HP Server – Rear View

• The power connector accepts a standard power cable to connect the HP Server tc2100 with the site

power source.

• The input voltage selector switch is used to adapt the power supply to the input line voltage. The two

switch settings are 115 volts or 230 volts, and 230 volts is the default setting.

• The mouse port accepts a standard mouse with a PS/2 connector.

• The keyboard port accepts a standard keyboard with a PS/2 connector.

• Two USB ports are provided for printers, external modems, a keyboard and a mouse, but these features

are NOS dependent.

• The COM 1 port is a standard serial port.

• The Parallel Port is a standard parallel printer port, which supports Extended Capabilities Port

(ECP)/Enhanced Parallel Port (EPP).

• The Monitor Port (SVGA) interface specifications are listed in the following tables "HP Server

Hardware Specifications" and "Video Display Modes" of Chapter 1, "Specifications."

• The COM 2 port is a standard serial port.

• The SCSI model has an external SCSI port for external SCSI devices provided by the single channel

SCSI controller board, but can only be used when no SCSI devices are connected internally.

• Keylock mechanism provides mechanical security for the left side panel to prevent access to the internal

components.

Chapter 2 Controls, Ports, and Indicators

• The LAN port is included as an embedded controller based on Intel's 82559 10/100 BaseT Fast Ethernet

Controller. It has a RJ-45 LAN connector on the rear panel. The LED on the front panel is used to indicate LAN activity.

• System Fan is a variable speed fan controlled by thermal sensors on the system board. The system fan

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 Serv er

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

(Switch show n in 11 5 vol t s 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."

Power ing -Do wn the HP Ser v er

1. Log off all users and if necessary, back up files.

Input Voltage Selection Switch

Input Voltage Switch

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 Configurat ions

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 general ly, 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 (AC PI)

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 tha n 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.

Chapter 2 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.

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 G uidelines

• 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.

Chapter 4 Maintenance Guidelines

IDE Mass Storag e Device s

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 Stor age Dev ices

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.

** A 50-to-68-pin SCSI adapter is provided with the HP backup tape drive. *** The single channel SCSI controller c an support up to 15 devices on one connect or at a time; however, there a r e only enough

internal storage shelves for 3 hard disk drives and 1 optional tape backup device. The external connector is only u sed to control external SCSI devices when th er e 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:

• HP Order Assistant on the HP web site at:

Chapter 4 Maintenance Guidelines

http://www.hp.com/go/Server

• 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 Board s

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:

http://Server.hp.com/Server/support/compatibility/compatibility.asp

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-co oling fan a ssembly.

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 fron t 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 func tional.

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-li ne 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.

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

• Memo ry module s • Hard disk drives (HDD)

• Flexible disk drive (FDD) • Keyboard

• Parallel ports • 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 test s. 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 te st

• 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 b a sic 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 Limita tions of Hard ware 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

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

7 Maintenance and Trou bleshooting

Preventive Maintenance Procedures

Refer to the following table for preventive maintenance procedures used for the HP Tower Server tc2100. Be sure to turn off power to the Server when cleaning it.

Preventative Maintenance Procedures

Component Time Frame Maintenance Procedure

Keyboard Regularly Dust with damp, lint-free cloth. Monitor screen Regularly Use "HP Video Screen Cleaning Solution" found in 92193M

Master Clean Kit.

Mouse Regularly Refer to the mouse's manual for mouse maintenance

procedures.

Tape drive heads Monthly Use "Magnetic Head Cleaning Solution" found in the

92193M Master Clean Kit.

Cooling fans and grilles 6 Months Check cooling fan operation and clean the air intake openings

on the chassis by removing any dust, lint, and other obstructions to airflow.

CAUTION Do NOT use petroleum-based cleaners (such as lighter fluid or cleaners containing

benzene, trichlorethylene, ammonia, dilute ammonia, or acetone. These chemicals could damage the keyboard's plastic surfaces. )

HP recommends the periodic cleaning of tape heads, capstans, and guides on HP tape drive units and those products using high-density data cartridges and mini-data cartridges. These maintenance procedures prolong tape and head life and helps reduce read/write errors due to dust and oxide.

