That was not the issue: the real issue was the thermal expansion and contraction of the connectors causing the connectors to loosen over time. We are talking about connectors that passed a kilowatt at 450 MHz heating up, then cooling off suddenly as they were near or within the cool air-conditioned stream from the rack's environmental systems.

Thanks for the detailed rundown, Steve. Very interesting. And, of course, the difference between CCS and ICAS is always a factor.
