Using LC-LC fibre-channel cables
The LC-LC fibre-channel cable is a fiber-optic cable that you use to connect
DS4700 Express fibre channel ports into one of the following devices:
v An SFP module installed in a fibre channel switch port
v An SFP module of the host bus adapter port
v An SFP module installed in an IBM DS4000 storage expansion enclosure
See Figure 38 on page 62 for an illustration of the LC-LC fibre-channel cable.
For more information about cabling these devices, see the documentation that
comes with the LC-LC fibre-channel cable.
