Port Connections, Cables, and Pinout Information This section explains the device's physical interfaces, and provides information about port connections. Connector types, ports and cables are summarized in Ports, Connectors, and Cables. Copper Cable and Optical Transceiver Diagnostics are supported. RJ-45 Connections for 10/100/1000BaseT Ports The 10/100/1000BaseT ports are copper twisted-pair ports. To establish a link for the twisted-pair ports, Tx pair on one cable end must be connected to the Rx pair on the other cable end, and vice versa. If the cabling is done such that Tx on one end is wired to Tx on the other end, and Rx is wired to Rx, a link is not established. 36 Installing the PowerConnect Device
