Hi Rich,
That's true. Those components are going to fail sooner or later and need to
be replaced.

Can you tell me please what module I need to order and maybe where I can get
it? I don't want to throw a whole card away only because of ONE broken port.

We have deployed a lot of those modules and I need to to get them replaced.
The problem is that I need the GIGEs on the managementcard because all other
slots are full so I need to get them fixed.

I can't mix jetcore and ironcore but the M4s you were mentioning are an
option. Are you absolutely sure that they are not affected by this problem?
