Ensuring proper ventilation
Proper ventilation for the system is important for workstation operation. Follow these guidelines:
●Operate the workstation on a sturdy, level surface.
●Provide at least 15.24 cm (6 inches) of clearance at the front and back of the workstation.
(Workstation models vary.)
●Ensure that the ambient air temperature falls within the environmental specifications listed in this
document.
NOTE: The ambient upper limit of 35°C (95°F) is only good up to 1524 m (5000 ft) elevation.
There is a 1°C (33.8°F) per 304.8 m (1000 ft) derating above 1524 m (5000 ft). So, at 3,048 m
(10,000 ft), the upper ambient air temperature limit is 30°C (86°F).
●For cabinet installation, ensure adequate cabinet ventilation and ensure that the ambient
temperature within the cabinet does not exceed specified limits.
●Never restrict the incoming or outgoing airflow of the workstation by blocking any vents or air
intakes, as shown in the following figure.
Ensuring proper ventilation 37

Hyper-Threading Technology (HTT)
This computer supports HTT, an Intel-proprietary technology that improves processor performance
through parallelization of computations (doing multiple tasks at once).
The operating system treats an HTT-enabled processor as two virtual processors, and shares the
workload between them when possible. This feature requires that the operating system support
multiple processors and be specifically optimized for HTT.
Use the Computer Setup (F10) Utility to enable HTT.
Go to http://www.hp.com/go/quickspecs to determine if your CPU supports HTT.
SATA Power Management
SATA Power Management enables or disables SATA bus and/or device power management.
Intel Turbo Boost Technology
The HP Z Workstation series supports Intel® Turbo Boost Technology.
This feature enables the CPU to run at a higher than normal rate. When all CPU cores are not
necessary for the workload, inactive cores are turned off and power is diverted to the active cores to
increase their performance.
Turbo Boost is enabled and disabled with the Computer Setup (F10) Utility.
Go to http://www.hp.com/go/quickspecs to determine if your CPU supports Turbo Boost.
HP Cool Tools (Windows 7 only)
HP workstations and computers running Windows® 7 include additional software tools. To access or
learn more about these tools that can enhance the computer experience:
1. Double-click the HP Cool Tools icon on the desktop.
2. To learn more about an HP Cool Tools application, click the Learn More link for the application.
3. To install or launch an application, select the and follow the on-screen instructions.
Power management and performance features 39
Non-Uniform Memory Access (NUMA)
Non-Uniform Memory Access (NUMA) is available on some Z series Workstations. NUMA can
improve memory bandwidth and latency for multi-process or multi-threaded applications or workloads.
Observed performance improvements depend on the operating system, customer workload, system
configuration, and the degree to which the applications used are designed to be NUMA-aware/
efficient.
NUMA requires that both processor sockets be populated. Installed memory should be balanced
between both processors for maximum performance.
NUMA is enabled if Memory Node Interleave is disabled in the system BIOS. To do this, press F10
during startup to enter Computer Setup (F10) Utility. Select Advanced > Chipset/Memory. Use the
arrow keys to set Memory Node Interleave to Disable. Press F10 to exit the menu, then select File >
Save Changes and Exit. NUMA is enabled when the system is restarted.
BIOS ROM
The BIOS ROM is a collection of machine language applications stored as firmware in ROM. It
includes functions such as Power on Self Test (POST), PCI device initialization, Plug and Play
support, power management, and the Computer Setup (F10) Utility.
Go to http://www.hp.com/go/quickspecs to review the latest BIOS ROM specifications.

HP SoftPaq Download Manager
HP SoftPaq Download Manager is a free, easy-to-use interface for locating and downloading software
updates for the HP client PC models in your environment. By specifying your models, operating
60 Chapter 2 System management
system, and language, you can quickly locate, sort, and select the softpaqs you need. For more
information, go to http://www.hp.com/go/sdm.
System Software Manager
System Software Manager (SSM) is a utility available on Windows—based computers that enables
you to update system-level software on multiple systems simultaneously. When executed on a PC
client system, SSM detects hardware and software versions and then updates the software from a
central repository, known as a
file store
. Driver versions supported by SSM are noted with a special
icon on the software, the driver download website, and on the Support Software CD.
To download the utility or to obtain more information about SSM, see http://www.hp.com/go/ssm.
ROM Flash
BIOS settings are stored on a programmable flash ROM. By establishing a setup password in
Computer Setup (F10) Utility, you can protect unauthorized users from modifying the BIOS settings.
This function is important to ensure the operating integrity of the computer.
To upgrade the BIOS, download the latest SoftPaq images from http://www.hp.com/support/
workstation_swdrivers.
Remote ROM Flash
Remote ROM Flash allows system administrators to safely upgrade the ROM on remote HP
computers from a centralized network management console, resulting in a consistent deployment of,
and greater control over, HP PC ROM images over the network.
To use Remote ROM Flash, the computer must be powered on, or turned on using Remote Wakeup.
For more information about Remote ROM Flash and HPQFlash, 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 PCs using a Windows
operating system. For more information about HPQFlash, see http://www.hp.com/go/ssm, and enter
the name of the computer.
FailSafe Boot Block
The FailSafe Boot Block enables BIOS recovery in the unlikely event of a ROM flash failure. For
example, if a power failure occurs during a ROM upgrade, the Boot Block uses a flash-protected
section of the ROM to verify a valid system ROM flash when power is restored to the computer.
If the system ROM is valid, the computer starts normally.
If the system ROM fails the validation check, the FailSafe Boot Block provides enough support to start
the computer from a BIOS image CD created from a SoftPaq. The BIOS image CD programs the
system ROM with a valid image.
When Boot Block detects an invalid system ROM, the computer power LED blinks red eight times and
the computer beeps eight times; then the computer pauses for two seconds. On some models, a Boot
Block recovery mode message appears.
In preparation for system recovery, use the BIOS CD media file in the SoftPaq to create a BIOS
image CD or USB key.
Desktop management 61
Recovering the computer from Boot Block Recovery mode
To recover the computer after it enters Boot Block recovery mode:
1. Remove any media such as USB keys or disks in the optical disk drives.
2. Insert a BIOS image CD into the DVD drive. You can also use USB media such as an HP
DriveKey.
3. Power off, then power on the computer.
If no BIOS image CD or USB media is found, you are prompted to insert one and restart the
computer.
If a setup password has been established, the Caps Lock light illuminates and you are prompted
for the password.
4. Enter the setup password.
If the computer starts from the boot media and successfully reprograms the ROM, three
keyboard lights illuminate and a rising-tone series of beeps signals successful recovery.
5. Remove the boot media and power off the computer.
6. Restart the computer.
Workstation security
This section provides information about providing system security through asset tracking, password
security, hard disk drive locking, and chassis locks.
62 Chapter 2 System management
Asset tracking
Asset tracking features provide asset tracking data that can be managed using HP Systems Insight
Manager (HP SIM), HP Console Management Controller (CMC), or other systems-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 investments in
existing tools.
HP also offers several solutions for controlling access to valuable components and information:
●HP ProtectTools Embedded Security prevents unauthorized access to data, checks system
integrity, and authenticates third-party users attempting system access.
●Security features such as ProtectTools and the Smart Cover Sensor (side access panel sensor)
help prevent unauthorized access to the data and to the internal components of the computer.
●By disabling parallel, serial, or USB ports, or by disabling removable-media boot capability, you
can protect valuable data assets.
●Memory Change and Side access panel sensor (Smart Cover Sensor) alerts can be forwarded
to system management applications to deliver proactive notification of tampering with a
computer’s internal components.
ProtectTools, the Smart Cover Sensor, and the side access panel solenoid lock (Hood Lock) are
available as options on select systems.

