With the exception of the power supply, all specifications and
functions of Magnum 6K32T Switch -48VDC, 24VDC and 125VDC models are
identical to those listed in the main manual.
B2.0 -48VDC, 24VDC and 125VDC POWER, THEORY OF OPERATION
The -48VDC, 24VDC and 125VDC power options are designed using diodes
inside on each DC power input line behind the two external power connection terminals,
so that the power from an external
source can only flow into the hub.
This allows the Switch to operate
only whenever DC power is
correctly applied to the two inputs.
It protects the Switch from incorrect DC input connections. An incorrect polarity
connection, for example, will neither affect the Switch, its internal power supply, nor will
it blow the fuse in the internal power supply.
