Description of Modes

Microsoft Windows MultiPoint Server 2011 can operate in two different modes described below:

Maintenance, see

●

Normal, see

●

Maintenance

Maintenance mode is the state of the MultiPoint Server 2011 system in which the administrative user
performs maintenance tasks. No stations switch to this mode—this mode ends all user sessions. All
software and driver installations are performed in Maintenance mode, including updating system
settings.

Maintenance Mode can be accessed by choosing "Switch to Maintenance Mode" from within the
MultiPoint Manager.

Normal

Normal mode is the default mode. Users normally log in and perform individual task on each station in
Normal mode. Each session runs a separate RDP session. Software updates and driver installations
should not be performed in Normal mode.

Maintenance on page 8

Normal on page 8

Performance Considerations

Remapping Stations

MultiSeat uses an auto-mapping function to associate each attached zero client. If the auto-mapping
function fails to work, then the user can manually associate their workstation with this function. Auto­mapping does not apply to the host PC station. The remap function could be used to reconfigure the
host PC station’s association if the configuration has changed.

To perform this action, choose "Remap all stations" from the MultiPoint Manager.

◦

◦

◦

NOTE: The maximum cable length supported by USB 2.0 specification is five meters.

You cannot mix t100 or t150 clients with t200 Zero Clients connected to the same MultiSeat host
PC, but you can mix t100 and t150 client devices.

HP MultiSeat Thin Client t100 Series (t100 and t150 client devices)

●

Windows MultiPoint Server 2011 supports PS/2 keyboard/mouse on the host system.

Windows MultiPoint Server 2011 supports audio and microphone on the host PC station.

NOTE: For this to function, the host stations must be configured using PS/2 keyboard and

mouse. It will not function with USB keyboard or mouse.

Windows MultiPoint Server 2011 supports daisy-chaining of client devices connected by
USB cable. Daisy-chaining can simplify cabling and extend the distance between the host
and a station without additional USB hubs.

NOTE: Daisy-chaining is not supported for Ethernet-connected zero clients.

HP supports no more than three client devices per chain.

All clients in the chain must be AC powered.

◦ All t100 series client devices are connected by USB cable directly to the host system.

The MultiSeat Thin Client t100 has ports for PS/2 keyboard/mouse, microphone, speakers/

◦

headphones, and a VGA monitor.

◦ The MultiSeat Thin Client t150 has two USB ports and a power connector, which can be

used with an AC adapter or with an HP monitor with power-pass-through (such as the HP
LE1851wt 18–inch Widescreen LCD Monitor). (AC adapter and monitor are sold
separately).

If the optional DC adapter is not connected, the t150 client supports only one 100 mA USB

◦

device (low power), such as some flash drives.

● HP t200 Zero Client for MultiSeat

NOTE: The host PC must be an HP MultiSeat ms6200 Desktop. The t200 Zero Client is not

supported with the HP MultiSeat ms6000 Desktop.

The t200 Zero Clients may be connected by Ethernet or by USB cable directly to the host

◦

system.

The t200 Zero Client has ports for Ethernet, microphone, speakers/headphones, and a

◦

VGA monitor.

The t200 Zero Client has four USB ports and a power connector, which can be used with

◦

an AC adapter or with an HP monitor with power-pass-through (such as the HP LE1851wt

10 Chapter 2 HP MultiSeat Computing Solution – Best Practices

Best Practices for Setting Up a MultiSeat Environment

A USB-connected environment is ideal when plug-and-play simplicity is desired or in settings with no
Ethernet network infrastructure. An Ethernet-connected environment is ideal when the distance
needed between the host PC and its clients must be greater than USB allows. It can also help reduce
cable clutter around the host PC.

NOTE: If the t200 Zero Client drivers are not preinstalled on your host PC, please download them

from the HP website. Go to hp.com, click SUPPORT & DRIVERS, click Drivers & Software, type the
host PC model number (ms6200) in the field, and click SEARCH to find the latest t200 Zero Client
drivers.

