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. 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 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.

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

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.
