ˆThe two network devices are operating in different duplex modes. The media converter performs best when its two network devices and its two ports all use the same duplex mode.

ˆThere could be an intermittent problem with one of the network devices connected to the media converter or with a cable. To determine whether this might be the problem, set the unit to the Link Test mode and observe the Link LEDs of the ports. If one of the Link LEDs periodically blinks, it could mean that the link is intermittent. See Problem 6 for suggestions on how to resolve this issue.

Problem 6: The media converter is operating in the Link Test mode and the Link LED of a port is blinking.

Solution: This could indicate that the link between the port and the network device is intermittent. There might be a problem with the cable or the network device connected to the port. Try connecting another network device with a different cable to the same port on the media converter. If the Link LED remains steady on, then the problem is indeed with the original cable or the network device.

Problem 7: The media converter is operating in the Smart MissingLink mode and the Link LEDs for both ports are blinking.

Solution: This could have several possible causes. This can occur when a port is connected to another media converter that also supports the Smart MissingLink mode, forming a chain of media converters. Media converters that support the Smart MissingLink mode will pass the loss of a link on a port to all the media converters in the chain. This can result in situations where the Link LEDs on both ports of a media converter are blinking, indicating that the source of the problem has its origins in another media converter in the chain. To identify the source of the problem, set the operating mode on all the media converters in the chain to Link Test and then examine the Link LEDs of the ports. The Link LED of the port that cannot establish a link to its network device will be off.

Another possible cause is that a port is only able to form an intermittent link with its network device, perhaps because of a problem with the cable or the network device. To identify which port is having the problem, use the Link Test mode.
