Figure 5. StackWise-480 and StackPower Connectors
StackPower can be deployed in either power-sharing mode or redundancy mode. In power-sharing mode, the
power of all the power supplies in the stack is aggregated and distributed among the switches in the stack. In
redundant mode, when the total power budget of the stack is calculated, the wattage of the largest power supply is
not included. That power is held in reserve and used to maintain power to switches and attached devices when
one power supply fails, enabling the network to operate without interruption. Following the failure of one power
supply, the StackPower mode becomes power sharing.
StackPower allows customers to simply add one extra power supply in any switch of the stack and either provide
power redundancy for any of the stack members or simply add more power to the shared pool. StackPower
eliminates the need for an external redundant power system or installation of dual power supplies in all the stack
members. StackPower is available in LAN Base license level (or higher). For LAN Base, cables need to be
purchased separately.
Foundation for Open Network Environment
The heart of the Cisco Catalyst 3850 is the UADP ASIC with programmability for future features and intelligence
with investment protection. The new ASIC provides the foundation for converged APIs across wired and wireless,
Cisco Open Network Environment, software-defined networking (SDN) readiness and OnePK SDK through
software updates over the product lifetime.
