manual and Troubleshooting Guide

Power checkout

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

Follow this general procedure for troubleshooting power problems:

1. Turn off the server and disconnect all ac power cords.

2. Check for loose cables in the power subsystem. Also check for short circuits.
For example, a loose screw can cause a short circuit on a circuit board.

3. Remove adapters and disconnect the cables and power connectors to all
internal and external devices until the server is at the minimum configuration
that is required to start the server (see “Minimum operating requirements” on
page 117).

4. Reconnect all ac power cords and turn on the server. If the server starts up
successfully, replace adapters and devices one at a time until the problem is
isolated. If the server does not start up from the minimal configuration, replace
FRUs of minimal configuration one at a time until the problem is isolated.

To use this method, you must know the minimum configuration that is required for
the server to start (see page 127).

Troubleshooting the Ethernet controller

This section provides troubleshooting information for problems that might occur with
the 10/100/1000 Mbps Ethernet controller.

Network connection problems

If the Ethernet controller cannot connect to the network, check the following
conditions:

v Make sure that the cable is installed correctly.

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

If you set the Ethernet controller to operate at either 100 Mbps or 1000 Mbps,
you must use Category 5 or higher cabling.

v Determine whether the hub supports auto-negotiation. If it does not, try

configuring the integrated Ethernet controller manually to match the speed and
duplex mode of the hub.

v Check the Ethernet controller LEDs on the rear of the server.

These LEDs indicate whether there is a problem with the connector, cable, or
hub:
– The Ethernet transmit/receive activity LED, on the rear of the server, is lit

when the Ethernet controller sends or receives data over the Ethernet
Network. If the Ethernet transmit/receive activity LED is off, make sure that
the hub and network are operating and that the correct device drivers are
installed.

– The Ethernet link status LED, on the rear of the server, is lit when the

Ethernet controller receives a LINK pulse from the hub. If the LED is off, there
might be a defective connector or cable or a problem with the hub.

v Make sure that you are using the correct device drivers, which are 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.

Chapter 3. Diagnostics 21

v Test the Ethernet controller.

The way the Ethernet controller is tested depends on which operating system
you are using (see the Ethernet controller device driver readme files).

Chapter 4. Customer replacement units

This chapter provides basic instructions for installing hardware options in the server.
These instructions are intended for users who are experienced with setting up IBM
server hardware.

Installation guidelines

Before you begin installing options, read the following information:

v Read Appendix B, “Safety information,” on page 143, and the guidelines in

“Handling static-sensitive devices” on page 26. This information will help you
work safely with the server and options.

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

hot-plug Universal Serial Bus (USB) devices.

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 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 need to access the inside of the server to install options, you might

find it easier to lay the server on its side.

v For a list of supported options for the server, go to http://www.ibm.com/pc/

compat/.

System reliability guidelines

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

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

compatibility (EMC) shield installed.

v There is adequate space around the server to allow the server cooling system to

work properly. Leave approximately 50 mm (2 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.
v You have replaced a failed fan as soon as possible.
v You have replaced a hot-swap drive within 2 minutes of its removal.
v You do not remove the air baffle when the server has power or is running.

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

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

microprocessor and heat sink.

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 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 part of the server for at least 2 seconds. This drains static electricity from
the package and from your body.

v Remove the device from its package and install it directly into the server without

setting down the device. If it is necessary to set down the device, put it back into
its static-protective package. Do not place the device on the server cover or on a
metal surface.

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

indoor humidity and increases static electricity.

Chapter 4. Customer replacement units 33

Installing a memory module

The following notes describe the types of dual inline memory modules (DIMMs) that
the server supports and other information that you must consider when installing
DIMMs:

v The server comes with either two 256 MB or two 512 MB memory DIMMs

installed in DIMM 1 and DIMM 2 memory connectors. The second pair of DIMMs
must be installed in DIMM 3 and DIMM 4 memory connectors and the third pair
in DIMM 5 and DIMM 6 memory connectors.

v DIMMs must be installed in matched pairs. The DIMMs in each pair must be the

same size, speed, type, and technology as each other but do not have to match
the other pairs. You can mix compatible DIMMs from various manufacturers.

