Important: Before you begin, make sure that you have a flat work surface
available next to the computer on which you can set down the drive cage (see step
5).
Complete the following steps to remove the speaker:
1. Turn off the computer and attached devices; then, disconnect all power cords
and external cables.
Note: Removing the speaker might be easier if the computer is turned on its
side.
2. Remove the cover and support bracket (see “Replacing the side cover” on
page 27 and “Replacing the support bracket” on page 29).
3. Remove the front bezel (see “Replacing the bezel” on page 30).
4. Remove all adapters and set them on a static-protective surface.
5. Disconnect from the hard disk drives any cables, such as the SCSI cable, that
are too short to allow the drive cage to rest on a clean work surface at the side
of the computer.
