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, and hard
drives. 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 “POST error codes” on page 93.

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

on page 102.

5. Power supply problems, see “Power supply LED errors” on page 92.

6. Safety information, see “Safety information” on page 109.

7. For intermittent problems, check the error log; see “Error logs” on page 12.

Server features

The xSeries 342 is designed to be cost-effective, powerful, and flexible. The server
offers:

v Impressive performance using an innovative approach to SMP

The server supports up to two Intel Pentium III microprocessors. The server

comes with one microprocessor installed; you can install an additional

microprocessor to enhance performance and provide SMP capability.
v Large data-storage and hot-swap capabilities

All models of the server support up to three hot-swap hard disk drives. This

hot-swap feature enables you to remove and replace hard disk drives without

turning off the server. The xSeries 3-Pack Ultra 160 Hot-Swap Expansion Kit

option is available to add three additional drives.
v Optional PCI adapters

The server uses peripheral component interconnect (PCI) bus architecture to

provide compatibility with a wide range of existing hardware devices and software

applications. The server supports up to five PCI adapters in the expansion slots

on the system board.
v Redundant cooling capability

The redundant cooling capability of the hot-swap fans in the server allow

continued operation if one of the fans fails. You can also replace a failing

hot-swap fan without turning off the server.
v Optional redundant power capability

You can install an additional 270-watt power supply in the server to provide

redundant power for the server. The Power Non-Redundant (NON) light emitting

diode (LED) in the group of diagnostic LEDs on the system board is lit when the

power load is 270 watts or greater with two power supplies installed.
v Large system memory

The memory bus in the server supports up to 4 GB (GB equals approximately

1000000000 bytes) of system memory. The memory controller provides error

correcting code (ECC) support for up to four industry standard PC133, 3.3 V,

168-pin, 8-byte, registered, synchronous-dynamic-random access memory

(SDRAM) dual inline memory modules (DIMMs).
v IBM integrated system management processor (ISMP)

The integrated system management processor provides environmental monitoring

for the server. When environmental conditions exceed thresholds or when system

components fail, the ISMP lights the Light Path Diagnostics

™

LEDs to indicate
the location of the problem. Critical errors, as well as environmental and
configuration information, are also included in the error log.

If an optional Remote Supervisor Adapter is installed on the Advanced System
Management (ASM) interconnect network, you can view the system health;
update the ISMP code; power on, power off, and restart the server; view the error
log; view the vital product data; and send alerts over the ASM interconnect
network.

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

v Redundant network-interface card

General information 5

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 Optional digital linear tape drive

The addition of an optional digital linear tape drive (DLT) allows quick backup of
large amounts of data.

™

v IBM ServerGuide

CDs

The ServerGuide CDs included with the server 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 programs and device drivers. In addition, the ServerGuide CDs
include a variety of application programs for the server.

Reliability, availability, and serviceability features

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.

Diagnostics

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

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” on page 12
for more information.

v 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. See “Diagnostic programs and error
messages” on page 13 for more information.

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” for more
information.

Identifying problems using LEDs

The server has LEDs to help you identify problems with some server components.
These LEDs are part of the light path diagnostics built into the server. By following
the path of lights, you can identify the type of system error that occurred. See the
following sections for more information.

Power supply LEDs

The AC and DC Power LEDs on the power supply provide status information about
the power supply. See “Power supply LED errors” on page 92.

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 diagnostics panel is under the air baffle.
The server is designed so that any LEDs that are illuminated remain illuminated
when the server shuts down as long as the AC power source is good and the
power supplies can supply +5V DC current to the server. This feature helps you
isolate the problem if an error causes the server to shut down. See “Light path
diagnostics” on page 12.

Diagnostics panel

The following illustration shows the LEDs on the diagnostics panel on the system
board. See “Light path diagnostics” on page 12 for information on identifying

Light path diagnostics

The System Error LED on the operator information panel is lit when certain system
errors occur. If the System Error LED on the server is lit, see the table in
“Information panel system error LED” on page 85 to determine the cause of the
error and the action you should take.

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.

