14 Chapter 1 Hardware overview
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.)
●Be sure that the ambient air temperature falls within the environmental specications 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, be sure that adequate cabinet ventilation and the ambient temperature within
the cabinet does not exceed specied limits.
●Never restrict the incoming or outgoing airow of the workstation by blocking any vents or air intakes,
as shown in the following gure.

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 specically optimized for HTT.
Use 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
Your workstation 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 o and power is diverted to the active cores to increase their
performance.
Turbo Boost is enabled and disabled with Computer Setup (F10) Utility.
Go to http://www.hp.com/go/quickspecs to determine if your CPU supports Turbo Boost.
Non-Uniform Memory Access (NUMA)
Non-uniform memory access (NUMA) is available on some 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 conguration, and the degree to
which the applications used are designed to be NUMA-aware/ecient.
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, and then select Main > Save Changes and
Exit. Your change takes eect when the computer restarts.
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 specications.

Desktop management 29
Initial computer conguration 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 by:
●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 HDD-based HP Recovery Manager ROM-based setup, and ACPI hardware provide further assistance with
recovery of system software, conguration management and troubleshooting, and power management.
Support for specic 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
Remote system installation enables starting and setting up the computer using software and conguration
information on a network server. This feature is usually used for system setup and conguration and can be
used to:
●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 on-screen instructions to continue the installation process. The
default boot order is a BIOS conguration setting that can be changed to always attempt a network boot.
Copying a setup conguration to another computer
This section provides information about replicating the computer setup.
CAUTION: Setup conguration is model-specic. File system corruption can result if source and target
computers are not the same model.
To copy a setup conguration:
1. Select a setup conguration to copy, and then restart the computer.
2. As soon as you start or restart the computer, press and hold F10 until you enter Computer Setup (F10)
Utility. If necessary, press enter to bypass the title screen.

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 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 le 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 ash ROM. By establishing an administrator password in
Computer Setup (F10) Utility, you can protect unauthorized users from modifying the BIOS settings.
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
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 created from a SoftPaq. The BIOS image CD programs the system ROM with a
valid image.
32 Chapter 2 System management
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 key.
Recovering the computer by using FailSafe 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 or insert a USB BIOS image ash drive, such as an HP DriveKey,
into a USB port.
3. Turn o the computer, and then turn it back on.
If no BIOS image CD or USB media is found, you are prompted to insert one and restart the computer.
If an administrator password has been established, the caps lock light is illuminated and you are
prompted for the password.
4. Enter the administrator password.
If the computer starts from the CD or ash drive and successfully reprograms the ROM, three keyboard
lights are illuminated and a rising-tone series of beeps signals successful recovery.
5. Remove the CD or ash drive 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 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 oers 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 notication 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 33
You can manage security settings as follows:
●Locally with Computer Setup (F10) Utility
●Remotely with HP CMS or HP System Software Manager (SSM), which enable the secure, consistent
deployment and control of security settings from a simple command line utility
The following Computer Setup (F10) Utility features let you manage computer security.
Feature Purpose
Removable Media Boot Control Prevents booting from removable media drives
Serial, Parallel, USB, or Infrared
Interface Control
Prevents transfer of data through the integrated serial, parallel, USB, or infrared
interface
Power-On Password Prevents use of the computer until the password is entered (applies to initial system
startup and restarts)
Ddministrator Password Prevents reconguration of the computer (through the Setup utility) until the
password is entered
Network Server Mode Provides unique security features for computers used as servers
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+AHCI or RAID.
DriveLock is 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.
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.
If both DriveLock passwords are lost, the hard drive is rendered unusable. For users who do not t the
previously dened customer prole, this might not be acceptable. For users who t this prole, it 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 conguring the hard 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 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
34 Chapter 2 System management
sets both DriveLock passwords before leaving the company. In such a scenario, the hard drive is unusable and
requires replacement. 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.
Access to Computer Setup (F10) Utility and DriveLock can be restricted through the administrator password.
By specifying an administrator 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
conguration 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 you turn on the computer, 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. To enable DriveLock for a specic drive, select Enable DriveLock
NOTE: To set the DriveLock master password, select Set DriveLock Master Password.
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.
Desktop management 35
7. Enter the password again in the Enter New Password Again eld. 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.
When you start or restart the computer, you must enter DriveLock passwords. 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 restart-start behavior is consistent with the DriveLock feature.
Password security
This computer supports security password features, which can be established through the Computer Setup
Utilities menu.
This computer supports two security password features that are established through the Computer Setup
Utilities menu: administrator password and power-on password. When you establish only an administrator
password, any user can access all the information on the computer except Computer Setup. When you
establish only a power-on password, the power-on password is required to access Computer Setup and any
other information on the computer. When you establish both passwords, only the administrator password will
give you access to Computer Setup.
When both passwords are set, the administrator password can also be used in place of the power-on
password as an override to log in to the computer. This is a useful feature for a network administrator.
If you forget one or both passwords, you can clear all passwords by powering o the system, opening the
cover, temporarily removing the PSWD jumper, and booting once. This will erase the administrator and
power-on passwords. You must restore the jumper to create new passwords.
CAUTION: Pushing the CMOS button with power removed will reset the BIOS settings to factory defaults. It
may be useful to back up the BIOS settings or save them as custom defaults before resetting them in case
they are needed later. Back up can be performed in Computer Setup or using the BiosCongUtility tool
available from www.hp.com. See Computer Setup (F10) Utilities on page 18 for information on backing up the
BIOS settings.

