Install the hot-swap power supply unit

Follow instructions in this section to install the hot-swap redundant power supply unit.

About this task

To avoid potential danger, read and follow the following safety statements.
  • S001
    shock hazard
    DANGER
    danger
    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.
  • S002
    disconnect all power
    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.
  • S035
    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 configuration comes with one power supply unit without hot-swap support. Hot-swap support and power redundancy requires two power supply units installed in the system.

  • Power supply units in the chassis must have the same wattage, vendor, and part number (or alternate part number).

  • 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 Installation Guidelines and Safety inspection checklist to ensure that you work safety.

  • 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. Make preparations for this task.
    1. Make sure that the power supply unit to be installed is the same as the installed ones. Otherwise, remove all existing power supply units and replace them all with the same power supply units.
      Note

      • Power supply units in the chassis must have the same wattage, vendor, and part number (or alternate part number).

      • PSU with a release tab is a hot-swap PSU. The color of the release tab does not affect the serviceability of the PSU.

    2. If there is a PSU filler installed, perform the following steps:
      • Press the latch on the PSU filler.
      • Pull the filler out of the PSU slot.
      Important
      During normal operation, each power supply bay must contain either a power supply or power supply filler for proper cooling.

  2. Make sure the label on the power supply is facing up and the release latch is on the right side as illustrated below, and then slide it into the chassis until it snaps into place.
    Note

    • If more than one power supply units are to be installed, start with the upper available power supply bay.

After you finish

  1. Connect the power cable to the power supply and a properly grounded electrical outlet.

  2. Complete the parts replacement. See Complete the parts replacement.
