Fault Management

SMART II Hard Drive Fault Prediction

Fault Management features combine innovative hardware and
software technology to prevent the loss of critical data and
minimize unplanned downtime.

When a fault occurs, the computer displays a Local Alert
message containing a description of the fault and any
recommended actions. You can then view current system health
by using Compaq Insight Personal Edition. If the computer is
connected to a network managed by Compaq Insight Manager
or other SNMP-based management products (e.g., HP
OpenView or IBM Tivoli TME10 NetView), the computer also
sends a fault notice to the network management application.

The SMART II hard drive monitors hard drive activity to predict
failures before they occur. Fault prediction and failure indication
parameters, such as abnormal variations in spinup and seek
times, or non-correctable read and write errors, are tracked to
determine the hard drive condition. Should these errors become
significant, the computer displays a warning message. The
warning gives you time to back up the hard drive and replace it
prior to experiencing downtime or loss of data. The Prefailure
Warranty for SMART II hard drives allows you to replace these
drives, free of charge, before the drives fail.

2-4 Understanding and Using Intelligent Manageability

SMART II hard drives are compliant with the Small Form
Factor Committee Specification for Self-Monitoring, Analysis,
and Reporting Technology (SMART) Version II. SMART is the
industry standard technology, pioneered by Compaq and
originally called IntelliSafe, that allows you to prevent data loss
and minimize downtime, in concert with Compaq Insight
Management Agents.

Ultra ATA Integrity Monitoring

Ultra ATA Integrity Monitoring monitors the integrity of data as
it is transferred between an Ultra ATA hard drive and the
system’s core logic. If the computer detects an abnormal number
of transmission errors, the screen displays a Local Alert message
with recommended actions. An alert is also sent over the
network to the system administrator.

✎

To use this feature on Compaq Deskpro 6000 Series
personal computers, you must replace the standard Ultra
SCSI hard drive with an Ultra ATA hard drive. This
feature is standard on Compaq Deskpro 4000 Series
personal computers.

ECC Fault Prediction and Prefailure Warranty

When the computer encounters an excessive number of error
checking and correcting (ECC) memory errors, the screen
displays a Local Alert message. This message contains detailed
information about the errant memory module, allowing you to
take action before you experience non-correctable memory
errors. Run the Diagnostics Long RAM Test to validate ECC
memory errors. For more information about using Compaq
Diagnostics, refer to chapter 8, “Using Compaq Utilities.”

The Prefailure Warranty for ECC memory modules allows you
to replace these modules, free of charge, before the modules
actually fail. ECC memory modules are optional on most
Compaq Deskpro personal computers.

✎

To use this feature on Compaq Deskpro 4000 Series
personal computers, you must replace the standard
DIMMs with ECC DIMMs. This feature is standard on
Compaq Deskpro 6000 Series personal computers.

Reference Guide 2-5

Monitor Fault Diagnosis

Certain new Compaq monitors detect when the operating
temperature of the monitor exceeds the normal range or when a
hardware fault occurs. Hardware faults may include the
following:

■

Power voltage out of range

■

Power current out of range

■

Horizontal deflection

■

Vertical deflection

■

I/O controller operation failure

If the monitor detects one of these conditions, the computer will
send an alert over the network to the system administrator.

Proactive Backup

Proactive Backup software is an optional feature and initiates a
tape or PD-CD backup upon receiving notice of an impending
SMART hard drive failure.

The Seagate Backup Exec SMART Client works with Seagate
Backup Exec tape backup software on the server, or with
Seagate Backup Exec software supporting the PD-CD drive.
Together with the Insight Management Agents, this software
offers a Proactive Backup solution. For instructions on
configuring the Backup Exec SMART Client, contact your
systems administrator or refer to the Seagate Backup Exec
documentation.

Cheyenne Software, Inc. has also created an agent to support the
Proactive Backup solution. The SMART Drive Agent is the
component that recognizes and reacts to the SMART II hard
drive fault alerts. This agent is an extension to the Microsoft
Windows 95 tape backup agent for the standalone application,
ARCsolo for Windows. This agent works with the SMART II
hard drive to ensure that critical data will be protected in the
event of a hard drive failure.

Surge-Tolerant Power Supply

An integrated, surge-tolerant power supply provides greater
reliability when the computer is hit with an unpredictable power
surge. This power supply is rated and certified to withstand a

2-6 Understanding and Using Intelligent Manageability

Thermal Sensor

power surge of up to 2000 volts without incurring any system
downtime or data loss.

The thermal sensor is a hardware and software feature that
tracks the internal temperature of the computer. This feature
displays a warning message when the normal range is exceeded,
which gives you time to take action before internal components
are damaged or data is lost.

