Check all boxes for external damage (dents, holes, smashed corners).

Notify the customer of any damage and list it on the Labor Activity Reporting System
(LARS) report form (Figure 1-1 ). Include a note to clarify the extent of the damage.

Make sure all containers are sealed.
NOTE
Any opened packages or cabinets should be called to
the attention of the customer and documented on the
LARS report.

Remove the shipping/ accessory list in the "Open Me First" box and inventory the contents
of all boxes against the shipping list.

Notify the branch manager or branch supervisor of any missing or incorrect items. Advise
the customer to contact the carrier about any missing items.

Inform the branch service manager of the DIG IT AL Traffic and Shipping Department if the
carrier does not have the missing items.

Cut and remove strapping from the cabinet boxes.

Remove the cabinet boxes.

Install four leveling feet (Figure 1-2) on the cabinets using a 9/16-inch wrench. Use the hex
nuts and washers that were removed with the four red shipping brackets.

1.2 CABINET DISASSEMBLY PROCEDURES
The cabinets must be partially disassembled prior to being integrated into a system.

"START"

NOTE
Unless you are testing a DR780 configured into a
two-CPU two-DR780 link, do not run diagnostics
ESDFE or ESDFG.

Run the following diagnostic programs:
ESDFA-

This is a standalone diagnostic package that uses its own microcode to test all DR 780
registers, the data path, and the DUP microsequencer.

ESDFB -

This is a standalone diagnostic package that uses its own microcode to test the functions of the DR 780 Control Board (DCB) and DR 780 microprocessor board (DUP).

ESDFC -

This is a standalone diagnostic package that uses its own microcode to test all functions used by the DR780 silo module (DSM), and the out of sequence logic on the
DR 780, located on the DSC and DCB.

ESDFD-

This program exercises the DR 780 with the standard DR 780 microcode. It is a standalone diagnostic package that checks the correct functioning of the DR 780 by performing actual data transfers with different block sizes, and in different error and
nonerror modes. The exercising of the DR 780 is performed with all command types,
with and without data chaining. ESDFD loads a copy of WCS file into the DR780 so
it can be used to run the ESDFF error program.

ESDFE-

This diagnostic package is a standalone diagnostic used to test the CPU-to-CPU function of the DR780 by using two DR780s. ESDFF cannot be operated if the microcode
has not been loaded.

ESDFF -

This diagnostic package is similar to ESDFD, but it tests the DR 780 in user mode.

ESDFG -

This package is similar to ESDFE, but it tests the DR 780 in user mode.

ESDFH -

This package is used to start the far end device in conjunction with diagnostic package ESDFE and is used in nonuser mode only.

6-8

Before loading the diagnostic, be sure the following connections are made:
•

Jumper E04Ml to E04Rl of the DR780 backplane

•

Jumper EOEM2 to EOER2 of the DR780 backplane

•

Configure jumpers Wl through W4 for the correct TR level (refer to Engineering Drawing
E-UA-DR 780-0-0, sheet 2).

•

Make sure the correct connection is made on backplane for the TR level selected in step 3
(refer to wirewrap table on Engineering Drawing E-UA-DR780-0-0, sheet 2).

•

Configure jumpers W5 and W6 for BR of six, W5 IN, W6 OUT.

•

Make sure that W7 and W8 are not installed on the DR 780 backplane.

•

Disconnect the DR780 from the customer's device if the DR780 is not part of a DR780-toDR780 link.

Use the following procedure to load the diagnostic program into the system:
1.

Put the VAX-11 /780 in a stable, halted condition.

Initialize and unjam the SBI via the console commands:
INIT
UNJAM

Load the diagnostic supervisor ESSAA.EXE using the command BOOT or LOAD ESSAA.EXE/ST:FEOO (from the diskette) or RUN ESSAA (for user mode diagnostic).

Load the diagnostic program by its designation letters, i.e., LOAD ESDFA (ESDF A is the
program ID).

Attach the device to be tested; ATTACH DR780 SBI (UNIT#) (TR LEVEL) 6 YES I
CPU YES for DR780 self-test diagnostics (A, B, C, D, and F) only. Check the individual
diagnostic listing for a complete list of attachments needed to operate the diagnostic.

Select the unit to be tested via the command SELECT and UNIT # (i.e., SELECT XF AO:).

Set any desired supervisor flags.

START the program.

When running diagnostics for the first time after an installation of the DR 780, run in ascending order
from ESDFA to ESDFG.

6-9

6.7 LOADING THE DR780 MICROCODE
Use the following procedure to load the DR780 microcode from the diskette.
NOTE
The microcode must be loaded into the DR780 each
time the DR780 is power enabled.
1.

