Connecting Twisted-Pair Cable

Each RJ-45 port on the repeater can accept a standard 8-wire twisted-pair (UTP) cable that ends with an RJ-45 connector. These ports can support cable lengths up to 328 feet (100 meters).

To attach twisted-pair cable, plug one of the RJ-45 connectors into the selected port on the repeater. Connect the other RJ-45 connector into a 100Base-TX or 10Base-T workstation.

Setting the Uplink Switches

The uplink switches enable the 1st and 12th ports on the repeater to function as either standard IN RJ-45 ports or uplinkable OUT RJ-45 ports.

IN ports use an internal crossover of the receive and transmit lines, enabling the port to connect to a network interface card using standard 8-wire UTP cable. OUT ports let you interconnect the repeater and another repeater without the need for special crossover cables and allows the two repeaters to be on the same segment.