Desktop management 63
SATA hard disk drive security
HP computers include the HP DriveLock facility for SATA hard disk drives to prevent unauthorized
access to data.
WARNING! Enabling DriveLock can render a SATA hard disk drive permanently inaccessible if the
master password is lost or forgotten. No method exists to recover the password or access the data.
DriveLock has been implemented as an extension to Computer Setup (F10) functions. It is only
available when hard disk drives that support the ATA security command set are detected. On HP
computers, it is not available when the SATA emulation mode is RAID+AHCI or RAID.
DriveLock is for HP customers for whom data security is a paramount concern. For such customers,
the cost of a hard disk 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.
To balance this level of security with the 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 user.
No "back door" 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 disk drive is replicated on a corporate
information system or is regularly backed up.
If both DriveLock passwords are lost, the hard disk drive is rendered unusable. For users who do not
fit the previously defined customer profile, this might not be acceptable. For users who fit this profile,
it might be a tolerable risk, given the nature of the data stored on the hard disk drive.
64 Chapter 2 System management
DriveLock applications
The most practical use of DriveLock is in a corporate environment. The system administrator would
be responsible for configuring the hard disk drive, which involves setting the DriveLock master
password and a temporary user password. If you forget the user password or if the equipment is
passed on to another employee, the master password can be used to reset the user password and
regain access to the hard disk drive.
HP recommends that corporate system administrators who enable DriveLock also establish a
corporate policy for setting and maintaining master passwords. This should be done to prevent a
situation where an employee sets both DriveLock passwords before leaving the company. In such a
scenario, the hard disk drive is unusable and requires replacement. Likewise, by not setting a master
password, system administrators might find themselves locked out of a hard disk 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 disk drives as a common practice. For these users, the potential loss of a hard disk drive
resulting from forgetting both passwords is much greater than the value of the data DriveLock
protects.
Access to Computer Setup (F10) and DriveLock can be restricted through the setup password. By
specifying a setup password and not giving it to users, system administrators can restrict users from
enabling DriveLock.
Using DriveLock
When hard disk drives that support the ATA security command set are detected, DriveLock appears
under the Security menu in Computer Setup (F10) menu. You are presented with options to set the
master password and to enable DriveLock. You must provide a user password to enable DriveLock.
Because 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. After the master password is set, the system administrator can enable DriveLock
or leave it disabled.
If a locked hard disk 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 start, use the master or user password. For a warm start, enter the same password used to
unlock the drive during the preceding cold start.
Users have two attempts to enter a correct password. During cold start, if neither attempt succeeds,
POST continues but the drive remains inaccessible. During a warm-start or restart from Windows, if
neither attempt succeeds, POST halts and the user is instructed to cycle power.
Desktop management 65
Enabling DriveLock
To enable and set the DriveLock user password:
1. Power on or restart the computer.
2. As soon as the computer is powered on, repeatedly press the F10 key until you enter Computer
Setup (F10) Utility.
If you do not press F10 at the appropriate time, you must restart the computer, then repeatedly
press F10 again to access the utility.
3. Select Security > DriveLock Security.
4. For each DriveLock-capable drive, select a drive by pressing F10 to accept.
5. Under Enable/Disable DriveLock options, select Enable, and then press F10 to enable
DriveLock for a specific drive.
NOTE: To set the DriveLock master password, select Master.
CAUTION: If you forget the DriveLock password, the drive is unusable.
6. Enter a new user password (1 to 32 characters long), and then press F10 to accept.
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 Enter to accept the changes. After you
press Enter, the computer performs a cold start before invoking the DriveLock function.
When the computer starts, you are prompted to enter the DriveLock password for each
DriveLock-capable drive for which you have set a password. You have two attempts to enter the
password correctly. If the password is not entered correctly, the computer attempts to start
anyway. However, the boot process most likely fails because data from a locked drive cannot be
accessed.
In a single drive computer, if the drive has DriveLock enabled, the computer might not be able to
boot to the operating system, and might try to boot from the network or from another storage
device (depending on the boot ordering options). Regardless of the outcome of the start
attempts, the drive-locked drive remains inaccessible without the DriveLock password.
In a two-drive computer that has a boot drive and a data drive, you can apply the DriveLock
feature to the data drive only. In this case, the computer can always start, but the data drive is
accessible only when the DriveLock password is entered.
Cold starts require that you enter DriveLock passwords. However, DriveLock passwords are also
required for warm starts. For example, if you boot to DOS and press Ctrl+Alt+Del, you must
enter the DriveLock password before the computer completes the next start cycle. This warm-
start behavior is consistent with the DriveLock feature.
66 Chapter 2 System management
Password security
The power-on password prevents unauthorized use of the computer by requiring entry of a password
to access applications or data when the computer is powered on or restarted. The setup password
specifically prevents unauthorized access to Computer Setup (F10) Utility and can also be used as an
override to the power-on password. When prompted for the power-on password, entering the setup
password instead enables access to the computer.
You can establish a network-wide setup password to enable the system administrator to log in to all
network systems to perform maintenance without needing to know the power-on password.
Establishing a setup password using Computer Setup (F10) Utility
Establishing a setup password through Computer Setup (F10) Utility prevents reconfiguration of the
computer (through the use of Computer Setup (F10) Utility) until the password is entered.

