Weight And Placement Guidelines - HP AA988A - Modular Smart Array Storage Controller SCSI User Manual

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).

Weight and Placement Guidelines

Refer to "Physical Requirements" on page 74 for detailed size and weight
specifications.
The weight of an enclosure depends on the number and type of modules installed,
■
as shown in Table A-2.
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 and cooling modules
and drive modules.
Do not place enclosures in a vertical position. Always install and operate the
■
enclosures in a horizontal 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.