USB-connected MultiSeat Environment

This setup is suitable for either t100 series clients or t200 Zero Clients.

NOTE: You cannot mix t100 series clients and t200 Zero Clients connected to the same MultiSeat

host PC, but you can mix t100 and t150 client devices.

▲ Connect the zero clients to the host PC:

Connect singleton zero clients (not in a daisy chain) via USB cable directly to the host PC.

●

To connect zero clients in a daisy chain, connect each client via USB cable to the next, and

●

then connect one end of the daisy chain via USB cable to the host PC.

NOTE: Up to three zero clients may be connected by USB cable in a daisy chain.

Each zero client in a daisy chain must be powered using the optional power adapter
connected to an AC power source or an HP monitor with power-pass-through.

Ethernet-connected MultiSeat Environment

This setup is suitable for the t200 Zero Client only.

● Daisy chaining off an Ethernet-connected zero client is not supported.

With no USB connection to supply power, zero clients must have another source of power: either

●

an optional power adapter connected to an AC power source or an HP monitor with power-pass­through.

An Ethernet network infrastructure is required.

●

This should be a 100 Mb or one Gb system.

◦

◦ DHCP is highly recommended.

Can only see t200 Zero Clients on same subnet as host PC.

◦

Best Practices for Setting Up a MultiSeat Environment 11

Ethernet-connected t200 Zero Clients look like local USB devices to the operating system as

●

displayed in MultiPoint Manager.

There are two types of hardware reset:

●

Clear assignment—hold recessed reset button while powering on until LED blinks blue/

◦

amber

Clear all (factory defaults)—hold the reset button for seven seconds until the LED goes out.

◦

This does not need to be during power on, but the device must NOT be connected to a host
(according to the Network Stations tab in MultiPoint Manager).

1. Connect the host PC to the LAN via Ethernet cable.

2. Connect the t200 Zero Clients to the LAN via Ethernet cable.

3. (Recommended) Power on one at a time or small groups at a time.

4. (Recommended) In the Network Stations tab of the MultiPoint Manager, change the Name and/

or Location.

5. (Recommended) Label each unit.

6. Use one of two methods of assigning t200 Zero Clients to a host PC:

Client-based (hotkey)

●

Host-based (GUI)

●

Client-based (hotkey) Assignment

1. In the Network Stations tab of the MultiPoint Manager, set up hotkeys on hosts.

Each host in the subnet must have a unique hotkey.

2. Ensure that the t200 Zero Client is not already assigned to a host by confirming that the LED

blinks alternately blue and amber. Refer to the reset methods above, if needed.

3. On the keyboard connected to the t200 Zero Client, press the key that matches the hotkey set

on the host PC to which you want this client assigned.

4. Wait 30 seconds to one minute until device is ready for login.

Host-based (GUI) Assignment

1. Go to the Network Stations tab in MultiPoint Manager.

2. Select the client(s) you want to assign to this host.

3. Choose Assign to this server from the task area on the right.

NOTE: You may include USB-connected t200 Zero Clients and daisy-chained t200 Zero Clients

along with Ethernet-connected t200 Zero Clients on a host PC. They must be connected as described

USB-connected MultiSeat Environment on page 11.

Best Practices for Installation of Drivers with the Volume License Operating System

Recommended Method (Automatic Driver Installation)

Before installing the Windows MultiPoint Server 2011 Volume License operating system from DVD,
go to www.hp.com and search for drivers for your host PC model. Choose the MultiPoint 2011 OS
then locate and download the "HP Install Assistant" Softpaq. (Using this method, you will not need to
download any other driver Softpaqs.) Extract the Softpaq contents and carefully follow the included
PDF instructions. This will create a USB flash drive that when inserted during the DVD install of the
OS, will automatically install all of the necessary drivers.

Manual Driver Installation

If manual installation of the drivers is required, heed the following advice:

● Perform all driver and software installations in Maintenance mode.

● Do not connect the client to the host system until all drivers are installed.

