Removing the top cover: 2145-92F

To perform service tasks, you might need to remove the top cover from a 2145-92F expansion enclosure.

Before you begin

Important: You can remove the cover without powering off the expansion enclosure. However, to maintain operating temperature, replace the cover within 15 minutes of its removal. 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.

Procedure

Use the slide rails to pull the enclosure out from the rack. See Removing an expansion enclosure from a rack: 2145-92F for details.
Slide the release latch ( 1 ) in the direction that is shown in Figure 1.