Troubleshooting

WARNING Before removing the left side cover, always disconnect the power cord and unplug

telephone cables. Disconnect telephone cables to avoid exposure to shock hazard from telephone ringing voltages. Disconnect the power cord to avoid exposure to high energy levels that may cause burns when parts are short-circuited by metal objects such as tools or jewelry.

• Use the HP DiagTools Utility whenever possible to detect hardware problems.

• For problems with a HP NetRAID controller, refer to the appropriate HP NetRAID manuals.

Troubleshooting Checklist

To troubleshoot an installation problem, do the following:

• First, ensure the Server is configured properly.

Most Server problems are the result of incorrect BIOS and SCSI configurations.

• If it is a network-related error, determine if the Server has enough memory and hard disk drive capacity.

Consult your network op erating system manual a nd its requirements.

• Verify all cables and boards are securely plugged into the appropriate connectors or slots.

Chapter 7 Maintenance and Troubleshooting

• Remove all options added since the Server was received and then add one option, and only one option,

at a time.

NOTE If the Server has a large amount of memory installed, it may take 30 seconds for the first

screen to display.

If it is a hardware error, follow these steps:

BIOS Recovery

Should you experience compatibility or stability issues with your Server, HP recommends starting your troublesho ot in g b y first up d at i ng yo ur B IO S, whic h ma y fi x your curr e nt pro b le ms. If the B I OS has become corrupted, it is possible to perform a BIOS reset, recovery, or update to correct the condition. A BIOS update/recovery diskette is created when the most current BIOS is downloaded from the HP web site to be used in flashing the BIOS into the Server. To perform a reset, an update, or a BIOS recovery, perform one of the following procedures.

Chapter 7 Maintenance and Troubleshooting

BIOS Reset

If you need to reset your BIOS settings to the factory defaults (the HP recommended values) due to possible corruptions, perform the following steps. The default values have been selected to optimize the HP Server’s performance.

1. Reboot the Server in a normal manner and press <F2> to enter the BIOS Setup Utility.

2. P r ess <F9> to load default values.

3. P r ess F10 to save changes and exit the BIOS Setup Utility.

BIOS Update

Use this procedure if you need to update your server BIOS with the latest BIOS version. HP regularly posts a new version of the HP Server tc2100 BIOS on the website to improve the Server’s performance.

1. Prepare a blank and formatted 3 ½” disk.

2. Insert this diskette to any Win d ows PC with HTML browser and a connection to the internet.

3. Locate and download the latest HP Server tc2100 BIOS to this diskette from HP’s web site at: http://www.hp.com/

This downloaded BIOS on the diskette becomes the BIOS update diskette.

4. Boot the Server with the BIOS update diskette in the flexible disk drive.

This action will automatically flash the BIOS from the diskette to the Server.

5. Remove the BIOS update diskette and then reboot the Server.

6. Make the necessary changes to the (BIOS) Setup Utility and save the BIOS changes.

7. Label, date, and save this flexible diskette for use as a BIOS Recovery diskette.

BIOS Recovery

Use this procedure if the BIOS has become corrupted and you want to restore the BIOS with your BIOS update/recovery diskette. A BIOS update/recovery diskette is created from the download of the latest BIOS from the HP web site. This diskette will be used in flashing the BIOS into the Server.

1. Use the BIOS Update diskette you created from the BIOS download described in the previous

procedure.

2. Bo o t the Server with this BIO S Up d a te diskette in the flexible disk drive.

This action will automatically flash the BIOS from the diskette to the Server.

3. Remove the BIOS update diskette and then reboot the Server.

4. Make the necessary changes to the (BIOS) Setup Utility and save the BIOS changes.

Password Problems

There are only two ways to reset forgotten or lost passwords for the HP Server:

• Clear CMOS – This clears all settings in the (BIOS) Setup Utility, but requires you to reset the settings

in the Setup Utility.

• Reset the supervisor password – This clears the supervisor password and forces the user password to

reset by clearing it when the supervisor password is cleared.