If the computer is connected to a network that is managed by HP CMS, the computer sends a fault
notice to the network management application. With HP CMS, you can also remotely schedule
diagnostics to run on managed PCs and create a summary report of failed tests.
Drive Protection System
The Drive Protection System (DPS) is a diagnostic tool built into hard disk drives and is installed in
select HP computers. The DPS helps diagnose problems that might result in unwarranted hard disk
drive replacement.
When HP computers are built, each installed hard disk drive is tested using the DPS, and a
permanent record of key information is written onto each drive. Every time the DPS is run, test results
are written to the hard disk drive. The service provider can use this information to help diagnose
conditions that required you to run the DPS software.
ECC fault prediction
When the computer encounters an excessive number of error checking and correcting (ECC) memory
errors, it displays a local alert message. This message contains information about the errant DIMM,
enabling you to take action before you experience noncorrectable memory errors. ECC DIMMs are
standard on this computer.

Preventing ESD
equipment damage
Many electronic components are sensitive to ESD. Circuitry design and structure determine the
degree of sensitivity. The following packaging and grounding precautions are necessary to
prevent damage to electric components and accessories:
●Transport products in static-safe containers such as tubes, bags, or boxes, to avoid hand
contact.
●Protect electrostatic parts and assemblies with nonconductive or approved containers or
packaging.
●Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
●Place items on a grounded surface before removing them from containers.
Service considerations 75
●When handling or touching a sensitive component or assembly, ground yourself by touching
the chassis.
●Avoid contact with pins, leads, or circuitry.
●Place reusable electrostatic-sensitive parts from assemblies in protective packaging or
nonconductive foam.
Personal grounding
methods and
equipment
Use the following items to help prevent ESD damage:
●Wrist straps — These are flexible straps with a maximum of one megohm ± 10% resistance
in the ground cords. To provide a proper ground, wear the strap against bare skin. The
ground cord must be connected and fit snugly into the banana plug connector on the
grounding mat or computer.
●Heel straps, toe straps, and boot straps — These can be used at standing computers and
are compatible with most types of shoes or boots. On conductive floors or dissipative floor
mats, use them on both feet with a maximum of one megohm ± 10% resistance between the
operator and ground.

Product recycling 77
Cable management
Proper routing of the internal cables is critical to the operation of the workstation. Follow good cable
management practices when removing and installing components.
●Handle cables with care to avoid damage.
●Apply only the tension required to seat or unseat cables during insertion or removal from the
connector.
●When possible, handle cables by the connector or pull-strap.
●Route cables in such a way that they cannot be caught or snagged by parts being removed or
replaced.
●Keep cables away from direct contact with major heat sources, such as the heatsink. (Some air
flow guides have a cable guide that lets you route cables safely around the heatsink.)
●Do not jam cables on top of expansion cards or DIMMs. Circuit cards and DIMMs are not
designed to take excessive pressure.
●Keep cables clear of movable or rotating parts (such as the power supply and drive cage) to
prevent them from being cut or crimped when the component is lowered into its normal position.
●In all cases, avoid bending or twisting the cables. Do not bend any cable sharply. A sharp bend
can break the internal wires.
●Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.
●Never crease a SATA data cable.
●Do not rely on components like the drive cage, power supply, or computer cover to push cables
down into the chassis. Always position the cables to lay properly by themselves or in the cable
guides and chassis areas designed for cable routing.
When removing the power supply power cable from the connector on the system board, always follow
these steps:
1. Squeeze on the top of the retaining latch attached to the cable end of the connector.
2. Grasp the cable end of the connector and pull it straight out.
CAUTION: Always pull the connector — NEVER pull on the cable. Pulling on the cable could
damage the cable and result in a failed power supply.
78 Chapter 3 Component replacement information and guidelines
CPU (processor) and CPU heatsink
CAUTION: Observe the following cautions when removing or replacing the heatsink.
— When removing the heatsink, loosen all screws a little at a time to ensure the CPU remains level.
Do
not
fully loosen one screw, and then move on to the next.
— After you remove the CPU heatsink from the chassis, use alcohol and a soft cloth to clean the
thermal compound residue from the CPU and the heatsink, allowing the alcohol on the CPU and CPU
heatsink to dry completely.
— If you are reusing the original heatsink, apply thermal compound to the center of the CPU top
surface.
— If you are using a new CPU heatsink, do not apply thermal compound to the CPU because the
new heatsink already has thermal compound applied to the heatsink surface. Instead, remove the
thermal compound protective liner from the bottom of the new heatsink.
— Do not overtighten the heatsink screws. Overtightening can strip the threads in the chassis.
— Do not fully tighten one screw and then move on to the next. Instead, tighten all screws a little at a
time, ensuring that the CPU remains level.
CAUTION: Observe the following cautions when removing or replacing the CPU.
— If you are installing a second CPU, it must be of the same type as the first CPU.
— Internal components might be powered even when the computer is off. To prevent damage,
disconnect the computer power cord before you remove or install a component.
— The CPU socket contacts and pads are extremely fragile. Do not touch the CPU socket contacts or
the gold pads underneath the CPU. Use extreme care and handle the CPU only by the edges.
— The CPU socket contacts are delicate and bend easily. To avoid bending the contacts, use
extreme care when installing the CPU in the socket.
— Installing a processor incorrectly can damage the system board. Contact an HP authorized reseller
or service provider to install the processor. If you plan to install the processor yourself, view the entire
remove and replace video before you begin.
— Failure to follow the computer preparation instructions can result in an improperly installed
processor, causing extensive computer damage.
Component replacement guidelines 79
Expansion slots
This section identifies and describes computer expansion card slots, and presents card configuration
information.
Go to http://www.hp.com/go/quickspecs to learn which graphics cards are supported in the
workstation, how much memory each graphics card includes, and graphics card power requirements.
Card configuration restrictions for power supplies
CAUTION: To prevent damage, the overall power consumption of the computer (including I/O cards,
CPU, and memory) must not exceed the maximum rating of the computer power supply. For power
supply information, see Power supply specifications on page 104.
Choosing an expansion card slot
Whenever possible, use the following tips to help you select the proper slot for an expansion card:
●Use the PCIe x16 slot for the primary graphics card. If you do not use this slot for the graphics
card, only cards certified as After Market Options are supported.
●Install a second graphics card in the other PCIe x16 slot.
●Install a card in a slot that most closely matches its interface technology:
◦Install a PCIe Gen1 x16 or a PCIe Gen1 x8 card in the PCIe Gen2 x16 slot.
◦Install a PCIe Gen1 x4 card in the PCIe Gen1 x4 slot.
◦Install a PCIe Gen1 x1 card in the PCIe Gen1 x1 slot.
◦Install a PCI card in the PCI slot.
◦Whenever possible, install a PCIe x1 card in an x1 slot.
●Leave as much space as possible between cards (especially graphics cards) to allow heat to
dissipate more efficiently.
●For best operational efficiency, select a slot that:
◦Electrically matches the number of PCIe card lanes (for example, x1 in an x1 slot).
◦Has more lanes electrically.
◦Has fewer lanes, but is closer to your needs. For example, place an x16 card in an x4 slot,
and an x4 card in a an x1 slot.
●An x1 connector supports an x1 card only. While an x1 card can be inserted into a larger slot,
this may limit potential future card placement.

