Ensuring proper ventilation

Proper ventilation for the system is important for computer operation. To be sure that there is adequate ventilation:
Operate the computer on a sturdy, level surface.
Provide at least 15.24 cm (6.00 in) of clearance at the front and back of the computer. (This is the minimum distance for all computer models.)
Be sure that the ambient air temperature surrounding the computer falls within the specied limits (see
Environmental specications on page 11).
For cabinet installation, ensure adequate cabinet ventilation and ensure that the ambient temperature within the cabinet does not exceed specied limits.
Never restrict the incoming or outgoing airow of the computer by blocking any vents or air intakes.

Adding monitors

Planning for additional monitors

Entry model
The HP Z2 Mini G3 Entry system supports up to three simultaneous displays running on the Intel integrated GPU. Each display is capable of resolutions up to 4096 × 2160 @ 60 Hz.
It is also possible to drive a panel at a resolution of 5120 × 2880 @60 Hz by using two of the DisplayPort 1.2 outputs together. The panel must support this method of achieving this resolution for this to be possible.
Performance model
The HP Z2 Mini G3 Performance model is capable of operating in two distinct modes: NVIDIA GPU–only mode or NVIDIA GPU + Intel GPU mode. The NVIDIA GPU–only mode oers the best performance, while the NVIDIA GPU + Intel GPU mode allows the system to drive an additional two displays.
NVIDIA GPU–only mode:
The default conguration.
Oers the best performance because every DisplayPort 1.2 port is driven directly by the NVIDIA Quadro GPU.
Capable of driving up to four independent displays at a maximum resolution of 4096×2160 @ 60 Hz or two independent displays at a maximum resolution of 5120×2880 @ 60 Hz by combining DisplayPort outputs. The display must support this method of achieving this resolution.
NVIDIA GPU + Intel GPU mode:
The NVIDIA GPU can support a maximum of four independent displays. To support an additional two displays, the system can be congured to simultaneously use both the NVIDIA Quadro GPU and the Intel integrated GPU.
This mode is congured in the system BIOS.
1. Press the power button on the system, and then repeatedly press the F10 key until you’ve reached the system BIOS GUI.
2. Navigate to the Advanced tab.
3. Select Built-In Device Options.
4. Select Enable Intel graphics on DisplayPort port #4.
5. Press Enter to accept the prompt notifying you that the Intel GPU will be output on DisplayPort #4.
6. Press F10 to save your changes and exit.
This mode is capable of driving up to six independent displays.
Because the system has only four DisplayPort 1.2 ports, two of the DisplayPort 1.2 ports must each drive two displays in a daisy-chained conguration. This is accomplished by using DisplayPort
14 Chapter 2 System management
Performance is dependent upon which GPU is running the application. For the best performance of a particular application, ensure that the application is running on the NVIDIA Quadro GPU.
Planning process
The process for adding monitors depends on the type and number of monitors you add.
Use the following process to plan for adding more monitors:
1. Assess your monitor needs.
a. Determine how many monitors you require.
b. Determine the kind of graphics performance you want. For maximum performance, ensure that
1.2 Multi-Stream Transport (MST) and requires displays which support MST or DisplayPort hubs capable of MST.
To achieve a six-display conguration, one of the daisy chains must be driven by the Intel GPU on DisplayPort #4. Refer to Performance model on page 4 to identify specic DisplayPorts. The other daisy chain can be driven by the NVIDIA Quadro GPU on any of the remaining DisplayPort 1.2 ports.
Each DisplayPort 1.2 output on the system is capable of driving a display at a resolution of 4096 × 2160 @ 60 Hz. When two displays are daisy-chained together from a single DisplayPort 1.2 port, each display in the daisy chain is bandwidth-limited to a maximum resolution of 2560 × 1600 @ 60 Hz.
your display is driven by the NVIDIA Quadro GPU.
c. Note the type of graphics connector used by each monitor. HP provides graphics cards with
DisplayPort (DP) and DVI interfaces, but you can use adapters and third-party cards for other graphics formats, including DVI-I, HDMI, or VGA.
TIP: Some adapters for older legacy hardware may cost more than others. You may want to
compare the cost of acquiring adapters with the cost of getting a newer monitor that doesn't need adapters.
2. Install drivers and congure resolutions.
a. Be sure that you have the correct drivers for the card. See http://www.hp.com for HP-qualied
drivers.
b. Congure each monitor’s resolution, orientation, and placement through Windows Display
Settings. For details, refer to Windows Help or to http://www.microsoft.com.
c.
For monitor setup in Linux, you can often use the settings tool for the graphics cards (e.g., NVIDIA nvidia-settings). In some recent Linux releases, the window manager system (e.g., Gnome 3) preferences must also be modied.
TIP: To simplify troubleshooting of possible problems, enable the monitors one at a time: enable the
rst monitor and be sure that it works properly before enabling the next monitor.