Clearing the BIOS Configurat ion

You may need to clear the BIOS configuration (CMOS) if the configuration has been corrupted, or if incorrect settings made in the Setup Utility have caused error messages to be unreadable.

To clear the configuration:

Chapter 7 Maintenance and Troubleshooting

1. Turn off power to the Server and remove the left side cover.

2. Move the jumper from its “Normal” position (Pins 1 & 2) on the system board to the “Clear CMOS” position (Pins 2 & 3) and leave it there for five seconds as shown in the figures below.

3. Return the jumper on the syste m bo ard to the “Normal” position (Pins 1 & 2).

4. Replace the left side cover.

5. T urn on power to the Server and the following message displays:

Incorrect System Configuration

6. Press <F2> to run the Setup Utility when <F2=Setup> appears.

7. Make any configuration chan ges required or load the default BIOS settings for optimal configuration.

8. Choose the Exit optio n, to save changes and retain the configuration settings, and exit the Setup Utility.

Resetting a Lost Password

If you have forgotten the User password, the Supervisor can reset it for you (by clearing the Supervisor password), but if the Supervisor password has been lost or forgotten you can only reset it by clearing the CMOS memory and all of the settings in the (BIOS) Setup Utility. Refer to t he pr evious section, “Clearing the BIOS Configuration” for instructions.

NOTE If you have forgotten the User Password or the Supervisor Password, your Server will

function normally, but you will not be able to access the configuration settings in the Setup Utility. If you have enabled the Password -on-Boot feature and have forgot ten all the passwords (User and Supervisor) you will not be able to reboot the Server successfully.

General Server Problems

No lights are on and no error mess age appears

If the Server does not work (no LEDs are on) and no error message appears, check the following:

Chapter 7 Maintenance and Troubleshooting

1. Verify the power is good and available.

2. Ensure the Server is turned on (the power-on light should be green and the fans should be on).

3. Turn the Server off and unplug the power cord. a. Wait 30 seconds and plug the power cord back in. b. Turn the Server back on. c. Verify the failure.

4. Verify all boards are installed properly and seated firmly in the slots with cables firmly connected.

5. If you have added any memory, make sure the DIMMs are seated properly on the system board.

If the Server now works, go to Step 8.

7. If the Server still does not work, remove all the accessories you have installed (do not remove the flexible disk drive, CD-ROM, or the bundled hard disk drive) and turn on the Server.

8. If the Server now works, turn off the Server and: a. Add one accessory at a time to determine which one is causing the problem. b. Turn on the Server after installing each board or option. c. When the problem returns, the last board or option installed is defective.

Operating system or an application is not responding p roperly

1. In Server models with accessible cache feature, determine if the memory cache feature is turned on or off.

Memory cache may need to be turned off for some older software. It may also need to be turned off for those accessory boards that have on-board firmware, and for those boards that use memory-mapped I/O.

2. If necessary, turn off the memory cache feature. a. Check the state of memory cache and, if necessary, disable it: b. Push <F2> during the boot process. c. Go to configuration and turn off Memory Caching.

Server stops working (hangs)

Typically, if the Server hangs before the end of POST completes, the problem is probably a hardware failure. If the Server hangs after the POST completes, the problem is probably due to an incorrectly configured or corrupt driver, operating system, or application program, or a media (disk drive) error.

If the Server stops working, try the following:

1. Review the Troubleshooting Checklist before you continue.

2. Power down the Server and unplug the power cords.

3. Wait 30 seconds and plug the power cords in and power on the Server.

5. If you installed more than one SCSI controller, verify each controller is set to a separate B IOS addr ess; 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. T he hard disk activity lig ht 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 prob lems.

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 t he 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:

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 cont ro llers 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.

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 driv e 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-co o li ng fa n.

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 t he 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.

Chapter 7 Maintenance and Troubleshooting

c. If the error goes away, add another DIMM and reboot again. d. Contin ue this p r ocess 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 Int erface Card P roblems

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 C ard (Inst alled) Problem s

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.

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, mec hanically 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 befor e 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 o ver 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 sh own 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.
