Storage Options

SATA Emulation

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

There are three supported options: IDE, RAID, and AHCI (default).

IDE - This is the most backwards-compatible setting of the three options. Operating systems usually do not require additional driver support in IDE mode.

AHCI (default option) - Allows operating systems with AHCI device drivers loaded to take advantage of more advanced features of the SATA controller.

DPS Self-Test

Boot Order

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.

NOTE:

RAID is not available on USDT systems.

Allows you to execute self-tests on ATA hard drives capable of performing the Drive Protection

System (DPS) self-tests.

NOTE:

This selection will only appear when at least one drive capable of performing the DPS selftests is attached to the system.

Allows you to:

Specify the order in which EFI boot sources (such as a internal hard drive, USB hard drive,

USB optical drive, or internal optical drive) are checked for a bootable operating system image. Each device on the list may be individually excluded from or included for consideration as a bootable operating system source.

EFI boot sources always have precedence over legacy boot sources.

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

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

NOTE:

You can use F5 to disable individual boot items, as well as disable EFI boot and/or legacy boot.

NOTE:

MS-DOS drive lettering assignments may not apply after a non-MS-DOS operating system has started.

3 Serial ATA (SATA) Drive Guidelines and Features

NOTE:

HP only supports the use of SATA hard drives on these models of computer. No Parallel ATA

(PATA) drives are supported.

SATA Hard Drives

Serial ATA Hard Drive Characteristics

Number of pins/conductors in data cable 7/7

Number of pins in power cable 15

Maximum data cable length 39.37 in (100 cm)

Data interface voltage differential 400-700 mV

Drive voltages 3.3 V, 5 V, 12 V

Jumpers for configuring drive N/A

Data transfer rate 3.0Gb/s and 6.0Gb/s

SATA Hard Drive Cables

SATA Data Cable

Always use an HP approved SATA 3.0 Gb/s cable as it is fully backwards compatible with the SATA

1.5 Gb/s drives.

Current HP desktop products ship with SATA 3.0Gb/s and 6.0Gb/s hard drives.

SATA data cables are susceptible to damage if overflexed. Never crease a SATA data cable and never bend it tighter than a 30 mm (1.18 in) radius.

The SATA data cable is a thin, 7-pin cable designed to transmit data for only a single drive.

12

SMART ATA 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.

4 Identifying the Chassis, Routine Care, and Disassembly Preparation

This chapter provides general service information for the computer. Adherence to the procedures and precautions described in this chapter is essential for proper service.

CAUTION:

When the computer is plugged into an AC power source, voltage is always applied to the system board. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.

Chassis Designation

Small form factor chassis are available.

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.

Preventing Electrostatic Damage to Equipment

Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree 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.

15

Place items on a grounded surface before removing them from their container.

Always be properly grounded when touching a sensitive component or assembly.

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 feet with a maximum of one-megohm ± 10% resistance between the operator and ground.

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.

SDRAM) dual inline memory modules (DIMMs).

DIMMs

The memory sockets on the system board can be populated with up to two industry-standard DIMMs.

These memory sockets are populated with at least one preinstalled DIMM. You can populate the system board with up to either 4 GB per DIMM, for a total of 8GB maximum memory.

DDR3-SDRAM DIMMs

For proper system operation, the DDR3-SDRAM DIMMs must be:

● industry-standard 240-pin

● unbuffered non-ECC PC3-8500 DDR3-1066 MHz-compliant or PC3-10600 DDR3-1333

MHzcompliant

1.5 volt DDR3-SDRAM DIMMs

The DDR3-SDRAM DIMMs must also:

● support CAS latency 7 DDR3 1066 MHz (7-7-7 timing) and CAS latency 9 DDR3 1333 MHz

(9-9-9 timing)

● contain the mandatory JEDEC SPD information

In addition, the computer supports:

512-Mbit, 1-Gbit, and 2-Gbit 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:

Cable Management

The Small Form Factor chassis is a very compact computer and proper routing of the internal cables is critical to the operation of the computer. Follow good cable management practices when working inside the computer.

Keep cables away from major heat sources like the heat sink.

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. 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 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 up.

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.
