Step 2: Remove the
Protective Covers
1. Disconnect the DPI cable from the HIM assembly (if present).
2. Remove the screws that secure the bottom cover to the drive, then slide
the cover down and off the drive chassis.
3. Press in on the sides at the bottom edge of the top cover and at the same
time pull the cover toward you to pull it partially off the drive chassis.
4. At the top of the drive, pull the cover forward, away from the drive, until
the pins fit in the keyhole in the top of the cover, then carefully lift the
cover off of 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 page 4
for instructions.
