This figure shows error codes (fail codes) correlated to all possible card failures in order of probability. To convert the card number to actual
I
board/card socket location, see Figure A-12 (FO-3, FO-5) or Figure 1-7. If codes 0101,0110, and 0111 are alternating, use the flashing code
as the failure indicator.

AL T 1 IML can be performed, the operational code was
properly loaded from the diskette. This eliminates the
diskette, cables, motor rotation. fuses, and voltage as
possible causes.

Go to MAP A20 if card-swapping did not fix problem or if not all
cards are available.
Check for proper diskette.

Go to MAP A40 if problem still exists.

Check for loose card in socket Y6. Go to MAP A50.
Go to MAP A50.

Go to MAP A90 (Model 51 Conly).
The customer security administrator must reload the master key
after the card is removed and replaced. This procedure and the
associated encrypt/decrypt information are contained in Chapter 6.
The 3274 does not have the required storage. Verify storage cards.
See Figure 2-4. Verify Customization Response 113. Occurs for
Configuration Support 0 and above.
Incorrect system diskette or load diskette for Model 51 hardware.
Verify system diskette or load diskette. Occurs for Configuration
Support 0 and above.
The 3274 control storage does not match customization response
113. Occurs when performing an AL T-1 operation. Verify that
storage cards are correct. See Figure 2-4.
Change diskette drive file control card (card No. 22) and system
diskette.

If the board has been replaced, verify that board wiring has been
properly modified. See Figure 4-14.
Uncustomized system diskette.
Operational code failed to load correctly. Try spare system diskette.
