• Impressive performance using an innovative approach to SMP
Your server supports up to two Pentium III microprocessors. Your server comes
with one microprocessor installed; you can install an additional microprocessor
to enhance performance and provide SMP capability.
• Large data-storage and hot-swap capabilities
All models of the server support up to six hot-swap hard disk drives. This hot-
swap feature enables you to remove and replace hard disk drives without
turning off the server.
• Redundant power capabilities
The standard 250-watt power supply in your server can handle a load of up to
250 watts. By replacing the power backplane with the power backplane option,
you can install a second, optional power supply. This provides a full 500 watts
of power. If the average load on your server is less than 250 watts and a problem
occurs with one of the power supplies, the other power supply can handle the
load (redundant power). If the average load on your server is greater than 250
watts, and you have installed a second power supply, you can install a third,
optional power supply to provide redundancy.
The NON light emitting diode (LED) on the system board is lit when the power
load is 250 watts or greater with two power supplies, or when the power load is
500 watts or greater with three power supplies.
• Large system memory
The memory bus in your server supports up to 4gigabytes (GB) of system
memory. The memory controller provides error correcting code (ECC) support
for up to four industry standard PC133, 3.3 V, 168-pin, 8-byte, registered,
synchronous-dynamic-random access memory (SDRAM) dual inline memory
modules (DIMMs).
4 IBM® xSeries 150 : User’s Reference
• System-management capabilities
Y our server comes with a Netfinity Advanced System Management Processor on
the system board. This processor enables you to manage the functions of the
server locally and remotely. The Netfinity Advanced System Management
Processor also provides system monitoring, event recording, and dial-out alert
capability.
Note: The Netfinity Advanced System Managem e nt Processor is sometimes
referred to as the service processor.
• Integrated network environment support
Your server comes with an Ethernet controller on the system board. This
Ethernet controller has an interface for connecting to 10-Mbps or 100-Mbps
networks. The server automatically selects between 10BASE-T and 100BASE-TX.
The controller provides full-duplex (FDX) capability , which allows simultaneous
transmission and reception of data on the Ethernet local area network (LAN).
• Redundant network-interface card
The addition of an optional, redundant network interface card (NIC) provides a
failover capability to a redundant Ethernet connection. If a problem occurs with
the primary Ethernet connection, all Ethernet traf fic associated with this primary
connection is automatically switched to the redundant NIC. This switching
occurs without data loss and without user intervention.
• Optional digital linear tape drive
The addition of an optional digital linear tape drive (DLT) allows quick backup
of large amounts of data.
Reliability, availability, and serviceability features
Three of the most important features in server design are reliability, availability, and
serviceability (RAS). These factors help to ensure the integrity of the data stored on
your server; that your server is available when you want to use it; and that should a
failure occur, you can easily diagnose and repair the failu re with mi nimal
inconvenience.
The following is an abbreviated list of the RAS features that your server supports.
• Menu-driven setup, system configuration, RAID configuration, and diagnostic
programs
• Power-on self-test (POST)
• Integrated Netfinity Advanced System Management Processor
• Predictive failure alerts
• Remote system problem-analysis support
• Power and temperature monitoring
• Hot-swap drive bays
• Error codes and messages
• System error logging
• Upgradable BIOS, diagnostics, and Netfinity Advanced System Management
Processor code
• Automatic restart after a power failure