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
electronic 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.
●Before handling or touching a sensitive component or assembly, ground yourself by touching a
grounded metal object.
●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 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.

Grounding the work
area to prevent static
damage
●Cover the work surface with approved
static-dissipative material. Use a wrist strap
connected to the work surface, and properly
grounded tools and equipment.
●Use static-dissipative mats, foot straps, or
air ionizers to give added protection.
●Disconnect power and input signals before
inserting and removing connectors or test
equipment.
●Use xtures made of static-safe materials
when xtures must directly contact dissipative
surfaces.
Service considerations 43
●Handle electrostatic-sensitive components,
parts, and assemblies by the case or PCB
laminate. Handle them only in static-free
work areas.
●Keep work area free of conductive materials,
such as plastic assembly aids and Styrofoam.
●Use eld service tools (such as cutters,

Battery
The battery that comes with the computer provides power to the real-time clock and has a minimum lifetime
of about three years. Observe the following warning and caution when replacing the battery.
WARNING! HP Z Series Workstations use lithium batteries. There is a risk of re and chemical burn if the
battery is handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose of in
water or re, or expose battery to temperatures higher than 60°C (140°F).
CAUTION: Before removing the battery, back up the CMOS settings in case they are lost when the battery is
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.
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 45
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 make sure 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 rst CPU.
— 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 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.

Expansion slots
This section identies and describes computer expansion card slots, and presents card conguration
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 conguration 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 specications on page 56.
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 certied 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 Gen3 x16 slot.
◦Install a PCIe Gen1 x4 card in the PCIe Gen2 x4 slot.
◦Install a PCIe Gen1 x1 card in the PCIe Gen2 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 eciently.
●For best operational eciency, 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 disc 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.”
Component replacement guidelines 51
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 SATA1.
◦Connect SATA optical drives to the black SATA2 connector.
◦Connect an optional eSATA adapter cable to the black ESATA connector SATA3 on the system board.
(Tower only)
◦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 congurations:
●If the BIOS can nd a valid memory conguration 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 conguration by disabling plugged-in memory,
the BIOS halts with a diagnostics 2006 code for memory error (ve 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 nd DIMMs that are
compatible with the workstation.
●Do not intermix DIMMs of dierent technologies. ECC Unbuered DIMMs (UDIMMs), Registered DIMMs
(RDIMMs), and Load Reduced DIMMs (LRDIMMs) are supported on your workstations. Supported DIMM
congurations on page 53 species 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.

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.
Locating ID labels 61
●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, go to 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.
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 Interpreting system validation diagnostic front panel LEDs and
audible codes on page 80 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.
●Recongure 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 dierent 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 dierent 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
xes your problem.
●Press the caps lock key. If the caps lock LED toggles on or o, the keyboard is operating correctly.
Troubleshooting checklist
Before running diagnostic utilities, make sure that the following conditions are met:
●The computer is connected to a working electrical outlet and powered on, and the power light is
illuminated.
●The monitor (for tower or desktop congurations) is connected to a working electrical outlet and
powered on, and the power light is illuminated.
●The monitor brightness and contrast are properly adjusted.
●The keyboard is operating correctly (press and hold any key and listen for a beep).
●All cables are properly connected.

