StackPower Connector
The Catalyst 3850 switches have a StackPower connector for use with Cisco StackPower cables to
configure a switch power stack that includes up to four switches. A switch power stack can be configured
in redundant or power-sharing mode.
You can order these StackPower cables from your Cisco sales representative:
• CAB-SPWR-30CM (0.3-meter cable)
• CAB-SPWR-150CM (1.5-meter cable)
For details about connecting StackPower cables and StackPower guidelines, see the “Planning a
StackPower Stack” section on page 2-8.