REMIND

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 and an error message
appears on the screen. See “Beep symptoms” on page 83 and “POST error
messages” for more information.

Notes:

1. If you have a power-on password or administrator password set (with Remote
Supervisor Adapter installed), 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 error messages

The table “POST error codes” on page 93 provides information about the POST
error messages that can appear during startup.

Error logs

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
issued during POST and system status messages from the integrated system
management processor.

12 Hardware Maintenance Manual: xSeries 342 Type 8669

Note: It is possible during power-on that some system error log entries may

contain a date of 01/01/1990 with a time of 00:00:00. These entries occur
prior to the ISMP clock being initialized and may be disregarded.

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

Log viewing from Configuration/Setup

To view the contents of the error log from the Configuration/Setup Utility, start the
Configuration/Setup Utility program; then, select Error Logs from the main menu.

following list to determine the possible cause of the error and what action to take.

Note: If the server does not have a hard disk drive, ignore any message that

indicates that the drive is not installed.

One or more of the following might be causing the problem.

v A failing SCSI device (adapter or drive)
v An improper SCSI configuration
v Duplicate SCSI IDs in the same SCSI chain
v An improperly installed SCSI terminator
v A defective SCSI terminator
v An improperly installed cable
v A defective cable

Verify that:
v The external SCSI devices are turned on. External devices must be turned on

before the server.

v The cables for all external SCSI devices are connected correctly.
v The last device in each SCSI chain is terminated properly.
v The SCSI devices are configured correctly.

You will get these messages only when running the SCSISelect Utility. See “SCSI
error codes” on page 99.

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.

Diagnostics 13

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.

Text messages

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.

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.

14 Hardware Maintenance Manual: xSeries 342 Type 8669

Diagnostic error message tables

For descriptions of the error messages that might appear when you run the
diagnostic programs, see “Diagnostic error codes” on page 87.

Attention: If diagnostic error messages appear that are not listed in the tables,
make sure that the server has the latest levels of BIOS, Integrated System
Management Processor, ServeRAID, and diagnostics microcode installed.

Recovering BIOS code

If the BIOS code has become damaged, 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:

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

The flash memory of the server contains a protected area that cannot be
overwritten. The recovery boot block is a section of code in this protected area that
enables the server to start up and to read a flash diskette. The flash utility recovers
the system BIOS from the BIOS recovery files on the diskette.

To recover the BIOS:

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

2. Locate the boot-block jumper block (J16) on the system board.

3. Place a jumper on pins 2 and 3 to enable BIOS backup page.

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

5. Restart the server.

http://www.ibm.com/pc/support/ and make the appropriate selections.

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.

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 bad
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.

Diagnostics 17

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

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

If the testing methods above indicate that the hardware is functioning normally
but the problem still exists, inform the network administrator.

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 1. 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.

If the problem remains, go to “Starting the diagnostic programs” on page 15 to run
the diagnostic programs.

Ethernet Link Status light
does not light.

The Ethernet
Transmit/Receive Activity light
does not light.

Data is incorrect or sporadic. Check the following:

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.

If the problem remains, go to “Starting the diagnostic programs” on page 15 to run
the diagnostic programs.

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.

Table 1. Ethernet troubleshooting chart (continued)

Ethernet controller problem Suggested Action

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 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.

If the problem remains, go to “Starting the diagnostic programs” on page 15 to run
the diagnostic programs.

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.

If the problem remains, go to “Starting the diagnostic programs” on page 15 to run
the diagnostic programs.

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 103).

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 103). For specific problems, see “Power error
messages” on page 100.

Replacing the battery

When replacing the battery, you must replace it with a lithium battery of the same
type from the same manufacturer. To avoid possible danger, read and follow the
safety statement below.

To order replacement batteries, call 1-800-772-2227 within the United States, and
1-800-465-7999 or 1-800-465-6666 within Canada. Outside the U.S. and Canada,

Remind Button

Installing options 39

You can use the Remind button to place the front panel system-error light into a
Remind mode. By pressing the button, you acknowledge the failure but indicate that
you will not take immediate action. If a new failure occurs, the LED will turn on
again.