Once the system is available for use under the system manager, type:
$SET DEFAULT [SYSUPD]

Load the DR 780 microcode diskette in the disk unit, type:
$ @VMSUPDATE

Answer the question asked by the system.

Remove the diskette from the disk unit, type:
$ RUN SYS$SYSTEM:XFLOADER

This loads the DR780 microcode into the WCS RAM of the DR780.
It is recommended that the above command be put into the system startup file.

6.8 USING UETP TO TEST DR780
The following must be done in order to use the User Environment Test Package (UETP).
1.

The DDI cable must be disconnected from the DR780 to be tested. If this cable is BC06V-*,
it is located at the bottom of the back of the cabinet that holds the DR780. If this cable is
BC06B-R, the paddle card should be removed from the backplane of the DR780.

The file XF780.ULD (DR780 microcode file) must exist in SYS$SYSTEM:. It must be copied to the system disk from the diagnostic media.

With the DR780 power removed the following backplane jumper changes must be made.
a.

The MA 780C connects the SBI to the MA 780A/B. It has a 3 1/4-inch backplane which goes in the CPU or SBI expander cabinet, cables, and M9045
paddle cards. The MA 780C backplane is connected to the SBI. The M9045
paddle cards plug into the MA 780A/B and MA 780C backplanes. The bidirectional data interconnect cables (BDI) connect the M9045s on the MA 780A/B
to the M9045s on the MA780C. The MA780C can be ordered alone only with the purchase of a configured system (MA 780E).

MA780D

The MA 780D is the MA 780A/B Multi port Memory Selective Cache Invalidate option. It is a single M8210 memory array board which is plugged into
slot 9 in the MA 780A/B backplane. It requires no further action.

MA 780EA 60Hz
MA780EB 50Hz

The MA780E consists of an MA780C and an H7100 Power Supply. This option
is the only way MA 780C add-ons can be ordered.

MA780F

The M,A.,. 780F has a H9604 left expander kit, an H9504-XE joiner kit, and two
plenum weld panels. One MA780F is needed to change a two VAX-11/780 system configuration to a three VAX-11 /780 system configuration. Another
MA 780F is then needed to change a three VAX-11 /780 system configuration to
a four VAX-11 /780 system configuration.

9-1

9.1 MA780 SYSTEM CONFIGURATIONS
The MA 780 can be configured with two to four VAX-11 /780 systems. With two systems the cabinets
are arranged in a straight line. The three-system configuration is a "T", and the four-system configuraton uses a "pi" arrangement.
NOTE
The procedures used in this chapter assume that the
VAX-11/780 systems to be worked on have been
properly halted and powered-down. The main circuit
breakers on the power controllers of all systems are
set to OFF and all ac connections to the systems
have been removed.
9.1.1 Two-System MA 780A Configuration
A two-system configuration consists of one MA 780, two VAX-11 /780 CPUs, and an H9604 left expander kit. Figure 9-1 shows that the main CPU /SBI expander cabinet units are adjacent to the MA 780
cabinet. One of the two systems to be joined must be arranged to match the configuration shown in
Figure 9-1. Engineering drawing H9604-AA can be used as a reference during this assembly process.

9.2 THE MA780C PORT INTERFACE ASSEMBLY
The MA 780C port interface assembly is the port interconnect between the MA 780A/B and the synchronous backplane interconnect (SBI) of the VAX-11 /780 system. The MA 780C can be installed on
the SBI in several ways.
•

The MA780C can be installed in the 3 1/4-inch slot which usually has the SFT (M9043).
The SFT is removed and the MA 780 installed. The MA 780C can then use slot 3 for a port,
and slot 2 for the M9040 board, which is an SBI terminator. If both slots 3 and 2 in the
MA 780C are used for ports, then the SBI is continued into the SBI expander cabinet where
the SFT is installed to terminate the SBI.

•

The MA 780C can be installed in the SBI expander cabinet if space is not available in the
CPU cabinet. Whether one or two ports are used, the M9043 SFT is always used to terminate
the SBI in the SBI expander cabinet.

