\subsection{NVR -- Non-Volatlle RAM Troubleshooting Procedures}
You can troubleshoot the NVR circuitry in either customer mode or field
service mode. Both modes test the NVR circuits the same.
\subsubsection{Self-test}
To run self-test, enter TEST D. Any error code other than 0000.0001 in
dicates a fault in the NVR. An error code of 0000.0005 indicates that the
battery charge is below the normal voltage level. If the battery is low, al-

\subsection{DZ -- Serial Line Controller Troubleshooting Procedures}
You can troubleshoot the DZ in either customer mode or field service mode.
The difference between the two modes is that field service mode tests the
serial line drivers on the system module and customer mode does not.
\subsubsection{Self-test}
To run customer mode self-test on either the VAXstation 2000 or the
MicroVAX 2000, enter TEST C. Loopback connectors must not be installed
when in customer mode. Loopback connectors must, however, be installed
to run field service mode diagnostics. Any error code other than 0000.0001
indicates a fault in the DZ controller. You must replace the system module
to fix the problem. If you are using the diagnostic console device, any error
code other than 0000.4001 indicates a fault in the DZ controller.
\textbf{VAXstation 2000}
To run self-test in field service mode 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. Enter TEST C. If the error code is not
0000.0001, check to see if the loopbacks are still connected. Reconnect
them, if necessary, and test again. Replace the system module if the error
still exists. Loopbacks cannot be used to test the DZ controller when the
console device is the diagnostic console with the BCC08 cable since there
is no loopback for the video port.
\textbf{MicroVAX 2000}
To run self-test in field service mode on MicroVAX 2000, install a loop
back (p/n 29-24795) on the 25-pin communication port and install an MMJ
loopback on both ports 2 and 3. Enter TEST C. If the error code is not
0000.0001, check to see if the loopbacks are still connected. Reconnect
them, if necessary, and test again. Replace the system module if the error
still exists.
\subsubsection{System Exerciser}
To run the customer mode system exerciser on either the VAXstation 2000
or the MicroVAX 2000, enter TEST 0. The results are displayed on the video
screen as the tests are completed.
\textbf{VAXstation 2000}
To run the field service mode system exerciser 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. Enter TEST 101. If you are using the
diagnostic console device, you will get errors on the DZ line since there is
no loopback for the video port. Any error code other than 0X00.0001, where
X is the serial line being used for the console device, indicates a fault in
the DZ controller. You must replace the system module to fix the problem.
If the console device is connected to the video port on VAXstation 2000,
then you will see a 0 (zero) in the X position. If the console device is the
diagnostic console device with the BCC08 cable on the printer port, then
you will see a 3 in the X position. If the error code is not 0X00.0001, check
to see if the loopbacks are still connected. Reconnect them, if necessary,
and test again. Replace the system module if the error still exists.
\textbf{MicroVAX 2000}
To run the field service mode system exerciser 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. Enter TEST 101 or TEST 102. Any
error code other than 0X00.0001, where X is the serial line being used for
the console device, indicates a fault in the DZ controller. You must replace
the system module to fix the problem. With the console device connected to
port 1 on the MicroVAX 2000, you will see a 0 (zero) in the X position. If the
error code is not 0X00.0001, check to see if the loopbacks are still connected.
Reconnect them, if necessary, and test again. Replace the system module
if the error still exists. If the error still exists after replacing the system
module, replace the DEC423 converter on the back of the system box.
\subsection{MEM -- Memory Troubleshooting Procedures}
You can troubleshoot memory in either customer mode or field service
mode. Both modes test the MEM circuits the same. These procedures are
for both VAXstation 2000 and MicroVAX 2000.
\subsubsection{Self-test}
To run self-test, enter TEST B. Any error code other than 000X.0001, where
X is the size of memory (megabytes) in the system, indicates a fault in the
memory circuits. The problem could either be with the system module or
the memory Option module. To determine which module is at fault go to
\hyperlink{subsubsection.2.5.1.2}{Paragraph 2.5.1.2}.
\subsubsection{System Exerciser}
To run the system exerciser, enter TEST 0 for customer mode or TEST 101
for field service mode. \figref{2-9} shows what the MEM system exerciser
error code indicates. The status portion of the code indicates the number
of pages tested during the last test pass (1 page = 512 bytes) if there were
no errors found.