In the Remind mode, the system-error light flashes every 2 seconds. The
system-error light remains in Remind mode until one of the following situations
occur:

v All known problems are resolved
v The system is restarted
v A new problem occurs

You can use the Remind button to delay server maintenance until a later time. Also,
resetting the system-error light enables the LED to react to another error. If the LED
is still solid from the first error, it will mask additional errors.

Integrated System Management Processor LED

The xSeries 342 server has an Integrated System Management Processor feature
on the system board. The green Integrated System Management Processor LED
flashes, indicating that the system temperature, fan speeds, voltage ranges, power
supplies, power backplane, and DASD backplane are being monitored. If an error
occurs in any of these areas, the Integrated System Management Processor turns
on the respective error LED on the Light Path Diagnostics panel. If the Integrated
System Management Processor LED remains on or off, or if it blinks significantly
faster than approximately once per second, then an error has occurred. See ″SP
LED″ at “Information panel system error LED” on page 85.

System reliability considerations

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

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

operating.

v The processor housing cover (if available on the server) that protects the

processor and memory area is removed for no longer that ten minutes while the
server is operating.

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

with the adapters (ensure that cables are not restricting air flow).

v The fans are operating correctly and the air flow is good.
v A failed fan is replaced within 48 hours.

In addition, ensure that the environmental specifications for the system are met.
See “Features and specifications” on page 3.

For information on temperature error messages, see “Temperature error messages”
on page 99.

Working inside a server with power on

The server supports hot-plug, hot-add, and hot-swap devices and it 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, and loose-fitting wrist watches.
v Remove items from your shirt pocket (such as pens or pencils) that could fall into

the server as you lean over it.

v Take care to 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.

Installing options 41

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.

components.

To remove the bezel:

1. Press in on the top sides of the bezel and pull the bezel away from the server
front.

2. Store the bezel in a safe place.

You can install up to five peripheral component interconnect (PCI) adapters in the
expansion connectors on the system board.

The server comes with a video controller. This video controller is an integrated
component on the system board. It is not removable. If you want to disable this
controller and use a video adapter instead, you can install a video adapter in an
expansion slot. When you install a video adapter, the server BIOS automatically
disables the integrated video controller.

Adapter considerations

Before you continue with the adapter-installation procedure:
v Review the documentation that comes with the adapter and follow those

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

v You can install full-length adapters in all expansion slots.
v You can install a 32-bit adapter in any of the PCI slots.
v The server supports 5.0 V signalling and universal PCI adapters in slots 1, 2, and

3; it supports 3.3 V signalling or PCI adapters in slots 4 and 5.

44 Hardware Maintenance Manual: xSeries 342 Type 8669

v The server uses a rotational interrupt technique to configure PCI adapters.

Because of this technique, you can install a variety of PCI adapters that currently
do not support sharing of PCI interrupts.

v PCI slot 1 is on PCI bus A, PCI slots 2 and 3 are on PCI bus B, and PCI slots 4

and 5 are on PCI bus C. The system scans PCI slot 1, the system board
Ethernet, PCI slots 2-5, the system board SCSI, channel A, and the system
board SCSI channel B, if you have not changed the boot precedence from the
default.

You can use the Configuration/Setup Utility program to change the boot
precedence for the server. Select Start Options from the Configuration/Setup
Utility program.

Note: The Remote Supervisor Adapter must be installed in PCI slot 1.

connector A (J24)

To install an adapter:

1. Review the information in “Before you begin” on page 40.

2. Turn off the server and peripheral devices and disconnect all external cables
and power cords; then, remove the cover (see “Removing the cover and bezel”

on page 42).

3. Determine which expansion slot you will use for the adapter.
Attention: Check the instructions that come with the adapter for any

requirements or restrictions.

4. Remove the expansion-slot cover:
a. Loosen and remove the screw on the top of the expansion-slot cover.
b. Slide the expansion-slot cover out of the server. Store it in a safe place for

future use.
Attention: Expansion-slot covers must be installed on the openings for

all vacant slots. This maintains the electromagnetic emissions
characteristics of the system and ensures proper cooling of system
components.

5. Refer to the documentation that comes with your adapter for any cabling
instructions. It might be easier for you to route any cables before you install
the adapter.

6. Remove the adapter from the static-protective package.

Attention: Avoid touching the components and gold-edge connectors on the

7. Place the adapter, component-side up, on a flat, static-protective surface.

8. Set any jumpers or switches as described by the adapter manufacturer.

9. Install the adapter:
a. Carefully grasp the adapter by its top edge or upper corners, and align it

with the expansion slot on the system board.

b. Press the adapter firmly into the expansion slot.

adapter.

Internal drives

Attention: When you install an adapter in the server, be sure that it is

completely and correctly seated in the system-board connector
before you apply power. Incomplete insertion might cause
damage to the system board or the adapter.

c. Insert and tighten the expansion-slot screw on the top of the adapter

bracket.

10. Connect any needed cables to the adapter.
v If you are installing a ServeRAID adapter, disconnect the cable from SCSI

connector A (J24) on the system board and plug it into the connector on the
top of the ServeRAID adapter.

v If you are installing an adapter that is not a ServeRAID adapter, refer to the

documentation that came with your adapter for cabling instructions.

Attention: Route cables so that the flow of air from the fans is not blocked.

11. If you have other options to install or remove, do so now; otherwise, go to

“Installing the server cover and bezel” on page 64.

If you add different types of drives, your 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 Tape

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

Each hot-swap drive bay has two indicator lights (see “Controls and indicators” on
page 7). If the amber hard-disk status light is lit continuously, that individual drive is
faulty and needs to be replaced. When the hard-disk status light indicates a drive
fault, you can replace that hot-swap drive without turning off the server.

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

Internal drive bays

Internal drives are installed in bays. The server comes with a preinstalled diskette
drive and a preinstalled CD-ROM drive.

Installing options 47

v The server comes with one 3.5-inch, 1.44 MB diskette drive and one 48x IDE

CD-ROM drive.

v The empty bays below the diskette drive come without a device installed. You

can use these bays for 5.25-inch, half-high, removable-media drives, such as
tape backup drives. You also can combine these bays into a single, full-high bay
and install a digital linear tape (DLT) drive; or, you can install an xSeries Media
Bay Ultra 160 Hot Swap Conversion Kit option, which converts these bays to
three hot-swap drive bays.

v The xSeries 342 server supports only one diskette drive.
v If you are installing a device with a 50-pin connector in either of the 5.25-inch

bays, you need a 68-pin to 50-pin converter (option number 32G3925).

v The server supports three slim-high (1-inch) hot-swap hard disk drives in the

hot-swap bays. If the server has the xSeries Media Bay Ultra 160 Hot Swap
Conversion Kit option installed, it supports three additional hot-swap hard disk
drives.

v The hot-swap bays connect to a SCSI backplane. This backplane is a printed

circuit board behind the bay.

Note: The server EMI integrity and cooling are both protected by having the

5.25-inch bays covered or occupied. When you install a drive, save the filler
panel from the bay, in case you later remove the drive and do not replace it
with another.

SCSI drives

Some drives have a special design called small computer system interface,or
SCSI. This design allows you to attach multiple drives to a single SCSI channel.

Notes:

1. Any information about SCSI drives also applies to other SCSI devices, such as
tape drives.

2. If you plan to install both internal and external SCSI devices, you must follow
the instructions in “Connecting external options” on page 65, in addition to the
instructions in this section.

A 16-bit (wide) SCSI cable connects the SCSI hard-disk drive backplane to an
integrated SCSI controller on the system board. An additional 16-bit 1-drop SCSI
cable is shipped inside the server. It is folded and restrained with a cable clamp on
the bottom of the server chassis near the empty bays. You can use this cable to
connect an optional SCSI device installed in one of the empty 5.25-inch bays to the
SCSI channel A connector on the system board.

SCSI IDs

Each SCSI device that is connected to an individual channel of a SCSI controller
needs a unique identification (ID) so that the controller can identify the devices and
ensure that different devices do not attempt to transfer data at the same time. If you
need to set IDs for SCSI devices, refer to the instructions that come with those
devices.

