Magnum H80B and H80P Personal Hubs  User Guide (07/95)

GARRETT

9

The H80P's small size makes it very useful for situations

where a temporary twisted pair network is needed, and only AUI

ports are available.  It is handy as a piece of test equipment that can

be easily inserted into an AUI backbone to provide a test port, and

then removed after the testing is done.   The H80P Personal Hub

takes up minimal space, uses minimal power, and is rugged enough

to be carried in a coat pocket for possible emergencies.
