2.2.2 Magnum H80P Product Description
Magnum H80P Personal Hubs provide a simple and
inexpensive solution for expanding a single AUI port into an eight
port hub. Since the H80P receives power through its DTE (male
AUI) port, it may be installed in virtually any location, without
worrying about access to a power outlet. To the server, router or
other device to which it is connected, the Magnum H80P appears as
a standard transceiver. The rear DTE port of the unit allows for
direct drop cable connection to any AUI port.
As an option, the H80P may be powered by an external
power suppy (see Spare Part Ordering information, Section 1.3).
When used for redundancy, the external supply retains local
connectivity in the event of a power outage on the AUI segment. In
addition, the external power supply allows the H80P to function as a
standalone unit.
NOTE: Since the Magnum H80P receives its power from
the rear DTE port, this port must be connected to the AUI
port of another Ethernet device to allow the H80P to
operate, unless the opitonal external power supply is used.
