Using the Diagnostic Module
The Diagnostic Module can be used alone, with suspected faults shown
on the module’s display, or used interactively with a data terminal. The
preparation for both methods of testing is the same. Separate instructions are provided for each method when diagnostic testing begins.
WARNING: Whenever you power up the system or insert and
remove modules, follow the procedures below to turn the power
switch(es) on the Power Module(s) On and Off.
Power On:
If your system has an expansion carrier, first turn On the power
switch on its Power Module. Then turn On the power switch on
the basic carrier’s Power Module.
●
If your system only has a basic carrier, turn On the power switch
on its Power Module.
●
Power Off:
If your system has an expansion carrier, turn Off the power switch
on the basic carrier’s Power Module first, then turn Off the power
switch on the expansion carrier’s Power Module.
●
If your system only has a basic carrier, turn Off the power switch
on its Power Module.

PREPARING FOR DIAGNOSTICS
1 Get a pencil and paper.
You may want to record diagnostic messages while the tests are running.
2 Clear users from the system.
Before testing the system, make sure that there are no active calls.
To do so:
●
●
●
Slide the administrator/attendant console’s T/P switch to P (program mode).
Touch Conference twice.
Lights flash next to Adm Pool, Adm Tel, Message, and Speaker.
Touch Message.
The lights next to Adm Pool, Adm Tel, and Speaker stop flashing.
The green light next to Message remains on.
iss 2, cib3101-3
●
Dial the 4-character code #299.
If the light next to Message flashes, one or more calls are active.
When the light becomes steady, the system is idle and ready for
testing.
3
Check system configuration.
The following modules should be in the basic carrier and at least
partly functional for the diagnostics to be fully effective:
●
Power Module (must be fully functional)
●
Processor Module
●
4
An analog line module (such as, the 4 Line 8 Voice Terminal
(408) Module, 4 (400) Line Module, or 8 (800) Line Module) must
be present for analog loopback testing. Refer to the “Command
Section” of this document for more information about the loopback test.
Make sure that all modules in the carrier(s) are firmly seated.
This will ensure proper contact between each connector on the back
of the module and its mating card edge connector on the backplane.
5
Install Diagnostic Module.
A Prepare the carrier(s) following these instructions:
●
Remove the front cover from the carrier(s).
●
Make sure that its rightmost slot contains a module. If it does
not, insert the empty module (provided with the basic carrier
assembly) in this slot to support the Diagnostic Module.
B Prepare the Diagnostic Module for installation by following these
instructions:
●
●
Locate the metal slide attached to the upper right leg of the
module.
Loosen the metal slide’s screw. Pull the metal slide away
from the module until it is fully extended (Figure 2). Tighten
the screw.
C Insert the Diagnostic Module following these instructions:
CAUTION: The following steps will cause all calls in progress
to be terminated.
NOTE: Do not remove modular cords from modules at this time.
Removal of modular cords is only necessary when executing the
loopback test and when certain Diagnostic Display Messages are
displayed.
●
Turn Off the power switch(es) on the Power Module(s).
iss 2, cib3101-4

