18 Chapter 1 Hardware overview
Ensuring proper ventilation
Proper ventilation for the system is important for workstation operation. Follow these guidelines:
●
Operate the workstation on a sturdy, level surface.
●
Provide at least 15.24 cm (6 inches) of clearance at the front and back of the workstation. (Workstation
models vary.)
●
Be sure that the ambient air temperature falls within the environmental 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.
Ensuring proper ventilation 19

20 Chapter 2 System management
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.

Power management and performance features 21
Non-Uniform Memory Access (NUMA)
Non-uniform memory access (NUMA) is available on some workstations. NUMA can improve memory
bandwidth and latency for multi-process or multi-threaded applications or workloads. Observed
performance improvements depend on the operating system, customer workload, system configuration, and
the degree to which the applications used are designed to be NUMA-aware/efficient.
NUMA requires that both processor sockets be populated. Installed memory should be balanced between
both processors for maximum performance.
NUMA is enabled if Memory Node Interleave is disabled in the system BIOS. To do this, press f10 during
startup to enter Computer Setup (f10) Utility. Select Advanced > Chipset/Memory. Use the arrow keys to set
Memory Node Interleave to Disable. Press f10 to exit the menu, and then select File > Save Changes and
Exit. Your change takes effect when the computer restarts.
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.

When a device is selected, detailed information and options are displayed. The following options might be
presented:
●
Hard Drive: Size, model, firmware version, serial number, connector color.
Translation mode (ATA disks only)
Lets you select the translation mode to be used for the device. This enables the BIOS to access disks
partitioned and formatted on other systems and may be necessary for users of older versions of
UNIX (e.g., SCO UNIX version 3.2). Options are Automatic, Bit-Shift, LBA Assisted, User, and Off.
Available only when the drive translation mode is set to User, allows you to specify the parameters
(logical cylinders, heads, and sectors per track) used by the BIOS to translate disk I/O requests (from
the operating system or an application) into terms the hard drive can accept. Logical cylinders may
not exceed 1024. The number of heads may not exceed 256. The number of sectors per track may
not exceed 63.
CAUTION: Ordinarily, the translation mode selected automatically by the BIOS should not be
changed. If the selected translation mode is not compatible with the translation mode that was
active when the disk was partitioned and formatted, the data on the disk will be inaccessible.
●

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.
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.

Desktop management 39
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

40 Chapter 2 System management
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.
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.
4. Enter the setup password.
If the computer starts from the CD or flash drive and successfully reprograms the ROM, three keyboard
lights are illuminated and a rising-tone series of beeps signals successful recovery.
5. Remove the CD or flash drive 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.
Desktop management 41
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:
●
●
●
●
ProtectTools, the Smart Cover Sensor, and the side access panel solenoid lock (Hood Lock) are available as
options on select systems.
You can manage security settings as follows:
●
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.
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

42 Chapter 2 System management
SATA hard drive security
HP computers include the HP DriveLock facility for SATA hard drives to prevent unauthorized access to data.
WARNING! Enabling DriveLock can render a SATA hard drive permanently inaccessible if the master
password is lost or forgotten. No method exists to recover the password or access the data.
DriveLock has been implemented as an extension to Computer Setup (f10) Utility functions. It is only
available when hard drives that support the ATA security command set are detected. On HP computers, it is
not available when the SATA emulation mode is RAID+AHCI or RAID.
DriveLock is for HP customers for whom data security is a paramount concern. For such customers, the cost
of a hard drive and the loss of the data stored on it is inconsequential when compared to the damage that
could result from unauthorized access to its contents.
To balance this level of security with the need to address the issue of a forgotten password, the HP
implementation of DriveLock employs a two-password security scheme. One password is intended to be set
and used by a system administrator, while the other is typically set and used by the user.
No "back door" can be used to unlock the drive if both passwords are lost. Therefore, DriveLock is most safely
used when the data contained on the hard drive is replicated on a corporate information system or is
regularly backed up.
If both DriveLock passwords are lost, the hard drive is rendered unusable. For users who do not 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.
Desktop management 43
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
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.
44 Chapter 2 System management
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.
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.
Desktop management 45
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
Establishing a setup password through Computer Setup (f10) Utility prevents reconfiguration of the
computer (through the use of Computer Setup (f10) Utility) until the password is entered.

Product recycling 57
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.
58 Chapter 3 Component replacement information and guidelines
CPU (processor) and CPU heatsink
CAUTION: Observe the following cautions when removing or replacing the heatsink.
— When removing the heatsink, loosen all screws a little at a time to 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.

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 69.
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.

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:
◦
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.
