The RJ-45 ports auto-sense the connection speed, which can be either 10Mbps or 100Mbps without user’s intervention. The 10Mbps or 100Mbps connection will send the traffic to the corresponding internal segment, while traffic transverse within device running at different speeds automatically switched to the other segment. The uplink switching port is used to extend the node to node distance between two hubs up to 300 meter without the 205 meter limitation mentioned in Fast Ethernet Class II Repeater standard. Moreover, more than two hubs could be cascaded through uplink ports rather than two hubs only in Fast Ethernet hubs. Each dual-speed hub build-in an embedded switch module so it is really plug and play and do not worry about the communication between 10Mbps and 100Mbps segments within the same hub. Meanwhile, the optional slide-in module on the back allow the dual-speed hub connect to the 100BaseFX media type. The dual-speed hub has been designed to conform to the IEEE standard for Local Area Networks, and provides all the standard function of 10BaseT, 100Base-TX and 100Base-FX repeater, including: Signal retiming, Preamble regeneration, Fragment extension, Automatic partition/reconnection Key Features ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦
