speed can also be controlled by the fan speed settings in the (BIOS) Setup Utility.
Applying Power to the HP Server
Powering-Up the HP Server
NOTE
Turn on power to the monitor connected to the HP Server before you power-on the HP
Server. This allows proper auto-configuration of video output of the Server as it boots up.
CAUTION
To prevent damage to the power supply, check the Input Voltage selector switch before
connecting the Server and its power cord to a voltage source.
1. Ensure the Input Voltage selector switch is set for the correct input voltage, before connecting the power
cord to a voltage source. See Figure 2-4.
Power
Connector

115 volts position.)

2. Ensure the HP Server's power cord is connected to the power source. See Figure 2-4.
3. Press the Power button on the lower front bezel. See Figure 2-1.
When you press the power button on the front bezel, the Server powers up and loads the operating
system. The system runs a set of Power On Self Tests (POST) during this process. For details refer to
Chapter 8, "Configuring the HP Server" and Chapter 9, "Troubleshooting."
Powering-Down the HP Server
1. Log off all users and if necessary, back up files.
o Schedule the power down for a time when the fewest users will be affected by the Server's
downtime.
o If you will be doing any kind of hardware or software upgrade, be sure your Server's data has been
backed up.
2. Follow instructions in your network operating system (NOS) documentation to gracefully shut down all
networking software and applications.
3. Press the power switch on the HP Server's control panel when prompted by the operating system.
Normally this completes the power down procedure.

Chapter 2
Controls, Ports, and Indicators
NOTE
The power supply will continue to provide standby current to the Server until the power
cable is disconnected from the rear panel.
Multiple-Server Configurations
The HP Server temporarily draws a large "inrush current," when first connected to an AC power source. This
also occurs when the Server is in a standby mode (power is turned off and the power cord is plugged into AC
power). The inrush current is much greater than the Server's normal operating current and generally, the AC
power source can handle the normal inrush current.
However, if you install several HP Servers on one circuit, precautions are necessary. If there is a power
failure and power is then restored, all the servers immediately begin to draw inrush current at the same time.
If the circuit breakers on the incoming power line have insufficient capability, the breaker may trip and thus
prevent the servers from powering up.
When preparing your site for installation, allow for the additional inrush current. See "Power Specifications"
in Chapter 1.
Sleep States (ACPI)
The HP Server supports the ACPI (Advanced Configuration and Power Management Interface) standard,
which is a key component of a NOS's directed power management. The supported features are only available
when an ACPI-compliant NOS is installed on the Server. The term “sleep state” refers to any of several
reduced power consumption states in which normal NOS activity has ceased.
The Server supports several sleep states, including a sleep state with a short wake-up time, sometimes
referred to as “standby” or “suspend” by various operating systems. In this sleep state the Server appears to
be off, and is indicated by no display on the monitor and no activity for the CD-ROM or internal hard drives.
However, the power LED is a steady orange and the fans are operating.
The Server may also support another sleep state with a slower wake-up time, sometimes referred to as
“hibernate” by various operating systems. In this sleep state, the Server appears to be off as described earlier,
but the system fan and the front panel power LED are also turned off. The unique feature of this sleep state
(and the reason for its slower wake-up time) is that information about the Server’s NOS state (open
applications, screens, and so on) is saved to disk before the Server is placed in the sleep state. Upon wake-up,
this information is restored from disk. This method of restoring the Server's operation is much faster than a
complete rebooting of the Server. It still requires running all the start-up self-tests before starting the NOS,
but loading the NOS and all the previously opened applications is much faster.
The Server supports certain types of system activity, which are used as wake-up events from sleep states.
These wake-up events can be generated from the power button, keyboard and mouse activity, and scheduled
events.
NOTE
The HP Server’s power management policies (transitions between various power states)
and the user options are specific to the particular ACPI-compliant NOS installed on the
Server. If your respective NOS is ACPI-compliant, refer to the (BIOS) Setup Utility and
the power management features described in the instructions provided for more
information.
The HP Server’s power button can be configured to initiate a graceful shutdown or "soft off" of the NOS,
rather than an immediate shutdown of the power supply. The power button configurations are dependent on
the user interface provided by the ACPI-compliant NOS. While power management is under the control of
the ACPI-compliant NOS, the HP Server’s power button is capable of an override in case of a non-responsive
NOS.
NOTE
The HP Server power button will force a power down without waiting for the NOS to
gracefully shut down the Server when the power button is pressed and held in excess of
four seconds.

Controls, Ports, and Indicators
CAUTION
If the power button override is used; there is a strong possibility of corrupted or lost data.
Refer to the BIOS Setup Utility in Chapter 8, “Configuring the HP Server” and your NOS documentation for
instructions on setting up Sleep States and transitioning into and out of the various states.