Hard disk drives and optical disc drives
Handling hard disk drives
CAUTION: Take proper precautions when handling hard disk drives to prevent loss of work and
damage to the computer or drive.
●Do not remove hard drives from the shipping package for storage. Keep hard drives in their
protective packaging until they are mounted in the computer.
●Always shut down the operating system, turn off the power, and unplug the power cord. Never
remove a drive while the computer is on or in standby mode.
●Before handling a drive, make sure you discharge static electricity. While handling a drive, avoid
touching the connector.
●Handle a drive carefully. Do not drop it from any height.
●To prevent possible ESD damage when the drive is installed, connect the drive power cable
before connecting the data cable. This discharges accumulated static electricity through the
drive power cable to the computer chassis.
●Do not use excessive force when inserting a drive.
●Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic
fields such as monitors or speakers.
●If you must mail a drive, use a bubble-pack mailer or other protective packaging and label the
package “Fragile: Handle With Care.”
Removal and replacement tips
●To verify the type, size, and capacity of the storage devices installed in the computer, run
Computer Setup (F10) Utility.
●Adding a new drive may require that you make new connections from the drive to the system
board. Note that:
◦The primary Serial ATA (SATA) hard drive must be connected to the dark blue primary
SATA connector on the system board labeled SATA0.
◦Connect a secondary hard drive to SATA.
◦Connect SATA optical drives to the black SATA2 connector.
◦Connect an optional eSATA adapter cable to the black ESATA connector on the system
board.
◦Connect a media card reader USB cable to the USB connector on the system board
labeled MEDIA. If the media card reader has a 1394 port, connect the 1394 cable to the
1394 PCI card.

BIOS errors and warnings
The BIOS generates warnings/errors on invalid memory configurations:
●If the BIOS can find a valid memory configuration by disabling plugged-in memory, it does so
and reports a warning during POST. the workstation can still be started. The warning will
indicate the location of the failed DIMM on the system board.
●If there is no way for the BIOS to obtain a valid memory configuration by disabling plugged-in
memory, the BIOS halts with a diagnostics 2006 code for memory error (five beeps and blinks).
DIMM installation guidelines
●Install only HP-approved DDR3 DIMMs
CAUTION: HP ships only DIMMs that are electrically and thermally compatible with this
workstation. Because third-party DIMMs might not be electrically or thermally compatible, they
are not supported by HP.
●Install only HP-approved DDR3 DIMMs. See http://www.hp.com/go/quickspecs to find DIMMs
that are compatible with the workstation.
●Do not intermix DIMMs of different technologies. ECC Unbuffered DIMMs (UDIMMs), Registered
DIMMs (RDIMMs), and Load Reduced DIMMs (LRDIMMs) are supported on HP Z Series
Workstations. Supported DIMM configurations on page 98 specifies which technologies are
supported on each platform.
CAUTION: DIMMs and their sockets are keyed for proper installation. To prevent socket or DIMM
damage, align these guides properly when installing DIMMs.

Power consumption and heat dissipation
Power consumption and heat dissipation specifications are available for multiple configurations. To
review available specifications, see http://www.hp.com/go/quickspecs.
To reach zero power consumption, unplug the workstation from the power outlet or use a power strip
with an on/off switch. For additional information about power-saving features, see the operating
system installation instructions.
This product is in compliance with U.S. Executive Order 13221.
Resetting the power supply
If an overload triggers the power supply overload protection, power is immediately disconnected.
To reset the power supply:
1. Disconnect the power cord from the workstation.
2. Determine what caused the overload and fix the problem. For troubleshooting information, see
Diagnostics and troubleshooting on page 112.
3. Reconnect the power cord and restart the workstation.
When you power off the workstation through the operating system, power consumption falls below
what is considered low power consumption but does not reach zero. This low power consumption
feature extends the life of the power supply.
System board
If you replace the system board:
●Make a note of the cable connections before disconnecting them from the system board.
●Follow good cable management practices. See Cable management on page 78.

