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 provide either
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.

The Cisco Catalyst 3750-X Series and 3560-X Series Switches support four optional network modules for uplink
ports. The default switch configuration doesn’t include the uplink module; at the time of switch purchase the
customer has the flexibility to choose from the network modules described in Table 3.
