\section{The VAXstation 2000 and MicroVAX 2000 Systems}
|
|
|
|
The VAXstation 2000 and MicroVAX 2000 systems are mechanically
|
|
identical. Both come in the same style box, both use the same drives,
|
|
and both use the same mass storage expansion boxes. Also, both use
|
|
the same diagnostic tools for troubleshooting and repair. Once familiar
|
|
with troubleshooting one system, you'll be able to troubleshoot the other
|
|
if necessary. One major difference is the VAXstation 2000 is a single-user
|
|
system and the MicroVAX 2000 is a multiuser system. Another difference
|
|
is the VAXstation 2000 uses a video monitor while the MicroVAX 2000 uses
|
|
video terminals.
|
|
|
|
Both the VAXstation 2000 and the MicroVAX 2000 have three main pieces
|
|
of hardware. They are the System box, the hard disk expansion box, and
|
|
the tape drive expansion box. The System box can have a half-height RX33
|
|
floppy disk drive, a half-height RD32 hard disk drive, or both the RX33 and
|
|
the RD32. A full-height RD53 hard disk drive can be substituted for the
|
|
half-height drives in the System box. The hard disk expansion box comes with a
|
|
full-height RD53 hard disk drive. The tape drive expansion box comes with
|
|
a TK50 tape drive.
|
|
|
|

Figure 1-1 shows the front of the VAXstation 2000 and MicroVAX 2000
|
|
systems. There are three ways to differentiate between the two systems:
|
|
the medallion next to the power switch on the front, the DEC423 converter
|
|
on the back, or the system jumper position on the system module inside
|
|
the box.

\newpage
|
|
Figure 1-2 shows the rear view of the VAXstation 2000 and labels each
|
|
connector. A modem or a terminal can be connected to the 25-pin
|
|
communication port. A VR260 monochrome monitor can be connected to the
|
|
15-pin video port. A printer can be connected to the 9-pin printer port. The
|
|
ThinWire Ethernet port Supports IEEE 802.3 (Standard Ethernet) network
|
|
communications connections over the ThinWire Ethernet cable.
|
|

\newpage
|
|
|
|
|
|
Figure 1-3 shows the rear view of the MicroVAX 2000 and labels each
|
|
connector. Like the VAXstation 2000, the MicroVAX 2000 supports a modem
|
|
or a terminal on the 25-pin communication port. The MicroVAX 2000
|
|
supports the DECconnect strategy which uses the modified modular jack (MMJ)
|
|
6-conductor telephone type cable (DEC423 asynchronous protocol) for
|
|
connection to the terminals. The DEC423 Converter changes the 15-pin video
|
|
port and the 9-pin printer port (RS232 protocol) to three MMJ communication
|
|
ports. Port 1 on the DEC423 Converter is reserved for the console
|
|
terminal. Ports 2 and 3 can have either a terminal or a printer attached to
|
|
them. The operating system Software configures each port for either a terminal
|
|
or a printer. The ThinWire Ethernet port supports IEEE 802.3 (Standard
|
|
Ethernet) network communications connections over the ThinWire Ethernet
|
|
cable.

\section{Mass Storage Expansion Box for Both Systems}
|
|
|
|
Additional mass storage devices are contained in expansion boxes that look
|
|
very similar to the system box. Figures 1-4 and 1-5 show the front view of
|
|
the expansion boxes.
|
|
|
|
The hard disk expansion box contains an RD53 or RD54 hard disk drive.
|
|
The tape drive expansion box contains a TK50 tape drive and a controller
|
|
board. Each expansion box contains a power supply, a resistor load board
|
|
(to regulate the power supply), and the drive.
|
|

|
\fig{MA-0064-87}{Front View of the Tape Drive Expansion Box}
|
|
|
|
\newpage
|
|
|
|
Both expansion boxes connect to the system box through an expansion
|
|
adapter that attaches to the bottom of the system box. The expansion
|
|
adapter has three connectors on the back labeled ports A, B, and C. Port
|
|
A connects the tape expansion box to the system. Port B connects the hard
|
|
disk expansion box to the system. Port C is reserved for future options.
|
|
Figure 1-6 shows the back of a MicroVAX 2000 system box with an expansion
|
|
adapter.