Calling support
At times you might encounter an issue that requires support. When you call support:
●Have the computer readily accessible.
●Write down the computer serial numbers, product numbers, model names, and model numbers
and have them in front of you.
●Note any applicable error messages.
●Note any add-on options.
●Note the operating system.
●Note any third-party hardware or software.
●Note the details of any blinking LEDs on the front of the computer (tower and desktop
configurations) or on the side of the computer (all-in-one configurations).
●Note the applications you were using when you encountered the problem.
NOTE: When calling in for service or support, you might be asked for the product number (example:
PS988AV) of the computer. If the computer has a product number, it is generally located next to the
10- or 12-digit serial number of the computer.
NOTE: On most models, the serial number and product number labels can be found on the top or
side panel and at the rear of the computer (tower and desktop configurations) or on a pull-out card on
the side of the display (all-in-one configurations).
For a listing of all worldwide support phone numbers, go to http://www.hp.com/support, select your
region, and click Connect with HP in the upper-right corner.
Calling support 113
Locating ID labels
To assist in troubleshooting, product, serial, and authentication numbers are available on each
computer.
●All workstations have a serial number (unique for each workstation) and product number. Have
these numbers available when you contact support.
●The Certificate of Authentication (COA) is used for systems with Windows 7 preinstalled.
●The Genuine Microsoft Label (GML) is used for systems with Windows 8 preinstalled.
●A service label shows the build ID and Feature Byte strings, which are needed for system board
replacement.
In general, these labels can be found on the top, rear, or bottom of the chassis (tower and desktop
configuration). Your computer might look different from the illustration.

Diagnosis guidelines
If you encounter a problem with the computer, monitor, or software, the following sections provide a
list of general suggestions that help you isolate and focus on the problem before taking further action.
Diagnosis at startup
●Verify that the computer and monitor are plugged into a working electrical outlet.
●Remove all CDs, or USB drive keys from your system before turning it on.
●Verify that the computer is turned on and the blue power light is blue (normal operation) and not
red (error state).
●If you have installed an operating system other than the factory-installed operating system,
check to be sure that it is supported on your system by visiting http://www.hp.com/go/
quickspecs.
●Verify that the monitor is turned on and the green monitor light is on. Note that not all monitors
are equipped with LED lights to indicate their functionality.
●Turn up the brightness and contrast controls of the monitor if the monitor is dim.
Locating warranty information 115
Diagnosis during operation
●Look for blinking LEDs on the side of the computer. The blinking lights are error codes that will
help you diagnose the problem. Refer to the Diagnostic LED and audible (beep) codes
on page 145 section of this document for information on interpreting diagnostic lights and
audible codes.
●Check all cables for loose or incorrect connections.
●Wake the computer by pressing any key on the keyboard or the power button. If the system
remains in suspend mode, shut down the system by pressing and holding the power button for
at least four seconds, then press the power button again to restart the system. If the system
does not shut down, unplug the power cord, wait a few seconds, then plug it in again. If it does
not restart, press the power button to start the computer.
●Reconfigure the computer after installing a non–plug and play expansion board or other option.
●Be sure that all required device drivers have been installed. For example, if you have connected
a printer, you must install a printer driver.
●If you are working on a network, plug another computer with a different cable into the network
connection. There might be a problem with the network plug or cable.
●If you recently added new hardware, remove the hardware and verify if the computer functions
properly.
●If you recently installed new software, uninstall the software and verify if the computer functions
properly.
●If the screen is blank, plug the monitor into a different video port on the computer if one is
available. Alternatively, replace the monitor with a monitor that you know is working properly.
●Upgrade the BIOS. A new release of the BIOS might have been released that supports new
features or fixes your problem.
●Press the Caps Lock key. If the Caps Lock LED toggles on or off, the keyboard is operating
correctly.

Helpful hints
If you encounter a problem with the workstation, monitor, or software, the following general
suggestions might help you isolate and focus on the problem before taking further action.
At startup
●Verify that the workstation and monitor are plugged into a working electrical outlet.
●Remove all optical discs and USB drive keys from the drives before powering on the
workstation.
●Verify that the workstation is turned on and the power light is on.
●If you have installed an operating system other than the factory-installed operating system,
check to be sure that it is supported on your system by visiting http://www.hp.com/go/
quickspecs.
●Verify that the monitor is turned on and the green monitor light is on.
●Turn up the brightness and contrast controls of the monitor if the monitor is dim.
●If the workstation has multiple video sources and only a single monitor, the monitor must be
connected to the source selected as the primary VGA adapter. During startup, the other monitor
connectors are disabled; if the monitor is connected to one of these ports, it will not function after
Power-on Self Test (POST). You can select the default VGA source in Computer Setup (F10).
During operation
●Look for blinking LEDs on the workstation. The blinking lights are error codes that will help you
diagnose the problem. Refer to the
Diagnostic lights and audible (beep) codes
section of this
document for information on interpreting diagnostic lights and audible codes.
●Press and hold any key. If the system beeps, then your keyboard is operating correctly.
●Check all cables for loose or incorrect connections.
●Wake the workstation by pressing any key on the keyboard or the power button. If the system
remains in suspend mode, shut down the system by pressing and holding the power button for
at least four seconds, then press the power button again to restart the system. If the system
does not shut down, unplug the power cord, wait a few seconds, then plug it in again. If it does
not restart, press the power button to start the workstation.
●Reconfigure the workstation after installing a non–plug and play expansion board or other option.
Refer to the
Hardware installation problems
section of this document for instructions.
●Be sure that all required device drivers have been installed. For example, if you have connected
a printer, you must install a printer driver.
●If you are working on a network, plug another workstation with a different cable into the network
connection. There might be a problem with the network plug or cable.
●If you recently added new hardware, remove the hardware and verify if the workstation functions
properly.
●If you recently installed new software, uninstall the software and verify if the workstation
functions properly.
●If the monitor connected to a tower, desktop or all-in-one computer is blank:

