Repeat for each cable that you are installing.
If you are installing ICL cables for the first time, pay particular attention to the
configuration in which the cables must be installed. See “Possible ICL
configurations” for one possible configuration between two chassis.
4. Replace the chassis door (“Removing and installing the chassis door” on page

5. Once all the cables are attached, see the Fabric OS Administrator’s Guide for the
configuration procedure.
Possible ICL configurations
The following figure illustrates one possible QSFP cable configuration between two
SAN384B-2 or SAN768B-2 chassis. Up to five neighboring chassis can be connected
as long as each of two cores in one chassis is interconnected with each of two cores
in the next chassis. This provides for inter-chassis link (ICL) trunking between
chassis, ensuring redundancy. Parallel connections between core blades are
recommended, but both parallel and mesh cable arrangements are supported.
