Attention: To avoid breaking the retaining clips or damaging the VRM connectors, open and close the clips gently. 7. Turn the VRM so that the VRM keys align correctly with the slot. 8. Insert the VRM into the connector by aligning the edges of the VRM with the slots at the ends of the VRM connector. Firmly press the VRM straight down into the connector by applying pressure on both ends of the VRM simultaneously. The retaining clips snap into the locked position when the VRM is firmly seated in the connector. If there is a gap between the VRM and the retaining clips, the VRM has not been correctly inserted; open the retaining clips, remove the VRM, and then reinsert it.
