Installing and Customizing the Software
NOTE: If the computer was shipped with Windows Vista loaded, you will be prompted to register the
computer with HP Total Care before installing the operating system. You will see a brief movie followed
by an online registration form. Fill out the form, click the Begin button, and follow the instructions on the
screen.
CAUTION: Do not add optional hardware or third-party devices to the computer until the operating
system is successfully installed. Doing so may cause errors and prevent the operating system from
installing properly.
Installing the Operating System
The first time you turn on the computer, the operating system is installed automatically. This process
takes about 5 to 10 minutes, depending on which operating system is being installed. Carefully read
and follow the instructions on the screen to complete the installation.
CAUTION: Once the automatic installation has begun, DO NOT TURN OFF THE COMPUTER UNTIL
THE PROCESS IS COMPLETE. Turning off the computer during the installation process may damage
the software that runs the computer or prevent its proper installation.
NOTE: If the computer shipped with more than one operating system language on the hard drive, the
installation process could take up to 60 minutes.
If your computer was not shipped with a Microsoft operating system, some portions of this documentation
do not apply. Additional information is available in online help after you install the operating system.
Installing or Upgrading Device Drivers
When installing optional hardware devices after the operating system installation is complete, you must
also install the drivers for each of the devices.
If prompted for the i386 directory, replace the path specification with C:\i386, or use the Browse button
in the dialog box to locate the i386 folder. This action points the operating system to the appropriate
drivers.
Obtain the latest support software , including support software for the operating system from
http://www.hp.com/support. Select your country and language, select Download drivers and
software, enter the model number of the computer, and press Enter.

HP Backup and Recovery Manager
The HP Backup and Recovery Manager is an easy-to-use, versatile application that allows you to back
up and recover the primary hard drive on the PC. The application works within Windows to create
backups of Windows, all applications, and all data files. Backups can be scheduled to occur
automatically at designated intervals, or they can be initiated manually. Important files can be archived
separately from regular backups.
HP Backup and Recovery Manager is preinstalled on the hard drive's Recovery Partition.
Recovery Points and file backups can be copied to CD or DVD discs, while all backups can be copied
to network or secondary hard disks.
HP highly recommends that you create a Recovery Disc Set immediately before using the computer
and schedule regular automatic Recovery Point backups.
To create the Recovery Disc Set:

ROM to allow the unit to boot through the network to a PXE server. This is typically used to
download a corporate image to a hard drive. The NIC option ROM takes up memory space
below 1MB commonly referred to as DOS Compatibility Hole (DCH) space. This space is
limited. This F10 option will allow users to disable the downloading of this embedded NIC option
ROM thus giving more DCH space for additional PCI cards which may need option ROM space.
The default will be to have the NIC option-ROM-enabled.
Recovering the Configuration Settings
This method of recovery requires that you first perform the Save to Removable Media command with
the Computer Setup (F10) Utility before Restore is needed. (See Save to Removable Media

