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.
B3.0 APPLICATIONS FOR DC POWERED ETHERNET SWITCHES
Magnum 6K16-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.
The –48VDC solution is particularly useful in the telecommunication industry,
where it is common for facilities to operate on -48VDC power. Such companies include
regular and wireless telephone service providers, Internet Service Providers (ISPs) and
other communication companies. In addition, many high availability equipment services,
such as broadcasters, publishers, newspaper operations, brokerage firms and other
facilities often use a battery backup system to maintain operations in the event of a power
failure. It is also frequently used for computer system backup, management and
operations monitoring equipment.
The 24V and 125VDC options are particularly useful in the Industrial environment,
where it is common for facilities to operate on 24VDC or 125VDC power. The 125VDC
