ENERGY STAR
Hewlett-Packard computers marked with the ENERGY STAR® Logo are compliant with the applicable
U.S. Environmental Protection Agency (EPA) ENERGY STAR specifications for computers. The EPA
ENERGY STAR Logo does not imply endorsement by the EPA. As an ENERGY STAR Partner, Hewlett-
Packard Company has determined the products marked with the ENERGY STAR Logo are ENERGY
ENWW ENERGY STAR 11
STAR qualified as per the applicable ENERGY STAR guidelines for energy efficiency. The following logo will appear on all ENERGY STAR qualified computers:
Figure 1-7 ENERGY STAR logo
The ENERGY STAR Computers Program was created by the EPA to promote energy efficiency and reduce air pollution through more energy-efficient equipment in homes, offices, and factories. One way products achieve this is by reducing power consumption when not being used through the Microsoft
Windows ® Power Management feature.
The Power Management feature allows the computer to enter into a low-power or “sleep” mode after a period of user inactivity. When used with an external ENERGY STAR compliant monitor, this feature will also support similar power management features of the monitor. To take advantage of this energy savings:
● The Power Management feature has been preset to power down the computer after 30 minutes of user inactivity.
● The Power Management feature has been preset to power down the monitor after 15 minutes of user inactivity.
Both the computer and monitor can be woken from “sleep” mode through user interaction with any of the computer’s input devices (for example; mouse, keyboard, and others). When configured with Wake
On LAN (WOL) enabled, the computer can also be awoken by a network signal.
More information on the energy and financial savings potential of the Power Management Feature can be found at the EPA’s ENERGY STAR Power Management website: http://www.energystar.gov/ powermanagement .
More information on the ENERGY STAR program and its environmental benefits is available by visiting the EPA ENERGY STAR Web site: http://www.energystar.gov
.
CAUTION: Using the Energy Save Monitor feature with non–ENERGY STAR compliant monitors may cause video distortion when the Energy Save timeout occurs.
NOTE: ENERGY STAR is not supported on Linux workstations.
If you must restore the operating system, reset the ENERGY STAR settings (if applicable) after the restore.
Using the ENERGY STAR Save Monitor feature with non-ENERGY STAR-compliant monitors might cause video distortion when the Energy Save timeout occurs.
NOTE: Not all configurations of the HP xw4550 Workstation are Energy Star compliant. For information on configurations of this workstation that are Energy Star compliant, contact you HP sales representative.
To verify the factory default power settings for your product, select Start>Control Panel and doubleclick Power Options.

Configuring Microsoft Windows XP Professional software
This section describes how to configure the Windows XP software.
Configuring the software
The operating system is configured when you first apply power to the system. This process takes approximately 5 to 10 minutes. Carefully follow the instructions on the screen to complete the configuration.
CAUTION: After the automatic configuration has begun, do not power off your workstation until this process completes. Powering off your workstation during the configuration process might damage the software that runs the system.
For complete operating system installation and configuration instructions, see the operating system documentation provided with your workstation. Additional information is available in the online help tool after you successfully configure the operating system.
18 Chapter 2 Configuring and restoring the operating system ENWW
Selecting a language
At the first boot of the factory preinstalled operating system, you might be prompted to select a language for the operating system. After selecting the language, read and follow the instructions on the screen to complete the configuration of the operating system. This process might take quite a while, depending on the system hardware configuration and the language choice. During the process, do not power off your workstation unless you are directed to do so.
NOTE: After you have selected a language during initial boot of the operating system, the language will be locked-in on the hard drive. If the system is restored with HP Backup and Recovery, only the previously selected language can be installed. If using RestorePlus! DVDs, the RestorePlus! DVD checks for the language stored on the hard drive and restores only the original preinstalled language.
If a new hard drive is installed or no language is found on the disk, the RestorePlus! DVD installs any language requested.
Creating recovery disks
When a new operating system is installed, you are prompted to create recovery disks. Refer to
Restoring the Windows XP Professional operating system on page 19
for details on the HP Backup and Recovery process.
Installing or upgrading device drivers
Required drivers must be installed after you configure the operating system, and before you install their respective hardware devices. In addition, for optimum performance, your operating system must have the most recent updates, patches, and software fixes. Access the following resources for driver and software updates:
● See the Microsoft site to obtain updates for your operating system, including current patches and software fixes.
● Device drivers are provided on a CD supplied with the peripheral device.
● Some peripheral device drivers developed for Windows XP or Vista might not be shipped with your workstation. To locate the current device drivers, see: http://www.hp.com/support/ workstation_swdrivers .
