Magnum 6K25 Managed Fiber Switch

Installation and User Guide (04/06)

Input Voltage: 36 - 70 VDC

 

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

Power Supply (Internal 24 VDC Option) Industrial Applications DC Power Connector: 3 terminals: -“, “GND”, “+” Input Voltage: 20 - 36 VDC

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

Power Supply (Internal 125 VDC Option) Industrial Applications DC Power Connector: 3 terminals: -“, “GND”, “+” Input Voltage: 88 - 150 VDC

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

With the exception of the power supply, all specifications and functions of Magnum 6K25 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 6K25 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 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.
