FTA2 Fan Module not working

[cerickson111]

I have a known good fan module that does not work when plugged into a 15454 Cerent chassis.  Any ideas on where to check first?  Pin-out of the connector on the back of the shelf possibly?

its already eos, so the rma would not be possible from tac. but you check it once for clarity.

Thank you.     I found a spare daughter board that is wired to the fan module connector, and replacing it fixed the trouble.
