8INJ MANUAL VER. 2 REV. 0
The GigaKey has been designed to avoid manipulating the microswitches or jumpers which usually satisfy this function but
are subject to errors. This simplifies the selection, which can be done simply by inserting the chosen key into the slot
corresponding to the PoE port.
If desired, you can select a different key for each PoE port on the same unit.
At the moment 4 different GigaKeys have been developed that allow a wide range of compatibility between the devices on the
market. They are easy to identify through their code and different colors.

Table 3 – Pin out GigaKey keys
(*) These are just some of the devices that can be powered by 8INJ. The list is very long, if you want to know if your equipment can be connected to 8INJ, please do
not hesitate to contact us.
Pay attention to the direction of insertion of the GigaKeys in the slots: the correct position is with the screen printing facing
upwards.
ATTENTION : in case of incorrect insertion of the GigaKey, the device will still supply power to the port, but with an
unpredictable pinout. This can cause damage to connected devices.
Special case -48V
There are installations that require -48V power supply via the network, this option is perfectly feasible with 8INJ. We simply
have to connect -48V to the 8INJ
4
input and then choose the correct GigaKey in order to get -48V on the PoE ports based on
the input pin out of the devices we want to connect.
Protection
On each port there are double phase surge arresters TVS (Transient Voltage Suppression) and GDT (Gas Discharge Tube).