v Install only 1.8 V, 184-pin, double-data-rate 2 (DDR2), PC2-3200, registered,

synchronous dynamic random-access memory (SDRAM) with error correcting
code (ECC), dual inline memory modules (DIMMs). These DIMMs must be
compatible with the latest PC2-3200 SDRAM buffered DIMM specification. For a
list of supported options for the server, go to http://www.ibm.com/pc/; then, select
your country and navigate to the list of options for the server.

v The system board contains six DIMM connectors and supports two-way memory

interleaving when the DIMMs are installed in pairs and functioning properly. If
one DIMM in the pair fails, the server runs in single-channel mode
(non-interleaving). A failed DIMM must be replaced as soon as possible;
otherwise, the server will not start (boot).

v The DIMM-installation sequence is based on single-rank DIMMs, double-rank

DIMMs, and mixing single-rank and double-rank DIMMs. Single-rank DIMMs are
256 MB, 512 MB, and 1 GB memory modules. Double-rank DIMMs are 2 GB
memory modules. The following table lists the DIMM-installation sequence for the
server maximum memory capacity using mixed single-rank and double-rank
DIMMs.

Notes:

1. Do not install four 2 GB double-rank DIMMs for the server maximum capacity
(8 GB) configuration; the server does not support it.

2. You can install pairs of 256 MB, 512 MB, 1 GB, and 2 GB DIMMs in the
server, but for the server maximum capacity you must use the
DIMM-sequence in the table below.

3. You can install any combination of DIMM pairs in the server; however, you
can install only two 2 GB double-rank DIMMs in the server, and they must go
in DIMM connectors 1 and 2. Do not install 2 GB double-rank DIMMs in any
connectors other than DIMM connectors 1 and 2.

4. If you order DIMMs from IBM, the variable 2R in the description for the
memory indicates that the DIMM is a double-rank 2 GB DIMM.

Table 2. Maximum memory capacity (8 GB) and installation sequence mixing single-rank
and double-rank DIMMs

v The DIMM options that are available for the server are 256 MB, 512 MB, 1 GB,

and 2 GB memory modules. The server supports a minimum of 256 MB and a
maximum of 8 MB (when using 2 GB double-rank DIMMs) of system memory.

Important: Although the server supports a maximum of 8 GB of system

memory, some Microsoft® Windows® operating systems recognize
and support only a lesser amount of system memory, as shown in
the following table.

Windows operating system Maximum memory supported

Windows Server 2003, Web Edition 2 GB
Windows Server 2003, Standard Edition 4 GB

v The memory controller in the server provides Chipkill™ memory protection if the

DIMMs are 1 GB or larger, or if the server is populated with 512 MB x4 DIMMs.
Chipkill memory protection is a technology that protects the server from a single
chip failure on a DIMM.

v The amount of usable memory is reduced depending on the system

configuration. A certain amount of memory must be reserved for system
resources. The BIOS displays the total amount of installed memory and the
amount of configured memory.

Complete the following steps to install a DIMM:

1. Read Appendix B, “Safety information,” on page 143, and the “Installation
guidelines” on page 25.

2. Turn off the server and peripheral devices, and disconnect the power cords and
all external cables.

3. Remove the side cover (see “Removing the side cover” on page 28).

4. Remove the support bracket (see “Removing and installing the support bracket”
on page 32).

5. Open the microprocessor air baffle (see “Opening and closing the
microprocessor air baffle” on page 33).

6. Locate the DIMM connectors on the system board (see “System board option
connectors” on page 85). Determine the connectors into which you will install
the DIMMs.

Chapter 4. Customer replacement units 35

7. Install the DIMMs in the sequence shown in the notes at the beginning of this
section.

Attention: To avoid breaking the retaining clips or damaging the DIMM

connectors, open and close the clips gently.

a. Open the retaining clips and, if necessary, remove any existing DIMM.
b. Touch the static-protective package containing the DIMM to any unpainted

metal surface on the server. Then, remove the new DIMM from the package.
c. Turn the DIMM so that the DIMM keys align correctly with the slot.
d. Insert the DIMM into the connector, pressing gently but firmly until the

retaining clips close.

