Supports 10 or 100Mbps network connections on each RJ-45 port
Magnum DS80 Dual-Speed 10/100 hubs combine two logical hubs -- one at
10 Mbps and one at 100Mbps -- in one physical box supporting two traffic
domains. Each port can operate at either 10 or 100Mbps, independently of the
other ports.

Auto-sensing for speed, 10 or 100Mb on each port
All ports support 10/100 auto-negotiation for speed, operating separately on
each port. Any mix of 10 Mbps and 100Mbps users can be connected to the
ports. Speed-sensing is continuous, occurring at LINK enable. Individual
ports can change to 100Mbps or 10 Mbps speed at any time, adapting to any
changes in the connected device’s speed. Speed-sensing complies with IEEE
802.3u, providing interoperability with other products.

An internal switch connects the 10 and 100Mb domains
Magnum DS80 has an internal switch for filtering/forwarding traffic between
the 10 and 100Mbps domains, allowing all connected devices to communicate
to each other. High performance switching provides full bandwidth in each
domain, unaffected by local traffic on the other domain.

Installation is “Plug and Play”, operation is transparent to software
The Magnum DS80 operates as a hardware switch, only forwarding those
packets from each domain that are needed on the other domain. Internal
address tables are self-learning, enabling users to change port connections or
10/100 domains without affecting operations. The switch in the DS80 will
not affect any standard software applications or SNMP network management
platforms.

Small enclosure enables use in offices and labs
The compact packaging of Magnum DS80s allows them to be installed in
offices and labs, or virtually any location within reach of a standard AC wall
outlet. They come in a durable metal enclosure for table-top or wall-mounting.
They have an external AC to 5VDC power supply. (Models with a 48vdc
external power supply are optionally available).