The server automatically sets SCSI IDs for hot-swap hard disk drives.

The SCSI ID assigned to each hot-swap bay is shown on the server beside the bay.
The server uses the hard disk drive SCSI IDs to send status information to the
indicator lights above each hot-swap bay.

48 Hardware Maintenance Manual: xSeries 342 Type 8669

The processing sequence for SCSI devices is set through the SCSISelect Utility
program. The default sequence proceeds from the lowest SCSI ID to the highest (0
to 15). The SCSI controller uses ID 7.

Ensure that the device you are installing is not terminated. It is not necessary to set
termination jumpers on internal SCSI devices. The server hardware provides
termination for all internal SCSI devices.

Hot-swap drive installation

The hot-swap drive bays support hot-swap drives only.

This section gives the procedure for installing a hot-swap hard disk drive. If you
want to remove a drive, reverse the following steps.

Notes:

1. To minimize the possibility of damage to the hard disk drives, install the server
in the rack before installing the hard disk drives.

2. You do not have to turn off the server to install hot-swap drives. However, you
must turn off the server when performing any steps that involve installing or
removing cables.

Drive-tray assembly

Drive handle

Filler panel

To install a drive in a hot-swap drive bay:

1. Review the information in “Before you begin” on page 40.

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

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

2. Remove the filler panel from one of the empty hot-swap bays by inserting your
finger into the depression on the filler panel and pulling it away from the server.

3. Install the hard disk drive in the hot-swap bay:
a. Ensure the tray handle is open (that is, perpendicular to the drive).
b. Align the drive/tray assembly with the guide rails in the bay.
c. Gently push the drive/tray assembly into the bay until the drive connects to

the backplane.

d. Push the tray handle down until it locks.

Installing options 49

4. Check the hard disk drive status indicators to verify that the hard disk drive is
operating properly.

Non-hot-swap drive installation

Before you install drives in the server, verify that you have all the cables and any
other equipment specified in the documentation that comes with the internal drive.
You might also need to perform certain preinstallation activities. Some of the steps
are required only during the initial installation of an option.

To install a non-hot-swap drive:

1. Review the information in“Before you begin” on page 40.

2. Turn off the server and peripheral devices and then remove the cover and
bezel. (See “Removing the cover and bezel” on page 42.)

3. Remove the filler panel from the bay opening by pushing in the side latches
and pulling the filler panel away from the server. You do not need the filler
panel when you have a drive installed in the bay.

Note: The electromagnetic interference (EMI) integrity and cooling are

protected by having the non-hot-swap bays covered or occupied. When
you install a drive, save the filler panel from the bay, in case you later
remove the drive and do not replace it with another.

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

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

6. Install rails on the drive.
v If you are installing a standard-size drive:

a. Pull the blue slide rails off the back of the filler panel.
b. Clip the rails onto the sides of the drive.

v If you are installing a digital linear tape (DLT) backup drive, use the metal

slide rails and screws that are shipped in the box that contains the server
documentation.

7. Place the drive so that the slide rails engage in the bay guide rails. Push the
drive into the bay until it clicks into place.

8. If you are installing a SCSI device, continue with the next step. If you are
installing an IDE device, go to step 11.

9. To install a SCSI device:
a. Attach the connector on the 1-drop SCSI cable for the non-hot-swap drive

bays to the back of the drive. The cable is shipped restrained in a cable
clamp on the bottom of the server chassis near the bays. Connect the
other end of the cable to SCSI channel A on the system board, if it is not
already attached. See “System board internal cable connectors” on
page 35 for the location of the SCSI channel A connector.

Note: If you want to install more than one optional SCSI 5.25-inch device,

install an optional SCSI adapter to control the device.

b. Connect a power cable to the back of the drive. Power cables for

non-hot-swap drives come installed in the server. The connectors are
keyed and can be inserted only one way.

c. Continue with step 11

10. To install an IDE device, such as a CD-ROM drive or a DVD-ROM drive, use
the two-drop IDE cable that comes with the option:

a. Remove the cable connecting the CD-ROM drive to the IDE connector on

the system board.

b. Using the two-drop cable that came with your IDE option, connect the

CD-ROM drive and the IDE device to the IDE connector on the system
board.

c. Set the jumper on the back of the new IDE device to slave.