Security

Management

Your computer includes security features to protect the
computer and data from unauthorized access. You can view
Security Management features and current settings by using
Compaq Insight Personal Edition (locally), Compaq Insight
Manager (remotely), or PC LAN management applications from
the Desktop Management Solution Partners.

Using Remote ROM Flash

Remote ROM Flash allows the system administrator to safely
upgrade the ROM on remote Compaq Deskpro personal
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 Deskpro ROM images
over the network. It also results in greater productivity and
lower total cost of ownership.

Compaq created the Remote ROM Flash capability to be secure
and fail-safe. All Deskpro ROMPaq ROM images from Compaq
are digitally signed to ensure authenticity and minimize
potential corruptions. The ROM firmware includes a FailSafe
Boot Block that is protected during the flash process and allows
the Deskpro to be restarted, in the unlikely event of an
unsuccessful ROM flash.

Remote ROM Flash is performed in two stages:

1. System administrator uses the Remote Management Setup
software on a centralized management console to prepare a
Deskpro ROMPaq file.

2. System administrator uses a PC LAN management product,
such as Microsoft SMS, Intel LANDesk Manager, or
Symantec Norton Administrator for Networks, to distribute
and execute the file over the network to remote Deskpros.

✎

Use of Remote ROM Flash requires an established setup
password.

For more information on enabling Remote ROM Flash, refer to
the online Remote Management Administrators Guide. The

FailSafe Boot Block ROM

The FailSafe Boot Block ROM allows for system recovery in
the unlikely event of a ROM flash failure, for example, if a
power failure occurs during a ROM upgrade. The Boot Block is
a flash-protected section of the ROM that checks to validate the
system ROM each time power to the system is turned on.

■

If the system ROM is valid, the system starts normally.

■

If the system ROM fails the validation check, the FailSafe
Boot Block ROM provides enough support to start the
system from a ROMPaq diskette, which will program the
system ROM with a valid image.

Because there is no video or hard drive support from the Boot
Block ROM, the keyboard lights communicate information.
When the Boot Block detects an invalid system ROM, the
system sounds a series of beeps (one long and three short) and
flashes the three keyboard lights.

To recover the system after hearing the FailSafe Boot Block
beeps, complete the following steps:

1. Remove any diskettes from the diskette drive and turn off
the power.

2. Insert a ROMPaq diskette into the diskette drive.

3. Turn on power to the system.

If a setup password has been established, the Caps Lock

light will turn on.

4. Enter the setup password.

When the system successfully starts from the diskette and

reprograms the ROM, the three keyboard lights will turn

SING NETWORK COMMUNICATIONS

Your computer comes network ready, which means that it has
an embedded network controller and preinstalled network
device drivers. Access to a computer network immediately
increases your productivity potential. Once your network
connection is active, you can share resources such as a printer,
exchange information from computer to computer, and run
common software programs.

The Compaq Netelligent 10/100 TX Embedded UTP Controller
automatically senses the data throughput speed of the network,
10Base-T or 100Base-TX, and configures itself appropriately.

✎

100 Base-TX operation requires the use of Category 5
UTP cable with an RJ-45 network connection.

The controller also features Remote Wakeup, which allows the
system administrator to power on a client computer from a
remote location, through the use of supported PC LAN
management tools.

✎

Remote Wakeup support is available only when using an
RJ-45 network connection.

For more information on Remote Wakeup, refer to the
Power Management section of Chapter 2, “Understanding

Disabling the

Autosensing

Capabilities

Your computer automatically senses if the attached network
supports 10Mbs or 100Mbs and configures itself accordingly.
This process of determining the maximum network operating
speed is known as autosensing. The computer begins
autosensing whenever it loses a valid network link, for example,
if the cable is disconnected.

In addition to determining the network operating speed, the
computer determined if full-duplex is supported. Full-duplex
systems can transmit and receive information on the network
simultaneously. Half-duplex systems cannot transmit and
receive simultaneously. The different modes of operation are:

■

100Base-TX, full-duplex

■

100Base-TX, half-duplex

■

10Base-T, full-duplex

Installing Additional

Memory

You can expand computer memory by installing industry
standard, 168-pin synchronous DRAM dual inline memory
modules (DIMMs). For proper system operation, use 66MHz or
faster unbuffered DIMMs. DIMM upgrade kits are available as
options from Compaq.

The system board includes three memory module slots.
However, one or more of these memory module slots is used to
hold the standard 16- or 32-megabyte memory module(s). You
must replace the preinstalled memory module with a 128­megabyte memory module to achieve maximum memory of 384
megabytes.

Installing DIMM Modules

To install a memory module, complete the following steps:

1. If you have locked the Smart Cover Lock, use Computer
Setup to unlock the lock.
