Why use Stack Ethernet Switches?

 
Why use Stack Ethernet Switches? Stacking Ethernet switches lowers the network administrator's total cost of ownership. The cost of maintaining the network is decreased because there are many devices to manage, and the network uptime is increased with built-in redundancy.  Flexibility of Cisco Flex Stack technology  offer modular stacking capability. Cisco Catalyst 2960-S switches can be added to a stack at any time by adding the optional Flex Stack module. As with the increase in networking the demand for Ethernet access ports increases, Cisco Catalyst 2960-S switches can be stacked together either to create a new stack or to add new Cisco Catalyst 2960-S switches to an existing stack.