\subsection{MM -- Memory Management Unit Troubleshooting Procedures}
You can troubleshoot the memory management (MM) circuitry in either
customer mode or field service mode. Both modes test the MM circuits the
same.
\subsubsection{Self-test}
To run self-test, enter TEST A. Any error code other than 0000.0001
indicates a fault in the memory managment circuits. You must replace the
system module to fix the problem.
The system exerciser does not display the status of the MM circuits. The
MM circuits are not directly tested but are tested through the testing of other
circuits.
\subsection{FP -- Floating Point Unit Troubleshooting Procedures}
You can troubleshoot the floating point (FP) circuitry in either customer
mode or field service mode. Both modes test the FP circuits the same.
\subsubsection{Self-test}
To run self-test, enter TEST 9. Any error code other than 0000.0001 indicates
a fault in the floating point circuits. You must replace the system module
to fix the problem.
The system exerciser does not display the status of the FP circuits. The FP
circuits are not directly tested but are tested through the testing of other
circuits.
\subsection{IT -- Interval Timer Troubleshooting Procedures}
You can troubleshoot the interval timer (IT) circuitry in either customer
mode or field service mode. Both modes test the IT circuits the same.
\subsubsection{Self-test}
To run self-test, enter TEST 8. Any error code other than 0000.0001 indicates
a fault in the timing circuits. You must replace the system module to fix the
problem.
The system exerciser does not exercise the IT circuits.
\subsection{HDC -- Disk Drives and Controller Troubleshooting Procedures}
You can troubleshoot the disk controller and drives using self-test and the
system exerciser. These diagnostics test the disk controller on the system
module and also test the drives connected to the controller. There is a max-
imum number of three drives that can be supported in either a VAXstation
2000 or a MicroVAX 2000. The three drives are labelled DUA0, DUA1, and
DUA2. DUA0 will always be the hard disk drive (RD) located in the system
box. DUA0 can be a full-height or a half-height drive. DUA1 will always be
the hard disk drive (RD) located in the expansion box. DUAI communicates
to the system module through port B on the expansion adapter; thus allow-
ing you to isolate DUA1 during testing, if necessary, without opening the
system box. DUA2 will always be the half-height floppy disk drive (RX33)
and will only be located in the system box. If DUA0 is a full-height drive,
then a floppy disk drive cannot be installed because of lack of space in the
system box. The disk controller labeis any drive off-line that is not installed.
It also labeis DUA2 off-line if a floppy diskette is not properly loaded.
\subsubsection{Self-test}
To run self-test on the HDC, enter TEST 7. Self-test gives a quick status
of the disk controller on the system module and the drives. You can run
self-test in either customer mode or field service mode since both modes
test these devices the same. The error code for the disk controller (HDC in
the configuration table) contains the test results of the disk controller and
the status of the three drives. \figref{2-10} shows how the error code is
broken into five segments: status of DUA2, DUA1, DUA0, tape controller,
and the error code if a hard error is found. The power-up error code is the
same as the self-test error code.

\end{ttfig}
Each drive has the same set of error codes. These codes are listed in
\tabref{2-6}. All odd-numbered error codes are soft errors or a status. All
even-numbered error codes (including A and F) are hard errors. The last four
digits of the error code repeat the first four digits if a hard error is found on
the disk controller. Otherwise, the last four digits contain 0001 to indicate
no errors or soft errors.

the floppy diskette is not the problem, replace the system module and then
replace the floppy disk drive if replacing the system module did not fix the
problem. \\
A & Drive select timeout error. Drive failed. Replace the drive first. Replace
the system module if the problem is not fixed after replacing the drive. \\
F & Untested -- Drive was not tested because of a hard error found on the disk
controller. For example, FFF8.FFF8 indicates an error on the disk controller
and no drives were tested. Replace the system module. \\
\hline
\end{tbl}
If any error (except 7 and F) appears for any drive, check the drive for
power and check the cables for a good connection. If the error still exists,
the problem is either in the drive, in the cables, in the system module, or in
the disk interface module located in the expansion adapter. If, for example,
you replace one of the disks to fix an error code and the error still exists,'
replace the system module. If the system module does not fix the problem
replace the disk interface module.
\subsubsection{System Exerciser}
Start the system exerciser by entering TEST 0 for customer mode or install
the 25-pin loopback on the communications port and enter TEST 101 for
field service mode. The customer mode system exerciser does not exercise
the disks as thoroughly as the field service exerciser. The field service
system exerciser performs a complete read/write test on all drives and also
performs a data transfer test between the disk controller and one of the
drives.
The results of the system exerciser are displayed on the screen after the
first test pass of each device tested and again after all devices have been
run concurrently. \figref{2-11} shows the system exerciser display for the
disk controller (HDC). There is one line for the controller Status and one
line for each drive connected to the controller. A drive that is not installed
or is off-line is not listed in the display. For example, no diskette in DUA2
or an unformatted diskette in DUA2 labeis DUA2 as off-line and no display
for DUA2 is listed. If there are two question marks on the controllers line,
replace the system module. If there is a single question mark on the drive's
line, there is a soft error in the drive and the drive may operate normally.
Two question marks on the drive's line indicate a hard error in the drive
or an error in the controller. You must replace one or both to fix the error.
Two question marks for DUA2 may also indicate bad media on the floppy
diskette.