Identifying monitor connection requirements

Graphics card with DisplayPort output —The system has four DisplayPort 1.2 outputs. You can connect a
monitor to each connector. Use the proper adapters, if required.
Connecting and conguring monitors
1. Connect the monitor cable adapters (if required) to the computer, then connect the appropriate monitor
cables to the adapters or directly to the graphics card.
2. Connect the other ends of the monitor cables to the monitors.
3. Connect one end of the monitor power cord to the monitor and the other end to an AC outlet.
4. Congure the monitor. For details, refer to Microsoft Help or to http://www.microsoft.com.

By specifying your models, operating system, and language, you can quickly locate, sort, and select the SoftPaqs you need, as well as create your own Driver Pack for OS deployment. For more information, go to http://www8.hp.com/us/en/ads/clientmanagement/
drivers-bios.html#softpaq-download-mng.

HP System Software Manager

HP System Software Manager (SSM) is a utility that is available on Windows computers. It enables you to update system-level software on multiple systems simultaneously. When executed on a PC client system, SSM detects hardware and software versions and then updates the software from a central repository, known as a le store. Driver versions supported by SSM are noted with a special icon in the software, on the driver download website, and on the Support Software CD.
Desktop management 31
To download the utility or to obtain more information about SSM, go to http://www8.hp.com/us/en/ads/
clientmanagement/drivers-bios.html#system-sw-mng.

ROM Flash

BIOS settings are stored on a programmable ash ROM. By establishing a setup password in Computer Setup (F10) Utility, you can protect unauthorized users from modifying the BIOS settings. This function is important to ensure the operating integrity of the computer.
To upgrade the BIOS, download the latest SoftPaq images from http://www.hp.com/support/
workstation_swdrivers.
Remote ROM Flash
Remote ROM Flash allows system administrators to safely upgrade the ROM on remote HP computers from a centralized network management console, resulting in a consistent deployment of, and greater control over, HP PC ROM images over the network.
To use Remote ROM Flash, the computer must be turned on, or turned on using Remote Wakeup.
For more information about Remote ROM Flash and HPQFlash, see the HP Client Manager Software or System Software Manager sections at http://www.hp.com/go/ssm.
HPBiosUpdRec
The HPBiosUpdRec utility is used to locally update or restore the system ROM on PCs using a Windows operating system. For more information about HPBiosUpdRec, go to http://www.hp.com/go/ssm, and enter the name of the computer.