Self-troubleshooting with HP Vision Diagnostics 139
Self-troubleshooting with HP PC Hardware Diagnostics
HP PC Hardware Diagnostics is a Unified Extensible Firmware Interface (UEFI) based diagnostic tool
that can be used by the end user or technical support personnel to view information about the system
configuration and to perform hardware troubleshooting. The diagnostic tool runs outside of the
operating system to isolate hardware failures from issues that might be caused by the operating
system or other software components.
HP PC Hardware Diagnostics:
●Easy to obtain:
◦Installed on original image of every system hard drive (HDD)
◦Core set of tests installed in the BIOS of every system
◦Download to a USB key drive
●Captures complete system configuration information, including:
◦System serial number, product ID number, asset tag, and model
◦Memory size and configuration
◦Processor information (including, type and speed)
◦Storage device information
◦HDD: Launches Drive Self Test (DST) SMART tests for SATA drives
◦Keyboard controller revision
◦Bundles of tests to perform a quick test or extensive test of the entire system
◦BIOS date and revision
●Diagnostic tests:
◦System tests (Start-up, Run-In and System Tune-Up)
◦Individual component tests (Hard Disk Test and Memory Tests)
●Diagnostic Failure Code Output — A unique, 24–digit Failure ID code is generated for each
failure:
◦Randomly generated, unique each occurrence
◦Identifies the specific components that did not pass validation
◦Includes warranty information with information about the customer’s service entitlement
◦Provides information about the model, serial number, test time stamp, and failure
◦Includes recommended actions with URL information on whom to contact
◦Generation of the failure code indicates a definite hardware failure – no additional
troubleshooting is required
●Error Log — The tool automatically saves an error log on the device from which the test was run
(either the hard drive or USB drive). This log is available for future access from the tool and
includes the test that was run, date of the test, and Pass/Fail information including the Failure ID
if one was generated.
140 Chapter 4 Diagnostics and troubleshooting
Downloading HP PC Hardware Diagnostics
NOTE: The most likely cause of the diagnostics file being unavailable on the hard drive is a hard
drive fault, or a missing or corrupted HP_TOOLS partition. For example, some corporate customers
reimage the workstation with their own custom image, which can remove the HP_TOOLs partition. In
this case, a SoftPaq is available from the HP website.
The HP UEFI Support Environment must be installed on and run from a FAT or FAT32 partition with a
volume name of HP_TOOLS. The installer gives you the option to install to the HDD or a USB drive. If
you install to the hard drive and the HP_TOOLS partition is not present, the installer prompts you to
create the HP_TOOLS partition. If you install to a USB drive, the installer renames the partition on the
USB drive to HP_TOOLS. If you use a custom image, you can create the HP_TOOLS partition
manually with FAT32 and make the volume name HP_TOOLS.
Follow these steps to download the HP PC Hardware Diagnostics utility from the HP website to a
USB key:
1. Navigate to http://www.hp.com and select Support & Drivers.
2. Select Drivers & Software.
3. Enter the product name: Z220 to search for the Z220 product media.
4. Select the specific model of HP Z220 Workstation.
5. Choose the software/driver language. English (International) is the default.
6. Select the appropriate operating system.
7. On the Quick jump to downloads by category list, click Diagnostic.
8. Next to HP UEFI Support Environment, click Download and save the file.
9. Double-click the downloaded file and follow the on-screen instructions to expand the contents of
the SoftPaq onto a USB key drive.
CAUTION: The HP_TOOLS partition is not protected and can therefore be deleted. For these
reasons, HP recommends that you do not place additional data on the HP_TOOLS partition. Because
the partition is not backed up, corruption or failure of the partition will result in loss of all data on the
partition, plus loss of UEFI functionality. You can find more information on http://www.hp.com/go/
techcenter/startup.

Accessing HP PC Hardware Diagnostics
The process to access the diagnostics tool is the same regardless of the location from which it is run.
The user presses ESC, while the system boots. This brings up the BIOS menu, which include an
option to run diagnostics (F2). Once selected, the BIOS searches for a diagnostic signature. The
diagnostic tool runs from the first location where the file is found.
The system searches for the file in the follow sequence: USB device, hard drive (HDD), and BIOS.
If the system does not find the diagnostics on either a USB device or the hard drive, the system
presents a core set diagnostics (memory and HDD) that are located in the BIOS. The BIOS version is
only accessible if the USB or hard drive versions are not available.
User interface
The first screen to appear is the Main Menu, which includes:
●The current version of the diagnostics
●The URL at which you can find more documentation about the diagnostics
It also includes the following options:
●System Information— Includes complete system, memory, and HDD

Hardware diagnostic tests
HP PC Hardware Diagnostics provides five sets of hardware diagnostic tests to validate the
functionality of hardware components (including the CPU, memory, graphics, and system board) prior
to booting the operating system.
If the operating system cannot load because of a hardware failure, the diagnostics can be used to
determine which hardware component has failed.
In the case of system failure, the diagnostics generate a unique 24–digit Failure ID code to identify
the specific components that did not pass validation.
Test Function
Start-Up Test Analyzes the main components to make sure they are functioning properly to start the computer, the
processor (CPU), the memory modules, and the hard drive. It checks the SMART attributes of the hard
drive and performs the built-in Self-Test.
Run-In Test Repeats the Start-up Test and checks for intermittent problems that the start-up test does not detect. Use
this test if the computer is having intermittent problems while running, that do not appear to be related to
system startup.
System Tune-
Up
Similar to the Start-Up Test, the System Tune-Up performs the Start-Up Test plus tests the video memory.
Hard Disk
Test
The Hard Disk Test allows the selection of the Quick Extensive Test or Extensive Test of user selected
drives in the system. The user can select a single drive, or they can select all of the drives in the system to
run concurrently. The tests consists of the following subtests:
●Quick Test
◦Hard Disk SMART Check
◦Hard Disk Short DST
●Extensive Test
◦Hard Disk SMART Check
◦Hard Disk Short DST
◦Hard Disk Optimized DST Check
◦Hard Disk Long DST
Memory Test Analyzes the physical condition of the memory modules and reports any faulty modules. If this test reports
an error, the faulty memory module(s) should be replaced immediately.
The Memory Test allows selection of the Quick Memory Test or Extensive Memory Test.
The Quick Test is the same version run in the Start-Up Test, and takes around five minutes for 4GB of
memory to complete.
The Extensive Test runs a longer version of the Memory Test, which adds additional pattern and transfer
types to make it a more comprehensive test of the memory. This test normally runs approximately eight
minutes/GB. Test times varies depending on system architecture, processor speed, and amount of
memory.