Install the graphics driver BEFORE installing the other drivers; otherwise, the solution may not

●

operate correctly.

● Install all system drivers (drivers for each HP host PC models are available on the HP.com

website). You do not need to download the "HP Install Assistant" Softpaq when installing drivers
manually.

Switch back into Maintenance mode as necessary until all drivers are installed.

●

●

Use the 32-bit version of Internet Explorer
Player).

Ensure that the latest Microsoft updates are installed.

●

Verify that the BIOS on the HP MultiSeat host PC is the latest version to be found on HP.com.

●

Follow the Quick Setup Poster sequence to connect the clients after the drivers are loaded.

●

Re-launch into Normal mode when all drivers and software are installed.

Best Practices for Installation of Drivers with the Volume License Operating System 13

Performance Considerations

Consider the following when evaluating performance on a MultiSeat solution:

Each client session, including the host system, will offer native resolution of the monitor attached

●

to the client/host. The MultiPoint operating system does not attempt to reduce the resolution or
color depth of each session.

Performance will be a factor of the application running in each session and the number of client

●

sessions running per host system.

Some Flash-enabled websites can be highly CPU-intensive, even for a single-desktop system.

●

Understandably, running several MultiSeat terminals with Flash will cause the CPU to run very
high. This in turn can cause performance degradation at the clients including, but not limited to,
slow mouse and keyboard response. If this happens, reduce the number of clients until you get
an acceptable response.

The best and simplest path to gain better performance is to ensure the best fit of the MultiSeat

●

host system, Essential or Extended configurations, with the main use of the MultiSeat solution.

MultiPoint operating system user sessions have the Internet Explorer 8 browser installed. It is

●

strongly recommend that compatibility mode is used to mitigate any compatibility issues with
older websites.

Next, you must ensure the best fit for the number of clients attached to each host system. The

●

best reference for this is the Microsoft TechNet. See

External Links on page 14.

Troubleshooting

Windows MultiPoint is unable to display the monitor's native or recommended resolutions for some larger
monitors.

Cause Solution

The MultiSeat zero client has a lower maximum resolution
than some larger monitors can display.

14 Chapter 2 HP MultiSeat Computing Solution – Best Practices

The maximum resolution supported by the t200 Zero Client is
2048 x 1152.

Switching from USB to PS/2 mouse or keyboard (and vice versa) requires the stations to be remapped.

Cause Solution

The MultiPoint operating system stores the previous
mapping of keyboards and mice to each display, and it
attempts to continue to use that mapping.

The host USB mouse has failed on some USB ports after re-associating .

Cause Solution

Not all pairs of USB ports on the host PC can be used for a
USB keyboard and mouse.

WMSReserved and SRCShell user accounts are found.

Cause Solution

These user accounts exist on purpose. These user accounts are a critical part of the Windows

Auto-Logon did not work properly.

Cause Solution

Use the Remap all stations feature in the MultiPoint
Manager when changing keyboard or mouse configurations
in any way.

HP highly recommends using a PS/2 keyboard and a PS/2
mouse on the host PC.

MultiPoint 2011 operating system and should not be deleted
or tampered with.

The MP2011 Auto-Login feature cannot work if the user
account used does not have a password.

Storage Options eSATA Port (some models)

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

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

SATA Emulation

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

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

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

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

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

NOTE: RAID is not available on USDT systems.

4 Routine Care, SATA Drive Guidelines,

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.

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.

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.

●

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

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.

Electrostatic Discharge Information 31

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.

Routine Care

General Cleaning Safety Precautions

To clean the computer case, follow the procedures described below:

To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.

●

For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping it with

●

a cloth or swab dampened with clear water.

For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed as the alcohol will

●

evaporate quickly and not leave a residue.

After cleaning, always wipe the unit with a clean, lint-free cloth.

●

Occasionally clean the air vents on the computer. Lint and other foreign matter can block the

●

vents and limit the airflow.

