Preface

Troubleshooting is the process of isolating and diagnosing problems. When

your system does not operate as described in your Operation manual, use the

information in this manual to isolate and diagnose the problem.

This manual contains three chapters and two appendixes:

• Chapter 1 lists problems you may experience at power-up and provides

corrective actions.

• Chapter 2 lists problems you may experience during normal operation and

provides corrective actions.

• Chapter 3 tells you how to run the MicroVAX Diagnostic Monitor (MDM),

a diagnostic tool you can use to test your system periodically or to isolate a

particular problem.

• Appendix A contains illustrations showing the location of your system controls

and indicators.

• Appendix B describes how to write-protect your EF/RF-Series ISE.

If the corrective actions suggested in Chapters 1 and 2 do not solve the problem,

call your Digital Services representative.

The following conventions are used in this manual.

Convention Meaning

Key A terminal key used in text and examples. For example, Break

indicates that you press the Break key on your terminal keyboard.

Ctrl/C Hold down the Ctrl key while you press the C key.

NOTE Provides general information about the current topic.

CAUTION Provides information to prevent damage to equipment or software.

Troubleshooting During Power-Up

After you turn on your system, the processor performs a series of self-tests

and startup routines. After successful completion of the self-tests, if the Break

Enable/Disable switch is set to disable (down), your system autoboots system

software.

1.1 Autobooting the System Software

Your system boots automatically (autoboots) from a speciﬁed drive if you have

speciﬁed a boot device by way of the command SET BOOT device-name from

console mode. Your system continues to boot from the speciﬁed drive each time

it is turned on, until you specify a different device by entering the SET BOOT

device-name command again.

Your system stores the following console parameters in nonvolatile memory.

Parameter Values Comment

Language 1 - 15 Sets the language and the

keyboard type used under the

console

ControlP 0,1 (disabled,enabled) Sets ControlP as a halt condition

instead of a break, if the break

enable switch is set for enable.

Halt 0 - 4 (or DEFAULT,

RESTART, REBOOT,

HALT, RESTART_

REBOOT)

Deﬁnes the action on halt

DSSI_ID Bus 0/A 0 - 7 The DSSI node ID for the CPU

DSSI adapter 0

DSSI_ID Bus 1/B 0 - 7 The DSSI node ID for the CPU

DSSI adapter 1

Troubleshooting During Power-Up 1–1

Parameter Values Comment

DSSI_ID Bus 2/C 0 - 7 The DSSI node ID for the CPU

DSSI adapter 2

DSSI_ID Bus 3/D 0 - 7 The DSSI node ID for the CPU

DSSI adapter 3

BFLG Hex number up to 8

digits Sets the default R5 boot ﬂag

BOOT Boot device Sets the default boot device

If ac power is lost, this information is retained. When ac power is restored,

type SHOW SAVED_STATE at the >>> prompt. Your system displays these

parameters with the values they had at the time of the ac power loss. You can

then change any of these values. To boot your system, type Bat the >>> prompt.

If you do not enter the SET BOOT device-name command, your system boots

from the Ethernet port, EZA0.

1.2 Troubleshooting Power-Up Problems

Refer to the descriptions of problems and corrective actions in the following

sections. If the action(s) listed do not solve the problem, call your Digital service

representative.

1.2.1 Problems During Self-Tests

Problem Possible Cause Corrective Action

No response when

Power switch turned

on; AC

Present indicator not lit.

System not plugged in. Set Power switch to 0. Plug in

system. Set Power switch to 1.

No power at wall outlet. Use different wall outlet or check

circuit breaker controlling power to

wall outlet.

Power switch (circuit

breaker) tripped (in

position 0).

Wait 1 minute, then set Power

switch to position 1. If it trips

again, call your Digital Services

representative.

Power cable incorrectly

installed. Set Power switch to 0. Check that

cable is fully seated in socket. Set

Power switch to 1.

1–2 Troubleshooting During Power-Up

Problem Possible Cause Corrective Action

AC Present indicator lit;

DC OK indicator not lit. Power Control Bus cable

connected to Secondary

In (SI) connector on

power supply.

Turn on system or expander

connected to Power Bus Out (MO)

connector on power supply.

BA400-series expander

not turned on. Turn on expander.

Power supply or module

failure. Call your Digital Services

representative.

System has power; AC

Present and DC OK

indicators lit; nothing

displays on console

terminal.

Console terminal off. Turn on console terminal.

Console terminal off

line. Put terminal on line as described

in terminal document.

Hold key activated. Deactivate hold key.

Console terminal cable

incorrectly installed. Make sure cable is installed

properly at both ends.

Console terminal setup

not done correctly. Reread setup instructions in

terminal manual.

Baud rate of system and

terminal do not match. Set terminal baud rate to match

system rate.

Power-Up Mode switch

on console module set to

Set that switch to Run (indicated

by arrow).

Terminal defective. Turn off terminal and turn it on

again. If it fails self-tests, call your

Digital Services representative.

If printer connected to

obtain copy of console

interaction, fault in

printer.

Turn off printer and turn it on

again. If it fails self-tests, call your

Digital Services representative.

Problem in CPU. Call your Digital Services

representative.

System has power; DC

OK indicator lit; nothing

displays on console

terminal; LED on

console module displays

E or F.

Problem in CPU. Call your Digital Services

representative.

Troubleshooting During Power-Up 1–3

Problem Possible Cause Corrective Action

Self-tests halt; error

message or error

summary displays on

console terminal.

System detected error

while running self-tests. Copy number following question

mark in error message or summary

and call your Digital service

representative.

Language Selection

Menu does not appear. Baud rate on console

terminal different from

baud rate on system.

Check that baud rate on console

terminal agrees with system rate.

Terminal does not

support multinational

character set (MCS).

Obtain terminal that supports

MCS, or use the default language

(English). If this is not a problem

continue.

1.2.2 General Problems During Boot Sequence

Problem Possible Cause Corrective Action

System returns to BOOT

prompt after 4 minutes. Sanity timer enabled on

DESQA module. Disable sanity timer as described

in DESQA Option Installation

Guide.

terminal. Break Enable/Disable

switch set to enable (up);

system in console mode.

To autoboot, set Break Enable

/Disable switch on console module

to disable (down). Reset system by

pressing Restart button on system

control panel. To boot manually

from console mode, use BOOT

device-name command.

>>>
