5. Remove a dummy sponge from the slot, see Figure 4-53.
Note: The dummy sponge is provided to maintain the
proper cooling effect. Leave the dummy sponge in unused
slots so that the DEU can operate efficiently.
(Keep all removed dummy sponges for future use.)
!
CAUTION
Do not insert your hand or any tool into the slot with the disk
tray or dummy sponge removed. Failure to follow this
caution may cause an electric shock or fire.

Note: Observe static precautions. Use an antistatic
wrist strap.
6. The drive carrier is shipped with the add-on drive. Remove the new drive
from its protective wrapper and place it on an antistatic surface. Record the
drive model and serial numbers in the equipment log.
7. Position the drive so its SCA connector is near the top surface of the drive.
Place the drive on the antistatic surface again. Slide the drive into the carrier
with its SCA connector facing toward the rear of the carrier (open end).
8. While holding the drive in the carrier with your left hand, align the drive’s
screw holes with the carrier’s screw holes and insert the four screws of
appropriate size and length (see Figure 4-54).
