General checkout

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

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

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

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

A system might be part of a cluster if:

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

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

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

If the failing system is suspected to be part of a shared DASD cluster, all
diagnostic tests can be run except diagnostic tests which test the storage unit
(DASD residing in the storage unit) or the storage adapter attached to the storage
unit.

Notes:

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

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

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

on page 105.

4. If the computer hangs and no error is displayed, go to “Undetermined
problems” on page 117.

5. Power supply problems, see “Power checkout” on page 16 and
“Symptom-to-FRU index” on page 105.

6. Safety information, see “Safety information” on page 123.

7. For intermittent problems, check the error log; see “POST error messages” on

page 12.

© Copyright IBM Corp. 2000 1

1. IS THE SYSTEM PART OF A CLUSTER?
YES. Schedule maintenance with the customer. Shut down all systems related to

the cluster. Run storage test.
NO. Go to step 2.

2. IF THE SYSTEM IS NOT PART OF A CLUSTER:

v Power-off the computer and all external devices.
v Check all cables and power cords.
v Set all display controls to the middle position.
v Power-on all external devices.
v Power-on the computer.
v Record any POST error messages displayed on the screen. If an error is

displayed, look up the first error in the “POST error codes” on page 112.

v Check the diagnostic LED panel system error LED; if on, see “Front panel

and system board LEDs” on page 18.

v Check the System Error Log. If an error was recorded by the system, see

“Symptom-to-FRU index” on page 105.

v Start the Diagnostic Programs. See “Diagnostic programs and error

messages” on page 13.

v Check for the following responses:

a. One beep.
b. Readable instructions or the Main Menu.

3. DID YOU RECEIVE BOTH OF THE CORRECT RESPONSES?

NO. Find the failure symptom in “Symptom-to-FRU index” on page 105.
YES. Run the Diagnostic programs. If necessary, refer to “Diagnostic programs and

error messages” on page 13.

If you receive an error, go to“Symptom-to-FRU index” on page 105.

If the diagnostics completed successfully and you still suspect a problem, see
“Undetermined problems” on page 117.

industry-standard PC133, 3.3 V, 168-pin, 8-byte, registered, synchronous­dynamic-random access memory (SDRAM) dual inline memory modules
(DIMMs).

v System-management capabilities

System-management software is included with the server to manage the
functions of the server locally and remotely. Refer to the documentation that
comes with the system-management software for more information.

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

™

v IBM ServerGuide

CDs

The ServerGuide CDs that are 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 that are 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

Three of the most important considerations in server design are reliability,
availability, and serviceability (RAS). The RAS factors help to ensure the integrity
of the data that is stored on the server, the availability of the server when it is

electrical outlet, the server can start in any of the following ways:

v You can press the power-control button on the front of the server to start the

server.

Notes:

1. You can install a circular disk over the power-control button to prevent
accidental manual power-off. This disk, known as the power-control button
shield, comes with your server.

2. After you plug the power cord of your server into an electrical outlet, wait
approximately 20 seconds before pressing the power-control button. During
this time, the system is initializing; therefore, the power-control button does
not respond.

v If the server is turned on and a power failure occurs, the server will start

automatically when power is restored.

v The Wake on LAN feature will turn on the server at the set time (when a Magic

Packet is received), provided that all of the following conditions are met:

If you cannot locate and correct the problem using the information in this section,
refer to “Symptom-to-FRU index” on page 105 for more information.

Diagnostic tools overview

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

v POST beep codes, error messages, and error logs

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

v Diagnostic programs and error messages

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 Error symptoms

These charts list problem symptoms, along with suggested steps to correct the
problems. See “Diagnosing errors” on page 21 for more information.

v Diagnostic LEDs

The server has light-emitting diodes (LEDs) to help you identify problems with
server components. These LEDs are part of the diagnostics that are built into the

POST

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

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

© Copyright IBM Corp. 2000 11

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

Notes:

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

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

POST beep codes

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

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

information, see “Beep symptoms” on page 105.

POST error messages

POST error messages occur during startup when POST finds a problem with the
hardware or detects a change in the hardware configuration. For a list of POST
errors, see “POST error codes” on page 112.

