Installation and User Guide (04/01)

Rear port(s) may be used for additional user(s).

Stackable Personal Hubs

Stackable Personal

Hubs may also be used as a

stand-alone network for a personal multi-user system such as shown below. Up to eight RJ-45 user ports are

available where only 10BASE-T wiring is used, and full-length Ethernet segments are

supported on all ports. In this application, the Up-Link switch is in the straight-through or “==” position so that port 8 is a user port, not an up-link to another hub.

When network requirements exceed the capacity of a single ST80, additional hubs may be stacked to form a single logical hub. This stacking capability allows one to build larger networks that are in compliance with the “four repeater rule” specified in the Ethernet standards. As with a single ST80 unit, a stack may be connected to a backbone through any standard Ethernet media. A stack of ST80s may also be cascaded as a unit into another stack or hub.
