LMY2-MLAB 3 7 63 1515 0 INSPECTION 2-1. Option card ID Conduct an ID check when power is activated after the card is inserted. 7-segment LED in front of AI8 displays the left digit = (slot number) and right digit = (card type). This will be displayed for 8 slots in sequence, so visually check that it is recognized as LMY2- MLAB.
