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 12.
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 91.
4. If the computer hangs and no error is displayed, go to “Undetermined
problems” on page 105.
5. Power supply problems, see “Power checkout” on page 15 and
“Symptom-to-FRU index” on page 91.
6. Safety information, see “Safety information” on page 111.
7. For intermittent problems, check the error log; see “POST error messages” on
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 99.
v Check the diagnostic LED panel system error LED; if on, see “Front panel
and system board LEDs” on page 17.
v Check the System Error Log. If an error was recorded by the system, see
“Symptom-to-FRU index” on page 91.
v Start the Diagnostic Programs. See “Diagnostic programs and error
messages” on page 12.
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 91.
YES. Run the Diagnostic programs. If necessary, refer to “Diagnostic programs and
error messages” on page 12.
If you receive an error, go to“Symptom-to-FRU index” on page 91.

synchronous-dynamic-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 supports the Wake on LAN function and 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
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.
CDs
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
needed; and the ease with which problems can be diagnosed and repaired.
The following is an abbreviated list of the RAS features that e server supports:
v Automatic Server Restart (ASR) after a power failure or system hang
v Automatic BIOS Recovery (ABR) which enables the server to recover if the BIOS
is defective or becomes corrupt

Diagnostics
This section provides basic troubleshooting information to help you resolve some
common problems that might occur with the server.
If you cannot locate and correct the problem using the information in this section,
refer to “Symptom-to-FRU index” on page 91 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 12 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
server. See “Diagnostic LEDs” on page 17 for more information.
POST
When you turn on the server, it performs a series of tests to check the operation of
server components and some of the options installed in the server. This series of
tests is called the power-on self-test or POST.
If POST finishes without detecting any problems, a single beep sounds 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 “POST beep codes” and “POST error messages” on
page 12 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
Beep codes are sounded in a series of beeps. For example, a 1-2-4 beep code
sounds like one beep, a pause, two consecutive beeps, another pause, and four
more consecutive beeps.
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 91.
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 99.
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.
You will get these messages only when running the SCSISelect Utility.
Table 1. SCSI messages
SCSI MessagesDescription
AllOne 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.
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.
12Hardware Maintenance Manual: xSeries 220 Type 8646
Page 21
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:
fffis the three-digit function code that indicates the function being tested
when the error occurred. For example, function code 089 is for the
microprocessor.
tttis the three-digit failure code that indicates the exact test failure that was
encountered.
iiiis the three-digit device ID.
dateis the date that the diagnostic test was run and the error recorded.
ccis 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.
Text messages
The diagnostic text message format is as follows:
Function Name: Result (test specific string)
where:
Function Name
Resultcan be one of the following:
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
it is complete.
Not Applicable
This result occurs when you specify a diagnostic test for a
device that is not present.
Diagnostics13
Page 22
Aborted
This result occurs when the test could not proceed because
of the system configuration.
Warning
This result occurs when a possible problem is reported
during the diagnostic test, such as when a device that is to
be tested is not installed.
Test Specific String
This is additional information that you can use to analyze the
problem.
Starting the diagnostic programs
You can press F1 while running the diagnostic programs to obtain Help
information. You also can press F1 from within a help screen to obtain online
documentation from which you can select different categories. To exit Help and
return to where you left off, press Esc.
To start the diagnostic programs:
1. Turn on the server and watch the screen.
2. When the message F2 for Diagnostics appears, press F2.
3. Type in the appropriate password; then, press Enter.
4. Select either Extended or Basic from the top of the screen.
5. When the Diagnostic Programs screen appears, select the test you want to run
from the list that appears; then, follow the instructions on the screen.
Notes:
a. If the server stops during testing and you cannot continue, restart the server
and try running the diagnostic programs again.
b. The keyboard and mouse (pointing device) tests assume that a keyboard
and mouse are attached to the server.
c. If you run the diagnostic programs with no mouse attached to the server,
you will not be able to navigate between test categories using the Next Cat
and Prev Cat buttons. All other functions provided by mouse-selectable
buttons are also available using the function keys.
d. You can test the USB by using the regular keyboard test. The regular mouse
test can test a USB mouse. Also, you can run the USB interface test only if
there are no USB devices attached.
e. You can view server configuration information (such as system
configuration, memory contents, interrupt request (IRQ) use, direct memory
access (DMA) use, device drivers, and so on) by selecting Hardware Info
from the top of the screen.
When the tests have completed, you can view the Test Log by selecting Utility
from the top of the screen.
If the hardware checks out OK but the problem persists during normal server
operations, a software error might be the cause. If you suspect a software problem,
refer to the information that comes with the software package.

For descriptions of the error messages that might appear when you run the
diagnostic programs, see “Diagnostic error codes” on page 94. If diagnostic error
messages appear that are not listed in those tables, make sure that the server has
the latest levels of BIOS, ServeRAID, and diagnostics microcode installed.
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 106).
Recovering BIOS
The flash memory of the server consists of a primary BIOS page and a backup
BIOS page. The server has an Automatic BIOS Recovery (ABR) feature which
allows recovery when the BIOS is damaged (e.g. BIOS is damaged when the server
loses power during the flash update). When the ABR feature finds the primary
BIOS damaged, circuitry switches to the backup BIOS and restarts the system. If
the primary BIOS has become damaged, ABR will proceed and boot the backup
BIOS and the system will function normally. However, the primary BIOS should be
updated using a BIOS flash diskette as soon as possible. The flash diskette always

