Magnum 1000 Workgroup Hubs Installation and User Guide (04/02)

B3.0 APPLICATIONS

Magnum 1000 Workgroup Hubs are easily installed in a variety of applications where -48VDC, 24VDC & 125VDC power is used as the primary power source. The -48VDC, 24VDC & 125VDC power configuration provides an Ethernet networking solution utilizing a special DC internal power supply in hubs having a proven reliability record.

The 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), other communication companies, and firms supplying network management and operations monitoring equipment. In addition, many high-availability equipment services, such as in broadcasters, publishers, heavy industrial plants, brokerage firms and others, often use a battery backup system to maintain operations in the event of a power failure.

The 24VDC & 125VDC solution are particularly useful in the Industrial environment, where it is common facilities to operate on 24VDC & 125VDC power. The 125VDC solution is mainly used in Utilities Industries, such as Electric substation, Electrical generating plant etc. Whereas 24VDC application is mainly in the Industrial environment, such as chemical plants, paper mill, stone quarrying plant, wastewater treatment Plant etc

B4.0 INSTALLATION

This section describes the installation of the -48VDC, 24VDC &125VDC power source leads to the -48VDC, 24VDC & 125VDC power terminal block on the

Magnum 1000’s. (see figure below).

Block on Magnum 1000’s-48VDC

The -48VDC, 24VDC & 125VDC terminal block on the Magnum 1000’s is located on the rear of the unit and is equipped with three

(3) screw-down lead posts. The leads

are identified as negative (-), positive (+), and chassis ground (GND). The connection procedure is straightforward. Simply connect the DC leads to the Switch’s power terminals, positive (+) and negative (-) screws. The use of Ground (GND) is optional; it connects to the Switch chassis. Ensure that each lead is securely tightened.