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 is plugged into a functional AC outlet.
●Remove all optical discs and USB ash drives before starting the workstation.
●Verify that the workstation is on and the power light is on.
●If you have installed an operating system other than the factory-installed operating system, conrm
that it is supported on your system by going to http://www.hp.com/go/quickspecs.
●Verify that the internal display panel is lit.
●If the internal display panel is dim, turn up the brightness.
●If you have an external monitor:
◦Verify that the monitor is plugged into a functional AC outlet.
◦Verify that the monitor is on and the green monitor light is on.
◦If the monitor is dim, turn up the brightness and contrast controls.
During operation
●Beeps and blinking lights on the workstation are error codes that can help you diagnose problems. For
more information on interpreting these codes, see the Diagnostic LED and audible (beep) codes section
in the Maintenance and Service Guide for your workstation.
●Press and hold any key. If the system beeps, your keyboard is operating correctly.
●Check all cables for loose or incorrect connections.
●Wake the workstation by pressing the power button or any key on the keyboard. 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.

workstation.
64 Chapter 4 Diagnostics and troubleshooting
●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, use another cable to plug your workstation into the network
connection. If you still cannot connect, there might be a problem with the network plug.
●If you recently added new hardware, remove the hardware to see whether the workstation functions
properly.
●If you recently installed new software, uninstall the software to see whether the workstation functions
properly.
●If the internal display panel on an all-in-one workstation is blank, open the workstation and be sure that
both ends of the cable between the system board and the internal display panel are connected. If you
are using a graphics card, verify that the card is properly installed.
●Upgrade the BIOS. A new release of the BIOS might have been released that supports new features or
xes your problem.

5Conguring password security and
resetting CMOS
This chapter describes how to congure password security and to reset CMOS.
Preparing to congure passwords
Computer Setup (F10) Utility enables you to create setup and power-on passwords.
There are three possibilities for setting passwords:
●Dene an administrator password only. You will need the password to enter Computer Setup (F10)
Utility, but you will not need a password to start the workstation.
●Dene a power-on password only. This password lets you start the workstation or enter the setup utility.
●Dene both. In this case, the administrator 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 administrator 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.
Resetting the password jumper
CAUTION: Stringent security is a mode where there is no physical bypass of the password function. If
enabled, removing the password jumper will be ignored. To enable this mode, change the security setting
Clear Password Jumper in Password Policies to Ignore.
If you lose or forget the password when in stringent security mode, the system can only be reset by System
Management Command. This is a way for HP Service and Support to provide a secure method to access the
BIOS and command a password reset for a specically identied unit under the direction of the owner. This
scenario may not be covered under warranty.
To prevent needing a customer service event to restore access to the system, record your congured
administrator and power-on passwords in a safe place away from your computer.
To disable the power-on or administrator password features, or to clear the power-on or administrator
passwords, complete the following steps:
82 Chapter 5 Conguring password security and resetting CMOS
1. Shut down the operating system properly, then turn o the computer and any external devices, and
disconnect the power cord from the power outlet.
2. With the power cord disconnected, press the power button again to drain the system of any residual
power.
WARNING! To reduce the risk of personal injury from electrical shock and/or 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 always has voltage applied to the
system board even when the unit is turned o. Failure to disconnect the power cord can result in
damage to the system.
Static electricity can damage the electronic components of the computer or optional equipment. Before
beginning these procedures, ensure that you are discharged of static electricity by briey touching a
grounded metal object. See the Safety & Regulatory Information guide for more information.
3. Remove the access panel.
4. Locate the header and jumper.
NOTE: The password jumper is green so that it can be easily identied.
5. Remove the jumper from pins 1 and 2.
6. Place the jumper on either pin 1 or 2, but not both, so that it does not get lost.
7. Replace the access panel and reconnect the external equipment.
8. Plug in the computer and turn on power. Allow the operating system to start. This clears the current
passwords and disables the password features.
9. Shut down the computer, unplug the power, and disconnect the external equipment.
10. Remove the access panel.
11. Place the jumper on pins 1 and 2.
12. Replace the access panel.
13. Reconnect the external equipment and plug in the computer.
Clearing and resetting the BIOS
The CMOS button resets BIOS settings to default, but does not clear the passwords or aect any of the other
Security settings. On Intel systems with advanced manageability features, the CMOS button will also partially
unprovision AMT.
Clearing and resetting the BIOS 83
1. Turn o the computer and any external devices, and disconnect the power cord from the power outlet.
2. Disconnect the keyboard, monitor, and any other external equipment connected to the computer.
WARNING! To reduce the risk of personal injury from electrical shock and/or 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 always has voltage applied to the
system board even when the unit is turned o. Failure to disconnect the power cord can result in
damage to the system.
Static electricity can damage the electronic components of the computer or optional equipment. Before
beginning these procedures, ensure that you are discharged of static electricity by briey touching a
grounded metal object. See the Safety & Regulatory Information guide for more information.
3. Remove the access panel.
CAUTION: Pushing the CMOS button will reset CMOS values to factory defaults. It is important to back
up the computer CMOS settings before resetting them in case they are needed later. Back up is easily
done through Computer Setup. See Computer Setup (F10) Utilities on page 18 for information on
backing up the CMOS settings.
4. Locate, press, and hold the CMOS button in for ve seconds.
NOTE: Make sure you have disconnected the AC power cord from the wall outlet. The CMOS button will
not clear CMOS if the power cord is connected.
5. Replace the access panel.
6. Reconnect the external devices.
7. Plug in the computer and turn on power.
NOTE: You will receive POST error messages after clearing CMOS and rebooting advising you that
conguration changes have occurred. Use Computer Setup to reset any special system setups along with
the date and time.
For instructions on Computer Setup, see Computer Setup (F10) Utilities on page 18.

