and observe the Link LEDs on the ports. If one of the Link LEDs
periodically blinks, the link may be intermittent. See Problem 8 for
suggestions on possible causes and resolutions.
Problem 8:
A channel 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. Try the following:
❒
Connecting another network device with a different cable to the port. If
the Link LED remains steady on, then the problem is with the original
cable or the network device.
❒
For the AT-MCF2032SP Module, check to be sure that the SFP
module is fully inserted in the slot.
Problem 9:
A channel is operating in the Smart MissingLink mode and the
Link LEDs for both ports are blinking.
Solution:
This can have several possible causes. One possible cause is if
the channel is connected to another media converter that also supports
the Smart MissingLink mode, forming a chain of media converters. What
can happen is if there is a port that cannot establish a link, the Smart
MissingLink mode passes the loss to all of the media converters in the
chain. To identify the source of the problem, set the operating mode on all
of 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 an intermittent link on one of the ports, perhaps
because of a problem with a cable or a network device. To identify which
port has the problem, set the channel to the Link Test mode and go to
Problem 8.
