Replacing a Power Module

This section explains how to replace a power module for a P12.

Impact on the System

There is no impact on the system.

Prerequisites

  • The replacement power module is ready.
  • The faulty power module has been located.
  • The power cable has been disconnected from the power module that you want to replace.

Precaution

Before replacing a power module, disconnect it from the external power source. Otherwise, device damage or even personal injury may occur.
