System Initialization and System Data Entry

1. System Initialization

ATTENTION

Contents Static Sensitive

Handling Precautions Required

There are two methods for System Initialization. The first method is to Clear All Data, except LEN0000 as a CAT terminal, and then program the System Data. The second method is to use the Resident System Program, which causes the system to configure itself automatically to the default settings, wherever the line/ trunk cards are installed. Refer to the System Data Sheet for the default settings.

Turn on the “SW” switch on all the PZ-PW86 power units before initializing anything.

-The “ON” lamp must be lit on all the PZ-PW86 units.

1.1All Clear, Except LEN0000 CAT

Step 1: On the MP Card, set SW3 to “B” and press SW1.

Step 2: When the “MN” lamp on the system is lit, set SW3 to “0” and press SW1.

- Operating mode has been changed to ON LINE.

Note: Refer to the Circuit Card Manual for information on switch settings.

1.2 Resident System Program

Step 1: Mount the Line/Trunk cards into PIM.

Step 2: On the MP Card, set SW3 to “C” and press SW1.

-After 3 to 4 seconds, the “MN” lamp is lit.

-If the “MJ” lamp is lit, repeat the procedure of Step 2.

-The system has loaded the Resident System Program.

Step 3: Set SW3 to “0” and press SW1.

- Operating mode has been changed to ON LINE.

Note: Refer to the System Data Sheet for additional information on the Resident System Program and the initialization of the system without a MAT (enabling CAT mode).