HP Client Management Interface
Regardless of the system management tools your IT department uses, managing both your hardware
and software assets is important to keeping your IT costs low and your business agile. The IT
Remote System Installation
23
administrator can access the HP Client Management Interface by writing simple scripts and integrating
those scripts to the management solution of their choice.
With the HP Client Management Interface (HP CMI), new HP business computers seamlessly integrate
into your managed IT environment. HP CMI provides an interface that simplifies the integration of HP
business computers with popular industry system management tools (including Microsoft Systems
Management Server, IBM Tivoli Software, and HP Operations) and custom inhouse developed
management applications. Using HP CMI, systems management tools and applications can request indepth client inventory, receive health status information, and manage system BIOS settings by
communicating directly with the client computer, reducing the need for agent or connector software to
achieve integration.
HP Client Management Interface is based on industry standards that include Microsoft Windows
Management Interface (MS WMI), Web-Based Enterprise Management (WBEM), System Management
BIOS (SMBIOS), and Advanced Configuration and Power Interface (ACPI). HP CMI is a foundation
technology utilized in HP Client Management Solutions. With HP CMI, HP gives you flexibility in choosing
how you manage your HP client computers.
HP Client Management Interface used in conjunction with system management software can:
●
Request in-depth client inventory information—Capture detailed information about the processors,
hard drives, memory, BIOS, drivers, including sensor information (such as fan speed, voltage, and
temperature).
●
Receive health status information—Subscribe for a wide range of client hardware alerts (such as
over-temperature, fan stall, and hardware configuration changes) to be sent to the system
management console, application, or to the local client computer. Alerts are sent real-time when
triggered by hardware events.
●
Manage system BIOS settings—Perform F10 functions including setting and changing the BIOS
passwords and computer boot order remotely from your system management console on any or
all of your client systems without having to visit each machine.
For more information on HP Client Management Interface, refer to http://www.hp.com/go/hpcmi/.
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. To download HP SoftPaq
Download Manager, visit http://h20331.www2.hp.com/Hpsub/cache/509658-0-0-225-121.html.
HP System Software Manager
HP System Software Manager (SSM) is a free utility that automates remote deployment of device drivers
and BIOS updates for your networked HP business PCs. When SSM runs, it silently (without user
interaction) determines the revision levels of drivers and BIOS installed on each networked client system
and compares this inventory against system software SoftPaqs that have been tested and stored in a
central file store. SSM then automatically updates any down-revision system software on the networked
PCs to the later levels available in the file store. Since SSM only allows distribution of SoftPaq updates
to the correct client system models, administrators can confidently and efficiently use SSM to keep
system software updated.
System Software Manager integrates with enterprise software distribution tools such as HP
Configuration Management Solution, HP Client Manager for Altiris, and Microsoft Systems Management
24
Chapter 4 Desktop Management
Server (SMS). Using SSM, you can distribute customer-created or third-party updates that have been
packaged in the SSM-format.
SSM may be downloaded at no charge by visiting http://www.hp.com/go/ssm.
NOTE: SSM does not currently support remote ROM flash on systems that have Windows Vista
BitLocker enabled and are using TPM measurements to protect the BitLocker keys because flashing
the BIOS would invalidate the trust signature that BitLocker created for the platform. Disable BitLocker
via Group Policy in order to flash the system BIOS.
You can enable BitLocker support without TPM measurements of BIOS to avoid invalidating the
BitLocker keys. HP recommends you keep a secure backup of the BitLocker credentials in case of
recovery emergencies.

business desktops, notebooks, or workstations. Starting with new business desktops, notebooks, and
workstations released in 2006, all will ship with HP Backup and Recovery Manager.
ROM Flash
The computer's BIOS is stored in a programmable flash ROM (read only memory). By establishing a
setup password in the Computer Setup (F10) Utility, you can protect the ROM from being unintentionally
updated or overwritten. This is important to ensure the operating integrity of the computer. Should you
need or want to upgrade the BIOS, you may download the latest BIOS images from the HP driver and
support page, http://www.hp.com/support/files.
CAUTION: For maximum ROM protection, be sure to establish a setup password. The setup password
prevents unauthorized ROM upgrades. System Software Manager allows the system administrator to
set the setup password on one or more PCs simultaneously. For more information, visit
http://www.hp.com/go/ssm.
Remote ROM Flash
Remote ROM Flash allows the system administrator to safely upgrade the BIOS on remote HP
computers directly from the centralized network management console. Enabling the system
administrator to perform this task remotely on multiple computers results in a consistent deployment of,
and greater control over, HP PC BIOS images over the network. It also results in greater productivity
and lower total cost of ownership.
NOTE: SSM does not currently support remote ROM flash on systems that have Windows Vista
BitLocker enabled and are using TPM measurements to protect the BitLocker keys because flashing
the BIOS would invalidate the trust signature that BitLocker created for the platform. Disable BitLocker
via Group Policy in order to flash the system BIOS.
The computer must be powered on, or turned on through Remote Wakeup, to take advantage of Remote
ROM Flash.
For more information on Remote ROM Flash, refer to the HP Client Manager Software or System
Software Manager at http://www.hp.com/go/ssm/.

