If a console is attached but nothing
is displayed on it, follow the steps
associated with "All display
problems" in the Entry MAP tables.
If selection screen(s) can be seen
on the terminals and the
appropriate key on the input device
associated with the desired display
or terminal is pressed, within 60
seconds, but there is no response
to the keystroke:
v If selecting the console with a
keyboard attached to the
system, replace the keyboard. If
replacing the keyboard does not
fix the problem, replace the
primary I/O backplane.
v If selecting the console with an
ASCII terminal, suspect the
ASCII terminal. Use the problem
determination procedures for the
terminal. Replace the primary I/O
backplane if these procedures
do not reveal a problem.
Note: Terminal settings should
be set to:
– 9600 Baud
– No Parity
– 8 Data bits
– 1 Stop bit