POST error log

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

To view the contents of the error logs, start the Configuration/Setup Utility
program (see “Starting the Configuration/Setup Utility program” on page 29); then,
select Error Logs from the main menu.

Small computer system interface messages

The following table lists actions to take if you receive a SCSI error message.

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

indicates that the BIOS is not installed.

12 Hardware Maintenance Manual: xSeries 220 Type 8645

You will get these messages only when running the SCSISelect Utility.

Table 1. SCSI messages

SCSI Messages Description

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

v A failing SCSI device (adapter, drive, controller)
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

Action: Verify that:

v The external SCSI devices are turned on. External SCSI 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.

If the above items are correct, run the diagnostic programs to obtain
additional information about the failing device. If the error remains or
recurs, call for service.

Diagnostic programs and error messages

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

Diagnostic error messages indicate that a problem exists; they are not necessarily
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

iii is the three-digit device ID.

that was encountered.

Diagnostics 13

date is the date that the diagnostic test was run and the error recorded.
cc is the check digit that is used to verify the validity of the

text message is the diagnostic message that indicates the reason for the problem.

Text messages

The diagnostic text message format is as follows:

Function Name: Result (test specific string)

where:

Function Name

Result can be one of the following:

information.

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

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

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

3. Remove adapters and disconnect the cables and power connectors to all

4. Reconnect the AC cord and power on the system. If the system powers up

To use this method it is important to know the minimum configuration required
for a system to power up (see page 117).

Recovering BIOS

If the BIOS has become damaged, such as from a power failure during a flash
update, you can recover the BIOS using the flash ROM page-swap jumper (J38)
and a BIOS flash diskette.

required for power on (see ″Minimum operating requirements″ on page 117).

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.

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

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

The flash memory of your server consists of a primary page and a backup page.
The J38 jumper controls which page is used to start the server. If the BIOS in the
primary page is damaged, you can use the backup page to start the server; then,
start the BIOS flash diskette to restore the BIOS to the primary page.

To recover the BIOS, do the following:

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

Identifying problems using status LEDs

The server has diagnostic LEDs to help you identify problems with some server
components. Use the diagnostic LEDs to identify the failing or incorrectly installed
components.

Diagnostics 17

Front panel and system board LEDs

The server does not contain a diagnostic or information panel. The system error
LED is on the front panel inside the server. All of the remaining error LEDs are on
the system board, adjacent to the failing components. See “Diagnostic LEDs” for
information on identifying problems using these LEDs.

The meanings of these LEDs are as follows:

CPU1 Microprocessor number 1 (connector U12) fault
CPU2 Microprocessor number 2 (connector U11) fault
Fan 1 Fan number 1 (connector J10) failure (see note 1)
Fan 2 Fan number 2 (connector J18) failure (see note 1)
MEM1 DIMM number 1 (connector J19) fault
MEM 2 DIMM number 2 (connector J21) fault
MEM 3 DIMM number 3 (connector J23) fault
MEM 4 DIMM number 4 (connector J26) fault
VRM1 Microprocessor VRM number 1 (connector J42) fault (see note 1)
VRM2 Microprocessor VRM number 2 (connector J12) fault (see note 1)
Notes:

1. The fan and VRM LEDs will illuminate only if the optional system
management adapter is installed in the server.

2. The server does not support user-replaceable power supplies or fans.

Diagnostic LEDs

You can use the diagnostic LEDs built into the server to quickly identify the type
of system error that occurred. The server is designed so that LEDs remain
illuminated when the server shuts down, as long as the power supply is operating
properly. This feature helps you to isolate the problem if an error causes the server
to shut down. To correct specific problems, see “Symptom-to-FRU index” on
page 105.

Diagnosing errors

To find solutions to problems that have definite symptoms, see “Error symptoms”

on page 111.

If you cannot find the problem there, go to “Starting the diagnostic programs” on
page 14 to test the server.

If you have just added new software or a new option and the server is not
working, do the following before using the error symptoms table:

v Remove the software or device that you just added.
v Run the diagnostic tests to determine if the server is running correctly.
v Reinstall the new software or new device.

