The figure shows a data stack of switches that provides full bandwidth and redundant StackWise cable connections. Figure 4: Example of a Data Stack with Full Bandwidth Connections This figure shows an example of a stack of switches with incomplete StackWise cabling connections.
  • Page 6 Installing a Switch Power-On Sequence for Switch Stacks Figure 7: Example of a Partitioned Data Stack with a Failover Condition Power-On Sequence for Switch Stacks Consider these guidelines before you power on the switches in a stack: • The sequence in which the switches are first powered on might affect the switch that becomes the stack master.

  • Page 7: Planning A Stackpower Stack

    Before connecting the switches in a power stack, read the following guidelines: • C9300 and C9300X switches support Cisco StackPower providing up to 1000 W of power in nominal conditions and 2400 W of power in failure conditions across a power stack. Cisco StackPower is not supported in C9300L switches.

    Installing a Switch Installing the Switch Figure 11: Example of a StackPower Stack with a Failover Condition In the following figure, StackPower port B on the center switch has failed and the stack partitions into two stacks. The top two switches share power, and the bottom switch is now a separate stack. After initial failure of cable 2, any further failure of a port is considered a double fault, which a StackPower cannot handle.