4 Maintenance Guidelines
Introduction
This chapter provides the HP Tower Server tc2100’s maintenance guidelines when removing or replacing the
mass storage devices, DIMM memory, accessory boards, and processors.
Mass Storage
The HP Server tc2100 comes standard with one IDE CD-ROM and one flexible disk drive with various
possible configurations of SCSI or IDE hard disk drives, depending on the model (SCSI or IDE). The Server
is limited to six internal mass storage devices (including a tape back up drive), four in the front shelves (or
common trays) and two in the removable drive cage accessed from the side of the Server.
Mass Storage Guidelines
•
General Guidelines
o Use care when unpacking and handling the hard disk drives.
The hard disk drives are very susceptible to mechanical shock and can be easily damaged by a drop
as short as one-quarter of an inch. If the drop would crack an egg, it will damage the drive.
o Do not stack drives.
o The Server is internally limited to 6 mass storage shelves.
The flexible disk drive and CD-ROM drive, which are standard on all models of the HP Server
tc2100, occupy shelves 1 and 2 respectively. The first four mass storage shelves may also be referred
to as common trays, or drive trays.
o If a backup tape drive is used, it occupies shelf 3, leaving only three mass storage devices available
for shelves 4-6, and at least one is required for the boot drive.
•
IDE Devices
o The embedded IDE controller is an Enhanced-IDE dual channel controller and provides two
connectors (IDE-1 and IDE-2) for IDE devices.
Refer to "System Board Layout" in Chapter 1, "Specifications."
o The IDE CD-ROM uses one connector on the cable from the IDE-2 connector, leaving one
connector for the optional third hard drive on the IDE model. The CD-ROM is configured as the
master device, unless a third HDD is installed, which should be configured for the master device.
For the SCSI model the second IDE-2 connector could be used for any additional IDE device, such
as IDE hard drive.
o The primary IDE connector (IDE-1) and cable is used for the first or standard hard IDE drive and the
second optional hard drive, but this cable is not provided for the SCSI model.
The bundled IDE CD-ROM and hard disk drive were put on separate IDE connectors to improve
performance.
•
SCSI Devices
o Use only low-voltage differential (LVD) SCSI devices
o Do not use high voltage differential (HVD) SCSI devices in the Server or damage to the controller
and other devices may occur.
o Ensure the SCSI devices you install do not have terminations installed.
The SCSI drives are connected to a terminated cable and do not require termination on the SCSI
drive.

Chapter 4
Maintenance Guidelines
o Use only HP Ultra-160 SCSI LVD (1-inch) low profile 3.5-inch hard disk drives for the removable
hard disk drive cage.
o Only use an HP Ultra-160 SCSI LVD drive as the optional third drive.
o The optional HP backup tape drive comes with a 50-to-68-pin adapter to connect to the 68-pin SCSI
connector on the SCSI cable used for connection of backup tape drive.
o The optional HP backup tape drive may slow down access time for the Ultra-160 SCSI hard drives.
If this is the case, HP recommends adding another single channel SCSI controller to control the
slower backup tape drive.
Boot Priority
The HP Server tc2100 is provided in two models, IDE or SCSI, and the model type affects the boot priority.
The HP Server searches for bootable devices in a specific order, which is set up in the BIOS Utility.
IDE Model Boot Order:
1. Flexible disk drive
2. IDE CD-ROM drive
3. IDE hard drive (boot drive)
4. PCI slot P1 (32-bit slot)
5. PCI slot P2 (32-bit slot)
6. PCI slot P3 (32-bit slot)
7. PCI slot P4 (32-bit slot)
8. PCI slot P5 (32-bit slot)
SCSI Model Boot Order:
1. Flexible disk drive
2. IDE CD-ROM drive
3. IDE hard drive (if boot drive)
4. SCSI devices
5. PCI slot P1 (32-bit slot)
6. PCI slot P2 (32-bit slot)
7. PCI slot P3 (32-bit slot)
8. PCI slot P4 (32-bit slot)
9. PCI slot P5 (32-bit slot)
The SCSI Controller in the Server scans for a boot device starting at device ID 0 and works up through the ID
numbers (0-15). The SCSI controller board is always SCSI ID 7. The optional backup tape drive will use
SCSI address ID 3.
NOTE
The boot order can be changed using the Server's (BIOS) Setup Utility and the SCSISelect
Utility.

Maintenance Guidelines
IDE Mass Storage Devices
This section provides the configuration of the IDE mass storage devices, if you have selected an IDE version
of the HP Server tc2100.
IDE Controller Configuration
The embedded IDE controller is available for both models (IDE or SCSI) of the HP Server. The embedded
IDE controller is an Ultra DMA33/66/100 E-IDE dual channel controller, which provides IDE-1 and IDE-2
connectors. Each channel can only control two IDE devices.
The IDE Server model uses the IDE-1 for the boot drive and the IDE-2 connector for the IDE CD-ROM. The
Setup Utility (BIOS) can be used to change the boot order of the flexible disk drive and the IDE devices.
Refer to Chapter 8, "Configuring the HP Server," for more information.
IDE Mass Storage Additions
The table below lists the number and types of mass storage devices in or may be added into the IDE model of
the HP Server.

