Power for your Network: The 4-Port Gigabit PoE+ Injector
Your switch doesn't have PoE ports, but you want to operate modern IP Cameras, WiFi Access Points or VoIP phones? No problem! The Extralink 4-Port Gigabit PoE Injector is the smart and cost-effective solution. Instead of upgrading your entire Network, this compact powerhouse specifically feeds power into up to four existing Ethernet lines. You simply connect it between your normal switch and the end devices – done. This way, you can retrofit your Network with PoE without having to dig deep into your pockets.
Flexible and Powerful: PoE according to 802.3at/af Standard
This injector is not just a simple power source; it's an intelligent partner for your devices. Thanks to support for IEEE 802.3af (PoE) and the significantly more powerful 802.3at (PoE+) standard, it is extremely versatile. It can power simple devices with up to 15.4 watts, but also operate power-hungry PTZ cameras or modern Access Points with up to 30.8 watts per port. You determine the actual power yourself by choosing your external Power Supply (not included) – a flexibility that gives you full control over your setup.
Plug-and-Play: Installation is that simple
Forget complicated configurations or driver installations. The Extralink Injector works on the plug-and-play principle and is OS-independent. Installation is completed in three simple steps: Connect the four 'LAN' ports to your router or switch. Connect your PoE-enabled end devices to the four 'PoE' ports. Finally, connect your separately purchased Power Supply to the injector. The LED indicator confirms the correct power status, and your devices are online and powered. It hardly gets any easier if you want to buy a Gigabit PoE+ Adapter and get started immediately.
Robust Design for Professional Use
The first impression is not deceiving: The robust metal housing is designed for long-lasting and reliable continuous use. With its compact dimensions, the injector fits anywhere and can also be neatly installed on a wall or in a technical cabinet thanks to the provided mounting holes. The extended operating temperature range of -10 °C to 60 °C ensures that it reliably performs its Service even under demanding environmental conditions. An ideal solution for professional installations of IP Cameras and other devices from the category PoE Injectors / Power Supplies.

Frequently Asked Questions (FAQ)
Do I need a special power supply for this PoE Injector?
Yes, you need an external DC power supply, which is not included. The voltage should be between 12V and 57V, and the total power (in watts) must be sufficient to power all connected devices. A common voltage for 802.3at devices is 48V to 56V.
Can I also connect non-PoE devices to this unit?
Yes, that is safe. Since this is an 'active' PoE Injector, it checks whether the connected device supports the PoE standard before supplying power. If it does not detect a PoE-enabled device, it only forwards the data and does not apply power to the line.
What does 'Mode B' mean for this injector?
'Mode B' (also called Midspan) describes which wire pairs in the Ethernet Cable are used for power transmission. In Gigabit Ethernet, all four pairs are used for data. Mode B applies power to pairs 4/5 (positive pole) and 7/8 (negative pole), which also transmit data simultaneously. This is a common standard for injectors.
Can I use the four PoE ports for four high-performance PTZ cameras?
Yes, provided your external power supply is strong enough. Each camera requires up to 30 watts according to the 802.3at standard. For four cameras, you therefore need a power supply with at least 120 watts (4 x 30W) of power to fully utilize all ports simultaneously.
Is the installation complicated?
No, the installation is very simple (Plug-and-Play). Connect the 'LAN' ports to your existing switch, the 'PoE' ports to your end devices (e.g., cameras), and finally connect the power supply to the injector. No configuration is necessary.
Does this injector also support the new PoE++ (802.3bt) standard?
No, this model exclusively supports the PoE (802.3af) and PoE+ (802.3at) standards. For devices requiring more than 30 watts (e.g., high-end cameras or thin clients), an injector with 802.3bt support (PoE++) is required.
