Overview
The Cisco C9300X-48HX-E is designed for high-density multigigabit campus access. It combines 48 x 100M/1/2.5/5/10G copper with Cisco UPOE+ up to 90W per port with modular c9300x uplink slot; module ordered separately. Wi-Fi 6/6E access layers, powered building devices, and 10G copper aggregation at dense enterprise sites.
Choose this configuration when the access, aggregation or core design calls for the port media and software shown below. Confirm optical modules, power budget and licenses against the final bill of materials.

PoE: 590W available PoE with default 1100W AC PSU; optional 1900W PSU increases budget to 1390W before secondary PSU options.
PoE Budget Planning
For a Cisco C9300X-48HX-E deployment, multiply each powered device's datasheet maximum input by its quantity, then add a 25% planning reserve (not an IEEE requirement). Compare that total with the available PoE budget: 590W available PoE with default 1100W AC PSU; optional 1900W PSU increases budget to 1390W before secondary PSU options. Check each device against its port's IEEE PoE power limit and the available powered-port count; the per-port rating does not mean every port can supply that maximum at once. Calculate your project PoE budget before selecting power-supply options. The result is a planning estimate, not a compatibility guarantee.
Use Cases & Deployment Scenarios
- Wi-Fi 6/6E access layers.
- powered building devices.
- 10G copper aggregation at dense enterprise sites.
Recommended Accessories

Selection Guidance |
| Optics and cabling |
Match supported transceivers and fiber or copper cabling to modular c9300x uplink slot; module ordered separately. |
| Uplink module |
Choose a compatible uplink module separately; the slot alone does not add ports. |
| Power supply |
Size PSU capacity against endpoint draw. 590W available PoE with default 1100W AC PSU; optional 1900W PSU increases budget to 1390W before secondary PSU options. |
