Displayed when the MFB’s main processor fails or is not able to communicate with the Faceplate and Alarm Controller (FAC). The FAC and alarm board processor can still be functioning. In this state, it is safe to remove the DEFINITY LAN Gateway system for repair.
Board Test — Whenever the system is reset, this is displayed when flashware is performing a hardware initialization and test on the MFB.
Displayed when the board test is complete and flashware turns control over to the boot loader.
Operating System Initialization — Displayed just before the boot loader turns control over to the operating system or the booted utility.
Brought up during OS initialization only if the system determines that one or more of the 80386SX, faceplate and alarm controller, or alarm board FPROMs must be reprogrammed.
Reprogramming is done automatically.
WARNING:
The system should never be shut down during the reprogramming sequence. The MFB will have to be sent back to the factory if programming is not allowed to complete.
