General Description
This feature stores fault information into the Fault Store Memory and displays the fault information on the Maintenance Administration Terminal (MAT) or the Customer Administration Terminal
(CAT). The display format is shown below:

(1)
Printout of fault information is possible through the printer connected to the MAT.
(2)
The maximum number of fault information that can be stored is 64. If the stored information
exceeds 64, the storing method (either overwriting new data or not storing new data) can
be selected by CM08>451.
(3)
To provide external alarm indication, equipment such as an Alarm Display Panel must be
installed. External alarm indication is provided using a contact to ground at the main
distribution frame. One contact is needed for minor alarms, and one contact is needed for
major alarms.
(4)
The alarm kind (Major Alarm, Minor Alarm, or No Alarm Indication) can be programmed by
CMEA Y=2 for each fault kind.

Enable the fault information storage
feature.
(1) 450
(2) 1 : To be provided
Specify the processing at the time of
fault storage memory overflow.
(1) 451
(2) 0 : No fault information is registered
in case of fault memory overflow

CMEA
Assign which kind of fault information
is stored into the fault information
memory, and which kind of fault indicates an alarm.
NOTE 1: Even if the external alarm
may be set as MN or MJ
alarm for system initialized
(1st data=01), no alarm is
output in the case of Power
On, Reset key operated, initialization from the MAT/
CAT, and initialization by
MP SW3 switch selection.
A
NOTE 2: The External Alarm Kind for
“Number of faulty trunks
was more than predetermined number” is assigned
by CM42>06, 07. When
CM42>06, 07 is assigned,
the 2nd data of CMEA Y=2
simply means the fault information is to be registered
into Fault Memory. In this
case, Alarm Kind cannot be
changed.

The following information is stored and can be displayed on the MAT or the CAT using a
memory dump command in hexadecimal format:
•
•
•
•
(4)
Program address where an endless loop has occurred
Last initialization time for main program
Last initialization time for firmware program
The reason for initialization (power-on, RESET key, endless loop, rotary switch, command
from MAT or CAT)
The PBX has a built-in patrol program that monitors the status of all connected devices.
Additionally, when no response or an invalid response from a device is received, this
program stores in memory the slot number of that device. From the MAT or the CAT, a
maintenance person can read the slot number of any device that does not respond to the
main processor or provides an illegal status to the main processor.
Programming Procedure
No programming is required.

Service Conditions
(1)
Use CM43 Y=2 to assign the time (year, month, date, time) of periodic inspection; for
example, battery exchange.
(2)
When the time of periodic inspection comes, the Dterm alarm function key lights when the
setting is the MJ alarm, or flashes with 60 IPM when the setting is the MN alarm. At the
same time, the alarm display panel can indicate the alarm.
(3)
(4)
Up to two Dterms in a system can indicate the periodic alarm.
The alarm indication can be cleared by assigning CMEA Y=1 from CAT/MAT.

CHAPTER 2 TROUBLESHOOTING
Precautions
Turning Power ON
CAUTION
1. When the operating power is being supplied to the PZ-PW121 card, do not plug/unplug this
circuit card into/from its mounting slot.
2. When the system is configured with two or more PIMs, the BUS cable provides gang control
for the PZ-PW121 card of PIM0 and other PIMs. Therefore, if the power of PIM0 is off, no
power is supplied to the whole system even when the power switch(es) of other PIMs are
left on. Note, however, that the battery continues to charge even under these circumstances.
3. Do not turn off the PZ-PW121 card on PIM1 to PIM7 when the system is operating.
(1)
Check the switch position of each PZ-PW121 card before turning power on.
• Make sure that the AC120V/240V selector switch is positioned to appropriate voltage for
each country (AC120V or AC240V).

Turn the SW1 switches of all the PZ-PW121 cards to ON. First, turn ON PIM1 to PIM7.
Then, turn ON PIM0 last of all.

Precautions
Turning Power OFF
(1)
Before turning power off, make sure that all line/trunk cards are not operating by no busy
lamps indication.
(2)
Turn the SW1 switches of all the PZ-PW121 cards to OFF. First, turn OFF PIM0. Then, turn
OFF PIM1 to PIM7.

Fault Detection
(1)
Fault Detection by Alarm Indication
When a fault occurs in the system, you can detect the fault by a Major (MJ) alarm or Minor
(MN) alarm indicated on the AC/DC PWR card or by the external Alarm Display Panel.
(2)
Fault Detection by Lamp Indication on Circuit Cards
When a fault occurs in the system, you can detect the fault by lamp indication on circuit
cards, such as a Major (MJ) or Minor (MN) alarm indicated on the MP card. Table 2-2 identifies the alarm indication lamps on each circuit card. For details of lamp indication on circuit
cards, refer to the Installation Procedure Manual.
(3)
Fault Detection by Complaint from Station User or Operator
When you receive a complaint about a problem from a station user or an operator, collect
as much information on the problem as possible, and then troubleshoot the problem according to the procedure in "Troubleshooting by Contents of Complaint" on Page 95.

CHAPTER 2 TROUBLESHOOTING
Fault Diagnosis and Troubleshooting
EXPLANATION OF SYMBOLS IN TROUBLESHOOTING PROCEDURE
The following markings explain the instruction marks used in the troubleshooting procedures.
CHECK
: With respect to the item indicated on the right side of this mark, perform a check
or the required work. If an abnormality is found, take the required remedial action,
such as repair, replacement, etc.
REPLACE : Replace the equipment or device (considered to be the fault) indicated on the right
side of the mark with a spare and confirm the recovery of the fault.
HOW TO FOLLOW THE “TREE”
The troubleshooting procedure is explained in the form of a “Tree”. Troubleshooting can be performed accurately, as well as efficiently, by following the related “Tree” path according to the information available on the fault. In the following information gives a step-by-step explanation
about how to use the “Tree.”
Step 1:
The maintenance personnel gathers information concerning the fault and selects the
tree to use from Figure 2-4.
Step 2:
In the selected tree, search the item concerned by checking the symptom one by one
following the tree downward from the “START” point. If the related item has not been
found, gather more detailed information concerning the fault.
Step 3:
The items indicated by the CHECK mark on the right side of the items concerned
suggest elements that are possibly responsible for the fault. Check each of these items.
If an abnormality is found, perform the necessary remedial action such as repair, replacement, etc.
Step 4:
If the fault is not recovered after a check was made on the items indicated by the
CHECK mark and necessary actions were taken, replace the circuit card(s) and other hardware indicated by the REPLACE mark with spare(s). In this case, every time
hardware is replaced with a spare, check whether the fault is recovered.
