Replacing a power supply module

How to replace a power supply module for the M2004 appliance.

Before you begin

You must have part 03KE575 available.

About this task

At the rear of the appliance are two hot-swap power supply modules. Replace a power supply module as soon as possible if any of the following situations occur or when directed by IBM® Support.
  • The appliance generated a critical or warning message to indicate which power supply module is in a failure state.
  • The LED on a power supply module is illuminated and 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). Stability hazard:
  • The rack may tip over causing serious personal injury.
  • Before extending the rack to the installation position, read the installation instructions.
  • Do not put any load on the slide-rail mounted equipment mounted in the installation position.
  • Do not leave the slide-rail mounted equipment in the installation position.
