This probably sounds really dumb but I am completely new to this. I inherited a couple of CS1G's with a bunch of IO modules and a 10 way backplane from a piece of equipment that was scrapped. I got the CPU talking after days of fiddling around with the serial cable, I have an ID291 installed but I have to get some kind of OP module going to get any further. I've got an OD218 and an ID217 as well but when I try to install either with CXOne they are not in the listings. How do I deal with this type of install? Thanks
