Validation Number 10
Review this entire form before starting the procedure to create a backup
load diskette. Unit operating procedures are described in the IBM 3274
Operator's Reference and Problem Determination Guide,
GA27-2850.
This procedure duplicates the existing load diskette.
If you do not get
the expected result in any step, start over at step 1.
If
you still do not get
the expected result, report the problem.
There are four indicators, labeled 8 4 2 1, on the 3274 control panel. The
meanings of the 8 4 2 1 indicator codes are shown in Figures 6-5 and 6-6.
If an error occurs during this procedure, the 8 4 2 1 indicator code may
help you locate the cause. Within this form, an on indicator is called a 1,
an off indicator a 0 (zero). Example: s

2. Ensure that the 3274 Control Unit has power switched on.
Note: When customizing a 3274 Model A, B, or D, do not set the on/off
switch to the off position unless the rotary switch on the control panel
is in the Local/Offline position and the Local/Offline indicator is lit. The
Power/Interface switch must be in the Local/Offline position and the
Local/Offline indicator must be on.
