3. Swing the bezel away from the chassis, disengage the three retaining hooks on
the bezel, and carefully pull it away from the chassis.
To replace the bezel, fit the bezel's three retaining hooks into their corresponding
slots on the chassis. Rotate the bezel toward the chassis until the hooks snap into the
slots.
The drive cage (see Figure 3-2) holds the externally accessible drives except for the
standard 3.5-inch diskette drive. It holds up to two half-height, 5.25-inch devices and
two 3.5-inch devices in the mini tower chassis. In the desktop chassis, it holds up to
two half-height, 5.25-inch devices and one 3.5-inch device. The drive cage must be
removed to install a drive in one of its bays.
To remove the drive cage, perform the following steps:
1. Remove the bezel as described in the previous section.
2. Note the location and orientation of any cables attached to devices in the drive
cage; then disconnect the cables.
3. Remove the screw at the side of the drive cage (see Figure 3-2).
4. Slide the drive cage toward you about one inch. Then lift it out of the chassis.
NOTE: The drive cage has slots on the sides and bottom that engage tabs in the
chassis. Three of these tabs contain a detent feature that locks the drive cage
into place. The drive cage may be slightly difficult to slide forward until it is
detached from the detents.