● For documentation on installing drivers and workstation operation, see: http://www.hp.com/ support/workstation_manuals .
Restoring the Windows XP Professional operating system
Your workstation has several methods to restore your Windows XP operating system to a near-factory state, or to the state of the system at a predefined snapshot in time. Your system has a recovery partition on the system hard drive that contains software and data required for the restore process as described in the following sections.
The RestorePlus! process
The Windows operating system and device drivers (for devices shipped with the system) are reinstalled using this process. Some application software may not be restored using the RestorePlus! process. In this case you must install the application software from the appropriate application CD. The RestorePlus!
process can be executed from CD or from the recovery partition contained on your system hard drive.
CAUTION: Back up your data before you attempt any operating system restore. All data on the
Windows partition will be deleted when you restore using the RestorePlus! process. However, the recovery partition on the system drive and other partitions should not be affected.
ENWW Setting up Microsoft Windows XP Professional software 19
Creating a RestorePlus! CD
You can create a set of the CDs from your system if you have a CD writer. When you first boot your system, you will be prompted to make CDs for RestorePlus!, the Windows operating system, and a supplemental HP Backup and Recovery Manager CD. (There may be additional CDs you can create depending on the options you purchased.) You also have the option to move images of the CDs to another location, such as a network share, to be written to CD at a later time or from another system.
Restoring from RestorePlus! CDs
The RestorePlus! process can be started by powering up from the RestorePlus! CD.
Restoring from RestorePlus! on the Recovery Partition
Follow these steps to start the RestorePlus! process from the Emergency Recovery menu:
1.
Boot the workstation.
2.

HP Backup and Recovery Manager restore points
HP Backup and Recovery Manager is preinstalled on your workstation. This software allows you to backup and restore your system and data. You will be prompted to make RestorePlus! CDs at the first boot of the system. An Initial Restore Point (IRP) will be created automatically. This restore point is a complete snapshot of the system partition at the time the IRP was created. The IRP is stored in the recovery partition on the system hard drive, but you can also write the IRP to CDs, DVDs, or copy it to another location. The restore point can be used to return the system partition back to the state the system was when captured.
Restoring from the HP Backup and Recovery Manager restore point CD or
DVDs
The HP Backup and Recovery Manager (HPBR) restore point can be written to CD or DVDs and used to restore the system. Typically you would used the CD/DVD set if the hard drive has been replaced or all partitions have been corrupted. Boot the system from the HPBR restore point CD/DVD and follow the online instructions.
Restoring from the HP Backup and Recovery Manager restore point on the
Recovery Partition
The HP Backup and Recovery Manager (HPBR) Initial Restore Point is stored in the system recovery partition and can be restored using the Emergency Recovery menu. Boot your system and press the

Workstation management
HP Client Management Solutions are available for download from http://www.hp.com/go/easydeploy .
They provide standards-based solutions for managing and controlling workstations in a networked environment. This section summarizes the capabilities and features of the key components of workstation management:
● Initial configuration and deployment
● Remote system installation
● Updating and managing software
● ROM flash
● Asset tracking and security
● Fault notification and recovery
NOTE: Support for specific features described in this guide might vary by model or software version.
Initial configuration and deployment
The workstation comes with a preinstalled system software image. After a brief software unbundling process, the workstation is ready to use.
You might prefer to replace the preinstalled software image with a customized set of system and application software. Several methods are available for deploying a customized software image, including:
● Installing additional software applications after unbundling the preinstalled software image
● Using a disk cloning process to copy the contents from one hard drive to another
The best deployment method depends on your information technology environment and processes. The
PC Deployment section of the HP Lifecycle Solutions Web site ( http://whp-sp-orig.extweb.hp.com/ country/us/en/solutions.html
) provides information to help you select the best deployment method.
The Restore Plus! CD, ROM-based setup, and ACPI hardware provide further assistance with recovery of system software, configuration management and troubleshooting, and power management.
Remote system installation
Remote system installation enables you to start and set up your system using the software and configuration information located on a network server. This feature is usually used as a system setup and configuration tool and can be used for the following tasks:

ROM Flash
The workstation comes with a programmable flash ROM. By establishing a setup password in the
Computer Setup (F10) Utility, you can protect the ROM from being unintentionally updated or overwritten. This is important to ensure the operating integrity of the workstation. To upgrade the ROM, download the latest SoftPaq images from http://www.hp.com/support/workstation_swdrivers .
NOTE: For maximum ROM protection, be sure to establish a setup password. The setup password prevents unauthorized ROM upgrades. System Software Manager enables you to set the setup password on one or more PCs simultaneously. For more information, see: http://www.hp.com/go/ssm .
