input in the primary line.
If the indicator is on, the outputs of the primary and the
secondary lines are normal.
If the indicator is on, the output in the primary line is
abnormal, for example, less than the undervoltage value
(30 V DC to 34 V DC) or greater than the overvoltage
value (78 V DC to 80 V DC).
The secondary power output is abnormal because of the
power fan fault, overheated power module, or lightning
prevention circuit fault.
Table A-18 shows the indicators of the AC-input power module.