\section{Options}
|
|
\subsection{Internal Memory Options}
|
|
|
|
Two additional memory modules are available for both systems. One is a
|
|
2-megabyte memory module and the other is a 4-megabyte memory module.
|
|
The memory module is located in the system box and is connected directly
|
|
to the system module.
|
|
|
|
\subsection{ThinWire Ethernet Option on MicroVAX 2000}
|
|
|
|
ThinWire Ethernet is an option on the MicroVAX 2000. It comes standard
|
|
on the VAXstation 2000. It adds the capability of connecting the system to
|
|
the DECnet through the ThinWire Ethernet network. The option consists
|
|
of a network interconnect module that is located in the system box and is
|
|
connected to the system module through two 40-conductor cables.
|
|
|
|
\section{FRU Locations}

\chapter{Testing and Troubleshooting}
|
|
|
|
\section{Introduction}
|
|
|
|
This chapter describes how to test and troubleshoot the VAXstation 2000
|
|
and the MicroVAX 2000 systems. Differences between the VAXstation 2000
|
|
and the MicroVAX 2000 are specifically identified in the text.
|
|
|
|
This chapter contains the following sections.
|
|
|
|
\begin{itemize}
|
|
\item How to use console mode: determining the console device, enter
|
|
ing console mode, exiting console mode, utilizing the diagnostic
|
|
console device, and where to find a list of the console commands.
|
|
\item How to run the diagnostic tests and interpret the error codes for
|
|
each test: power-up tests, self-test, and system exerciser.
|
|
\item How to troubleshoot all devices in the system.
|
|
\item How to use the utilities.
|
|
\end{itemize}
|
|
|
|
\section{Using Console Mode}
|
|
|
|
The VAXstation 2000 and the MicroVAX 2000 systems have two modes
|
|
of operation: program mode and console mode. Normal operation of the
|
|
VAXstation 2000 and the MicroVAX 2000 is in program mode, that is, with
|
|
the operating system controlling the system. Console mode allows the user
|
|
to control the system from the console terminal using the console com
|
|
mands described in Appendix B. Console mode is contained in ROM on
|
|
the system module.
|
|
|
|
Testing is done while in console mode. The System returns the \console
|
|
prompt when it is in console mode. Table 2-1 lists the prompts and the
|
|
mode of operation each prompt represents.
|
|
|
|

