Re: ISE5 appliance
Given the question, it has to be a 5-2 as that is the only machine the problem exists with.
As far as I are aware there are two boards that are NLA as the company that made them no longer exists, they went about two years or so ago leaving a number of people in the cart as it were. That’s why there is little to no chance of sourcing a replacement.
You get this from time to time with spare parts and there’s not much anyone can do about it, especially where it is very specific components used.
