b) Conduct the Q4ARCPU reset operation.
c) After conducting reset return the separate mode switch to the
backup mode side.
2) When in the output hold mode
a) urn the bus switch module's separate mode switch to the
separate mode side.
b) Turn the bus switching module's output hold/reset setting switch

(6) When holding (retaining) the output when a CPU module stoppage error
occurs in a standalone system

POINT
•
In redundant systems the CPU module's output hold/reset setting switch
settings are invalid.
•
To hold output in a redundant system,, conduct the setting using the bus
switching module setting switch. (Refer to the Q4ARCPU User’s Manual)
In redundant systems, the only output that can be held is that of the
modules in the expansion base.
The output from modules in the basic base cannot be held.
When using the output hold mode take the following precautions.
