Below are the meanings of the LEDs:
LED Color Description
9.KEY Fixed green GigaKey inserted correctly
Numero di porta (da 1 a 8) Fixed green Power supply on the door
Table 1 – LEDs indications
Power input
The power input technical information is detailed below:
Input voltage Self-consumption Max load
Input 10 – 60V DC < 0.25W per port 180W
Table 2 - voltage range, self-consumption and maximum input load
IMPORTANT NOTE : Each power connector is galvanically isolated from the others.
Special case -48V
The power input does not allow polarity inversion. If you have a voltage of -48V (as often happens in some telecommunications
systems), it is sufficient to connect the 0V cable to the positive (+) terminal and the -48V to the negative (-) terminal according
to the indications of the silkscreen.
Output power
The main function of the PoE injector of this device is to allow the powering of other equipment on the network. 8INJ PoE
injector are passive injectors.
IMPORTANT NOTE : Unlike active PoE, passive PoE does not use any protocol to determine the type of device to be powered;
it simply applies a type of voltage to its port without identifying which type of PoE standard or supply voltage the connected
load is compatible with. Using an unsuitable voltage and / or wrong pin out can cause irreparable damage to the powered
device.
It is possible to power a wide range of devices that accept different voltages as this device essentially replicates the voltage
from the power terminals to the PoE output ports without applying any conversion.
This offers great versatility when it comes to connecting several PoE devices in the same infrastructure as each port can be
powered with a different voltage than the rest.
In addition to supporting different voltages, the 8INJ has the ability to select the pin out of the PoE output ports, with the
GigaKey, thus allowing it to power a wide range of devices on the market.
To find out if your PoE device can be powered via 8INJ, just check the pin out that the GigaKeys allow you to select and see if
it matches the input pin out of your equipment

.
GigaKey
This is the generic name that identifies the output pin out selection keys of each PoE port.
