Initial Customizing Procedure Form
Review this entire form before starting the customizing procedure. Unit
operating procedures are described in the 3270 Information Display System:
Operator's Guide, GA27-2890.
These procedures configure the 3274 Control Unit. If you do not get the
expected result in any step, start over at step
1.
If you have the same problem
a second time, check with your supervisor, or follow your local procedures.
There are four indicators, labeled 8421, on the 3274 control panel. The
meanings of the 8421 indicator codes are shown in Figures 4-5 and 4-6. If
an error occurs during this procedure, the 8421 indicator codes may aid in
locating the cause. Within this form, an On indicator is called a 1, an Off
indicator a 0 (zero).