Remote ROM Flash
Remote ROM Flash allows the system administrator to safely upgrade the ROM on remote HP workstations directly from the centralized network management console, resulting in a consistent deployment of and greater control over HP PC ROM images over the network. It also results in greater productivity and lower total cost of ownership.
The workstation must be powered on, or turned on through Remote Wakeup, to use Remote ROM Flash.
For more information on Remote ROM Flash, see the HP Client Manager Software or System Software
Manager sections at http://www.hp.com/go/ssm .
HPQFlash
The HPQFlash utility is used to locally update or restore the system ROM on individual PCs through a
Windows operating system.
For more information on HPQFlash, see: http://www.hp.com/go/ssm and enter the name of the workstation when prompted.
The FailSafe Boot Block ROM
The FailSafe Boot Block ROM is a flash-protected section of the workstation ROM that checks for a valid system ROM flash image whenever power is applied to the workstation. This protected section of
ROM allows the workstation to recover following an unlikely ROM flash failure (such that as caused by a workstation power loss) during a ROM upgrade.
36 Chapter 3 System management ENWW
When power is applied to the workstation, the FailSafe Boot Block ROM performs a validation of the system ROM, and:
● If the system ROM is valid, the workstation starts normally.
● If the system ROM fails the validation, the FailSafe Boot Block ROM provides enough support to start the workstation from a BIOS CD or USB storage media image created from a SoftPaq. To accomplish this recovery, the CD or USB media BIOS image programs the system ROM with a valid flash image.
When power is applied to the workstation and the FailSafe Boot Block validation detects an invalid system ROM image, the workstation power LED blinks red eight times with a simultaneous audible beep.
The workstation then looks for CD or USB media that contains a valid flash image. If no valid recovery image is found, a Boot Block recovery mode message to that effect is sent to the display. If a valid recovery media and flash image are found, the workstation flashes the system ROM with the valid image and a message to that effect is also sent to the display.
Preparing for validation failure recovery—In preparation for workstation system recovery, use the
BIOS CD media file in the SoftPaq to create a BIOS image CD as a recovery backup. You can also use
USB media such as an HP DriveKey as the BIOS image recovery media.
To create a BIOS image for recovery backup, see: http://www.hp.com/support/workstation_swdrivers
Recovering from a boot block validation failure—To recover the system ROM after it enters Boot
Block recovery mode:
1.
Remove all diskette and CD media from workstation drives.
2.
Insert a BIOS image recovery CD or USB storage media (such as an HP DriveKey) into the appropriate drive or connector.
3.
Power off, then power on the workstation.
If no BIOS image CD or USB media is found after the simultaneous eight red LED flashs and beeps, you are prompted to insert one and to restart the workstation. When a valid recovery image is found, the system ROM will flash that image.
NOTE: During system ROM recovery, the system ROM will flash without asking for a setup or power on password. However, following a successful recovery flash and workstation reboot, previously set passwords will remain active and are required.
4.
Remove the recovery CD or USB media and power off the system.
5.
Restart the workstation and resume normal operation.
Asset tracking and security
Asset tracking features incorporated into the workstation provide key asset tracking data that can be managed using HP Systems Insight Manager, HP Client Manager Software, or other system management applications. Seamless, automatic integration between asset tracking features and these products enables you to choose the management tool that is best suited to the environment and to leverage the investment in existing tools.
HP also offers several solutions for controlling access to valuable components and information.
ProtectTools Embedded Security, if installed, prevents unauthorized access to data and checks system integrity and authenticates third-party users attempting system access. Security features such as
ProtectTools and the optional Hood Sensor (Smart Cover Sensor) help prevent unauthorized access to your data and to the internal components of the workstation. By disabling serial or USB ports or by disabling removable media boot capability, you can protect valuable data assets. Memory Change and
ENWW Workstation management 37
Hood Sensor (Smart Cover Sensor) alerts can be automatically forwarded to system management applications to deliver proactive notification of tampering with a workstation’s internal components.
NOTE: ProtectTools, the Hood Sensor (Smart Cover Sensor), and the Hood Lock (Smart Cover Lock) are available as options on select systems.
Use the following utilities to manage security settings on the HP workstation:
● Locally, using the Computer Setup (F10) Utility.
● Remotely, using HP Client Manager Software or System Software Manager. This software enables the secure, consistent deployment and control of security settings from a simple command line utility.

