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.
The manual power "On-Off" Switch (optional) is used for powering the unit on
and off when it is placed into or taken out of service.
