When installing more than one server, additional power distribution devices may be
required to safely provide power to all devices. Observe the following guidelines:
• The power load must be balanced between available AC supply branch circuits.
• The overall system AC current load must not exceed 80 percent of the branch
circuit AC current rating.
Grounding Requirements
For proper operation and safety, the server must be properly grounded. In the United
States, 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, install the equipment 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, ensure that
all power distribution devices used in the installation—such as branch wiring and
receptacles—are listed or certified grounding-type devices.
Because 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
non-detachable 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.
