Easy-to-Use: A working stack is self-managing and self-configuring. When switches are added or removed, the master switch automatically loads the CISCO IOS® Software revision running on the stack to the new switch, loads the global configuration parameters, and updates all the routing tables to reflect changes. Upgrades are applied universally and simultaneously to all members of the stack.
Low Operations Cost: In the event of an outage, you can remove a troubled switch from an existing stack of switches and replace it with another switch. Then, the master switch will recognize this as a maintenance outage and automatically reload the port-level configuration that was on the previous switch without user intervention. This allows IT managers to have local personnel in remote locations perform maintenance tasks instead of sending costly technicians out for a few minutes of work—saving thousands of dollars in operational costs.
Mix and Match Switch Types: Create stacks with any combination of Cisco Catalyst 3750 and 3750-E switches. Customers who need a mixture of ports, PoE, and wiring-closet aggregation capability can incrementally develop the access environment, paying only for what they need. When uplink capacity needs increasing, you can easily upgrade your bandwidth by adding a 10 Gigabit Ethernet version to the stack and upgrade your Gigabit Ethernet links with 10 Gigabit Ethernet to the existing fiber.
