Probable cause
Use A319 and A320 to identify the
Power Supply Unit with an error and
either correct the error or, if neces-
sary, replace the Unit.
Use A434 and A437 to identify the
Communications Unit with an error
and either correct the error or, if nec-
essary, replace the Unit.
Correct according to cause indicated
by FAL number (set by user).
Change the indicated setting to a
valid setting.
Execute the I/O Table Verify opera-
tion to find the problem location. Cre-
ate new I/O tables or replace the Unit
to match the registered I/O tables.
Check the Inner Board indicators.
