Environmental specications 21
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 specications 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 specied limits.
●
Never restrict the incoming or outgoing airow of the workstation by blocking any vents or air intakes,
as shown in the following gure.

Power management features 23
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 specically optimized for HTT.
Use the Computer Setup (F10) Utility to enable HTT.
Go to http://www.hp.com/go/quickspecs to determine if your processor 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 processor to run at frequencies above the normal frequency. When all processor
cores are not necessary for the workload, inactive cores are turned o 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 processor supports Turbo Boost.
BIOS ROM
The BIOS ROM is a collection of machine language applications stored as rmware in ROM. It includes
functions such as Power-On Self-Test (POST), PCI device initialization, Plug and Play support, power
management, and Computer Setup (F10) Utility.
Go to http://www.hp.com/go/quickspecs to review the latest BIOS ROM specications.

32 Chapter 2 System management
Initial computer conguration and deployment
The computer includes a preinstalled system software image. After a brief software unbundling process, the
computer is ready to use.
If you prefer to replace the preinstalled software image with a customized set of system and application
software, you can deploy a customized software image using either of the following methods:
●
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 ROM-based setup and Advanced Conguration and Power Interface (ACPI) hardware provide further
assistance with recovery of system software, conguration management and troubleshooting, and power
management.
Support for specic features described in this guide can vary by model and software version.
The best deployment method depends on the information technology environment and processes.
Installing a remote system
When the computer has been congured as a remote system, you can start it and set it up by using software
and conguration information on a network server. This feature is usually used for system setup and
conguration and can be used to perform the following functions:
●
Deploy a software image on new PCs
●
Format a hard drive
●
Install application software or drivers
●
Update the operating system, application software, or drivers
To initiate a remote system installation, press F12 when F12=Network Service Boot appears in the lower
right corner of the HP logo screen. Follow the onscreen instructions to continue the installation process. The
default boot order can be changed in the BIOS so that the system always attempts to boot from the network.

updates for the HP client PC models in your environment. By specifying your models, operating system, and
language, you can quickly locate, sort, and select the SoftPaqs you need. For more information, go to
http://www8.hp.com/us/en/ads/clientmanagement/drivers-bios.html#softpaq-download-mng.
34 Chapter 2 System management
HP System Software Manager
HP System Software Manager (SSM) is a utility that is available on Windows computers. It 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 le store. Driver versions supported by SSM are noted with a special icon in the software, on the driver
download website, and on the Support Software CD.
To download the utility or to obtain more information about SSM, go to http://www8.hp.com/us/en/ads/
clientmanagement/drivers-bios.html#system-sw-mng.
ROM Flash
BIOS settings are stored on a programmable ash 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 be sure that 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 turned 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, go to http://www.hp.com/go/ssm, and enter the name of the
computer.
FailSafe Boot Block
FailSafe Boot Block enables BIOS recovery in the unlikely event of a ROM ash failure.
For example, if a power failure occurs during a ROM upgrade, Boot Block uses a ash-protected section of the
ROM to verify a valid system ROM ash 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, FailSafe
Boot Block provides enough support to start the computer from a BIOS image CD that has been 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 le in the SoftPaq to create a BIOS image CD or
USB ash drive.
Desktop management 35
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 ash drives or discs in the optical drives.
2. Insert a BIOS image CD into the DVD drive. You can also use USB media such as an HP DriveKey.
3. Turn the computer o, and then turn it on.
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 turns on 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
turn on and a rising-tone series of beeps signals successful recovery.
5. Remove the boot media and turn o the computer.
6. Restart the computer.
Workstation security
This section provides information about providing system security through asset tracking, password security,
hard drive locking, and chassis locks.
Asset tracking
Asset tracking features provide data that can be managed using HP Systems Insight Manager (HP SIM), HP
Console Management Controller (CMC), or other systems-management applications.

