ring topology.
Figure 8-1. Connecting a Stack of Switches
The stack in Figure 8-1 has the following physical connections between the
switches:
• The XG1 port on Unit 1 is connected to the XG2 port on Unit 2.
• The XG1 port on Unit 2 is connected to the XG2 port on Unit 3.
• The XG1 port on Unit 3 is connected to the XG2 port on Unit 1.
PowerConnect 7000 Series and M6348 Stacking Compatibility
The stack can contain any combination of switch models in the
PowerConnect 7000 Series as well as the PowerConnect M6348 switch, as
long as all switches are running the same firmware version.
For example, a single stack of six switches might include the following
members:
• Two PC7048 switches
• One PC7024 switch
• Three PCM6348 switches
Any member can be the stack master.
