Device Hardware Interfaces

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, 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.
2/4-SFP Ports - One LED/
Port SFP Link/ACT LED •Solid Green - A valid 1000Mbps SFP
module link is established on the port.
•Flashing Green - Packets transmission or
reception is occurring on the port at
1000Mbps.
•Solid Yellow - A valid 100Mbps SFP
module link is established on the port.
•Flashing Yellow - Packets transmission or
reception is occurring on the port at
100Mbps.
•Off - No SPD link is established on the port.
