IBM 3745 Series Service Functions page 12

Summary of Changes
The following changes have been made in this book:
• The panels related to the CCU display in the CDF (Chapter 9) have been
modified to account for a new CCU type.
• The concurrent maintenance (CACM) function has been modified in Chapter
10. Shutdown (SHT) and restore (RST) commands are now the only allowed
commands in service mode.
• The functions related to the Ethernet** adapter have been added. The main
impact is on Chapters 4 (TSS Functions) and 9 (CDF Functions), and to a
lesser extent Chapters
3
(Diagnostics) and
12
(Miscellaneous Functions).
Note: Some panels have been modified to add the new adapter in the pro-
cedures. Depending on the microcode level of your machine, some
panels may slightly differ from those described but this does not
affect the procedures.
• The layout of the book has been modified to make the procedures easier.
• Quick information retrieval helps have been added at the beginning of the
chapters covering complex functions. They consist mainly in Road Maps,
and synoptics. Road Maps are dual-entry tables telling you where to go
according to what you want to do and the part of the
3745
you are working
on.
