Step 2: Remove the
Protective Covers
1. Disconnect the DPI cable from the HIM assembly (if present).
2. Loosen, but do not remove, the screws that secure the bottom cover to
the drive, then slide the cover down and off the drive chassis.
3. Loosen, but do not remove, the screws that secure the top cover to the
drive, then slide the cover up and off the drive chassis.
Important: The HIM assembly is connected via a cable to the Control
board and therefore will not pull free from the drive until
disconnected. See step 4 below for instructions.
