2.5 Features and Benefits
Supports 10 or 100Mbps network connections on RJ-45 ports # 3 to 8
Magnum DS80F & DS80C Dual-Speed 10/100 hubs combine two logical hubs -- one
at 10Mbps and one at 100Mbps -- in one physical box. Half-duplex ports #3 to 8
operate at either 10 or 100Mbps, independently of the other ports. Any mix of 10Mbps
and 100Mbps users can be connected to the ports. Speed-sensing occurs at LINK
enable and complies with IEEE 802.3u, providing interoperability with other products.
Internal switches connects all of the ports and users
DS80F’s and DS80C’s have internal switches for filtering/forwarding traffic among
the two switched ports (#1SW and #2SW) and the half-duplex 10/100 ports (#3 to 8),
allowing all connected devices to communicate to each other. High performance
switching provides full bandwidth in each domain, unaffected by local traffic on other
domains.
DS80F’s switched fiber-built-in 100Mb port #2, for “backbone” connectivity
The F/H selectable 100Mbps fiber port(2SW) connects to a “future-proof” fiber cable
from the local users upstream to the rest of the network. This is ideal in office
buildings and classrooms where fiber is built into the infrastructure. No media
converter is required. Different fiber connector types and modes are supported by
different models, including 100Mb multi-mode, single-mode, and single-mode long.
Switched RJ-45 N-way port #1 for a high speed “copper” connection
The (1SW) 10/100 switched RJ-45 port #1 can support a local server, a power user,
another hub cascaded, or a switched “stack” connection to another DS80F, DS80C for
expansion. An up-link switch is built in for port #1SW.
Installation is “Plug and Play”, operation is transparent to software
The Magnum DS80F & DS80C operates as a hardware switch, only forwarding those
packets from each domain that are needed on the other domains. Internal address
tables are self-learning, enabling users to change port connections or 10/100 domains
without affecting operations.
Small enclosure enables use in offices, labs and classrooms
The compact packaging of Magnum DS80F & DS80C’s allows them to be installed in
offices and labs, or virtually any workspace location within reach of a standard AC
wall outlet. They come in a durable metal enclosure for table-top or wall-mount. There
is a choice of external power supplies, for either 115vac or 230vac.