internal and external devices until system is at minimum configuration
required for power on (see ″Minimum operating requirements″ on page 106).
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.
Diagnostics15
Page 24
updates the primary BIOS. The backup BIOS can be updated by moving the
primary BIOS to the backup BIOS page during the diskette flash update process.
The ABR feature can be disabled with the jumper J20; this action is not normally
required.
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.
To recover the BIOS, do the following:
1. Shutdown the server
2. Insert the BIOS flash diskette into the diskette drive.
3. Restart the server. The system begins the power-on self-test (POST).
4. Follow the on-screen instructions to update the BIOS.
5. Restart the server when the flash update is complete.
Another jumper, J38, can be used to force the system to boot from the backup
POST/BIOS (manually boot to backup BIOS). Normally this action is not required,
but if the primary BIOS is damaged, and ABR is not functioning properly, the
jumper can be moved for troubleshooting purposes. If jumper J38 is in the backup
page position, the ABR feature is disabled, regardless of the jumper J20 position,
and the system will boot from the backup BIOS page.
To manually boot to backup BIOS and recover primary BIOS:
1. Turn off the server and peripheral devices and disconnect power cords and all
external cables; then, remove the cover.
2. Locate jumper J38 on the system board.

Identifying problems using status LEDs
The server has LEDs to help you identify problems with some server components.
These LEDs are part of the diagnostics that are built into the server. Use the
illuminated LEDs to identify the failing or incorrectly installed components.
Front panel and system board LEDs
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:
CPU 1Microprocessor number 1 (connector U12) fault
CPU 2Microprocessor number 2 (connector U11) fault
Fan 1Fan number 1 (connector J10) failure (see note 1)
Fan 2Fan number 2 (connector J18) failure (see note 1)
Fan 3Fan number 3 (connector J3) failure (see note 1)
Fan 4Fan number 4 (connector J2) failure (see note 1)
DIMM 1DIMM number 1 (connector DIMM 1) fault
DIMM 2DIMM number 2 (connector DIMM 2) fault
DIMM 3DIMM number 3 (connector DIMM 3) fault
DIMM 4DIMM number 4 (connector DIMM 4) fault
VRM 1Microprocessor VRM number 1 (connector J42) fault (see note 1)
VRM 2Microprocessor VRM number 2 (connector J12) fault (see note 1)
Notes:
1. The fan and VRM LEDs will illuminate only if the IBM Remote Supervisor
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 91.

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.
Diagnostics21
Page 30
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 rear 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.
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.

Flash ROM page jumper (J38) determines whether primary or secondary (backup)
POST/BIOS code is used by the system to start up. The default setting for J38 is a
jumper between pins 2 and 3 (primary POST/BIOS). For backup POST/BIOS,
place a jumper between pins 1 and 2 of J38. Normally this action is not required,
but if the primary BIOS is damaged, and ABR is not functioning properly, the
jumper can be moved for troubleshooting purposes. Changing the jumper position
after system power-on is not permitted; it may cause unpredictable problems.
Note: The BIOS Flash Update Utility always updates the primary BIOS.
Automatic BIOS Recovery (ABR) Jumper
The default setting for J20 is no jumper. If it is necessary to disable ABR during
trouble shooting, install a jumper on J20.
Automatic Server Restart (ASR)
To enable Automatic Server Restart, a special device driver must be loaded. This
device driver enables the ASR watch-dog timer and then periodically resets it
(within 5 minutes). If not reset, the ASR watch-dog timer will expire and boot the
system. The watch-dog timer will re-arm itself after being reset. To disable the ASR
hardware, a jumper must be installed between pins 1 and 2 of J14. THe default is
no jumper installed (ASR enabled).

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
referred to as bus 1.
The system scans PCI slots 1 through 5 to assign system resources; then the
48Hardware Maintenance Manual: xSeries 220 Type 8646
Page 57
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 IBM Remote Supervisor Adapter in the server, you must
install the IBM Remote Supervisor Adapter in PCI slot 2. Only PCI slot 2
supports the IBM Remote Supervisor Adapter. For additional information on the
IBM Remote Supervisor Adapter, refer to the documentation that comes with the

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

minutes without either a drive or a filler panel installed in each bay.
To install a hot-swap hard disk drive in bay 5, 6, or 7, do the following:
1. Review “System reliability considerations” on page 44.
2. Read the information in “Preinstallation steps (all bays)” on page 53.
Note: You do not have to turn off the server to install hot-swap hard disk
drives in these bays.
Installing options57
Page 66
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 non-interleaved memory configuration.
The server comes with a dual in-line memory module (DIMM) that is installed on
the system board in DIMM slot 1 (labeled DIMM 1).
Notes:
1. When installing additional memory modules, install the second memory
module in the connector labeled DIMM 2, the third in DIMM 3, and the fourth
in DIMM 4. (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 “Configuration” on page 29 for more
information.

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.
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 furthest from 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. When you are installing a microprocessor, 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.

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 American National Standards Institute (ANSI) SCSI
standards. Adhering to these standards will help ensure that your 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. SCSI IDs for hot-swap drives are
automatically set by the hot-swap backplane. For hot-swap drives, bay 7 has ID 0,
bay 6 has ID 1, bay 5 has ID 2. For non-hot-swap drives, refer to the information
that comes with the drives for instructions to set their SCSI IDs.
External SCSI devices
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.

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.
74Hardware Maintenance Manual: xSeries 220 Type 8646
Page 83
v Cisco Fast EtherChannel (FEC) creates a team of two to four adapters to
increase transmission and reception throughput. 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.
Installing options75
Page 84
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.
76Hardware Maintenance Manual: xSeries 220 Type 8646
Page 85
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 76 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.
