Replacing a power supply module

How to replace a power supply module.

Before you begin

You must have part 03KE102 available.

About this task

There are two hot-swap power supplies in the rear of the appliance. You must replace a power supply module as soon as possible if any of the following situations occur or when directed by IBM® Support.
  • When the appliance generates a critical or warning message to indicate which power supply module is in a failure state.
  • When the LED on one of the power supply modules is illuminated red.
DANGER
Hazardous voltage, current, or energy levels are present inside any component that has this label attached. Do not open any cover or barrier that contains this label. (L001)
DANGER
Rack-mounted devices are not to be used as shelves or work spaces. Do not place objects on top of rack-mounted devices. In addition, do not lean on rack-mounted devices and do not use them to stabilize your body position (for example, when working from a ladder). (L002)

Procedure

  1. Unplug the power cord of the failed module.
  2. Remove the power supply module.
    The following figure shows the components that are mentioned.

    1. Firmly grip the handle  A  of the failed module.
    2. Push the release latch  B  toward the handle and hold in this position.

  4. Unpack the replacement module.
  5. Replace the module.
    1. Carefully align the replacement module with the open space in the appliance.
    2. Completely insert the module until the release latch clicks into place.
    3. Pull the handle to ensure that the module is secure.
  6. Plug in the power cord to the replaced module.
  7. Verify that the new module is working.
    1. The power supply LED is illuminated green.
    2. The fault LED is not illuminated.

What to do next

After you verify that the replacement module is working, return the failed part to IBM.
