Product specifications 7

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 specifications listed in this
document.

NOTE: The ambient upper limit of 35°C (95°F) is only good up to 1524 m (5000 ft) elevation. There is a

1°C (33.8°F) per 304.8 m (1000 ft) derating above 1524 m (5000 ft). So, at 3,048 m (10,000 ft), the
upper ambient air temperature limit is 30°C (86°F).

●

For cabinet installation, be sure that adequate cabinet ventilation and 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.

Power management and performance features 9

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 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 off and power is diverted to the active cores to increase their
performance.

Turbo Boost is enabled and disabled with Computer Setup (f10) Utility.

http://www.hp.com/go/quickspecs to determine if your CPU supports Turbo Boost.

Go to

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.

SATA Defaults

Storage Options eSATA Port

Allows you to set a SATA port as an eSATA port for use with an external drive. Default is enabled.

This setting affects only the port with the black connector, labeled as eSATA on the system board. This
port should have the eSATA back panel connector attached to use eSATA drives. For more information,
see the eSATA white paper at

SATA Emulation

Allows you to choose how the SATA controller and devices are accessed by the operating system. There
are three supported options.

CAUTION: SATA emulation changes may prevent access to existing hard drive data and degrade or

corrupt established volumes.

IDE—Is the most backward-compatible setting of the three options. Operating systems usually do not
require additional driver support in IDE mode.

RAID (default option)—Allows DOS and boot access to RAID volumes. Use this mode with the RAID device
driver loaded in the operating system to take advantage of RAID features.

www.hp.com.

14 Chapter 2 System management

AHCI—Allows operating systems with AHCI device drivers loaded to take advantage of more advanced
features of the SATA controller.

NOTE: The RAID/AHCI device driver must be installed prior to attempting to boot from a RAID/AHCI

volume. If you attempt to boot from a RAID/AHCI volume without the required device driver installed, the
system will crash (blue screen). RAID volumes may become corrupted if they are booted to after disabling
RAID.

Removable Media Boot

Enables/disables ability to boot the system from removable media. Default is enabled.

Max eSATA Speed

Allows you to choose 1.5 Gbps or 3.0 Gpbs as the maximum eSATA speed. By default, the speed is limited
to 1.5 Gbps for maximum reliability.

CAUTION: Consult your eSATA drive and cable manufacturer before enabling 3.0 Gpbs speed. Some

drive and cable combinations may not run reliably at 3.0 Gpbs.

Boot Order Allows you to:

●

UEFI Boot Sources: Specify the order in which UEFI boot sources (such as a internal hard drive, USB
hard drive, USB optical drive, or internal optical drive) are checked for a bootable operating system
image. Each device on the list may be individually excluded from or included for consideration as a
bootable operating system source.

UEFI boot sources always have precedence over legacy boot sources.

●

Legacy Boot Sources: Specify the order in which legacy boot sources (such as a network interface
card, internal hard drive, USB optical drive, or internal optical drive) are checked for a bootable
operating system image. Each device on the list may be individually excluded from or included for
consideration as a bootable operating system source.

Specify the order of attached hard drives. The first hard drive in the order will have priority in the
boot sequence and will be recognized as drive C (if any devices are attached).

Shortcut to Temporarily Override Boot Order

To boot one time from a device other than the default device specified in Boot Order, restart the
computer and press esc (to access the boot menu) and then f9 (Boot Order), or press f9 (bypassing the
boot menu) when the monitor light turns green. After POST is completed, a list of bootable devices is
displayed. Use the arrow keys to select the preferred bootable device and press enter. The computer then
boots from the selected non-default device for this one time.

The MBR contains information needed to successfully boot from a disk and to access the data stored on
the disk. Master Boot Record Security may prevent unintentional or malicious changes to the MBR, such
as those caused by some viruses or by the incorrect use of certain disk utilities. It also allows you to
recover the "last known good" MBR, should changes to the MBR be detected when the system is
restarted.

When MBR Security is enabled, the BIOS prevents any changes being made to the MBR of the current
bootable disk while in MS-DOS or Windows Safe Mode.

NOTE: Most operating systems control access to the MBR of the current bootable disk; the BIOS cannot

prevent changes that may occur while the operating system is running.

Restores the backup Master Boot Record to the current bootable disk. Default is disabled.

System Security (these
options are hardware
dependent)

Only appears if all of the following conditions are true:

●

MBR security is enabled

●

A backup copy of the MBR has been previously saved

●

The current bootable disk is the same disk from which the backup copy was saved

CAUTION: Restoring a previously saved MBR after a disk utility or operating system has modified the

MBR, may cause the data on the disk to become inaccessible. Only restore a previously saved MBR if you
are confident that the current bootable disk MBR has been corrupted or infected with a virus.

