3. Remove the protective cap from the fibre channel port. Save the protective cap
for future use.
4. Insert the SFP module into the fibre channel port until it clicks into place. See
Figure 26.
Note: The alignment of the fibre channel ports on controller A are opposite
those of controller B. Before inserting an SFP module into a port, verify
that the SFP module is rotated correctly to match the alignment of the
port on the RAID controller. Do not force-fit. For fibre channel ports in
controller A, SFPs should be inserted with the exposed printed circuit
facing up (as shown in Figure 26). For fibre channel ports in controller B,
SFPs should be inserted with the exposed printed circuit facing down.
5. Connect a fibre channel cable.
