This Maintenance Guide gives notes about the core
approach in Sections 1 to 9, with details of options that
are, or may be found in a MKIV Controller, in appendices.

NOTE
When a Controller has to be changed on-site,
the Engineer must remove any options from
the defective unit, and return them to stores as
individual options. This must be done separately
from the return of the basic Controller, to
satisfy the administration procedures.

MAINTENANCE GUIDE (MKIV)
Details of specific configurations can also be found in

appendices.

MAINTENANCE GUIDE (MKIV)

The World Box enclosure houses the power supply and

backplane assembly and has space for five mass storage
devices. The Box is covered by removable panels, on the
right and left sides and the front. These are held onto the

main framework by push catches. See Figures 2-3 and 2-4
for the location of these catches.

There are three doors in the box. One at the front, for
access to the Control Panel, one at the back for access to
the I/O Panel, and a card cage door inside the right side
panel.
THE CONTROL PANEL
The control panel of the World Box is located at the
bottom left of the front panel behind a small access door.
Figure 2-7 shows the layout of this panel.

THE CPU CONSOLE BOARD

Figure 2-8 shows the

CPU Console Board.

The RESTART switch is a momentary action push

switch. Pushing this switch will BOOT the system,
depending upon the position of the maintenance switch
(see Section 3) . The LED in this switch is ON when the
CPU is running.
The DCOK (green) LED is ON when the system is
receiving stable voltages from the power supply.

Regulator A and B LEDs indicate which of the two
/ regulators have failed if the DCOK indicator is OFF.
NOTE
There should be at least ONE module in both
the ODD and EVEN-numbered slots of the
backplane to draw enough current to start the

regulators.

Make sure that both DIP switches on the Console board
are OFF.

Air Flow

A PCB mounted above the card cage regulates the flow
of air by sensing the temperature in the box. One circuit
increases the speed of the card cage fan when the
temperature rises above a minimum level, the other shuts

down the system when a high operating temperature is

reached. The system also shuts down if the card cage fan
stops.

The Removable Panels of the World Box

Removing the Side Panels
Refer to Figures 2-3 and 2-4 as appropriate.
1.

Open the front door (left panel), or the rear door
(right panel).

Using a medium sized slot screwdriver or a coin

remove the side panel locking screw.

Keep the screw in a safe place.

Using the tips of the fingers placed near the side

panel push-catches, pull the bottom edge of the

panel outwards until it comes free from the
framework.

MAINTENANCE GUIDE (MKIV)

Lift the panel so that the top edge comes free
from the framework.

Store the panel in a safe place.

2. Removing the Front Panel
CAUTION

Trying to remove the front panel BEFORE
removing the side panels can cause the tabs on

the front panel to break.

When both side panels have been removed:

With the fingertips positioned near each of the
bottom push fit catches, pull the panel outwards

until it is free of the framework.

Repeat the above process for the upper push fit
catches.

The panel is now free of the framework and can
be stored in a safe place.

Replacing the Side and Front Panels
Replacement of the panels of the World Box is a simple

reversal of the above procedures.

e
e

Replace the front panel first.
At all times apply closing pressure directly over
the push fit catches.

}

Removing the Card Cage Door
NOTE

When this door is removed the air flow
around the modules is reduced. A switch has
been incorporated to detect the absence of the

door and to increase the speed of the cooling

fan to maintain the cooling level.
1.

Remove the right hand side panel.

Locate the card cage door snap catches, undo
them and open the door.

MAINTENANCE GUIDE (MKIV)

Lift the door away from the framework by gently
working the bent metal tabs free from their
retaining slots. The door is located by means of a

ninety degree ‘joggle’, pressed into the entire

length of the door. The joggle is in turn located in
a slot in the frame and this arrangement acts as
the hinge. It is important therefore that removal
is done by manipulating the door rather than
forcing it.

4.
5.

Store the door in a safe place.

Replacing the Card Cage Door
Reverse the above process, taking care not to snag any

cables.

Replacement of Fans
NOTE
the power supply
1.

Isolate the power.

Gain access to the fan by remavmg the appropriate side panel.

Disconnect the fan supply voltage connector.

Unscrew the fan retaining screws, and remove
the fan.

Position the new fan and screw it firmly into
place.

Connect the fan supply voltage connector.

Replace the panel(s).

Restore the power.

TESTING - THE USE OF THE DIAGNOSTICS
NOTE

The MKIV diagnostics are NOT usable on the
MKIII series Controllers.