FailSafe Boot Block

FailSafe Boot Block enables BIOS recovery in the unlikely event of a ROM ash failure.
For example, if a power failure occurs during a ROM upgrade, Boot Block uses a ash-protected section of the ROM to verify a valid system ROM ash when power is restored to the computer.
If the system ROM is valid, the computer starts normally. If the system ROM fails the validation check, FailSafe Boot Block provides enough support to start the computer from a BIOS image CD that has been created from a SoftPaq. The BIOS image CD programs the system ROM with a valid image.
When Boot Block detects an invalid system ROM, the computer power light blinks red eight times and the computer beeps eight times; then the computer pauses for two seconds. On some models, a Boot Block recovery mode message appears.
In preparation for system recovery, use the BIOS CD media le in the SoftPaq to create a BIOS image CD or USB ash drive.
32 Chapter 2 System management
Recovering the computer from Boot Block Recovery mode
To recover the computer after it enters Boot Block recovery mode:
1. Remove any media such as USB ash drives or discs in the optical drives.
2. Insert a BIOS image CD into the DVD drive. You can also use USB media such as an HP DriveKey.
3. Turn the computer o, and then turn it on.
If no BIOS image CD or USB media is found, you are prompted to insert one and restart the computer.
If a setup password has been established, the Caps Lock light turns on and you are prompted for the password.
4. Enter the setup password.
If the computer starts from the boot media and successfully reprograms the ROM, three keyboard lights turn on and a rising-tone series of beeps signals successful recovery.
5. Remove the boot media and turn o the computer.
6. Restart the computer.

Computer security

This section provides information about providing system security through asset tracking, password security, hard drive locking, and chassis locks.
Asset tracking
Asset tracking features provide data that can be managed using HP Systems Insight Manager (HP SIM), HP Console Management Controller (CMC), or other systems-management applications.
Seamless, automatic integration between asset tracking features and these products enables you to choose the management tool that is best suited to the environment and to leverage investments in existing tools.
HP also oers several solutions for controlling access to valuable components and information:
You can manage security settings as follows:
For more information about Computer Setup (F10) Utility, see Computer Setup (F10) Utilities on page 18.
The following Computer Setup (F10) Utility features let you manage computer security.
Capability for protecting valuable data assets by disabling parallel, serial, or USB ports, or by disabling removable-media boot capability
Memory Change alerts, which can be forwarded to system management applications to deliver proactive notication of tampering with a computer’s internal components

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
Feature
Purpose
Removable Media Boot Control Prevents booting from removable media drives
USB Interface Control Prevents transfer of data through the integrated USB interface
Desktop management 33
Feature Purpose

