  • Page 20: Environmental Conditions

    Environmental Conditions The location should be examined for the following environmental hazards: Dust - floating dust must be kept to no more than 0.3 mg/m . Dust should be held to less than 0.15 mg/m Radio Frequency (RF) - Normally, there is no need to worry about the effect of radio frequency interference on computer operations.

  • Page 21: Floor Construction

    Floor Construction Aspects of floor construction, such as load capacity and construction materials, must be considered when installing one or more rack systems. Note: The rack supports up to 551.2 lbs. (250 kg). Use Table 2-1 to calculate the load that each rack of your system configuration places on the floor.

  • Page 22

    If you do not know the load capacity of your flooring, consult your building manager or an architect. In many instances the equipment is installed directly on the existing floor and interconnecting power cables are protected by cable covers. In other instances, raised floors – that form a double floor – are used. Some advantages of raised floors are: Interconnecting cables can be routed under the raised floor.

  • Page 23: System Rack Placement

    System Rack Placement The system rack comes equipped with a front stabilizer that: steadies the rack when you extend equipment for servicing, and prevents creeping due to vibration. The stabilizer is predrilled to allow you to secure the system rack to the floor. Note: If preparing the area prior to the arrival of the system, review the power cable restrictions given in “Electrical Facilities”...

  • Page 24

    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. If you are installing your rack in an area with a raised floor, you can use concrete drop-in anchors and 3/8"-16 threaded rod with washers and nuts to secure the rack to the concrete beneath the raised floor.

  • Page 25: Air Conditioning

    Air Conditioning A properly sized air conditioning system ensures stable and reliable operation of your servers by performing the following tasks: cooling the system preventing the generation of static charges preventing the formation of corrosion causing condensation within the system. The system rack’s temperature and humidity requirements are listed in Table 2-2.

  • Page 26: Electrical Facilities

    The air conditioner’s capacity must be larger than the sum of the above items. Use Table 2-3 to calculate calorific values – in BTUs. Table 2-3. Calculating Total Calorific Values Component BTU/hr Times Number Equals Installed Basic System Unit (typical) 2048 Disk Expansion Unit (typical) Monitor...

  • Page 27: Grounding Requirements

    Grounding Requirements The system rack must have a dedicated ground attached to the power distribution panel. The ground wire must have an earth resistance of 100 ohms or less and depending on your local electrical code, a thickness of 38 mm or more.
