Troubleshooting Strategy
This chapter describes the troubleshooting strategy for DIGITAL Server 3300/3300R
systems.
• Questions to consider before you begin troubleshooting
• Diagnostics flows for each problem category
• List of service tools and utilities
• List of information services
Questions to Consider
Before troubleshooting any system problem, first check the site maintenance log for the
system's service history. Be sure to ask the system manager the following questions:
• Has the system been used and did it work correctly?
• Have changes to hardware or updates to firmware or software been made to the system
recently? If so, are the revision numbers compatible for the system? (Refer to the
hardware and operating system release notes).
• What is the state of the system? Is the operating system running?
• If the operating system is down and you are not able to bring it up, use the diagnostic
beep codes and console environment diagnostic tools, such as the power-up display on
the VGA terminal and ROM-based diagnostics (RBDs).
If the operating system is running, use the operating system environment diagnostic tools,
such as the DEC VET exerciser.

Troubleshooting Strategy
1–2 DIGITAL Server 3300/3300R
Problem Categories
System problems can be classified into the following five categories. Using these
categories, you can quickly determine a starting point for diagnosis and eliminate the
unlikely sources of the problem.
• Power problems (Table 1-1)
• No access to console mode (Table 1-2)
• Console-reported failures (Table 1-3)
• Boot failures (Table 1-4)
• Operating system-reported failures (Table 1-5)

Troubleshooting Strategy
DIGITAL Server 3300/3300R 1–3
Table 1-1 Power Problems
Symptom Action
System does not power on. Check the power source and power cord.
Check the On/Off setting on the operator control
panel. Toggle the On/Off button to off, then back to
the On position to clear a remote power disable.
Check the indicator lights on the operator control
panel. If the green Power OK light is off and amber
Halt/Remote Power Off light is on, the system may
be powered off by one of the following:
• A remote management console command
• System software
• Fan failure
• Overtemperature condition
• Power supply failure
• Power select switch on power supply is set to
120V for a 220V power source
Check that the ambient room temperature is within
environmental specifications
(10–40°C, 50–104°F).
Check that internal power supply cables are plugged
in at the system motherboard.
Power supply shuts down after a
few seconds (fan failure). Listen to hear if the fan is spinning at power-up. A failure of the fan causes the system to shut down after
a few seconds.
Enter the remote management console and query
system status/alerts (using the status command) for
an indication of fan failure or overtemperature
condition. Refer to Chapter 4 for instructions.

Troubleshooting Strategy
1–4 DIGITAL Server 3300/3300R
Table 1-2 Problems Getting to Console Mode
Symptom Action
Power-up screen is not
displayed. Interpret the error beep codes at power-up (Chapter 2) for a failure detected during self-tests.
Check that the keyboard and monitor are properly
connected and turned on.
If the power-up screen is not displayed, yet the system
enters console mode when you press the Return key, check
that the console environment variable is set correctly.
If you are using a VGA monitor as the console terminal,
the console variable should be set to graphics. If you are
using a serial console terminal, the console environment
variable should be set to serial.
If you are using the standard onboard VGA controller, the
VGA enable (J27) jumper on the motherboard must be
enabled. Refer to Appendix A.
If a VGA controller other than the standard on-board VGA
controller is being used, refer to “Console Port
Configurations” in Chapter 6 for more information.
If console is set to serial, the power-up screen is routed to
the COM1 serial communication port and cannot be viewed
from the VGA monitor (see “Console Port Configurations”
in Chapter 6). Continued on next page

Troubleshooting Strategy
DIGITAL Server 3300/3300R 1–5
Table 1-2 Problems Getting to Console Mode (continued)
Symptom Action
Try connecting a console terminal to the COM1 serial
communication port (“Console Port Configurations” in
Chapter 6). Check the baud rate setting for the console
terminal and the system. The system baud rate setting is
9600. When using the COM1 port, you must set the
console environment variable to serial.
If none of the above considerations solve the problem,
check that the J1 jumper on the CPU daughter board is not
missing. Refer to Chapter 8 for the standard boot setting.
If the system has a customized NVRAM file, try powering
up or resetting the system with the Halt button set to the
“In” position. The NVRAM script will not be executed
when powering up or resetting the system with the Halt
button depressed.
For certain situations, power up using the fail-safe loader
(Chapter 2) to load new console firmware from a diskette.

Troubleshooting Strategy
1–6 DIGITAL Server 3300/3300R
Table 1-3 Problems Reported by the Console
Symptom Action
Power-up tests do not complete. Interpret the error beep codes at power-up, and
check the power-up screen for a failure detected
during self-tests (see Chapter 2).
The system attempts to boot from
the floppy drive after a checksum
error is reported (error beep code
1-1-2 or 1-1-4).
Reinstall firmware by inserting a fail-safe loader
diskette. Refer to the procedure provided with the
firmware update documentation.
Console program reports error: Use the error beep codes and/or console terminal to
determine the error (see Chapter 2).
• Error beep codes report an
error at power-up.
• Power-up screen includes
error messages.
Examine the console event log (enter the more el
command) or the power-up screen to check for
errors detected during power-up (see Chapter 2).
• Power-up screen or console
event log indicates problems
with mass storage devices.
• Storage devices are missing
from the show config display.
Use the “Mass Storage Problems” troubleshooting
tables in Chapter 2 to determine the problem.
Use the “Mass Storage Problems” troubleshooting
tables in Chapter 2 to determine the problem.
