The above provided information enables a managed station( a PC or Console 
terminal) to connect directly to the switch using a straight through cable.(Note: 
The Null-Modem (DB-9) cable is optional and can be order from the factory, 
along with the unit 
 

NOTE for Power Substations:   In support of the IEEE 1613 Class 2 standard, GCI 

advises that, for substation applications, the serial RJ-45console  ports are 
intended for temporary connectivity to other equipment such as PCs.  Since the 
console port connection is temporary, it is excluded from IEEE 1613 packet-
loss testing per the 1613 standard-defined test procedure.  

 
 
4.0 OPERATION 

This chapter describes the functions and operation of  the Magnum 6K25 

Switch. 

A Magnum 6K25 provides switched connectivity at Ethernet wire-speed 

among all of its ports.  The Magnum 6K25 supports10/100Mbs for copper media and 10 

or 100Mb separate traffic domains for fiber ports to maximize bandwidth utilization and 

network performance.  All ports can communicate to all other ports in a Magnum 6K25, 

but local traffic on a port will not consume any of the bandwidth on any other port. 

Magnum 6K25 units are plug-and-play devices.  There is no software 

configuring necessary to be done for basic operation at installation or for maintenance. 

The only hardware configuration settings are user options for an UP-LINK Switch 

(resides inside the unit) on the 6K8-RJ45. Optional Half / Full duplex mode and 10 or 

100Mbps selection for the switched ports must be configured through MNS software per 

unit as per the requirement. The internal functions of both are described below. 

Each time a packet arrives on one of the switched ports, the decision is taken to 

either filter or to forward the packet.  Packets whose source and destination addresses are 

on the same port segment will be filtered, constraining them to that one port and relieving 

the rest of the network from having to process them. A packet whose destination address 

is on another port segment will be forwarded to the appropriate port, and will not be sent 

to the other ports where it is not needed. Traffic needed for maintaining the operation of 

the network (such as occasional multi-cast packets) are forwarded to all ports. 

 

The Magnum 6K25 Switches operate in the store-and-forward switching mode, 

which eliminates bad packets and enables peak performance to be achieved when there is 

heavy traffic on the network.
