Interpreting the Main Control Card
Power-Up Error Codes
The error codes listed in Table 3 may appear on the Main Control Card
numeric display during startup.
NOTE: 1. A normal running system may show other codes (card diagnostics or errors).
However, during start-up, only the codes in this table are possible. Any other
code shown during start-up indicates a faulty Main Control Card.
2. Codes possible AFTER start-up include card diagnostics codes (last card lo-
cation tested - top number indicates bay number, bottom number indicates
card slot number). Maintenance logs give results of test, pass or fail with
cause.