\subsubsection{Troubleshooting the Hard Disk Drive Expansion Box}
Troubleshoot the hard disk in the expansion box (DUA1) using self-test and
the system exerciser. However, if the diagnostic tests indicate an error on
DUA1, perform the steps in the following procedure.
\begin{enumerate}
\item Check to make sure the expansion box has power to it and it is switched on.
\item Check to make sure the hard disk cable is properly connected to port
B on the expansion adapter and the back of the expansion box.
\item Run the tests again and if the status code shows DUA1 to be off-line,
troubleshoot the power supply in the expansion box.
\item Disconnect the cable from port B on the expansion adapter and run
self-test (TEST 6). If any status other than the off-line indication (7) or
the not tested indication (F) shows up in the status code for DUA1, then
replace the disk controller on the system module.
\item If the status code does show that DUA1 is off-line after disconnecting
it from port B, check the drive select jumpers on DUA1 for proper
positioning. Refer to \hyperlink{subsubsection.2.4.9.4}{Paragraph 2.4.9.4}
below for proper drive select jumper settings.
\item If the drive select jumper is set properly, replace DUAl in the disk
expansion box. Always replace the drive's device electronics board
before replacing the whole drive.
\end{enumerate}
\subsubsection{Drive Select Jumper Settings on Disk Drives}
DUA0 -- Refer to \figref{2-12} to set the drive select jumper on an RD32 in
the system box. Refer to \figref{2-13} to set the drive select jumper on an
RD53 in the system box.
DUA1 -- Refer to \figref{2-13} to set the drive select jumper on an RD53 in
the expansion box.
DUA2 -- Refer to \figref{2-14} to set the drive select jumper on an RX33 in
the system box.

\subsection{TPC -- Tape Drive Controller Troubleshooting Procedures}
You can troubleshoot the tape drive Controller on the system module and
the tape drive controller in the expansion box using self-test or the system
exerciser. The tape drive expansion box has an internal self-test to
troubleshoot the TK50 tape drive as described in \hyperlink{subsubsection.2.4.10.3}{Paragraph 2.4.10.3}.
These troubleshooting procedures assume that only one tape expansion box
is connected to the tape port (port A) on the expansion adapter. Although
the diagnostic firmware located in ROM supports up to seven devices on
port A of the expansion adapter, we will only cover how to troubleshoot one
tape expansion box since the VMS and ULTRIX operating systems support
only one tape expansion box on either system. Also, the tape expansion
box must be configured for ID address 1 on the tape port.
\subsubsection{Self-test}
To run self-test, enter TEST 6. Self-test gives a quick status of the tape
controller on the system module and also the tape drive expansion box
connected to the tape controller via port A of the expansion adapter. You
can run self-test in either customer mode or field Service mode since both
modes test these devices the same. Enter TEST 50 to see the results of the
self-test. The TPC error code contains the test results of the tape controller
on the system module and the tape drives connected to port A on the
expansion adapter. \figref{2-15} shows how the TPC error code is broken
into five segments: ID addresses of devices connected to the tape port,
ID addresses of the devices that tested successfully, two possible cause
indicators, and a status of the tape controller.
\begin{ttfig}{2-15}{TPC Power-up and Self-test Error Code}

