WORK AFTER INSTALLATION TESTS

CHAPTER 7 WORK AFTER INSTALLATION TESTS

This Chapter explains various kinds of work and site cleaning, etc. which the installer must perform after completing

installation tests so that the system can be cut over normally.

Upon completion of all the required tests, the technician must confirm or perform the following:

1. Office Data Management

2. Preparation of Test Result Reports

3. Mounting of the Front and Rear Covers

4. Attachment of Inter-frame Brackets

5. Site Cleaning

1. OFFICE DATA MANAGEMENT

This paragraph explains the method of creating backup of the Office Data and the method of protecting the Of-

fice Data.

The PBX executes various kinds of processing according to the results of access by the CPU to the Data Memory

in which the Office Data are stored. If the contents of Data Memory become faulty, it may result in erroneous

operation of the system or in a system down. If any part of the Office Data has been illegally changed, it may

also bring about a trouble the same as in the case of a fault occurrence to the Data Memory.

Thus, upon completion of the installation tests, ensure to create backup of the Office Data and provide a proper

measure of office data protection.

1.1 Preservation of Office Data

The following items should be kept at the job site after the installation test has been completed for preservation

of office data.

1. Office Data Programming Sheets

Since the office data programming sheets should reflect the latest data at all times, entries into the office

data programming sheets must be made with pencil.

2. Flash Card for Storing Data

If a major change is made to the office data, especially a change involving System Data (command “ASYD/

ASYDL/ASYDN”), the system may not function as expected afterward. To prepare for such an occurrence,

two flash cards should be kept on hand; one contains office data before the change, the other contains office

data after the change. The flash card containing the data before the change allows the technician to restore

the previous (running) condition if the system does not operate properly with the new data.
