LED Activity Condition Indication

STEADY LIGHT ON Indicates a valid link has been established on this port.

Troubleshooting

If the Link LED does not light up when a device is connected to its corre-

sponding port, check that both the hub and connected device are powered on. For devices

connected to the hub using twisted-pair cable, check that the cable length does not exceed

100 meters. You should have standard, straight-through cables and not crossover or other

specialized cables.
