6.Plug one end of the power cords into the AC input receptacles on the rear of the DEU and connect the other end into the AC wall outlets. The "POW" LED on the two power supplies light indicating that AC power is applied to them and that everything is OK.

Removing a Power Supply

To remove a power supply from the BSU or DEU, perform the following steps.

1.Observe the safety and ESD precautions listed at the beginning of this chapter.

2.Power off the system.

3.Unplug the power cords from the AC wall outlet and from the input receptacle on the rear of the power supply you are removing.

4.If removing a power supply from the BSU hold its front lever and pull the power supply out of the bay.

5.If removing a power supply from the DEU loosen the thumb lock screws that secure the power supply to the bay and pull it out of the bay, see Figure 4-66.

6.If you are replacing a BSU or DEU power supply.

Note: If a power supply is not being replaced, install a blank cover over the empty bay to maintain the proper cooling effect.