INDICATORS

The indicators are used by the system to show when
various activities are being performed by the CPU. The
LEDs also include indicators to show when the CSS
Diagnostics are being run and the completion of a pass.

If the CSS diagnostics LED is lit the codes are |

generated by the CSS diagnostic software (see Table 3.2).
If the CSS diagnostics LED is not lit the codes are
generated by the normal software.

Figure 3-1 shows the layout of the LEDs.

KDJ11-B PROM:s

There are three diagnostic PROMS on the KDJ11-B:
e

Diagnostic PROMS (High and Low Byte)
These contain the standard Corporate tests for
the CPU and memory. They produce LED
codes 00 to 77, without any leading or trailing
points. There is NO engineering access to these
PROMS.

MAINTENANCE GUIDE (MKIV)

Configuration EEPROM
This holds information used by the Corporate
PROMS and the configuration table used by the
MKIV Diagnostic System.

The device table in the EEPROM can be
accessed to control the testing sequence or to
change the options in the test routine.

To make changes to this table, connect an LA12
console to the Console Connector on the
KDJ11-B.

! THE BASIC DIAGNOSTIC ROUTINE

When powering ON or performing a RESTART the
Corporate PROM will test the CPU and memory. If OK,
and the MAINT switch is not ON, the Barclays system
will be booted from RD5 3 drive 0. Ifthe MAINT switchis

ON, it will attempt to boot the Diagnostic System from
TK50 drive 0, RX50 drive O or 1 in that order. If none of
these is available the CPU will enter an internal loop.

The flowchart in Figure 3-2 shows the general scheme

of the diagnostics.

MAINTENANCE GUIDE (MKIV)

Installation

Control of the EEPROM Configuration table will be
needed when a new EEPROM is installed or when a new

option is added to the system.

The following notes show the method used to modify

the EEPROM contents.

A Configuration Table Facility is included in the
Diagnostic System. If both MAINT and ENG TEST
switches are ON, the Facility will be invoked by two
conditions:

If the EEPROM validation check in the CSS
Diagnostic System routine produces an error.

NOTE

If the EEPROM Validation Check finds a
fault when the ENG TEST switch is OFF the
CPU is halted. Code 6, ‘Invalid EEPROM
contents detected’, is displayed.

If a character input is detected when an LA12
console is connected to the KDJ11-B, the
message ‘Break request, Y/N’ will be displayed.
Type ‘YES’.

These cgnditians will cause the prompt,
‘EEPROM Configuration Facility’
to be printed, followed by a list of the allowable responses,
and the Facility prompt,
‘COM>’

Type in the command needed and answer the Facility
messages.

When using this routine to alter a Configuration Table
entry the complete set of fields within the entry must be
examined and terminated with <RETURNZ> to write the
new data into the EEPROM.

MAINTENANCE GUIDE (MKIV)

User input can be deleted by:
1.

Delete key.

The Facility will echo the deleted characters in
upper case and enclosed in backslashes.
Control U

Deletes the complete input line. ‘Repeat input>’
will be displayed.

Control Z will abort an entry amendment. The EEPROM
contents will not be changed.

There are two types of loopback connector for KMV11
ports, EP-E155A-00 for RS-422 lines, and EP-156 A-00

for RS-423/232-C lines. (Run the test for two passes with

each type of connector in each KMV11 port. That is to say,
two times two passes of VKME.)

SECTION §
BACKPLANE UTILIZATION
The backplane used in the MKIV Controller is a
standard BA123 backplane.

The slots are numbered 1 to 12 from right to left when
viewing the card cage from the right hand side of the
controller.

The CPU module must be located in slot 1 with the
memory next to it in slot 2.

Figure 5-1 shows the serpentine bus layout. The
maximum system configuration is shown. You should
refer to this diagram to decide upon the configuration
required.

SECTION 7

THE 30-23616-01 POWER SUPPLY
~

INTRODUCTION

The 30-23616-01 is a double, Switched Mode Power
Supply, contained in a box mounted on the left hand side

of the World Box.

When the DC voltages are all correct the DCOK LED

will be ON.

The low voltages drive the logic, the LEDs and the two
cooling fans (which cool the card cage and the storage
drives respectively).

Each regulator unit in the 30-23616-01 provides the
same voltages to the card cage backplane. The distribution
of these voltages is to alternate slots, that is 1,3,5,7 and so
on from regulator A, and 2,4,6,8 and so on from regulator
B.

