Replacing a Fan Module

Replacing a Fan Module

This section describes how to replace a fan module.

Impact on the System

During the replacement of a fan module, the system's heat dissipation is affected, degrading the system reliability.


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


  • Do not touch rotating fan blades.
  • Remove and insert a fan module with even force. Excessive force may damage the connectors or appearance of the fan module.
  • Remove only one fan module at a time.
  • After removing a fan module, install a new one within two minutes. Otherwise, the system heat dissipation is compromised.

Tools and Materials

  • ESD wrist strap
  • ESD bag
  • Label


  1. Wear an ESD wrist strap.
  2. Press the latch on the fan module and pull out the fan module, as shown in Figure 6-4.

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

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

    • 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 fan module slot is faulty, or the fan module is incorrectly installed.
