We have Hurth ZS240 CNC with GE Fanuc 16M with Fanuc alpha drives.
Option board A16B-2200-0931 is suspected to be faulty, please let us know if it can be replaced with A16B-2202-0401 (as this A16B-2202-0401 is also for 16/18 Series), but with this A16B-2202-0401 booting stops at Slot Configuration.
These are absolutely not interchangeable. The A16B-2200-0931 is for FS16M-A and the A16B-2202-0401is for FS16M-B. These are completely incompatible with few parts shared. You may have damaged the A16B-2202-0401 and/or the FS16M-A control.