•

If two MA 780Cs are installed on one SBI, one is usally in the CPU cabinet, the other in the

SBI expander cabinet. Both can be in the SBI expander cabinet if desired. They should be
adjacent to each other on the SBI due to the relatively short ( 15-inch) mark interlock cable.
The following paragraphs describe the installation of the MA 780C interface assembly including power
cabling and jumper configurations. Connecting the BDI and power cables from the MA 780C to the
MA 780A/B is described in paragraph 9.3.2.1.
CAUTION
The MA780C usually uses the MS780 +5 Volts.
The MS780 uses an unswitched ac power source.
Thus when the CPU cabinet is shut down using the
key, the MS780 and the MA 780C still have + 5
Volts applied to them.
9.2.1 Installation
The following paragraph describes the installation of the MA 780C interface assembly in the main CPU
cabinet and/or the SBI expander cabinet.
NOTE
If installation includes two MA 780C backplanes on
one SBI, they should be adjacent on the SBI due to
the short (15-inch) interlock cable provided.
All systems should be powered off at this time.
1.

Remove the M9043 SBI terminator assembly from the system as directed in paragraph 9.9.

9.2.2 MA 780C Power Cable Installation
MA780C power connections may change depending on the number of ports connected to one SBI. The
following paragraphs show the connections for a single port and for two ports on the SBI. The differences that occur when the MA 780C is installed in the SBI expander cabinet are noted.
CAUTION
J15 on MA 780C (mark interlock) should only be
connected to J15 of another MA 780C.
9.2.2.1 One SBI Port - Installation of the MA780C power cables (P/N 7016885-00 and 7016884-00)
is done from the back of the MA 780C assembly (Figures 9-20 and 9-22).
1.

Make the following connection using the power cable unit (P /N 7016885-00).
a.

Connect Pl to JI 6 of the MA 780C backplane.

Remove P3 (-5.2 volts and groµnd) from the_ previoµs option b~ckplane. Connect P3 to
J7. Connect J 6 to the option backplane where P3 was.

Connect the red wire with a lug attached, to the + 5 volt side of the MS780 power supply. Connect the black wire with a lug attached, to the ground side of the MS780 power
supply.

Connect plug J4 to 120 of the MS780 backplane.

Connect J3 to J3 of the MS power supply.

Plug J 5 is installed in the MA 780 cabinet. The wires attached to J 5 run along the BO I
cable to the MA 780. Installation of the BDI cable and the connection of JS are described in paragraph 9.3.2.1, step 4.

If the SBI is terminated by the M90043 SFT in the SBI cabinet, the cable (P /N 7016884-0)
is excess material. If the SBI is terminated at the MA 780C backplane by the M9040, then
make the following connections using the power cable unit (P /N 7016884-0) .

When the SFT was removed three connectors were left unconnected.

JI, 12 and J3 plug into connectors JI, 12 and J3 respectively of the SFT cable.

The mark interlock cable is excess material (it is only used if there are two MA 780C backplanes on one SPI).

9.2.2.2 Two SBI Ports - Installation of the MA 780C power cable using the two ports on the MA 780C
is similar to the installation using one port (Figures 9-21 and 9-22).
1.

Install cable (P /N 7016885-00); refer to paragraph 9.2.2.1.

Install cable (P/N 7016885-00, identical cable) at JI4 of the MA780C.

The SBI cannot terminate at an MA 780C which uses both ports; it must go on to the M9043
SFT or to the next SBI device.

The excess material includes:
•
•
•

I MA780C backplane
2 cables (P /N 7016884-00)

The SBI is terminated by either the M9043 SFT or by the M9040, not both.

The SBI terminator in the SBI expander cabinet is always the M9043 SFT.

The M9040 SBI terminator uses slot 2 of the MA 780C backplane, which is the same slot
used by the second port in the MA 7 80C. If both ports in the MA 7 80C are to be used, then
the SBI cannot be terminated in that MA 780C.

The M9043 SFT location in the CPU cabinet is on a 3 1/4-inch blank. The M9043 SFT
locations in the SBI expander cabinet are 4-inch blanks.

9.9.1 Replacing M9043 SFT With M9040 in MA 780C
Use the following procedure to replace the M9043 SFT with the M9040 in the MA 780C backplane.
1.

Halt and power down the connected VAX-11 /780 systems. Set the main circuit breaker on
the power controllers of all systems to OFF and remove all ac connections to the systems.

From the back of the cabinet:
a.

Remove and save the six long SBI jumper cables (P /N 1700087-01) connected from the
SBI terminator to the adjacent backplane.

Disconnect plugs P7, P8 and P9 from the lower portion of the SBI terminator.

Remove and save the two screws that hold the 3 1/4-inch blank (with SBI terminator)
to the top of the card cage.

From the front of the cabinet remove and save the four screws that hold the 3 I/ 4-inch blank
(with SBI terminator) to the bottom of the card cage.

