Resiliency and high availability • StackWise-1T: Cisco Catalyst 9300 Series modular uplink models (C9300X SKUs) support the industry’s highest back-panel stacking bandwidth solution (1 Tbps) with StackWise-1T. Up to eight switches can be configured in a StackWise-1T with the special connector at the back of the switch, using dedicated stack cables. • StackWise-480: Cisco Catalyst 9300 Series modular uplink models (C9300 SKUs) support a high-speed back- panel stacking bandwidth solution (480 Gbps) with StackWise-480. Up to eight switches can be configured in a StackWise-480 with the special connector at the back of the switch, using dedicated stack cables. • StackWise-320: Cisco Catalyst 9300 Series fixed uplink models (C9300L and C9300LM SKUs) support a stacking bandwidth solution (320 Gbps) with StackWise-320. Up to eight switches can be optionally configured in a StackWise-320 with the special stack kit at the back of the switch, using dedicated stack cables. • Cisco StackPower: Cisco StackPower is an innovative power interconnect system that allows the power supplies in a stack to be shared as a common resource among all the switches. This allows you 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. Up to four switches can be configured in a StackPower stack with the special connector at the back of the switch. However, with the use of the XPS-2200 appliance, up to eight switches can be configured in the StackPower stack. Cisco StackPower is supported only on the models with a modular uplink stack - C9300 and C9300X SKUs. Catalyst 9300X models support StackPower+, delivering more power over StackPower cables compared to the Catalyst 9300 models. Figure 7.
