TP-Link 8-port Gigabit managed reverse PoE-switch

The TP-Link Managed Switch TL-RP108GE is an 8-port gigabit switch with integrated reverse (passive) PoE functionality. Seven RJ-45 Gigabit PoE input ports accept power from PoE injectors, while Port 8 provides a PoE output. A dedicated DC output supports selectable 5 V or 12 V for powering devices such as ONTs. Combining data switching and PoE in one compact unit reduces cabling and the need for additional power outlets, simplifying deployment of PoE-capable equipment.

Advantages

The switch provides eight gigabit Ethernet ports with a switching capacity of 16 Gbit/s and a MAC address table that supports efficient traffic handling. Integrated reverse PoE input ports allow the unit to receive power from external injectors, and the dedicated PoE output and DC output enable direct powering of customer-premises equipment. Managed switching features and support for common IEEE networking standards ensure compatibility with existing networks while maintaining a compact, black metal design for rack or wall installation.

Suitable for

• Supplying power to CPEs and ONTs in small ISP or branch deployments
• Expanding gigabit LANs where PoE-capable devices must be powered without extra outlets
• Managed network segments requiring VLANs, traffic control and compatibility with IEEE 802.3 standards

How to use

Install the TL-RP108GE in a suitable location and connect up to seven PoE injectors to the PoE input ports to feed power into the switch. Connect network devices to the remaining Gigabit ports as required. Use Port 8 to supply PoE power to a CPE or similar device. If a device requires DC power, use the DC output and select the appropriate voltage (5 V or 12 V) before connecting. Configure managed features through the switch management interface according to your network policies.

Recommendations

Ensure PoE injectors and powered devices are compatible with passive reverse PoE and observe the power budget limits of connected devices. Place the switch in a ventilated location, follow grounding and installation guidelines, and update firmware to maintain stability and security.