\hline
|
|
\end{tabularx}
|
|
\end{table}
|
|
|
|
\subsection{Determining the Console Device}
|
|
|
|
The console device for a VAXstation 2000 system is the keyboard (LK201)
|
|
and monitor (VR260) connected to the video port. The keyboard inputs
|
|
commands at 4800 baud and the monitor displays output from the video
|
|
circuits.
|
|
|
|
The console device for a MicroVAX 2000 system is the terminal (VT220 or
|
|
similar terminal) connected to connector 1 on the DEC423 converter. The
|
|
terminal operates at 9600 baud.
|
|
|
|
\subsection{Entering Console Mode}
|
|
|
|
Console mode is entered any time the CPU halts. The CPU can be halted
|
|
automatically or manually. A halt means that CPU control has passed
|
|
control from the operating system to the console mode program in ROM. If
|
|
the system halts the CPU, then the console mode program checks the
|
|
nonvolatile RAM (NVR) for user-defined instructions on how to handle the halt.
|
|
If you manually halt the CPU, the system enters console mode program
|
|
immediately without checking the NVR for instructions.
|
|
|
|
You can manually halt the CPU and enter console mode by one of the
|
|
following methods.
|
|
|
|
\begin{itemize}
|
|
\item HALT button -- Press the halt button. It is located next to the printer port
|
|
on the back of the System box. The \console prompt is displayed when
|
|
ready for console commands.
|
|
\item BREAK key -- Press the BREAK key on the diagnostic console device
|
|
that is connected to the printer port with the BCC08 cable. The \console
|
|
prompt is displayed when ready for console commands.
|
|
\end{itemize}
|
|
The system automatically halts the CPU for the following reasons.
|
|
\begin{itemize}
|
|
\item After power-up testing -- If the default recovery action is halt, the system
|
|
automatically halts the CPU and enters console mode after power-up
|
|
tests are complete. See Section 2.5.4 for information on setting the
|
|
default recovery actions.
|
|
\item For a boot failure -- If the system fails to boot properly, the system
|
|
automatically halts the CPU and enters console mode. See Section 2.5.2
|
|
for information on setting the default boot device.
|
|
\item On a system error -- If the CPU detects a severe corruption of its oper-
|
|
ating environment, it halts and reads the default recovery action in the
|
|
NVR. The default recovery action can be restart, boot, or halt. When
|
|
it is restart and the restart fails, then the system automatically tries to
|
|
boot the operating system software. If the boot fails, the CPU halts and
|
|
enters console mode. When the default recovery action is boot and the
|
|
boot fails, the CPU halts and enters console mode. When the default re
|
|
covery action is halt, the CPU unconditionally halts and enters console
|
|
mode.
|
|
\end{itemize}
|
|
|
|
One other way to halt the CPU is when the operating system software
|
|
executes a halt instruction. The CPU then reads the default recovery action in
|
|
the NVR and acts on it as described above.
|
|
|
|
\subsection{Exiting Console Mode}
|
|
|
|
Console mode is exited by typing one of the following console commands.
|
|
|
|
\begin{itemize}
|
|
\item BOOT -- This command initializes the CPU and boots the operating
|
|
system software from the device specified. If no device is specified, the
|
|
system searches each on-line device until the operating system software
|
|
|s found. The boot command starts the system similar to when power
|
|
is turned on except that the power-up tests are not run. If the system
|
|
attempts to boot over the net (ESA0) and no software is available on
|
|
another node, the system keeps looking for the software indefinitely.
|
|
If a boot message for the operating system software does not appear
|
|
shortly after the Ethernet boot message (ESA0) is displayed, then you
|
|
must press the halt button to abort the Ethernet boot. If you still need
|
|
to boot over the Ethernet, make sure the node with the operating sys-
|
|
tem software is operating normally and the software is loaded. Run the
|
|
Ethernet loopback Utility (TEST 90) to check the networking capability
|
|
of the system if the Ethernet boot continues to fail.
|
|
|
|
When a boot is invoked using this boot command, you can specify
|
|
several boot command flags by bit encoding the flags in a flag word
|
|
specified with the /R5: qualifier. These command flags are listed in
|
|
Paragraph 2.5.3.
|
|
|
|
\item CONTINUE -- This command instructs the CPU to continue the
|
|
operating system software at the address contained in the program counter
|
|
(PC). This command starts up the operating software where it was halted
|
|
provided no console test commands were run. Running a test command
|
|
alters the PC and memory so that the operating system software cannot
|
|
be started properly by entering the continue command. If a test com-
|
|
mand was entered, use the boot command to start the operating system
|
|
software. The continue command is similar to the start command. The
|
|
start command can specify the address to Start the operating software
|
|
and the continue command has the operating software continue where
|
|
it left off.
|
|
|
|
\item START -- This command Starts the operating System Software at a
|
|
specified address. If no address is given, the contents of the PC are used.
|
|
However, running a test command alters the PC and memory so that the
|
|
operating system software cannot be started properly by entering the
|
|
start command. If a test command was entered, use the boot command
|
|
to start the operating system software.
|
|
|
|
\end{itemize}
|
|
|
|
