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).
22
●
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.

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 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 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 processor supports Turbo Boost.
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 Computer Setup (F10) Utility.

Chapter 2 System management
Initial computer configuration 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 Configuration and Power Interface (ACPI) hardware provide further
assistance with recovery of system software, configuration management and troubleshooting, and power
management.
Support for specific features described in this guide can vary by model and software version.
The best deployment method depends on the information technology environment and processes.

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 file 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 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 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 flash failure.
For example, if a power failure occurs during a ROM upgrade, 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,
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 file in the SoftPaq to create a BIOS image CD or
USB flash 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 flash 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 off, 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 off 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.
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:
●
Security features such as the Smart Cover Sensor (side access panel sensor) help prevent unauthorized
access to the data and to the internal components of the computer
●
Capability for protecting valuable data assets by disabling parallel, serial, or USB ports, or by disabling
removable-media boot capability
●
Memory Change and Side access panel sensor (Smart Cover Sensor) alerts, which can be forwarded to
system management applications to deliver proactive notification of tampering with a computer’s
internal components
The Smart Cover Sensor and cable lock are available as options on select systems.
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
For more information about Computer Setup (F10) Utility, see Computer Setup (F10) Utility menu on page 27.
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
Prevents use of the computer until the password is entered (applies to initial system
startup and restarts)
Setup Password
Prevents reconfiguration of the computer (through Computer Setup (F10) Utility) until
the password is entered
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.
If both DriveLock passwords are lost, the hard drive is inaccessible. For users who do not fit the previously
defined customer profile, this outcome might not be acceptable. For users who fit this profile, 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 configuring 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
find themselves locked out of a hard drive and unable to perform routine checks for unauthorized software,
other asset control functions, and support.
For users with less stringent security requirements, HP does not recommend enabling DriveLock. Users in
this category include personal users, or users who do not maintain sensitive data on their hard drives as a
common practice. For these users, the potential loss of a hard drive resulting from forgetting both passwords
is much greater than the value of the data DriveLock 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 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 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 field. 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 specifically 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 reconfiguration of the
computer (through the use of Computer Setup (F10) Utility) until the password is entered.
To establish a setup password using the Computer Setup (F10) Utility menu:
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.

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 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.
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 first processor.
— 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 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 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,
processor, and memory) must not exceed the maximum rating of the computer power supply. For power
supply information, see Power supply specifications 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 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.

NOTE: Slots two, four, and five are PCIe GEN3 slots. Slot two is the primary graphics slot; slot five is the
secondary graphics slot.
Slots three and four use open-ended PCIe connectors, so a PCIe x16 card can be inserted. This allows the
workstation to support more PCIe x16 expansion cards. A x16 card typically trains and runs at the maximum
lane width available by the expansion slot. The card runs at the reduced lane width, with a corresponding
performance decrease. Graphics cards greater than 75 watts require the use of an auxiliary power cable
adapter.

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 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.
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.

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 76.
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 49.

Chapter 4 Diagnostics and troubleshooting
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 native Windows 7 preinstalled.
NOTE:
Systems with Windows 8.1 downgraded to Windows 7 do not have a COA.
●
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.
Diagnosis during operation
78
●
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 91 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.
Chapter 4 Diagnostics and troubleshooting

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
80
●
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).
Chapter 4 Diagnostics and troubleshooting
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:
◦
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.
◦
Verify that the computer and monitor are plugged into a working electrical outlet.
◦
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 internal display on an all-in-one computer is blank, open the computer and make sure the
graphics card is properly installed.
●
Upgrade the BIOS. A new release of the BIOS might have been released that supports new features or
fixes your problem.
Customer Self-Repair program
Under the Customer Self-Repair program, you can order a replacement part and install the part without
onsite HP technical assistance. Customer self-repair may be required for some components. See
http://www.hp.com/go/selfrepair for information on the program.

Configuring password security and
resetting CMOS
This chapter describes how to configure password security and to reset CMOS.
●
Preparing to configure passwords on page 98
●
Resetting the password jumper on page 99
●
Clearing and resetting the CMOS on page 100
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 Main//
menu.

Linux technical notes
HP offers a variety of Linux solutions for HP workstation customers:
●
HP offers an Ubuntu preload on some new Z Series Workstations.
●
HP certifies and supports Ubuntu on HP workstations.
●
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 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 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
102 Appendix A Linux technical notes
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).
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 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
specifically 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 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 VESAcompatible 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.
Network cards 103
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
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/fglrxbuild.log.

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 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 (sSATA) 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 configuration utilities run when you select RAID+AHCI for the SATA
emulation mode.
Configuring system BIOS
To set up a RAID configuration, the emulation mode must be set to RAID+AHCI in Computer Setup (F10)
Utility. This is the default setting. If the mode has been changed, follow these steps to reinstate it.
1.
During startup, press F10 to enter Computer Setup (F10) Utility. Use the arrow keys to navigate and
select options.
2.

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 solidstate 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 processor must assume some extra loading:
disk-intensive workloads result in roughly double the processor 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 processor performance are very well balanced and already near bottleneck
levels, this additional processor 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.
