If a LINK LED of a port is lit but there is a communication problem with the port, check the
following:
• Check to be sure that the node connected to the port is operating at 10 Mbps.
• Check to be sure that the duplex setting is set the same on the two nodes
connected to the twisted pair and fiber optic ports of a channel on the media
converter. For example, if the node connected to a twisted air port is set to full-
duplex, then the node connected to its corresponding fiber optic port must also be
set to full-duplex. If necessary change the setting of the HDX/FDX settings of the
interconnected devices.
•
