Installing or replacing a fan module
You can reinstall a fan module or replace a faulty fan module in a 5U expansion enclosure.
Before you begin
Important: You can replace a fan module without powering off the expansion enclosure.
However, to maintain operating temperature, replace the fan module within 10 minutes of its removal.
When a fan module is removed, the reduction in airflow through the enclosure might cause the
enclosure or its components to shut down to protect from overheating.
About this task
The expansion enclosure might or might not be powered on, depending on the number of fan modules that need to be replaced. For example, the expansion enclosure must be powered off if all four fan modules are removed.
This task assumes that the following condition was met:
Procedure
-
Hold the fan module with the release tab on top and the connector pin on the bottom, as shown
in Figure 1.

-
Carefully insert the fan module into the chassis until it clicks in place, as shown in Figure 2.