Insert the DIMM into the connector by aligning the edges of the DIMM with the

8.
slots at the ends of the DIMM connector. Firmly press the DIMM straight down
into the connector by applying pressure on both ends of the DIMM
simultaneously. The retaining clips snap into the locked position when the DIMM
is firmly seated in the connector. If there is a gap between the DIMM and the
retaining clips, the DIMM has not been correctly installed. Open the retaining
clips, remove the DIMM, and then reinsert it.

9. If you have other options to install or remove, do so now; otherwise, close the
microprocessor air baffle (see “Opening and closing the microprocessor air
baffle” on page 33), replace the support bracket (see “Removing and installing
the support bracket” on page 32), and go to “Completing the installation” on
page 60.

information that you must consider when installing a hard disk drive:

v Make sure that you have all the cables and other equipment that is specified in

the documentation that comes with the drive.

v Check the instructions that come with the drive to see whether you must set any

switches or jumpers on the drive. If you are installing a SCSI device, be sure to
set the SCSI ID for that device.

v Diskette drives, tape drives, CD-ROM, CD-RW, and DVD drives are examples of

removable-media drives. You can install removable-media drives in bays 1, 2,
and 3 only.

v The integrated IDE controller in the server supports up to two IDE devices.
v You can install a 3.5-in. slim-high or 5.25-in. half-high removable-media drive,

such as a tape backup drive, CD-RW drive, or DVD drive, in bay 2.

v The server supports only one diskette drive.
v To install a 3.5-in. drive in a 5.25-in. bay, you must use the 5.25-in. conversion

kit. Contact IBM to order the conversion kit.

v The electromagnetic interference (EMI) integrity and cooling of the server are

protected by having all bays and PCI slots covered or occupied. When you install
a drive or PCI adapter, save the EMC shield and filler panel from the bay or the
PCI adapter slot cover in the event you later remove the option.

v For a complete list of supported options for the server, go to

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

Installing a drive in bay 2

Complete the following steps to install a drive in bay 2:

1. Read Appendix B, “Safety information,” on page 143, and the “Installation
guidelines” on page 25.

2. Turn off the server and peripheral devices, and disconnect the power cords
and all external cables.

3. Remove the side cover (see “Removing the side cover” on page 28).

4. Remove the support bracket (see “Removing and installing the support

8. Set any jumpers or switches on the drive according to the documentation that
comes with the drive.

Note: You might find it easier to install the new drive from the front and then

attach the cables.

9. If you are installing a 3.5-in. drive in bay 2, attach the 5.25-in. conversion kit,
which you can order from IBM, to the 3.5-in. drive.

10. Remove the large drive clip from the side of the drive cage for bays 1 through

3. Slide the drive clip toward the rear of the server; then, snap the drive clip
into the screw holes on the side of the drive or conversion kit.

11. Slide the drive into the drive bay until it snaps in place.

12. Determine whether the drive is an IDE or SCSI device; then, connect one end
of the applicable signal cable into the back of the drive and make sure that the
other end of this cable is connected into the applicable IDE or SCSI connector
on the system board.

v If you are installing a SCSI removable-media drive, use the one-drop SCSI

cable that comes with the drive and connect it to SCSI channel A (SCSI1).
See “Power and signal cables for internal drives” on page 44 for additional
information about cabling drives and “System board internal connectors” on
page 86 for the location of IDE and SCSI connectors on the system board.

v If there are open connectors on the cable connecting an existing IDE drive,

you can use this cable to connect the new drive. The 4-connector SCSI
cable that comes with non-hot-swap model servers cannot be used to
connect a SCSI drive in bay 2.

Route the signal cable so that it does not block the airflow to the rear of the

13.
drives or over the microprocessor and memory.

14. If you have another drive to install or remove, do so now.

15. If you have other options to install or remove, do so now; otherwise, replace
the support bracket (see “Removing and installing the support bracket” on

Installing a hot-swap SCSI hard disk drive in bay 4, 5, 6, 7, 8, or 9

Some server models support hot-swap hard disk drives. The SCSI ID for each
hot-swap hard disk drive is printed on the hot-swap lock bar.

