Step 6 Pull the power supply out of the bay and set it aside.

Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029

Step 7 If the power supply bay is to remain empty, install a blank power supply filler plate over the opening. Secure the filler plate with the two mounting screws and tighten them with a screwdriver.

Installing an AC-Input Power Supply

Warning The plug-socket combination must be accessible at all times, because it serves as the main disconnecting device. Statement 1019

Follow these steps to install an AC-input power supply:

Step 1 Make sure that the power supply you are installing is not plugged in to a power outlet and that the power cord is not connected to the power supply.

Step 2 Remove the two Phillips-head screws from the power supply filler plate (if a filler plate is present). Step 3 Remove the power supply filler plate (if one is present) and set it aside.

Caution Use both hands to grasp a power supply.

Step 4 Grasp the power supply handle with one hand. Place your other hand underneath to support the bottom of the power supply, as shown earlier in Figure 4-8.

Step 5 Slide the power supply all the way into the power supply bay.