The following Computer Setup (F10) Utility features let you manage computer security.
36 Chapter 2 System management
Feature Purpose
Removable Media Boot Control Prevents booting from removable media drives
USB Interface Control Prevents transfer of data through the integrated USB interface
Power-On Password
Setup Password
SATA hard drive security
HP computers include the HP DriveLock facility for SATA hard drives to prevent unauthorized access to data.
WARNING! Enabling DriveLock can render a SATA hard 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) Utility functions. It is only
available when hard drives that support the ATA security command set are detected. On HP computers, it is
not available when the SATA emulation mode is RAID.
DriveLock is for HP customers for whom data security is the 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.
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 drive is replicated on a corporate information system or is regularly
backed up.
Prevents use of the computer until the password is entered (applies to initial system
startup and restarts)
Prevents reconguration of the computer (through Computer Setup (F10) Utility) until
the password is entered
If both DriveLock passwords are lost, the hard drive is inaccessible. For users who do not t the previously
dened customer prole, this outcome might not be acceptable. For users who t this prole, the outcome
might be a tolerable risk, given the nature of the data stored on the hard drive.
DriveLock applications
The most practical use of DriveLock is in a corporate environment. The system administrator would be
responsible for conguring the hard drive, which involves setting the DriveLock master password and a
temporary user password. If the system administrator forgets 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 restore
access to the hard drive.
HP recommends that corporate system administrators who enable DriveLock also establish a corporate policy
for setting and maintaining master passwords. This precaution will prevent loss of information if an employee
sets both DriveLock passwords before leaving the company. In such a scenario, the hard drive is inaccessible
and must be replaced. Likewise, by not setting a master password, system administrators might nd
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 protects.
Desktop management 37
Access to Computer Setup (F10) Utility 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 drives that support the ATA security command set are detected, DriveLock appears under the
Security menu in the Computer Setup (F10) Utility 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
conguration of DriveLock is typically performed by a system administrator, a master password should be set
rst.
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 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.
Enabling DriveLock
To enable and set the DriveLock user password:
1. Turn on or restart the computer.
2. As soon as the computer is turned on, repeatedly press the F10 key until Computer Setup (F10) Utility
starts.
If you do not press F10 at the appropriate time, you must restart the computer, and then repeatedly
press F10 to access the utility.
3. Select Security and then select DriveLock Security.
4. For each DriveLock-capable drive, select the drive by pressing Enter.
5. Under Enable/Disable DriveLock options, select Enable, and then press Enter to enable DriveLock for
that drive.
NOTE: To set the DriveLock master password, select Master.
CAUTION: If you forget the DriveLock password, the drive is inaccessible.
6. Enter a new user password (1 to 32 characters long), and then press Enter to accept.
7. Enter the password again in the Enter New Password Again eld. If you forget this password, the drive
is permanently disabled.
8. Select Main and then select Save Changes and Exit. 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 DriveLockcapable 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.
38 Chapter 2 System management
In a single-drive computer, when DriveLock is 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 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.
Password security
The power-on password prevents unauthorized access to applications or data when the computer is turned
on or restarted. The setup password specically prevents unauthorized access to the Computer Setup (F10)
Utility and can also be used as an override to the power-on password. An administrator can enter the setup
password at the prompt for the power-on password and gain 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 the Computer Setup (F10) Utility prevents reconguration of the
computer (through the use of Computer Setup (F10) Utility) until the password is entered.

1. Turn on or restart the computer.
2. As soon as the computer is turned 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, and then repeatedly
press F10 to access the utility.
3. Select Security and then select Set up BIOS Administrator Password. Follow the onscreen instructions.
4. Before exiting, select Main and then select Save Changes and Exit.
Establishing a power-on password using computer setup
Establishing a power-on password through Computer Setup (F10) Utility prevents access to the computer
when power is connected, unless you specify the password. When a power-on password is set, Computer
Setup (F10) Utility presents Password Options in the Security menu. The password options include Network
Server Mode and Password Prompt on Warm Boot.
When Network Server Mode is disabled, you must enter the password when the computer is turned on and the
key icon appears on the monitor. When Password Prompt on Warm Boot is enabled, you must enter the
password. The password must also be entered each time the computer is restarted. When Network Server
Mode is enabled, the password prompt is not presented during POST.
To enable Network Server Mode, you must set a power-on password under Advanced > Password Options.
This option enables the computer to start without requiring the power-on password, but the keyboard and
mouse are locked until you enter the password.
To establish a power-on password through the Computer (F10) menu:

Use the following items to help prevent ESD damage:
●
Wrist straps — These are exible 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 t 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 oors or dissipative oor mats, use
them on both feet with a maximum of one megohm ± 10% resistance between the operator and
ground.
Static shielding materials provide the following levels of protection.

removed. Use Computer Setup (F10) Utility to back up the settings.
NOTE: Do not dispose of batteries, battery packs, and accumulators with general household waste.
48 Chapter 3 Component replacement information and guidelines
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 ow
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.
Component replacement guidelines 49
Processor and processor 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 processor remains level. Do
not fully loosen one screw, and then move on to the next.
— After you remove the processor heatsink from the chassis, use alcohol and a soft cloth to clean the thermal
compound residue from the processor and the heatsink, allowing the alcohol on the processor and processor
heatsink to dry completely.
— If you are reusing the original heatsink, apply thermal compound to the center of the processor top
surface.
— If you are using a new processor heatsink, do not apply thermal compound to the processor 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 processor remains level.
CAUTION: Observe the following cautions when removing or replacing the processor.
— If you are installing a second processor, it must be of the same type as the rst processor.
— Internal components might be powered even when the computer is o. To prevent damage, disconnect the
computer power cord before you remove or install a component.
— The processor socket contacts and pads are extremely fragile. Do not touch the processor socket contacts
or the gold pads underneath the processor. Use extreme care and handle the processor only by the edges.
— The processor socket contacts are delicate and bend easily. To avoid bending the contacts, use extreme
care when installing the processor 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.

Expansion slots
This section identies and describes computer expansion card slots, and presents card conguration
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 conguration restrictions for power supplies
CAUTION: To prevent damage, the overall power consumption of the computer (including I/O cards,
processor, and memory) must not exceed the maximum rating of the computer power supply. For power
supply information, see Power supply specications on page 69.
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 certied 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 eciently.
●
For best operational eciency, 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 drives and optical drives
Handling hard drives
CAUTION: Take proper precautions when handling hard 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 o 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 elds
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.
Please note the following:
—
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.