11. If you have other options to install or remove, do so now; otherwise, go to

“Installing the server cover and bezel” on page 64.

Memory modules

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 options called
memory-module kits. Each kit contains one industry-standard, dual inline memory
module (DIMM). The server uses a two-way interleaved memory configuration. You
must install matched pairs of memory kits, but the set in slots 1 and 4 do not need
to be the same size as the set in slots 2 and 3.

Notes:

1. The server comes with two dual inline memory modules (DIMMs) installed in

2. Your xSeries 342 server supports 128 MB, 256 MB, 512 MB, and 1 GB DIMMs.

3. Installing or removing DIMMs changes the configuration information in the

DIMM slots 1 and 4. Install additional DIMMs as a matched pair in DIMM
connectors 2 and 3 and as instructed in the documentation that comes with your
option.

You must install the DIMMs in pairs of the same size. Place pair 1 in slots 1 and
4 and pair 2 in slots 2 and 3. Refer to the ServerProven

and then the other edge of the DIMM. Be sure to press straight into the
connector. Be sure that the retaining clips snap into the closed position.

c. Make sure the retaining clips are in the closed position. If a gap exists

between the DIMM and the retaining clips, the DIMM has not been properly
installed. In this case, open the retaining clips and remove the DIMM; then,
reinsert the DIMM.

d. Repeat steps 5a through 5c for the second DIMM; then continue with step 6.

6. If you have other options to install or remove, do so now; otherwise, go to
“Installing the server cover and bezel” on page 64.

Microprocessor installation

The server comes with one microprocessor installed on the system board. If you
install an 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 between the microprocessors.

Notes:

1. Before you install a new microprocessor, 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.

2. 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.

channels: one internal and one external. Each of these channels supports up to 15
SCSI devices. In addition, this controller uses:

v Double-transition clocking to achieve high transfer rates
v Domain name validation to negotiate compatible data transfer speeds with each

device

v Cyclic-redundancy checking (CRC), instead of the usual parity checking, to

significantly improve data reliability

v An active terminator on the system board for SCSI bus termination

Installing options 67

You can use the external LVD SCSI channel connector, on the rear of the server, to
connect different types of small computer system interface (SCSI) devices. Inside
the server, a SCSI cable connects the internal SCSI channel connector to the
hot-swap drive backplane.

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.

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 hot-swap-drive backplane controls the SCSI IDs for the internal hot-swap drive
bays. However, when you attach SCSI devices to the external SCSI connector, you
must set a unique ID for the device. Refer to the information that is provided with
the device for instructions to set its SCSI ID.

Serial ports

The server has two standard serial ports, Serial port A and Serial port B. The
operating system can use both serial ports, Serial port A and Serial port B.

Some application programs require specific ports, and some modems function
properly only at certain communication port addresses. You might need to use the
Configuration/Setup Utility program to change communication port address
assignments to prevent or resolve address conflicts.

Viewing or changing the serial-port assignments: To view or change the
serial-port assignments:

1. Restart the server and watch the monitor screen.

2. When the message Press F1 for Configuration/Setup appears, press F1.

3. From the main menu, click Devices and I/O Ports; then, press Enter.

4. Select the serial port; then, use the arrow keys to advance through the settings
available.

5. Select Save Settings; then, select Exit Setup to exit from the
Configuration/Setup Utility main menu.

Serial-port connectors: The following table shows the pin-number assignments

Universal Serial Bus ports

The server has two Universal Serial Bus (USB) ports, which configure automatically.
USB is an emerging serial interface standard for telephony and multimedia devices.
It uses Plug and Play technology to determine the type of device attached to the
connector.

Notes:

1. If you attach a standard (non-USB) keyboard to the keyboard connector, the
USB ports and devices will be disabled during the power-on self-test (POST).

