Helios IP Verso can be powered either from an external 12 V / 2 A DC source or
directly from the LAN equipped with PoE 802.3af supporting network elements. Owing
to different power outputs, the power supply selection affects the maximum count and
applicability of the modules connected of the basic unit.