SCSI Mass Storage Devices
This section provides the configuration of the SCSI mass storage devices, if you have selected a SCSI version
of the HP Server tc2100. The base SCSI model configuration has at least one SCSI hard drive (shelf 6)
located in the removable drive cage and connected to the factory installed SCSI controller.
SCSI Controller Configuration
The single channel SCSI controller board provided with the SCSI model uses the SCSISelect Utility, to
control the SCSI controller board settings. If you order the SCSI model, you typically do not need to
configure the SCSI controller, because the SCSISelect utility will automatically recognize all SCSI devices
connected to it.
Run the SCSI Select Utility to verify or modify the SCSI controller settings, low-level format SCSI disks, or
verify SCSI media. Refer to Chapter 8, "Configuring the HP Server," in the HP Server tc2100 Installation
Guide for further information.
CAUTION
You must not connect high voltage differential (HVD) SCSI devices on the SCSI bus or
you will damage the other LVD SCSI devices.
The single channel Ultra-160 PCI SCSI controller board provided with the SCSI model includes two SCSI
connectors and is normally installed in PCI slot P1. The SCSI cable provided has 5 connectors, (4 for SCSI
devices and 1 for the SCSI controller board) and one terminator on the end of the cable.
•
1 internal 68-pin connector – This internal connector is used to control the internal SCSI drives; up to a
total of four SCSI devices.

Chapter 4
Maintenance Guidelines
•
1 external 68-pin connector – This external SCSI connector is only used for external SCSI devices and
requires no additional internal cabling or switch settings. This connector supports up to 15 devices
connected to it externally.
NOTE
Only one 68-pin connector on the SCSI controller board can be used as the active SCSI
connector. Therefore, you can not connect external SCSI devices to the external connector
when there are active internal SCSI devices connected to the internal SCSI connector.
The HP Server tc2100 will support an HP NetRAID 1M controller board, separate from the SCSI controller
board.

drive installed and configured as master device. The primary IDE connector (IDE-1) is available on the SCSI model, but is not
supported by Hewlett-Packard.
** A 50-to-68-pin SCSI adapter is provided with the HP backup tape drive.
*** The single channel SCSI controller can support up to 15 devices on one connector at a time; however, there are only enough
internal storage shelves for 3 hard disk drives and 1 optional tape backup device. The external connector is only used to control
external SCSI devices when there are no internal SCSI devices.
External SCSI Connector
The HP Server tc2100, SCSI model, has an external SCSI connector at the rear of the Server. This SCSI port
cannot be used if there are active internal SCSI devices. The SCSI controller provided with the SCSI model
of the Server is a single channel controller and cannot support internal and external SCSI devices at the same
time.
Memory Guidelines
•
The HP Server tc2100 only uses 133 MHz (PC133) SDRAM DIMMs, which are electrically different
from the EDO and PC100 SDRAM memory modules used in previous HP Server models.
•
•
DIMMs sizes supported are 128 MB, 256 MB, or 512 MB buffered in any combination.
Supported memory capacity ranges from 128 MB to 1.5 GB maximum (512 MB per DIMM slot x 3
DIMM slots total). The minimum capacity is 128 MB (one DIMM).
•
DIMM sizes may be mixed on the system board and may be loaded in any order (1 through 3).
However, HP recommends starting at slot 1 and filling the slots in order: 1, 2, and 3.
Empty slots between DIMMs are permitted.
•
•
When handling DIMMs, observe anti-static precautions to avoid damage.
To ensure you have the correct DIMMs before installation, refer to one of the following for a list of qualified
DIMMs:

Chapter 4
Maintenance Guidelines
•
HP Customer Service
The video memory is limited to 4 MB on the system board and cannot be upgraded.
Accessory Board Guidelines
The system board in the HP Server tc2100 provides up to five 32-bit PCI slots (P1 through P5).
Tested PCI Boards
For a list of tested PCI boards, check for compatibility under the Hardware Tested Products list for the HP
Server tc2100 under the Technical Support topic for the specific NOS used in the Server at HP’s web site:
CAUTION
Some accessory board outputs may exceed U.S. National Electrical code (NFPA 70)
Class 2 or limited power source limits and must use appropriate inter-connecting cabling
in accordance with the National Electrical Code. (All HP boards comply with Class 2.)
IRQ Settings
The IRQ settings are automatically assigned and do not require user intervention. The HP Server uses the
Plug-and-Play feature of the PCI boards to correctly assign the resources automatically.
Processor Guidelines
This HP Server supports the Celeron and Pentium III processors and each one should have its own heatsink
and cooling fan.
CAUTION
If good contact is not made between the processor and the thermal patch on the heatsink,
the processor will overheat and possible damage may occur.
•
Ensure you open the ZIF lever before removing or installing the processor into the socket.
The processor socket uses a ZIF (Zero Insertion Force) lever to secure the processor in the socket.
The ZIF lever should make a clicking sound when it closes completely.
•
•
Ensure you align Pin-1 of the processor with Pin-1 of the processor socket when installing the
processor, or processor pins will be damaged.
•
Each processor requires a heatsink with a cooling fan attached.
The Celeron processors use a slightly different heatsink with a smaller cooling fan than the Pentium III
heatsink-cooling fan assembly.
CAUTION
To prevent damage to the thermal patch, do not slide the heatsink around on the
processor once it is in place. Rocking it slightly to one side or the other to install both
latches is acceptable.
•
•
Each heatsink should have an undamaged thermal patch on the bottom of the heatsink.
The thermal patch provides the thermal bonding between the processor and the heatsink.
The plastic sheet/tab on the thermal patch must be removed before placing the heatsink on the processor.
Some thermal patches come with a small plastic sheet (with a finger tab) covering the non-adhesive side
of the patch to help protect the thermal material.

