Power requirements
Installation of this equipment must comply with local and regional electrical
regulations governing the installation of IT 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 storage enclosure from power fluctuations
and temporary interruptions with a regulating UPS. This device protects
the hardware from damage caused by power surges and voltage spikes
and keeps the storage enclosure in operation during a power failure.
When installing more than one storage enclosure, you may need to use additional
power distribution devices to safely provide power to all devices. Observe the
following guidelines:
• Balance the storage enclosure 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 each power supply in the storage
enclosure.
