Installing or replacing a fan module: 2077-92F
You can reinstall a fan module or replace a faulty fan module in a 2077-92F 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:
• You removed a fan module, following the process described in “Removing a fan module: 2077-92F ” on
page 94.
Procedure
1. Hold the fan module with the release tab on top and the connector pin on the bottom, as shown in
Figure 79 on page 75.
