a. Release the levers on each side of the drawer by pulling both levers
towards the center. At the front of the storage expansion enclosure, pull
the handles on the drive drawer to be removed until the drive drawer
stops. The drive drawer should not come completely out of the enclosure
at this time.
b. Slide the drive drawer release lever (see Figure 65) on both sides of the
drive drawer toward you, and remove the drive drawer from the
enclosure.
Important: To remove second to fifth disk drawers, you have to lift the
lockout tumblers on the right side of the enclosure. The tumblers prevent
more than one disk drive drawer from being pulled out simultaneously.
9. Loosen the thumbscrews that attach the rear brackets to the enclosure (one on
each side of the enclosure).
10. On the front of the enclosure, remove the four M5 screws that attach it to the
chassis (two screws on each side).
