Preliminary Notes

The following apply to all instructions included in this guide:

• When working on your system unit, and after removing the cover, place the unit

on a stable, static-free surface.

• When screws are used to secure components, partially tighten all of the screws

before completely tightening any one of them. This technique ensures proper alignment.

• Your system has been designed as a modular assembly. Do not force, bend or

apply excessive physical force when adding components.

• When performing system upgrades, protect all connectors and wiring from

breakage. Do not attempt to stretch the wiring over the metal edges of your

system’s frame.

1–2 3814 9779-000

Upgrading Your System

Avoiding Electrostatic Discharge

All electronic assemblies contain static-sensitive components, and your system can be

damaged by electrostatic discharge (ESD). The risk is greatest when the unit’s cover is off, and when components are being removed or added. To minimize this risk, take the following precautions.

Caution

Avoid producing friction static, which occurs most often when walking on new or newly cleaned rugs, or on any rug in a low humidity environment.

• While working on the system, wear an antistatic bracelet.

• Keep static-sensitive components (such as processor chips and video

memory chips) in their packages until you are ready to install them.

• Before removing a component from its package, sit down and hold

the package in one hand and touch the metal frame of your unit (a ground) with the other. Then, take the component out and install it immediately.

• Handle components by their edges. Avoid touching their leads,

connectors, or contact points.

• If you need to remove a component from the system, immediately

store it in antistatic packaging.

DRAM Memory

• All memory resides on the system board using industry standard 72-pin SIMM

technology.

• SIMMs are 60ns, with tin-lead connectors. You can use either EDO SIMMs or

Fast Page SIMMs with parity and ECC mode enabled.

• Two SIMM sockets are provided for base memory.

• The system board is upgradeable to 128MB DRAM on the motherboard.

• SIMMs must be identical in make, type and speed.

• The BIOS automatically recognizes the new amount of memory and it is not

necessary to run any set-up program. It recognizes the SIMM with or without parity. By default, the BIOS does not check for parity. However, the CMOS can be set to check for parity, if so desired.

3814 9779-000 1–11

Upgrading Your System

Upgrading DRAM Memory

You can upgrade the system memory by replacing the factory-installed SIMMs with higher-capacity SIMMs.

Caution

Since the SIMMs sockets on your motherboard are tin-plated, use only tinplated SIMMs when upgrading your system memory. If you use goldplated SIMMs, your system may become unstable.

To plan your SIMM configuration, refer to Table 1–1. Contact your Unisys Sales Representative for the availability of SIMMs.

Note: If a 36-bit SIMM is installed, use the “ECC/Parity Config” setting in the

BIOS to enable ECC/Parity support.

Preloaded Software

When you ordered your system, you specified which software programs would ship with your system and whether they would be preloaded onto the hard disk drive.

When you first turn on your system, it will attempt to launch the preloaded software you specified when you placed your order. If the system does not indicate that it has loaded the software, verify that you completed all hardware installation procedures correctly and that all connections are firmly in place. If that doesn’t solve the problem, reinstall the operating system software, following the procedures described in the documentation that came with your operating system. If the system still does not work, follow the troubleshooting instructions in Section 3.

3814 9779–000 2–3

Configuring Your System

Installing Additional Software

Installing Application Software

Application software includes commercial, off-the-shelf software packages that perform a variety of functions.

To load additional application software, follow the instructions that came with that software. These packages usually include an automated device driver installation program.

Installing Hardware Device Drivers

When you upgrade your hardware, you typically need to install hardware device drivers that will enable your operating system to recognized that hardware.

Device drivers usually come with the hardware. If not, you can often download the

most current versions of device drivers from each hardware manufacturer’s Web page.

Where to Go From Here

After running the BIOS Setup utility or installing addition applications or device drivers, restart your computer, and verify that the changes you made were successfully implemented. If you encountered any problems configuring your system, see Section

2–4 3814 9779–000

Section 3

Troubleshooting

What to Do When a BIOS Password is Forgotten

If a BIOS password is forgotten, authorized personnel may use the following procedure to clear the current password from the BIOS.

1. Turn off the system power.

2. Remove the system unit cover, as described in Section 1 in “Removing and

Replacing the System Unit Cover.”

3. Locate Jumper CPS1. For jumper locations, refer to the configuration label on the bottom of the motherboard.

4. Remove the jumper cap from pins 1-2.

5. Turn on the system.

6. After the BIOS is finished running, shut down the system.

7. Put the jumper cap back on pins 1-2 of jumper CPS1.

8. Replace the system unit cover, as described in Section 1 in “Removing and Replacing the System Unit Cover.”

9. Turn on the system.

You will now be able to open the BIOS setup utility and set a new password.

Typical Startup Sequence

When you turn on your system, it executes a predefined set of activities related to hardware initialization, confidence testing, and so forth. This set of activities is known as a startup sequence. Your system must complete each action in the sequence before you can consider it operational. Here is an overview of the startup sequence.

1. Your system receives power, and lights the Power LED on the front of the system unit. The power supply fan begins to rotate.

3–2 3814 9779–000

Troubleshooting

2. The system begins the Power On Self Test (POST). This test verifies that the system memory, system board, video controller, floppy disk drive, hard disk drive, drive controllers, and peripheral devices are all operational. The system emits one short beep to indicate that it has passed the POST.

Note: If the POST detects an error, it displays an error message on the monitor.

Also, it may emit a corresponding beep code, an error message consisting of speaker tones arranged in distinctive patterns. For information on what to do for POST errors, see “Solving Workstation Problems,” later

in this section.

