The following tables provide an overview of the possible connections for
voltage-carrying lines:
1 Power supply unit 2
a
a. In devices without PoE, power supply unit 2 is optional. It is used for redundant voltage
supply. In devices with PoE, power supply unit 2 is mandatory. It is only used to supply PoE
voltage to the connected devices.
Possible types: C DC voltage connectable
Voltage range:
