Magnum 6K8-Series Industrial Field Switch Installation and User Guide (04/07)

Magnum 6K8-Series 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.

Filtering and Forwarding

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 un-

interrupted operation of the network (such as occasional multi-cast packets) is forwarded

to all ports.

The Magnum 6K8-Series 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.

Address Learning

All Magnum 6K8-Series units have address table capacities of 4K node

addresses suitable for use in larger networks. They are self-learning, so as nodes are

added, removed or moved from one segment to another, the 6K8-Series Switch

automatically keeps up with node locations.

An address-aging algorithm causes least-used addresses to fall out in favor of

frequently used addresses. To reset the address buffer, cycle power down-and-up.
