2.7 Applications
Example 1 : A Magnum DS880-B serves a small office with mixed speed requirements. Some
users operate at 100Mb, and some users and utility devices (such as print servers) run at 10Mb.
All share the same hub, and talk to each other via the bridge module inside. Any node can
change speed at any time without affecting network operation or impacting other users.

Example 2 : Where there are existing 10Mb hubs and users, they can easily be cascaded into
any port of the DS880-B. This allows simple plug-and-play addition of 100Mb ports to an
existing 10Mb network without having to change it. Nodes that are capable of 100Mb speed can
be moved to any DS880 dual-speed port, and will automatically operate at the higher speed.
The dual-speed ports on the DS880-B can be used for adding 100Mb users or for
accommodating existing high performance users. The 100Mb traffic does not use the bandwidth
of the 10Mb domain, so overall performance of the network is improved.