Password security
The power-on password prevents unauthorized use of the workstation by requiring entry of a password to access applications or data each time the workstation is powered on or restarted. The setup password specifically prevents unauthorized access to the Computer Setup (F10) Utility and can also be used as an override to the power-on password. That is, when prompted for the power-on password, entering the setup password instead will enable access to the workstation.
You can establish a network-wide setup password to enable the system administrator to log in to all network systems to perform maintenance without having to know the power-on password.
NOTE: System Software Manager and HP Client Manager Software enable remote management of
Setup Passwords and other BIOS settings in a networked environment. For more information, see: http://www.hp.com/go/easydeploy .

Clearing passwords
If you forget your password, you cannot access the workstation. Refer to the section on resetting the password jumper for instructions on clearing passwords.
The DriveLock security feature
CAUTION: The DriveLock security feature can render a hard drive permanently inaccessible if the master password is lost or forgotten. No method exists to recover the password or access the data.
DriveLock uses an industry-standard security feature that prevents unauthorized access to the data on an ATA hard drive. DriveLock has been implemented as an extension to the Computer Setup (F10)
Utility functions. It is only available when hard drives that support the ATA security command set are detected. On HP workstations, it is not available when the SATA emulation mode is RAID+AHCI or
RAID.
DriveLock is intended for HP customers for whom data security is a paramount concern. For such customers, the cost of a hard drive and the loss of the data stored on it is inconsequential when compared to the damage that could result from unauthorized access to its contents.
In order to balance this level of security with the practical need to address the issue of a forgotten password, the HP implementation of DriveLock employs a two-password security scheme. One password is intended to be set and used by a system administrator, while the other is typically set and used by the end-user. There is no "back door" that can be used to unlock the drive if both passwords are lost. Therefore, DriveLock is most safely used when the data contained on the hard drive is replicated on a corporate information system or is regularly backed up. In the event that both DriveLock passwords
ENWW Workstation management 41
are lost, the hard drive is rendered unusable. For users who do not fit the previously defined customer profile, this may be an unacceptable risk. For users who do fit this profile, it may be a tolerable risk, given the nature of the data stored on the hard drive.
DriveLock applications
The most practical use of the DriveLock security feature is in a corporate environment. The system administrator would be responsible for configuring the hard drive, which involves setting the DriveLock master password and a temporary user password. In the event that the user forgets the user password or the equipment is passed on to another employee, the master password can always be used to reset the user password and regain access to the hard drive.
HP recommends that corporate system administrators who choose to enable DriveLock also establish a corporate policy for setting and maintaining master passwords. This should be done to prevent a situation where an employee intentionally or unintentionally sets both DriveLock passwords before leaving the company. In such a scenario, the hard drive is rendered unusable and requires replacement.
Likewise, by not setting a master password, system administrators might find themselves locked out of a hard drive and unable to perform routine checks for unauthorized software, other asset control functions, and support.
For users with less stringent security requirements, HP does not recommend enabling DriveLock. Users in this category include personal users, or users who do not maintain sensitive data on their hard drives as a common practice. For these users, the potential loss of a hard drive resulting from forgetting both passwords is much greater than the value of the data DriveLock has been designed to protect.
Access to the Computer Setup (F10) Utility and DriveLock can be restricted through the setup password.
By specifying a setup password and not giving it to end users, system administrators are able to restrict users from enabling DriveLock.
Using DriveLock
When one or more hard drives that support the ATA security command set are detected, the DriveLock option appears under the Security menu in the Computer Setup (F10) Utility. You are presented with options to set the master password and to enable DriveLock. A user password must be provided to enable DriveLock. Since the initial configuration of DriveLock is typically performed by a system administrator, a master password should be set first. HP encourages system administrators to set a master password whether they plan to enable DriveLock or not. This gives the administrator the ability to modify DriveLock settings if the drive is locked in the future. Once the master password is set, the system administrator might enable DriveLock or choose to leave it disabled.
If a locked hard drive is present, POST requires a password to unlock the device. If a power-on password is set and it matches the device’s user password, POST does not prompt the user to re-enter the password. Otherwise, the user is prompted to enter a DriveLock password. For a cold-boot, use the master or user password. For a warm-boot, you must enter the same password used to unlock the drive during the preceding cold-boot. Users are given two attempts to enter a correct password. During coldboot, if neither attempt succeeds, POST continues but the drive remains inaccessible. During a warmboot or restart from Windows, if neither attempt succeeds, POST halts and the user is instructed to cycle power.
To enable and set the DriveLock user password:
1.
Power on or restart the workstation.
2.
As soon as the workstation is powered on, press and hold the F10 key until you enter the Computer
Setup (F10) Utility. Press Enter to bypass the title screen, if necessary.