Chapter 2. Arranging your workspace
To get the most from your server, arrange both the equipment you use and your work
area to suit your needs and the kind of work you do. Your comfort is of foremost
importance, but light sources, air circulation, and the location of electrical outlets also
can affect the way you arrange your workspace.
Comfort
Although no single working position is ideal for everyone, here are a few guidelines
to help you find a position tha t suits you best.
Sitting in the same position for a long time can cause fatigue. A good chair can make a
big difference. The backrest and seat should adjust independently and provide good
support. The seat should have a curved front to relieve pressure on the thighs. Adjust
the seat so that your thighs are parallel to the floor and your feet are either flat on the
floor or on a footrest.
When using the keyboard, keep your for earms parallel to the floor and your wrists in
a neutral, comfortable position. Try to keep a light touch on the keyboard and your
hands and fingers relaxed. You can change the angle of the keyboard for maximum
comfort by adjusting the position of the keyboard feet.
Adjust the monitor so the top of the screen is at, or slightly below, eye level. Place the
monitor at a comfortable viewing distance, usually 51 to 61 cm (20 to 24 in.), and
position it so you can view it without having to twist your body. Also position other
equipment you use regularly, such as the telephone or a mouse, within easy reach.
Glare and lighting
Position the monitor to minimize glare and reflections from overhead lights,
windows, and other light sources. Even reflected light from shiny surfaces can cause
annoying reflections on your monitor screen. Place the monitor at right angles to
windows and other light sources, when possi ble. Red uce overhead lighting, if
necessary, by turning off lights or using lower wattage bulbs. If you in stall the
monitor near a window, use curt ains or blinds to block the sunlight. You might have
to adjust the Brightness and Contrast controls on the mon itor as the room lighting
changes throughout the day.
Where it is impossible to avoid reflections or to adjust the lighting, an antiglare filter
placed over the screen might be helpful. However, these filters might affect the clarity
of the image on the screen; try them only after you have tried all other methods of
reducing glare.
Dust buildup compounds problems that are associated with glare. Remember to clean
your monitor screen periodically using a soft cloth that is moistened with a
nonabrasive liquid glass cleaner.
Air circulation
Your server and monitor produce heat. Your server has one or more fans that pull in
fresh air and force out hot air . The monitor lets hot air escape through vents. Blocking
the air vents can cause overheating, which might result in a malfunction or dama ge.
10 IBM® xSeries 150 : Use r’s Reference
Place the server and monitor so that nothing blocks the air vents; usually, 15 cm (6
inches) of air space is sufficient. Also, make sure that the vented air is not blowing on
someone else.
Electrical outlets and cable lengths
The location of electrical outlets and the length of power cords and cables that connect
to the monitor, printer, and other devices might determine the final placement of your
server.
When arranging your workspace:
• Avoid the use of extension cords. When possible, plug the server power cords
directly into electrical outlets.
• Keep power cords and cables neatly routed away from walkways and other
areas where they might get kicked accidentally.
For more information about power cords, refer to the power cord information in this
on-line publication.

• 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 6 4-b it slots for 64-bit adapters.
• Your server supports 5.0V and universal PCI ad apters; it does not support 3.3V
adapters.
• You might require additional power supplies if adapters are added that have
electrical current requirements that exceed the installed power supply
capabilities.
• Your 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.
• 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 often referred to as bus 0; PCI bus B is often referred to as
bus 1.

• Diskette (already installed)
• Hard disk
• CD-ROM (already installed)
• Tape, including DLT
Internal drive bays
Interna l d riv es are insta lled in bays. The bays of the xSeries 150 are in the front of the
server, as shown in the following illustrations.
Attention: If you are going to install additional drives in the non-hot-swap bays, you
must install the power supply backplane op tion and additional power supplies.

Hot-swap drives
Your server contains hardware that lets you continue to operate your system while a
hard disk drive is removed or installed. These drives are known as hot-swappable
drives. They are also referred to as hot-swap drives.
Each hot-swap drive that you plan to install must have a hot-swap-drive tray
attached. The drive must have a single connector attachment (SCA) connector. Hotswap-drive trays come with the hot-swap drives.
• Your server supports six slim (1-inch) or three half-high (1.6-inch), 3.5-inch hot-
swap hard disk drives in the hot-swap bays.
• 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.
Non-hot-swap drives
Diskette drives, tape drives, and CD-ROM drives are non-hot-swap drives. To remove
or install a non-hot swap drive, you must turn off the server first. Non-hot-swap
drives are installed in bays A, B, C, and D only.
• Your server comes with a preinstalled 3.5-inch, 1.44 MB diskette drive in bay D
and a preinstalled IDE CD-ROM drive in bay C.
• The xSeries 150 server supports only one diskette drive.
• The diskette dri ve uses 1 MB and 2 MB diskettes. For optimum use, format 1 MB
diskettes to 720 KB and format 2 MB diskettes to 1.4 4 MB.
• Bays A and B come without a device installed. These bays are for 5.25-inch, half-
high, removable-media drives, such as tape backup drives. You can combine
bays A and B into a single full-high bay.
• If you are installing a device with a 50-pin connector in one of the empty non-
hot-swap bays (bays A–B), you need a 68-pin to 50-pin converter. To order the
converter, contact your IBM reseller or IBM marketing representative.

