2.2 Product Description
The Magnum H80B and H80P Personal Hubs are nine-port
workplace hubs in a very compact package. They are simple to
install and use in an office or lab environment, requiring no special
rack cabinets or wiring closet apparatus. Personal Hubs are standard
physical layer Ethernet products and operate independently of all
software.
Personal Hubs fit easily into the workplace environment.
They are versatile enough to be table-top or shelf-mounted.
Alternatively, a Velcro  strip is included in the package so that the
unit may easily be installed on a wall surface, or on the back or side
of a desk or cabinet. All of the wiring connectors are in the same
plane so that wiring space is neat and minimal. The external power
supply unit (optional for the H80P) conveniently plugs into an AC
wall receptacle or power strip.
The H80B and H80P Personal Hubs' RJ-45 ports support
connection of up eight workstations or other network devices over
full length 10BASE-T cable segments. Personal Hubs operate in
compliance with the IEEE 802.3 specification for repeater
functionality to perform signal amplification, re-timing of data
packets, and regeneration of preamble bits for each packet received.