HPQFlash
The HPQFlash utility is used to locally update or restore the system BIOS of individual PCs from a
Windows operating system.
For more information on HPQFlash, visit http://www.hp.com/support/files and enter the model number
of the computer when prompted.
Boot Block Emergency Recovery Mode
Boot Block Emergency Recovery Mode permits system recovery in the unlikely event of a ROM flash
failure. For example, if a power failure were to occur during a BIOS upgrade, the ROM flash would be
incomplete. This would render the system BIOS unusable. The Boot Block is a flash-protected section
of the ROM that contains code that checks for a valid system BIOS image when the system is turned
on.
●
If the system BIOS image is valid, the system starts normally.
●
If the system BIOS image is not valid, a failsafe Boot Block BIOS provides enough support to search
removable media for BIOS image files. If an appropriate BIOS image file is found, it is automatically
flashed into the ROM.
When an invalid system BIOS image is detected, the system power LED will blink red 8 times, one blink
every second. Simultaneously, the speaker will beep 8 times. If the portion of the system ROM containing
the video option ROM image is not corrupt, Boot Block Emergency Recovery Mode will be displayed
on the screen.
To recover the system after it enters Boot Block Emergency Recovery Mode, complete the following
steps:
1.
Turn off the power.
2.
Insert a CD or USB flash device containing the desired BIOS image file in the root directory.
NOTE: The media must be formatted using the FAT12, FAT16, or FAT32 file system.
3.
Turn on the computer.
If no appropriate BIOS image is found, you will be prompted to insert media containing a BIOS
image file.
If the system successfully reprograms the ROM, the system will automatically power off.
4.
Remove the removable media used to upgrade the BIOS.
5.
Turn the power on to restart the computer.
NOTE: BitLocker prevents Windows Vista from booting when a CD containing the BIOS image file is
in an optical drive. If BitLocker is enabled, remove this CD before attempting to boot to Windows Vista.
Replicating the Setup
The following procedures give an administrator the ability to easily copy one setup configuration to other
computers of the same model. This allows for faster, more consistent configuration of multiple
computers.
32
Chapter 4 Desktop Management
NOTE: Both procedures require a diskette drive or a supported USB flash media device, such as an
HP Drive Key.
Copying to Single Computer
CAUTION: A setup configuration is model-specific. File system corruption may result if source and

Copying to Multiple Computers
CAUTION: A setup configuration is model-specific. File system corruption may result if source and
target computers are not the same model. For example, do not copy the setup configuration from a
dc7xxx PC to a dx7xxx PC.
This method takes a little longer to prepare the configuration diskette or USB flash media device, but
copying the configuration to target computers is significantly faster.
Replicating the Setup

or Compaq and most other USB flash media devices have this preinstalled image. If the USB flash media
device being used does not have this image, use the procedure later in this section (see Unsupported
USB Flash Media Device on page 36).
34
Chapter 4 Desktop Management
To create a bootable USB flash media device, you must have:
●
a supported USB flash media device
●
a bootable DOS diskette with the FDISK and SYS programs (If SYS is not available, FORMAT may
be used, but all existing files on the USB flash media device will be lost.)
●
a PC that is bootable from a USB flash media device
CAUTION: Some older PCs may not be bootable from a USB flash media device. If the default boot
order in the Computer Setup (F10) Utility lists the USB device before the hard drive, the computer can
be booted from a USB flash media device. Otherwise, a bootable diskette must be used.

