The port connections between the Summit switches and the Summit Virtual Chassis
shown in Figure 8 are as follows:
• Port 17 on Switch A is cabled to port 1 on Chassis 1.
• Port 18 on Switch A is cabled to port 1 on Chassis 2.
• Port 49 on Switch B is cabled to port 2 on Chassis 1.
• Port 50 on Switch B is cabled to port 2 on Chassis 2.
Summit switch connections must be cabled to the same port numbers on both
Summit Virtual Chassis. If not, communication among the switches will not
operate properly.
