Rack warnings and cautions 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: This server blade 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. • Get help to lift and stabilize the product during installation or removal, especially when the product is not fastened to the rails. When the server blade enclosure weighs more than 22.5 kg (50 lb), at least two people must lift the server blade enclosure into the rack together. A third person may be required to help align the server blade enclosure if the server blade is installed higher than chest level. • Use caution when installing the server blade enclosure in or removing the server blade enclosure from the rack; it is unstable when not fastened to the rails. WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system components to cool before touching them. Preparation procedures To access some components and perform certain service procedures: • Back up all critical data. • Power down the server blade (on page 13). For non-hot-plug service procedures, use the methods available to power down the server blade. • Remove the server blade (on page 13). Access to internal server blade components requires removal from the server blade enclosure and HP ProLiant p-Class sleeve. Removal and replacement procedures 12
