Service Conditions

(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 no t s toring 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 (Majo r Alarm, Minor Al arm, or No Alarm Indicat ion) ca n be prog r ammed b y

CMEA Y=2 for each fault kind.

CMEA

DESCRIPTION DATA

Enable the fault information storage feature.

Specify the processing at the time of fault stor a ge memory overflow .

Assign which kind of fault information is stored into the fault information memory, and which kind of fault indicates an alarm.

NOTE 1:

NOTE 2:

Even if the external alarm may be set as MN or MJ alarm for system initialized (1st data=01), no alarm is output in th e case of Power On, Reset key operated, in itialization from the MAT/ CAT, and initialization by MP SW3 switch selection.

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 info rmation is to be registered into Fault Memory. In this case, Alarm K ind ca nn ot be changed.

DIAGNOSTICS

General Description

To assist maintenance personnel, this feature provides diagnostic capabilities such as fault code generation, device status information and alarm information recording, which can be accessed from the MAT or the CAT.

Service Conditions

(1) The following station status information can be displayed on the MAT or the CAT by direct

command:

• Idle

• Line Lockout

• Dialing

• Tone Trunk Connection (reorder tone, busy tone, service set tone, etc.)

• Types of Connection (station-to-station, three-way calling, voice calling, holding, etc.)

• Destination number (trunk number, register number)

• Short circuit on line

(2) The following trunk status information can be displayed on the MAT or the CAT by direct

command:

• Idle

• Ringing in

• Incoming queue to Attendant Console

• Holding

• In a tandem connection

• Incoming queue to UCD

• Dialing

• Receiving dialed digits

CHAPTER 1 MAINTENANCE SERVICE FEATURES

Diagnostics

(3) The following information is st ored and can be displayed on the MAT or the CAT using a

memory dump command in hexadecimal format:

• 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)

(4) 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.

CHAPTER 2 TROUBLESHOOTING

Precautions

Turning Power ON

CAUTION

1. When the operating pow er is being sup plied to the PZ- PW121 card, do not plug/unpl ug this circuit card into/from its mounting slot.

2. When the system is configured with two or more PIMs, the BUS cab le provides gang con trol 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, howe ve r , that the batte ry continues to charge e v en under these c ircumstances.

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).

240V100V/120V

• Make sure that the battery mode selector switch is positioned as shown below to meet the kind of battery:

SW101

OFF

1 : Not used 2 : ON (SEAL/FLOAT2) OFF (OPEN/FLOAT1)

(2) 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.

CHAPTER 2 TROUBLESHOOTING

Precautions

Turning Power OFF

(1) Before turning power off, make sure that all line/tr unk cards are not operating by no busy

lamps indication.

(2) Turn the SW1 switches of all the PZ-PW121 cards to O FF. First, turn OFF PIM0. Then, turn

OFF PIM1 to PIM7.

CHAPTER 2 TROUBLESHOOTING

Fault Detection

(1) Fault Detection b y Al arm 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 iden- tifies the alarm indication lamps on each ci rcuit card. F or details of l amp indication on circuit cards, refer to the Installation Procedure Manual.

(3) Fault Detection b y Complaint from Station Use r or Operator

When you receive a complain t about a problem f rom a sta tion us er or an o perator, collect as much inf ormation on the prob lem as possib le, and th en troublesh oot the prob lem according to the procedure in "Troubleshooting by Contents of Complaint" on Page 95.