Note: The server’s electromagnetic interference (EMI) integrity and cooling are both
protected by having bays A and B 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 your server, verify that you have all the cables and any
other equipment specified in the documentation that comes with the internal drive.
Y ou 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” on page iii, “Handling static sensitive devices” on page 20, and the
documentation that comes with your drive.
2. Choose the bay in which you want to install the drive.
3. Check the instructions that come with the drive to see if you need to set any
switches or jumpers on the drive.
4. To install t he d rive , go to “Ins t al li n g a h o t- sw ap drive” or to “Installing a non-hotswap drive” on page 38, as appropriate.
Installing a hot-swap drive
Note: The illustrations in this document might differ slightly from your hardware.
To install a drive in a hot-swap drive bay:
Attention:
• To maintain proper system cooling, do not operate the server for more than two
minutes without either a drive or a filler panel installed for each bay.
• When you handle Electrostatic Discharge-Sensitive devices (ESD), take
precautions to avoid damage from static electricity. For details on handling these
devices, refer to the following Web site and use a search term of ESD:
http://www.ibm.com/
1. 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 a nd pulling it away
from the server.
Note: If you are installing a half-high hard disk drive, you will need to remove
two adjacent filler panels. The two filler panels should be from either the
top pair of bays, the middle pair of bays, or the bottom pair of bays.

2. Install the hard disk drive in the hot-swap bay:
a. Ensure the tray handle is open (that is, perpendicular to the drive).
b. Align the rails on the drive assembly with the gui de rails in the drive bay.
c. Gently push the drive assembly into the ba y until the drive connects to the
backplane.
d. Push the tray handle toward the closed position until it locks the drive in
place.
3. If you installed a half-high hard disk drive, install a slim filler in the gap above the
drive:
a. Locate the slim filler that is desig ned for use with these half-high drives. It is
stored on the empty tray of the filler panel that you removed earlier in this
procedure.
b. Pull the slim filler off the filler panel.
c. Gently push the slim filler into place in the gap above the drive.
4. Check the hard disk drive status indicators to verify that the hard disk drives are
operating properly (see “Server controls and indicators” on page 6 for the location
of the status indicators).
• When the amber light is on continuously, the drive has failed.
• If you have a RAID adapter installed:
— When the green light flashes slowly (one flash per second), the drive is
being rebuilt.
— When the green light flashes rapidly (three flashes per second), the
controller is identifying the drive.
Note: If your server has a RAID adapter installed, refer to the information provided
with the RAID adapter for information about adding a drive.
Replacing a drive in a hot-swap bay
You do not have to turn off the server to remove or install the hot-swap drives.
Attention:
1. Before you remove a hot-swap hard disk drive that is not defective, back up all
important data.
2. To avoid damage to a hard disk drive, DO NOT remove the drive from the hotswap bay until it has had time to spin down (approximately 30 seconds). Handle
the drive carefully.
3. Before you replace a hot-swap drive, make sure it is defective. If you partially or
completely remove a good drive instead of a defective one, your server might lose
valuable data.
This situation is especially relevant if your server has a RAID adapter installed
and you assigned RAID level 1 or 5 to the logical drives in your disk array. The
RAID adapter can rebuild the data that you need, provided that certain
conditions are met. Refer to the information provided with the RAID adapter for
further details.
Refer to the following illustration of the tow er mode l while you perform the steps in
this procedure.

Installing memory modules
Adding memory to your server is an easy way to make programs run faster. You can
increase the amount of memory in your server by insta lling options called memory-
module kits. Each kit contains one industry-standard, dual-inline memory module
(DIMM). Your server uses a noninterleaved memory configuration.
Your server comes with a dual inline memory module (DIMM) installed on the
system board in connector J23.
Notes:
1. Install additional DIMMs in the order specified in the documentation that comes
with your option. (See the following illustration for memory connector locations.)
2. Your xSeries 150 server supports 128MB, 256MB, 512MB, and 1GB DIMMs. Your
server supports a minimum of 128MB and a maximum of 4GB of system memory.
See the ServerProven list at http://www.ibm.com/pc/netfinity for a list of
memory modules for use with your 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. Sta rt the Configuration/Setup Utility
program and select Save Settings.
4. The illustrations in this document might differ slightly from your hardware.
To install a DIMM:
Attention: When you handle Electrostatic Discharge-Sensitive devices (ESD), take

