Verifying System Operation

Verify that all attached devices have a valid connection. The hub monitors the link status for each port. If any device is properly connected to the hub and transmitting a link beat signal, the Link LED will light up for the corresponding port. If the Link LED fails to light when you connect a device to the hub, check the following items:

!Be sure all network cables and connectors are properly attached to the connected device and the hub.

!See if your cable is functioning properly by using it for another port and attached device that displays valid indications when connected to the network.

!Verify that you have not exceeded the specified limits for cable length. No twisted-pair cable should exceed 100 meters (328 feet). When attaching a 100 Mbps hub to the repeater ports, only one hub can be cascaded and the maximum length of inter-hub cabling is 5 meters (16 feet). Also note that when using fiber optics, you can run a cable up to two kilometers (1.24 miles) when using full-duplex, or up to 412 meters (0.25 miles) with half- duplex.

!When using an optional uplink module, both sides of the connection must use the same transmission mode (half- or full-duplex). If any device is connected to the 100Base-FX module, then you must manually set the transmission mode using the toggle switch or the configuration options provided by the Agent Module.
