3.7 Cascading Personal Hubs with the Up-Link Port
Personal Hubs may be cascaded in order to expand
networks. For example, any Personal Hub may be cascaded via the
switchable up-link port into any port of another hub. Since each
Personal Hub provides full repeater functionality, cascaded units can
operate together even though there may be a full segment of distance
between them.
Based on the "four repeater rule" defined by Ethernet
standards, there may normally be a maximum of four units in any one
chain between any two users.
Magnum Personal Hubs may also be cascaded in networks
with other Magnum Hubs (such as Magnum Workgroup Hubs and
Magnum 3000 Stackable Hubs and Concentrators) as well as with
Ethernet hubs from other manufacturers.
