2-4 Planning Your Site Environmental Condi tions The location should be examined for the following environmental hazards: ! Dust - floating dust must be kept to no more than 0.
Planning Your Site 2-5 Floor Constr uction Aspects of floor construction, such as load cap acity and construction materials, must be considere d when installing one or more rac k s y stems. Note: The r ack suppor ts up to 55 1.2 lbs. ( 250 k g). Use Table 2-1 to calculate th e load that each r ack of your system configurat ion places on the floor.
2-6 Planning Your Site If you do not know the load capacity of your flooring, consult y our building manager or an archi tect. In many instances the equipment is installed dire ctly on the existing floor and interconnecting power cables a re protected by cable covers.
Planning Your Site 2-7 System Rack Placement The system rac k comes equipped with a front stabilizer that: ! steadies the rack when you extend equipm ent for servicing, and ! prevents creeping due to vibration. The stabilizer is pr edrilled to allow y ou to secure the system rack to the floor.
2-8 Planning Your Site Figure 2-2. Distance Between Stabilizer Anchors If the rack is installed on a concrete floor, you can bolt the rack to the floor using 3/8" concrete drop-in anchors and 1½ "-16 bolts.
Planning Your Site 2-9 Air Conditioning A properl y sized air conditioning s y stem ensures stabl e and reliable operation of y our servers b y performing the following tasks: ! cooling the s yste m ! preventing the generation of stati c charges ! preventing the formation of corrosion causin g condensation within the sy st em.
2-10 Planning Your Site The air conditioner’s capacit y must be larger than the sum of the above items. Use Table 2-3 to calculate calori fic values – in BTUs.
Planning Your Site 2-11 Grounding Requirements The system rack must have a dedi cated ground attached to the powe r distribution panel. The ground wire must have an earth r esistance of 100 ohms or less and depending on y our local electric al code, a thickness of 38 mm 2 or more.
