NDA-24307 CHAPTER 6 Page 553 Issue 1 SYSTEM OPERATIONS Table 6-16 System Initialization by Phase 1 Restart Procedure ACTION7SEG LED/OPE LAMP/KEY SETTINGS Note: The TOPU used for intialization varies depending on the type of initialization. Initialization of Whole System: TOPU of ISW Initialization of ISW: TOPU of ISW Initialization of LN: TOPU of IMG0 (each LN) STARTFor lamp indication on DSP, refer to Table 6-10. For the face layout of TOPU, refer to for ISW and for LN. ISW: Figure 6-64 LN: Figure 6-65 CPU OPE and IMGn lamps on both DSP go OFF. STATUS LED (right) on the CPU is ON. STATUS LED (right) on the DSP of CPU is ON. For lamp indications on DSP, refer to Table 6-10. STATUS LED (right) on the DSP of active CPU is ON. (ON LINE) Set the keys on the TOPU as follows. PROGRAM KEY→NON LOAD SYSTEM DATA KEY→NON LOAD END HD Initial System Initialization System starts up again. Turn ON the EFFECT key on the TOPU. Press the INITIAL START button on the TOPU. Set the INITIAL SELECT keys as follows. Initialization of Whole System→ Set the key to SYSTEM side Initialization of ISW→ Set the key to SELF side Initialization of LN→ Skip this step Confirm the system is operating normally. Set SENSE Switch on the DSP of CPR to 3.
CHAPTER 6 NDA-24307 Page 554 Issue 1 SYSTEM OPERATIONS 12.2.4 System Initialization by Keys on CPU Front Panel This initialization executes on a node (ISW/LN) basis when the keys on the TOPU cannot be used. The CPU’s active status must be confirmed before executing this type of initialization. Figure 6-67 System Initialization by Keys on CPU Front Panel ATTENTIONContents Static Sensitive Handling Precautions Required Use ATIM/ATIMN command to adjust date and time. Confirm ACT 0 lamp lights green again.Confirm ACT 1 lamp lights green again. Press CPU RST key on the DSP of CPU 0.Press CPU RST key on the DSP of CPU 1. Confirm SENSE switch on the DSP of CPU 1 is 2 (DM Load Restart). Confirm SENSE switch on the DSP of CPU 0 is 2 (DM Load Restart). (ACT0 lights green.)(ACT1 lights green.) Check ACT0/ACT1 lamps on the EMA card. START (CPU 0 is being initialized.)(CPU 1 is being initialized.) END EMA: PH-PC40
NDA-24307 CHAPTER 6 Page 555 Issue 1 SYSTEM OPERATIONS 12.2.5 System Initialization by SINZ/SINZ1 Command The entire system can be initialized by execution of the SINZ/SINZ1 command from the MAT, which is useful for maintenance technicians who have to control the system from a distant location. When initializing the system on a node (ISW/LN) basis, use SINZ command. When initializing the whole system, use SINZI command. Figure 6-68 System Initialization by SINZ Command START END For more information about the SINZ/SINZI command, see CHAPTER 8: “MAINTENANCE COMMANDS.” Refer to 1 or 3 of Table 6-9 for DSP#0, and 2 or 4 of the table for DSP#1.Use the SINZ/SINZI command to execute initialization. Use the ATIM/ATIMN com- mand to adjust the date and time. Confirm lamp indications on the DSP of CPR. Note:When the system is initialized, the MAT is once disconnected. Then, log in to the system again.
CHAPTER 6 NDA-24307 Page 556 Issue 1 SYSTEM OPERATIONS 12.2.6 Peripheral Equipment Initialization (Line/Trunk Initialization) Line/trunk initialization can be divided into two types: initialization on an individual channel basis and initialization on a circuit card basis. Follow the procedure in Table 6-17. Table 6-17 Line/Trunk Initialization Procedure ACTION REMARKS ATTENTIONContents Static Sensitive Handling Precautions Required Return MB switch to the previous position after the MB lamp has turned ON. Turn the MB switch UP on the circuit card. Use RLST command. (Refer to Chapter 8) START END END Is initialization on individual channel basis or on circuit card basis?Circuit card basis Individual channel basis Note:When initializa- tion executes on a circuit card basis, all channels on the cir- cuit card are placed into make-busy state.
NDA-24307 CHAPTER 6 Page 557 Issue 1 SYSTEM OPERATIONS 12.3 How to Turn ON/OFF Whole System A switching system, once put into service, is seldom stopped. However, there may be a case when a switching system, while in service, must be stopped due to module expansion work, etc. In preparation for such a case, this Section explains the procedure for turning ON the power supply.