Chapter 4
Maintenance Guidelines
•
Ensure the front ridge on the bottom of the heatsink fits into the groove between the processor socket
and processor and both ridges should straddle the processor.
The bottom of each heatsink has two ridges, which are used to align the heatsink with the processor.
•
Both latches (hook and thumb) on the heatsink must be connected to the processor socket base or the
processor will overheat.
The mechanical latches on the heatsink ensure a good thermal bond between the heatsink and the
processor through the thermal patch.
•
•
If the processor is upgraded to a faster processor speed with a different front side bus (FSB) speed than
the previous processor, the circuitry on the system board detects the change and automatically adjusts to
the faster front side bus speed.
The HP Server tc2100 only supports 100 MHz and 133 MHz FSB speeds.

6 Diagnostics
Diagnostic Tests
When the Server boots, a series of tests are displayed on the screen. The number of tests displayed depends
on the configuration of the Server. The following are the types of errors a user might get with the HP Server.
•
•
Built-in diagnostic Error Messages.
BIOS and other error messages. These are errors detected by the system BIOS outside the built-in
diagnostics or application errors.
To see the Power On Self-Tests (POST):
•
•
•
The HP Server must be functionally able to run the diagnostics.
The video system must be functional.
The keyboard must be functional.
NOTE
BIOS ROM version number is displayed on the monitor screen during power-up.
Diagnostics Description
The diagnostics (Power-On Self-Test "POST") run automatically each time the Server is powered on. These
diagnostics, which reside in the BIOS ROM, isolate server-related logic failures and indicate the board or
component that needs to be replaced, as indicated by the Error Messages. Most Server hardware failures will
be accurately isolated by the diagnostics.
WARNING
You should always turn off the power and disconnect the power cord to the Server before
attempting to remove the cover and touch the internal components. Failing to do so can
expose you to electric shock and the server's components to damage. The power switch
does NOT turn off standby power, so disconnect the power cord to turn off standby
power.
HP DiagTools
The purpose of hardware diagnostic software is to provide tools for checking hardware problems. By design,
diagnostic software executes simple tests of each hardware component. Usually, such tests assure the
hardware is not the source of Server problems. This allows the user to eliminate hardware as the cause of the
problem and to focus on operating system configuration parameters, network connections, and application
software configuration parameters as the source of the problem.
If hardware problems are confirmed, the diagnostic software program can sometimes detect and diagnose the
system or specific Server component causing the problem. In addition, diagnostic tools can capture
information that allows support personnel to quickly assess the condition of the Server.
In order to be effective, diagnostic software tools must be used in the context of a wider troubleshooting
procedure.
HP DiagTools Capabilities
HP DiagTools for HP Servers is a set of off-line diagnostic tests, including tests for system and processor
components, memory and storage elements, ports, and input/output devices. DiagTools is supplied on the HP
Startup CD-ROM.
37
Download from Www.Somanuals.com. All Manuals Search And Download.
Chapter 6
Diagnostics
The HP DiagTools Utility is run from the Startup CD-ROM, which is a bootable CD-ROM when inserted
into the CD-ROM drive and the Server is rebooted. A basic suite of tools checks key Server components, and
a menu of advanced tests is available for in-depth testing.
DiagTools has the ability to test the following components:
•
•
•
•
•
System board
•
•
•
•
Processor
Memory modules
Flexible disk drive (FDD)
Parallel ports
Hard disk drives (HDD)
Keyboard
CD-ROM drives
Video monitor
DiagTools is an off-line diagnostic. Off-line diagnostics do not use the main network operating system (NOS)
of the HP Server. The alternate DiagTools OS has far fewer features than the full-fledged NOS. Thus, its
capabilities are limited to a set of basic tests and a series of advanced tests. In addition, DiagTools does not
use any tests, which might write over and thus destroy user data. Tests that require user inputs or decisions
are left to the advanced series of tests.
You can use DiagTools to perform the tasks listed below:
•
•
•
•
•
•
•
•
•
•
•
•
Display a high-level inventory of the Server under test
Save and print a detailed inventory of hardware components
Conduct a basic test of components listed in the Server inventory
Display “PASSED” or “FAILED” overall results of basic tests
Record detailed test results of basic Server tests
Display a menu of advanced tests
Select and run one or a series of advanced tests
Add the record of results of advanced tests to the record of basic tests
View a list to locate the meaning of a specific error code
View one or more steps to help confirm and isolate error conditions
Browse the Support Ticket, which contains the detailed inventories and test results
Add comments to the Support Ticket
About Error Messages
A hexadecimal number designates each error message reported by DiagTools; a short note on the type of
error; and a list of one or more steps the user can take in response. When you run a test, it exercises many
aspects of the hardware, so the number of possible error messages exceeds 300. Most of these are
encountered rarely, if ever.
Error codes can be viewed on line from the DiagTools User menu within the advanced series of tests, or you
can refer to Chapter 3 of the HP Server DiagTools Error Reference and User Guide.
Advantages and Limitations of Hardware Diagnostics
Off-line diagnostic software is useful in making sure the hardware has been eliminated as the cause for
possible Server problems. Such diagnostic tools can easily be shipped with a server, and they are relatively
easy to use.
Only experienced personnel knowledgeable of its limitations should use off-line diagnostic software.
Some limitations are:
•
Booting the Server from the Startup CD-ROM
38

