14 Planning for CRU Replacement
When you replace a CRU online, you must prepare all elements in the system that are
affected by the removal of that CRU, such as other CRUs and processes. Use the
procedure in this section and worksheets to determine which components of a system
are affected by removal of a PMF CRU, SEB, or MSEB.
To replace a PMF CRU, SEB, or MSEB, you must use a guided replacement tool which
automatically detects the affected components and prepares the system for CRU
replacement. See the Service Management Packages on page 1-35 for guided
replacement tools which contain online help topics.
For more information about the pathways, see ServerNet Communication Pathways on
page 6-1.
ServerNet Communication Pathways
Worksheets
The ServerNet communication pathways worksheets help you trace the ServerNet
communication pathways in your system so that you can determine which components
and enclosures would be affected by the removal of a PMF CRU, SEB, or MSEB.
Copy the appropriate worksheets from Appendix C, Blank Forms.