FIGURE 2 Installing the Diagnostic Module
Using the Diagnostic Module Alone
1 Set the Normal/Test switch to Test.
“DIAG” followed by the Diagnostic Module’s firmware version number
appears momentarily on the display. If it does not, see “When Diagnostics Will Not Start” on Page 12. When the problem is cleared,
continue with Step 2 of this section.
iss 2, cib3101-5
2
Diagnostics begin.
The modules in each slot are identified on the Diagnostic Module’s
display in turn as each module is tested. All modules are identified
by slot numbers, except the following: the Processor Module is identified as “CPU,” the Diagnostic Module by “DGM,” and the Feature
Module by “MEM”. The “*ALL” message appears when a trouble
cannot be isolated to a particular slot. The “*INT” message appears
when an unexpected interrupt occurs. If a module testable by diagnostics is present, but it is not identified, the Diagnostic Module is not
aware of its presence. First, remove the module and make sure that
the contacts on the module’s connector and on the backplane’s card
edge connector are not damaged. If you find damaged contacts,
contact your equipment supplier. If the contacts are not damaged,
insert the module making sure that it is firmly seated. If the module
is not identified on the next test sweep, replace the module.
After all possible tests have been executed the “DIAG” message
reappears as a new sweep of tests begins. Since the proper operation of some tests depends on the successful completion of others,
possible tests will vary with the type of faults encountered. For
example, line and voice terminal modules will not be tested if a fault
is found in the Processor Module because a working processor is a
prerequisite for line and voice terminal module tests.
Test sweeps will repeat continually until a fault is found or the
Normal/Test switch is set to Normal.
3
Resolve diagnostics messages.
If an asterisk (“*”) appears on the left side of the display, follow these
steps:
A Write down the message next to “*”. This message identifies the
module that is the most likely source of trouble.
B Hold down the Test Detail button and write down the message.
C Look up the display message in the “Diagnostic Display Messages” Section and follow the recommended action.
D Press the Next Test button to continue testing.
●
●
If you wish to begin a new sweep of tests (from the “DIAG”
message onward), press the Test Detail button while no “*” is
present on the display.
If you wish to skip a particular module test, press the Next
Test button while no “*” message is present on the display.
The message “STEP” will appear after you press Next Test
and testing will begin.
iss 2, cib3101-6
NOTE: The Processor Module test (shown on the display as
“CPU”), the Diagnostic Module test (“DGM”), and the “ALL”
test cannot be skipped.
4
Repeat diagnostics.
When “DIAG” and the firmware version number reappear on the
display, a new sweep of testing begins. Testing continues until you
exit test mode.
5
Exit test mode.
●
At the Diagnostic Module set the Normal/Test switch to Normal.
Diagnostic testing ceases and normal call processing resumes.
●
Slide the administrator/attendant console’s T/P switch to the
center position.
●
Turn Off the power switch(es). Remove the Diagnostic Module
and retract the metal slide on the upper right leg of the module.
●
Turn On the power switch(es). Replace the front cover(s).
Using the Diagnostic Module With a Data
Terminal

FIGURE 3 Connecting a Data Terminal
2 Set the Normal/Test switch to Test.
“DIAG” followed by the firmware version number appears momentarily on the Diagnostic Module’s display. If it does not, see “When
Diagnostics Will Not Start” on Page 12. When the problem is
cleared, continue with Step 3 of this section.
3 Wait until the “REMT” and “DIAG V[number]” messages appear.
When the Diagnostic Module is in interactive mode (ready for commands), “REMT” (remote interface active) appears on the display.
The prompt “DIAG V[number]” appears on the terminal screen.
4 Display the command menu.
Type “help” or “?” and press RETURN to display a list of commands.
(A list of commands and their definitions begins on Page 10.)
5 Execute a diagnostic test sweep.
To execute a single sweep of tests on the system, type “sweep” and
press RETURN. The modules in each slot are identified on the Diagnostic Module’s display in turn as each module is tested. All modules
are identified by slot numbers, except the following: the Processor
Module is identified as “CPU,” the Diagnostic Module by “DGM,” and
the Feature Module by “MEM”. The “*ALL” message appears when
a trouble cannot be isolated to a particular slot. The “*INT” message
iss 2, cib3101-8
appears when an unexpected interrupt occurs. If a module testable
by diagnostics is present, but it is not identified, the Diagnostic
Module is not aware of its presence. First, remove the module and
make sure that the contacts on the module’s connector and on the
backplane’s card edge connector are not damaged. If you find damaged contacts, contact your equipment supplier. If the contacts are
not damaged, insert the module making sure that it is firmly seated.
If the module is not identified on the next test sweep, replace the
module.
Since the proper operation of some tests depends on the successful
completion of others, possible tests will vary with the type of faults
encountered. For example, line and voice terminal modules will not
be tested if a fault is found in the Processor Module because a working processor is a prerequisite for line and voice terminal module
tests.
The sweep of tests lasts 45 seconds to 3.5 minutes, depending on
the number of modules present. The system exits interactive mode
during testing. When the prompt “DIAG V[number]” appears on the
terminal screen, the test sweep is complete and the system is again
in the interactive mode.
6
Interrupting a test sweep.
To interrupt testing and return to the interactive mode, press
RETURN. (You may have to press it more than once.) The prompt
“DIAG V[number]” appears after the current diagnostics test is completed. It takes up to 30 seconds for the current test to complete. To
exit the interactive mode and resume the interrupted sweep of tests,
type “resume” and press RETURN.
7
Display test results and resolve diagnostic messages.
To display a table of faults collected during the test sweep, type
“errors” and press RETURN. Refer to the “errors” entry in the “Command Menu” Section of this booklet for more information about the
faults.
Look up the slot number and detail message in the “Diagnostic
Display Messages” Section and follow the recommended action.
Make sure that the module is properly seated and that the edge
connector’s contacts are not damaged. If you find damaged contacts, contact your equipment supplier.
