Traffic

SuperSmart User’s Guide

TROUBLESHOOTING If the Link/Traffic LED does not light up when a device is connected to its corresponding port, check that both the hub and connected device are powered on. For devices connected to the hub using a twisted-pair cable, check that the cable length does not exceed 100 meters. You should have standard, straight cables and not cross-over or other specialized cables.

Traffic refers to the movement of packets being received by the port. A port’s corresponding Link/Traffic LED will blink (ON) in proportion to the rate of traffic passing through the port.

Through this LED, the network manager can easily view the activity on a port.