| 80 = ID Address 7
|
`---------> ID Address (shown above) of the tape

\end{ttfig}
A status code of 0000.4001 indicates a good status for the tape controller
when no devices are connected to port A. If there is a tape expansion box
connected to port A and the status code is 0000.4001, then the controller
does not recognize it or it is not powered up.
If the second two digits of the status code shown in \figref{2-15} (good
devices) do not match the first two digits (connected devices), then there
is a communication problem between the tape expansion box and the sys-
tem. Disconnect the cable from port A on the expansion adapter and run
self-test again. If the status code for TPC now contains anything other than
0000.4001, replace the system module. Otherwise, if the status code is
0000.4001, reconnect the cable to port A and make sure the tape expan
sion box is powered up. Run self-test again. If the status code for TPC
is not 0202.0001 after reconnecting the cable, run the system exerciser to
thoroughly test the tape controller and the tape expansion box. If the error
code is 0202.0001 after reconnecting the tape expansion box, the tape Con
troller and the expansion tape box are operating properly. Note that there
may be more than one tape expansion box on systems that run an operating
system other than VMS or ULTRIX. This means that the status code may be
0606.0001 for two devices at ID address 1 and 2 or FEFE.0001 for all seven
devices connected to the tape port. However, if the system does use VMS
or ULTRIX, the tape expansion box at ID address 1 is the only device VMS
and ULTRIX can communicate with.
\subsubsection{System Exerciser}
Start the system exerciser by entering TEST 0 for customer mode or install
the 25-pin loopback on the communications port, load the COMPACTape
cartridge with the special-key into the TK50, and enter TEST 101 for field
Service mode. The customer mode system exerciser does not exercise the
tape controller as thoroughly as the field Service exerciser. The field Service
mode system exerciser performs a complete read/write test on the TK50
tape drive and also performs a data transfer test while the customer mode
system exerciser does not test the TK50 tape drive at all.
The system exerciser runs a first pass test on MONO (VAXstation only), DZ,
MEM, and HDC before it runs the first pass test on the TPC. The first pass
test on the TPC tests the tape controller on the system module and checks
the tape port for the presence of a tape expansion box only if the tape Con
troller is operating properly. If the tape controller on the system module
tests bad, the error code for the tape controller lists an error and the tape
port is not checked for the presence of the tape expansion box. The first
pass test of the TPC does not perform any diagnostics or data transfer tests
on the tape expansion box. The first pass test only checks whether or not the
tape expansion box is there and whether or not it can communicate over the
tape port to the tape controller. Complete data transfer and read/write (field
Service mode only) testing is done on subsequent test passes. For exam-
ple, in field Service mode with the Special keyed COMPACTape cartridge
installed, the error code for the tape expansion box shows that the TK50 is
not writeable (1100.0001) during the first pass. However, the second pass
shows that the TK50 is writeable (1300.0001) as long as the cartridge has a
good Special key on it and the tape expansion box is operating properly.
So you must wait for the system exerciser to complete at least two passes
on the TPC to see if the tape expansion box is operating properly.
\figref{2-16} shows the system exerciser display for the TPC. There is one
line for the status of the tape controller on the system module and one line
for each tape expansion box connected to the tape port if it is powered
up. The status of the tape controller is next to the TPC mnemonic (first
line) and the status of the tape expansion box is listed under the status of
the controller. An easy way of determining if any errors are detected is by
looking for the question marks in the left column. If there are any question
marks on the tape controllers status line, the tape controller is faulty and
the error code identifies the problem. Refer to \tabref{2-9} to decifer the tape
controllers error code and determine how to fix the problem. If there are
any question marks on the tape expansion box's status line, the problem
could be in either the tape expansion box, the tape expansion box cable, or
the tape controller on the system module. An error that is listed in the tape
expansion box's error code may be a data transfer error and thus does not
isolate the problem to the tape expansion box; it may still be in the tape
controller on the system module. Refer to \tabref{2-10} to decifer the tape
expansion box's error code and determine how to fix the problem.
If errors are detected with the TPC, disconnect the tape expansion box cable
from port A on the expansion adapter and run the test again. This procedure
isolates the tape expansion box from the system box. If any errors appear
in the tape controllers error code, the problem is with the tape controller
and the system module must be replaced. Otherwise, the error is in the
expansion box and you must run the internal self-test on the expansion box
as described below.

The X position indicates the tape drive that was used for data transfer testing. This number should
be 1 if a tape expansion box is connected to the system and it is powered up. This number should be
8 if no tape expansion box is connected or if it is turned off. An F will always be in this position
during the first pass of the exerciser. If the P is still in this position after the first pass is complete, a
fatal error is detected in the tape controller on the system module and the tape expansion box is not
tested.
\\
0X00.0001 & The X indicates a data transfer error if X is anything other than zero. &
Replace the system module. If the error still exists, replace the TK50 tape drive.
Then if the error code still exists, replace tbe TZK50 controller board.
\\
00XX.0001 & The XX indicates the number of data transfer errors detected.
Make a note of the tape drive used for the data transfer test. &
Run the exerciser again. Was the same drive used for the transfer test? If yes, and the number of
transfer errors are the same (or close to the same), replace the system module. If no, and the number
of transfer errors are zero or considerably less than before, replace the TK50 drive that was originally
used for the transfer test. If the error code still exists, replace the TZK50 controller board.
\\
0000.XXX1 & Controller error if any X is anything other than zero. &
Replace the system module.