DriveLock
DriveLock is an industry-standard security feature that prevents unauthorized access to the data on ATA
hard. DriveLock has been implemented as an extension to Computer Setup. It is only available when
hard drives that support the ATA Security command set are detected. DriveLock is intended for HP
customers for whom data security is the paramount concern. For such customers, the cost of the hard
drive and the loss of the data stored on it is inconsequential when compared with the damage that could
result from unauthorized access to its contents. In order to balance this level of security with the practical
need to accommodate a forgotten password, the HP implementation of DriveLock employs a twopassword 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 end-user. There is no "back-door" that 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.
In the event that both DriveLock passwords are lost, the hard drive is rendered unusable. For users who
do not fit the previously defined customer profile, this may be an unacceptable risk. For users who do
fit the customer profile, it may be a tolerable risk given the nature of the data stored on the hard drive.
Using DriveLock
When one or more hard drives that support the ATA Security command set are detected, the DriveLock
option appears under the Security menu in Computer Setup. The user is presented with options to set
Asset Tracking and Security
43
the master password or to enable DriveLock. A user password must be provided in order to enable
DriveLock. Since 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 keep it disabled. This will give the administrator the ability to
modify DriveLock settings if the drive is locked in the future. Once the master password is set, the system
administrator may enable DriveLock or choose to keep it disabled.
If a locked hard drive is present, POST will require a password to unlock the device. If a power-on
password is set and it matches the device’s user password, POST will not prompt the user to re-enter
the password. Otherwise, the user will be prompted to enter a DriveLock password. On a cold boot,
either the master or the user password may be used. On a warm boot, enter the same password used
to unlock the drive during the preceding cold-boot. Users will have two attempts to enter a correct
password. On a cold boot, if neither attempt succeeds, POST will continue but the drive will remain
inaccessible. On a warm boot or restart from Windows, if neither attempt succeeds, POST will halt and
the user will be instructed to cycle power.
DriveLock Applications
The most practical use of the DriveLock security feature is in a corporate environment. The system
administrator would be responsible for configuring the hard drive which would involve, among other
things, setting the DriveLock master password and a temporary user password. In the event that the
user forgets the user password or the equipment is passed on to another employee, the master
password can always be used to reset the user password and regain access to the hard drive.
HP recommends that corporate system administrators who choose to enable DriveLock also establish
a corporate policy for setting and maintaining master passwords. This should be done to prevent a
situation where an employee intentionally or unintentionally sets both DriveLock passwords before
leaving the company. In such a scenario, the hard drive would be rendered unusable and require
replacement. Likewise, by not setting a master password, system administrators may 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 has been designed to protect. Access
to Computer Setup and DriveLock can be restricted through the Setup password. By specifying a Setup
password and not giving it to end users, system administrators are able to restrict users from enabling
DriveLock.

PATA Device Information
The USDT model is the only product that supports a PATA optical drive. No PATA drives are supported
on any other model.
ATA SMART Drives
The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal
Computers have built-in drive failure prediction that warns the user or network administrator of an
impending failure or crash of the hard drive. The SMART drive tracks fault prediction and failure
indication parameters such as reallocated sector count, spin retry count, and calibration retry count. If
the drive determines that a failure is imminent, it generates a fault alert.
Hard Drive Capacities
The combination of the file system and the operating system used in the computer determines the
maximum usable size of a drive partition. A drive partition is the largest segment of a drive that may be
properly accessed by the operating system. A single hard drive may therefore be subdivided into a
number of unique drive partitions in order to make use of all of its space.
Because of the differences in the way that drive sizes are calculated, the size reported by the operating
system may differ from that marked on the hard drive or listed in the computer specification. Drive size
calculations by drive manufacturers are bytes to the base 10 while calculations by Microsoft are bytes
to the base 2.

