HE COMPUTER AT A GLANCE
Your Compaq Deskpro 4000S Personal Computer is a
networked PC in a dramatically smaller form factor. It is
designed specifically for convenient deployment in workspaceconstrained or countertop networked environments. An optional
mounting bracket allows you to mount the computer on, under,
or adjacent to your work surface in a horizontal or vertical
orientation to save more desk space. (See Chapter 5, “Upgrading
the Desktop Computer” for more information on mounting.)
Your computer combines an Intel Pentium Processor with MMX
technology (166 MHz or 200 MHz) with a generous 2.1-GB
hard drive and up to 32 MB of standard SDRAM system
memory.
Upgrades are simple with a slide-out system board and tool-less
removal of most internal components. This chapter describes the
features and components of your Compaq Deskpro 4000S
Personal Computer.

Routine Care
Follow these suggestions to take care of your computer and
monitor:
■
Operate the computer on a sturdy, level surface. Leave a
3-inch (7.6-cm) clearance at the back of the system unit and
above the monitor to permit the required airflow.
■
Never operate the computer with the cover removed.
■
Never restrict the airflow into the computer by blocking the
front vents or air intake. Do not place the keyboard, with the
keyboard feet down, directly against the front of the desktop
unit as this also restricts airflow.
■
Keep the computer away from excessive moisture, direct
sunlight, and extremes of heat and cold. For information
about the recommended temperature and humidity ranges
for your computer, refer to Appendix B, “Specifications."
■
Keep liquids away from the computer and keyboard.
■
Never cover the ventilation slots on the monitor with any
type of material.
Turn off the computer before you do either of the following:
✎
❏
Wipe the exterior of the computer with a soft, damp cloth
as needed. Using cleaning products may discolor or damage
the finish.

Manageability
Asset Management
Intelligent Manageability combines innovative hardware
technology with PC LAN management tools from Compaq and
other leading vendors to make Compaq computers easier to
inventory, troubleshoot, protect, and maintain. Intelligent
Manageability features focus on:
■
Asset Management
■
Fault Management
■
Security Management
■
Configuration Management
■
Integration Management
Conducting a physical inventory of personal computers, key
components, and monitors can be time-consuming and costly. The
Compaq Deskpro 4000S Asset Management solution to this
problem begins with AssetControl, hardware designed and built into
new Compaq personal computers, key components, and monitors
that support the VESA DDC2B, DIMM SPD, and EDID standards.
AssetControl features make it easy and cost-effective to
maintain an accurate, up-to-date inventory. AssetControl
features:
■
Provide detailed inventory information about various
components, including:

Reference Guide 2-3
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 Enhanced 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 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.
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. 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 all
Compaq Deskpro 4000S Personal Computers.
✎
Your Deskpro 4000S comes standard with non-ECC
DIMMs. To use this optional feature, you must replace
the standard DIMMs with ECC DIMMs. (Under normal
operations, your Compaq Deskpro 4000S Personal
Computer can use either standard DIMMs or ECC
DIMMs.)
Monitor Fault Diagnosis
New Compaq monitors detect when the operating temperature
exceeds the normal range or when a hardware fault occurs.
Monitor hardware faults may include the following:
Proactive Backup
■
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 software is an optional feature that initiates a
tape or PD-CD backup upon receiving notice of an impending
SMART hard drive failure.
Reference Guide 2-5
The Seagate Backup Exec SMART Client works with Seagate
Backup Exec tape backup software on the server, or with
Seagate Backup Exec software supporting a 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.
✎
Since your Compaq Deskpro 4000S Personal Computer
does not have an open bay for an internal PD-CD drive or
tape drive, Proactive Backup will require an external
drive.
Surge-Tolerant Power Supply
Thermal Sensor
2-6 Using Intelligent Manageability
An integrated, surge-tolerant power supply provides greater
reliability when the computer is hit with an unpredictable power
surge. This power supply is rated to withstand a 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