Before you install a hot-swap hard disk drive, read the following information:

v Inspect the drive tray for signs of damage.
v Make sure that the drive is correctly installed in the tray.
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.

v All hot-swap drives in the server must have the same speed rating; if you mix

speed ratings, all drives will operate at the speed of the slowest drive.

v You do not have to turn off the server to install hot-swap drives in the hot-swap

drive bays.

v Set the drive jumpers either to disable auto-start or to delay startup, to prevent

overtaxing the system power supply by all drives trying to spin up at once.

v Install hot-swap hard disk drives in this sequence: bay 9, bay 8, bay 7, bay 6,

bay 5, and bay 4.

v If the server has an optional RAID adapter, see the documentation that comes

with the adapter for instructions for installing a hard disk drive.

40 xSeries 226 Type 8488 and 8648: Hardware Maintenance Manual and Troubleshooting Guide

v Each hot-swap drive has two LEDs: the hard disk drive activity LED and the hard

disk drive status LED. When the green hard disk drive activity LED is flashing, it
indicates that the controller is accessing the hard disk drive. When the amber
hard disk drive status LED is lit continuously, it indicates that the drive is faulty
and must be replaced. When the amber hard disk drive status LED is flashing, it
indicates that the drive is being rebuilt.

server hot-swap bays are connected to a SCSI backplane. This backplane is

5. Install the hard disk drive in the hot-swap bay:
a. Make sure that the tray handle is open (that is, perpendicular to the drive).
b. Align the drive assembly with 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 make sure that the hard disk

drive is operating properly. (You might have to restart the server before the
drive is recognized.) If the amber hard disk drive status LED for a drive is lit
continuously, it indicates that the drive is faulty and must be replaced. If the
green hard disk drive activity LED is flashing, it indicates that the drive is
being accessed.

Note: If the server is configured for RAID operation using an optional

ServeRAID adapter, you might have to reconfigure the disk arrays
after installing hard disk drives. See the ServeRAID documentation
on the IBM ServeRAID Support CD for additional information about
RAID operation and complete instructions for using ServeRAID
Manager.

If you are installing additional hot-swap hard disk drives, do so now; otherwise,

Installing a simple-swap Serial ATA hard disk drive in bay 4, 5, 6, or 7

Some server models support simple-swap Serial ATA (SATA) hard disk drives,
which are easily accessible from the front of the server. Drives are installed starting
at the bottom, in bay 7. Additional drives are then installed in bays 6, 5, and 4.

Before you install a simple-swap SATA hard disk drive, read the following
information:

v Read the documentation that comes with the drive for cabling instructions.
v You can install two simple-swap SATA hard disk drives in the server.

Note: You can install a third and fourth SATA drive if you install an optional

ServeRAID-7t S-ATA adapter in the server. The optional ServeRAID-7t
S-ATA adapter comes with two cables that you can use to cable the third
and fourth SATA drives. If you install the optional ServeRAID-7t S-ATA
adapter, all four SATA drives must then be connected to the ServeRAID-7t
S-ATA adapter instead of the system board. See “Installing an adapter” on
page 51 and “Cabling an optional SATA adapter” on page 55, or see the
the optional ServeRAID-7t S-ATA adapter documentation.

v Install simple-swap S ATA hard disk drives in this sequence: bay 7, bay 6, bay 5,

and bay 4.

v Bays 4, 5, 6, and 7 are simple-swap bays and do not require cabling.

Complete

the following steps to install a simple-swap hard disk drive:

1. Read Appendix B, “Safety information,” on page 143, and the “Installation
guidelines” on page 25.

2. Turn off the server and peripheral devices and disconnect all external cables
and power cords.

3. Unlock the side cover (the bezel filler will not disengage from the server if the
cover is locked).

4. Grasp the recessed area on the bezel filler and rotate the bezel filler outward
until it disengages from the server.

Chapter 4. Customer replacement units 43

5. Touch the static-protective package containing the drive to any unpainted metal
surface on the server; then, remove the drive from the package and place it on
a static-protective surface.

6. Align the drive assembly with the guide rails in the bay (the connector end of
the drive goes in first); then, gently slide the drive assembly all the way into the
drive bay until you hear a click.