Remove the 3 1/4-inch blank (with SBI terminator) from the card cage by sliding the assembly out from the back of the cabinet.

Carefully pack the M9043 SFT terminator and 3 I/ 4-inch blank with the screws saved in
step 3. These parts will be needed if an SBI expander cabinet is ordered for this CPU at a
later date.

After the MA 780C backplane has been installed in the CPU cabinet, install the six long SBI
jumper cables saved in step 2.a.

9-49

9.9.2 Moving M9043 SFT from CPU to SBI Expander Cabinet
Use the following procedure to move the M9043 SFT from the CPU cabinet to the SBI expander cabinet.
1.

Halt and power down the connected VAX-11 /780 systems. Set the main circuit breaker on
the power controllers of all systems to OFF and remove all ac connections to the systems.

From the back of the cabinet:

Remove and save the six SBI long jumper cables (P /N 1700087-01) connected from the
SBI terminator to the adjacent backplane.

Disconnect plugs P7, P8 and P9 from the lower portion of the SBI terminator.

Remove and save the ten screws which hold the M9043 SFT to the 3 I/ 4-inch blank.

Install the M9043 SFT on the 4-inch logic blank (either 1, 4 or 6) in the SBI expander
cabinet. Use the ten screws removed in step c.

Remove the 3 1/4-inch blank from the CPU cabinet.
a.

From the back remove and save the two screws that hold the 3 1/4-inch blank to the top
of the card cage.

From the front remove and save the four screws that hold the 3 I/ 4-inch blank to the
bottom of the card cage.

Remove the 3 1/4-inch blank from the card cage by sliding the assembly out from the
back of the cabinet.

The screws removed in steps a and b can be used to fasten the MA 780C backplane in
this 3 1/4-inch space. The 3 I/ 4-inch blank is excess material.

After the other options have been installed in the CPU cabinet and SBI expander cabinet, do
the following from the back of the SBI expander cabinet.
a.

Install the six long SBI jumper cables (P/N 1700087-01) from the last SBI option to the
M9043 SFT.

Connect P7 to J7 and P2 to J8. In the SBI expander cabinet J9 is not used.

9.10 MA780 DIAGNOSTICS
There are three types of diagnostics for the MA 780: microdiagnostics, macrodiagnostics, and UETP.
Microdiagnostics should be run first. After running microdiagnostics with no failures, run macrodiagnostics. Finally, after passing both microdiagnostics and macrodiagnostics with no failures, run UETP.

9-50

9.10.1 MA 780 Microdiagnostics
The microdiagnostics for the MA 780 are on RX #22 of the VAX-11 /780 microdiagnostic diskette set.
RX #22 contains ESKAN which has sections 3E to 65 of the VAX-11 /780 microdiagnostics; these
sections test the MA 780. For detailed procedures on running these microdiagnostics refer to section 4.6
of the ESKAA file (on microfiche). Sections 3E to 62 are divided into three groups and are run using
the procedures for the previous VAX-11 /780 microdiagnostics.
Section 63, the powerfail test, requires manual intervention by the person running the microdiagnostics.
Sections 64 and 65, the CPU to CPU interaction test, requires an RX #22 at each CPU.
9.10.2 Macrodiagnostics (ESCCB)
The program ESCCB is a level 3 standalone diagnostic exerciser run under control of the diagnostic
supervisor (ESSAA). ESCCB is on diskette RX #57 and ESSAA is on RX #8. The program is designed
to exercise two to four VAX-11/780 CPUs connected to one or two MA780 multiport memories. The
detailed- i-nf-orma-tien needed-t-0---run t-his exerciser is in the ESCCBJistings__(onmicrofic_he).

Connect the ground cable between the first RK07 and the CPU cabinet.

If the remote diagnostic option is used, cable it to the CPU cabinet via dedicated connector
J3 on the 1/0 panel assembly in the KC780.

If additional UNIBUS-option peripherals are to be installed, each peripheral must be connected to the CPU cabinet via an H7004B, 40-pin filtered connector that must be installed in
one of the six connector slots (J4 through J9) on the 1/0 panel.

After cabling any peripherals present, enter their 1/0 location (J4 through J9) on the allocation sticker provided on the right front upright of the cabinet, so that each peripheral connection at the 1/0 panel is clearly identified.

If the peripheral was ordered as an add on, not with the original UNIBUS VAX-11/780, the
peripheral interface interconnect for that device is connected to the 1/0 panel half of the
1/0 panel connector via a BCU6K mirtor-image eable: The H7004B--40-pinfilter and one
BC06K-9K cable needed to complete the installation of the peripheral are supplied with the