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 LAN activity light on the front of the server. The LAN activity light

illuminates when the Ethernet controller sends or receives data over the Ethernet
network. If the LAN activity light is off, make sure that the hub and network are
operating and that the correct device drivers are loaded.

v Make sure that you are using the correct device drivers, supplied with your

server.

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

protocol.

v Test the Ethernet controller.

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

Suggested Action

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, call for service.
Check the following:

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.

Check the following:
v Make sure that you are using Category 5 cabling when

operating the server at 100 Mbps.

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

sources like fluorescent lights.

Check the following:

v Make sure that the cable is connected to the Ethernet controller.
v Make sure that your 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.

You can use any combination of up to seven characters (A–Z, a–z, and 0–9) for
your power-on password. Keep a record of your password in a secure place. If you
forget the power-on password, you can regain access to the server through one of
the following methods:

v If an administrator password has been set, enter the administrator password at

the power-on prompt. (If necessary, see “Administrator password” on page 34
for details.) Start the Configuration/Setup Utility program and change the
power-on password.

Configuring the server 33

v Start the Configuration/Setup Utility program, and change the power-on

password.

v Change the position of the password-override switch as described in “Setting the

password-override switch”.

v Remove the battery and then reinstall the battery.

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 The cover is in place during normal operations, or is removed for no longer than

30 minutes while the server is operating.

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

properly. Leave about 127 mm (5 in.) of space around the front and rear of the
server.

v Cables for optional adapters are routed according to the instructions provided

with the adapters.

v A failed fan is replaced within 1 hour.

Rotating the stabilizing feet

The feet attached to the bottom cover rotate 90 degrees to provide additional
stability for the server.

56 Hardware Maintenance Manual: xSeries 220 Type 8645

Place the server in an upright position; then, rotate the feet a quarter turn away
from the server. Carefully position the server on its feet.

When you need to access the inside of the server to install options, you might find
it easier to place the server on its side, so that the system board is facing you. If
you do so, rotate the feet in towards the server, so that they do not break off due
to the weight of the server.

Adapter considerations

Before you install adapters, review the following:
v Locate the documentation that comes with the adapter and follow those

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

v You can install full-length adapters in all PCI slots.
v You can install a 32-bit adapter in any of the PCI slots, but you might want to

install it in a 32-bit slot and use the 64-bit slots for 64-bit adapters.

v The server supports 5.0 V and universal PCI adapters; it does not support 3.3 V

adapters.

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 The server has two PCI buses. PCI slots 1 and 2 are on PCI bus A and PCI slots

3, 4, and 5 are on PCI bus B.

Note: PCI bus A is sometimes referred to as bus 0; PCI bus B is sometimes

The system scans PCI slots 1 through 5 to assign system resources; then the
system starts (boots) the PCI devices in the following order: PCI slots 1 and 2,
system board SCSI devices, and then PCI slots 3 through 5.

v If you plan to use the Wake on LAN (WOL) function in the server, you must

install a Wake on LAN-enabled NIC adapter in PCI slot 1, and install the Wake
on LAN cable that comes with the Wake on LAN adapter to connect this adapter
to the system board. You must use a Wake on LAN-enabled adapter as identified
in the xSeries 220 ServerProven list at http://www.ibm.com/pc/compat/. Only
PCI slot 1 supports a Wake on LAN-enabled adapter. For additional information
on the Wake on LAN function, adapters, and cables, refer to the documentation

Bay 7

To remove or install a drive, you must turn off the server first, unless you are
removing or installing a hot-swap hard disk drive. Diskette drives, tape drives,
and CD-ROM drives are removable-media drives. You can install removable-media
drives in bays 1, 2, 3, and 4. You can install SCSI hard disk drives in bays 4, 5, 6,
and 7.

v The server comes with a 3.5-inch, 1.44 MB diskette drive in bay 3, an integrated

drive electronics (IDE) CD-ROM drive in bay 1, and a hard disk drive in bay 7
(in some models).

v The xSeries 220 server supports five 3.5-inch drives; however, the server

supports only one diskette drive.

v The diskette drive uses 1 MB and 2 MB diskettes. For optimum use, format

1 MB diskettes to 720 KB and format 2 MB diskettes to 1.44 MB.

v The xSeries 220 server supports two 5.25-inch drives and four SCSI hard disk

drives. The server does not support IDE hard disk drives. Some models support
hot-swap hard disk drives. Other models support only non-hot-swap hard disk
drives. Refer to the documentation that comes with the server for additional
information.

