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)

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.

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.

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.
