Indication

Indicates a valid link has been established on this port.

Indicates the port is receiving packets; blinking is proportional to the traffic passing through the port. No valid link has been established on this port.

Link

The corresponding LINK/TRAFFIC LED should light up when a device (e.g., computer, hub or bridge) establishes a valid connection using the RJ-45 port. However, for the ALT PORT, no link connection is tested. The LINK/TRAFFIC LED for ALT only monitors the traffic condition.

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 an STP or UTP 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

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.
