Space planning requirements
Space planning involves ma king sure that your computer room:
• Is large eno
ugh to h old 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 fl oor
• Includes correctly positioned floorcutoutsforthesystem’spoweranddatacables
The space planning process
1. Document your computer room’s existing floor plan, including locations of these items:
a. Im m ovable objects, such as structural suppor t 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. Developanewfloor plan tha t includes the locations of all of the above items p lus the system and
any new items added to support it. Include flexibility to accommodate additional equipment as
your requirements increase.
3. Implement the new floorplan,leavingemptyspacewherethesystemwillbeinstalled.Ifthenew

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 comm on 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
• Pro
vides an under-floor area for running interconnecting cables conveniently and unobtrusively
• Allows op timum distribution of conditioned air
WARNING!
If m etal 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.
• Gridpanelsmustbeatleast450x450mm(17.72x17.72in).
• 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 1 02.4 lb per square foot). The maximum fl oor loading at any
point is 500 kg (1102.3 lb).
