B Environmental requirements and specifications
Safety requirements
Install the system in accordance with the local safety codes and regulations at the facility site. Follow all
cautions and instructions marked on the equipment. Also, refer to the documentation included with your
product’s ship kit.
Site requirements and guidelines
The following sections provide requirements and guidelines that you must address when preparing your site
for the installation.
When selecting an installation site for the system, choose a location not subject to excessive heat, direct
sunlight, dust, or chemical exposure. These conditions greatly reduce the system’s longevity and might void
your warranty.
Site wiring and AC power requirements
The following are required for all installations using AC power supplies:
• 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.
• Ensure that the voltage and frequency of your power source match the voltage and frequency inscribed
on the equipment’s electrical rating label.
• To ensure redundancy, provide two separate power sources for the enclosures. These power sources
must be independent of each other, and each must be controlled by a separate circuit breaker at the
power distribution point.
• 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.
• Site wiring must include an earth ground connection to the AC power source. The supply conductors
and power distribution boxes (or equivalent metal enclosure) must be grounded at both ends.
• 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:
• All DC mains and supply conductors to power distribution boxes for the rack-mounted system must
comply with local, national, or other applicable government codes and regulations.
• Ensure that the voltage of your power source matches the voltage inscribed on the equipment’s
electrical label.
• To ensure redundancy, provide two separate power sources for the enclosures. These power sources
must be independent of each other, and each must be controlled by a separate circuit breaker at the
power distribution point.
• The system requires voltages within minimum fluctuation. The customer-supplied facilities’ voltage must
maintain a voltage within the range specified on the equipment’s electrical rating label. The customer
facilities must also provide suitable surge protection.
• Site wiring must include an earth ground connection to the DC power source. Grounding must comply
with local, national, or other applicable government codes and regulations.
• Power circuits and associated circuit breakers must provide sufficient power and overload protection.
