Dell R410 owner manual Removing the Power Supply Blank, Installing the Power Supply Blank

NOTE: When installing, hot-swapping, or hot-adding a new power supply in a system with two power supplies, allow several seconds for the system to recognize the power supply and determine its status. The power-supply status indicator turns green to signify that the power supply is functioning properly (see Figure 1-6).

Removing the Power Supply Blank

If you are installing a second power supply, remove the power supply blank in bay PS2 by pulling outward on the blank.

CAUTION: To ensure proper system cooling, the power supply blank must be installed in power supply bay PS2 in a non-redundant configuration. Remove the power supply blank only if you are installing a second power supply.

Installing the Power Supply Blank

NOTE: Install the power supply blank only in power supply bay PS2.

To install the power supply blank, align the blank with the power supply bay and insert the blank into the chassis until it clicks into place.

Removing a Non-Redundant Power Supply

1Turn off the system and all attached peripherals.

2Disconnect the power cable from the power source.

3Disconnect the power cable from the power supply and remove the Velcro straps that bundle and secure the system cables.

NOTE: You may have to unlatch and lift the optional cable management arm if it interferes with power-supply removal. For information about the cable management arm, see the system’s rack documentation.

NOTE: Remove the power cord retention bracket that secures the system cables. See the Getting Started Guide that ships with your system for more information.

4Open the system. See "Opening the System" on page 82. Disconnect all the power cables from the power supply to the system board, hard drives and optical drive. See Figure 3-10.

5Loosen the screw securing the power supply to the chassis and lift the power supply to remove it from the chassis. See Figure 3-10.