installed. In this case, open the retaining clips and remove the DIMM; then,
reinsert the DIM M.
6. If you have other options to install or remove, do so now; otherwise, go to
“Installing the cover ” on page 49.
Installing a microprocessor
Your server comes with one microprocessor installed on the system board. If you
install an additional microprocessor, your 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 your
server is available through the World Wide Web and the IBM Bulletin Board
System (BBS). Refer to “Service support” on page 11 6 for the appropriate World
Wide Web addresses and bulletin-board telephone numbers.
2. Obtain an SMP-capable opera ting system (optional). For a list of supported
operating systems, see http://www.ibm.com/pc/us/compat/ on the World
Wide Web.
3. Your server comes with one microprocessor installed in the microprocessor
connector (U3) that is closest to the power supply. This is the startup (boot)
microprocessor. A microprocessor installed in connector U17 is microprocessor 2.
If more than one microprocessor is installed, the microprocessor installed in
microprocessor connector U17 is the startup processor and the microprocessor
installed in U3 is the application processor.
Attention: To avoid damage and ensure proper server operation when you install a
new or an additional microprocessor, use microprocessors that have the same cache
size and type, and the same clock speed. Microprocessor internal clock frequencies
and external clock frequencies must be identical. See the ServerProven list at
http://www.ibm.com/pc/netfinity for a list of microprocessors for use with your
server.
Note: The illustrations in this document might differ slightly from your hardware.

SCSI ports
Your server has an integrated dual-channel Ultra3 small computer system interface
(SCSI) controller. This controller supports two independent Ultra 160/m SCSI
channels, both internal. Each of these channels supports up to 15 SCSI devices. In
addition, this controller uses:
• Double-transition clocking to achieve high transfer rates
• Domain name validation to negotiate compatible data transfer speeds with each
device
• Cyclic-redundancy checking (CRC), instead of the usual parity checking, to
significantly improve data reliability
• An active terminator on the system board for SCSI bus termination
A SCSI cable connects the SCSI channel A connector to the hot-swap drive backplane.
If you obtain an additional SCSI cable, the SCSI channel B connector is available for
connecting non-hot-swap SCSI drives in the 5.25-in. bays.
If you install a SCSI adapter in your server, you can use its SCSI connector to connect
different types of small computer system interface (SCSI) devices.
Note: If you install a PCI RAID adapter to configure and manage the internal hot-
swap drives, you must move the SCSI cable from the system-board SCSI
connector to an internal channel connector on the RAID adapter.
SCSI cabling requirements
If you plan to attach external SCSI devices, you must order additional SCSI cables. To
select and order the correct cables for use with external devices, contact your IBM
reseller or IBM marketing representative.
For information about the maximum length of SCSI cable between the terminated
ends of the cable, refer to the ANSI SCSI standards. Adhering to these standards will
help ensure that your server operates properly.
Setting SCSI IDs
Each SCSI device connected to a SCSI controller must have a unique SCSI ID. This ID
enables the SCSI controller to identify the device and ensure that different devices on
the same SCSI channel do not attempt to transfer data simultaneously. SCSI devices
that are connected to different SCSI channels can have duplicate SCSI IDs.
The hot-swap-drive backplane controls the SCSI IDs for the internal hot-swap drive
bays. However, when you attach SCSI devices to the external SCSI connector, you
must set a unique ID for the device. Refer to the information that is provided with the
device for instructions to set its SCSI ID.

Chapter 3. Installing Options 61
Ethernet port
Your 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 simultaneou s 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 your server.
Notes:
1. The 100BASE-TX Fast Ethernet standard requires that the cabling in the network
be Category 5 or higher.
2. If you plan to use the IBM Advanced Appliance Conf iguration Utility to
configure and manage your appliance, be sure to connect the built-in Ethernet
connector to the same physical network as your sys tems management console.
Configuring the Ethernet controller
When you connect your server to the network, the Ethernet controller automatically
detects the data-transfer rate (10Mbps or 100Mbp s) on the network and then sets the
controller to operate at the appr opriate rate. That is, the Ethernet co ntr oller 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. Yo u do not n eed to set any
jumpers or configure the controller for your operating system before you use the
Ethernet controller. However, you must install a device driver to enable your
operating system to address the Ethernet controller. The device drivers are provided
on the ServerGuide CDs.
Failover for redundant Ethernet
The IBM Netfinity 10/100 Fault Tolerant Adapter is an optional redundant network
interface card (NIC adapter) that you can install in your 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 failur e, all
Ethernet traffic associated with it is switched to the redundant (secondary) controller.
This switching occurs without any user intervention. When the primary link is
restored to an operational state, the Ethernet traffic switches back to the primary
Ethernet controller. The switch back to the primary Ethernet controller can be
automatic or manually controlled, d e pend ing on the setup and operating system.
Note that only one controller in the redundant pair is active at any given time. For
example, if the primary Ethernet controller is active, then the secondary Ethernet
controller cannot be used for any other network operation .
Note: Your operating system determines the maximum number of IBM Netfin ity
10/100 Fault Tolerant Adapters that you can install in your server. See the
documentation that comes with the adapter for more information .

