Install a hot-swap power supply

Use this information to install a hot-swap power supply.

Read the installation GuidelinesATTENTION: Static Sensitive Device Ground package before opening
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 devices that you are installing are supported. For a list of supported optional devices for the server, go to: Lenovo ServerProven website

    Note

    • 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.

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.

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

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.

Before installing the hot -swap power supply,

  1. 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.

To install the hot-swap power supply, complete the following steps:

  1. If there is a power-supply-bay filler installed, remove it.
    Important
    To ensure proper cooling during normal server operation, both of the power supply bays must be occupied. This means that each bay must have a power supply installed; or one has a power supply installed and the other has a power-supply filler installed.
