Server blade warnings and cautions WARNING: To reduce the risk of injury from high-current electrical energy, do not remove the server blade access panel when power is applied through the HP ProLiant p-Class diagnostic station. Remove all power from the server blade before removing the access panel. WARNING: To reduce the risk of shock or injury from high-current electrical energy, do not remove the server blade access panel while the server blade is installed in the server blade enclosure. Do not remove the server blade access panel and then install the server blade into the server blade enclosure. WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system components to cool before touching them. CAUTION: When performing non-hot-plug operations, you must power down the server blade and/or the system. However, it may be necessary to leave the server blade powered up when performing other operations, such as hot-plug installations or troubleshooting. 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: When installing a server in a telco rack, be sure that the rack frame is adequately secured to the top and bottom of the building structure. 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.
