BARCLAYS BRANCH

CONTROLLER MKIII
MAINTENANCE GUIDE

INTRODUCTION
An internal diagnosticin the Barclays branch controller
tests the controller modules at power-up or initialization.
The diagnostic checks the position of the keyswitch on the
front panel, and modifies the test sequence as follows:

NORMAL
The diagnostic runs one complete pass of the test

sequence and then boots from the system disk. External
loopback tests are not performed, so the loopback con-

nectors are not used. Front panel toggle-switches are

/ disabled.

TEST
'External 1aa§ba¢k tests ARE perfi ;rmed, sO Ieagback

connectors must be installed on all communications
connectors. The diagnostic will cycle mfinueusiy Boot
will NOT occur until the keyswitch is moved from the
TEST position. Front panel toggle-switches are enabled.

AUX
This keyswitch position is used to select a fast boot.
Only basic CPU functions, the DRV11, and the first 32K
words of each memory board are tested. This limited test
takes about one minute. The disk drives are then tried in
the order below. The system is booted from the first drive

which has bootable media loaded.

RX50 0 (logical drive 1)

RXS50 1 (logical drive 2)

RDS52 (logical drive 0)

Front panel toggle-switches are disabled.

MAINTENANCE GUIDE (MKIlI)

‘TESTING THE SYSTEM
CAUTION
At all times, remove any RXS50 diskettes
before switehing the power ON or QFF

Check that the mains power switchis QN The switchis
located at the back of the controller, and can be accessed
from the right-hand side. Before starting the diagnostic,
check that the PWR OK and AUX PWR OK LEDs on
the front panel are ON, and that the fans are running. If
either LEDs or fans are not working, refer to Section 2. If
allis working correctly you can continue.
Make sure that the HALT switch is up and the
keyswitch is in the NORMAL position. Then press the
initialization (INT) button. This button is just above the
mains ON/OFF switch.

Check that the six diagnostic LEDs are flashing the
alternating pattern shown in Table 1 (LED Test). This
proves that all the LEDs are working. The test lasts about
10 seconds and indicates that the diagnosticis running.
After this the LEDs flash the mark and firmware revision
code for five seconds (see Appendix F). The RUN LED
should be on. The diagnostic tests each field-replaceable
unit (FRU) in turn,
displays a code on the six LEDs
that indicates the FRU under test. If an FRU has failed,.
the RUN LED goes off, leaving the FRU code displayed
on the six LEDs.

See Table 1 for display codes, to find out which FRU

has failed and where removal/replacement is described.

A successful test (RUN LED on, six LEDs off) should
take about 10 minutes. If the diagnostics are successful,
move the keyswitch to the TEST position, fit loopback
connectors on the distribution panel (see Figure 1 for
loopback layout), and insert two scratch diskettes in the
RX50. Press the initialization button and run the test for
one complete pass. Swap the KMV11 loopback connectors
and then repeat the test. Thus each KMV11 connector is
tested with both types of loopback.

If the diagnostics run one error-free pass with each
loopback, the unit should be serviceable. If there is an
error, replace the indicated FRU and test the branch

controller again.

Put the keyswitch back to NORMAL.

DIAGNOSTIC INDICATION UNDER
APPLICATION SOFTWARE
Under Barclays software, when the controller is functioning normally, the six LEDs continuously flash, all ON
for five seconds and then all OFF for five seconds.

If a hardware error occurs, one or more ofthe diagnostic
LEDs will stay on while the rest keep flashing. The RUN
LED will stay ON. The LEDs have the following
meanings.

L1 ON - KMV11 failure
L2 ON - One or more KMV11 lines failed
L3 ON - One or more back office terminals failed
L4 ON - Line to computer-center failed

L5 ON - RD52 failed

L6 ON - Invalid, should not occur
For an applications software error the LEDs will stop
flashing and a steady code will be displayed. If this is the
case, Barclays Support Services at Radbroke Hall should
be informed. LEDs are laid out as follows:

RD52 DRIVE
|
NOTE
The RDS52 has to be preformatted in the

DIGITAL branch office for use with RQDX1.
The formatter program must be ZRQBB? or
|
later.
The Read/Write PCB is not an FRU. If it is
defective, replace the complete RDS52 drive
assembly. Handle it gently at all times.