NOTE: If you do not press the F10 key at the appropriate time, you must restart the workstation, and then press and hold the F10 key again to access the utility.

3.
Select Security>DriveLock Security.
4.
For each DriveLock-capable drive, select a drive by pressing the F10 key to accept.
5.
Under Enable/Disable DriveLock options, select Enable, and then press the F10 key to enable
DriveLock for a particular drive.
CAUTION: Forgetting the DriveLock password renders the drive unusable.
6.
Enter a new user password, and then press the F10 key to accept. This password can contain anywhere from one to 32 characters.
7.
Enter the password again in the Enter New Password Again field. If you forget this password, the drive is rendered permanently disabled.
8.
Select File>Save Changes and Exit, and then press the F10 key. After you press the F10 key, the system performs a cold-boot before invoking the DriveLock function.
NOTE: This process can also be used to set the DriveLock master password by selecting Master in
Step 5.
When the workstation starts, you are prompted to enter the DriveLock password for each DriveLockcapable drive for which you have previously set a password. You are given two attempts to enter the password correctly. If the password is not entered correctly, the workstation attempts to boot anyway.
However, the boot process most likely fails because data from a locked drive cannot be accessed.
You can configure your workstation to boot either with or without DriveLock enabled for the boot drive as follows:
● In a single drive workstation, if the drive is DriveLock enabled, the workstation might not be able to boot to the operating system, and might try to boot from the network or from another storage device instead (depending on the boot ordering options). Regardless of the outcome of the boot attempts, the drive-locked drive remains inaccessible without the DriveLock password.
● In a two-drive workstation that has a boot drive and a data drive, you can apply the DriveLock feature to the data drive only. In this case, the workstation can always boot without the DriveLock password, but the data drive is accessible only when the DriveLock password is entered.
Cold-boots require that you enter DriveLock passwords. However, DriveLock passwords are also required for warm-boots. For example, if you boot to DOS and enter Ctrl-Alt-Del , you must enter the
DriveLock password before the workstation completes the next boot cycle. This warm-boot behavior is consistent with the DriveLock feature.
Hood sensor option (smart cover sensor)
The optional hood sensor is a combination of hardware and software technology that can alert you when the workstation side access panel has been removed if the sensor has been properly configured in the
Computer Setup (F10) Utility. There are three levels of protection, as described in the following table.

Prevents removal of the access panel and all internal components including optical and diskette drives.
This lock eliminates the need for a physical key by enabling password-protected locking and locking by a local or a remote user.
Hood sensor (Smart cover sensor) (optional)
This sensor is set in the Computer Setup (F10) Utility. You can set this to notify a user if the access panel has been removed.
Fault notification and recovery
Fault notification and recovery features combine innovative hardware and software technology to prevent the loss of critical data and minimize unplanned downtime
If the workstation is connected to a network managed by HP Client Manager Software, the computer sends a fault notice to the network management application. With HP Client Manager Software, you can also remotely schedule diagnostics to automatically run on all managed PCs and create a summary report of failed tests.
ENWW Workstation management 45
Drive Protection System
The Drive Protection System (DPS) is a diagnostic tool built into the hard drives that is installed in select
HP workstations. the DPS is designed to help diagnose problems that might result in unwarranted hard drive replacement.
When HP workstations are built, each installed hard drive is tested using the DPS, and a permanent record of key information is written onto the drive. Each time the DPS is run, test results are written to the hard drive. The service provider can use this information to help diagnose conditions that caused you to run the DPS software.
ECC fault prediction and prefailure warranty
When the workstation encounters an excessive number of error checking and correcting (ECC) memory errors, the workstation displays a Local Alert message. This message contains detailed information about the errant memory module, enabling you to take action before you experience non-correctable memory errors. The Prefailure Warranty for ECC memory modules enables you to replace these modules, free of charge, before the modules actually fail. ECC memory modules are optional on selected
HP workstations.
Thermal sensor
There are multiple sensors on your workstation:
● One for the processor
● One for the system board
● Some hard drives
The processor thermal sensor monitors the processor core temperature, while the board thermal sensor monitors the internal temperature of the workstation. These sensors control the speed of the workstation cooling fans as the processor and internal workstation temperatures increase and decrease.
The cooling system is designed to provide maximum thermal dissipation for a fully configured workstation, which ensures that the processor and all system components do not exceed safe operating temperatures. If the maximum force of the cooling fans cannot adequately cool the processor, the processor clock automatically begins to slow. If the temperature remains above limits even with reduced processor clock speed, the system eventually shuts down.
