Space planning requirements Space planning involves making sure that your computer room: • Is large enough to hold the new system and other equipment and furniture • Provides clearance around the system for service access and to ensure proper weight distribution on the computer room's floor • Includes correctly positioned floor cutouts for the system's power and data cables The space planning process 1. Document your computer room's existing floor plan, including locations of these items: a. Immovable objects, such as structural support columns b. Walls c. All equipment, furniture, cabinets, racks, data comm equipment, and systems d. Floor cutouts e. Electrical outlets f. Interconnecting cables and power cords, including lengths g. Floor vents 2. Develop a new floor plan that includes the locations of all of the above items plus the system and any new items added to support it. Include flexibility to accommodate additional equipment as your requirements increase. 3. Implement the new floor plan, leaving empty space where the system will be installed. If the new floor plan requires construction changes, consult with local contractors and by phone with your HP representative. Raised floor requirements 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. A raised floor: • Allows weight to be spread evenly across the floor • Provides an under-floor area for running interconnecting cables conveniently and unobtrusively • Allows optimum distribution of conditioned air WARNING! If metal is used in the construction of the raised floor, ensure that there is a common ground connection between the raised floor and main floor to avoid possible build up of different voltage potentials. Failure to comply can result in serious injury to personnel and damage to equipment. Requirements for raised floors: • Raised floor access ramps must not exceed a 10 degree slope. • Use a raised floor system (254 to 305 mm, 10 to 12 inches) for the most favorable room air distribution system. • Grid panels must be at least 450 x 450 mm (17.72 x 17.72 in). • The floor must have a load rating between 300 and 500 kg per square meter (553 to 921.7 lb per square yard, or 61.4 to 102.4 lb per square foot). The maximum floor loading at any point is 500 kg (1102.3 lb). 22 Site requirements
