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-45 ports are auto-sensing ports. When inserting a cable into an RJ-45 port, the switch
automatically ascertains the maximum speed (10/100/1000 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).
• Configures the RJ-45 port to enable communications with the attached device, without
requiring user intervention. In this way, the Auto Uplink technology compensates for setting
uplink connections, while eliminating concern about whether to use crossover or straight-
through cables when attaching devices.