2. Use the ServerGuide CDs to install the AMD PCNet Ethernet Family adapter
device driver.
3. Do not select the Grouping box at this point; yo u must first restart the machine.
4. From the Windows NT Server desktop, select Control Panel, then select the
Network icon, then select the Adapters tab.
5. Highlight one of the adapters that will be in the redundant pair and then click the
Properties... button.
6. Check the Grouping box. This will show the possible combinations for redundant
pairs.
7. Select the adapter pair you want and then select OK. Note that the integrated
Ethernet controller is located at PCI bus A, slot 2.
8. Select Close to exit from the Network setup.
When you restart the server, the failover function will be in effect.
If a failover occurs, a message is written to the NT Event Viewer log.
IntraNetWare:
1. Add the redundant NIC adapter according to the instructions that are provided
with the adapter.
2. Load the device driver by using the following command:
LOAD d:\path\PCNTNW.LAN PRIMARY=x SECONDARY=y
where d and path are the drive and path where the driver is located, and x and y
are the PCI slot numbers where the redundant pair is located.
The slot number associated with the integrated Ethernet controller can vary
depending on the configuration of the server. To determine the slot number, load
the driver with no parameters. The driver will display the available slot numbers.
The slot number that is greater that 10000 will be the slot number of integrated
Ethernet controller. When the slot number of the integrated Ethernet controller is
determined, reload the driver with the appropriate parameters.
3. When the driver is loaded, bind it to a protocol stack.
The failover function is now enabled. If a failover occurs:
• The operating system console generates a message.
• The custom counters for the device driver contain variables that define the state
of the failover function and the location of the redundant pair. You can use the
NetWare Monitor to view the custom counters.

the rear of your server to communicate with the integrated Netfinity Advanced
System Management Processor.
If you install the Advanced System Management Interconnect cable option, it
provides two additional ports, which are used for the RS-485 function. These two
ports use a dual RJ-45 connector. The RS-485 function enables you to connect the
Advanced System Management Processors of several rack-mounted servers so that
they can communicate with each other in half-duplex mode.
Note: When using the RS-485 function, at least one of the servers in the group that is

POST
When you turn on the server, it performs a series of tests to check the operation of
server components and some of the options installed in the server. This series of tests
is called the power-on self-test or POST.
If POST finishes without detecting any problems, a single beep sounds, the first screen
of your operating system or application program appears, and the System POST
Complete (OK) light is illuminated on the operator information panel.
If POST detects a problem, more than one beep sounds and an err or m essage appea rs
on your screen. See “POST beep code descriptions” and “POST error messages” on
page 73 for more information.
Notes:
1. If you have a power-on passwo rd or admin istrator 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 code descriptions
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.
The possible types of beep codes that your server might emit include the following:
No beeps If no beep occurs after your server completes POST (that is, after the System
POST Complete (OK) light on the operator information panel is illuminated),
call for service.
Continuous beep
Your startup (boot) microprocessor has failed, or your system board or
speaker subsystem might contain a failing component. If the system
continues through POST with no errors, call for service. If no video appears,
the startup processor has failed; replace the startup processor.
One short beep
One beep indicates that your server successfully completed POST. POST
detected no configuration or functional errors. One beep also occurs after
your server completes POST if you enter an incorrect power-on password.
Two short beeps
POST encountered an error. The Configuration/Setup Utility program will
display additional information; follow the instructions that appear on the
screen. See “POST error messages” on page 73 for descriptions of the text
messages that might appear.
Three short beeps
A system memory error has occurred. This combination occurs only if the
video Basic Input/Output System (BIOS) cannot display the error message.
Replace the failing memory module.
Repeating short beeps
The system board might contain a failing component, your keyboard might
be defective, or a key on the keyboard might be stuck. Ensure that:
Chapter 4. Solving Problems 71
1. Nothing is resting on the keyb oard and pressing a key.
2. No key is stuck.
3. The keyboard cable is connected correctly to the keyboard and to the
correct connector on the server.
Running the diagnostic tests can isolate the server component that failed, but
you must have your system serviced. If the error message remains, call for
service.
Note: If you just connected a new mouse or other pointing device, turn off
the server and disconnect that device. Wa it at least 5 seconds; then,
turn on the server. If the error message goes away, replace the device.
One long and one short beep
POST encountered an error on a video adapter. If you are using the integrated
video controller, call for service. If you are using an optional video adapter,
replace the failing video adapter.
One long and two short beeps
A video I/O adapter ROM is not readable, or the video subsyste m is
defective. If you hear this beep combination twice, both the system board and
an optional video adapter have failed the test. This beep combination might
also indicate that the system board contains a failing component.
One long and three short beeps
The system-board video subsystem has not detected a monitor conn ection to
the server. Ensure that the monitor is connected to the server. If the problem
persists, replace the monitor.
Two long and two short beeps
POST does not support the optional video adapter. This beep combination
occurs when you install a video adapter that is incompatible with your server.
Replace the optional video adapter with one that the server supports or use
the integrated video controller.

