Two previous messages are on point - use other cables to make sure it is not 
the cable, try other ports and unplug everything else from the switch.

I recently had an entire switch fail and had to replace it. At the beginning of 
troubleshooting I told my wife “it’s likely not the switch, they never fail”, 
it of course was indeed the switch that completely failed.

So if you do all of the above and still have issues, it is likely the switch!

Hope this helps,

A little help please!

I normally connect my Anan 7000 transceiver to an eight port switch where it 
connects with the computer that controls the transceiver. It has worked 
perfectly for months. But  I am now seeing error messages indicating short 
intermittent sequence errors (dropped packets I suppose you would call it) 
between the radio and the computer. As you would expect, the audio drops out 
when the errors occur.

First step in my process of elimination was to circomvent the switch and 
connect the radio directly to the computer. That killed all sequence errors and 
all worked as it should. Next step in the process was to reconnect the computer 
and the radio to the switch, but remove the ethernet surge protector from the 
run between the switch and the radio. That made no difference and the errors 
resumed. Now I figure it's got to be bad ethernet cable or the switch needs to 
be replaced.

Any thoughts on this from my computer savvy ham friends?
