To connect multiple switches via ICLs, a minimum of four ICL ports (two on each
core routing blade) must be connected between each chassis. The dual connections
on each core blade must reside within the same trunk group. If more than four ICL
connections are required between a pair of switches, additional ICL connections
should be added in pairs (one on each core blade). ICLs and ISLs are not
concurrently supported between a single pair of switches.
The switch can be connected in a core-edge configuration. The following figure
shows two core and four edge devices. Although SAN512B-6 switches are shown
in the figure, the device can be either SAN256B-6 or SAN512B-6 switches. The
cabling scheme should follow the parallel example shown in the previous figure.
Each line in the example actually represents four cables running between the
devices.
