Enclosure bezel removal
TIP: Please refer to
enclosure front panel.
You may need to remove the bezel to access front panel components such as disk drive modules and ear kits. Although
disk module LEDs are not visible when the bezel is attached, you can monitor disk behavior from the management
interfaces (see
notification, the CLI, and the SMU for managing the storage system).
While facing the front of the enclosure, grasp the left and right ear covers, such that your fingers cup the bottom of each
ear cover, with thumb at the top of each cover. Gently pull the top of the bezel while applying slight inward pressure
below, to release the bezel from the ball studs.
NOTE: The bezel should be attached to the enclosure during operation to protect ear circuitry. To reattach the bezel to
the enclosure front panel, follow the instructions provided in
