ROM checksum failure service error code
The operator panel button has been pushed and a ROM checksum
failure service error has occurred.
Once the error code is displayed, if the operator panel button is
pushed again, the operator panel displays the service error
indication (all six indicator lights blinking). Continual pressing of the
operator panel button causes the lights to repeat in the following
order:
1. Service error indication
2. ROM checksum failure service error code indication
3. Service error indication
Replace the ROM SIMM. If this does not correct the problem,
replace the controller card.
