Posted 16 Mar 2019 Hello! I have 1746-A10 ser.A faulty chassis. Can I replace it by 1746-A10 ser.B? I think Yes, but I can be wrong ) Share this post Link to post Share on other sites
Posted 17 Mar 2019 Yes. The very oldest Series A chassis had some MOV's under the processor slot that were notorious for getting bent and damaged, and Series B improved that design. 1746 chassis of any Series are 100% compatible with all controllers, modules, and power supplies.