The server supports four 1-inch (26 mm) slim, 3.5-inch SCSI hard disk drives in
the hard disk drive bays (4, 5, 6, and 7). You can install four non-hot-swap hard
disk drives in the models that have the standard non-hot-swap drive cage. You
can install three hot-swap hard disk drives and one non-hot-swap hard disk
drive in the models that come with the hot-swap drive cage. Both the
non-hot-swap and hot-swap drive cages hold a maximum of three hard disk
drives. The drive cages comprise bays 5, 6, and 7.

v Bay 2 comes without a device installed. This bay is for a 5.25-inch, half-high,

removable-media drive, such as a tape backup drive.

v Bay 4 is for a 3.5-inch, slim, removable-media drive or SCSI hard disk drive.

Installing options 65

Note: The electromagnetic interference (EMI) integrity and cooling of the server

are both protected by having bays 1 through 4 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.

Preinstallation steps (all bays)

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 drive. You
might also need to perform certain preinstallation activities. Some of the steps are
required only during the initial installation of an option.

1. Read “Safety information” on page 123, “Handling electrostatic

discharge-sensitive devices” on page 126, and the documentation that comes
with the drive.

2. Choose the bay in which you want to install the drive.

5. If the drive is a laser product, observe the following safety precaution.

CAUTION:
When laser products (such as CD-ROMs, DVD drives, fiber optic devices, or
transmitters) are installed, note the following:

v Do not remove the covers. Removing the covers of the laser product could result

in exposure to hazardous laser radiation. There are no serviceable parts inside the
device.

v Use of controls or adjustments or performance of procedures other than those

specified herein might result in hazardous radiation exposure.

DANGERSome laser products contain an embedded Class 3A or Class 3B laser diode.

Note the following. Laser radiation when open. Do not stare into the beam, do not
view directly with optical instruments, and avoid direct exposure to the beam.

6. 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.

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

8. Push the drive into the bay.

9. If the drive is an IDE device, plug one connector of the IDE cable into the

back of the drive and the other end of the cable into the IDE connector (J30)
on the system board.

If the drive is a SCSI device, plug one connector of the SCSI cable into the
back of the drive and make sure that the other end of the cable is connected
to the SCSI connector (J41) on the system board.

Note: Ensure that you route the SCSI cable so that it does not block the

airflow to the rear of the drives or over the microprocessors.

10. Connect a power cable to the back of the drive. The connectors are keyed and
can be inserted only one way.

11. If you are installing another drive, do so now. Otherwise, continue with the

next step.

Note: If the server is a hot-swap model, reinstall the VRM in connector J42

after you reinstall the support bracket assembly. (See “System board
options connectors” on page 53 for connector location.)

Installing a hot-swap hard disk drive in bay 5, 6, or 7

If the server is a hot-swap model, it contains hardware that you can use to replace
a failed hard disk drive without turning off the server. Therefore, you have the
advantage of continuing to operate the system while a hard disk drive is removed
or installed. These drives are known as hot-swap drives. If these drives are
connected to an optional controller, such as a ServeRAID controller, that supports
this function, and if one of these drives becomes defective, the ServeRAID
controller can rebuild the data from that drive onto another hot-swap drive. Refer
to the information that comes with the ServeRAID controller for details.

Each hot-swap drive has two indicator lights: the hard disk drive activity light and
the hard disk drive status light. When the green hard disk drive activity light is
flashing, the controller is accessing the hard disk drive. When this occurs, the SCSI
activity light on the front of the server also illuminates. The SCSI activity light is
illustrated and described in “Server controls and indicators” on page 7. If the
amber hard disk drive status light for a drive is lit continuously, that individual
drive is faulty and requires replacement. When the hard disk drive status light
indicates a drive fault, you can replace a hot-swap drive without turning off the
server.

Note: The hard disk drive activity light is also known as the SCSI hard disk drive

activity light.

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

The hot-swap bays connect to a SCSI backplane. This backplane is the printed circuit
board behind the bay. The backplane controls the SCSI IDs for the hot-swap drives.

