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 2 EIA units of rack
space (8.9cm 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 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:
lAlways 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.
lFollow prescribed leveling procedures from the rack cabinet manufacturer.
lNever 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.
lVerify the rack cabinet meets all safety requirements when configured with storage enclosures.
lVerify connections comply with all electrical requirements.
lVerify 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 stabilizing 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 an 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.

Mount the 2U enclosure into the rack cabinet
WARNING! Serious injury and mechanical failure can result if you do not adhere to rack cabinet safety precautions.
lTo avoid risk of death or injury from tipping the rack, follow all rack installation guidelines, securing the rack cabinet to the
floor with a concrete anchor kit.
lTo avoid catastrophic failure of the rack assembly, never exceed rack cabinet weight limits.
lEntirely support the storage enclosure with the mechanical lift until the enclosure is in the storage position.
lFollow local occupational health and safety guidelines and meet all requirements for manual material handling.
Mounting the storage enclosure into the rack cabinet is the most critical of installation procedures and requires your full
attention. Safety and hardware longevity depend on the rail's smooth function and correct implementation of this task.
lMake sure there is sufficient clearance for a technician and the storage enclosure in front of the rack cabinet.
lObserve rack cabinet weight limits.
lFill the rack cabinet from the bottom to the top, with the heaviest equipment at the bottom.
lMake your approach with the mechanical lift level, straight, and parallel to the rack cabinet. Any skew, warp, or tilt prevents
the inner rails attached to the storage enclosure from properly engaging the outer rails in the rack cabinet.
