PoE Availability and Power Requirements
PoE Availability is a switch's total power, in Watts, that it can distribute among all connected clients. Your PoE Availability must be greater than the sum of all device power requirements to prevent instability or failure.
| Switch Model | PoE Availability |
|
Lite |
45-52W |
|
Standard |
42-195W |
|
Professional |
120-600W |
|
Pro Max |
180-720W |
|
Enterprise |
120-720W |
| Enterprise Campus | 950-1,050W |

PoE Adapters
A PoE Adapter can be used as an alternative power source if you do not have a PoE switch. It can also be used to offload connected devices after you’ve exceeded your switch’s PoE Availability.
