This section describes the function and operation of the Magnum P62-Series Switches. 

The Magnum P62-Series Hardened Switch provide six 10/100 RJ-45 switched 

ports, and two 100Mb fiber ports. The architecture supports a dual speed switching environment, 

with two built-in full-duplex “future-proof” fiber ports. The six RJ-45 copper ports equipped with 

auto-negotiation capability.

The switched RJ-45 ports are full / half duplex and auto-sensing for speed. (See section 

2.2). When the connected device is 10 Mbps, P62s obey all the rules of 10 Mbps Ethernet 

configurations. The 10 Mbps users share a 10 Mbps traffic domain, and can “communicate with” 

100Mbps users as well as 100Mbps domain. Similarly, the 100Mbps traffic obeys the rules of 

100Mbps Ethernet, and can communicate with 10Mb domain too. 

All Magnum P62 units are plug-and-play devices.  There is no software configuration to 

be done at installation or for maintenance. The Half / full duplex mode for the RJ-45 switched RJ-

45 ports is user dependent and changes (by auto-negotiation) to full or half duplex as the unit 

attached with these ports. The internal functions of P62-Series Switch is 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 on the same port 

segment will be filtered, constraining them to one port and relieving the rest of the network from 

processing 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.  

Packets needed for maintaining the operation of the network (such as occasional multi-cast 

packets) are forwarded to all ports. 

 

The Magnum P62-Series Hardened Switch 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. 

The Magnum P62-Series units have an address table capacity of 4K node addresses, and 

are suitable for use in large networks. They are self-learning, so that as nodes are added or 

removed or moved from one segment to another, the P62-Series automatically keeps up with node 

locations.