Dual-State Power Button
With ACPI enabled, the power button can function either as an on/off switch or as a button. The feature does not completely turn off power, but instead causes the workstation to enter a low-power standby state. This allows you to power down without closing applications and to return to the same operational state without any data loss.
To change the power button configuration:
1.
Select Start, and select Control Panel>Power Options.
2.
In Power Options Properties, select the Advanced tab.
3.
In the Power Button section, select Hibernate. (Hibernate must be enabled in the Hibernate tab.)
After configuring the power button to function as a button, press the power button to put the system in a very low power state. Press the button again to bring the system out of the very low power state to full power status. To completely turn off all power to the system, press and hold the power button for four seconds.
46 Chapter 3 System management ENWW
CAUTION: Do not use the power button to power off the workstation unless the system is not responding; turning off the power without operating system interaction could cause damage to or loss of data on the hard drive.

Service considerations
The following sections discuss service considerations that should be reviewed and practiced before removing and replacing any system components.
WARNING!
When lifting or moving the workstation, do not use the front bezel as a handle or lifting point. Lifting the workstation from the front bezel or lifting it incorrectly can cause the unit to fall and harm you and damage the workstation. To properly and safely lift the workstation, lift it from the bottom of the unit.
Cautions, warnings, and safety precautions
For your safety, review the cautions, warnings, and safety precautions before accessing the workstation components. Also, review the Safety and Regulatory Guide that came with your workstation for more information.
Electrostatic discharge information
A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device exposed to electrostatic discharge (ESD) might not appear to be affected at all and can function normally for a while, but it has been degraded in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge contains enough power to alter device parameters or melt silicon junctions.
Generating static electricity
The following table shows that different activities generate different amounts of static electricity. Static electricity increases as humidity decreases.

Processor heatsink
NOTE: The following illustrated processor heatsink is typical of what you might have in your workstation. Be aware that different variations of the processor heatsinks exist, but the overall procedures listed are sufficient to assist you in removing the processor heatsink.
To remove the processor heatsink:
1.
Apply power to the workstation for a minimum of five minutes before proceeding to the next step.
Heat generated by this process will cause the thermal grease between the heatsink and processor surfaces to become less viscous, thereby allowing the heatsink to be separated from the processor with minimum force.
2.
Shut down and disconnect power from the workstation, and remove the side access panel.
3.
Loosen the four processor screws slowly and evenly, loosening them two at a time as a diagonally opposing pair.
NOTE: Do not fully loosen one screw, and then move on to the next. Loosen all of the screws a little at a time, being sure the processor remains level to the system board.
Figure 4-49 Identifying proper screw loosening sequence
4.
Disconnect the heatsink fan cable (1) from the system board.
5.
Gently twist the heatsink unit to break the thermal grease binding.
92 Chapter 4 Removal and replacement procedures ENWW
6.
Lift the heatsink (2) from the processor.
Figure 4-50 Removing the processor heatsink from the system board
ENWW
7.
Use alcohol and a soft cloth to clean all of the thermal interface residue from the heatsink and processor.
CAUTION: Allow the alcohol on the processor and heatsink to dry completely.
To replace the processor heatsink:
1.
Disconnect power from the system (
Predisassembly procedures on page 55 ). Remove the side
chassis access panel (
Side access panel on page 59 ).
2.
Check for proper processor seating in the socket by carefully trying to lift the processor out of the socket with your fingers. A properly seated processor does not lift out of the socket.
3.
If reusing the original heatsink, apply thermal grease to the center of the processor top surface. If using a new processor heatsink, do not apply thermal grease to the processor; the a new heatsink will have grease already applied to the heatsink surface. In this case, discard the thermal grease protective liner from the bottom of the new heatsink before installing.
NOTE: Do not touch the exposed thermal grease when handling the processor heatsink.
4.
Lower the processor heatsink onto the system board over the processor.
5.
Carefully tighten the four screws a little at a time; do not fully tighten one screw and move onto the next. Be sure the processor remains level and be sure you do not overtighten the screws. If you have a torque-limited driver available, tighten the screws to 6 in.-lbs.
CAUTION: Do not overtighten the screws. If you overtighten the screws, you risk stripping the threads in the system board tray.

HP Insight Diagnostics Offline Edition
The HP Insight Diagnostics utility enables you to perform diagnostic testing and to view critical computer hardware and software configuration information from various sources.
Key features and benefits
The HP Insight Diagnostics utility simplifies the process of effectively identifying, diagnosing, and isolating the hardware issues, and helps provide a higher level system availability. In addition to robust management tools, it also provides service tools can be invaluable in quickly resolving system problems.
