PoE: 822W available PoE with default 1100W AC PSU; additional PSU can increase budget subject to a 1800W platform limit.
PoE Budget Planning
For a Cisco C9300-48U-A 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: 822W available PoE with default 1100W AC PSU; additional PSU can increase budget subject to a 1800W platform limit. 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
- High-density enterprise floors.
- powered access points.
- devices.
- 1G campus access with modular uplink growth.

Selection Guidance |
| Optics and cabling |
Match supported transceivers and fiber or copper cabling to modular 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. 822W available PoE with default 1100W AC PSU; additional PSU can increase budget subject to a 1800W platform limit. |

Key Difference |
| Cisco C9300-48P-A |
48 x 1G copper; modular uplink |
PoE+ |
Same Catalyst 48-port access family and Advantage tier; UPOE supports higher-power endpoints. |
| Huawei S5735-S48P4X |
48 x 1G copper, 4 x 10G SFP+ |
PoE+ |
Similar 48-port campus access, but PoE+ is a lower per-port power class than Cisco UPOE. |
| Arista CCS-720XP-48TXH-2C-S |
48 x 100M-10G copper, 4 x 25G SFP28, 2 x 100G QSFP |
Up to 90W per port |
Higher-speed powered campus access; compare PSU capacity against the C9300-48U-A budget. |
