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

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

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).

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

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.

Service Tools and Utilities
This section lists the tools and utilities available for acceptance testing, diagnosis, and
serviceability and provides recommendations for their use.
ROM-Based Diagnostics (RBDs)
Many ROM-based diagnostics and exercisers execute automatically at power-up and can
be invoked in console mode using console commands.
Recommended Use: ROM-based diagnostics are the primary means of testing the console
environment and diagnosing the CPU, memory, Ethernet, I/O buses, and SCSI and DSSI
subsystems. Use ROM-based diagnostics in the acceptance test procedures when you
install a system, add a memory module, or replace the following components: CPU
module, memory module, motherboard, I/O bus device, or storage device. Refer to
Chapter 3 for information on running ROM-based diagnostics.
Loopback Tests
Internal and external loopback tests are used to isolate a failure by testing segments of a
particular control or data path. The loopback tests are a subset of the ROM-based
diagnostics.
Recommended Use: Use loopback tests to isolate problems with the COM2 serial port, the
parallel port, and Ethernet controllers. Refer to Chapter 3 for instructions on performing
loopback tests.
Troubleshooting Strategy
DIGITAL Server 3300/3300R
1–11
Firmware Console Commands
Console commands are used to set and examine environment variables and device
parameters, as well as to invoke ROM-based diagnostics and exercisers. For example, the
show memory, show configuration, and show device commands are used to examine
the configuration; the set auto_action command is used to set an environment variable; and
the cdp command is used to configure DSSI parameters.
Recommended Use: Use console commands to set and examine environment variables and
device parameters and to run RBDs. Refer to Chapter 6 for information on configurationrelated firmware commands and Chapter 3 for information on running RBDs.
Operating System Exercisers (DEC VET)
The DIGITAL Verifier and Exerciser Tool (DEC VET) is supported by the Windows NT
operating system. DEC VET performs exerciser-oriented maintenance testing of both
hardware and operating systems.
Recommended Use: Use DEC VET as part of acceptance testing to ensure that the CPU,
memory, disk, tape, file system, and network are interacting properly. Also use DEC VET
to stress test the user's environment and configuration by simulating system operation
under heavy loads to diagnose intermittent system failures.

Several information resources are available, which are described briefly in the following
sections.
Alpha Firmware Updates
Under certain circumstances, such as a CPU upgrade or replacement of the system
motherboard, you may need to update your system firmware. An Alpha Firmware CDROM is available with the Windows NT operating system. Operating system and
firmware revisions must be compatible. The latest version of the firmware files can also be
downloaded from the Internet as follows:
http://www.windowsnt.digital.com
Fail-Safe Floppy Loader
The fail-safe floppy loader diskette (AK-R4VLA-CA) can be ordered. Call 1-800-
DIGITAL
, or download the firmware from the Internet (using the firmware update address
above) to create your own fail-safe loader diskette.
ECU Revisions
The EISA Configuration Utility (ECU) is used for configuring EISA options on
DIGITAL
Server systems. Systems are shipped with an ECU kit, which includes the ECU license.
Customers who already have the ECU and license, but need the latest ECU revision (a
minimum revision of 1.10 for
DIGITAL

Power-Up Diagnostics and Display
This chapter provides information on how to interpret error beep codes and the power-up
display on the console screen. In addition, a description of the power-up and firmware
power-up diagnostics is provided as a resource to aid in troubleshooting. The following
topics are covered:
• Interpreting error beep codes at power-up
• Interpreting the power-up screen display
• Troubleshooting mass-storage problems indicated at power-up or storage devices
missing from the show config display
• Location of storage device LEDs
• Control panel LEDs
• Troubleshooting PCI bus problems indicated at power-up or PCI devices missing from
the show config display
• Troubleshooting EISA bus problems indicated at power-up or EISA devices missing
from the show config display
• Use of the fail-safe loader
• The power-up sequence
• Firmware power-up diagnostics

Interpreting Error Beep Codes
If errors are detected at power-up, audible beep codes are emitted from the system. For
example, if the SROM code could not find any good memory, you would hear a 1-3-3
beep code (one beep, a pause, a burst of three beeps, a pause, and another burst of three
beeps).
Be sure to check that the CPU daughter board is properly seated in its connector if errors
are reported.
NOTE: A single beep is emitted when the SROM code completes successfully. The
console firmware then continues with its power-up tests.
The beep codes are the primary diagnostic tool for troubleshooting problems when console
mode cannot be accessed. Refer to Table 2-1 for information on interpreting error beep
codes.
