Preparing for installation 25
Service and cable routing space requirements
This section contains information about space requirements and floor
loading for the HP Disk Array XP128.
Space planning
HP recommends that you prepare a revised floor plan showing the overall
location and arrangement of your computer room, including the addition of
your disk array. Enough room and lighting should be provided for people to
work effectively on a daily basis and for periodic servicing of equipment.
Be sure to consider interconnecting cables and power cord lengths when
planning your layout. Identify the location of all power outlets on the floor
plan. Plan to keep cables away from traffic areas to help prevent accidents
and equipment failures. Prior to installation, consult your site specialist
responsible for your computer room.
HP strongly discourages the use of carpeting, including antistatic varieties,
within 6.0 m (20 ft.) of the disk array. If this advice is not followed, you
should place static discharge mats where personnel must walk before
touching any part of the array. Failure to comply with this precaution can
result in equipment damage through static discharge.
If you are planning to construct a new computer room or modify an existing
site, first consult with your HP representatives and local contractors. It is
important to plan the site with future expansion in mind, so equipment can
be added without disturbing the computer operation.
Floor construction and loading
The computer room floor must be able to support the total weight of the
equipment as well as localized weight at each caster or foot of the
equipment cabinets. A common method of preparing an adequate floor for
a computer room is to construct a raised floor over the building floor. The
weight should be spread evenly and the flooring should provide an area
through which interconnecting cables can be run conveniently and
