3.10.4 Power supply connection
This Ethernet switch has a dual 48VDC-input and must be powered from the PRA-MPS3 to
one of the 48V outputs, normally intended for the amplifiers. Use both A and B outputs for
connection redundancy.
The 48V output that is powering the switch should not be used to also power an amplifier.
The lifeline that belongs to the powering 48V output is not used.
In case of mains failure the switch will be powered from the battery, connected to the
multifunction power supply.
3.10.5 Fault relay connection
The fault relay connection can not be used for UL864/UL2572 systems.
