MAN-POEmax REV1003A
Setup Procedures:
If using a power supply, connect the 48V DC power transformer to the POEmax Power Input connector. Connect
the other end of the power transformer to an AC outlet (Figure 1). The POEmax switch will now operate as PoE
Power Sourcing Equipment (PSE).
If PoE-Powered, then connect a PSE such as another PoE switch or a PoE injector to POE IN Port 8 (Figure 2). The POEmax
switch will now operate as a PoE-Powered Device (PD). POE OUT models can rebroadcast PoE power to other PD’s.
POEmax requires 3 Watts (W) for itself. POE OUT models will split any remaining power among all its PoE ports:
47W with 50W power supply; 97W with 100W power supply; up to 10W when PoE-Powered.
PoE power availability declines over distance. When PoE-Powered, POEmax can rebroadcast 10W PoE power
from 13W PoE input as long as the cable distance from the PSE to the PD (with POEmax somewhere in the
middle) is 50 feet or less. This is enough power to run for example, four iViewHD cameras (2.5W each).

extend Ethernet cable length up to another 100M. POE OUT models can still redistribute any available PoE power.
