Update-Diskette Installation Procedure for Configuration
Support A, B, or C
This procedure uses the update-diskette package and current diskettes to
incorporate maintenance enhancements into 3274 Control Units that have
been previously customized with Configuration Support A, B, or C. Contact
the person responsible for customizing your 327 4 before you perform this
procedure. It should take you less than 1 hour to complete this procedure.

Obtain the following:
a. Current system diskette (primary or backup), language diskette (if
applicable), and RPQ diskette(s) (if applicable)
b. New system diskette
c. New feature diskette
d. All RPQ diskettes, if any, included in the update package. If a
diskette.is included for a new RPQ, place it with the other RPQ
diskettes. If a new RPQ diskette is provided for an existing RPQ,
substitute it for the current RPQ diskette.
Note: Do not install this update unless (1) the configuration support (A, B,
or C) on the new system diskette is exactly the same as that shown on your
current system diskette, and (2) the release number on the new system
diskette is higher than the release number on your current system diskette.
2. Ensure that the 327 4 has power on.

not press the IML pushbutton.
(If
you do press the IML pushbutton, go
back to step 3.) In approximately20 seconds, the 8 4 2 1 indicators will
display a flashing 1110 code.
