X7-8 Director Hardware Installation Guide
•
A minimum of four ICL ports (two on each core blade) must be connected between each chassis pair.
•
The dual connections on each core blade must reside within the same ICL trunk boundary on the core blades.
•
If more than four ICL connections are required between a pair of chassis, additional ICL connections should be added
in pairs, with each additional pair residing within the same trunk boundary.
•
QSFP-based ICLs and traditional ISLs are not concurrently supported between any pair of chassis.
•
Gen 6 QSFPs (4x32G QSFPs) must be used on Gen 7 ICL ports to connect to a Gen 6 or Gen 5 chassis through an
ICL port for connections up to 100m.
•
Gen 6 QSFPs (4x32G 2-km QSFPs) must be used on Gen 7 ICL ports to connect to a Gen 6 chassis through an ICL
port for connections up to 2 km. 16G 2-km QSFPs are not supported on Gen 7 ICL ports.
The X7 Director can be connected in a core-edge configuration. The following figure shows two core devices and four
edge devices. Although X6 Directors are shown in the figure, the same principles apply to X7 Directors. 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.
