Gigabit PoE+ Injector 30W

This compact injector adds Power over Ethernet to a standard Gigabit link. It accepts a non-PoE input and supplies up to 30W to a connected device. The unit complies with IEEE 802.3af and 802.3at standards. No configuration is required for operation.

Installers needing single-device PoE power

Technicians running one wireless access point, IP camera or VoIP phone will find this injector a simple, cost-effective solution. It is not suited for deployments that require multiple powered ports or centralised power management. Buyers who need to power several devices from one unit should consider a multi-port PoE switch instead.

30W maximum power output

The injector delivers up to 30W to IEEE 802.3at PoE+ devices and remains backward compatible with 15.4W 802.3af equipment. Auto-sensing technology adjusts the supplied power to match the connected device. This single rating determines whether the injector can support the intended endpoint.

Questions about this item

How much space do the two Gigabit Ethernet ports and the power connection need on a shelf or wall mount?

The injector has one Gigabit Ethernet input and one PoE+ Gigabit Ethernet output plus an AC power inlet, so allow room for three cables and the compact housing

What is the correct order to connect the injector so the auto-sensing 30 W PoE+ activates properly?

Plug the AC power cord into the injector first, then connect the non-PoE switch to the data-in port, and finally attach the PoE device to the PoE-out port

Will the internal power supply or the PoE circuitry need replacement after a certain period of use?

The unit is a sealed solid-state injector with no fan or user-serviceable parts; it is designed to run continuously without scheduled component replacement
