1.8.3 Processor Board

Prior to the 4150 model, there are two processor board PCAs with either 8-MB or 16-MB of

memory and with a level-2 cache populating the models with 100-, 120- and 133-MHz

processors. The MMX processor on the 4150 , 4150T, and 4160T are P55CLM processors

operating at 150 or 166 MHz. These processors are not compatible with 4131T, 4130T,

4120T, 4120, 4110, and 4100 models.

In each of the 4100 and 4200 systems there are two processor board PCAs with a level-

2 cache. The processor board contains the CPU, the OPTi 82C557 system Controller,

the OPTi 82C556 data buffer controller, and, if populated on the PCB, cache data

RAM. Also mounted on the processor board is an electronic temperature sensor that

interfaces to the system through the I²C bus.

The 4210T and 4220T processor boards include the 233- and 266-MHz MMX

processors and the MTXC controller, part of the Intel 430TX mobile chipset. The 4200

Family processor boards also include the electronic sensor that interfaces to the system

through the I²C bus.

1.8.4 Processor

The P54LM and the P55CLM Intel Pentium processors are fully compatible with the entire

installed base of applications for DOS, Windows, and OS/2, branch predition, and separate

code and data caches all provide increased performance over previous x86 processors.

Reduced voltage operation and enhanced SL power management features provide significant

power savings over other Pentium versions.

For the 4200 Family, the 233 MHz CPU core runs on a 1.8 V supply. The 266 MHz CPU core

runs on a 2.0 V supply. The interface for the 4200 Family is 2.5 V to 3.3 V.

For the 4100 Family, the CPU core runs on a 2.9V supply for lower power operation, while

the I/O buffers are powered at 3.3V for compatibility with the rest of the system.

1.8.5 System Memory

See Tables 1-1 and 1-2 for the system memory contained on models for the 4100 and

4200 Families. Up to 96-MB of expansion memory is available. Base memory is

onboard memory built into the system I/O board. Expansion memory consists of

memory expansion board kits available as user installable options.

1.8.6 Cache

The 4200 Family models have 256-KB or 512-KB of cache data RAM and 64-KB of

cache tag RAM if populated on the PCB are mounted on the processor module.

The 4110-4160T models have 256-KB of cache data RAM and 32-KB of cache tag

RAM if populated on the PCB are mounted on the processor module.

verifies that the system is configured and functioning properly

To run POST, complete the following steps:

1. Complete the preliminary steps. (Section 2.1).

2. Turn on the computer.

If POST does not detect any errors, the computer beeps once or twice to indicate that

POST has run successfully and boots from the hard drive or from a bootable diskette if

one is installed in the diskette drive.

2.4 POST Error Messages

This section contains typical error messages that may occur during the power-on self-

test (POST).

If you receive an error message read the description and follow the recommended

action or run Computer Checkup from the Diagnostics diskette. Information about

running Computer Checkup is presented later in this chapter.

If POST detects an error, one of the following events occurs:

■ A message with the prefix "WARNING" appears informing you where the error

occurred. The system pauses until you press F1 to continue.

■ A message with the prefix "FATAL" appears informing you where the error

occurred. After the message, the system emits a series of audible beeps. The system

then stops.

■ The system emits a series of audible beeps. The system then stops.

Warning messages indicate a potential problem exists such as a system configuration

error. When F1 is pressed, the system should resume. You should be able to correct

problems that produce WARNING messages.

IMPORTANT: When a WARNING message includes the prompt to "RUN SCU," run

Computer Setup. (Computer Setup replaces the SCU utility.)

Fatal errors emit a beep and may display a FATAL message. Fatal errors indicate

severe problems, such as a hardware failure. Fatal errors do not allow the system to

resume. Some of the fatal error beep codes are listed at the end of this section.

Solving Network Problems

This section provides guidelines for troubleshooting common Ethernet network

problems. Refer to these guidelines when you have determined that the computer in the

convenience base is not communicating with the network. These guidelines do not

discuss the process of debugging the network cabling.

These are common problems to check first. Refer to the tables on the following pages

for additional problems and solutions.