Electrostatic Discharge Information
A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive
devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic
device exposed to electrostatic discharge (ESD) may not appear to be affected at all and can work
perfectly throughout a normal cycle. The device may function normally for a while, but it has been
degraded in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge
contains enough power to alter device parameters or melt silicon junctions.
Generating Static
The following table shows that:
●
Different activities generate different amounts of static electricity.
●
Static electricity increases as humidity decreases.

of sensitivity. The following packaging and grounding precautions are necessary to prevent damage to
electric components and accessories.
●
To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.
●
Protect all electrostatic parts and assemblies with conductive or approved containers or packaging.
●
Keep electrostatic sensitive parts in their containers until they arrive at static-free stations.
●
Place items on a grounded surface before removing them from their container.
●
Always be properly grounded when touching a sensitive component or assembly.
Electrostatic Discharge Information
53
●
Avoid contact with pins, leads, or circuitry.
●
Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive
foam.
Personal Grounding Methods and Equipment
Use the following equipment to prevent static electricity damage to equipment:
●
Wrist straps are flexible straps with a maximum of one-megohm ± 10% resistance in the ground
cords. To provide proper ground, a strap must be worn snug against bare skin. The ground cord
must be connected and fit snugly into the banana plug connector on the grounding mat or
workstation.
●
Heel straps/Toe straps/Boot straps can be used at standing workstations and are compatible
with most types of shoes or boots. On conductive floors or dissipative floor mats, use them on both

Operating Guidelines
To prevent overheating and to help prolong the life of the computer:
●
Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.
●
Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all vented
sides of the computer and above the monitor to permit the required airflow.
●
Never restrict the airflow into the computer by blocking any vents or air intakes. Do not place the
keyboard, with the keyboard feet down, directly against the front of the desktop unit as this also
restricts airflow.
●
Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other foreign
matter can block the vents and limit the airflow. Be sure to unplug the computer before cleaning
the air vents.
●
Never operate the computer with the cover or side panel removed.
●
Do not stack computers on top of each other or place computers so near each other that they are
subject to each other’s re-circulated or preheated air.
●
If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must
be provided on the enclosure, and the same operating guidelines listed above will still apply.
●
Keep liquids away from the computer and keyboard.
●
Never cover the ventilation slots on the monitor with any type of material.
●
Install or enable power management functions of the operating system or other software, including
sleep states.

●
Keep cables away from major heat sources like the heatsink.
●
Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these
are not designed to take excessive pressure on them.
●
Keep cables clear of sliding or moveable parts to prevent them from being cut or crimped when
the parts are moved.
●
When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases may damage the
wires.
●
Some flat ribbon cables come prefolded. Never change the folds on these 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.
When removing the power supply power cables from the P1 or P3 connectors 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 (1).

Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2SDRAM) dual inline memory modules (DIMMs).
The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 8 GB of memory configured in a highperforming dual channel mode.
For proper system operation, the DDR2-SDRAM DIMMs must be:
●
industry-standard 240-pin
●
unbuffered, PC2-5300 667 MHz-compliant or PC2-6400 800 MHz-compliant
●
1.8 volt DDR2-SDRAM DIMMs
The DDR2-SDRAM DIMMs must also:
●
support CAS latency 5 DDR2 667 Mhz (5-5-5 timing), CAS latency 5 DDR2 800 Mhz (5-5-5 timing),
and CAS latency 6 DDR2 800 Mhz (6-6-6 timing)
●
contain the mandatory JEDEC SPD information
In addition, the computer supports:
●
512Mbit and 1Gbit non-ECC memory technologies
●
single-sided and double-sided DIMMs
●
DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not
supported
NOTE:
The system will not operate properly if you install unsupported DIMMs.
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in memory channel A.
Sockets XMM3 and XMM4 operate in memory channel B.