CAUTION

Outputs A and B must not be mixed in use

between the PSU’s.
NOTE

These regulators need a minimum load to
function correctly. A current drain of LESS
THAN 4.5A @ 5V from either regulator will
cause it to shut off and give a fault indication.

Figure 7-1 shows the physical location of the 30-

23616-01.

SECTION 8
BARCLAYS FAULT REPORTING PROCEDURE
When Barclays staff experience operational problems
or suspect a fault on the Back Office Controller Network
their actions are:

Reporttothe LOCALNETWORK CONTROL

At: WYTHENSHAWE
GLOUCESTER
GREATER LONDON

Local Network Control will investigate possible Net-

work problems, these will be cured, or, if none exist at this
level:

Barclays Branch will contact MANAGEMENT
SERVICES FAULT CONTROL DESK
At: RADBROKE HALL, KNUTSFORD

Control desk staff will then check the fault indication
status on the Controller Display Panel. The display will

indicate one of three major failing areas:

The NETWORK
The BACK OFFICE TERMINALS
The CONTROLLER
Network
If it is still felt that there may be a Network problem, the
Network will be re-checked by both the Control Desk and
the Control Centre. They will look for possible failures in
the following areas:
The CONTROL CENTRE
The BRITISH TELECOM LINE
The DCU MODEM
Back Office Terminals
If the Back Office Terminals are shown to be faulty, the
Control Desk will perform further tests to find the type of
fault. This will then be reported to either BURROUGHS
or OLIVETTI as appropriate.

MAINTENANCE GUIDE (MKIV)

Controller
If the fault is thought to be in the Controller itself,
Barclays Staff will be required to:
1.

Record the fault

Load the TKS50 based diagnostics

Initialize the Controller (by pressing the INIT
button at the back of the Controller)

This will start the Internal Self-Test sequence. (For Mk I,
II and III Controllers the diagnostics are PROM based
internally requiring no further action from the Barclays
Branch staff other than pressing the INIT button after
recording the fault).

The diagnostics will stop runfiing when they detect a

fault, and this will be indicated on the front panel display.
4.

When the failure has been diagnosed, the Barclays

Branch staff will report their findings to
BARCLAYS SUPPORT SERVICES, who
will in turn log the fault with DIGITAL.
FAULT HANDLING PROCEDURES
On receipt of a fault call:

DIGITAL FIELD SERVICE must contact the Barclays
Branch who have reported the fault:
1.

To give Barclays Branch the expected time of

arrival of the Engineer on site.

To inform Barclays Branch if an Option Swap
and Hardware Support Kit will be arriving on
site separately (by taxi or by local Logistics
van).

Arrival on site:
When the Engineer arrives on site confirmation of
arrival must be made by telephoning the BARCLAYS
CONTROL DESK (Tel 0565 50381). The details of the
fault call must also be checked.

MAINTENANCE GUIDE (MKIV)

On completion of the call:

When the Engineer has finished the fault call, the
BARCLAYS CONTROL DESK must be contacted. A
report of the fault found, and subsequent actions taken
must be given.

The call should then be logged off with the Engineer’s
own Field Service Branch office.
NOTE

At all times during a fault situation, BARCLAYS
MANAGEMENT SERVICES Control Desk
should be kept aware of the situation on site,
and of any problems encountered. THEY
CAN BE OF GREATHELPIFTHEY ARE
INVOLVED.

FAULT CODES
See Table 3-1

OPERATION
This device has no external operating procedures.
TESTING
See Section 4 for details of the Diagnostic System.
The KMV11-B is tested by the CSS written, Barclays
Controller Diagnostic System. This is loaded from either
the RXS50 or the TK50 and runs automatically when the

) MAINT. switch is ON. The ENG. TEST switch OFF
will test the KMV11-B internally, that is, excluding the
line drivers and cables.
When the ENG.TEST switch is ON, the KMV11-Bis
tested externally and the diagnostic expects the loopback
connectors to be in place. This mode will test the lines and
drivers on each channel in either RS423, or, RS422, but
not both. To fully test all lines and drivers swap the
loopback connectors over and repeat the external test.
When a console is fitted, there is a quicker way to run the
second pass tests, as follows:
Press ANY key to halt the diagnostics

You will get ‘BREAK REQUEST 7

Type ‘Y’

You will then get the prompt ‘COM>’

Change the loopback connectors
Type ‘R® <RETURNX>> and the test will now run.

A failure will cause a fault code to be displayed in the 7
segment LED indicators.
