The following table describes the system LED designations.

Device Hardware Interfaces

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, or 1000 Mbps) and duplex mode (half-

duplex 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.

2 SFP Ports - 1 LED per

port

SFP LINK/ACT • Solid Green - A valid 1000 Mbps SFP