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.
DriveLock is for HP customers for whom data security is the paramount concern. For such customers, the cost of a hard drive and the loss of the data stored on it is inconsequential when compared to the damage that could result from unauthorized access to its contents.
To balance this level of security with the need to address the issue of a forgotten password, the HP implementation of DriveLock employs a two-password security scheme. One password is intended to be set and used by a system administrator, while the other is typically set and used by the user.
No "back door" can be used to unlock the drive if both passwords are lost. Therefore, DriveLock is most safely used when the data contained on the hard drive is replicated on a corporate information system or is regularly backed up.
Prevents use of the computer until the password is entered (applies to initial system startup and restarts)
Prevents reconguration of the computer (through Computer Setup (F10) Utility) until the password is entered
If both DriveLock passwords are lost, the hard drive is inaccessible. For users who do not t the previously dened customer prole, this outcome might not be acceptable. For users who t this prole, the outcome might be a tolerable risk, given the nature of the data stored on the hard drive.
DriveLock applications
The most practical use of DriveLock is in a corporate environment. The system administrator would be responsible for conguring the hard drive, which involves setting the DriveLock master password and a temporary user password. If the system administrator forgets the user password or if the equipment is passed on to another employee, the master password can be used to reset the user password and restore access to the hard drive.
HP recommends that corporate system administrators who enable DriveLock also establish a corporate policy for setting and maintaining master passwords. This precaution will prevent loss of information if an employee sets both DriveLock passwords before leaving the company. In such a scenario, the hard drive is inaccessible and must be replaced. Likewise, by not setting a master password, system administrators might nd themselves locked out of a hard drive and unable to perform routine checks for unauthorized software, other asset control functions, and support.
For users with less stringent security requirements, HP does not recommend enabling DriveLock. Users in this category include personal users, or users who do not maintain sensitive data on their hard drives as a common practice. For these users, the potential loss of a hard drive resulting from forgetting both passwords is much greater than the value of the data DriveLock protects.
Access to Computer Setup (F10) Utility and DriveLock can be restricted through the setup password. By specifying a setup password and not giving it to users, system administrators can restrict users from enabling DriveLock.
34 Chapter 2 System management
Using DriveLock
When hard drives that support the ATA security command set are detected, DriveLock appears under the Security menu in the Computer Setup (F10) Utility menu. You are presented with options to set the master password and to enable DriveLock. You must provide a user password to enable DriveLock. Because the initial
conguration of DriveLock is typically performed by a system administrator, a master password should be set rst.
HP encourages system administrators to set a master password whether they plan to enable DriveLock or not. This gives the administrator the ability to modify DriveLock settings if the drive is locked in the future. After the master password is set, the system administrator can enable DriveLock or leave it disabled.
If a locked hard drive is present, POST requires a password to unlock the device. If a power-on password is set and it matches the device’s user password, POST does not prompt the user to re-enter the password. Otherwise, the user is prompted to enter a DriveLock password.
For a cold start, use the master or user password. For a warm start, enter the same password used to unlock the drive during the preceding cold start.
Users have two attempts to enter a correct password. During cold start, if neither attempt succeeds, POST continues but the drive remains inaccessible. During a warm-start or restart from Windows, if neither attempt succeeds, POST halts and the user is instructed to cycle power.
Enabling DriveLock
To enable and set the DriveLock user password:
1. Turn on or restart the computer.
2. As soon as the computer is turned on, repeatedly press the F10 key until Computer Setup (F10) Utility
starts.
If you do not press F10 at the appropriate time, you must restart the computer, and then repeatedly press F10 to access the utility.
3. Select Security > DriveLock Security.
4. For each DriveLock-capable drive, select the drive by pressing Enter.
5. Under Enable/Disable DriveLock options, select Enable, and then press Enter to enable DriveLock for
that drive.
NOTE: To set the DriveLock master password, select Master.
CAUTION: If you forget the DriveLock password, the drive is inaccessible.
6. Enter a new user password (1 to 32 characters long), and then press Enter to accept.
7. Enter the password again in the Enter New Password Again eld. If you forget this password, the drive
is permanently disabled.
8. Select Main > Save Changes and Exit. Press Enter to accept the changes. After you press Enter, the
computer performs a cold start before invoking the DriveLock function.
When the computer starts, you are prompted to enter the DriveLock password for each DriveLock­capable drive for which you have set a password. You have two attempts to enter the password correctly. If the password is not entered correctly, the computer attempts to start anyway. However, the boot process most likely fails because data from a locked drive cannot be accessed.
In a single-drive computer, when DriveLock is enabled, the computer might not be able to boot to the operating system, and might try to boot from the network or from another storage device (depending
Desktop management 35
on the boot ordering options). Regardless of the outcome of the start attempts, the locked drive remains inaccessible without the DriveLock password.
In a two-drive computer that has a boot drive and a data drive, you can apply the DriveLock feature to the data drive only. In this case, the computer can always start, but the data drive is accessible only when the DriveLock password is entered.
Cold starts require that you enter DriveLock passwords. However, DriveLock passwords are also required for warm starts. For example, if you boot to DOS and press Ctrl+Alt+Del, you must enter the DriveLock password before the computer completes the next start cycle. This warm-start behavior is consistent with the DriveLock feature.
Password security
The power-on password prevents unauthorized access to applications or data when the computer is turned on or restarted. The setup password specically prevents unauthorized access to the Computer Setup (F10) Utility and can also be used as an override to the power-on password. An administrator can enter the setup password at the prompt for the power-on password and gain access to the computer.
You can establish a network-wide setup password to enable the system administrator to log in to all network systems to perform maintenance without needing to know the power-on password.
Establishing a setup password using Computer Setup (F10) Utility
Establishing a setup password through the Computer Setup (F10) Utility prevents reconguration of the computer (through the use of Computer Setup (F10) Utility) until the password is entered.

