After upgrading my Matrix, the E-IPA card would not boot correctly

Certain versions of EIPA firmware are only compatible with certain matrix rack codes 

If you find yourself in this position, revert your rack code (CPU firmware) back to the original code and upgrade the EIPA card first, followed by the rack code. 

This should recover your system 


We recommend that all customers upgrade to EIPA v1.69 and CPU code v18.97 as a minimum
