Installing the Appliance in the Rack
WARNING: It is recommended that a mechanical lifter
(or at least two people) be used to prevent injury during
rack removal and reinsertion.
1. At the front of the rack, pull out the middle members
until they lock (click) in the extended position.
2. Confirm that the ball-bearing shuttle is all the way to
the front of the middle member (Figure 9).
Figure 9. Inserting Expansion Unit Into Rack
3. Using a mechanical lifter or two people, lift the
appliance to its install height and engage the inner
members mounted on the appliance with the middle
members protruding from the rack, sliding the
appliance into the rack until it stops.
4. Slide the unit in and out several times to ensure that
the rail members slide smoothly, the locks engage
properly, and the expansion unit does not bind.
If binding occurs, verify that the front and rear flanges
are mounted in the correct holes, readjusting the slide
positioning as necessary.
5. Using the two screws provided (Figure 10), secure the
expansion unit flanges to the rack.

Installing Drives
The drives come packed separately. Once the expansion
unit is in the rack, install the drives:
NOTE: Do not remove the disk drives from their carriers.
Doing so voids the drive warranty.
1. Position the drive carrier assembly with the button to
the right before you slide it into the chassis.
2. With the lever open, carefully insert the drive assembly
until it completely enters the bay.
3. Push the lever back in place to lock it (Figure 11 on
page 3).
