3.10Cascading the ST80 Personal Hub with the Up-Link port

Stackable Personal Hubs may be cascaded in order to expand existing networks. For example, an ST80 may be cascaded via the switchable up-link port into any port of another hub. Also, Stackable Personal Hubs may be connected to a backbone via the rear AUI port. With the addition of a mini-transceiver, the AUI port may be used to connect to any standard Ethernet media. (ST80-B and ST80-F Personal Hubs may connect directly to 10BASE2 and multi-mode Fiber, respectively.) Since each ST80 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 be a maximum of four units in any one chain between any two users. Note that a stack of ST80s is a single “unit” for repeater functionality.

Magnum ST80 hubs may also be cascaded in networks with other Magnum Hubs (such as Magnum Personal Hubs, Magnum 1000 Workgroup Hubs, and Magnum 3000 Stackable Hubs and Concentrators) as well as with Ethernet hubs from other manufacturers.
