4. Locate two people to assist in moving the storage enclosure onto the mechanical lift, using an appropriate safe lifting technique to perform the following actions:
   a. Position a person on each side of the storage enclosure, grasping the chassis sides, not the front or rear panel.
   IMPORTANT Almost all the weight of the storage enclosure is to the rear, so prepare to lift more from the side of the chassis to the rear than from the chassis side to the front.
   b. Simultaneously lift the storage enclosure, using the appropriate safe lifting technique while moving it to a static-protected location, and then to the mechanical lift for mounting to the rack cabinet.

5. Complete the following actions to prepare the 2U chassis for installation:
   a. If drives are present in the chassis, grasp the latch of the first drive in its carrier (DDIC) between thumb and forefinger and squeeze together to release the latch, then pivot outward to release the DDIC from the midplane.
   b. Temporarily remove and store each DDIC in a static-protected environment.
   c. Facing the chassis front, grasp the right rack flange cover, work the cover free, and set it aside in a safe location.
   d. Grasp the left rack flange cover, gently work the cover free, and set it aside in a safe location.
   

Install the 2U rackmount rail kit

The storage enclosure requires rackmount hardware for installation into a standard 1.2m rack and occupies two (2) EIA units of rack space (8.89 cm or 3.50 inches) per unit.  The rail kit contains a left and right rail designed to handle the 2U storage enclosure and provide for the installation of multiple enclosures without loss of rack space. Product function and user safety hinge on proper installation. This task assumes square mounting holes but pertains to other rack types.
You must take all appropriate rack cabinet safety precautions before mounting a storage enclosure into a rack.

CAUTION Observe all the following directives:

• Always place the rack cabinet on a flat, leveled surface. Do not install a storage enclosure into a rack cabinet until you verify the rack cabinet is level.
• Follow prescribed leveling procedures from the rack cabinet manufacturer.
• Never install or remove from the rack cabinet more than one storage enclosure at a time. This helps prevent the rack cabinet from tipping or falling.
• Verify the rack cabinet meets all safety requirements when configured with storage enclosures.
• Verify connections comply with all electrical requirements.
• Verify the system complies with all temperature and exhaust requirements.

To adhere to safety precautions when mounting a storage enclosure into a rack cabinet:

1. Read and observe all warning and caution labels on the storage enclosure.
2. Verify the rack cabinet is on a flat, leveled surface because any incline or unevenness stresses the rack cabinet and storage enclosure. A storage enclosure in an uneven rack cabinet resists smooth rail movement and may distort the chassis.
3. Verify the rack cabinet design supports the total weight of storage enclosures and has to stabilize features to prevent the rack cabinet from tipping or being pushed over during installation or normal use.
4. Do not lift the storage enclosure without a mechanical lift. No single person should lift a storage enclosure without help.
5. Mount storage enclosures into the rack cabinet from the bottom to the top during installation.
6. Locate lighter storage enclosures above heavier ones to maximize stability.
7. Remove storage enclosures from the top of the rack cabinet to the bottom when emptying it.

To install the 2U rackmount rail kit:

1. Remove both outer rail assemblies from their packaging.
