Magnum DS80F & DS80C Dual-speed Stackable Hubs

Installation and User Guide (12/01)

2.5Features 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.
