Catalyst 9300 48-Port PoE+ Switch

The Cisco Catalyst 9300 is a rack-mountable, managed enterprise switch delivering 48 Gigabit Ethernet ports with PoE+ support. It runs the Network Advantage licence tier and supports stacking for simplified operations. The platform is built on an x86 architecture to host containers and third-party applications directly on the device.

Suits SD-Access cores and high-density access layers

Network teams deploying Cisco Software-Defined Access will use this switch as a foundational building block. Its 480 Gbps stacking bandwidth handles heavy aggregation traffic. Organisations needing multi-gigabit or fibre downlink ports on every interface should evaluate other Catalyst models that provide those speeds.

48 PoE+ copper ports with stacking uplinks

The primary specification is the 48-port 10/100/1000Base-T configuration with Power over Ethernet Plus on every port. Uplink connectivity is provided through dedicated stacking ports rather than fixed modular slots. Buyers must confirm the Network Advantage licence matches their feature requirements before purchase.

Questions about this item

What maintenance or replacement will the power supply need later?

The switch uses a power supply as its power source; replacement units are available when the original reaches end of life.

What limit shows up first under sustained PoE+ load across all 48 ports?

The total PoE+ power budget of the installed power supply caps simultaneous full-power delivery to every port.

How much heat and noise does the 1.7-inch rack unit produce when running all day?

The compact 1.7-inch chassis uses internal fans to move air front-to-back; acoustic output and exhaust temperature rise with PoE load and ambient temperature.