The following illustration shows the hot-swap-drive backplane component
locations, as viewed from the front of the server.

1. Review “System reliability considerations” on page 56.

2. Read the information in “Preinstallation steps (all bays)” on page 66.

Note: You do not have to turn off the server to install hot-swap hard disk

drives in these bays.

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

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

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

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

Note: If the server has a ServeRAID controller, you might need to reconfigure

the disk arrays after installing hard disk drives. Refer to the information
that comes with the ServeRAID controller.

5. If you have other options to install or remove, do so now.

Installing 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 in-line memory
module (DIMM). The server uses a noninterleaved memory configuration.

The server comes with a dual in-line memory module (DIMM) that is installed on
the system board in DIMM slot 1 (connector J19).

Notes:

1. When installing additional memory modules, install the second memory
module in the connector labeled DIMM3 (J23), the third in DIMM2 (J21), and
the fourth in DIMM4 (J26). (See the following illustration for memory-connector
locations.)

2. The xSeries 220 server supports 128 MB, 256 MB, 512 MB , and 1 GB DIMMs.
These DIMMs can be installed in any memory slot. The server supports a
minimum of 128 MB and a maximum of 4 GB of system memory. See the
ServerProven list at http://www.ibm.com/pc/compat/ for a list of memory
modules for use with the server.

3. Installing or removing DIMMs changes the configuration information in the
server. Therefore, after installing or removing a DIMM, you must save the new
configuration information by using the Configuration/Setup Utility program.
When you restart the server, the system displays a message indicating that the
memory configuration has changed. Start the Configuration/Setup Utility
program and select Save Settings. See “Configuring the server” on page 29 for
more information.

4. The illustrations in this document might differ slightly from your hardware.

Attention: When you handle electrostatic discharge (ESD) sensitive devices, take
precautions to avoid damage from static electricity. For details on handling these
devices, see “Handling electrostatic discharge-sensitive devices” on page 126.

To install a DIMM, do the following:

2. Review the information in “System reliability considerations” on page 56 and
the documentation that comes with the option.

3. Turn off the server and peripheral devices, and disconnect all external cables
and power cords; then, remove the cover (see “Removing the side cover” on
page 57 for details).

4. Select the connector in which to install the DIMM.

5. Touch the static-protective package containing the DIMM to any unpainted

metal surface on the server. Then, remove the DIMM from the package.
Attention: To avoid breaking the retaining clips or damaging the DIMM

connectors, handle the clips gently.

6. Install the DIMM:
a. Open the retaining clips on the connector.
b. Turn the DIMM so that the pins align correctly with the connector.
c. Insert the DIMM into the connector by pressing on one edge of the DIMM

and then on the other edge of the DIMM. Ensure that you press straight
into the connector.

d. Make sure that 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.

7. If you have other options to install or remove, do so now; otherwise, go to
“Installing the cover” on page 79.

Attention: When you restart the server, the system displays a message indicating
that the memory configuration has changed.

v If you installed additional memory, start the Configuration /Setup Utility

program and select Save Settings.

v If you just replaced a failed DIMM, you must start the Configuration /Setup

Utility program, select Advanced Setup, select Memory Settings, highlight the
connector or bank of connectors that you want to enable, then select Enable.

v In some memory configurations, the 3-3-3 beep code might sound during POST

followed by a blank screen. If this occurs, you must restart the server three times
to force the system BIOS to reset the memory connector or bank of connectors
from Disabled to Enabled.

Installing and removing a microprocessor

The server comes with one microprocessor, which is installed on the system board.
If you install an additional microprocessor kit, 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. This enhances performance for database and point-of-sale
applications, integrated manufacturing solutions, and other applications.

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.

Installing options 73

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

3. The server comes with one microprocessor, which is installed in microprocessor
connector U12 (the microprocessor connector that is closer to the power
supply). This is the startup (boot) microprocessor. If you install a
microprocessor in microprocessor connector U11, that one becomes the startup
microprocessor, and the microprocessor that is installed in microprocessor
connector U12 is the application microprocessor. You must also install a VRM
when you install a microprocessor.