Chapter 6
Diagnostics
•
No access to operating system error logs, since the OS is not operating at the same time as the
diagnostic tools
•
•
Limited ability to test only a single component at a time
Inability to indicate problems with wrongly configured Servers or the network

Chapter 7
Maintenance and Troubleshooting
Symptom:
•
The CD-ROM drive is not working properly
The CD-ROM drive provided with this HP Server (SCSI or IDE models) is IDE CD-ROM. If the CD-ROM
drive does not work, do the following:
1. Review the basic IDE installation guidelines to ensure a proper configuration.
2. In addition, check the following:
o Verify correct drivers are installed.
o Verify there is a CD-ROM disk in the CD-ROM drive.
o Verify all internal drive cables are securely attached and functional.
3. If the drive is a Hewlett-Packard CD-ROM drive, review the CD-ROM Installation Guide for any
special installation instructions.
4. Try installing a known good CD-ROM disk.
5. If the problem persists, check for environmental problems that could damage disk media and disk drive
heads.
Environmental problems result from:
o Radiated Interference: Sources include communications and radar installations, radio/TV broadcast
transmitters, and hand-held receivers.
o Airborne Contaminants: Sources include dust, smoke, and ashes. Steam from duplication equipment
may result in intermittent disk errors.
Symptom:
•

This ensures the CD-ROM will boot before any of the hard disk drives (IDE or SCSI).
5. Save and exit the Setup Utility.
SCSI Problems
Symptom:
•
The SCSI BIOS has trouble loading
If the Server has trouble loading the SCSI BIOS, do the following:
1. Review the Troubleshooting Checklist before you continue.
2. If you installed more than one SCSI controller, verify the BIOS of all other SCSI controllers are
disabled except for the SCSI boot controller.
This lets the SCSI BIOS for the boot controller board load, preventing conflicts from the other SCSI
controllers. If necessary, remove the other SCSI controller boards, except the SCSI boot controller
board, until you resolve the current problem.
3. Determine what the boot order is for this Server model.
4. Verify the SCSI controller board is in the right place in the boot order.
5. Verify the SCSI boot drive (address ID = 0) is in the right place in the boot order.

Chapter 7
Maintenance and Troubleshooting
Symptom:
•
The SCSI controller board does not work during installation
Usually an incorrect configuration and not faulty hardware causes most of the SCSI problems encountered
during installation. If the SCSI controller does not work after installation, do the following:
1. Review the Troubleshooting Checklist and Mass Storage Guidelines before you continue.
2. Run the HP DiagTools Utility and verify the following items:
o The integrity of the SCSI bus
o Ensure the switch settings on the internal SCSI devices are correct (no termination and manually set
SCSI IDs).
o Verify each SCSI device is assigned a unique SCSI ID.
3. If you do not see the SCSI BIOS banner during Server startup, similar to the one listed below:
<<<Press <Ctrl A> for SCSISelect Utility!>>>
o Check the cable connections.
o Check the SCSI termination.
4. Check the (BIOS) Setup Utility and the SCSI Configuration Utility to verify the SCSI controller board
(or host bus adapter - HBA) is properly configured.
The SCSI controller board should be configured as SCSI address ID = 7.
5. If you installed more than one SCSI controller, verify each controller is set to a separate BIOS address;
or disable the BIOS on all of the controllers except one.
If necessary, remove the other SCSI controller boards, except the SCSI boot controller board, until you
resolve the current problem.
For each SCSI device, verify:
a. The SCSI device has a unique SCSI address.
b. In general, select as low a SCSI address as possible, when selecting an address for the boot drive
(default address = 0).
c. The SCSI device's jumpers are set according to the device documentation (no termination and
manually set SCSI IDs)
d. The hard disk activity light cable is properly installed.
6. Verify the boot SCSI hard disk drive is set to the lowest address (usually set to 0).
Each SCSI device (the SCSI controller is also a device) must have a unique and separate SCSI ID
number.
o To solve this problem, simply set the SCSI device ID to something other than one reserved for the
SCSI controller (ID address = 7).
o If the SCSI device is a boot drive, then the SCSI ID should be set at ID address = 0.
7. If another hard disk drive is connected to the SCSI bus, check it for a unique address, SCSI cable
connection, and power connection.
8. Check the SCSI bus cable for correct orientation, alignment, and seating on the SCSI adapter and the
SCSI device.
9. Check for the correct Hewlett-Packard internal SCSI cables.
This Server uses a cable with five connectors and one termination at one end of the cable.
10. Verify all SCSI devices are connected to power, and verify all SCSI devices power on at the same time
as the Server to ensure a stable SCSI bus.
11. Watch the boot screen and verify all SCSI devices are displayed.

