12.2.4 System Initialization by Keys on CPU Front Panel
This initialization executes when the INITIAL key on the TOPU cannot be used.
The CPU’s active status must be confirmed before executing this type of initial-
ization. Perform the procedure in Table 6-17.

12.2.5 System Initialization by SINZ Command
The entire system can be initialized by execution of the SINZ command from the MAT, which is useful
for maintenance technicians who have to control the system from a distant location. Perform the pro-
cedure in Table 6-18.
Table 6-18  System Initialization by SINZ Command Procedure
ACTION REMARKS
Use SINZ command to execute 
initialization.

END
Execution of Initialization
Confirm the following lamp indications:
[CPU DSP #0] CPU OPE: steady-green
IMG0-3: flash (green)
[CPU DSP #1] IMG0: flash (green)
Use ATIM command to adjust date and 
time.Note:When the system is 
initialized, the MAT is 
once disconnected. Then, 
log in to system again. When the initialization com-
pletes, ACT0 lamp lights
green and ACT1 lamp goes
OFF on EMA (PH-PC40)
card.For information about SINZ
command, see Chapter 8.

12.2.6 Peripheral Equipment Initialization (Line/Trunk Initialization)
Line/trunk initialization can be divided into two types: initialization on an indi-
vidual channel basis and initialization on a circuit card basis. Follow the proce-
dure in Table 6-19.

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 must be stopped due to module expansion work, etc. In preparation for such a case, this
section explains the procedure for stopping the system and turning ON the power supply.
12.3.1 How to Turn On Whole System
Figure 6-59   How to Turn ON the Whole System Note:
Start from bigger number depending on configuration of IMG stack.
(i.e. 1.5 stack: IMG3       IMG2       IMG1       IMG0).
Confirm SENSE switch on DSP of Active 
CPU is set at 2 (DM Load Restart).

12.3.2 How to Turn OFF Whole System
Confirm that the memory data has been backed up on the HD before turning OFF the system power.
When turning OFF the power supply, follow the procedure shown below.
Turn OFF the power supply in the uppermost PIM of the IMG stack whose number is larger. Then
move down to the bottommost PIM and repeat the procedure for the smaller IMGs.

(1) Turn OFF -48V SW on DPWR (first) and PWR (next) cards in PIM3 of IMG3.
(2) Repeat (1) for PIM2, PIM1, PIM0 (IMG3) in this order.
(3) Turn OFF -48V SW on DPWR (first) and PWR (next) cards in PIM3 of IMG2.
(4) Repeat (3) for PIM2, PIM1, PIM0 (IMG2) in this order.
(5) Turn OFF -48V SW on DPWR (first) and PWR (next) cards in PIM3 of IMG1.

12.4 System Start-Up
The system start-up procedures consist of the following types:
Procedure #1 (see Table 6-20) Executed when the Basic Software and Application Software
have already been installed in the HD. Office Data has not
been installed.
Procedure #2 (see Table 6-21) Executed when the Basic Software, Application Software and
Office Data have been already installed in the HD.
Note:
For the start-up procedure in case any Basic Software, Application Software and Office Data have not been in-
stalled in the HD, refer to the Installation Manual (4-IMG Type).
