HP P2000 HP MSA System Racking Instructions - Page 3

Power requirements Installation of this equipment must comply with local and regional electrical regulations governing the installation of IT equipment by licensed electricians. This equipment is designed to operate in installations covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75, 1992 (code for Protection of Electronic Computer/Data Processing Equipment). For electrical power ratings on options, see the product rating label or the user documentation supplied with that option. WARNING! To reduce the risk of personal injury, fire, or damage to the equipment, do not overload the AC supply branch circuit that provides power to the rack. Consult the electrical authority having jurisdiction over wiring and installation requirements of your facility. Rack warnings 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 be- come unstable if more than one component is extended for any reason. CAUTION: Protect the enclosure from power fluctuations and temporary interruptions with a regulating UPS. This device protects the hardware from damage caused by power surges and voltage spikes and keeps the enclosure in operation during a power failure. When installing more than one enclosure, you may need to use additional power distribution devices to safely provide power to all devices. Observe the following guidelines: • Balance the enclosure power load between available AC supply branch circuits. • Do not allow the overall system AC current load to exceed 80 percent of the branch circuit AC current rating. • Do not use common power outlet strips for this equipment. • Provide a separate electrical circuit for each power supply in the en- closure. Electrical grounding requirements The enclosure must be grounded properly for proper operation and safety. In the United States, you must install the equipment in accordance with NFPA 70, 1999 Edition (National Electric Code), Article 250, as well as any local and regional building codes. In Canada, you must install the equipment in accordance with Canadian Standards Association, CSA C22.1, Canadian Electrical Code. In all other countries, you must install the equipment in accordance with any regional or national electrical wiring codes, such as the International Electrotechnical Commission (IEC) Code 364, parts 1 through 7. Furthermore, you must be sure that all power distribution devices used in the installation, such as branch wiring and receptacles, are listed or certified grounding-type devices. Because of the high ground-leakage currents associated with multiple enclosures connected to the same power source, HP recommends the use of a power distribution unit (PDU) that is either permanently wired to the building's branch circuit or includes a nondetachable cord that is wired to an industrial-style plug. NEMA locking-style plugs or those complying with IEC 60309 are considered suitable for this purpose. Using common power outlet strips for the enclosure is not recommended. 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.
