🔍 Main Description
Type: Passive PoE Injector / Passive PoE Adapter
Model: RP023-2400500ZG
Function: Combines electrical power and network data onto one Ethernet cable, eliminating the need for a separate power line to the remote device.
⚙️ Key Specifications
PoE Type: Passive Power over Ethernet — fixed 24 V DC feed (does not negotiate power like standard 802.3af/at PoE).
Output Voltage: 24 V DC
Output Current: 0.5 A
Max Power: ~12 W
Ethernet Speed: Gigabit (1× 10/100/1000 Mbps) pass-through — carries both data and power.
Ports:
• 1 × LAN/Data-in (Ethernet)
• 1 × Data + PoE-out (Ethernet with power)
Power Cord: Usually not included.
📡 Typical Use Cases
This adapter is typically used to power outdoor or remote networking devices such as wireless bridges and access points that require 24 V passive PoE power — especially models from Ruijie/Reyee like:
Because it does not support standard PoE negotiation (802.3af/at), you should only use it with compatible devices to avoid damage.
📍 What “Passive PoE” Means
Unlike standard IEEE PoE standards (802.3af/at), passive PoE:
Supplies constant DC power (24 V) over Ethernet pairs
Doesn’t negotiate power levels with the connected device
Must be used with devices designed for that voltage/power type