Allow 30 seconds between power-off and

handling the RD52, to permit the arm assembly
to lock in the landing zone, and the disk to
stop.

"To replace the RD52 drive, follow the step-by-step

guide below:

See Section 1 for access to the RD52.

Unscrew the four bezel screws (Figure 36) and
remove the bezel from the drive base plate assembly.

Note the physical position of the RD52 and
cables. This will help you to re-install the drive.

Remove the crosshead screw B (Figure 36), and
the two mounting screws underneath the drive
base plate. Lift out the RD52 and cables, and the
RD52 plate (distance plate).

Remove the mounting bracket (crosshead screw A).

Replacement RD52s are supplied with a skid
plate (Figure 37) attached. Remove the skid plate
and transfer it to the defective drive.

Check that jumper DS3 only is installed on the
PCB of the new RD52 (Figure 38).

Transfer the mounting bracket (screw A, fingertight) to the new drive.

Transfer the cables to the new drive.

MAINTENANCE GUIDE (MKIll)

The following sequence assumes that a representative
of Barclays Management Service Department (MSD) is
on site. If not, miss out steps 2 and 8.
1.

Make contact with the bank manager’s assistant.

Make contact with the MSD representative.

Unpack and check controller and installation
materials. Install controller in Lions trolley.
Connect controller power cable to the power
distribution panel on Lions rack. Do not connect
to terminals or to the network.

Setkeyswitchto TEST. Run power-up diagnostic
with loopback connectors in the communications
connectors.

Swap KMVI11 loopback connectors (see next

page). Repeat the diagnostic.

Connect LA12 to console connector. Run XXDP+
diagnostics for each device (see next page).

Run DECX/11 (see next page).

If all tests OK, make connections to network and
to terminals.

ACCESS TO THE BARCLAYS CONTROLLER

In general, Barclays branch controllers are installed in a
Lions rack, which contains modems and other equipment.
This rack is NOT a DIGITAL product. In order to get the
controller out, you need to remove a retaining strut in the
rack. Lift one end of the strut while applying outward
pressure to the adjacent vertical leg. See Figure D-1 for
detail. Then do the same at the other end. You can now

BARCLAYS FAULT REPORTING PROCEDURE

When the bank system appears to be defective, the

response of bank staff depends on the symptom.

Bank staff will usually report problems to Support
Services at Radbroke Hall, Knutsford. Network Control
at Wythenshawe, Gloucester, or Greater London may

also be contacted. However, if the same fault (or a similar
fault) has been previously handled by DIGITAL, bank
staff may call DIGITAL Field Service direct.

If DIGITAL is not called directly, Support Services
and/or Network Control will cooperate with bank staff to
identify the defective unit. If necessary, bank personnel
will be told to press the INT button and to report the LED
status. If the controlleris thought to be defective, Suppert
Services will call DIGITAL Field Service.

Field Service should contact Support Services when
they arrive on site. The telephone number is 0565-3888,
. ext 2127.

MAINTENANCE GUIDE (MKIl)

APPENDIX F

MARK AND FIRMWARE REVISION CODES

To make it easier to recognize a controller and its
firmware, diagnostic LED sequences, from the MKII
update onward, will include codes to identify the mark and
the firmware revision. During the code which follows the
flashing pattern, LEDs L1 L2 L3 and L4 L5 L6 display
octal codes with the meanings given in Table F-1. An
example of the code for a MKIII controller with version 1
firmware is given below the table.

controllers will also be in the BA123 box. Therefore,

although they will function as MKIlIs, they may look like
MKIVs.

MKIIIs and MKIVs can be identified by identity

boot from the RX50.

. See Table H-2 for LED codes that control the
loading of software. Load the Customer Software
diskettes (Diskl to Diskn) into the other RX50.
The LED codes of Table H-2 will tell you when to
load each software diskette.

. When Diskn has been read, a ‘Load Complete’
code will be displayed. R&fizévgbiskn.

. The LED code will tell you to load the Additional

Software diskette or the Branch Commissioning
diskette. Load them in that order if you have both.

. When the appropriate ‘load complete’ code is

displayed, remove all diskettes from the RX50s and

press the INT button.
8. Put the keyswitch to

NORMAL.

After boot, if the branch controller is functioning
normally, the six diagnostic LEDs will continuously
flash, all ON for five seconds and then all OFF for five
seconds.
