■ Follow all cautions and instructions marked on the equipment.

■ Make sure that the voltage and frequency of your power source match the voltage

and frequency inscribed on the equipment’s electrical rating label.

■ Never push objects of any kind through openings in the equipment. Dangerous

voltages might be present. Conductive foreign objects could produce a short circuit that could cause fire, electric shock, or damage to your equipment.

Preface xxxiii

Caution – Hazardous voltages are present. To reduce the risk of electric shock and

danger to personal health, follow the instructions.

Caution – Do not operate Sun products without the access cover in place. Failure to

follow this precaution might result in personal injury or equipment damage.

Caution – There is a risk of personal injury and equipment damage. Follow the

instructions.

The book, Important Safety Information for Sun Hardware Systems, 816-7190, contains a listing of safety precautions for Sun workstations. The document is located in the packing carton for the Sun Blade 1500 workstation.

This chapter provides an overview of how to use this manual. The diagnostics and troubleshooting flowcharts within this manual can help you determine the root cause of problems that you might encounter with the Sun Blade 1500 workstation.

This chapter contains the following topics:

■ “Diagnostic Tools Available” on page 1-1

■ “About Flowcharts” on page 1-3

■ “How to Use This Manual” on page 1-4

1.1 Diagnostic Tools Available

The Sun Blade 1500 Service, Diagnostic, and Troubleshooting Manual uses displayed messages, system sounds, flowcharts, and firmware and software diagnostic tools to help you locate and identify workstation malfunctions.

The diagnostic tools used in the Sun Blade 1500 workstation include but are not limited to:

■ System displayed messages (such as flashing LEDs or error messages)

■ Workstation sounds (such as beeps)

■ Nonvolatile random access memory (NVRAM)

■ Power-on self-test (POST) diagnostics

■ OpenBoot PROM diagnostics

■ SunVTS validation test suite software

■ Solaris diagnostic commands

1-1

TABLE 1-1 provides a summary of these diagnostics tools.

TABLE 1-1 Summary of Diagnostic Tools

Diagnostic Tool Type of Tool What the Tool Does How Tool is Used

System LEDs Hardware Shows status of system or of

a specific component.

Power button LED indicates system state. TPE and optical drive LEDs indicate activity. Motherboard LED indicates standby power.

System sounds Hardware Indicates system condition. Beeps heard from workstation internal

speaker indicate POST completion, Solaris boot, or system failure. See

“Audio Responses” on page 3-12.

NVRAM Firmware Contains properties and flags

to configure system and diagnostic tests.

The setenv command typed at the ok prompt or the eeprom command in a terminal window can configure the OpenBoot PROM for diagnostics and automatic execution of scripts. See

“NVRAM” on page 6-1.

CHAPTER

Basic Troubleshooting

This chapter provides basic troubleshooting assistance. Topics include:

■ “Power-On Sequence” on page 3-1

■ “Display and Audio Responses” on page 3-2

■ “Troubleshooting Commands” on page 3-15

3.1 Power-On Sequence

When you power on the Sun Blade 1500 workstation, a series of tasks and processes brings the workstation to a user-ready state.

The following lists the sequence of power-on events that occur before a user can interact with the Sun Blade 1500 workstation.

1. Power button is pressed.

2. OpenBoot PROM initiates system power-on reset (SPOR).

3. OpenBoot PROM initiates power-on self-test (POST) (if enabled).

4. OpenBoot PROM loads device drivers.

5. OpenBoot PROM loads workstation configuration from NVRAM.

6. OpenBoot PROM initializes bus and PCI card self-test diagnostics.

7. OpenBoot PROM loads and executes boot block.

8. Boot block loads and executes bootstrap program.

9. Bootstrap loads Solaris kernel.

10. Bus connections and hardware components are probed.

3-1

11. init program is loaded and executed.

12. init program reads /etc/inittab.

13. init program launches rc scripts, which read, check, and mount file systems.

14. /etc/vfstab file system is checked and mounted.

