Load DR780 diskette number 1 into the diskette disk drive.

Type “B0” on the console terminal.

6-7

Wait for DS) prompt.

Type the following command lines:

“Attach DR780 SBI XFAO [TR#] [BR#] YES | CPU YES”
“SELECT XFAO”

“Load ESDF?” where 7=A, B, C, D or F.
“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 DR780
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 DR780 Control Board (DCB) and DR 780 microprocessor board (DUP).

ESDFC -

This is a standalone diagnostic package that uses its own microcode to test all func-

tions used by the DR780 silo module (DSM), and the out of sequence logic on the
DR780, located on the DSC and DCB.

ESDFD -

This program exercises the DR780 with the standard DR780 microcode. It is a standalone diagnostic package that checks the correct functioning of the DR780 by per-

forming actual data transfers with different block sizes, and in different error and
nonerror modes. The exercising of the DR780 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 func-

tion 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 DR780 in user mode.

ESDFG -

This package is similar to ESDFE, but it tests the DR780 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 E0O4M1 to EO4R1 of the DR780 backplane
Jumper EOEM2 to EOER?2 of the DR780 backplane

Configure jumpers W1 through W4 for the correct TR level (refer to Engineering Drawing
E-UA-DR780-0-0, 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 DR780 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:FEO00 (from the diskette) or RUN ESSAA (for user mode diagnostic).
Load the diagnostic program by its designation letters, i.e., LOAD ESDFA (ESDFA is the
program ID).

Attach the device to be tested; ATTACH DR780 SBI (UNIT #) (TR LEVEL) 6 YES 1
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 XFAO:).
7.

Set any desired supervisor flags.

START the program.

When running diagnostics for the first time after an installation of the DR780, 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.

Once the system is available for use under the system manager, type:

$ SET DEFAULT [SYSUPD]
Load the DR780 microcode diskette in the disk unit, type:

§ @VMSUPDATE
Answer the question asked by the system.
Remove the diskette from the disk unit, type:

$ RUN SYSSSYSTEM: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).
The DDI cable must be disconnected from the DR780 to be tested. If this cable is BCO6V-*,

it is located at the bottom of the back of the cabinet that holds the DR780. If this cable is
BCO06B-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.
Ao o

Remove the jumpers from W7 and W8 (at the top of the backplane).
Add the jumpers from E04M1 to EO4R1.
Add the jumpers from E04M2 to E04R2.
Refer to UETP User’s Guide (AA-D643A-TE) for startup of the UETP.

CHAPTER 9

MA780 MULTIPORT MEMORY

The MA780 Multiport Memory is not one simple option but is a series of MA780 options ranging from
A to F. A general description of the hardware follows.

MA780AA 60HZ
MA780AB 50Hz

The MA780A is a VAX-11/780 Multiport Memory in a modified highboy
(H9602) corporate cabinet with a Memory Power Supply, an 869 power controller, two MA780C interconnect units and an optional H7112 battery backup
unit. The MA780A comes with 256 kilobytes of memory which is expandable to
a maximum of 2 megabytes.

MAT780BA 60Hz
MA780BB 50Hz

The MA780 is a VAX-11/780 Multiport Memory with a memory power supply,
two MA780C interconnect units, and an optional H7112 battery backup unit.
The MA780B also comes with 256 kilobytes of memory which is expandable to
a maximum of 2 megabytes. The MA780B is installed in the MA780A cabinet.
The cabinet holds two multiport memories.

MA780C

The MA780C connects the SBI to the MA780A/B. It has a 3 1/4-inch back-

plane which goes in the CPU or SBI expander cabinet, cables, and M9045

paddle cards. The MA780C backplane is connected to the SBI. The M9045
paddle cards plug into the MA780A /B and MA780C backplanes. The bidirec-

tional data interconnect cables (BDI) connect the M9045s on the MA780A /B
to the M9045s on the MA780C. The MA780C can be ordered alone only with
the purchase of a configured system (MA780E).

MA780D

MA780EA 60Hz
MA780EB 50Hz
MAT780F

The MA780D is the MA780A/B Multiport Memory Selective Cache In-.
validate option. It is a single M8210 memory array board which is plugged into
slot 9 in the MA780A /B backplane. It requires no further action.

The MA78OE.consists of an MA780C and an H7100 Power Supply. This option
is the only way MA780C add-ons can be ordered.

The MA780F 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
MA780F is then needed to change a three VAX-11/780 system configuration to
a four VAX-11/780 system configuration.

9-1

9.1
MAT780 SYSTEM CONFIGURATIONS
The MA780 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 MA780A Configuration
A two-system configuration consists of one MA780, two VAX-11 /780 CPUs, and an H9604 left expan-

der kit. Figure 9-1 shows that the main CPU/SBI expander cabinet units are adjacent to the
MA780
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.

THE MA780C PORT INTERFACE ASSEMBLY

The MA780C port interface assembly is the port interconnect between the MA780A /B and the synchronous backplane interconnect (SBI) of the VAX-11/780 system. The MA780C 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 MA780 installed. The MA780C 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
MA780C are used for ports, then the SBI is continued into the SBI expander cabinet where
the SFT is installed to terminate the SBI.