7. If you have other options to install or remove, do so now. Otherwise, replace the
bezel filler; then, see “Completing the installation” on page 60.

Power and signal cables for internal drives

The server uses cables to connect parallel IDE, simple-swap Serial ATA, and SCSI
devices to the power supply and to the system board (see “System board internal
connectors” on page 86 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 or label which cable is attached to
which drive.

v When you install a drive, make sure that one of the signal cable drive connectors

is connected to the drive and that the connector at the other end of the signal
cable is connected to the system board.

v If you have only one IDE device on a cable, it must be set as a master device.
v If two IDE devices are used on a single cable, one must be designated as the

master device and the other as the subordinate device; otherwise, the server
might not recognize some of the IDE devices. The master and subordinate
designation is determined by switch or jumper settings on each IDE device.

44 xSeries 226 Type 8488 and 8648: Hardware Maintenance Manual and Troubleshooting Guide

The following cables are provided:

v Power cables: Four-wire power cables connect the drives to the power supply.

At the end of these cables are plastic connectors that can be attached to
different drives; these connectors vary in size. Use either a four-wire power cable
or Serial ATA power cable with Serial ATA drives, but do not use both at the
same time (use one or the other). For SCSI hot-swap drives, a special power
cable connects the SCSI backplane to the power supply.

v Signal cables: Signal cables are typically flat cables, also called ribbon cables,

that connect parallel IDE, Serial ATA, SCSI, and diskette drives to the system
board. Two or three types of signal cables come with the server:

– IDE: The wider IDE signal cable has three connectors. One of these

connectors is attached to the drive, one is a spare, and the third is attached to
the primary IDE connector on the system board. The spare connector can be
used to connect an additional IDE drive to the server.

The CD-ROM drive is attached to an ATA 100 signal cable. ATA 100 signal
cables are color-coded. The blue connector is attached to the system board.
The black connector is attached to the master IDE device. The gray middle
connector is attached to the subordinate IDE device.

– Diskette drive: The narrower signal cable has two connectors. One is

attached to the diskette drive, and the other is connected to the connector
(FDD1) on the system board.

– Serial ATA (SATA): The narrower, black signal cable has two connectors. One

is connected to a simple-swap Serial ATA drive, and the other is attached to
the connector on the system board. Each simple-swap Serial ATA drive comes
with a cable. If you install an additional simple-swap Serial ATA drive, you will
need an additional cable.

If you install the optional ServeRAID-7t S-ATA controller to add a third and
fourth SATA drive, all four SATA drives must then be connected to the
ServeRAID-7t S-ATA controller instead of the system board. The optional
ServeRAID-7t S-ATA controller comes with two cables that you can use to
cable the third and fourth SATA drives. See the optional ServeRAID-7t S-ATA
controller documentation for cabling instructions.

– SCSI: A round SCSI cable connects the SCSI backplane to the SCSI channel

B connector on the system board. The maximum cable length that supports
Ultra320 SCSI hard disk drives is 61 cm (24 in.).

Installing an external SCSI connector

To install an external SCSI connector on the rear of the server, install an external
SCSI interface option. For a list of supported external SCSI interface options for the
server, go to http://www.ibm.com/pc/compat/.

The external SCSI interface option contains a SCSI cable with a connector at one
end and another connector on the other end. Complete the following steps to install
and route the SCSI cable in the server:

1. Turn off the server and all peripheral devices. Disconnect all power cords;
then, disconnect all external signal cables from the server.

2. Remove the server cover (see “Removing the side cover” on page 28).

3. Remove the support bracket (see “Removing and installing the support
bracket” on page 32).

Chapter 4. Customer replacement units 45

4. Open the front adapter-support bracket and remove the rear adapter-retention
bracket from the PCI-X slots (see “Installing an adapter” on page 51 for
instructions). Yo u might also have to remove longer adapters for access to the
SCSI connectors on the system board.

5. Connect the SCSI signal cable end labeled “PLANAR” to the connector for
SCSI channel B on the system board (see “System board internal connectors”
on page 86 for the location of the SCSI channel B connector).