4. Before exiting, select Main > Save Changes and Exit.
Establishing a power-on password using computer setup
Establishing a power-on password through Computer Setup (F10) Utility prevents access to the computer when power is connected, unless you specify the password. When a power-on password is set, Computer Setup (F10) Utility presents Password Options in the Security menu. The password options include Network Server Mode and Password Prompt on Warm Boot.
When Password Prompt on Warm Boot is enabled, you must enter the password. The password must also be entered each time the computer is restarted.
To establish a power-on password through the Computer (F10) menu:
1. Turn on or restart the computer.
2. As soon as the computer is turned on, repeatedly press the F10 key until you enter Computer Setup
(F10) Utility.
If you do not press F10 at the appropriate time, you must restart the computer, and then repeatedly press F10 to access the utility.

Battery

The battery that comes with the computer provides power to the real-time clock and has a minimum lifetime of about three years. Observe the following warning and caution when replacing the battery.
CAUTION: Before removing the battery, back up the CMOS settings in case they are lost when the battery is
removed. To back up the CMOS settings, select the Save to Removable Storage option in Computer Setup (F10) Utility.
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 computer. 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 heat sink. (Some air ow guides have a cable guide that lets you route cables safely around the heat sink.)
Do not jam cables on top of expansion cards or SODIMMs. Circuit cards and SODIMMs are not designed to take excessive pressure.
Component replacement guidelines 49
Keep cables clear of movable or rotating parts (such as fans, power supply, and drive cage) to prevent them from being cut or crimped when the component is lowered into its normal position and during normal operation.
When folding a at ribbon cable, never fold to a sharp crease. Sharp creases may damage the wires.
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. Press down 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 on the connector — NEVER pull on the cable. Pulling on the cable could damage
the cable and result in a failed power supply.

CPU (processor) and CPU heat sink

CAUTION: Observe the following cautions when removing or replacing the heat sink:
— When removing the heat sink, loosen all screws a little at a time to be sure that the CPU remains level. Do not fully loosen one screw, and then move on to the next.
— Do not overtighten the heat sink screws. Overtightening can strip the threads in the chassis.
CAUTION: Observe the following cautions when removing or replacing the CPU.
— Internal components might be powered even when the computer is o. To prevent damage, disconnect the computer power cord before you remove or install a component.
— 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 authorized 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.

To verify the type, size, and capacity of the storage devices installed in the computer, run Computer Setup (F10) Utility.
The computer supports 2.5" SFF SATA hard drives or solid-state drives and M.2 Key M NVMe PCIe solid­state drives
No cable adapters are required for any hard drives. The cables necessary for all hard drive congurations are included in the base system and automatically "blind mate" or "direct connect" to the drive(s) when installed.
Removing hard drive cables
To properly remove a hard drive cable, prior to removing the hard drive, pull the SATA connector from the hard drive using the blue pull tab. Try not to pull the cable out of the system board connector.
NOTE: There is an identifying mark on the system board that indicates into which side to insert the blue tab
on the cable.
NOTE: Make sure the hard drive cable is not twisted.
Handling hard drives
CAUTION: Take proper precautions when handling hard drives to prevent loss of work and damage to the
computer or drive.
Do not remove hard drives from the shipping package for storage. Keep hard drives in their protective packaging until they are mounted in the computer.
Always shut down the operating system, turn o the power, and unplug the power cord. Never remove a drive while the computer is on or in standby mode.
Before handling a drive, be sure that you discharge static electricity. While handling a drive, avoid touching the connector.
Handle a drive carefully. Do not drop it from any height.
Do not use excessive force when inserting a drive.
Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic elds such as monitors or speakers.
If you must mail a drive, use a bubble-pack mailer or other protective packaging and label the package “Fragile: Handle With Care.”

