If the total current consumption of your external devices exceeds the 450mA maximum current
maximum, then use one of the following system configurations:
• Power the panel with an external 12VDC power supply.
• Power some or all of the external devices with an external power supply to lower the
total external current powered by the NetAXS-123 panel below 450mA.
48VDC, and it is measured at the output of the power injector or PoE switch. Line losses cause
a decrease in the power available at the panel when you use longer Ethernet cable lengths. You
can minimize these line losses by using either of the following methods:
• Connecting the NetAXS-123 panel to the power injector or PoE switch with the shortest
possible Ethernet cable length.
• Using a high-power 802.3at power injector or PoE switch with a voltage of 56VDC. This
reduces line losses and thus increases available power at the NetAXS-123 panel.
The NetAXS-123 panel will not benefit from the increased power capabilities of a