6. Route the SCSI cable to the adapter slot that has the special SCSI-knockout
slot cover on the back of the server (see “Connecting the cables” on page 61
for an illustration of the SCSI-knockout slot cover, normally in PCI slot 3).
Make sure the cable does not block the flow of air to the hard disk drives.

Note: You can move the special SCSI-knockout slot cover to a different slot if

needed.

7. Remove the SCSI-connector knockout from the PCI-X slot cover; then, insert
the external SCSI connector on the SCSI cable into the knockout opening and
secure it with the attached screws.

8. Replace any adapters you removed in step 4. Close the front adapter-support
bracket and replace the rear adapter-retention bracket.

9. Replace the support bracket (see “Removing and installing the support
bracket” on page 32).

10. Replace the cover (see “Replacing the side cover” on page 29).

11. Reconnect the external cables and power cords. Turn on the attached devices,
and turn on the server.

12. Use the SCSISelect program to configure SCSI channel B (see the User’s

Guide for information about using the SCSISelect program).

Installing an additional 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 and supports up to two

microprocessors.

v Read the documentation that comes with the microprocessor to determine

whether you must update the basic input/output system (BIOS) code in the
server. To download the most current level of BIOS code for the server, go to
http://www.ibm.com/pc/support/.

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

operating systems, go to http://www.ibm.com/pc/compat/.

v The microprocessors must have the same cache size and type, and the same

clock speed. Microprocessor internal and external clock frequencies must be
identical. Yo u can use the Configuration/Setup Utility program to determine the
specific type of microprocessor that is in the server.

v Terminator cards are not required for empty microprocessor sockets. However,

for airflow, an empty microprocessor socket must contain a microprocessor
baffle.

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 The system board contains an integrated voltage regulator for microprocessor 1;

you must install a voltage regulator module (VRM) on the system board when
you install microprocessor 2. The VRM comes in the microprocessor option kit.

v These instructions assume that you are installing microprocessor 2.

Updating the server configuration

When you start the server for the first time after you add or remove an internal
option or an external SCSI device, you might receive a message that the
configuration has changed. The Configuration/Setup Utility program starts
automatically so that you can save the new configuration settings. See the User’s

Guide for additional information.

Some options have device drivers that you must install. See the documentation that
comes with each option for information about installing device drivers.

If the server has a ServeRAID adapter installed and you have installed or removed
a hard disk drive, see the ServeRAID documentation that comes with the server for
information about reconfiguring the disk arrays.

Connecting external options

If you install an optional SCSI adapter, you can attach external SCSI devices, such
as a SCSI storage expansion enclosure, to the server.

Note: If the server model supports internal (simple-swap) SATA hard disk drives,

installing an optional SCSI adapter enables you to add only external SCSI
tape drives to the server.

Complete the following steps to attach an external device:

1. Review Appendix B, “Safety information,” on page 143, “Installation guidelines”
on page 25, and the documentation that comes with the option.

2. Turn off the server and all attached devices.

3. Follow the instructions that come with the option to prepare it for installation and
to connect it to the server.

If you are attaching an external SCSI device, see “Ultra320 SCSI connector”

Enhanced Parallel Port (EPP), and Extended Capability Port (ECP). If you configure
the parallel port to operate in bidirectional mode, it supports the ECP and EPP
modes of operation. To configure the parallel port, use the Devices and I/O Ports
option in the Configuration/Setup Utility program (see “Starting the
Configuration/Setup Utility program” on page 10). If you configure the parallel port
to operate in bidirectional mode, use an IEEE 1284-compliant cable that does not

Ultra320 SCSI connector

You can install up to four internal SCSI devices in some models of the server.
These models come with one SCSI cable that is connected from the internal SCSI
connector to the standard hot-swap-drive backplane. Yo u can attach additional
internal SCSI devices to the other internal SCSI connector, or you can use the
connector to attach external SCSI devices. To connect external SCSI devices,
remove the SCSI knockout from the rear of the server and secure the free end of
an optional cable in the new opening.

If you want to attach external SCSI devices to the server without using the internal
SCSI channel, you must install an optional SCSI adapter.

