Dell Networking N4000 series switches can be stacked with Dell Networking PC8100 series switches with the entire stack required to run 6.0.0.8 or later firmware (6.1.0.1). Dell Networking PC8100 series switches can support both 5.x and 6.x firmware versions, but Dell Networking N4000 can support only 6.0.0.8 and later firmware versions (6.1.0.1).

An important advantage of stacking is that it provides a consolidated interface for management of multiple switches that are linked together. One switch acts as the Master through which the entire stack is managed through various interfaces (Web, CLI, and SNMP). After a stack is deployed in the network, operators can easily add units to the stack as their port requirements increase, with minimal administrative overhead
