8.5Troubleshooting
The following sections describe common problems (and possible solutions) you might encounter with your drive enclosure system.
8.5.1Thermal Control
The drive enclosure uses extensive thermal monitoring and takes a number of actions to ensure component temperatures are kept low and also to minimize acoustic noise. Air flow is from the front, over the drive section, through the midplane, through the I/O modules to rear of the enclosure.