Chapter 7
Maintenance and Troubleshooting
For example, in this Server with 1 SCSI controller and 2 hard disk drives (one with ID 0 and one with
ID 1), if a valid device is found at device address 0, but not at address 1, you would see these device
validation lines on the boot screen:
Channel x, SCSI ID #n - id info - Drive C: (80h)
If you see this message:
a. Verify the SCSI hard disk drive is set to address 1.
b. Check the SCSI bus cable for correct orientation, alignment, and seating on the host adapter and the
hard disk drive.
c. Verify the termination is installed at the end of the SCSI cable, but not on any of the SCSI devices.
d. Verify all SCSI devices on the bus are appropriate for the SCSI bus.
This HP Server supports Ultra-160 LVD devices on the SCSI bus, but the optional HP Backup Tape
drive is a single-ended SCSI device and may slow down disk access time. If you are having SCSI
problems, you may disconnect the backup tape drive, until you resolve the SCSI problems.
12. If the Server still fails to recognize the SCSI drive, disconnect all SCSI devices except the SCSI
controller and the drive at SCSI address 0 and try again.
13. If the Server fails to recognize the SCSI hard disk drive, try substituting a known good hard disk drive.
14. Check the following steps if you find:
o The SCSI BIOS has properly identified device 0 and has installed it as drive C, but cannot find a
device at address 1.
o If no further messages are displayed, this indicates the Server cannot load the operating system from
device 0
15. If a second hard disk drive is connected to the SCSI bus, check it for proper address selection, SCSI
cable connection, and proper power.
16. Partition the hard disk drive if required.
17. Use only SCSI devices without built-in terminators.
o The HP SCSI controllers are terminated automatically at the end of the SCSI cable. If you are
installing a SCSI device that uses a built-in terminator, you must remove the terminator from the
device before proceeding with the installation.
o Use only HP SCSI cables for the SCSI devices, as these have terminators at the end of the cable.
18. Disconnect all SCSI devices except the SCSI controller board and the drive at SCSI address 0, and try
again.
19. If this fails, try substituting a known good SCSI controller board and disk drive.
20. Use the Setup Utility to check for resource conflicts, especially if new boards or accessories have been
added.
Symptom:
•
The SCSI devices stop working
If the SCSI devices should stop working, do the following:
1. Review the Troubleshooting Checklist and Mass Storage Guidelines before you continue.
2. Run the HP DiagTools Utility and:
a. Verify the SCSI IDs and any relevant switch settings are correct.
b. Verify the problem is the SCSI bus, by looking for specific information.
3. If an accessory board was added recently, check for a resource conflict between the new board and an
existing accessory boards.
4. Also, if you have changed the options on an existing board, there may be a resource conflict:
56
Download from Www.Somanuals.com. All Manuals Search And Download.
Chapter 7
Maintenance and Troubleshooting
a. Remove the new board and restart the Server.
b. If this corrects the problem, the board is either defective or it is trying to use a system resource used
by the SCSI controller board.
c. Check if the board is using memory, I/O addresses, or interrupt lines that are also used by the SCSI
controller board.
5. Check for any recent changes or upgrades to the software.
For example, has anyone moved, removed, or changed the configuration files or drivers? Refer to the
software documentation for more information.
6. If you suspect hardware failure and there are no system error messages, check each component
associated with the failure.
Equipment failure is probably the most unlikely reason for a SCSI devices failure.
Symptom:
•
The external SCSI devices do not work after installation
NOTE
The SCSI controller board normally supplied with this HP Server is a single channel SCSI
Controller board and can not support internal and external SCSI devices at the same time.
If the external SCSI devices do not work after installation, do the following:
1. Review the Troubleshooting Checklist and read the Mass Storage Guidelines.
2. Run the HP DiagTools Utility and verify the following items:
o The integrity of the SCSI bus
o Verify the switch settings on the external SCSI devices are correct.
o Verify each SCSI device is assigned a unique SCSI ID.
Refer to the documentation provided with the SCSI devices for any specific information regarding
installation.
3. Ensure all installed SCSI controllers are installed and configured correctly.
4. If the SCSI devices installed in an external enclosure connected to the Server chassis operate in Ultra
SCSI or Fast SCSI mode, this may be the problem for this Server.
The SCSI controller board and the internal SCSI devices normally provided with this Server operate in
the Ultra-160 SCSI mode. The external SCSI devices may be slowing down or causing the internal
SCSI controller board to be in effective and therefore non-operational.
5. Check the SCSI cables for problems that may have been caused by recent Server maintenance, hardware
upgrades, or physical damage.
6. Check the ROM BIOS version to ensure it is the most recently issued version.
7. Verify the external SCSI BIOS is being executed properly.
o When you start the Server, the incrementing count of the RAM appears on the screen. Then the
external SCSI BIOS displays a banner and a copyright notice.
o The BIOS then checks for valid devices on the SCSI bus, and reports which devices are found. If
you have installed and configured the SCSI devices correctly, you will see a list confirming all SCSI
devices installed in the Server.
o If the banner is not displayed, the external SCSI controller is not recognized.
8. Verify the external SCSI bus is terminated at both ends.
By default, HP SCSI controllers in external enclosures are terminated. When a device is connected to a
connector on the SCSI bus of the controller, bus termination for that connector is disabled. Verify the
last device on the bus is terminated.
57

