Hello The FX630 is a 13th generation server. We have recently started selling 14th generation servers. I don't think we have released a 14th generation of the FX series yet. Our naming conventions have changed over the years, and they sometimes differ across product lines. FX, 6, 3, 0FX: denotes rack, tower, or some other form factor.(R630, T630, FX630)6: denotes classification of system specs/configuration possibility. 1 is entry level and 9 is top of the line.3: denotes generation. 4 is 14th, 3 is 13th, 2 is 12th, 1 is 11th, etc0: is usually used to denote a differentiation is nearly identical model names. For instance, if there is an AMD and Intel version of the same model the Intel would be 0 and the AMD would be 5. Thanks
I am a little new to Dell, I having a problem identifying the FX series Servers. I am currently trouble shooting a Windows Server OS problem, and all of the support documentation is always pointing to a Power Edge Server Generation, and how to read it from the first letter, number etc. However I cannot make sense of how the FX630 are read to identify the generation of the Server?