3. As the POST executes, it displays system settings and values (such as processor type and speed, memory size, and so forth). Verify that these values match your actual system configuration.

a) If you need more time to read the screen, press the

PAUSE key.

b) To resume the test, press any key.

4. The keyboard LEDs blink on and off, and the Floppy Disk LED lights briefly.

5. The Hard Disk LED on the front of the system unit lights.

6. If you have a properly configured hard disk drive with a boot partition that contains operating system software, the operating system load messages appear on the monitor.

Note: If the operating system is not yet installed or the system configuration in

CMOS memory is not correct, the system does not issue load messages.

When a system experiences problems during startup, it either halts the sequence or generates an error message to indicate that a failure has occurred. The following paragraphs discuss some of the actions you can take to resolve an installation problem.

3814 9779–000 3–3

Troubleshooting

Solving Workstation Problems

Your system is designed for simple, trouble-free installation and maintenance. As a rule, your first attempt to power up your equipment will be successful. However, new systems sometimes have easily remedied problems.

As mentioned, your system follows a specific routine each time you turn it on. Variations from this routine indicate that your equipment may have a failure. If your system does not power up normally, do not be alarmed; fixing the problem can be as simple as reseating a loose cable.

When you think about a problem, keep in mind that your best tools are common sense and deductive reasoning. The following paragraphs guide you through basic installation troubleshooting.

Preliminary Checks

If your system does not power up correctly after you have installed it, you may have any of several minor problems. Problems that occur the first time you turn on your system are usually the result of installation errors or an incorrect CMOS hardware configuration. Occasionally, the problem is the result of an actual hardware failure.

If your system fails when you first start it, review the installation and configuration process and reread applicable sections of this guide or other pertinent documentation. Try to answer the following questions:

• Is there a floppy disk in drive A?

• Are all power cables connected correctly and all power switches turned on?

• Are all interface cable connections secure and correct?

• Are all jumper and switch settings on the system board and peripheral devices

correct? For information on the system board jumpers, see the configuration label on the bottom of the motherboard.

• Are all feature boards and drives installed correctly?

3–4 3814 9779–000

Troubleshooting

• Is the CPU securely connected to the motherboard?

• Are the values listed in the BIOS Setup utility correct? For more on the BIOS

Setup utility, see Section 2.

• If you have a problem booting your operating system, see the manuals that came with your software package for installation instructions.

If all these items are correct, or if you experience a problem that makes it impossible to answer these questions, read the following paragraphs on troubleshooting.

Troubleshooting an Installation Problem

If you have an installation failure that cannot be solved by the measures just discussed, you need to study the problem more closely. Your goal should be to systematically eliminate each possible cause of the problem until you have determined which component is causing the failure. You may find the following approach helpful.

1. If you have not already done so, turn off the system unit and the monitor.

2. If you have not already done so, disconnect any serial or parallel devices (printers, modems, and so forth) from the system unit.

3. Make sure the monitor and keyboard are correctly connected to the system unit.

4. Make sure that the system unit is connected to a properly grounded power outlet.

5. Turn on the monitor and make sure the brightness and contrast controls are turned up at least two-thirds of the way.

6. Turn on the system unit.

3814 9779–000 3–5

Troubleshooting

7. Observe the system’s startup sequence. Your system should complete each of the steps described in “Typical Startup Sequence,” earlier in this section. If the system does not complete a step, the component activated during that step may be faulty. For example, if the Floppy Disk LED does not light, you may have a bad floppy disk drive. For more on how to resolve problems of this sort, see “Common Problems,” later in this section. When you have fixed the problem, return to step 1.

8. If the system issues any error messages during the startup sequence, take the appropriate corrective action. For suggestions, see “Common Problems,” later in this section. When you have fixed the problem, return to step 1.

Note: If the system only issues a beep code, or the message does not tell you

enough to isolate the problem, contact your Unisys Customer Service Engineer.

9. If you isolate the problem to a specific device, repair or replace the device in question. When you have fixed the problem, return to step 1.

10. If you plan to store your operating system on a hard disk drive, partition and format the hard disk drive appropriately. For instructions, see the operating system manuals. Load the operating system from the drive.

11. Select each hard disk drive partition in turn to verify that all partitions can be accessed. If you cannot access the drive, the drive may be incorrectly partitioned or configured. For more information, see your operating system documentation and Section 2 of this guide.

12. If you were experiencing problems with a particular program, try running that program. If the problem recurs, see the software documentation for instructions on setting up program parameters. You can also try disabling cache memory and BIOS shadowing.

When your system passes all of the steps just described, you can consider the troubleshooting process complete. Be sure to turn off your system and reconnect any devices that you disconnected during your troubleshooting effort.

Troubleshooting

Common Problems

For ideas on how to solve problems that can occur during installation and operation, see Table 3–1. This table provides a list of common problems accompanied by several

solutions. Try each solution in the order presented in the table. Each time you implement one of these solutions, test it using the procedure described in “Troubleshooting an Installation Problem,” earlier in this section. If you still cannot correct the problem, contact your Unisys Customer Service Engineer for help.

Note: Faulty devices can cause problems that are difficult to isolate. An effective

approach is to replace each suspected device with a known good device, one at a time, and retest the system. If the problem disappears after you replace a device, you have isolated the problem. To find out which devices you can replace, see “Components You Can Replace,” later in this section. If the

problem persists, contact your Unisys Customer Service Engineer.