Memory

Supported SODIMM congurations
The computer has 2 SODIMM slots and supports up to 32 GB ECC or non-ECC unbuered DDR4 2133 MHz memory.
NOTE: Mirroring and SODIMM sparing are not supported.
Two SODIMM slots
Maximum capacity: 32 GB
Error checking and correcting (ECC) and non-ECC SODIMMs only.
BIOS errors and warnings
The BIOS generates warnings/errors on invalid memory congurations:
If the BIOS can nd a valid memory conguration by disabling plugged-in memory, it does so and reports a warning during POST. The computer can still be started. The warning will indicate the location of the failed SODIMM on the system board.
If there is no way for the BIOS to obtain a valid memory conguration by disabling plugged-in memory, the BIOS halts with a diagnostics 2006 code for memory error (three beeps and two blinks).
SODIMM installation guidelines
Install only HP-approved DDR4 SODIMMs
CAUTION: HP ships only SODIMMs that are electrically and thermally compatible with this computer.
Because third-party SODIMMs might not be electrically or thermally compatible, they are not supported by HP.
For ECC SODIMMs, use only industry-standard ECC unbuered SODIMMs. Go to http://www.hp.com/go/
quickspecs to nd which SODIMMs are compatible with the computer.
Do not intermix non-ECC memory SODIMMs with ECC memory SODIMMs.
CAUTION: SODIMMs and their sockets are keyed for proper installation. To prevent socket or SODIMM
damage, align these guides properly when installing SODIMMs.

Using HP PC Hardware Diagnostics (UEFI)

HP PC Hardware Diagnostics is a Unied Extensible Firmware Interface (UEFI) that allows you to run diagnostic tests to determine whether the computer hardware is functioning properly. The tool runs outside the operating system so that it can isolate hardware failures from issues that are caused by the operating system or other software components.
When HP PC Hardware Diagnostics (UEFI) detects a failure that requires hardware replacement, a 24-digit Failure ID code is generated. This ID code can then be provided to support to help determine how to correct the problem.
NOTE: To start diagnostics on a convertible computer, your computer must be in notebook mode and you
must use the keyboard attached.
To start HP PC Hardware Diagnostics (UEFI), follow these steps:
1. Turn on or restart the computer, and quickly press esc.
2. Press f2.
The BIOS searches three places for the diagnostic tools, in the following order:
a. Connected USB drive
NOTE: To download the HP PC Hardware Diagnostics (UEFI) tool to a USB drive, see Downloading
HP PC Hardware Diagnostics (UEFI) to a USB device on page 71.
b. Hard drive
c. BIOS
3. When the diagnostic tool opens, select the type of diagnostic test you want to run, and then follow the
on-screen instructions.
NOTE: If you need to stop a diagnostic test, press esc.

POST error messages and diagnostic front panel LEDs and audible codes

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 non­error 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, F11, 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, recongure the computer to the Full Boot Every x Days mode, using Computer Setup.
NOTE: For more information on Computer Setup, see Computer Setup (F10) Utilities on page 18.

Interpreting system validation diagnostic front panel lights and audible codes

During the system validation phase that occurs at system startup, the BIOS validates the functionality of the following subsystems and conditions:
AC adapter
System board power
Processor failure
BIOS corruption
Memory failure
Graphics failure
System board failure
BIOS authentication failure
If an error is detected, specic patterns of long and short blinks, accompanied by long and short beeps (where applicable) are used to identify the error. These patterns will make up a two part code:
Major – the category of the error
Minor – the specic error within the category
NOTE: Single beep/blink codes are not used.
Number of long beeps/blinks Error category
1 Not used
2 BIOS
3 Hardware
4 Thermal
5 System board
Patterns of blink/beep codes are determined by using the following parameters:
1 second pause occurs after the last major blink.
2 second pause occurs after the last minor blink.
Beep error code sequences occur for the rst 5 iterations of the pattern and then stop.
Blink error code sequences continue until the computer is unplugged or the power button is pressed.
NOTE: Not all diagnostic lights and audible codes are available on all models.