4. If you are installing a microprocessor that has a speed of 933 MHz or higher,
you must also install a fan sink and connect the fan-sink power cable to the
system board.

5. The illustrations in this document might differ slightly from your server.

6. If necessary, see “System board options connectors” on page 53 for connector

Attention:

v To avoid damage and ensure proper server operation when you install a new or

additional microprocessor, use microprocessors that have the same cache size
and type and the same clock speed. Microprocessor internal clock frequencies
and external clock frequencies must be identical. See the ServerProven list at
http://www.ibm.com/pc/compat for a list of microprocessors for use with the
server.

v When you handle electrostatic discharge (ESD) sensitive devices, take

precautions to avoid damage from static electricity. For details on handling these
devices, see “Handling electrostatic discharge-sensitive devices” on page 126.

SCSI port

The server has an integrated small computer system interface (SCSI) controller
with an internal connector (J41) on the system board. This controller supports an
Ultra160 SCSI internal channel. This channel 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

If you install a SCSI adapter in the server, you can use its SCSI connector to
connect different types of small computer system interface (SCSI) devices.

Note: If you install a PCI redundant array of independent disks (RAID) adapter,

SCSI cabling requirements

A SCSI cable comes with the server so that you can connect internal SCSI devices
to the SCSI controller on the system board. A SCSI cable comes with the models
that have the hot-swap drive cage option. If you plan to attach external SCSI
devices, you must install an optional SCSI adapter and order additional SCSI
cables.

you can move the SCSI cable from the system-board SCSI connector to an
internal channel connector on the RAID adapter if you want to control the
internal drives from the adapter.

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 that is connected to a SCSI controller or adapter must have a
unique SCSI ID. This ID enables the SCSI controller or adapter 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.

To install external SCSI devices, you must first install an optional SCSI PCI
adapter. Refer to the information that is provided with the device for instructions
to set its SCSI ID.

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

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

Failover for redundant Ethernet

The IBM 10/100 Ethernet Adapter or the IBM 10/100 Etherjet™PCI family of
adapters are optional redundant network interface cards (NIC adapters) 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 that is
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.

High-performance Ethernet modes

The Ethernet controller supports optional modes, such as teaming, priority packets,
and virtual LANs, which provide higher performance and throughput for the
server.

Teaming Mode: The Ethernet controller provides options, called teaming options.
These options increase throughput and fault tolerance when running with
Windows NT 4.0 or NetWare 4.1x or later.

v Adapter fault tolerance (AFT) provides automatic redundancy for the adapter. If

the primary adapter fails, the secondary adapter takes over. Adapter fault
tolerance supports from two to four adapters per team.

v Adaptive load balancing (ALB) enables you to balance the transmission data

flow among two to four adapters. ALB also includes the AFT option. You can
use ALB with any 100BASE-TX switch.

Installing options 89

v Cisco Fast EtherChannel (FEC) creates a team of two to four adapters to

increase transmission and reception thoughput. FEC also includes the AFT
option. You can use FEC only with a switch that has FEC capability.

Teaming requires you to install at least one additional Ethernet adapter. For
additional information about the teaming modes, refer to the documentation that
comes with these additional adapters.

Priority Packet Mode: Priority Packet is a traffic-prioritization utility that you can
use to set up filters to process high-priority traffic before normal traffic. You can
send information from critical nodes or applications with an indicated priority.
Because you set this priority at the host or entry point of the network, the network
devices can base forwarding decisions on priority information that is defined in the
packet.

Priority Packet information is available on the IBM Networking Web site at
http://www.ibm.com/networking/support

Priority Packet prioritizes traffic based on priority filters. These are parameters that
you assign to outgoing (transmit) packets. Using the Priority Filter Wizard, you can
set up predefined or custom priority filters based on a node (MAC) address,
Ethernet type, or by various properties of the protocol and port. Priority Packet
provides two different methods for prioritizing traffic: IEEE 802.1p tagging and
High Priority Queue.

IEEE 802.1p is a new IEEE standard for tagging, or adding additional bytes of
information to packets with different priority levels. Packets are tagged with 4
additional bytes, which increase the packet size and indicate a priority level. When
you send these packets out on the network, the higher priority packets are
transferred first. Priority packet tagging (also known as Traffic Class Expediting)
enables the adapter to work with other elements of the network (such as switches
and routers) to deliver priority packets first. You can assign specific priority levels
from 0 (low) to 7 (high).

