WARNING: The server is heavy. To reduce the risk of personal injury or damage to the equipment, do the following:
• Observe local occupational health and safety requirements and guidelines for manual material handling.
• Get help to lift and stabilize the product during installation or removal, especially when the product is not
fastened to the rails. The server weighs more than ( ), so at least two people must lift the server into the
enclosure together. An additional person may be required to help align the server if the server is installed higher
than chest level.
• Use caution when installing the server in or removing the server from the enclosure.
• Adequately stabilized the enclosure before extending a component outside the enclosure. Extend only one
component at a time. A enclosure may become unstable if more than one component is extended.
• Do not stack anything on top of rail-mounted component or use it as a work surface when extended from the
rack.
WARNING: To reduce the risk of personal injury or damage to the equipment, observe the following precautions:
• 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.
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 21 m (7 ft) tall, and might 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.
CAUTION: Always plan the rack installation so that the heaviest item is on the bottom of the rack. Install the
heaviest item first, and continue to populate the rack from the bottom to the top.
CAUTION: Before installing the server in a enclosure, be sure to properly scope the limitations of the enclosure.
Before proceeding with the installation, consider the following:
• You must fully understand the static and dynamic load carrying capacity of the enclosure and be sure that it can
accommodate the weight of the server.
• Be sure suicient clearance exists for cabling, installation and removal of the server, and movement of the rack
doors.
