Replacing a Power Module

Replacing a Power Module

This section describes how to replace a power module.

Impact on the System

During the replacement of a power module, if the redundant power module fails, the corresponding enclosure is unexpectedly powered off, degrading the system reliability.

Prerequisites

  • The replacement power module is ready.
  • The power module that you want to replace has been located.

Precaution

  • Remove and insert a power module with even force. Excessive force may damage the appearance or connectors of the power module.
  • Remove only one power module at a time.
  • Shorten the duration of replacing a power module as much as possible.

Tools and Materials

  • ESD wrist strap
  • ESD bag
  • Label

Procedure

  1. Wear an ESD wrist strap.
  2. Press the latch on the power module and pull out the power module, as shown in Figure 6-1.

  3. Put the removed power module into an ESD bag.
  4. Take the replacement power module out of its ESD bag.
  5. Insert the replacement power module into the empty slot until it clicks into place, as shown in Figure 6-2.

  6. Wait about one minute and check the status of the Running/Alarm indicator on the power module to determine whether the power module is successfully installed. Figure 6-3 shows the location of the Running/Alarm indicator.

    • If the indicator is steady green, the power module is successfully installed.
    • If the indicator is steady red or off, the newly installed power module is faulty, the power module slot is faulty, or the power module is incorrectly installed.
