Example 2 : Magnum 528

The Magnum 528 Switching Hub is a Magnum 508 plus two 100Mb Fast Ethernet RJ-45 ports. The applications may be similar to the Magnum 508 but, but with two 100Mb copper ports, it also provides switched connectivity between 10Mb and 100Mb network segments.

Consider Figure 2.4c. In this example, a small corporation reached a point where it needed to make a decision about adding some 100Mb servers and users to the existing 10Mb network. The servers had installed 10/100 network interface (NIC) cards and, as one application alternative, they may be connected to the Magnum 528’s 100Mb ports to provide much better 100Mb server access speed for all the 10Mb users.

As the network expands further, some users may need to go to 100Mb speed. To accommodate this while maintaining the rest of the network topology, a 100Mb hub may be attached to one of the Magnum 528’s Fast Ethernet port (see illustration in Figure 2.4c below, showing only one server per 100Mb port). The Fast Ethernet hub (for example, a Magnum Lite ML8 100Mb office hub) then provides 100Mb ports for the servers and for some 100Mb users.

The Magnum 528 Switching Hub provides complete network connectivity so that all 10Mb and 100Mb nodes operate in a unified manner, functioning as one plug- and-play switched network facility.

In this example, the 10Mb segments on the 528’s 10Mb ports each have 10Mb of switched bandwidth, and may be either half- or full-duplex per port. Simultaneously, the two Fast Ethernet ports provide 100Mb F/H each, and have full-speed switched access to each other as well as to each of the 10Mb ports.