Chapter 7
Maintenance and Troubleshooting
9. Ensure no SCSI device is set to SCSI address ID = 7.
This address ID is the reserved for the SCSI controller.
10. Verify all SCSI devices are low voltage differential (LVD) SCSI devices, and there are no single-ended
devices on the bus.
11. Verify the SCSI hard disk drive that loads the operating system is set to the lowest SCSI address
(usually set to 0).
12. If a second hard disk drive is connected to the SCSI cable, check it for proper SCSI address, SCSI cable
connection, proper power, and jumper settings.
13. Disconnect all SCSI devices except the integrated SCSI controller board and the drive at SCSI address
0, and try again. If this fails, try substituting a known good SCSI controller board and a good hard disk
drive.
Processor Problems
In this Server, the typically problems you may experience are because the processor is overheating due to
incorrect installation of the heatsink-cooling fan on the processor or a damaged thermal patch.
1. Remove and reseat the heatsink-cooling fan.
This may require a new thermal patch before replacing the heatsink-cooling fan.
2. Check the condition of the existing thermal patch on the bottom of the heatsink before replacing the
heatsink-cooling fan.
3. Verify the cooling fan is connected to its power connector properly and there is voltage to the fan.
4. Remove and reseat the processor, ensuring the ZIP lever is completely down.
5. Replace each of these components, one-at-a-time, with a known-good component, and retest the Server:
o Heatsink-cooling fan (with a good thermal patch)
o Processor
CAUTION
Do not push on the processor components; push only on the edge. Pushing on the device
may damage it.
6. If the fault persists, replace the system board.
Memory Problems
The memory modules used for this Server are DIMMs.
NOTE
If the POST (displayed at power-on time) indicates a defective memory module, replace
it.
1. Review the Troubleshooting Checklist before you continue.
2. If memory problems are being experienced, power the Server off and on. This performs a "cold" restart,
rather than a "warm" restart (as it does when you press Ctrl+Alt+Del).
3. Check the BIOS event log (available on certain Server models) for messages indicating memory errors.
4. Run the HP DiagTools Utility memory test.
5. Reseat the memory modules.
6. To check that the modules are installed and configured correctly:
a. Run the (BIOS) Setup Utility and check the configuration.
b. Install one known good DIMM. If you still receive an error, replace the system board.
58

Chapter 7
Maintenance and Troubleshooting
c. If the error goes away, add another DIMM and reboot again.
d. Continue this process until you have installed all DIMMs or you experience a failure.
e. Replace the defective DIMM.
7. Once a suspect part has been found, verify the cause of the problem by reinstalling the part and
attempting to duplicate the error. Also install it in another memory socket to confirm whether or not the
socket is defective.
Embedded Network Interface Card Problems
See the appropriate Network Interface Card documentation and you may also follow where possible the
troubleshooting steps for the installed Network Interface Card in the following procedure.
Network Interface Card (Installed) Problems
See the appropriate Network Interface Card documentation.
Symptom:
•
If the NIC adapter can not connect to the network
1. Ensure the cabling is installed properly.
2. If you're directly connecting two Servers (with no hub or other device), use a “crossover” cable.
Most hub and switch connections require a straight-through cable; but consult the documentation.
3. Verify there are no resource conflicts between the NIC and any other accessories in the Server.
4. Check the (BIOS) Setup Utility for resource conflicts.
5. Check the LEDs on the adapter at the back of the Server to see if any show activity.
No lit LEDs probably indicate a bad network cable, hub connection or other network error.
6. Ensure you're using the latest and most correct drivers.
7. Verify the drivers are intended for this NIC adapter.
8. Ensure the port on the switch or hub (or other device) has the same duplex setting as the adapter.
9. If you configured the adapter for full duplex, make sure the switch port is also configured for full
duplex.
Setting the wrong duplex mode can degrade performance, cause data loss, or result in lost connections.
10. Test the adapter as directed in the installation tasks for each operating system.
11. Also check the “README” files on the support disk provided by the NIC adapter vendor.

