Dell R510 owner manual Removing a Redundant Power Supply

NOTE: If only one power supply is installed, it must be installed in the PS1 power supply bay.

Removing a Redundant Power Supply

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.

CAUTION: The system requires one power supply to operate the system normally. On power-redundant systems, remove and replace only one power supply at a time in a system that is powered on.

1Disconnect the power cable from the power source.

2Disconnect the power cable from the power supply and remove the system cables from the Velcro straps.

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.

3Press the lever release latch and slide the power supply out of the chassis. See Figure 3-17.

NOTE: Install a power supply blank if you are not replacing the power supply. See "Installing the Power Supply Blank" on page 112.
