28 Chapter 5 Installation of 5U enclosures
4. Locate three 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 one person at the front to grip the front belt strap securely by both loops, not by any portion of
the front or rear panel areas.
b. Position one person at each rear corner to grip both rear belt straps by the loops on that side.
c. Simultaneously lift the storage enclosure, using 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. Facing the front of the chassis, grasp the right rack flange cover, gently work the cover free, and set it aside
in a safe location.
6. Grasp the left rack flange cover, gently work the cover free, and set it aside in a safe location.
Install the 5U rackmount rail kit
The storage enclosure requires rackmount hardware for installation into a standard 1.0m or 1.2m rack and
occupies 5 EIA units of rack space (22.22cm or 8.75 inches) per unit. The rail kit contains a left and right rail
designed and tested to handle the 5U storage enclosure and provide for installation of multiple enclosures
without loss of rack space. Product function and user safety hinge on their proper installation. The following
task assumes your rack posts have square mounting holes.
You must take all appropriate rack cabinet safety precautions before mounting a storage enclosure into a rack.
CAUTION Observe all the following directives:
l
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.
l
Follow prescribed leveling procedures from the rack cabinet manufacturer.
l
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.
l
Verify the rack cabinet meets all safety requirements when configured with storage enclosures.
l
Verify connections comply with all electrical requirements.
l
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 the storage enclosure. A storage enclosure in an uneven rack cabinet resists smooth
movement on the rails and possibly distorts the storage enclosure.
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 ever lift a storage
enclosure without assistance.
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.