Desktop management 23

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 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, 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.

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 file store. Driver versions supported by SSM are noted with a special icon on the software, the
driver download website, and on the Support Software CD.

To download the utility or to obtain more information about SSM, see

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.

To upgrade the BIOS, download the latest SoftPaq images from

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

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

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 created from a SoftPaq. The BIOS image CD programs the system ROM with a
valid image.

26 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 file 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 flash drive, such as an HP

DriveKey, into a USB port.

3. Turn off 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 a setup password has been established, the caps lock light is illuminated and you are prompted for
the password.

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 offers several solutions for controlling access to valuable components and information:

●

HP ProtectTools Embedded Security prevents unauthorized access to data, checks system integrity, and
authenticates third-party users attempting system access.

●

Security features such as ProtectTools and the Smart Cover Sensor (side access panel sensor) help
prevent unauthorized access to the data and to the internal components of the computer.

●

By disabling parallel, serial, or USB ports, or by disabling removable-media boot capability, you can
protect valuable data assets.

●

Memory Change and Side access panel sensor (Smart Cover Sensor) alerts can be forwarded to system
management applications to deliver proactive notification of tampering with a computer’s internal
components.

ProtectTools, the Smart Cover Sensor, and the side access panel solenoid lock (Hood Lock) are available as
options on select systems.

Desktop management 27

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

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.

Prevents transfer of data through the integrated serial, parallel, USB, or infrared
interface

Prevents use of the computer until the password is entered (applies to initial system
startup and restarts)

Prevents reconfiguration of the computer (through the Setup utility) until the
password is entered

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 fit the
previously defined customer profile, this might not be acceptable. For users who fit this profile, it might be a
tolerable risk, given the nature of the data stored on the hard 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 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

28 Chapter 2 System management

employee 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 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.

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 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. Under Enable/Disable DriveLock options, select Enable, and then press f10 to enable DriveLock for a

specific drive.

NOTE: To set the DriveLock master password, select Master.

CAUTION: If you forget the DriveLock password, the drive is unusable.

6. Enter a new user password (1 to 32 characters long), and then press f10 to accept.

Desktop management 29

7. Enter the password again in the Enter New Password Again field. If you forget this password, the drive is

rendered permanently disabled.

8. Select File > Save Changes and Exit, and then press enter to accept the changes. After you press enter,

the computer performs a cold start before invoking the DriveLock function.

When the computer starts, you are prompted to enter the DriveLock password for each 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.

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 drive­locked 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

The power-on password prevents unauthorized use of the computer by requiring entry of a password to
access applications or data when the computer is turned on or restarted. The setup password specifically
prevents unauthorized access to Computer Setup (f10) Utility and can also be used as an override to the
power-on password. When prompted for the power-on password, entering the setup password instead
enables access to the computer.

You can establish a network-wide setup password to enable the system administrator to log in to all network
systems to perform maintenance without needing to know the power-on password.

Establishing a setup password using Computer Setup (f10) Utility

Fault notification and recovery

Fault notification and recovery features combine innovative hardware and software technology to prevent
the loss of critical data and minimize unplanned downtime.

If the computer is connected to a network that is managed by HP CMS, the computer sends a fault notice to
the network management application. With HP CMS, you can also remotely schedule diagnostics to run on
managed PCs and create a summary report of failed tests.

ECC fault prediction

When the computer encounters an excessive number of error checking and correcting (ECC) memory errors, it
displays a local alert message. This message contains information about the errant DIMM, enabling you to
take action before you experience noncorrectable memory errors. ECC DIMMs are standard on this computer.

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 fire and chemical burn if the

battery is handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose of in
water or fire, 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 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.

40 Chapter 3 Component replacement information and guidelines

●

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 41

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 first CPU.

— Internal components might be powered even when the computer is off. To prevent damage, disconnect
the computer power cord before you remove or install a component.

— The CPU socket contacts and pads are extremely fragile. Do not touch the CPU socket contacts or the gold
pads underneath the CPU. Use extreme care and handle the CPU only by the edges.

— The CPU socket contacts are delicate and bend easily. To avoid bending the contacts, use extreme care
when installing the CPU in the socket.

— Installing a processor incorrectly can damage the system board. Contact an HP authorized reseller or
service provider to install the processor. If you plan to install the processor yourself, view the entire remove
and replace video before you begin.

