IBM DS4700 manual Controller a Controller B Host Ports

Note: The alignment of the single-ported host channels on controller A are opposite those of controller B. Before inserting an SFP module into a host port, verify that the SFP module is rotated correctly to match the alignment of the host port on the RAID controller. Do not force-fit.

2.Connect the fibre channel cables from the SFP modules in the DS4700 Express RAID controller host ports to either the SFP modules in the fibre channel switch or the SFP modules of the host bus adapters. Figure 83 and Figure 84 show the location on the RAID controllers on models 70 and 72 of the DS4700 Express Storage Subsystem where the host-system cables connect.
