Magnum DS50 DS60s Dual Speed Hubs Installation and User Guide 06 02 2 4 Features and Benefits E Supports 10 or 100Mbps network connections on each of six RJ 45 ports A Magnum DS50 DS60 Dual Speed hub combines two logical hubs one at 10Mbps and one at 100Mbps in one physical box supporting two traffic domains Each port can operate at either 10 or 100Mbps independently of the other ports E Future Proof Fiber Switched port for DS60F model only The Magnum DS60F model equipped with one Switched fiber port at 1OOMb enables it to provide secure longer cable distances and eliminates the use of a media converter The fiber port is available in SC multi mode single mode and Long reach E Plug and Play Installation and Operation The DS50 DS60 Dual speed Hub Plus learns the network addresses of both network segments from the packets in the traffic so there is no software set up required As nodes are added or changed the unit learns the new network addresses and adapts its filtering and forwarding of packets automatically E Segments 100Mb networks for high performance and simplified expansion The Magnum DS60 s only provides a separate collision domain which maximizes available bandwidth for both of the attached segments enhancing network performance The segmentation of the switched port 6 also resets cable distance limitations and repeater hop counts to enable easy expansion of 10 100Mb nets E User configu

28. e permits collision fragment frames which are a result of late collisions to be forwarded to add to the network traffic Since there is no way to filter frames with a bad CRC the entire frame must be present in order for CRC to be calculated the result of indiscriminate cut through forwarding is greater traffic congestion especially at peak activity Since collisions and bad packets are more likely when traffic is heavy the result of store and forward operation is that more bandwidth is available for good packets when the traffic load is greatest To minimize the possibility of dropping frames on congested ports Magnum DS60 s Switched port dynamically allocates buffer space from an 1MB memory pool ensuring that heavily used ports receive very large buffer space for packet storage Many other switches 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 to the DS60 s 6 port 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 DS60 s Switched 6 port is constantly adapting internally to provide maximum network performance with the least dropped pac
