Device Hardware Interfaces This section provides information for the following hardware interfaces: • RJ-45 Ports • SFP GBIC Module • Factory Defaults Button RJ-45 Ports RJ-45ports are auto-sensing ports. When inserting a cable into an RJ-45 port, the switch automatically ascertains the maximum speed (10 or 100 or 1000 Mbps) and duplex mode (half- or full-duplex) of the attached device. All ports support only Unshielded Twisted-Pair (UTP) cable terminated with an 8-pin RJ-45 plug. To simplify the procedure for attaching devices, all RJ-45 ports support Auto Uplink. This technology allows attaching devices to the RJ-45 ports with either straight-through or crossover cables. When inserting a cable into the switch's RJ-45 port, the switch automatically: • Senses whether the cable is a straight-through or crossover cable. • Determines whether the link to the attached device requires a "normal" connection (such as when connecting the port to a PC) or an "uplink" connection (such as when connecting the port to a router, switch, or hub).
