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:
•
Balance the server 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 the server.
5.1.3 Electrical Grounding Requirements
The server must be grounded properly for optimal 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,
and 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 servers connected to
the same power source, Inspur recommends the use of a 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 server is not
recommended.
5.2 Identifying the Contents of the Server Shipping Carton
Unpack the server shipping carton and locate the materials necessary for installing the
server. All the rack mounting hardware necessary for installing the server into the rack is
included with the rack or the server.
The contents of the server shipping carton include:
•
Server
•
Power cord
•
Rack-mounting hardware