NOTE:
A DIMM must occupy the XMM1 socket.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.
●
The system will operate in single channel mode if the DIMM sockets are populated in one channel
only.
●
The system will operate in a higher-performing dual channel mode if the total memory capacity of
the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B. The
technology and device width can vary between the channels. For example, if Channel A is
populated with two 512MB DIMMs and Channel B is populated with one 1GB DIMM, the system
will operate in dual channel mode.
●
The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is not
equal to the total memory capacity of the DIMMs in Channel B. In flex mode, the channel populated
with the least amount of memory describes the total amount of memory assigned to dual channel
and the remainder is assigned to single channel. For optimal speed, the channels should be
balanced so that the largest amount of memory is spread between the two channels. If one channel
will have more memory than the other, the larger amount should be assigned to Channel A. For
example, if you are populating the sockets with one 1GB DIMM, and three 512MB DIMMs, Channel
A should be populated with the 1GB DIMM and one 512MB DIMM, and Channel B should be
populated with the two 512MB DIMMs. With this configuration, 2GB will run as dual channel and
512MB will run as single channel.
●
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
CAUTION: The memory module sockets have gold metal contacts. When upgrading the memory, it
is important to use memory modules with gold metal contacts to prevent corrosion and/or oxidation
resulting from having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before
beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object. Refer to Electrostatic Discharge Information on page 53 for more information.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.
1.
Prepare the computer for disassembly (Preparation for Disassembly on page 61).

3.
Open both latches of the memory module socket (1), and insert the memory module into the socket
(2).
NOTE: A memory module can be installed in only one way. Match the notch on the module with
the tab on the memory socket. A DIMM must occupy the black XMM1 socket.
NOTE: For maximum performance, populate the sockets so that the memory capacity is spread
as equally as possible between Channel A and Channel B.
4.
Push the DIMM module down firmly into the socket, ensuring that the module is fully inserted and
properly seated. The DIMM must be pushed all the way down into the socket and sit evenly in the
socket to avoid memory corruption. Make sure the latches are in the closed position (3).

120 Chapter 8 Removal and Replacement Procedures Small Form Factor (SFF) Chassis
Installing Additional Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2SDRAM) dual inline memory modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 8 GB of memory configured in a highperforming dual channel mode.
DDR2-SDRAM DIMMs
For proper system operation, the DDR2-SDRAM DIMMs must be:
●
industry-standard 240-pin
●
unbuffered PC2-5300 667 MHz-compliant or PC2-6400 800 MHz-compliant
●
1.8 volt DDR2-SDRAM DIMMs
The DDR2-SDRAM DIMMs must also:
●
support CAS latency 5 DDR2 667 Mhz (5-5-5 timing), CAS latency 5 DDR2 800 Mhz (5-5-5 timing),
and CAS latency 6 DDR2 800 Mhz (6-6-6 timing)
●
contain the mandatory JEDEC SPD information
In addition, the computer supports:
●
512Mbit and 1Gbit non-ECC memory technologies
●
single-sided and double-sided DIMMs
●
DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not
supported
NOTE:
The system will not operate properly if you install unsupported DIMMs.
Installing Additional Memory 121
Populating DIMM Sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in memory channel A.
Sockets XMM3 and XMM4 operate in memory channel B.
Item

