Cisco StackPower: Efficient Use of Power
Source: Cisco Systems
The benefits of the Cisco StackPower technology are immediately tangible, and so are the savings. Consider a stack of switches with each switch requiring a slightly higher power budget for some extra Power over Ethernet (PoE) devices randomly scattered in the stack. Purchasing extra second power supply for each switch that needs some additional power would be inefficient and expensive. With the Cisco StackPower solution, a common pool of power is made available and additional power can be automatically redirected to the appropriate switch based on the available power budget in the common power pool.
