Stacking PowerConnect 10G Switches
Many Dell PowerConnect™ switches include a stacking feature that allows multiple switches to operate as a single unit. Starting with firmware 4.2, the latest PowerConnect 10 Gigabit switches can now be stacked. These stacks can include up to six 8024/8024F switches or up to six M8024-k switches. Appendix A at the end of this document shows the maximum scalability, stacking six 8024F switches using eight stack ports between each member.
A single switch in the stack (known as the Master switch) manages all the units in the stack and uses a single IP address, which allows the user to manage every port in the stack from this one address. This IP address is copied from the Master to the Standby when the Standby is created. If for any reason the Master fails and the Standby takes over as the Master, the IP address of the stack will remain the same, allowing continuous management of the stack.
