    CHAPTER 7 WORK AFTER INSTALLATION TESTS
    This chapter explains various kinds of work and site cleaning, etc. which the installer must perform after com-
    pletion of 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 Section explains the method of creating backup of the Office Data and the method of protecting the Office
    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 becomes 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 most up-to-date data at all times, entries into
    the office data programming sheets must be made in pencil.
    2. Floppy Disks 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,
    an FD containing the office data before the change and one containing the data after the change should be
    kept on hand. The FD containing the data before the change allows the technician to restore the previous
    (running) condition if the system will not operate properly with the new data.

    Note:
    Cautions pertaining to Floppy Disks.
    (1) Do not place a heavy object on an FD or the FD will be damaged.
    (2) When taking an FD out of its protective envelope, hold the top edge of the disk and gently pull it out.
    (3) Do not expose the FD to direct sunlight or to a high temperature (above 65°C (150°F)).
    (4) Do not pinch the FD with a clip.
    (5) Do not touch the recorded surface of the floppy disk with bare hands; fingerprints left by bare hands
    will attract dust.
    (6) Avoid cleaning of the floppy disk.
    (7) Do not place the floppy disk near a magnet, etc. If an FD is exposed to a magnetic field of more than
    50 Oe, the data on the disk is likely to be altered or destroyed.
    (8) Do not bend the floppy disk.
    (9) Do not apply force to outer edge of the floppy disk.
    2. PREPARATION OF TEST RESULT REPORT
    When submitting a report of test results to the end user or when performing test with customer’s representatives
    attending, prepare Test Result Report and record the test results into the prepared Test Result Report.
