Cisco Catalyst 9300 Series switches are Cisco’s lead stackable enterprise access switching platform and as part of the Catalyst 9000 family, are build to transform your network to handle a hybrid world where the workplace is anywhere, endpoints could be anything, and applications are hosted all over the place.
The Catalyst 9300 Series, including the new Catalyst 9300X models, continues to shape the future with continued innovation that helps you reimagine connections, reinforce security and redefine the experience for your hybrid workforce big and small.
The switch operates with either one or two active power supply modules. A switch that is part of a StackPower stack operates with power that is supplied by other stack switches. Two power supply modules can be powered up from two different phases.
You can use two AC modules or one module and blank cover. All power supply modules have internal fans. All switches ship with a blank cover in the second power supply slot.