\subsection{Diagnostic Console Device}
|
|
|
|
There is a diagnostic console device available on the VAXstation 2000. The
|
|
MicroVAX 2000 can use this device if the DEC423 Converter is removed.
|
|
|
|
The diagnostic console device can be utilized by connecting a terminal (such
|
|
as the VT100 or VT220) to the printer port with the special BCC08 cable.
|
|
The terminal operates at 9600 baud. Field service technicians can use this
|
|
terminal as a diagnostic tool to isolate a problem in the normal console
|
|
device.
|
|
|
|
To use this diagnostic console device you must turn off power, connect the
|
|
BCC08 cable to the printer port and terminal, and then turn power back on.
|
|
The diagnostic console device now controls the system. The normal console
|
|
monitor displays video test patterns on the VAXstation 2000 when the video
|
|
circuits are tested. The normal console keyboard does not operate.
|
|
|
|
\subsection{Console Commands}
|
|
|
|
Console commands are listed in Appendix B.
|
|
\newpage
|
|
\section{Testing}
|
|
|
|
Testing procedures on the VAXstation 2000 and the MicroVAX 2000 systems
|
|
are almost identical. The differences between the systems are explained
|
|
where applicable. All diagnostic tests are ROM-based and testine is done
|
|
while in console mode. Tests are executed in either of two ways:
|
|
|
|
\begin{itemize}
|
|
\item Automatically -- When power is turned on the power-up tests begin.
|
|
\item Manually -- By entering one of the console test commands on the
|
|
console terminal. See Appendix A for a complete listing of the test commands.
|
|
\end{itemize}
|
|
|
|
\subsection{Power-up Tests}
|
|
|
|
Power-up tests run each time the system power is turned on. Power-up
|
|
testing consists of a sequence of tests executed for each device installed in
|
|
the system. The test number of each device is listed on the power-up screen
|
|
display as the device is tested. Figure 2-1 shows an example of the power-
|
|
up screen display. The first line indicates the CPU name (KA410-A) and the
|
|
ROM version (V1.0). The test numbers are listed next in descending order
|
|
from the first test, F, to the final test, 1. TEST F will have an underscore
|
|
after it on the MicroVAX 2000 to indicate that TEST F was not run. Note in
|
|
Figure 2-1 that tests 4, 3, 2, and 1 have an underscore (\_) immediately after
|
|
them. This underscore indicates that there is no option device installed for
|
|
that test; thus, no tests are done. TEST F has an underscore after it on the
|
|
MicroVAX 2000 systems because the monochrome video circuits are not
|
|
used by the MicroVAX 2000. No other test numbers can have underscores
|
|
after them. An asterisk (*) after TESTS 4 through 1 indicate that an option is
|
|
installed, but its ROM is destroyed and the Option device must be replaced.
|
|
Only TESTS 1 through 4 can have an asterisk after them. Figure 2-2 lists
|
|
the symbols that can appear in between the tests and what they indicate.
|
|
|
|
\begin{figure}[H]
|
|
\caption{Example of Power-up Tests Screen Display}
|
|
\begin{verbatim}
|
|
KA410-A V1.0
|
|
F...E...D...C...B...A...9...8...7...6...5...4_..3_..2_..1_..
|
|
\end{verbatim}
|
|
\end{figure}
|
|
|
|
Figure 2-2 lists the definitions of the symbols that appear between the test
|
|
numbers in the power-up test countdown.
|
|
|
|
\begin{figure}[H]
|
|
\caption{Power-up Symbols Defined}
|
|
\begin{verbatim}
|
|
... Device tested successfully or has a soft error
|
|
?.. Device has a hard error
|
|
_.. Device not installed or not tested
|
|
*.. Device installed but its ROM is destroyed
|
|
\end{verbatim}
|
|
\end{figure}
|
|
|
|
If any hard errors (errors that indicate the device must be replaced for
|
|
proper operation) are found during power-up testing, a question mark is
|
|
placed after the failing test number during the countdown sequence. An
|
|
error summary of all errors detected is listed after the power-up sequence
|
|
is complete. Two question marks in the error summary indicate a hard error.
|
|
Error codes that indicate the status or soft errors do not put a question mark
|
|
after the failing test number in the sequence, but do list the error code in the
|
|
error summary. Figure 2-3 shows the power-up screen display with a hard
|
|
error found in TEST F and a soft error found in TEST E. The error summary
|
|
for each failed device is displayed before the boot sequence is started.
|
|
However, the screen usually scrolls so fast when the system starts to boot
|
|
that you may not be able to see what the error summary contained (if there
|
|
was an error summary). To see what errors the power-up tests found, press
|
|
the halt button and enter TEST 50 on the console terminal. TEST 50 is the
|
|
command for bringing up the configuration table. The configuration table
|
|
is created during power-up testing. This configuration table contains all of
|
|
the error codes listed in the power-up error summary as well as error codes
|
|
for all devices installed in the system. The error codes in the configuration
|
|
table are updated every time self-test is run. See Paragraph 2.5.1 for an
|
|
explanation of how to use the configuration table.
|
|
|
|
Each error summary consists of one or two question marks, a test number,
|
|
the ID number of the failed device, and an eight-digit error code. For ex-
|
|
ample, in Figure 2-3, the first line of the error summary shows a hard error
|
|
for TEST F, a device ID number of 00B0, and an error code of 0001.F002.
|
|
The second line shows a soft error for TEST E, a device ID of 0040, and an
|
|
error code of 0000.0005. Section ( 2.3.1.1) describes the error codes.

