    Electrical current from power, telephone, and communication cables is hazardous.

    To avoid a shock hazard:

    • Connect all power cords to a properly wired and grounded electrical outlet/source.
    • Connect any equipment that will be attached to this product to properly wired outlets/sources.
    • When possible, use one hand only to connect or disconnect signal cables.
    • Never turn on any equipment when there is evidence of fire, water, or structural damage.
    • The device might have more than one power cord, to remove all electrical current from the device, ensure that all power cords are disconnected from the power source.
    NEVER CONNECT AND DISCONNECT THE POWER SUPPLY CABLE AND EQUIPMENT WHILE YOUR EQUIPMENT IS POWERED ON WITH DC SUPPLY (hot-plugging). Otherwise you may damage the equipment and result in data loss, the damages and losses result from incorrect operation of the equipment will not be covered by the manufacturers’ warranty.
    Attention
    This type of power supply is hot-swap only when two power supplies are installed for redundancy. If only one power supply is installed, you must power off the server first before removing the power supply.

    The following tips describe the information that you must consider when you install a power supply with dc input.

    CAUTION
    The power-control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.

    shock hazard
    CAUTION

    Never remove the cover on a power supply or any part that has this label attached. Hazardous voltage, current, and energy levels are present inside any component that has this label attached. There are no serviceable parts inside these components. If you suspect a problem with one of these parts, contact a service technician.

The following tips describe the type of power supply that the server supports and other information that you must consider when you install a power supply:

  • The standard shipping has only one power supply installed in the server. For redundancy and hot-swap support, you must install an additional hot-swap power supply. Certain customized models might be shipped with two power supplies installed.

  • Ensure that the two power supplies installed on the server have the same wattage.

  • If you are replacing the existing power supply with a new power supply of different wattage, attach the power information label that comes with this option onto the existing label near the power supply.

  • Ensure that the devices that you are installing are supported. For a list of supported optional devices for the server, go to: Lenovo ServerProven website

Attention

  • Read the Installation guidelines to ensure that you work safely.

  • Touch the static-protective package that contains the component to any unpainted metal surface on the server; then, remove it from the package and place it on a static-protective surface.

Procedure

  1. If there is a power supply bay filler installed, remove it.
    Important
    During normal operation, each power supply bay must contain either a power supply or power supply filler for proper cooling.
