Grounding Requirements
For proper operation and safety, the server must be properly grounded. 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, the equipment must be installed in accordance with Canadian Standards
Association, CSA C22.1, Canadian Electrical Code. In all other countries, the
installation must follow any regional or national electrical wiring codes, such as the
International Electrotechnical Commission (IEC) 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 servers
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. HP does not recommend using common power outlet strips for this
equipment.
