Removing a fan module

You can remove a fan module from a 5U expansion enclosure.

Before you begin

Important: You can remove a fan module without powering off the expansion enclosure. However, to maintain operating temperature, do not remove more than one fan module at a time.
  • Remove a faulty fan module only when its replacement is ready to be installed.
  • Do not remove a fan module from an operational enclosure for more than approximately 10 minutes. The reduction in airflow through the enclosure might cause the enclosure or its components to shut down to protect from overheating.

About this task

Note: If you plan to remove the expansion enclosure from the rack, you must remove all of the fan modules.

Procedure

  1. Identify the fan module to be replaced. When lit, the amber LED on the front of the fan module ( 1   in Figure 1) identifies a fault.

    You can also issue the lsenclosurefanmodule command to display the status of the fan modules.

  2. Press the release tab on the fan module, as Figure 2 shows.
