Chapter 4 Removing and Replacing FRUs

Removing and Replacing the Power Supply

Step 6 Using a screwdriver, tighten the two captive installation screws (see Figure 4-1) on the front panel of the AC-input power supply.

Step 7 Make sure the power supply power switch is in the off position (O).

Step 8 Before you connect the power supply to a power source, ensure that all site power and grounding requirements have been met.

Step 9 Plug the power cord into the power supply (see Figure 4-9).

Step 10 Connect the other end of the power cord to an AC-power input source.

Caution In a system with multiple power supplies, connect each power supply to a separate AC power source. In the event of a power source failure, if the second source is still available, it can maintain maximum overcurrent protection for each power connection.

Step 11 Press the power switch down to the on () position (see Figure 4-10).

Step 12 Verify power supply operation by checking the power supply’s front-panel LEDs. You should see the following:

The LED labeled GOOD is green.

The LED labeled FAIL is not lit.

The LED labeled FAN OK is green.
