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.
