Fast EtherHub 3500 System User’s Guide

Link - The Link LED should light up when a device (e.g., computer, hub or router) establishes a valid connection via the RJ-45 port.

Troubleshooting - If the Link LED does not light up when a device is connected to a 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 use standard, straight-through cables and not crossover or other specialized cables.

Traffic - Refers to the movement of packets received by the port. A port’s Traffic LED will blink in proportion to the rate of traffic passing through the port. It will remain ON during high traffic rates. The network manager can easily determine the activity on a port by viewing this LED.
