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.

Before you install a hot-swap power supply:

Note

  1. Ensure that the devices you are installing are supported. For a list of supported optional devices for the solution, see http://www.lenovo.com/us/en/serverproven/.

  2. Do not install two power supply units with different wattages. Related information is available from the following:

    • Read the label on the top cover for maximum wattage output of installed power supply units. Only replace the existing units with those having the same wattage as marked on the label.

    • Check the rear of the node to ensure that there is no length difference between the two installed units. A visible difference in length means that the two units have different wattages, and one of them must be replaced.

Procedure performed by: customer or field service

Complete the following steps to install a hot-swap power supply.

  1. Slide the hot-swap power supply into the bay until the release latch clicks into place.
    Important

    During normal operation, each power-supply bay must contain either a power supply or power-supply filler panel for proper cooling.

  2. Connect one end of the power cord for the new power supply into the AC connector on the back of the power supply. Then, connect the other end of the power cord into a properly grounded electrical outlet.
