With the exception of the dual DC input power connections and the power supply, all 

specifications and configuration options for the Magnum DS8016-48VDC with this Dual-
Source option are identical to those listed in the Magnum DS8016 Dual-Speed Hubs 
Installation and User Guide, including Appendix A “Optional 48VDC Power”  
  
C2.0 

 

The hub models with the internal 48VDC Dual-Source power supply are designed 

for installations where a battery plant is the power source, and where two separate power 

sources are utilized in order to increase operational uptime and to simplify maintenance.   

The functionality of the Magnum DS8016-48VDC Dual-Source Option hubs are 

identical to the standard AC-powered models.  All Port Module, SNMP and stacking options 

are available for configuration with Dual-Source Option units.  Refer to the main sections of 

this Installation and User Guide for a detailed description of the Magnum DS8016 Hubs. 

 

The Dual-Source DC power option is designed using diodes inside of the hub on 

each DC power input line.  A diode is placed 

in each of the four input lines (behind the 

four external power connection terminals) so 

that power from an external source can only 

flow into the hub.  This allows the hub to 

operate whenever DC power is correctly 

applied to either or both of the two inputs.
