Server setup 31
Power requirements
Installation of this equipment must comply with local and regional electrical
regulations governing the installation of information technology equipment by
licensed electricians. This equipment is designed to operate in installations
covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75, 1992
(code for Protection of Electronic Computer/Data Processing Equipment). For
electrical power ratings on options, refer to the product rating label or the user
documentation supplied with that option.
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.
