FAQs
What is passive PoE and how does the POE4818G work?
Passive PoE delivers power directly over Ethernet pins without the overhead of standard PoE protocols. The POE4818G injects 48V power into the Ethernet cable, allowing compatible devices to receive both data and power through a single connection.
Which devices are compatible with this PoE injector?
The POE4818G is compatible with devices designed to accept 48V passive PoE power, such as certain wireless access points, IP cameras, and other network devices. Check your device's specifications to confirm compatibility before purchasing.
Do I need to configure the POE4818G before use?
No. The POE4818G is plug-and-play and requires no configuration. It automatically detects the power requirements of connected devices and supplies the appropriate power level.
Can I use this adapter with standard PoE (802.3af/at) devices?
The POE4818G provides 48V passive PoE, which is different from standard PoE protocols (802.3af/at). It is not compatible with standard PoE devices. Ensure your device supports 48V passive PoE before use.
What is the maximum cable distance for PoE power delivery?
Passive PoE power delivery quality degrades over distance. For optimal performance, keep cable runs as short as practical, typically under 100 metres. Consult your device manufacturer's specifications for exact requirements.
Is the POE4818G suitable for outdoor installation?
The POE4818G features a wall-mount design suitable for many indoor environments. For outdoor use, confirm that it is protected from weather and meets your environmental conditions. Refer to the product datasheet for temperature and humidity ratings.
What warranty does TP-Link provide?
The POE4818G is covered by a 36-month (3-year) manufacturer warranty from TP-Link, providing protection against defects and failures during normal use.
