Power Consumption: Same as for AC models (see Section 1.1)

With the exception of the power supply, all specifications and functions of Magnum 6K25e 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.

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 SWITCHES

Magnum 6K25e Fiber Switches are easily installed in a variety of applications where -48VDC, 24VDC and 125VDC power is used as the primary power source. The- 48VDC, 24VDC and 125VDC power configuration provides an Ethernet networking solution utilizing a special power supply in a managed Fiber Switch.

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