5 Conguring password security and
resetting CMOS
This chapter describes how to congure password security and to reset CMOS.
Preparing to congure passwords
Computer Setup (F10) Utility enables you to create setup and power-on passwords.
There are three possibilities for setting passwords:
Dene an administrator password only. You will need the password to enter Computer Setup (F10) Utility, but you will not need a password to start the computer.
Dene a power-on password only. This password lets you start the computer or enter the setup utility.
Dene both. In this case, the administrator password lets you start the computer and enter the setup utility. The power-on password starts the computer but does not let you enter the setup utility,
After you create both passwords, you can use the administrator password in place of the power-on password as an override to log into the computer (a useful feature for a network administrator).
NOTE: You can only clear the passwords with the password jumper. Clearing CMOS does not clear the
passwords.
CAUTION: Before pressing the Clear CMOS button, back up your computer CMOS settings.
Pressing the Clear CMOS button resets CMOS values to factory defaults and erases customized information, including asset numbers and special settings.
To back up the CMOS settings, run Computer Setup (F10) Utility and select Main > Replicated Setup > Backup
current settings to USB device.

Resetting the password jumper

CAUTION: Stringent security is a mode where there is no physical bypass of the password function. If
enabled, removing the password jumper will be ignored. To enable this mode, change the security setting Clear Password Jumper in Password Policies to Ignore.
If you lose or forget the password when in stringent security mode, the system can only be reset by System Management Command. This is a way for HP Service and Support to provide a secure method to access the BIOS and command a password reset for a specically identied unit under the direction of the owner. This scenario may not be covered under warranty.
To prevent needing a customer service event to restore access to the system, record your congured administrator and power-on passwords in a safe place away from your computer.
To disable the power-on or administrator password features, or to clear the power-on or administrator passwords, complete the following steps:
Preparing to congure passwords 79
1. Shut down the operating system properly, then turn o the computer and any external devices, and
disconnect the power cord from the power outlet.
2. With the power cord disconnected, press the power button again to drain the system of any residual
power.
WARNING! To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to
disconnect the power cord from the wall outlet, and allow the internal system components to cool before touching.
CAUTION: When the computer is plugged in, the power supply always has voltage applied to the
system board even when the unit is turned o. Failure to disconnect the power cord can result in damage to the system.
Static electricity can damage the electronic components of the computer or optional equipment. Before beginning these procedures, ensure that you are discharged of static electricity by briey touching a grounded metal object. See the Safety & Regulatory Information guide for more information.
3. Remove the access panel.
4. Locate the header and jumper.
NOTE: The password jumper is green so that it can be easily identied.
5. Remove the jumper from pins 1 and 2.
6. Place the jumper on either pin 1 or 2, but not both, so that it does not get lost.
7. Replace the access panel and reconnect the external equipment.
8. Plug in the computer and turn on power. Allow the operating system to start. This clears the current
passwords and disables the password features.

80 Chapter 5 Conguring password security and resetting CMOS

Clearing and resetting the BIOS

The CMOS jumper resets BIOS settings to default, but does not clear the passwords or aect any of the other Security settings. On Intel systems with advanced manageability features, clearing CMOS will also partially unprovision AMT.
1. Turn o the computer and any external devices, and disconnect the power cord from the power outlet.
2. Disconnect the keyboard, monitor, and any other external equipment connected to the computer.
WARNING! To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to
disconnect the power cord from the wall outlet, and allow the internal system components to cool before touching.
CAUTION: When the computer is plugged in, the power supply always has voltage applied to the
system board even when the unit is turned o. Failure to disconnect the power cord can result in damage to the system.
Static electricity can damage the electronic components of the computer or optional equipment. Before beginning these procedures, ensure that you are discharged of static electricity by briey touching a grounded metal object. See the Safety & Regulatory Information guide for more information.
3. Remove the access panel.
CAUTION: Resetting CMOS will reset CMOS values to factory defaults. It is important to back up the
computer CMOS settings before resetting them in case they are needed later. Back up is easily done through Computer Setup. See Computer Setup (F10) Utilities on page 18 for information on backing up the CMOS settings.
4. Locate the CMOS jumper. For information on jumper location, see System board components on page 7.
NOTE: Make sure you have disconnected the AC power cord from the wall outlet. CMOS will not clear if
the power cord is connected.
5. Remove the jumper from pins 1 and 2.
6. Place the jumper on pins 2 and 3.
7. Wait for a few seconds.
8. Move the jumper back to pins 1 and 2.
9. Replace the access panel.
10. Reconnect the external devices.
11. Plug in the computer.
NOTE: When you plug power cord back in, the computer will power on by itself and perform two or
three reboots before returning to normal operation.
NOTE: You will receive POST error messages after clearing CMOS and rebooting advising you that
conguration changes have occurred. Use Computer Setup to reset any special system setups along with the date and time.
For instructions on Computer Setup, see Computer Setup (F10) Utilities on page 18.