White
3
DIMM socket XMM3, Channel B
(populate second)
Black
4
DIMM socket XMM4, Channel B
White
NOTE: A DIMM must occupy the XMM1 socket.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.
●
The system will operate in single channel mode if the DIMM sockets are populated in one channel
only.
●
The system will operate in a higher-performing dual channel mode if the total memory capacity of
the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B. The
technology and device width can vary between the channels. For example, if Channel A is
populated with two 512MB DIMMs and Channel B is populated with one 1GB DIMM, the system
will operate in dual channel mode.
●
The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is not
equal to the total memory capacity of the DIMMs in Channel B. In flex mode, the channel populated
with the least amount of memory describes the total amount of memory assigned to dual channel
and the remainder is assigned to single channel. For optimal speed, the channels should be
balanced so that the largest amount of memory is spread between the two channels. If one channel
122 Chapter 8 Removal and Replacement Procedures Small Form Factor (SFF) Chassis
will have more memory than the other, the larger amount should be assigned to Channel A. For
example, if you are populating the sockets with one 1GB DIMM, and three 512MB DIMMs, Channel
A should be populated with the 1GB DIMM and one 512MB DIMM, and Channel B should be
populated with the two 512MB DIMMs. With this configuration, 2GB will run as dual channel and
512MB will run as single channel.
●
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
Installing DIMMs
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power to
drain before adding or removing memory modules. Regardless of the power-on state, voltage is always
supplied to the memory modules as long as the computer is plugged into an active AC outlet. Adding
or removing memory modules while voltage is present may cause irreparable damage to the memory
modules or system board. If you see an LED light on the system board, voltage is still present.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is
important to use memory modules with gold-plated metal contacts to prevent corrosion and/or oxidation
resulting from having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before
beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object. For more information, refer to Electrostatic Discharge Information on page 53.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.
1.
Prepare the computer for disassembly (Preparation for Disassembly on page 110).
2.
Remove the access panel (Computer Access Panel on page 116).
3.
Rotate up the external drive bay housing and the power supply to access the memory module
sockets on the system board.
WARNING! To reduce risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.
Installing Additional Memory 123
4.
Open both latches of the memory module socket (1), and insert the memory module into the socket
(2).
NOTE: A memory module can be installed in only one way. Match the notch on the module with
the tab on the memory socket.
A DIMM must occupy the black XMM1 socket.
For maximum performance, populate the sockets so that the memory capacity is spread as equally
as possible between Channel A and Channel B. Refer to Populating DIMM Sockets on page 122
for more information.
5.
Push the module down into the socket, ensuring that the module is fully inserted and properly
seated. Make sure the latches are in the closed position (3).
6.
Repeat steps 4 and 5 to install any additional modules.

Cable Management
The Small Form Factor chassis is very compact and proper routing of the internal cables is critical to
the computer operation. Follow good cable management practices when working inside the computer.
●
Keep cables away from major heat sources like the heatsink.
●
Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these
are not designed to take excessive pressure on them.
●
Keep cables clear of movable or rotating parts like the power supply and drive cage to prevent
them from being cut or crimped when the component is lowered into its normal position.
●
When folding a flat ribbon cable, never fold to a sharp crease.
●
Some flat ribbon cables come prefolded. Never change the folds on these 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.
When removing the power supply power cables from the P1 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 (1).
2.
Grasp the cable end of the connector and pull it straight up (2).
CAUTION: Always pull the connector - NEVER pull on the cable. Pulling on the cable could

Power Cord Set Requirements
The power supplies on some computers have external power switches. The voltage select switch feature
on the computer permits it to operate from any line voltage between 100-120 or 220-240 volts AC. Power
supplies on those computers that do not have external power switches are equipped with internal
switches that sense the incoming voltage and automatically switch to the proper voltage.
The power cord set received with the computer meets the requirements for use in the country where
you purchased the equipment.
Power cord sets for use in other countries must meet the requirements of the country where you use
the computer.
General Requirements
The requirements listed below are applicable to all countries:
1.
The power cord must be approved by an acceptable accredited agency responsible for evaluation
in the country where the power cord set will be installed.
2.
The power cord set must have a minimum current capacity of 10A (7A Japan only) and a nominal
voltage rating of 125 or 250 volts AC, as required by each country’s power system.
3.
The diameter of the wire must be a minimum of 0.75 mm2 or 18AWG, and the length of the cord
must be between 1.8 m (6 feet) and 3.6 m (12 feet).
The power cord should be routed so that it is not likely to be walked on or pinched by items placed upon
it or against it. Particular attention should be paid to the plug, electrical outlet, and the point where the
cord exits from the product.
WARNING! Do not operate this product with a damaged power cord set. If the power cord set is
damaged in any manner, replace it immediately.
Japanese Power Cord Requirements
For use in Japan, use only the power cord received with this product.
CAUTION: Do not use the power cord received with this product on any other products.

