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 storage system 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 system in operation during a power failure.

When installing more than one storage system, you may need to use additional

power distribution devices to safely provide power to all devices. Observe the

following guidelines:

• Balance the storage system 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.
