Installing the MPA2 Panels
Hardware Specifications
• Power some or all of the external devices with an external
power supply to lower the total external current powered by the
MPA2 panel below 1650 mA.
• The maximum power available in the 802.3at standard is 25.5W. This
limit is generally at 42.5 - 57VDC, 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 MPA2 panel to the power injector or PoE+
switch with the shortest possible Ethernet cable length.
• Amids pan power supply, also known as a PoE power injector, is
an additional PoE power. Class 4 can only be used by IEEE
802.3at (Type 2) devices, requiring valid Class 2 and Mark 2
currents for the power up stages.