Notes:

1. External SCSI devices connected to internal SCSI channel will operate
asynchronously.

2. 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 an optional
SCSI adapter” on page 54).

optional external SCSI connector might be installed on the rear of the server.

The server has a dual-channel SCSI controller. This dual-channel controller
supports two independent, Ultra320 SCSI channels that support up to 15 SCSI
devices each. The SCSI connectors for the channels are on the system board. The
controller has the following features:

v Double-transition clocking to achieve up to 320 MBps (megabytes per second)

data-transfer rates

v Domain name validation to negotiate compatible data-transfer speeds with each

device

v Cyclic-redundancy checking (CRC) to improve data reliability
v An active terminator for SCSI bus termination

SCSI device that is connected to a SCSI controller must have a unique SCSI

Each
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.

68

35

Chapter 4. Customer replacement units 65

The hot-swap-drive backplane controls the SCSI IDs for the internal hot-swap drive
bays. However, when you attach an external SCSI device to an optional SCSI
adapter, you must set a unique ID for the device. See the information that comes
with the device for instructions to set its SCSI ID.

You can attach external SCSI devices using an optional SCSI adapter. To select
and order the correct adapter for use with external devices, contact your IBM
marketing representative or authorized reseller. When using an optional SCSI
adapter, you must also connect the SCSI adapter to the SCSI LED connector on
the system board to receive an indication of SCSI hard disk drive activity.

Note: On server models that support SATA hard disk drives, you can attach only an

external SCSI tape drive to an optional SCSI adapter.
See “System board internal connectors” on page 86 for the location of the SCSI
connectors. For information about the maximum length of SCSI cable, see the
American National Standards Institute (ANSI) SCSI standards on the ANSI Web site
at http://www.ansi.org/. Adhering to these standards will help to ensure that the
server operates correctly.

Universal Serial Bus connectors

Use a Universal Serial Bus (USB) 2.0 connector to connect a USB device. USB 2.0
technology transfers data at up to 480 Mb per second (Mbps) with a maximum of
127 devices and a maximum signal distance of 5 meters (16 ft) per segment (if the
device that is attached to the server is a USB 2.0 device). If multiple USB devices
are attached to the server, the USB hub must be 2.0; otherwise, all USB 2.0
devices will transfer data at 12 Mbps. Using Plug and Play technology, USB devices
are configured automatically. The following illustration shows a USB connector.

14

Use a 4-pin cable to connect a device to a USB connector. If you need to connect
more USB devices than the server has USB connectors for, use a USB hub to
connect additional devices.

If you connect a PS/2 (non-USB) keyboard to the keyboard connector, USB ports
and devices are disabled during POST.

If you connect a USB keyboard that has a mouse port, the keyboard emulates a
mouse, and you cannot disable the mouse settings in the Configuration/Setup Utility
program.

Video connector

Use the video connector to connect a monitor to the server. The connector is dark
blue to help you identify it. The following illustration shows an industry-standard
15-pin analog video connector on the rear of the server.

Removing the system board

Before you begin:

v Read Appendix B, “Safety information,” on page 143.
v Review the information in “System reliability guidelines” on page 25.

Notes:

1. When replacing the system board, you must either update the server with the

latest firmware or restore the pre-existing firmware that the customer provides
on a diskette or CD image.

2. Removing the system board will be easier if the server is turned on its side.

To remove the system board, complete the following steps:

1. Turn off the server, if it is on.

2. Disconnect the power cord from the power source and from the server; then,
disconnect all external cables.

3. Remove the side cover (see “Removing the side cover” on page 28).

4. Remove the frame-support bracket (see “Removing and installing the support
bracket” on page 32).

5. Remove the microprocessor air baffle (see “Microprocessor air baffle” on page

67).

6. Disconnect the cables.

7. Remove both adapter-retaining brackets and the adapters (see “Installing an
adapter” on page 51).

8. Remove memory modules (see “Installing a memory module” on page 34).

9. Remove the microprocessors (see “Microprocessor and heat sink” on page

68).

10. Remove the VRM if one is installed (see “Installing an additional
microprocessor” on page 46 for the location of the VRM).

11. Remove the front fan housing.
