NFPA 75, 1992 Edition (code for Protection of Electronic Computer/Data

Processing Equipment). For electrical power ratings on options, refer to the

product’s rating label or the user documentation supplied with that option.

When installing more than one server, you may need to use additional power

distribution devices 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, 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 ensure 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, Compaq 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. Compaq does not

recommend using common power outlet strips for this equipment.
