Next, connect the Director devices to the Virtual Chassis. In general, you want to
accomplish the following:
• Connect three ports from one network module in a Director device to the first Virtual
Chassis, and three ports from the second network module to the second Virtual Chassis.
You need to repeat these connections from the second Director device to both Virtual
Chassis to provide resiliency for the system.
• Connect the Director devices to each other and create a Director group. You can use
either straight-through RJ-45 patch cables or crossover cables, because the Director
devices contain autosensing modules. Connect one port from each network module
on the first Director device to one port in each network module on the second Director
device.
Figure 78 on page 290 shows the specific ports on the Director group that you must connect
to the Virtual Chassis and interconnect between the Director devices.
