Then push the power supply inward until the connectors engage and latch. The latch should slide up. You feel a slight resistance as the connectors engage. CAUTION: If the resistance is too great, the connectors may not be aligned. Forcing the power supply inward could damage the connectors. If necessary, remove and reinsert the power supply, ensuring that the connectors are properly aligned. 6 Tighten the captive screws that secure the power supply to the chassis. 7 Plug the power cord into the system. 8 Plug the other end of the power cord into the building's power outlet. If your system has two power supplies, be sure to plug in the second power supply. Leaving the second power supply unplugged causes the system diagnostics to generate a power supply error.
