WARNING: To reduce the risk of personal injury, fire, or
damage to the equipment, do not overload the AC supply branch
circuit that provides power to the rack. Consult the electrical
authority having jurisdiction over wiring and installation
requirements of your facility.
CAUTION: Protect the server from power fluctuations and
temporary interruptions with a regulating uninterruptible power supply
(UPS). This device protects the hardware from damage caused by
power surges and voltage spikes and keeps the system in operation
during a power failure.
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.
Electrical Grounding Requirements
The server 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.
