CFF RAID adapter
Use the section to understand the power cable and signal input cable routing for CFF RAID adapters.
Cable routing for CFF RAID adapters
For the locations of connectors on CFF RAID adapters and the processor board, see RAID and HBA adapter connectors and Processor-board connectors for cable routing for details.
For more information about the CFF RAID adapters supported, see RAID adapter.
The table below presents that how the power cables and MB input cables are connected with one and two processors installed. Find more connections in different configuration at Cable routing for backplane signals (one processor) and Cable routing for backplane signals (two processors).
