Table62:Power requirements - AC Input
l All AC mains and supply conductors to power distribution boxes for the rack-mounted system must be
enclosed in a metal conduit or raceway when specified by local, national, or other applicable government
codes and regulations.
l Ensure that the voltage and frequency of your power source match the voltage and frequency inscribed
on the equipment’s electrical rating label.
l To ensure redundancy, provide two separate power sources for the chassis . These power sources
must be independent of each other, and each must be controlled by a separate circuit breaker at the
power distribution point.
l The system requires voltages within minimum fluctuation. The customer-supplied facilities’ voltage must
maintain a voltage with not more than ± 5 percent fluctuation. The customer facilities must also provide
suitable surge protection.
l Site wiring must include an earth ground connection to the AC power source. The supply conductors
and power distribution boxes (or equivalent metal chassis) must be grounded at both ends.
l Power circuits and associated circuit breakers must provide sufficient power and overload protection. To
prevent possible damage to the AC power distribution boxes and other components in the rack, use an
external, independent power source that is isolated from large switching loads (such as air conditioning
motors, elevator motors, and factory loads).
Site Wiring and DC Power Requirements
The following are required for all installations using DC power supplies:
