The Cisco Catalyst 9300 Series switches are the next generation of enterprise-class stackable access-layer switches that are part of the Catalyst 9000 switching family. These switches support full PoE+, Cisco UPOE, and field-replaceable redundant fans and power supplies. In addition, Cisco Catalyst 9300 Series models also support a variety of fixed and modular uplink options for both copper and fiber uplink support as well as dense 1GE fiber connectivity for FTTX and 1GE aggregation.
