1. Magnum 500 Series units are plug and play devices There is no software configuring to be done at installation or for maintenance The only hardware configuration settings are user options for UP LINK on 10Mb port 8 and the Half Full duplex mode selection for the 100Mb ports of the Magnum 528 and 528F 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 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 Traffic needed for maintaining the operation of the network such as occasional multi cast packets are forwarded to all ports The Magnum 500 Series Switching Hubs 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 500 Series units have large address table capacity of 1 9K node addresses 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 500s automatically keep up with node2. Ethernet ports operation is certain regardless of whether the attached device does or does not properly support auto negotiation This is desirable when there are unknown devices presently or potentially connected which may or may not operate correctly at all times with auto negotiation In some applications it may be desired to use standard auto negotiation and or to configure the first 1OOMb copper port for up link For trained technicians there are internal switches and jumper settings that allow these choices to be made as described in GARRETT 18 Magnum 500 Series Switching Hubs Installation and User Guide 08 98 Figure 3 5 Be certain that the main power is off before opening the unit or changing any internal settings Switch Port Function Default setting Manual setting Both 100Mb 100 Mb Non Auto AUTO Uplink _X When Non Auto Jumper __ Port Function Position1 2_ Position 2 3 JP4 Pot 1 10 100 config 100 Mb default 10 100 contig 100 Mb default 10 Mb SW7 JP4 JP3 SW2 100Mb PORTS NEGOTIATION UPLINK X PA M M Figure 3 5 Magnum 528 s internal jumpers for auto negotiation ON or OFF Note that auto negotiation is an on going process that can introduce changes in network operation at any time whether intended or accidental Getting an auto negotiating network running properly once is not enough to make certain that it will continue to operate corr

22. e traffic load is greatest To minimize the possibility of dropping frames on congested ports the Magnum 500 Series dynamically allocates buffer space from a 1 MB memory pool ensuring that heavily used ports receive very large buffer space for packet storage Many other switching hubs have their packet buffer storage space divided evenly across all ports resulting in a small fixed number of packets to be stored per port When the port buffer fills up dropped packets result This dynamic buffer allocation provides the capability for the maximum resources of the Magnum 500 unit to be applied to all traffic loads even when the traffic activity is unbalanced across the ports Since the traffic on an operating network is constantly varying in packet density per port and in aggregate density the Magnum 500 Switches are constantly adapting internally to provide maximum network performance with the least dropped packets Another feature implemented in Magnum 500 series switches is a collision based flow control mechanism When the switch detects that its free buffer queue space is low the switch prevents more frames from entering by forcing a collision on all receiving half duplex ports in order to stop incoming traffic See Section 4 6 for additional details The latency the time the frame spends in the switch before it is sent along or forwarded to its destination of the 500 Series switches varies with the port speed types and the length of the