If there is a fatal error in the NVR during power-up testing, the system stops
|
|
testing the other devices and displays ?14 TOY ERR on the screen. When
|
|
this happens, the only way to determine the cause of the problem is by
|
|
viewing the LEDs on the keyboard. One of the LEDs will be lit to indicate
|
|
the failing module. Table 2-2 lists the LEDs and which module has failed.
|
|
|
|

|
|
Once power-up testing is complete and no fatal or hard errors are found, the
|
|
system boots the operating system software. Both the VAXstation 2000 and
|
|
the MicroVAX 2000 boot the operating system software the same. The only
|
|
difference between the two is that the VAXstation 2000 clears the console
|
|
screen before it boots and the MicroVAX 2000 does not. If a default boot
|
|
device is loaded in the NVR, the system boots off of that device. If no
|
|
default device is loaded in the NVR, the system searches every on-line
|
|
storage drive for the operating software. DUA2 is searched first if a floppy
|
|
diskette is loaded. Otherwise, it is not searched at all. The hard disks are
|
|
searched next, DUA0 then DUAl. MUA0, the tape drive, is checked after
|
|
the hard disk drives if it is installed and a cartridge is loaded. Finally, the
|
|
system searches the Ethernet network for the software and ESA0 is listed
|
|
on the screen. The system continues to search the Ethernet network until
|
|
the operating system software is found.
|

\subsubsection{Power-up Test Error Codes}
|
|
|
|
The power-up test error codes indicate status and/or error information. Any
|
|
errors found by power-up tests are listed in the error summary after the
|
|
power-up test countdown sequence. This summary, if any, gives you a brief
|
|
summary of the errors. Table 2-3 lists the test numbers and the devices that
|
|
are tested during that particular test. To look at the complete list of devices
|
|
and the status of that device, you must display the configuration table. The
|
|
configuration table lists every device in the system and also lists the results
|
|
of the self-test and power-up tests and is updated each time self-test is run.
|
|
The error codes for each device in the configuration table are explained in
|
|
the troubleshooting section for that individual device. Remember that the
|
|
configuration table contains the results of the self-test and power-up tests
|
|
and not the results of the system exerciser. Figure 2-4 shows an example
|
|
of the configuration table and for an explanation of the configuration table,
|
|
see Paragraph 2.5.1.
|
|
|
|

