To all the users out there with M-series I/O from the last century, what has been your philosophy / choices regarding replacement? Since our system dates to a time before any I/O card redundancy was available, how concerned should we be about cards that have been under power for 18 years? We have had (knock on wood) scarcely any outright hardware failures, but as we plan it would be interesting to hear other's views on hardware longevity . . .
- Do you get early signs of trouble (random errors) or do cards just give it up completely and suddenly one day?
- Any tests to reveal "weak" components?
- Failure modes? Are there particular components (e.g. capacitors) on cards that are destined to be the "first to go"?
I recently cycled power on a few dozen "Series 2" H1 cards as a result of flashing them to SW revision 4.9; since then (about a year ago) we've had a couple that went offline - restored by reseating the card.