A Linux technical notes
HP oers a variety of Linux solutions for HP workstation customers:
●HP oers an Ubuntu preload on some Z Series Workstations.
●HP certies and supports Ubuntu on some HP workstations.
●HP certies and supports Red Hat Enterprise Linux (RHEL) on HP workstations.
●HP certies SUSE Linux Enterprise Desktop (SLED) on HP workstations.
●HP oers a SLED 11 preload on some older 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 dierent 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 conguration 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 conguration
might present two audio hardware choices. If you do not hear sound through the speakers, one possible
System RAM 85
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).
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 suciently 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 perform 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
specically optimized for HTT.
To enable HTT:
1. During startup, press F10 to enter Computer Setup (F10) Utility.
2. Select Advanced > Performance Options.
3. Set Intel Hyper-Threading Technology to Enable, and then press F10 to exit the menu.
4. Select Main > Save Changes and Exit.
5. Restart the system to enable HTT.
NOTE: On most recent Linux distributions (including RHEL 6, SLED 11, and updates to those streams), the
kernel automatically detects that HTT is enabled and works correctly.
NVIDIA Graphics Workstations
Some workstation congurations 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.
86 Appendix A Linux technical notes
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 le, execute:
/usr/bin/nvidia-xconfig
AMD Graphics Workstations
Some workstation congurations 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 conict with the AMD graphics drivers by claiming the
hardware early in the boot process. The AMD driver installation process usually blacklists conicting drivers
and turns o 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 reconguration of the /etc/X11/xorg.conf le, 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 le is /var/log/fglrx-
build.log.

Software RAID solution
This section summarizes software RAID considerations that are specic to the Linux environment, and
provides links to additional conguration resources.
Software RAID considerations
The Linux kernel software RAID driver (called md, for multiple device) oers 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, SCSI, and solid-state drives.
This software solution requires only minimal setup of the disks themselves.
However, when compared 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 oers advantages because of its large hardware cache and the capability for better
scheduling of operations in parallel. However, software RAID oers more exibility 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 oer 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
90 Appendix B Conguring RAID devices
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 aected by the software conguration, determines
the location of the any bottleneck is in the system.
Several RAID levels oer 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.