■ Ensure that the cabling is securely attached to the convenience base. A loose cable is

the most common cause of network problems. If the cable is loose, secure it and see

if the computer can communicate with the network.

■ Determine whether the current computer or another computer has communicated

with the network from the convenience base. If so, determine whether anything was

added or changed that could have stopped the network interface from working.

■ Run Diagnostics before installing the network drivers to verify that the network

interface is working correctly.

Chapter 4

Removal and Replacement

Preliminaries

This chapter provides general service information for the Compaq Armada 4100 and

4200 Families.

Adherence to the procedures and precautions described in this chapter is essential for

proper service.

4.1 Electrostatic Discharge

A sudden discharge of static electricity from a finger or other conductor can destroy

static-sensitive devices or microcircuitry. Often the spark is neither felt or heard, but

damage occurs. An electronic device exposed to electrostatic discharge (ESD) may not

be affected at all and will work perfectly throughout a normal cycle. Or it may function

normally for a while, then degrade 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.

electrostatic voltage levels.

4.1.2 Preventing Electrostatic Damage

to Equipment

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

determine the degree of sensitivity. The following proper packaging and grounding

precautions are necessary to prevent damage:

■ 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.

■ Always be properly grounded when touching a sensitive component or

assembly.

■ Place reusable electronic-sensitive parts from assemblies in protective

packaging or conductive foam.

Use transporters and conveyors made of antistatic belts and metal roller bushings.

Mechanized equipment used for moving materials must be wired to ground and proper

materials selected to avoid static charging. When grounding is not possible, use an

ionizer to dissipate electric charges.

4.1.3 Removing Batteries

Compaq recommends that you remove all batteries from the computer before beginning

the disassembly procedures. Failure to do so could cause damage to computer

components.

4.1.4 Preventing Damage to Drives

To prevent static damage to hard drives, use the following precautions:

■ Handle drives gently, using static-guarding techniques.

■ Store drives in the original shipping containers.

■ Avoid dropping drives from any height onto any surface.

■ Handle drives on surfaces that have at least one inch of shockproof foam.

■ Always place drives with the PCB assembly-side down on the foam.

4.1.5 Grounding Methods

The method for grounding must include a wrist strap or a foot strap at

a grounded workstation. When seated, wear a wrist strap connected to a grounded

system. When standing, use footstraps and a grounded floor mat.

4.1.6 Grounding Workstations

To prevent static damage at the workstation, use the following precautions:

■ Cover the workstation with approved static-dissipative material. Provide a

wrist strap connected to the work surface and properly grounded tools and

equipment.

■ Use static-dissipative mats, heel straps, or air ionizers to give added protection.

■ Handle electrostatic sensitive components, parts, and assemblies by the case or PCB

laminate. Handle them only at static-free workstations.

■ Avoid contact with pins, leads, or circuitry.

■ Turn off power and input signals before inserting and removing connectors or test

equipment.

■ Use fixtures made of static-safe materials when fixtures must directly contact

dissipative surfaces.

■ Keep work area free of non-conductive materials such as ordinary plastic assembly

aids and Styrofoam.

■ Use field service tools, such as cutters, screwdrivers and, vacuums, that are

conductive.

■ Use a portable field service kit with a static dissipative vinyl pouch that folds out of

a work mat. Also use a wrist strap and a ground cord for the work surface. Ground

the cord to the chassis of the equipment undergoing test or repair.

4.1.7 Grounding Equipment

Use the following equipment to prevent static electricity damage to the equipment:

Wrist Straps are flexible straps with a minimum of 1 megohm +/- 10% resistance to

the ground cords. To provide proper ground, a strap must be worn snug against the

skin. On grounded mats without banana-plug connectors, connect a wrist strap with

alligator clips.

Heel straps/Toe straps/Bootstraps can be used at standing workstations and are

compatible with most types of boots and shoes. On conductive floors or dissipative

floor mats, use straps on both feet with a minimum of 1 megohm resistance between

operator and ground. To be effective, the conductive strips must be worn in contact

with the skin.
