With the handle (Figure 42), gently push the power

supply inward until the connectors engage.
You feel a slight resistance as the connectors engage.
CAUTION: If the resistance is too great, the power
supply connectors and the backplane connectors may
not be aligned properly. Do not force the power
supply into the slot or you can damage the
connectors. If necessary, remove and reinsert the
power supply, ensuring that the connectors are
aligned.