The MA780C 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 MA780Cs 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 MA780C interface assembly including power
cabling and jumper configurations. Connecting the BDI and power cables from the MA780C to the
MA780A/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 MA780C still have +5
Volts applied to them.
9.2.1

Installation

The following paragraph describes the installation of the MA780C interface assembly in the main CPU
cabinet and/or the SBI expander cabinet.

NOTE

If installation includes two MA780C 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.

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

Install the MA780C port interface backplane assembly in the location where the SBI termi-

nator assembly was.

a.
b.
c.

From the back of the system, slide the MA780C backplane assembly into the slot made

available by the removal of the SBI terminator.

Fasten the MA780C assembly to the back of the card cage, at the top of the unit, with

the two screws and star washers supplied.

Fasten the front of the MA780C assembly to the card cage, at the bottom of the unit, by

installing the two screws and star washers supplied.
9-19

Install the M8258 (MPI) board(s) (Figure 9-18) into:

Slot 3 for a one-port installation

Slot 3 and 2 for a two-port installation

Install two blank modules (P/N 7014103) into slots 1 and 4 of the MA780C.
Install the SBI terminator (M9040 or M9043) as directed in paragraph 9.9.

Install the M9045 paddle cards and the BDI cables in J1 and J4; refer to paragraph 9.3.2.1
and Figure 9-19.

MA780C Power Cable Installation

9.2.2

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 MA780C is installed in the SBI expander cabinet are noted.
CAUTION
J15 on MA780C (mark interlock) should only be
connected to J15 of another MA780C.

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 MA780C assembly (Figures 9-20 and 9-22).
1.

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

b.
c.

Connect P1 to J16 of the MA780C backplane.

Remove P3 (—5.2 volts and ground) from the previous option backplane. Connect P3 to

J7. Connect J6 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 J20 of the MS780 backplane.

Connect J3 to J3 of the MS power supply.

Plug JS is installed in the MA780 cabinet. The wires attached to J5 run along the BDI
cable to the MA780. Installation of the BDI cable and the connection of J5 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 MA780C backplane by the M9040, then
make the following connections using the power cable unit (P/N 7016884-0).
a.

When the SFT was removed three connectors were left unconnected.

J1, J2 and J3 plug into connectors J1, J2 and J3 respectively of the SFT cable.

The mark interlock cable is excess material (it is only used if there are two MA780C backplanes on one SPI).

9.2.2.2 Two SBI Ports — Installation of the MA780C power cable using the two ports on the MA780C
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 J14 of the MA780C.

The SBI cannot terminate at an MA780C which uses both ports; it must go on to the M9043
SFT or to the next SBI device.

The excess material includes:
e

1 MA780C backplane

2 cables (P/N 7016884-00)

2 mark interlock cables

Install the BDI cable (P/N 7016886-14) from the MA780Cs, located in the main CPU or

SBI expander cabinets, to the MA780A /B backplane.

Plug connectors J1 through J4 of the BDI cable into the corresponding MA780C
M9045 paddle card connectors J1 through J4. The red edge of the cable should point up
and connect to pin 1 of the paddle card connectors.

Route the BDI cable to the MA780 cabinet, through the MA780 cable trough to the
MA780A /B backplane. Use the cable connection diagram for the configuration being
installed. (The BDI cable loops back in the same direction it came from. This enables
the slack to be taken up in the lower cable trough.)

Plug connectors J1 through J4 of the BDI cable into the corresponding MA780A/B
M9045 paddle card connectors J1 through J4. The red edge of the cable should point up
and connect to pin 1 of the paddle card connectors.

Connect the —5.2 volt and ground supplied by the MA780C to the MA780A/B receiving
slot. This power is carried from either J16 or J14 on the MA780C via J5 of the MA780C
wiring harness to one of J9, J8, J7, or J6 on the MA780A/B backplane. The wiring attached
to J5 follows the route of the corresponding BDI cable. Refer to BDI cable figures for connections.

a.

For a three-port installation, connect the three power

harness cables (P/N 7016885-00)

(Figure 9-33). Cable (P/N 7016884-00) is inserted in J14

of the second MA780C if the
SBI is terminated with the M9040 in the MA780C. If the
SBI continues on to the expander cabinet, J14 has no connections and cable (P/N
7016884-00) is not used (Figure
9-35 contains the notes and tables for Figure 9-33).

For a four-port installation, connect the four power
harness cables (Figure 9-34). The
SBI continues on to the SBI expander cabinet and is
terminated there (Figure 9-35 con-

tains the notes and tables for Figure 9-34),

SBI TERMINATOR ASSEMBLY

The following paragraphs describe the removal and installation of the SBI terminator assembly for the
VAX-11/780 system.
1.

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 MA780C backplan“e':,”\;;/-hi(-:.h is the same slot

used by the second port in the MA780C. If both ports in the MA780C are to be used, then
the SBI cannot be terminated in that MA780C.

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.

Replacing M9043 SFT With M9040 in MA780C

9.9.1

Use the following procedure to replace the M9043 SFT with the M9040 in the MA780C backplane.

MA780 DIAGNOSTICS
There are three types of diagnostics for the MA780: microdiagnostics, macrodiagn
ostics, 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

MA780 Microdiagnostics

9.10.1

The microdiagnostics for the MA780 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 MA780. 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 information needed to-run this exerciser is in the ESCCB.listings (on microfiche).
