Error Log Entries and Test to Clear Values
Notes:
a. Error type 1 indicates SNC on-board microcontroller error. (This occurs
whenever the microcontroller sanity test fails, the ROM has problems, the
processor internal or external RAM is faulty, or the firmware instruction test
fails. In addition, this error indicates problems with the interrupt
capabilities, the dual-port RAM and the RTM (real-time monitor) interface
on the faceplate of the SNC.)
Replace the SNC circuit pack.
b. This error indicates that the SNC circuit pack has been busied out via the
busyout board UCSS command. To resolve this error, release the SNC
circuit pack via the release board UCSS command.
c. These errors occur whenever firmware detects failure of the phase-locked
loop, inability to lock, or failure of the clock drivers and the problem is
off-board.
1. Enter display errors and if SNC-BD error type 1793 exists in the
hardware error log, follow the associated repair procedures for
SNC-BD error 1793.
2. Enter display errors and if no SNI-BD 1025 errors exist in the error
log, replace the active SNC.
