Appendix B. Fiber optic cabling services 251
Under the zSeries Fiber Cabling Services umbrella there are two options to provide individual
fiber optic cables (jumper cables, conversion kits, MCP cables) for connecting to z800, z900,
and z990:
Option 1: Fiber optic jumper cabling package (available today for z800 and z900)
IBM does the detailed planning. This option includes planning, new cables, installation,
and documentation. An analysis of the zSeries channel configuration, I/O devices, and
any existing fiber optic cabling is required to determine the appropriate fiber optic cables.
Option 2: Fiber optic jumper cable migration and reuse for a zSeries upgrade (new option)
This option includes planning, reuse of existing cables, and documentation. IBM organizes
the existing fiber optic cables based upon the new z990 connection details. Relabeling,
rerouting, and reconnection to the appropriate z990 channels is performed. New cables
are not offered as a part of this option.
Summary
Each enterprise fiber cabling services design is unique in that it is based on physical room
characteristics and equipment placement preferences. It is a long-term “connectivity solution”
that provides an organized network of cabling options for future equipment reconfigurations
and additions.
The zSeries fiber cabling services and enterprise fiber cabling services, offered by IBM
Networking Services, are designed to help you keep pace and provide you with the optimum
reliability, availability, and serviceability, as well as the scalability you need to grow your
system(s).
