Depending on when you purchased your Oracle Fabric Interconnect, your chassis contains either an FP-1 or an FP-2:
The FP-1 has long release levers that attach to a threaded standoff near the bottom of the mounting bracket's face
The FP-2 has short release levers that attach to a threaded standoff near the top of the mounting bracket's face.
New mounting brackets are required to accept the FP-2. The mounting brackets have two threaded standoff whereas the old mounting brackets have only one threaded standoff.
Because the new mounting brackets are required to accept the FP-2, you will need to completely unrack, then rerack the Oracle Fabric Interconnect to replace the old mounting brackets with the new ones.
As part of unracking the Oracle Fabric Interconnect, you will need to uncable the system and remove facility power. Consequently, you will need to schedule a service window to accommodate a service interruption.
Before beginning this procedure, make a note of how all the cables are connected for the Fabric Board and I/O modules to facilitate returning the Oracle Fabric Interconnect to service.
