Removal and Replacement Procedures - Convertible Minitower (CMT) Chassis
7. Before reinstalling each drive into the chassis, turn the drive so that it is perpendicular to the
internal 3.5-inch drive. The drive should be parallel to the green latch drive bracket.
8. Slide the drive into the uppermost available bay until it snaps into place. When the drive is
properly inserted, the drivelock will secure it. Repeat this step for each drive.
Ä
CAUTION: The bottom 5.25-inch drive bay has a shorter depth than the upper two bays. The bottom
bay supports a drive that is no more than 6.7 inches in depth, including the cables that attach to the back
of the drive. Do not try to force a larger drive, such as an optical drive or MultiBay drive, into the bottom
bay. This could cause damage to the drive and the system board.
The use of unnecessary force when installing any drive into the drive bay may result in damage to the
drive.
9. Reconnect all power and data cables to the drives in the 5.25-inch drive bays.
10. Remove the bezel subpanel (Section 6.7).
Ä
CAUTION: Hold the subpanel straight when you pull it away from the front bezel. Pulling the subpanel
away at an angle could damage the pins that align it within the front bezel.
11. Reposition the bezel blanks within the subpanel in the proper orientation for the desktop
configuration.