POST Error Messages
This appendix lists the error codes, error messages, and the various indicator light and audible
sequences that you may encounter during Power-On Self-Test (POST) or computer restart, the probable
source of the problem, and steps you can take to resolve the error condition.
POST Message Disabled suppresses most system messages during POST, such as memory count
and non-error text messages. If a POST error occurs, the screen will display the error message. To
manually switch to the POST Messages Enabled mode during POST, press any key (except F10 or
F12). The default mode is POST Message Disabled.
The speed at which the computer loads the operating system and the extent to which it is tested are
determined by the POST mode selection.
Quick Boot is a fast startup process that does not run all of the system level tests, such as the memory
test. Full Boot runs all of the ROM-based system tests and takes longer to complete.
Full Boot may also be enabled to run every 1 to 30 days on a regularly scheduled basis. To establish
the schedule, reconfigure the computer to the Full Boot Every x Days mode, using Computer Setup.
NOTE:
For more information on Computer Setup, see the Computer Setup (F10) Utility Guide.
180 Appendix C POST Error Messages
POST Numeric Codes and Text Messages
This section covers those POST errors that have numeric codes associated with them. The section also
includes some text messages that may be encountered during POST.
NOTE:
The computer will beep once after a POST text message is displayed on the screen.

Password Security and Resetting
CMOS
This computer supports security password features, which can be established through the Computer
Setup Utilities menu.
This computer supports two security password features that are established through the Computer
Setup Utilities menu: setup password and power-on password. When you establish only a setup
password, any user can access all the information on the computer except Computer Setup. When you
establish only a power-on password, the power-on password is required to access Computer Setup and
any other information on the computer. When you establish both passwords, only the setup password
will give you access to Computer Setup.
When both passwords are set, the setup password can also be used in place of the power-on password
as an override to log in to the computer. This is a useful feature for a network administrator.
If you forget the password for the computer, you can clear that password so you can gain access to the
information on the computer by resetting the password jumper.
CAUTION: Pushing the CMOS button will reset CMOS values to factory defaults. It is important to
back up the computer CMOS settings before resetting them in case they are needed later. Back up is
easily done through Computer Setup. See the Computer Setup (F10) Utility Guide for information on
backing up the CMOS settings.

Solving Hardware Installation Problems
You may need to reconfigure the computer when you add or remove hardware, such as an additional
drive or expansion card. If you install a plug and play device, Windows automatically recognizes the
device and configures the computer. If you install a non–plug and play device, you must reconfigure the
computer after completing installation of the new hardware. In Windows, use the Add Hardware
Wizard and follow the instructions that appear on the screen.
WARNING! When the computer is plugged into an AC power source, voltage is always applied to the
system board. To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure
to disconnect the power cord from the wall outlet and allow the internal system components to cool
before touching.
Look for the LED on the system board. If the LED is illuminated, the system still has power. Power off
the computer and remove the power cord before proceeding.

Solving Memory Problems
If you encounter memory problems, some common causes and solutions are listed in the following table.
CAUTION: Power may still be supplied to the DIMMs when the computer is turned off (depending on
the Management Engine (ME) settings). To avoid damage to the DIMMs or the system board, you must
unplug the computer power cord before attempting to reseat, install, or remove a DIMM module.
For those systems that support ECC memory, HP does not support mixing ECC and non-ECC memory.
Otherwise, the computer will not boot the operating system.
NOTE: The memory count will be affected by configurations with the Management Engine (ME)
enabled. The ME uses 8MB of system memory in single channel mode or 16MB of memory in dualchannel mode to download, decompress, and execute the ME firmware for Out-of-Band (OOB), thirdparty data storage, and other management functions.
Table E-13 Solving Memory Problems
