=====Correct Way=====
#Voltage Matching: Ensure that the voltage supplied by the Passive PoE injector matches the voltage required by the device.
#Voltage Matching: Ensure that the voltage supplied by the Passive PoE injector matches the voltage required by the device.
#Device Compatibility: Use Passive PoE with devices specifically designed to accept the supplied voltage without power negotiation.

=====Incorrect Way=====
#Mismatched Voltage: Connecting a device to a Passive PoE injector that supplies a higher voltage than the device is designed for, leading to potential damage.
#Mismatched Voltage: Connecting a device to a Passive PoE injector that supplies a higher voltage than the device is designed for, leading to potential damage.
#Incompatible Devices: Using Passive PoE with devices that require IEEE 802.3af/at/bt compliant power negotiation, which can lead to malfunction or damage.
#Incompatible Devices: Using Passive PoE with devices that require IEEE 802.3af/at/bt compliant power negotiation, which can lead to malfunction or damage.
#Overloading: Attempting to power devices that require more power than what the Passive PoE can provide, causing inadequate performance or device failure.

=====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.