A Linux technical notes

HP oers a variety of Linux solutions:
HP oers an Ubuntu preload on some Z Series Workstations.
HP certies and supports Ubuntu on some HP workstations.
HP certies and supports Red Hat Enterprise Linux (RHEL) on HP workstations.
HP certies SUSE Linux Enterprise Desktop (SLED) on HP workstations.
HP oers a SLED 11 preload on some older Z Series Workstations.
For Linux setup and restore procedures, see the user guide for your computer at http://www.hp.com/support/
workstation_manuals.
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 computer until the operating system
is successfully installed. Adding hardware might cause errors and prevent the operating system from installing correctly.

System RAM

HP supports dierent amounts of total RAM in various computers, based on the number of hardware DIMM slots and the capabilities of the system. The total memory supported for each conguration is listed in the Hardware Support Matrix for HP Linux Workstations at http://www.hp.com/support/linux_hardware_matrix.

Audio

All HP workstations come with built-in audio hardware. The audio hardware is supported by the Advanced Linux Sound Architecture (ALSA) drivers included with all modern Linux distributions.
The audio hardware provides basic playback and recording features. The ability to simultaneously play audio from multiple sources, such as applications and CDs, is provided in the ALSA driver that provides audio mixing. The performance of software audio mixing and playback is greatly improved in ALSA version 1.0.13 and later.
After the driver is installed, the optional NVIDIA and AMD graphics cards that are supported in HP workstations also provide audio functionality over HDMI. The signal can be passed through the DisplayPort connector to a monitor with audio capabilities. The vendor driver must be installed. Such a conguration might present two audio hardware choices. If you do not hear sound through the speakers, one possible 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 present a similar HDMI audio device that you can use through the DisplayPort interface. No proprietary driver is needed for this device, just a 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.
82 Appendix A Linux technical notes

Hyper-Threading Technology

The Z Series Workstations support Hyper-Threading Technology (HTT), an Intel technology that improves processor performance by enabling the processor to simultaneously perform multiple tasks. The operating system treats an HTT-enabled processor as two virtual processors and shares the workload between them when possible. This feature can be used only if the operating system support multiple processors and is specically optimized for HTT.
To enable HTT:
1. During startup, press F10 to enter Computer Setup (F10) Utility.
2. Select Advanced > System Options.
3. Set Intel Hyperthreading to Enable, and then press F10 to exit the menu.
4. Select Main > Save Changes and Exit.
5. Restart the system to enable HTT.
NOTE: On most recent Linux distributions (including RHEL 6, SLED 11, and updates to those streams), the
kernel automatically detects that HTT is enabled and works correctly.

NVIDIA Graphics Workstations

Some workstation congurations come with NVIDIA Quadro graphics hardware. HP recommends the use of NVIDIA drivers for best results on Linux systems.
HP provides recommended versions of the drivers with RPM-compatible installers for RHEL and SLED distributions. These are available from the HP Installer Kit for Linux and from workstation driver repositories on hp.com. When HP installers are used, their contents and documentation links are located in the /opt/hp/ nvidia folder.
When installing Linux on a workstation that contains an NVIDIA card, administrators should select a 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.
To customize display characteristics and resolutions when the computer is using an NVIDIA driver, execute the following command:
/usr/bin/nvidia-settings
To create and manipulate the /etc/X11/xorg.conf le, execute:
/usr/bin/nvidia-xconfig
