Removal and Replacement Procedures

Rack Warnings and Cautions

WARNING: Because the rack allows stacking of computer components on a vertical rather than horizontal plane, be sure that precautions have been taken to provide for rack stability and safety. It is important to follow these precautions providing for rack stability and safety, and to protect both personnel and property. Heed all cautions and warnings throughout the installation instructions provided with the device.

WARNING: To reduce the risk of personal injury or damage to the equipment:

•Observe local occupational safety requirements and guidelines for heavy equipment handling.

•Obtain adequate assistance to lift and stabilize the product during installation or removal.

•Always load the heaviest item first, and load the rack from the bottom up. This makes the rack bottom-heavy and helps prevent the rack from becoming unstable.

•Extend the leveling jacks to the floor.

•Rest the full weight of the rack on the leveling jacks.

•Attach the stabilizing feet to the rack if it is a single-rack installation.

•The racks are coupled together in multiple-rack installations.

•Fully extend the bottom stabilizers on the equipment. Be sure that the equipment is properly supported/braced when installing options and boards.

•Be sure that the rack is adequately stabilized before extending a component outside the rack. Extend only one component at a time. A rack may become unstable if more than one component is extended for any reason.

•Do not attempt to move a fully loaded equipment rack. Remove equipment from the rack before moving the rack.

•At least two people are needed to safely unload the rack from the pallet. An empty 42U rack weighs 115 kg (253 lb), is over 2.1m (7 ft) tall, and may become unstable when being moved on its casters. Do not stand in front of the rack as it rolls down the ramp from the pallet; handle it from the sides. Stabilize the device by keeping the unit on the rails.

WARNING: To reduce the risk of personal injury or damage to the equipment, observe all warnings and cautions throughout this chapter.

WARNING: Do not exceed the level of repair specified in the procedures in the product documentation. All troubleshooting and repair procedures are detailed to allow only subassembly or module-level repair.
