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.

12.3 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.

12.3.2 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.

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,...
