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.

LED Designation

Power LED • Off - Power is disconnected.

• Solid Green - Power is supplied to the switch and is operating

normally.

FAN LED • Off - FAN is operating normally.