5 Configuring password security and
resetting CMOS
This chapter describes how to configure password security and to reset CMOS.
●Preparing to configure passwords on page 153
●Resetting the password jumper on page 154
●Clearing and resetting the CMOS on page 155
Preparing to configure passwords
Computer Setup (F10) Utility enables you to create setup and power-on passwords.
There are three possibilities for setting passwords:
●Define a setup password only. You will need the password to enter Computer Setup (F10) Utility,
but you will not need a password to start the workstation.
●Define a power-on password only. This password lets you start the workstation or enter the
setup utility.
●Define both. In this case, the setup password lets you start the workstation and enter the setup
utility. The power-on password starts the workstation but does not let you enter the setup utility,
After you create both passwords, you can use the setup password in place of the power-on password
as an override to log into the computer (a useful feature for a network administrator).
NOTE: You can only clear the passwords with the password jumper. Clearing CMOS does not clear
the passwords.
CAUTION: Before pressing the Clear CMOS button, back up your computer CMOS settings.
Pressing the Clear CMOS button resets CMOS values to factory defaults and erases customized
information, including asset numbers and special settings.
To back up the CMOS settings, run Computer Setup (F10) Utility and select Save to Diskette from the
File menu.
Preparing to configure passwords 153
Resetting the password jumper
Use the following procedure to disable the power-on or setup password features and clear the power-
on and setup passwords.
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 computer is plugged in, the power supply has voltage applied to the system
board, even when the computer 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 computer or optional
equipment. Before beginning these procedures, be sure that you are discharged of static electricity by
briefly touching a grounded metal object.
1. Access the jumper:
a. Shut down the operating system, turn off the computer and external devices, and then
disconnect the computer power cord and external devices from power outlets.
b. Disconnect any external devices.
c. Verify that the AC power cord is disconnected from the power outlet.
d. Open the workstation.
e. Locate the password header and jumper.
The password header is E49. The password jumper is blue so it can be easily identified.

A Linux technical notes
HP offers a variety of Linux solutions for HP workstation customers:
●HP certifies and supports Red Hat Enterprise Linux (RHEL) on HP workstations.
●HP certifies SUSE Linux Enterprise Desktop (SLED) on HP workstations.
●HP offers a SLED 11 preload on some Z Series Workstations.
For Linux setup and restore procedures, see the user guide for your workstation at
http://www.hp.com/support/workstation_manuals.
●System RAM
●Audio
●Network cards
●Hyper-Threading Technology
●NVIDIA Graphics Workstations
●AMD Graphics Workstations
NOTE: After you set up the operating system, make sure that the latest BIOS, drivers, and software
updates are installed.
CAUTION: Do not add optional hardware or third-party devices to the workstation until the operating
system is successfully installed. Adding hardware might cause errors and prevent the operating
system from installing correctly.
System RAM
HP supports different amounts of total RAM in various HP workstations, based on the number of
hardware DIMM slots and the capabilities of the system. The total memory supported for each
configuration is listed in the
Hardware Support Matrix for HP Linux Workstations
at
http://www.hp.com/support/linux_hardware_matrix.
Audio
All HP workstations come with built-in audio hardware. The audio hardware is supported by the
Advanced Linux Sound Architecture
(ALSA) drivers included with all modern Linux distributions.
The audio hardware provides basic playback and recording features. The ability to simultaneously
play audio from multiple sources, such as applications and CDs, is provided in the ALSA driver that
provides audio mixing. The performance of software audio mixing and playback is greatly improved in
ALSA version 1.0.13 and later.
After the driver is installed, the optional NVIDIA and AMD graphics cards that are supported in HP
workstations also provide audio functionality over HDMI. The signal can be passed through the
DisplayPort connector to a monitor with audio capabilities. The vendor driver must be installed. Such
a configuration might present two audio hardware choices. If you do not hear sound through the
speakers, one possible reason is that the graphics card (default) is selected for audio output instead
of the DisplayPort. Check the audio settings (for example, Sound in gnome-control-center).
System RAM 157
In some systems, embedded Intel HD graphics may also present a similar HDMI audio device that
can be used through the DisplayPort interface. No proprietary driver is needed for this device, just a
sufficiently recent kernel.
Network cards
All HP workstations include one or two integrated network interface controllers. Some support
optional NICs. Most Linux distributions have drivers for these interfaces.
Hyper-Threading Technology
The Z Series Workstations support Hyper-Threading Technology (HTT), an Intel technology that
improves processor performance by enabling the processor to simultaneously performing multiple
tasks. The operating system treats an HTT-enabled processor as two virtual processors and shares
the workload between them when possible. This feature can be used only if the operating system
support multiple processors and is specifically optimized for HTT.
To enable HTT:
1. During startup, press F10 to enter Computer Setup (F10) Utility.
2. Select Advanced > Device Options.
3. Set Hyper-Threading to Enable, and then press F10 to exit the menu.
4. Select File > Save Changes and Exit.
5. Restart the system to enable HTT.
NOTE: On most recent Linux distributions (including RHEL 5, RHEL 6, SLED 11, and updates to
those streams), the kernel automatically detects that HTT is enabled and works correctly.
158 Appendix A Linux technical notes
NVIDIA Graphics Workstations
Some workstation configurations come with NVIDIA Quadro graphics hardware. HP recommends the
use of NVIDIA drivers for best results on Linux systems.
HP provides recommended versions of the drivers with RPM-compatible installers for RHEL and
SLED distributions. These are available from the HP Installer Kit for Linux and from workstation driver
repositories on hp.com. When HP installers are used, their contents and documentation links are
located in the /opt/hp/nvidia folder.
When installing Linux on a workstation that contains an NVIDIA card, administrators should select a
VESA-compatible driver to avoid the instability that is experienced with some open-source versions of
the Nouveau and DRM drivers.
Open-source versions of Nouveau drivers and NVIDIA drivers cannot coexist in the same runtime
environment because they use the same hardware resources. If administrators create their own Linux
environments using NVIDIA drivers but choose not to use HP-packaged versions, HP recommends
that they manually append the following boot loader parameters to properly suppress the Nouveau
driver at runtime (grub example below):
kernel /vmlinuz ... rdblacklist=nouveau nouveau.modeset=0
This action is applied by HP installers but must be applied/restored under other circumstances.
To customize display characteristics and resolutions when the computer is using an NVIDIA driver,
execute the following command:
/usr/bin/nvidia-settings
To create and manipulate the /etc/X11/xorg.conf file, execute:
/usr/bin/nvidia-xconfig
NVIDIA Graphics Workstations 159
AMD Graphics Workstations
Some workstation configurations include AMD graphics hardware. HP recommends use of AMD
graphics drivers for best results on Linux systems.
HP also provides recommended versions of AMD graphics drivers with RPM-compatible installers for
RHEL and SLED distributions. These are available from the HP Installer Kit for Linux and workstation
driver support packages on hp.com.
The open source RADEON and RADEONHD drivers can conflict with the AMD graphics drivers by
claiming the hardware early in the boot process. The AMD driver installation process usually
blacklists conflicting drivers and turns off kernel mode-setting in the initial RAM image.
Administrator customization of the display characteristics and many other aspects of an AMD
graphics driver environment is available through the following command, which starts the Catalyst
Control Center:
/usr/bin/amdcccle
Some settings for AMD graphics, including reconfiguration of the /etc/X11/xorg.conf file, can be
accomplished through the many options provided by the following command:
/usr/bin/aticonfig
Information can be found in these directories after the driver is installed:
/opt/hp/ati
/usr/share/ati
/usr/share/doc/fglrx
If the automatic init script attempts to rebuild the kernel module, the name of the log file is /var/log/
fglrx-build.log.

