Specifications and requirements
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 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).
NOTE: For power requirements, see the QuickSpecs: www.hpe.com/support/MSA1050QuickSpecs. If a website location
has changed, an Internet search for "HPE MSA 1050 quickspecs" will provide a link.
Weight and placement guidelines
Refer to
"Physical requirements" (page 70)
•
The weight of an enclosure depends on the number and type of modules installed.
•
Ideally, use two people to lift an enclosure. However, one person can safely lift an enclosure if its weight is reduced by
removing the power supply modules and disk drive modules.
•
Do not place enclosures in a vertical position. Always install and operate the enclosures in a horizontal/level
orientation.
•
When installing enclosures in a rack, make sure that any surfaces over which you might move the rack can support
the weight. To prevent accidents when moving equipment, especially on sloped loading docks and up ramps to raised
floors, ensure you have a sufficient number of helpers. Remove obstacles such as cables and other objects from the
floor.
•
To prevent the rack from tipping, and to minimize personnel injury in the event of a seismic occurrence, securely
anchor the rack to a wall or other rigid structure that is attached to both the floor and to the ceiling of the room.
