Installing or replacing the top cover

You can replace the top cover on a 5U expansion enclosure during the installation process or after you complete a service task.

Before you begin

Important: You can install the cover while the expansion enclosure is powered on. To maintain operating temperature, replace the cover within 15 minutes of completing other service tasks. When the cover is removed, the reduction in airflow through the enclosure might cause the enclosure or its components to shut down to protect from overheating.
