The power supply unit types have the following different properties:
Type of connections: terminal or plugged
Type of connectable supply voltages: DC or AC voltage
Level of connectable supply voltages:
Note:
To find out which power supply unit type your device has, refer to items
36 and 37 of the product code (see
table 5
on
page
26).
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.