Configuring Intel SATA RAID
This section describes how to use Intel
®
Rapid Storage Technology enterprise (Intel
®
RSTe) or Intel
®
Rapid Storage Technology (RST) to set up and manage SATA RAID volumes.
NOTE: These instructions apply to Windows-based systems. They also apply to Linux distributions
that include the isci kernel driver support for the RSTe technology. This driver is included on recent
releases of most upstream and enterprise distributions, and may be available for addition to some
previous releases. If this driver is not available in the distribution, or is not applicable to the platform
(e.g., the RST controller), the Software RAID solution is recommended.
You can create a SATA RAID array that contains up to the maximum number of internal SATA hard
disk drives and eSATA drives (if you use an optional eSATA bulkhead cable) supported on your
workstation.
Two or more hard drives must be attached to a controller (AHCI or SCU) for that controller's option
ROM to run. If two or more drives are on each controller, a unique option ROM executes for each
controller.
The Intel SATA AHCI option ROM and SCU option ROM configuration utilities run when you select
RAID+AHCI for the SATA emulation mode.

●Write Through:The configuration might result in slower performance.
●Always Write Back: The configuration results in optimal performance, but there is a risk of
data loss in the event of power failure.
●Write Back with BBU: If you have not installed BBU, write back is enabled only when the
battery has a sufficient charge. During a learning cycle, the caching policy reverts to write-
through until the learning cycle is complete.

Software RAID solution
This section summarizes software RAID considerations that are specific to the Linux environment,
and provides links to additional configuration resources.
Software RAID considerations
The Linux kernel software RAID driver (called
md
, for
multiple device
) offers integrated software RAID
without the need for additional hardware disk controllers or kernel patches. Unlike most hardware
RAID solutions, software RAID can be used with all types of disk technologies, including SATA, SAS,
SCSI, and solid-state drives. This software solution requires only minimal setup of the disks
themselves.
However, when ompared to hardware-based RAID, software RAID has disadvantages in managing
the disks, breaking up data as necessary, and managing parity data. The CPU must assume some
extra loading: disk-intensive workloads result in roughly double the CPU overhead (for example, from
15% to 30%). For most applications, this overhead is easily handled by excess headroom in the
processors. But for some applications where disk and CPU performance are very well balanced and
already near bottleneck levels, this additional CPU overhead can become troublesome.
Hardware RAID offers advantages because of its large hardware cache and the capability for better
scheduling of operations in parallel. However, software RAID offers more flexibility for disk and disk
controller setup. Additionally, hardware RAID requires that a failed RAID controller must be replaced
with an identical model to avoid data loss, whereas software RAID imposes no such requirements.
Some software RAID schemes offer data protection through mirroring (copying the data to multiple
disks in case one disk fails) or parity data (checksums that allow error detection and limited rebuilding
of data in case of a failure). For all software RAID solutions on HP workstations, redundancy can be
restored only after the system is shut down so that the failed drive can be replaced. This replacement
requires only a minimum amount of work.
Performance considerations
Disk I/O bandwidth is typically limited by the system bus speeds, the disk controller, and the disks
themselves. The balance of these hardware limitations, as affected by the software configuration,
determines the location of the any bottleneck is in the system.
Several RAID levels offer improved performance relative to stand-alone disk performance. If disk
throughput is restricted because of a single disk controller, RAID can probably do little to improve
performance until another controller is added. Conversely, if raw disk performance is the bottleneck, a
tuned software RAID solution can dramatically improve the throughput. The slower disk performance
is, relative to the rest of the system, the better RAID performance will scale, because the slowest
piece of the performance pipeline is being directly addressed by moving to RAID.
