îš„ Preventing C and D Option Board Connectors from Rising
After installing an option board into slot C or D, insert an option clip to prevent the side with the connector
from rising. The option clip can be easily removed by holding onto the protruding portion of the clip and pull-
ing it out.
Remove the option clip before installing an option board into slot C or D. The option board can not be
installed completely and may not function properly if it is installed with the option clip attached.