You can assign values to packets based on their priority when you use the IEEE

802.1p standard for packet tagging. This method requires a network infrastructure

that supports packet tagging. The routing devices that receive and transfer these
packets on your network must support 802.1p for tagging to be effective.

After you set up the priority filter in Priority Packet, you must start IBMSet and
select 802.1p/802.1Q Tagging on the Advanced tab.

Note: IEEE 802.1p tagging increases the size of the packets that it tags. Some hubs

and switches will not recognize the larger packets and will drop them.
Check your hub or switch documentation to see if they support 802.1p. (You
can configure the switch to strip the tags from the packets and send it on to
the next destination as normal traffic.) If these devices do not support 802.1p
or if you are not sure, use High Priority Queue (HPQ) to prioritize network
traffic.

The requirements for effectively using IEEE 802.1p tagging are:
v The other devices receiving and routing 802.1p tagged packets must support

802.1p.

v The adapters on these devices must support 802.1p. The Ethernet controller in

the xSeries 220 and all IBM 10/100 Ethernet Security Adapters support 802.1p.

90 Hardware Maintenance Manual: xSeries 220 Type 8645

v The adapter cannot be assigned to an adapter team.
v If you are setting up VLANs and packet tagging on the same adapter,

802.1p/802.1Q tagging must be enabled on the IBMSet Advanced tab.

If your network infrastructure devices do not support IEEE 802.1p or you are not
sure, you can still define filters and send packets as high priority. While High
Priority Queue (HPQ) does not provide the precise priority levels of 802.1p
tagging, it does assign traffic as either high or low priority and sends high-priority
packets first. Therefore, if there are multiple applications on a system that is
sending packets, the packets from the application with a filter are sent out first.
HPQ does not change network routing, nor does it add any information to the
packets.

To assign HPQ, you can specify it using Priority Packet when you create or assign
a filter.

To effectively use HPQ tagging, the adapter cannot be assigned to an adapter team.

Virtual LAN Mode: A virtual LAN (VLAN) is a logical grouping of network
devices that are put together as a LAN, regardless of their physical grouping or
collision domains. Using VLANs increases network performance and improves
network security.

VLANs offer you the ability to group users and devices together into logical
workgroups. This can simplify network administration when you are connecting
clients to servers that are geographically dispersed across a building, campus, or
enterprise network.

Normally, VLANs are configured at the switch, and any computer can be a
member of one VLAN per installed network adapter. The Ethernet controller
supersedes this by communicating directly with the switch, enabling multiple
VLANs on a single network adapter (up to 64 VLANs).

To set up VLAN membership, the Ethernet controller must be attached to a switch
that has VLAN capability. You also need to use Windows NT 4.0 or later, or Novell
NetWare 4.1x or later.

Notes:

1. Windows NT versions prior to 4.0 do not support VLANs.

2. VLANs require NT 4.0 with Service Pack 3.0 and the NDIS driver hotfix from

Microsoft.

3. In Windows NT, VLANs cannot be implemented on controllers that have been
configured for teaming options. NetWare can support teaming options and
VLANs on the same adapters.

To join a VLAN from Windows NT 4.0:

1. Create a VLAN on the switch. Use the parameters that you assign there to join
the VLAN from the server. Refer to your switch documentation for more
information.

2. In the Control Panel window, double-click the Network icon.

3. On the Adapters tab, select the adapter that you want to be on the VLAN, and

click Properties.

4. In IBMSet, click Join VLAN. Note that VLANs cannot be assigned to adapters
that are already defined to have an adapter teaming option.

5. Type the VLAN ID and VLAN name. The VLAN ID must match the VLAN ID
of the switch. The ID range is from 1 to 1000. The VLAN name is for
information only and does not need to match the name on the switch.

6. Click Join VLAN.Repeat steps 3 on page 91 through 5 for each VLAN that you
want the server to join. The VLANs that you add are listed on the Adapters
tab.

7. Click Close and restart the computer.
