Preparing for installation
Warning, caution, and important messages
WARNING: To reduce the risk of personal injury or damage to equipment, heed all warnings
and cautions throughout the installation instructions.
WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:
The leveling jacks are extended to the floor.
The full weight of the rack rests on the leveling jacks.
The stabilizing feet are attached to the rack if it is a single-rack installation.
The racks are coupled together in multiple-rack installations.
Only one component is extended at a time. A rack may become unstable if more than one
component is extended for any reason.
WARNING: To reduce the risk of personal injury or equipment damage when unloading a
rack:
At least two people are needed to safely unload the rack from the pallet. An empty 42U
rack can weigh as much as 115 kg (253 lb), can stand more than 2.1 m (7 ft) tall, and
may become unstable when being moved on its casters.
Never stand in front of the rack when it is rolling down the ramp from the pallet. Always
handle the rack from both sides.
WARNING: The enclosure is very heavy. To reduce the risk of personal injury or damage to
the equipment:
Observe local occupational health and safety requirements and guidelines for manual
material handling.
Remove all installed enclosure components from their enclosures before installing or moving
the enclosures.
Use caution and get help to lift and stabilize enclosures during installation or removal,
especially when the enclosure is not fastened to the rack.
WARNING: To reduce the risk of personal injury or damage to the equipment, you must
adequately support enclosures during installation and removal.
WARNING: Always use at least two people to lift an enclosure into the rack. If the enclosure is
being loaded into the rack above chest level, a third person must assist with aligning the
enclosure with the rails while the other two people support the weight of the enclosure.