2. If you install a USB keyboard that has a mouse port, the USB keyboard
emulates a mouse and you will not be able to disable the mouse settings in the
Configuration/Setup Utility program.

USB cables and hubs: You need a 4-pin cable to connect devices to USB 1 or
USB 2. If you plan to attach more than two USB devices, you must use a hub to
connect the devices. The hub provides multiple connectors for attaching additional
external USB devices.

USB technology provides 12 megabits-per-second (Mbps) speed with a maximum
of 127 external devices and a maximum signal distance of five meters (16 ft.) per
segment.

USB-port connectors: Each USB port has an external connector on the rear of
the server for attaching USB compatible devices.

Ethernet port

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.

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 Netfinity 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 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, all Ethernet traffic associated with it is switched to
the redundant (secondary) controller. 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 Netfinity

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 (this system does not have a hot-plug PCI), 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.

Installing options 71

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 Novell 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 73.

Windows NT Server hot-plug setup:

IBM Netfinity Hot Plug PCI for Windows NT Server 4.0 package is available for
download from the IBM Web site at:

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

Enter the brand type of Server, click on Downloadable files and look for Hot Plug.
The IBM Netfinity Hot Plug PCI for Windows NT Server 4.0 package uses the Intel
Desktop Management Interface (DMI) to control hot-plug support for the Ethernet
controllers. The Ethernet controller in your computer is DMI compliant. Download
and install the following software in the order listed:

1. IBM Failover DMI Agent

2. IBM PCI Hot Plug Solution

3. IBM Netfinity 10/100 Fault Tolerant Adapter device drivers

Note: The order of installation is important. You must install the IBM Netfinity Hot

Plug for Windows NT.

Note: The order of installation is important. You must install the IBM Netfinity Hot

Plug for Windows NT Server 4.0 package before you install the IBM Netfinity
10/100 Fault Tolerant Adapter driver. If you install the adapter device driver
before the PCI Hot Plug Solution package, the adapter device driver will not
recognize the hot-plug code. This happens because the adapter device
driver only checks the NT registry for the Hot Plug package during
installation. If the PCI Hot Plug Solution package is added after the adapter
device driver is installed, the adapter must be removed and added again in
order for it to detect the PCI Hot-Plug Solution code.

To install the IBM Failover DMI Agent:

1. Download the DMI EXE file from the xSeries Support web page and extract the
files onto a diskette.

2. Insert the diskette into the diskette drive.

3. From the Start menu, select the Run option.

4. Type A:\SETUP.EXE in the Open box.

5. Click Ok. The setup wizard opens.

6. Follow the instructions that are given by the setup wizard until the program is
installed.

7. Restart the server.

72 Hardware Maintenance Manual: xSeries 342 Type 8669

To install the IBM PCI Hot Plug Solution package:

1. Download the IBM PCI Hot Plug Services EXE file from the xSeries Support
web page and extract the files onto a diskette.

2. Log on to Windows NT Server as a user in the Administrator group.

3. Insert the diskette into the diskette drive.

4. From the Start menu, select the Run option.

5. Type A:\SETUP.EXE in the Open box.

6. Click OK. The Setup wizard opens.

7. Follow the instructions given by the setup wizard until the program is installed.

Windows NT Server failover setup:

To install the IBM Netfinity 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 bus A, slot 2.

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
Netfinity 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 Netfinity 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.

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 Netfinity 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:

Installing options 73

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

2. Load the device driver by using the following command:

LOAD d:\path\PCNTNW.LAN PRIMARY=x SECONDARY=y

where d and path are the drive and path where the driver is located, and x and
y are the PCI slot numbers where the redundant pair is located.

The slot number associated with the integrated Ethernet controller can vary
depending on the configuration of the server. To determine the slot number, load
the driver with no parameters. The driver will display the available slot numbers.
The slot number that is greater than 10000 will be the slot number of integrated
Ethernet controller. When the slot number of the integrated Ethernet controller is
determined, reload the driver with the appropriate parameters.

3. When the driver is loaded, bind it to a protocol stack.

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.
