NDA-24307 CHAPTER 7 Page 567 Issue 1 CHAPTER 7 ROUTINE MAINTENANCE PROCEDURE 1. GENERAL When a fault has occurred in the system, (for example when a fault has occurred to No. 1 circuit on the 16LC card), the stations connected to No. 1 circuit become unserviceable. When the 16LC card has been replaced with a spare to analyze the cause of the fault or to repair the fault, other normal lines also become unserviceable. As in this example, even when the fault is restricted to a single component, it very often harms the system operations as a whole. Even if the system is operating normally, it is necessary to perform a routine check to prevent a fault occurrence before it is too late to discover any latent cause of a fault. This chapter categorizes the routine maintenance procedures of the PBX into the following three types, and ex- plains the minimum required work steps and precautions pertaining to each of the three procedures. Daily Maintenance Procedure Monthly Maintenance Procedure Quarterly Maintenance Procedure 1.1 Flow of Procedures The scheduling of routine maintenance (daily, monthly, quarterly) will vary with each installation and organization. Figure 7-1 shows the flow of the routine maintenance procedures.

NDA-24307 CHAPTER 7 Page 569 Issue 1 ROUTINE MAINTENANCE PROCEDURE 2. ROUTINE MAINTENANCE PROCEDURES This section explains general routine maintenance procedures to be performed on a daily, monthly, and quarterly basis. Table 7-2 lists each procedure according to the time each procedure is to be performed. Use the Reference Section to locate the detailed procedure. Table 7-2 List of Routine Maintenance Procedures TIME PROCEDURE REFERENCE SECTION REMARKS Daily Check the temperature and relative humidity in the switch room.Section 3.1, Check of Ambient Conditions in Switch Room Check to see if any of the alarm indicator lamps on the TOPU are lit.Section 3.2, Alarm Check Check the operating status of the MAT and the printer, remaining quantity of paper, etc.Section 3.3, MAT/Printer Check Check to see if a system message indicating a fault is displayed.Section 3.4, Collection of System Messages Check whether any station is in lockout state.Section 3.5, Display of Locked- out Station Check whether the FANU is operating normally.Section 3.6, Fan Unit Check Monthly Generate an alarm and check whether an indica- tion appears on the TOPU.Section 3.7, Alarm Tests Check the conditions of the rectifier and batteries.Section 3.8, Main Power System Check Check trunk circuits individually. Also check the RGU circuit in the PWR Supply of each Module.Section 3.9, Trunk RGU Check Check each operation and lamps of ATTCON/ DESKCON.Section 3.10, ATTCON/ DESKCON Check Quarterly Check the CPU, TSW, and line/trunk Port Microprocessors (PMs).Section 3.11, System Check

If the temperature or the humidity is outside the allowable range, adjust the air conditioner.Check whether the room temperature is within the range of 5°C (41°F) to 30°C (86°F). Check whether the relative humidity in the room is within the 15% to 65% range. START END
CHAPTER 7 NDA-24307 Page 572 Issue 1 ROUTINE MAINTENANCE PROCEDURE 3.2 Alarm Check Check alarm indications on the TOPU. If an alarm is indicated Check whether the alarm lamp on the power supply of any module is lit. Check whether an alarm lamp is lit on any circuit card(s). Alarm recovery Refer to Chapter 5, diagnose the alarm and perform the indicated recovery procedures. START END
