Dell R515 owner manual Power Supplies, Removing a Power Supply, 102

Power Supplies

Your system supports 750 W power supply.

NOTE: The maximum output power (shown in watts) is listed on the power supply label.

If two power supplies are installed, the second power supply provides hot-swappable, power redundancy. When a power supply is removed with the system powered on, the full power load is picked up by the remaining power supply.

CAUTION: To ensure proper system cooling, the power supply blank must

be installed in the PS2 bay in a redundant configuration. See "Installing the Power Supply Blank" on page 104.

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

Removing a 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 3-15.

NOTE: Install a power supply blank if you are not replacing the power supply. See "Installing the Power Supply Blank" on page 104.