— Failure to follow the computer preparation instructions can result in an improperly installed processor,
causing extensive computer damage.

much memory each graphics card includes, and graphics card power requirements.

Card configuration restrictions for power supplies

CAUTION: To prevent damage, the overall power consumption of the computer (including I/O cards, CPU,

and memory) must not exceed the maximum rating of the computer power supply. For power supply
information, see

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:

◦

◦

Power supply specifications on page 48.

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 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.

Component replacement guidelines 43

Slot identification and description

Maximum power used by all slots must not exceed total system power and is subject to configuration
limitations.

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 off the power, and unplug the power cord. Never remove
a drive while the computer is on or in standby mode.

●

Before handling a drive, make sure you discharge static electricity. While handling a drive, avoid
touching the connector.

●

Handle a drive carefully. Do not drop it from any height.

●

To prevent possible ESD damage when the drive is installed, connect the drive power cable before
connecting the data cable. This discharges accumulated static electricity through the drive power cable
to the computer chassis.

●

Do not use excessive force when inserting a drive.

●

Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic fields
such as monitors or speakers.

●

If you must mail a drive, use a bubble-pack mailer or other protective packaging and label the package
“Fragile: Handle With Care.”

Removal and replacement tips

●

To verify the type, size, and capacity of the storage devices installed in the computer, run Computer
Setup (f10) Utility.

●

Adding a new drive may require that you make new connections from the drive to the system board.
Note that:

Component replacement guidelines 45

◦

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.

6 Configuring password security and

resetting CMOS

This chapter describes how to configure password security and to reset CMOS.

●

Preparing to configure passwords on page 75

●

Resetting the password jumper on page 76

●

Clearing and resetting the CMOS on page 77

Preparing to configure passwords

Computer Setup (f10) Utility enables you to create setup and power-on passwords.

There are three possibilities for setting passwords:

●

Define a setup password only. You will need the password to enter Computer Setup (f10) Utility, but you
will not need a password to start the workstation.

●

Define a power-on password only. This password lets you start the workstation or enter the setup
utility.

●

Define both. In this case, the setup password lets you start the workstation and enter the setup utility.
The power-on password starts the workstation but does not let you enter the setup utility,

After you create both passwords, you can use the setup password in place of the power-on password as an
override to log into the computer (a useful feature for a network administrator).

NOTE: You can only clear the passwords with the password jumper. Clearing CMOS does not clear the

passwords.

CAUTION: Before pressing the Clear CMOS button, back up your computer CMOS settings.

Pressing the Clear CMOS button resets CMOS values to factory defaults and erases customized information,
including asset numbers and special settings.

To back up the CMOS settings, run Computer Setup (f10) Utility and select Save to Diskette from the File
menu.

Preparing to configure passwords 75

Resetting the password jumper

Use the following procedure to disable the power-on or setup password features and clear the power-on and
setup passwords.

●

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

linux_hardware_matrix.

http://www.hp.com/

http://www.hp.com/support/

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

System RAM 79

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.

80 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 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.

Configuring Intel SATA RAID

This section describes how to use Intel® Rapid Storage Technology (RST) to set up and manage SATA RAID
volumes.

NOTE: These instructions apply to Windows-based systems. They also apply to Linux distributions that

include the isci kernel driver support for the RSTe technology. This driver is included on recent releases of
most upstream and enterprise distributions, and may be available for addition to some previous releases. If
this driver is not available in the distribution, or is not applicable to the platform (e.g., the RST controller), the
Software RAID solution is recommended.

You can create a SATA RAID array that contains up to the maximum number of internal SATA hard drives and
eSATA drives (if you use an optional eSATA bulkhead cable) supported on your workstation.

The Intel SATA option ROM configuration utilities run when you select RAID for the SATA emulation mode.

Two or more hard drives must be attached to the controller for the option ROM to run.

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, 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: disk­intensive workloads result in roughly double the CPU overhead (for example, from 15% to 30%). For most
applications, this overhead is easily handled by excess headroom in the processors. But for some
applications where disk and CPU performance are very well balanced and already near bottleneck levels, this
additional CPU overhead can become troublesome.

Hardware RAID offers advantages because of its large hardware cache and the capability for better
scheduling of operations in parallel. However, software RAID offers more flexibility for disk and disk
controller setup. Additionally, hardware RAID requires that a failed RAID controller must be replaced with an
identical model to avoid data loss, whereas software RAID imposes no such requirements.

Some software RAID schemes offer data protection through mirroring (copying the data to multiple disks in
case one disk fails) or parity data (checksums that allow error detection and limited rebuilding of data in case

Software RAID solution 85

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.
