Has anyone else had intermittent problems with a single row on a 34932A failing to respond to code and/or front panel commands? When it starts to occur it does not report any error but will fail to open or close until power is cycled on the 34980 chassis. I should clarify, it seems to accept the open or close command, it just fails to physically change the contacts. I have seen this on at least 3 different 34980/34932 chassis. I am doing firmware upgrades now to try to solve it, but I do not see anything about it in the firmware history so I don't hold a lot of hope for it solving the problem.