\end{figure}
|
|
|
|
The most common good error code is 0000.0001. There are, however, some
|
|
devices that use the first four digits in the error code to indicate the status
|
|
of the device and the last four digits to indicate the error found on the
|
|
device. The memory (MEM) error code, for instance, contains 0002.0001
|
|
which indicates two megabytes of memory is available (0002.) and no error
|
|
found (.0001). On devices like these, the last four digits always indicate
|
|
.0001 as a good (non-error) indication.
|
|
|
|
Some error codes indicate no error at all and give a status of the device
|
|
such as the clock (CLK) which shows that the date and time has not been
|
|
set. This is not an error, just a status of the clock circuits.
|
|
|
|
Any error code other than 0000.0001 on the MONO, MM, FP, IT, or SYS
|
|
devices indicates a hard error and that device must be replaced for proper
|
|
operation of the system. The other devices such as CLK, NVR, DZ, MEM,
|
|
HDC, TPC, and NI may have a status or a soft error message in the error
|
|
codes and may still operate normally.
|
|
|
|
See the troubleshooting procedures section (Paragraph 2.4) for each device
|
|
to determine whether or not the error code indicates a fault or a status for
|
|
the device.
|
|
|
|
\subsection{Self-test}
|
|
|
|
Self-test allows you to test every device again individually, a few at a time,
|
|
or all of them sequentially just like power-up tests. To individually test a
|
|
device, enter TEST \# where \# is the test number of the device you want
|
|
tested. Table 2-3 lists the test numbers and the devices tested by those
|
|
numbers. Figure 2-5 shows an example of running self-test successfully on
|
|
the disk controller.
|
|
|
|
\begin{figure}[H]
|
|
\caption{Example of Running Self-test on the Disk Controller}
|
|
\begin{verbatim}
|
|
>>> TEST 7
|
|
7...
|
|
>>>
|
|
\end{verbatim}
|
|
\end{figure}
|
|
|
|
To test a group of devices, enter TEST followed by the test number of the
|
|
first device to be tested and then the test number of the last device to be
|
|
tested. Figure 2-6 shows an example of testing a group of devices. In Figure
|
|
2-6, all tests between C and 4 are tested successfully. Note that you cannot
|
|
pick and choose which devices to test between C and 4, all tests between
|
|
C and 4 are tested when entered as a group.
|
|
|
|
\begin{figure}[H]
|
|

|
|
>>>
|
|
\end{verbatim}
|
|
\end{figure}
|
|
|
|
To test all devices, enter TEST F 1. The MicroVAX 2000 skips over the
|
|
MONO video test (TEST F) since it does not use the video circuits.

\subsubsection{Self-test with Loopback Connectors}
|
|
|
|
Customer mode self-test does not test the drivers or the lines of the serial
|
|
line conroller (DZ) since loopbacks are not used. Run self-test in field
|
|
service mode to test the DZ drivers by installing the loopback connectors on
|
|
the back of the System. Follow one of the procedures below.
|
|
|
|
To test the DZ on VAXstation 2000, install a loopback (p/n 29-24795) on
|
|
the 25-pin communication port and a loopback (p/n 29-24794) on the 9-pin
|
|
printer port. Run TEST C. You cannot use loopback connectors if you are
|
|
using the diagnostic console device with the BCC08 cable on the printer
|
|
port since there is no loopback connector for the video port.
|
|
|
|
To test the DZ on MicroVAX 2000, install a loopback (p/n 29-24795) on the
|
|
25-pin communication port and install an MMJ loopback on both ports 2
|
|
and 3. Run TEST C.
|
|
|
|
\textbf{NOTE:} \textit{The ThinWire Ethernet port on the back of the
|
|
system box must be terminated properly when running diagnostics on the
|
|
network option (TEST 1) othetwise an error code of 0000.7001 or greater
|
|
is listed in the configuration table.}
|
|
|
|
\subsubsection{Self-test Error Codes}
|
|
|
|
Figure 2-7 shows how an error is displayed if found during self-test. This
|
|
example shows an error on the disk controller during self-test. The 84 FAIL
|
|
indicates an error was found on the device tested. You must display the
|
|
configuration table (TEST 50) after self-test is complete to see the error code,
|
|
if there is an error during self-test, since the error codes do not appear on
|
|
the screen. The configuration table lists every device in the system, fists the
|
|
results of the self-test and power-up tests, and is updated each time self-test
|
|
is run. The error codes for each device in the configuration table are
|
|
explained in the troubleshooting section for that individual device. Remember
|
|
that the configuration table contains the results of the self-test and power-up
|
|
tests and not the results of the system exerciser. See Paragraph 2 5 1 for an
|
|
explanation of the configuration table.
