Cisco Catalyst 9200 Series switches support dual field-replaceable power supplies. Each switch ships with one default power supply, and a second identical power supply can be purchased with the initial order or can be added at a later time. The second power supply can provide redundancy or additional power to PoE+ ports as needed.