Cleaning the Keyboard

Follow all safety precautions in General Cleaning Safety Precautions on page 32 before cleaning the
keyboard.

To clean the tops of the keys or the keyboard body, follow the procedures described in

Computer Case on page 32.

When cleaning debris from under the keys, review all rules in

on page 32 before following these procedures:

CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from

under the keys.

Visible debris underneath or between the keys may be removed by vacuuming or shaking.

●

Canned, pressurized air may be used to clean debris from under the keys. Caution should be

●

used as too much air pressure can dislodge lubricants applied under the wide keys.

If you remove a key, use a specially designed key puller to prevent damage to the keys. This

●

tool is available through many electronic supply outlets.

CAUTION: Never remove a wide leveled key (like the space bar) from the keyboard. If these

keys are improperly removed or installed, the keyboard may not function properly.

Cleaning under a key may be done with a swab moistened with isopropyl alcohol and squeezed

●

out. Be careful not to wipe away lubricants necessary for proper key functions. Use tweezers to
remove any fibers or dirt in confined areas. Allow the parts to air dry before reassembly.

Cleaning the Monitor

drives only.

CAUTION: As each subassembly is removed from the computer, it should be placed away from the

work area to prevent damage.

34 Chapter 4 Routine Care, SATA Drive Guidelines, and Disassembly Preparation

Cables and Connectors

Most cables used throughout the unit are flat, flexible cables. These cables must be handled with
care to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or
removal from the connector. Handle cables by the connector whenever possible. In all cases, avoid
bending or twisting the cables, and ensure that the cables are routed in such a way that they cannot
be caught or snagged by parts being removed or replaced.

CAUTION: When servicing this computer, ensure that cables are placed in their proper location

during the reassembly process. Improper cable placement can damage the computer.

Hard Drives

Handle hard drives as delicate, precision components, avoiding all physical shock and vibration. This
applies to failed drives as well as replacement spares.

● If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective

packaging and label the package “Fragile: Handle With Care.”

Do not remove hard drives from the shipping package for storage. Keep hard drives in their

●

protective packaging until they are actually mounted in the CPU.

Avoid dropping drives from any height onto any surface.

●

If you are inserting or removing a hard drive, turn off the computer. Do not remove a hard drive

●

while the computer is on or in standby mode.

Before handling a drive, ensure that you are discharged of static electricity. While handling a

●

drive, avoid touching the connector. For more information about preventing electrostatic
damage, refer to

Do not use excessive force when inserting a drive.

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 3.0 Gb/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.

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.

Cable Management

Always 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 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.

36 Chapter 4 Routine Care, SATA Drive Guidelines, and Disassembly Preparation

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.

Front Bezel on page 40)..

4. Replace the front bezel.

Memory

The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3­SDRAM) 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 16-GB of memory configured in a
high-performing dual channel mode.

DDR3-SDRAM DIMMs

CAUTION: This product DOES NOT support DDR3 Ultra Low Voltage (DDR3U) memory. The

processor is not compatible with DDR3U memory and if you plug DDR3U memory into the system
board, it can cause the physical damage to the DIMM or invoke system malfunction.

Bezel Blanks 41

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 MHz-

●

compliant

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: The system will not operate properly if you install unsupported DIMMs.

Populating DIMM Sockets

There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory
channel B. Sockets DIMM3 and DIMM4 operate in memory channel A.

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 1-GB DIMMs and Channel B is populated with one 2-GB 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 2-GB DIMM, and three 1-GB
DIMMs, Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel
B should be populated with the other two 1-GB DIMMs. With this configuration, 4-GB will run as
dual channel and 1-GB will run as single channel.

In any mode, the maximum operational speed is determined by the slowest DIMM in the system.

●

42 Chapter 5 Removal and Replacement Procedures

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.

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

B 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 mm

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.

C 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,

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, reconfigure the computer to the Full Boot Every x Days mode, using Computer Setup.

NOTE: For more information on Computer Setup, see Computer Setup (F10) Utility on page 16.

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.