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 your server.
Diagnostic error messages indicate that a problem exists; they are not intended to be
used to identify a failing part. Troubleshooting and servicing of complex problems
that are indicated by error messages should be performed by trained service
personnel.
Sometimes the first error to occur causes additional errors. In this case, the server
displays more than one error message. Always follow the suggested action
instructions for the first error message that appears.
The following sections contain the error codes that might appea r in the detailed test
log and summary log when runnin g 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 fu nction being tested when
the error occurred. For example, function code 089 is for the microprocessor.
ttt is the three-digit failure code that indicates the exact test failure that was
encountered. (These codes ar e fo r trained service personnel and ar e des cribed
in the Hardware Maintenance Manual.)
Table 13. SCSI messages
SCSI Messages Description
All One or more of the following might be causing the problem.
• A failing SCSI device (adapter, drive, controller)

• The external SCSI devices are turned on. Externa l SCSI devices must
be turned on before the server.
• The cables for all external SCSI devices are connected correctly.
• The last device in each SCSI chain is terminated properly.
• The SCSI devices are configured correctly.
If the above items are correct, run the diagnostic programs to obtain

iii is the three-digit device ID. (These codes are for trained service personnel and
are described in the Hardware Maintenance Manual.)
date is the date that the diag nostic test was run and the error recorded.
cc is the check digit that is used to verify the validity of the information.
text message
is the diagnostic message that indicates the reason for the problem.
Text messages
The diagnostic text message format is as follows:
Function Name: Result (test specific string)
where:
Function Name
is the name of the function being tested when the error occurred. This
corresponds to the function code (fff) given in the previous list.
Result can be one of the following:
Passed This result occurs when the diagnostic test completes without any
errors.
Failed This result occurs when the diagnostic test discovers an error.
User Aborted
This result occurs when you stop the diagnostic test before it is
complete.
Not Applicable
This result occurs when you specify a diagnostic test for a device that
is not present.
Aborted This result occurs when the test could not proceed because of the
system configuration.
Warning This result occurs when a possible problem is reported during the
diagnostic test, such as when a device that is to be tested is not
installed.
Test Specific String
This is additional information that you can use to analyze the problem.
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 progra ms :
1. Turn on the server and watch the screen.
Note: To run the diagnostic programs, you must start the server with the
highest level password that is set. That is, if an administrator password is
set, you must enter the administrator password, not the power-on
password, to run the diagnostic programs.

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. If the problem persists, call
for service.
b. The keyboard and mouse (pointing de vice) tests assume that a keyboard and
mouse are attached to the server.
c. If you run the diagnostic programs with no mouse attached to your server,
you will not be able to navigate between test categories using the Next Cat
and Prev Cat buttons. All othe r functions provided by mouse-selectable
buttons are also available using the function keys.
d. You can test the USB keyboard by using the regular keyboard test. The
regular mouse test can test a USB mouse. Also, you can run the USB hub test
only if there are no USB devices attached.
e. Y ou 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.
Viewing the test log
The test log will not contain any info rmation until after the diagnostic program has
run.
Note: If you already are running the diagnostic programs, begin with step 3.
To view the test log:
1. Turn on the server and watch the screen.
If the server is on, shut down your operating system and restart the server.
2. When the message F2 for Diagnostics appears, press F2.
If a power-on password or administrator password is set, the server prompts you
for it. Type in the appropriate password; then, press Enter.
3. When the Diagnostic Programs screen appears, select Utility from the top of the
screen.
4. Select View Test Log from the list that appears; then, follow the instructions on
the screen.
The system maintains the test-log data while the server is powered on. When you
turn off the power to the server, the test log is cleared.