You can use the HP Insight Diagnostics tool to streamline the service process and help resolve problems quickly by providing the detailed information required at the time you place a service call. The primary information requirement (the information that provides the greatest insight into potential system issues) is the configuration of the system. Typical uses of the HP Insight Diagnostics tool are:
● Testing and diagnosing apparent hardware failures.
● Documenting system configurations for upgrade planning, standardization, inventory tracking, disaster recovery, and maintenance.
● Sending configuration information to another location for more in-depth analysis.
Theory of operation
Insight Diagnostics Offline Edition operates in offline mode only. The operating system is not running and software information from the system is not available to the diagnostics. The utility Offline Survey, however, is available to display the current system configuration.
The Insight Diagnostics Test feature provides the capability to test the functionality of all the major hardware components in the system. The Test feature is designed to be flexible to enable you to customize test selections by providing different modes and types of testing. Test modes include the following:
● Quick Test provides a predetermined script where a sample of each hardware component is exercised and requires no user intervention.
● Complete Test provides a predetermined script during which each hardware component is fully tested. You can select Interactive or Unattended tests. This will change the devices tested during the Complete Test. There are more tests available in the interactive mode, but these require user intervention.
● Custom Test provides the most flexibility in controlling the testing of a system. The Custom Test mode enables you to specifically select which devices, tests, and test parameters are run. You can select tests that do not require any user interaction through the Interactive and Unattended tests modes.

7 Configuring password security and resetting CMOS
Preparing to configure passwords
This workstation supports the following security password features, which can be established through the Computer Setup (F10) Utility menu:
● Setup password
● Power-on password
When you establish a setup password, only the power-on password is required to access the Computer
Setup (F10) Utility and any other information on the workstation. When you establish both passwords, only the setup password will give you access to the Computer Setup (F10) Utility.
When both passwords are set, the setup password can also be used in place of the power-on password as an override to log in to the workstation, which is a useful feature for a network administrator.
If you forget the password for the computer, two methods are available for clearing that password so you can gain access to the information on the workstation:
● Reset the password jumper
● Use the Clear CMOS spring-loaded slider switch.
CAUTION: Pushing the CMOS switch to detente resets CMOS values to factory defaults and erases any customized information, including passwords, asset numbers, and special settings. It is important to back up the workstation CMOS settings before resetting them in case they are needed later. To back up the CMOS settings, use the Computer Setup (F10) Utility and run the Save to Diskette option from the File menu.
ENWW Preparing to configure passwords 131
Resetting the password jumper
To disable the power-on or setup password features and clear the power-on and setup passwords:
1.
Shut down the operating system, and power off the workstation and any external devices.
Disconnect the power cord of the workstation and any external devices from the power outlets.
2.
Disconnect the keyboard, monitor, and any other external devices that are connected to the workstation.
WARNING!
To reduce the risk of personal injury from electrical shock and hot surfaces, be sure to disconnect the power cord from the line voltage power outlet and allow the internal system components to cool before touching.
CAUTION: When the workstation is plugged in, the power supply always has voltage applied to the system board even when the workstation is turned off. Failure to disconnect the power cord can result in damage to the system.
CAUTION: Static electricity can damage the electronic components of the workstation or optional equipment. Before beginning these procedures, be sure that you are discharged of static electricity by briefly touching a grounded metal object.
3.
Remove the access panel.
4.
Locate the password header and jumper. The password header is E49 on the system board.
NOTE: The password jumper is green so that it can be easily identified. For assistance locating the password jumper and other system board components, see the service label located on the inside of the workstation access panel.
5.
Remove the jumper from either pin 1 or 2. Place the jumper on pins 1 and 2 (connecting both pins together).
6.
Replace the access panel.
7.
Reconnect the external equipment.
8.
Plug in and power on the workstation. Allow the operating system to start. This process clears the current passwords and disables the password features.
9.
To establish new passwords, repeat steps 1 through 4, replace the password jumper on either pin
1 or pin 2 (but not both), and repeat steps 6 through 8. Establish the new passwords in the Computer
Setup (F10) Utility.
Clearing and Resetting the CMOS
The CMOS of the workstation stores password information and information about the workstation configuration. This section describes the steps to successfully clear and reset the CMOS.
132 Chapter 7 Configuring password security and resetting CMOS ENWW
Using the CMOS switch
1.
Shut down the operating system, and power off the workstation and any external devices.
Disconnect the workstation power cord and any external devices from the power outlets.
2.
Disconnect the keyboard, monitor, and any other external devices that are connected to the workstation.
