Genelec 4430A Quick Setup Manual page 3

Example of powering the 4430A with a PoE+ enabled IP switch. With this
method, the power budget available for all outputs connected to the IP switch
must enable each 4430A to run at full PoE+ power. For 4 loudspeakers, the
power supply must support 4 x PoE+ power level.
Example of powering the 4430A with a PoE+ power injector. This method
enables the use of standard non-PoE IP switches. Each power injector must
support full PoE+ power level into the device.
The 4430A supports automatic negotiation with the IP switch or IP power injector
to set the PoE power level. However, in some cases it may be necessary to set
the PoE power level in the switch manually.