15. Additional rc script files are executed.

If the power-on behavior seems erratic, see “Power-On Flowchart” on page 4-3

3.2 Display and Audio Responses

Component failures can often be diagnosed by looking at the monitor or listening to the system. Topics in this section include:

■ “Displayed Screens” on page 3-2

4.1 Power-On Flowchart

The “Power-On Flowchart” on page 4-3 indicates points where proper startup can be recognized. This flowchart helps identify what aspect of the Sun Blade 1500 workstation is at fault.

If you suspect a system failure, power on the system and follow the flowchart.

If you answer “No” to a question, direct your attention to the section provided or to other flowchart cross-references.

If you complete the flowchart without answering “No” to any questions yet you still suspect a failure with the Sun Blade 1500 workstation, see

Advanced Troubleshooting” on page 5-1 for more in-depth procedures.

4.2.1 Power Problem

There is a power problem.

Is the motherboard

LED0 on?

Attach known good electric device or tester to wall receptacle.

In normal operation, the motherboard LED0 glows as standby power is supplied to the workstation. You can view the glow from LED0 by looking into the system chassis through the rear system fan, or the mounting holes for the fan. If room lighting is bright, the glow might not be seen. Upon powering on the workstation, the system fans immediately spin to full speed. In a moment, they slow down to the required speed. Further into the boot process, the light in the Power button flashes, then stays lit. If there is a serious problem with the system memory, the workstation beeps three times and power off. Checking a component means checking the electrical connections and fit.

4.2.2 Hard Drive Problem

There is a problem with the hard drive.

Is a message about the

hard drive displayed?

Refer to the message tables. See “Displayed

Messages” on page 3-5.

Is the

operating system

running?

Does the hard

drive sound like that of a

known good system?

In normal operation, the hard drive spins up shortly after powering on the workstation. The drive might stop spinning later as part of the power management configuration. Clicking the mouse can bring the hard drive out of sleep state. Checking a component means checking the electrical connections and fit.

Refer to audio responses table. See “Audio

Responses” on page 3-12.

1. Save data.

2. Close all applications.

As superuser, run fsck:

# /usr/bin/fsck

Answer the questions.

Drive” on page 12-2.

Press the Stop-A keys.

4.2.3 System Fan Problem

There is a problem with the system fans.

In normal operation, the system fan’s speed is set according to the temperature inside of the workstation. If it is cold, the fans might not turn on at all and instead make a quiet grumbling sound. When fan bearings fail, they have a distinct noisy sound and the fan should be replaced. Do not mistake this for the full fan speed sound at power on. If might be difficult to hear the CPU fan spinning. Checking a component means checking the electrical connections and fit.

temperature greater than

15 °C (60 °F)?

Is the

rear fan exceptionally

4.2.4 USB Problem

There is a problem with a USB device (not keyboard or mouse), interacting with the system.

Is the

suspect device a Sun

supported device?

Disconnect all USB devices and attach the suspect device directly to the system.

This flowchart can only be used for Sun supported devices.

In normal operation, the USB ports allow for hot-plugging of peripherals. If the peripheral is not recognized, try plugging it in to another connector. Do not force the connection. If the peripheral is USB 2.0-compliant, and it is not attached to the USB 2.0 ports on the combination card, or to a USB 2.0 hub attached to the USB 2.0 ports, then it will have poor performance. The keyboard and mouse do not function in the USB 2.0 ports on the combination card. Checking a component means checking the electrical connections and fit.

Check the audio with OpenBoot Diagnostics. See “OpenBoot Diagnos-

tics” on page 8-5.

In normal operation, system sounds are played through the chassis speaker and headphone jack. Some audio drivers might prevent an audio application from making sound. Consult the system administrator in this situation. Loopback connectors can provide more thorough testing with OpenBoot Diagnostics or SunVTS. Checking a component means checking the electrical connections and fit.

Was an error

displayed?

Check motherboard and replace if necessary. See

“Motherboard Problem” on page 4-34.

Change the test-args parameter to loop- back. See “Configuring

OpenBoot Diagnostics” on page 8-7.