WARNING!
To reduce the risk of personal injury from electrical shock and hot surfaces, be sure to disconnect the power cord from the wall outlet and allow the internal system components to cool before touching.
CAUTION: When the workstation is plugged in to a line voltage source, voltage is continuously applied the system board even when the unit is powered off. Failure to disconnect the power cord can result in damage to the system.
CAUTION: Static electricity can damage the electronic components of the workstation or optional equipment. Before beginning these procedures, be sure that you are discharged of static electricity by briefly touching a grounded metal object.
3.
Remove the access panel.
CAUTION: It is important to back up the workstation CMOS settings before resetting them in case they are needed later. Activating the CMOS switch resets CMOS values to factory defaults and erases any customized information, including passwords, asset numbers, and special settings. To back up the CMOS settings, use the Computer Setup (F10) Utility and run the Save to Diskette option from the File menu.
4.
Locate, press, and hold the CMOS switch in the detente position for five seconds.
NOTE: Ensure that the AC power cord is disconnected from the power outlet. The CMOS switch does not clear CMOS if the power cord is connected.
NOTE: To locate the CMOS switch and other system board components, see the service label located on the inside of the workstation access panel or the
System board components on page 56
section of this guide.
5.
Replace the access panel.
6.
Reconnect any external devices.
7.
Plug in and power on the workstation.
The workstation will power up for 3-to-5 seconds, then power off.
NOTE: You must reset the workstation passwords and any special configurations, along with the system date and time.
ENWW Clearing and Resetting the CMOS 133
Using the Computer Setup (F10) Utility to reset CMOS
1.
To reset CMOS using the Computer Setup (F10) Utility, access the Computer Setup (F10) Utility menu. When the Computer Setup message appears in the lower-right corner of the screen, press the F10 key. Press Enter to bypass the title screen, if necessary.
NOTE: If you do not press the F10 key while the message is displayed, the workstation must be powered off, then on again, to access the utility.
2.
From the Computer Setup (F10) Utility menu, select File>Set Defaults and Exit. This restores the soft settings that include boot sequence order and other factory settings. It does not, however, force hardware rediscovery.
NOTE: You must reset the workstation passwords and any special configurations, along with the system date and time.

General cleaning safety precautions
● Never use solvents or flammable solutions to clean the workstation.
● Never immerse any component in water or cleaning solutions; apply any liquids to a clean cloth and then use the cloth on the component.
● Always unplug the workstation before cleaning the keyboard, mouse, or air vents.
● Always disconnect the keyboard before cleaning it.
● Wear safety glasses equipped with side shields when cleaning the keyboard.
Cleaning the workstation case
● Follow the safety precautions presented in before cleaning the workstation.
● To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.
● For stronger stains, use a mild dish-washing liquid diluted with water. Rinse well by wiping it with a cloth or swab dampened with clear water.
● For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed because the alcohol will evaporate quickly and not leave a residue.
● After cleaning, always wipe the unit with a clean, lint-free cloth.
● Occasionally clean the air vents on the workstation. Lint and other foreign matter can block the vents and limit the airflow.
Cleaning the keyboard
CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the keys.
●
Follow the safety precautions presented in Service considerations on page 50 before cleaning the
keyboard.
● Visible debris underneath or between the keys can be removed by vacuuming or shaking.
● Canned, pressurized air can be used to clean debris from under the keys. Use caution because too much air pressure can dislodge lubricants applied under the wide keys.
● If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronic supply outlets.
CAUTION: Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are improperly removed or installed, the keyboard might not function properly.
ENWW General cleaning safety precautions 145
● Clean under a key with a swab moistened with isopropyl alcohol and squeezed out. Be careful not to wipe away lubricants necessary for proper key functions. Allow the parts to air dry before reassembly.
● Use tweezers to remove any fibers or dirt in confined areas.
Cleaning the monitor
●
Follow the safety precautions presented in Service considerations on page 50 before cleaning the
keyboard.
● To clean the monitor, wipe the monitor screen with a towelette designed for cleaning monitors or a clean cloth moistened with water.
CAUTION: Do not use sprays or aerosols directly on the screen—the liquid might seep into the housing and damage a component.
Never use solvents or flammable liquids on the monitor because display or housing damage may result.
Cleaning the mouse
1.
Follow the safety precautions presented in Service considerations on page 50 before cleaning the
mouse.
2.
Remove the mouse ball from the housing by removing the retaining plate.
3.
Clean the mouse ball.
4.
Pull out any debris from the ball socket, and wipe the ball with a clean, dry cloth.
5.
Reassemble the mouse.
