Phase C Overvolts The voltage on phase C is above the maximum value for the CEM3 Check the incoming power supply to the rack
Rack Memory Error The CEM3 is unable to communicate with the memory chip on the backplane Check the CEM3 is seated correctly; Replace backplane
Rack Detect Error The CEM3 is unable to detect the rack type from the DIP switches on the backplane Check the CEM3 is seated correctly; Replace the backplane
Fan Fail The CEM3 detects that the rack fan is drawing current outside the expected value Check the rack fan and fan fuse.
Config Rejected A config was loaded that contained invalid data or values Re-generate configuration; contact ETC
AF Card Error 1 The CEM3 is unable to communicate with AF card 1 Check the AF cards and CEM3 are seated correctly; Check rack hardware for damage
AF Card Error 2 The CEM3 is unable to communicate with AF card 2 Check the AF cards and CEM3 are seated correctly; Check rack hardware for damage
AF Card Error 3 The CEM3 is unable to communicate with AF card 3 Check the AF cards and CEM3 are seated correctly; Check rack hardware for damage
AF Card Error 4 The CEM3 is unable to communicate with AF card 4 Check the AF cards and CEM3 are seated correctly; Check rack hardware for damage
