This figure shows a system block diagram of ISW, which adopts a dual configuration. As seen in the figure, ISW
has the following terminals for the ACT/ST-BY changeover of dual system equipment:

Test Outline
Tests are to be performed to see if the system initialization can be executed on the following basis:
1. System Initialization on a Local Node basis (in each Local Node individually)
2. System Initialization in ISW only
3. System Initialization on a system basis (in ISW and all Local Nodes simultaneously)

1. System Initialization on a Local Node basis
Perform the system initialization test in each Local Node (LN), using the keys on the TOPU (refer to Figure 026-
1):

3. System Initialization on a system basis
Perform the system initialization tests in ISW and all Local Nodes simultaneously, per the flowchart cited be-
low. As in the flowchart, there are two kinds of method here; test via the keys on the TOPU of ISW, and test by
turning the power ON and OFF.
