SYSTEM STARTUP
CHAPTER 4 SYSTEM STARTUP
1. GENERAL
This Chapter describes the initial startup procedure and the diagnosis procedure after installing PBX. Before be-
ginning the system startup, thoroughly read Section 2., “PRECAUTIONS BEFORE BEGINNING SYSTEM
STARTUP” of this Chapter, and observe the precautions while performing the system startup. Neglecting the
precautions may delay the system cutover or may damage the system equipment.
2. PRECAUTIONS BEFORE BEGINNING SYSTEM STARTUP
1. The system is to be started up using the basic system data.
2. When starting up the system, it is necessary to start up the MAT.
3. The following preparatory steps must be completed before the tests are executed:
• All circuit card switches should be correctly set.
• Flat cables should be securely connected.
• CHAMP connectors should be securely connected.
• All connector-ended cables should be secured at both ends.
• The –48 V (Blue) and G (Red) power supply leads must be correctly connected.
• An earth lead (less than 10 ohms) must be connected to the communication ground.
• The installer should confirm at this point that all installation steps have been completed.
4. Do not place any object (a tool, manual, etc.) on top of the Module Group or within a unit (module).
• An object such as a book, when placed on top of the Module Group, will adversely affect heat dissipa-
tion from the Module Group.
• If an object placed on top of the Module Group or left within a unit (module) falls out, it may cause
backplane pins, circuit cards, etc. to short-circuit.
5. Before initially turning ON power to the system, read the Power On Procedure (NAP-200-019).
• Until the normal operation of all circuit cards has been confirmed, leave power ON only during testing.
6. Observe the temperature in the switch room.
• Does the air-conditioning function properly at night?
• Does the temperature fluctuate constantly because people go in and out frequently, or rise above the rec-
ommended level due to excessive heat being generated by any single piece of equipment?
• The fan should be left ON constantly until the installation tests are completed.
7. A floppy disk (FD) copy of the programmed Office Data should be created. If the backup is not stored, and
the contents of the Data Memory are accidentally altered or destroyed, all the Office Data will have to be
programmed again.