4. Place the processor on a static-dissipating work surface or into an anti-static bag.
Replacing the Processor
1. Locate the pin-1 marker on the processor before installing the processor.
NOTE
If you are upgrading the processor to a faster processor speed with a different front side
bus (FSB) speed than the previous processor, the system board will automatically detect a
need for a faster FSB speed and change accordingly. However, this Server only supports
100 MHz and 133 MHz FSB speeds.
2. Open the ZIF (Zero Insertion Force) lever to allow access to the processor socket.
Pull the ZIP lever up and away from the ZIF socket and then raise it to a full 90° to the system board.
3. Align the processor over the empty processor socket.
The socket has a mark for pin-1 that should match the mark for pin-1 on the processor near the end of
the ZIF lever.
CAUTION
Ensure you align pin-1 of the processor with pin-1 of the processor socket or pin damage
will occur.
4. Insert the processor into the socket and close the ZIF lever to fully seat the processor.

Replacing the Heatsink-Cooling Fan
Once the processor is installed, the heatsink-cooling fan must be installed on top of the processor. Each
processor requires a heatsink, with its cooling fan attached, and a thermal bonding between the processor and
the heatsink, provided with a thermal patch. The heatsink is mechanically connected to the processor socket
with both latches, mechanically making contact with processor through the thermal patch.
CAUTION
To prevent overheating or a possible system crash, do not use the Celeron heatsink-
cooling fan assembly on a Pentium III processor. The Celeron heatsink-cooling fan
assembly uses a smaller fan and a little different heatsink and should not be used on the
Pentium III processor.
1. Remove the heatsink-fan assembly from the shipping container and ensure you do not touch the thermal
patch on the bottom of the heatsink.
2. Verify the thermal patch has not been damaged (missing thermal material from the patch) and if
necessary, remove the plastic tab protecting the thermal patch.
Some thermal patches have a small plastic sheet (with a finger tab) covering the non-adhesive side of
the patch to help protect the thermal material. This plastic sheet/tab must be removed before placing the
heatsink on the processor. The thermal patch used for the Celeron processors is smaller than the
thermal patch used by the Pentium III processors.
3. If the thermal patch has been damaged, peel it off the heatsink and replace it with a new one from the
installation kit.
It may help to use a felt-tip pen to mark an outline around the thermal patch on the bottom of the
heatsink, before removing the old patch. This may help you place the new patch on the heatsink.
4. Ensure the latches are free and pointing away from the heatsink.
CAUTION
To prevent scratching off some of the thermal material, do not slide the heatsink around
on the processor once it is in place. Rocking it slightly to install the hook latch is
acceptable.
5. Position the heatsink over the processor and use one of two methods:

Chapter 9
Remove/Replace Procedures
Method A
a. Position the heatsink over the processor socket and lower it squarely onto the processor, as shown in
the following illustration.
There are two ridges on the heatsink to help align the heatsink to the processor. The heatsink can
only be installed in one direction, with the metal step to the right of processor socket, as shown in
the following illustration.
b. While holding the heatsink steady with one hand, push down and in toward the center with your
finger to hook the tab with the hook latch.
The hook latch and thumb latch both hook underneath the tabs extending from the base of the
processor socket.
c. While holding the heatsink down with one hand, push down with your thumb to hook the tab with
the thumb latch, as shown in the following illustration.

CAUTION
Ensure the front ridge on the bottom of the heatsink fits into the groove between the
processor socket and processor, while both ridges should straddle the processor. If good
contact is not made between the processor and the thermal patch on the heatsink, the
processor will overheat and possible damage may occur.
Method B
a. Tilt or roll the heatsink slightly to the rear of the chassis to help engage the hook latch and then
connect the hook latch to the tab.
The hook latch and thumb latch both hook underneath the tabs extending from the base of the
processor socket.
b. Rotate the heatsink back and ensure the front ridge on the bottom of the heatsink rest between the
processor and the edge of the processor socket base, before placing the heatsink squarely on top of
the processor.
There are two ridges on the heatsink to help align the heatsink to the processor. The ridges on the
heatsink use the edge of the processor and the processor socket base to correctly position the
heatsink on the processor.
c. Connect the thumb latch to the tab on the base of the processor socket.
