| + | =====Summary===== |
| + | Passive PoE: Simplifies power delivery by providing a fixed voltage but lacks safety and negotiation features of Active PoE. |
| + | Correct Usage: Ensure voltage and device compatibility, use proper wiring, and stick to low power devices. |
| + | Incorrect Usage: Avoid mismatched voltages, incompatible devices, overloading, and improper wiring to prevent damage and ensure reliable operation. |
| + | Using Passive PoE appropriately can be cost-effective and straightforward, but it requires careful consideration of device requirements and proper installation practices to avoid potential risks. |
