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 switch. This		Switch
		SUPPL
allows the Switch to operate only	A+	+ FUS
	A-	-
whenever DC power is correctly applied

to the two inputs. It protects the Switch	GND	CHASSIS
		GND

from incorrect DC input connections. An incorrect polarity connection, for example, will neither affect the switch or its internal power supply. Nor will it blow the fuse in the internal power supply.

B3.0 APPLICATIONS FOR DC

POWERED ETHERNET SWITCHES

Magnum 6K8-Series Switches are

easily installed in a variety of applications where -48VDC, 24, or 125VDC or 5VDC power is used as the primary power source. The DC power configuration capability provides

an Ethernet networking solution utilizing a special power supply in switches with a proven track record.
