Replacing a Fan Module

Replacing a Fan Module

This section explains how to replace a fan module of the C72.

Impact on the System

During the replacement of a fan module, system heat dissipation and service processing capabilities are adversely affected.

Prerequisites

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

Precaution

  • Do not touch rotating fan blades.
  • Use care when you remove and insert a fan module to avoid any damage to the appearance or connectors of the fan module.
  • Remove only one fan module at a time.
  • Replace a fan module with two minutes to prevent services from being affected.

Tools and Materials

  • ESD wrist strap
  • ESD bag
  • Labels

Procedure

  1. Wear an ESD wrist strap.
  2. Press the latch on the fan module to release the handle, and pull out the fan module, as shown in Figure 5-17.

  3. Place the removed fan module into an ESD bag.
  4. Take the replacement fan module out of its ESD bag.

  6. Wait about two minutes and check the status of the activity/alarm indicator on the fan module to determine whether the fan module is successfully installed. Figure 5-19 shows the location of the activity/alarm indicator.

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